What is Shadow IT?

Shadow IT refers to the use of technology systems, devices, software, applications, or services—especially cloud-based tools—without the knowledge or explicit approval of an organization’s IT department. It typically arises when employees adopt third-party solutions to enhance productivity or circumvent limitations of sanctioned tools, often using personal accounts or credit cards.

‍

Common examples of Shadow IT include using personal file-sharing services (like Dropbox), messaging platforms (like WhatsApp or Signal), or online productivity tools (like Trello or Notion) for business-related tasks. While often well-intentioned, this decentralized approach to technology adoption creates significant security, compliance, and operational risks.

‍

Because IT and security teams lack visibility into these tools, they cannot verify whether proper security controls—such as encryption, access management, or data residency protections—are in place. As a result, Shadow IT can expose the organization to data breaches, loss of intellectual property, regulatory violations, and unsecured integrations. Additionally, it can result in duplicate tools, inconsistent workflows, and increased software spending.

‍

However, Shadow IT also highlights legitimate needs and friction points in an organization’s existing tech stack. Employees turn to unsanctioned tools because they help them work more efficiently or solve immediate problems. Rather than cracking down indiscriminately, forward-thinking IT and security leaders use Shadow IT discovery as a way to surface unmet needs.

‍

Managing Shadow IT effectively requires a combination of:

  • Continuous discovery tools that surface unsanctioned applications and services.
  • Clear governance policies to guide safe adoption of new technologies.
  • Employee education on risks and compliance requirements.
  • Offering secure, user-friendly alternatives that meet employee needs without sacrificing oversight.

By transforming Shadow IT from a blind spot into a feedback loop, organizations can reduce risk while supporting agility and innovation.
