What it is
Unauthorized tools typically emerge when employees install browser extensions, SaaS tools, scripts, or utilities to improve productivity without going through an approval process. While often well-intentioned, these tools operate outside governance controls and may handle sensitive data, integrate with core systems, or introduce unknown dependencies.
Why it matters
Unauthorized tools expand the attack surface in unpredictable ways. They can bypass security controls, introduce vulnerable code paths, or leak data to third parties. Because they are undocumented and unmanaged, they are rarely patched, monitored, or assessed for risk, making them attractive entry points for attackers.
How to reduce risk
- Maintain an up-to-date inventory of approved tools and services.
- Monitor for new applications, extensions, and integrations.
- Enforce least-privilege access for third-party tools.
- Educate employees on secure tooling and approval processes.
