What is SaaS security? Components, risks, and how to build a program

SaaS security is the discipline of discovering, governing, and protecting an organization's SaaS applications, user identities, integrations, and data from unauthorized access, misconfigurations, and cyber threats. A complete SaaS security program covers discovery, identity and access governance, continuous posture monitoring, integration oversight, data protection, and lifecycle management.

‍

Key takeaways

• SaaS security is not a subset of cloud security — it is a distinct discipline focused on the applications your organization uses, not the infrastructure it runs.
• Identity has replaced the network perimeter as the primary control plane. Attackers target SaaS accounts, not servers.
• The average enterprise uses hundreds of SaaS applications; only a fraction are managed by IT, and the rest introduce unmanaged access risk.
• Misconfigurations and unreviewed OAuth grants are the leading sources of SaaS data exposure, ahead of direct external attacks.
• Compliance frameworks including GDPR, HIPAA, and SOC 2 Type 2 all impose specific obligations on how organizations manage SaaS access, data, and configurations — obligations that traditional IT controls are not equipped to satisfy.

Why SaaS security is different from every other security problem

SaaS security is different from every other security problem because its attack surface — applications, identities, and integrations — exists entirely outside the infrastructure your security team controls.

‍

Traditional security was built for a world where the network was the perimeter. Firewalls, VPNs, and CASBs were designed with a single controlling assumption: your data flows through infrastructure you manage. That assumption is no longer valid.

‍

In most organizations, employees adopt SaaS tools without IT approval, connect those tools to each other through OAuth grants, and access everything from personal devices on home networks. The attack surface is no longer the network edge — it is the sum of every identity, OAuth token, and application configuration across an estate that no team has fully mapped.

‍

SaaS security exists to address what traditional controls structurally cannot see. It is not a replacement for perimeter security — it covers a categorically different attack surface.

‍

Three shifts make SaaS security distinct:

‍

Identity replaced the network as the perimeter. SaaS applications are accessed entirely through identity-based mechanisms: passwords, MFA, SSO tokens, and OAuth grants. An attacker with valid credentials can access your Salesforce instance from anywhere in the world. There is no firewall to cross.

‍

Shadow IT is structural, not a policy failure. Employees adopt tools because they need them. In a SaaS world, this happens dozens of times per day across departments that operate independently of IT. Security programs that try to stop this consistently fail. Programs that gain visibility over it and create fast, governed intake paths succeed.

‍

Integrations expand the blast radius. When an employee connects an automation tool to Slack, Google Drive, or Salesforce via OAuth, they are creating an access pathway that persists indefinitely. A breach at any integrated vendor does not just compromise that vendor — it potentially compromises every application connected to it.

‍

Why SaaS security matters — and what's at stake

The business risk

SaaS breaches follow a pattern that network-oriented security teams consistently underestimate. The initial access point is almost never a server exploit. It is a compromised account, an overprivileged OAuth grant, a misconfigured sharing setting, or an employee who left the company six months ago and still has active credentials across eleven applications.

‍

The consequences are real — and increasingly driven by AI tools that employees connect to corporate systems without security review. When OpenClaw AI, an open-source agent platform, surpassed 100,000 GitHub stars in 72 hours, it was also requesting highly privileged OAuth access to tools like Google Calendar, 1Password, and Slack. Researchers later discovered a misconfigured database exposing 1.5 million API authentication tokens and 35,000 email addresses — plus remote code execution vulnerabilities allowing agent hijacking. The incident illustrates a structural gap: AI agents request the same OAuth permissions as any other third-party app, but most organizations have no centralized visibility into which agents hold access to what. Traditional perimeter controls were not built to catch this — read Nudge's full breakdown of what the OpenClaw AI incident means for enterprise SaaS security →

‍

The OpenClaw AI breach, the Gainsight OAuth compromise, the browser extension harvesting campaigns, and the CamoLeak prompt injection attack are not outliers — they represent the four most common SaaS attack vectors playing out in real enterprise environments:

‍

Identity attack: Attackers used custom phishing kits for voice-based social engineering — keeping victims on a live phone call while controlling their browser in real time to relay stolen Okta SSO credentials and bypass MFA. Number-matching push MFA remained vulnerable because attackers simply directed victims which option to select. Downstream SaaS access was the objective throughout — read the full breakdown of the Okta vishing attack →

