Remote and hybrid work have changed the way employees access company resources. Internal dashboards, cloud applications, development environments, and administrative tools are now frequently accessed directly through web browsers.
This makes me wonder what role should browsers play in a Zero Trust security model?
Zero Trust Network Access (ZTNA) moves away from automatically trusting users simply because they are connected to a company network. Instead, access decisions can consider identity, security policies, devices, and the specific resource being requested.
One example of this approach is QuickZTNA:

Identity is an important part of Zero Trust, especially when employees use different applications and require different permissions. Organizations can connect identity providers and SSO systems with their access infrastructure.
Here is an example of identity integrations:

But the browser is often the actual interface employees use to access protected applications. This raises an interesting question about whether browsers could contribute additional security information when access decisions are being made.
Device security is another consideration. Even when a user's identity is verified, organizations may want to check whether the device meets certain security requirements before granting access.
Device posture is one approach to this:

As more business applications move to the web, browsers such as Firefox could potentially play a larger role in identity-aware and device-aware security.
At the same time, deeper integration raises important questions about privacy and how much device information a browser should expose.
What do you think? Should browsers like Firefox become more involved in Zero Trust access decisions, or should these security controls remain completely separate from the browser?
