TL;DR: Browser-based activity is increasingly the first step in credential theft, malware delivery, and data exfiltration because users act inside authenticated sessions, install high-permission extensions, and download files outside software governance, according to Securden. Treating the browser as a governed application, rather than a simple utility, changes the blast radius of everyday work.
NHIMG editorial — based on content published by Securden: browser-based risk and endpoint privilege control
By the numbers:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
- 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage.
Questions worth separating out
Q: How should security teams govern browser-based access to sensitive applications?
A: Treat browser-based access as part of the privileged access surface when it reaches cloud consoles, admin portals, or operational systems.
Q: Why do browser sessions create identity risk even when passwords are strong?
A: Browser sessions carry authenticated state such as cookies and tokens that can be replayed by an attacker after theft.
Q: What breaks when browser extensions are not governed in enterprise environments?
A: The main failure is that the browser becomes an unmanaged privilege zone.
Practitioner guidance
- Classify the browser as a governed application Map browser activity to your endpoint privilege model, then define which websites, download types, and extension categories are allowed for each user group.
- Restrict extension installation by permission scope Allow only approved extensions that match a documented business need, and review requested permissions such as web content access, cookie access, and page modification before deployment.
- Control browser-initiated execution paths Block execution of unapproved downloads and script-spawned processes at the endpoint layer so a file cannot run just because it arrived through a browser.

Browser governance is now an identity control problem, not just an endpoint hygiene issue. The browser routinely carries authenticated state that can be replayed, delegated, or stolen, which places it closer to IAM and PAM than many teams assume. When a browser session becomes the path to SaaS, cloud consoles, and internal apps, the control objective shifts from malware blocking to session governance. Practitioners should therefore treat browser activity as part of the identity control stack.
A question worth separating out:
Q: Who is accountable when browser-based exfiltration or token theft occurs?
A: Accountability usually sits across endpoint security, IAM, and application owners because browser risk crosses all three domains. Teams should define who owns extension policy, who owns session and token protection, and who owns forensic review, because fragmented ownership is a common reason browser risk stays unmanaged.