‍

OAuth supply chain: ShinyHunters exploited a stolen Gainsight OAuth token — obtained from previously compromised Salesloft and Drift support data — to access approximately 285 Salesforce customer instances without ever touching Salesforce's platform directly. One compromised vendor; unlimited blast radius across every customer connected to it — read how the Gainsight OAuth compromise unfolded →

‍

Browser extension supply chain: Urban VPN Proxy and related extensions (8M+ combined users) were discovered silently capturing complete AI chat prompts, responses, and metadata — transmitting them to external servers regardless of whether the VPN feature was active. The harvesting operated independently of the extension's core function — removal was the only mitigation. Read Nudge's analysis of how VPN and Adblock extensions silently harvested AI chat data →

‍

AI agent prompt injection: A vulnerability called CamoLeak in GitHub Copilot Chat allowed attackers to inject hidden instructions into pull request comments. When developers reviewed the affected PRs, the AI executed those instructions — encoding private source code, credentials, and internal documentation into covert image URL sequences and exfiltrating them through GitHub's own Camo proxy. The attack exploited the developer's own repository access permissions — read the full CamoLeak analysis →

‍

The shared responsibility model

Every SaaS vendor operates under a shared responsibility model — a division of security obligations between the vendor and the customer. What most organizations don't fully grasp is where their responsibility begins.

‍

SaaS vendors are responsible for the security of the platform: the infrastructure, the application layer, the physical data centers. Customers are responsible for everything that happens inside their tenant: who has access, what permissions they hold, how data is configured and shared, which third-party apps are connected, and whether users who left the organization have been properly offboarded.

‍

Misconfigurations, unauthorized integrations, and identity sprawl are customer-side failures. No SaaS vendor's security program catches them. That is the gap SaaS security programs exist to close.

‍

Compliance exposure

Organizations operating under GDPR, HIPAA, SOC 2 Type 2, or PCI DSS face specific SaaS-related obligations that many compliance programs are not equipped to address.

‍

GDPR requires demonstrable control over who can access personal data and for what purpose — including access through third-party SaaS integrations and OAuth grants.

‍

HIPAA requires access controls, audit trails, and data protection for any system that touches protected health information — including the SaaS tools where PHI is stored, processed, or shared.

‍

SOC 2 Type 2 requires continuous evidence of access controls, configuration management, and incident response — not point-in-time documentation, but ongoing operational practice.

‍

The shared responsibility model means that when a SaaS-related compliance failure occurs, the customer bears the regulatory consequence — not the vendor. Understanding what your organization owns in that model is the first step to closing the gap.

‍

The seven components of a SaaS security program

SaaS security is not a single tool or practice. It is a program with seven interdependent components. Most organizations have partial coverage on two or three. The gaps between them are where incidents happen.

‍

1. Discovery and inventory

Complete SaaS visibility requires finding more than the applications your IT team provisioned. A thorough inventory includes SSO-connected applications, password-based tools employees use directly, OAuth applications connected to corporate systems, browser extensions with account-level access, and AI tools employees have authorized to access company data.

‍

Nudge customers discover an average of 50,000+ unique SaaS assets on Day One — compared to the hundreds of apps surfaced by tools that rely on SSO and prior knowledge alone. Discovery is not a one-time project. New tools are adopted continuously, and the inventory must reflect that in real time.

‍

2. Identity and access governance

In a SaaS environment, every user lifecycle event — joining, changing roles, departing — needs to trigger identity actions across every SaaS application in the estate. A mature identity governance approach covers MFA enforcement across all applications, SSO consolidation, automated onboarding and offboarding tied to HR systems, minimum-privilege access enforcement, and management of non-human identities.

‍

Non-human identities — API keys, service accounts, and automation tokens — accumulate faster than they are cleaned up. Unlike human accounts, they often have no expiration date, no MFA requirement, and no offboarding process. They represent persistent, privileged access that attackers specifically seek out, and that most SaaS identity and access management programs systematically miss.

‍

3. SaaS Security Posture Management (SSPM)

SaaS configurations do not stay where you set them. Product updates change default settings. Admins make exceptions that are never reversed. New features ship with permissive defaults that no one reviews. SSPM tools continuously monitor SaaS configurations against security baselines, surfacing drift before it creates exposure.

‍

The critical distinction: SSPM covers posture and configuration. It does not cover discovery, identity lifecycle, or integration governance. Organizations that treat SSPM as a complete SaaS security solution have meaningful coverage gaps — see what SSPM covers and where its coverage ends.

