Nudge Security vs. CASB

Looking for a CASB alternative? Discover more shadow SaaS faster with our patented, perimeterless approach to SaaS security and governance.

What is Nudge Security?

Nudge Security is a perimeterless SaaS security and governance platform for distributed, cloud-first organizations. Our patented approach to SaaS discovery provides visibility of all cloud and SaaS assets, including historical, off-network, and unmanaged SaaS use.

Automated workflows and purpose-built playbooks make SaaS governance at scale a breeze by orchestrating and distributing admin work to the business units and individuals who manage SaaS apps day to day.

Nudge Security uses modern principles of behavioral psychology to work with employees—not against them—guiding them toward safe, compliant SaaS use without disrupting the pace of productivity.

What is CASB?

Cloud access security brokers (CASBs) sit between SaaS applications and SaaS users to enforce a broad set of inline enterprise security policies related to how applications are accessed.

CASBs are just one component of a secure access service edge (SASE) or secure service edge (SSE) platform. These solutions focus on controlling and securing access to enterprise cloud services and SaaS applications, often by using principles of zero trust.

Sample CASB vendors include Netskope, Palo Alto Networks, and Zscaler.

The CASB challenge

A shapeshifting network edge

Digital transformation over the past decade has shifted the network perimeter from the data center to the cloud. Today, the network edge extends even further, to the thousands of cloud environments operated by your SaaS providers—and to every remote employee and contractor who accesses those environments over the internet.

Cloud access service brokers (CASBs), cloud security gateways (CSGs), and secure web gateways (SWGs) emerged to manage and secure traffic and data between end users on a corporate network and the internet, cloud services, and SaaS applications. But, maintaining this network perimeter becomes increasingly untenable as SaaS use sprawls beyond a handful of key enterprise SaaS applications and as remote and hybrid workers connect directly to new and unknown SaaS applications off network and on personal devices. It’s no longer feasible to force all of your workforce’s internet traffic through this sieve.

This approach of trying to separate the good internet from the bad at an ever-changing network edge and forcing all user traffic through it is like trying to dam an ocean.

Related CASB terms

Modern network security is served with a hearty bowl of acronym soup. Here are some terms related to CASB that you might come across.


SASE stands for secure access service edge. An acronym coined by the analyst firm, Gartner, SASE describes a market category for technology solutions that provide an integrated ecosystem of enterprise networking (SD-WAN) and network security technologies, such as CASB, FWaaS, SWG, and ZTNA technologies.


SSE refers to the security service edge. Also coined by Gartner, it refers to the security side of SASE, encompassing multiple network security technologies (CASB, FWaaS, SWG, ZTNA, etc.) all integrated into a single, cloud-based platform.


Firewall as a service (FWaaS) describes a cloud-based network firewall. FWaaS vendors often provide next-generation firewall (NGFW) capabilities, including intrusion prevention and detection (IPS / IDS), application-aware security policy enforcement, URL filtering, threat intelligence and advanced malware prevention capabilities. Definition from TechTarget

Web proxy

A web proxy is a server that acts as an intermediary between a user and the internet. It can be used to bypass internet censorship, protect privacy, and improve network performance by caching frequently accessed web pages.


Secure web gateways filter unwanted software and malware from user-initiated Internet traffic and enforces corporate and regulatory policy compliance. These gateways include URL filtering, malicious-code detection and filtering, and application controls for popular web-based applications, such as instant messaging (IM) and Skype. Definition from Gartner


Don’t call zero trust a technology product (unless you want a self-appointed ZT brigade on your tail.) Zero trust is a security model popularized by Google’s BeyondCorp implementation. Zero trust architectures and ZTNA solutions are based a philosophy of “never trust, always verify,” which effectively shifts access controls and policies from the point of a user joining a network to a per-application or per-resource or other more granular basis.
