Browser extension risk reduction guidance for credential theft and SaaS compromise
Defensive Guidance
Summary
Hide ▲
Show ▼
A new browser-extension hardening playbook recommends allow lists, permission audits, monitoring, and staged updates to cut credential theft and SaaS compromise risk. It treats browser add-ons as part of the organization's identity and cloud attack surface, not just endpoint software. The guidance matters because silent extension updates can turn a trusted add-on into a stealthy access path without users noticing.