‍

4. Integration and OAuth governance

Every OAuth grant is a trust decision that persists until someone explicitly revokes it. When an employee connects an automation platform, AI writing tool, or third-party integration to Slack, Google Drive, or Salesforce, they are authorizing ongoing access to corporate data — often with broader permissions than the task requires.

‍

Most organizations have no centralized visibility into which third-party applications hold OAuth access to their corporate tools. The scope of this problem is growing rapidly: AI tools, in particular, request broad access to corporate data sources as part of their standard onboarding. Managing integration risk requires a complete map of what is connected to what, by whom, and under what permissions — see how teams manage OAuth risks and SaaS-to-SaaS integration exposure at scale.

‍

In the wild: In November 2025, ShinyHunters exploited a stolen Gainsight OAuth token — obtained from previously compromised Salesloft and Drift support data — to access approximately 285 Salesforce customer instances without ever touching Salesforce's platform directly. Salesforce revoked all associated tokens, but the breach illustrated exactly how OAuth supply chain attacks work: one compromised vendor, unlimited blast radius across every customer connected to it — read how the Gainsight OAuth token compromise exposed 285 Salesforce instances →

‍

5. Data governance and sharing controls

SaaS data exposure rarely begins with an external attack. More often it is quiet accumulation: public links created for a short-term need and never revoked, files still accessible to former employees, corporate data uploaded to AI tools, shared drives with stale external collaborators. A mature data governance approach includes restrictive sharing defaults with regular audit cycles, public link monitoring, external collaborator governance, and AI tool data access controls covering what corporate data AI systems can access, retain, and process.

‍

6. Threat detection and response

SaaS threats target accounts, not infrastructure. The signals that matter are unusual identity behavior, OAuth token abuse, anomalous file downloads, and privilege escalation patterns — not network traffic anomalies. Response in a SaaS context means resetting sessions and tokens, revoking OAuth access, evaluating data exfiltration pathways, and tracing identity behavior across the full application estate. Traditional incident response playbooks are built around server access. SaaS incidents require a fundamentally different investigation approach.

‍

7. Governance and lifecycle management

SaaS environments change too fast for periodic reviews. A complete governance program includes app request and approval workflows that give employees a clear, fast path to new tools — reducing shadow IT by making the governed option easier than the workaround — vendor risk assessments before OAuth access is granted, periodic access reviews, and automated offboarding that covers all SaaS applications, not just those connected via SSO.

‍

Common SaaS security risks

Most organizations have some coverage on obvious attack vectors. The risks that consistently go unaddressed are the structural ones — the places nobody is looking because no existing tool covers them.

‍

Shadow IT and shadow AI. Employees adopt tools IT has not provisioned. This now includes AI tools that request broad OAuth access to corporate systems. An employee using an AI writing assistant connected to Gmail and Google Drive is creating data exposure that does not appear in any sanctioned inventory. Shadow AI is shadow IT with a larger data access footprint.

‍

SaaS supply chain risk. OAuth integrations create chains of implicit trust. A breach at a third-party vendor does not just expose that vendor's systems — it exposes every SaaS application that vendor can access via OAuth. The blast radius depends entirely on what permissions were granted and never reviewed. Most organizations cannot answer the question "which of our SaaS tools does this vendor have access to?" without significant investigation.

‍

Misconfiguration drift. Security posture does not stay where you set it. A baseline established during implementation will drift as product updates ship, as admins make one-off exceptions, and as new features roll out with permissive defaults. Point-in-time audits produce a snapshot that may bear no relationship to the configuration state six months later.

‍

Non-human identity sprawl. API keys, service accounts, and automation tokens accumulate without expiration dates, MFA requirements, or offboarding processes. They represent persistent, privileged access and are among the most frequently targeted entry points in SaaS-specific attacks.

‍

Orphaned accounts. Former employees with active SaaS credentials represent one of the most persistent and underappreciated risks in SaaS security. Offboarding that covers only SSO-connected applications leaves non-SSO tools, OAuth grants made under the departed employee's account, and integrations they created still active.

‍

How AI is expanding the SaaS attack surface

AI tools are SaaS applications — adopted through the same informal channels as other shadow IT, requesting broader data access than most tools, and now beginning to act autonomously on behalf of users. The security risk is not that AI is categorically different, but that it is moving faster than governance programs have followed.

