TL;DR: Browser security in a bring-your-own-browser model depends on execution control, with Airlock Digital highlighting approved versions, separate extension approval, and ongoing review. Browser governance has to track extensions, version drift, and revocation as software changes over time.
Editorial analysis by NHI Mgmt Group, based on content published by Airlock Digital: “Bring Your Own Browser Without Security Compromise”.
Key questions
Q: Why do approved browsers still create risk if extensions are unmanaged?
A: Because the browser becomes a trusted execution surface for code that can read pages, sessions, cookies, and sometimes downloads or history.
Q: What are the signs that browser approval policy is failing?
A: Look for users installing unsupported browser versions, sideloaded or unpacked extensions, store listings that do not match approved IDs, and extensions that remain active after the trust basis changes.
Q: How should security teams govern browser extensions in zero trust environments?
A: Security teams should treat browser extensions as privileged software with access to user data, sessions, and web content.
Practitioner guidance
- Define an approved browser and version list Allow only supported releases from approved publishers and block older versions with known vulnerabilities from executing.
- Enforce deny by default for extensions Require explicit approval before any extension can run, and treat each browser-specific extension ID as a separate decision.
- Build an intake process for new extensions Record the business purpose, users, permissions, exact extension ID, browser, version, and source before deciding whether approval is warranted.
Bottom line: Browser security in a bring-your-own-browser model depends on execution control, not just policy statements.

Browser extension governance is now part of identity governance. A browser extension can touch sessions, cookies, and authenticated web applications, which means it can influence how human identities are used after login. That makes extension approval a governance decision about access scope, not just a desktop control. Teams that own IAM and endpoint policy need a shared view of which extensions can operate inside business workflows, because browser trust can become identity trust in practice.
A question worth separating out:
Q: Should organisations keep one corporate browser instead of managing user choice?
A: Not necessarily. A forced corporate browser can simplify control, but it often increases workflow friction and adoption problems. A governed bring-your-own-browser model can work better when the organisation can enforce approved versions, block untrusted extensions, and review exceptions quickly.
