I’ve been experimenting with Neuvector WAF. However, I’ve noticed that malicious queries aren’t prevented most of the time. Observing random behavior for the same queries. and with the load valid requests are also failing with a 504 error sometimes.

Anyone is facing these kind of issues?

Just checking in again — has anyone experienced similar issues with NeuVector WAF?

I’m still seeing **inconsistent blocking of malicious requests** and occasional **504 errors on valid traffic** when the WAF is enabled. I’ve reviewed the logs and configs, but nothing obvious so far.

If anyone has faced something like this or has suggestions on what to look into (policies, version-specific bugs, etc.), it would really help. Thanks!