‍

AI tools are SaaS tools

The most important framing shift for security teams: AI security is not a separate discipline from SaaS security. AI tools are SaaS applications. They are adopted through the same informal, employee-led pathways as other shadow IT. They connect to corporate data through OAuth. They accumulate permissions that persist long after the use case that justified them. The governance gaps that create SaaS risk are the same gaps that create AI risk.

‍

What makes AI tools distinctive is the access profile they request. An AI writing assistant connected to Gmail and Google Drive can read, summarize, and generate content on behalf of the user — with access to everything in those systems. An agentic AI tool connected to Slack, Notion, and a project management platform can act autonomously across all of them, creating, editing, and sharing content without a human approving each action.

‍

What enterprise AI adoption actually looks like

Based on telemetry across enterprise environments, AI tool adoption is more widespread — and more heterogeneous — than most IT teams realize:

• OpenAI is present in 96% of organizations; Anthropic in 77.8%
• Meeting intelligence tools (Otter.ai, Read.ai) appear in 62–74% of organizations — recording calls that routinely include sensitive business discussions
• Emerging agentic platforms (Manus, Lindy, Agent.ai) are appearing in enterprise environments before any governance framework exists for them
• 17% of prompts include file uploads or copy-pasted content — and of those sensitive data events, 47.9% involve secrets or credentials, 36.3% financial information, and 15.8% health-related data

(Source: Nudge Security AI adoption analysis across enterprise environments)

‍

The security implication: employees are actively feeding corporate data into AI tools at scale. In most organizations, there is no inventory of which AI tools are in use, no review of what OAuth access they hold, and no mechanism for detecting when sensitive data has been uploaded — a pattern Nudge's research on AI adoption and enterprise risk governance documents in detail.

‍

The agentic AI frontier

The next phase of AI risk is agentic tools — systems that do not just respond to prompts, but act autonomously on behalf of users across multiple applications. An AI agent with OAuth access to Slack, GitHub, Google Drive, and a CRM does not just read data. It can send messages, create records, modify files, and trigger workflows — all without a human approving each action.

‍

From a SaaS security standpoint, an AI agent is a non-human identity with OAuth access and autonomous behavior. It needs the same governance treatment as any other integration: visibility into what access it holds, review of whether that access is appropriate, and a mechanism to revoke it if the behavior is unexpected. Most organizations do not yet have any of this in place for agentic tools.

‍

The Model Context Protocol (MCP) is emerging as a standard interface for connecting AI agents to enterprise applications. It expands the scope of what agents can access — and therefore expands the scope of what SaaS security programs need to govern.

‍

What this means for SaaS security programs

AI does not require a separate security program. It requires extending existing SaaS security practices to cover a new category of application with distinctive access patterns:

• Discovery must include AI tools, not just traditional SaaS — including tools employees have connected directly without IT review
• OAuth governance must cover AI agents, which often request broad scopes that would trigger review if a traditional tool requested them
• Non-human identity management must extend to AI agents acting on behalf of users — including agents that were authorized by employees who have since left the organization
• Data governance must address what corporate information employees are uploading to AI tools, and whether those tools retain it

The organizations building this capability now are ahead of a problem that is growing significantly faster than most security programs are tracking.

‍

SaaS security and compliance: GDPR, HIPAA, and SOC 2

Regulatory compliance in a SaaS environment is a customer-side responsibility. The shared responsibility model means that when a compliance audit reveals unauthorized access, a misconfigured data-sharing setting, or an unreviewed third-party integration, the regulatory consequence falls on your organization — not on the SaaS vendor.

‍

Understanding what each framework requires from your SaaS estate is the starting point.

‍

GDPR imposes requirements on data access, processing purpose, and third-party data sharing. For SaaS environments, this means documented justification for who can access personal data, visibility into what personal data third-party integrations can reach, and the ability to respond to data subject requests across the full SaaS estate — not just the core enterprise systems.

‍

HIPAA applies to every SaaS application where protected health information is stored, processed, or transmitted — including integrations those applications carry. Most compliance programs underestimate this scope: a clinical team's project management tool connected to a Google Workspace that contains PHI is within scope. HIPAA requires access controls, audit trails, encryption, and breach notification procedures across this full footprint. Business Associate Agreements (BAAs) with each SaaS vendor in scope are required — and are a common gap in organizations that onboard SaaS tools informally.

