Azure WAF Detection Mode: No Protection, Only Logging - Understanding the Security Risk
By

Plain bagel done well. Pleasantly substantive.
Summary
The article explains that Azure WAF's Detection mode is often misunderstood as providing partial protection when it actually offers no protection at all. Detection mode only logs potential attacks without blocking them, creating a false sense of security. Many organizations remain stuck in Detection mode due to defaults, tuning complexity, and misleading dashboard indicators. The article clarifies the technical reality of Detection mode versus Protection mode and warns about the security risks of this common misconfiguration.
Key quotes
· 5 pulledDetection mode is not a weaker version of protection. It is the complete absence of protection.
Your security posture dashboard says WAF is enabled. Technically, that's true. Detection mode is not a weaker version of protection.
Most teams think a WAF in Detection mode is partially protecting them. It isn't.
Your WAF is enabled. Your dashboard is green. And every attack hitting your application is going straight through to the backend.
Somewhere in your Azure environment, there is probably a WAF policy sitting in Detection mode. Not because someone made that call explicitly.
