CIS Internet Explorer 11 Benchmark, continuously evidenced.

The CIS Microsoft Internet Explorer 11 Benchmark v1.0.0 defines 156 controls covering IE 11 hardening: security zones, ActiveX restrictions, cookie handling, certificate validation, and Group Policy enforcement. While IE 11 has been retired by Microsoft, many enterprise environments retain it for legacy line-of-business applications via Edge IE Mode or standalone IE installations.

Frequently Asked

Internet Explorer 11 questions, answered directly.

IE 11 is retired. Why is this benchmark still relevant?

Microsoft retired IE 11 as a standalone browser, but many enterprise environments retain IE 11 functionality via Edge IE Mode for legacy line-of-business applications. The CIS benchmark applies to both standalone IE 11 installations (still present in some environments) and to Edge IE Mode configurations.

Does this benchmark apply to Edge IE Mode?

Largely yes. Edge IE Mode runs the IE 11 rendering engine within Edge, inheriting most IE 11 configuration. The CIS Edge benchmark covers IE Mode-specific configuration (site lists, IE Mode policies); this IE 11 benchmark covers the underlying IE engine behavior.

Should I plan to retire IE 11 / IE Mode usage?

Yes. Both Microsoft and CIS recommend migrating away from IE 11 functionality. Edge IE Mode is a transitional bridge. For new line-of-business applications, modern Edge or Chrome should be the deployment target. The CIS IE 11 benchmark addresses the existing footprint that organizations need to maintain compliance for during the transition.