‍

SOC 2 Type 2 requires continuous operational evidence of security controls — not a point-in-time assessment, but ongoing demonstration that access controls, configuration management, monitoring, and incident response are operating as described. SaaS environments are among the most difficult to demonstrate continuous compliance for, because configurations change with every product update and every admin decision.

‍

PCI DSS requires strict controls over any environment where cardholder data is accessed or processed. In a SaaS context, this includes any application that touches payment workflows, customer data, or financial records — and all OAuth integrations those applications carry.

‍

The practical implication across all four frameworks: compliance requires operational visibility that most SaaS estates do not have. Discovery, identity governance, posture monitoring, and integration governance are not just security controls — they are the evidence base for compliance. The Cloud Security Alliance (CSA) identifies SaaS misconfigurations and inadequate access management as two of the top threats to cloud environments, a finding that maps directly to the customer-side obligations each of these frameworks imposes. The SaaS security best practices checklist translates these obligations into operational controls.

‍

Zero Trust and SaaS security

Zero Trust is an architecture principle, not a product. Its core premise — "never trust, always verify" — maps directly onto the SaaS security problem, because SaaS environments have no perimeter to trust in the first place.

‍

Applying Zero Trust principles to a SaaS estate means:

‍

Identity verification at every access point. Every user, every device, every application requesting access to corporate SaaS tools is verified before access is granted — regardless of where the request originates. VPN access does not imply SaaS access. Being inside the corporate network does not imply trust.

‍

Least privilege as a continuous practice. Access rights are scoped to the minimum necessary for each user's current role — and are reviewed and adjusted as roles change. Least privilege applied at onboarding but never reviewed at role changes or departure produces accumulating over-permission that attackers exploit.

‍

Continuous validation, not one-time authentication. Zero Trust assumes that initial authentication is not sufficient. Session behavior, access patterns, and device posture are evaluated continuously. Anomalous behavior triggers re-verification or session termination rather than waiting for a human to notice.

‍

Explicit authorization for every integration. Every OAuth grant is an explicit trust decision — not an implicit extension of user identity — and must be periodically reviewed and revoked when no longer needed.

‍

Zero Trust does not eliminate the need for the seven program components described above — it provides the governance philosophy that connects them. NIST SP 800-207 formalizes Zero Trust architecture principles for enterprise environments; applying them to a SaaS estate means treating every application, integration, and identity as untrusted until verified. Organizations that adopt Zero Trust as a principle and apply it systematically across their SaaS estate build the most resilient programs.

‍

How SaaS security tools compare

No single tool category covers the full SaaS security program. Understanding where each tool's coverage ends is as important as understanding where it begins.

• CASB — Inline access control and app usage visibility. Coverage ends at off-network access, SaaS configurations, and SaaS-to-SaaS integrations.
• SSPM — Configuration monitoring and compliance baselines. Does not cover identity lifecycle, discovery of unknown apps, or integration governance.
• SASE / SWG — Secure connectivity and conditional access. Not designed for application-level SaaS insight or posture management.
• IAM / IGA — Account lifecycle and identity-based threat detection. Cannot see SaaS configurations, sharing settings, or integration access.
• SaaS Security Platforms — Discovery, identity, posture, integrations, and governance in one view. Coverage depth and breadth varies significantly across vendors.

The most common failure mode is not choosing the wrong tool — it is assembling tools that each address a different slice of the problem without understanding the gaps between them. Shadow IT, unreviewed OAuth grants, and non-human identity sprawl persist specifically because they fall between the coverage boundaries of standard tool stacks. Gartner identifies SSPM as a key technology in modern cloud security programs, but emphasizes that posture management alone does not constitute a complete SaaS security strategy.

‍

What to look for in a SaaS security solution

Evaluating SaaS security solutions requires clarity on what problems you are actually trying to solve. The tool categories above each address different parts of the problem — and vendor marketing tends to obscure where coverage ends.

‍

A few questions that cut through the noise:

‍

What does "discovery" actually mean? Some tools discover applications connected via SSO and call it complete. A complete discovery approach finds SSO-connected apps, password-based apps, OAuth applications, browser extensions, and AI tools — including shadow IT that bypasses centralized controls entirely. In practice, the difference is dramatic: Nudge customers typically discover 50,000+ unique SaaS assets on Day One, compared to the hundreds of apps surfaced by tools that rely on SSO and prior knowledge alone.

‍

How does identity lifecycle work in practice? The gap between "we support offboarding" and "we automate offboarding across all SaaS applications including non-SSO tools" is where most organizations lose control. Clarify exactly which applications are covered, how non-SSO apps are handled, and whether the process requires manual steps.

‍

When does value start? Many SaaS security tools require weeks of onboarding, integrations with existing infrastructure, and configuration before they surface useful data. Day One visibility — a complete picture of the SaaS estate without lengthy setup — is a meaningful differentiator for organizations that have an immediate gap to close.

‍

What does the governance model look like for employees? Tools that block access create shadow workarounds. Tools that engage employees with context — explaining why a tool is risky, offering a governed alternative, or routing a new tool request through a fast intake process — reduce unmanaged access risk without the organizational friction that blocking creates.

Frequently asked questions

What is SaaS security?

SaaS security is the discipline of discovering, governing, and protecting an organization's SaaS applications, user identities, integrations, and data from unauthorized access, misconfigurations, and cyber threats. It addresses the applications your organization subscribes to and uses — not the infrastructure it runs.

‍

Why is SaaS security important?

Organizations now run the majority of their critical business operations through SaaS applications — HR, finance, sales, collaboration, engineering, and more. Each application represents an access point, a data repository, and a potential integration into the rest of the estate. An unsecured SaaS environment creates compounding risk at scale: one compromised account, one misconfigured sharing setting, or one overprivileged OAuth grant can expose data across dozens of connected systems. SaaS security closes visibility gaps that traditional network controls were never designed to address.

‍

Is SaaS security the same as cloud security?

No. Cloud security typically addresses infrastructure your organization operates: servers, containers, storage, and networking in IaaS and PaaS environments. SaaS security addresses applications your organization uses — Google Workspace, Salesforce, Slack, and thousands of others. The attack surfaces, controls, and tooling are fundamentally different.

‍

What is the shared responsibility model in SaaS security?

The shared responsibility model defines the division of security obligations between a SaaS vendor and its customers. SaaS vendors are responsible for securing the platform — infrastructure, application code, and physical data centers. Customers are responsible for what happens inside their tenant: access controls, configurations, data sharing settings, integrations, and identity lifecycle management. Misconfigurations, unauthorized OAuth grants, and orphaned accounts are customer-side failures that no vendor's security program catches.

‍

What is SSPM, and how does it relate to SaaS security?

SaaS Security Posture Management (SSPM) is a tool category that continuously monitors SaaS application configurations for misconfigurations, policy violations, and drift from security baselines. SSPM covers one component of a full SaaS security program — posture and configuration — and does not address application discovery, identity lifecycle management, or integration governance.

‍

How does Zero Trust apply to SaaS security?

Zero Trust applies directly to SaaS environments because SaaS has no perimeter to rely on. Applying Zero Trust to SaaS means verifying identity at every access point regardless of network location, enforcing least-privilege access that is continuously reviewed, validating session behavior continuously rather than trusting initial authentication, and explicitly authorizing every OAuth integration rather than treating it as an implicit extension of user trust.

‍

What is the difference between SaaS security and SaaS management?

SaaS management focuses on license optimization, cost reduction, and application rationalization — getting value from the tools you pay for. SaaS security focuses on risk: unauthorized access, misconfigurations, data exposure, and integration governance. Both depend on complete SaaS discovery, but their goals, tools, and stakeholders differ significantly.

‍

What should you do immediately after a SaaS security incident?

Immediate response to a SaaS security incident should focus on four actions: reset all active sessions and revoke OAuth tokens associated with the compromised account or application; trace the identity's activity across every connected SaaS application to determine lateral access; identify and revoke any data sharing or export actions triggered during the incident window; and conduct a cross-app identity review to find other accounts with similar privilege patterns that may have been targeted. Unlike server-based incidents, SaaS compromises rarely stop at one application — tracing the OAuth graph is essential for determining the full blast radius.

‍

What should I look for in a SaaS security audit?

A SaaS security audit should cover: complete application inventory including shadow IT and OAuth integrations, identity and access governance including MFA coverage and non-human identities, configuration posture across critical SaaS applications, integration and OAuth grant review, data sharing and external access settings, offboarding completeness for recent departures, and compliance posture against relevant frameworks. The scope depends on the organization's size, industry, and current maturity level; the SaaS security best practices checklist covers the full audit scope across all components.
