Hello @Yang, Steven ,
I understand that you would like to know if there is a way to apply the 'Bypass list' in IDPS blade to specific signature only.
I discussed this requirement with Azure Firewall Product Group team, and they mentioned that as of today, this is not possible.
Refer: https://learn.microsoft.com/en-us/azure/firewall/premium-features#idps
IDPS bypass for specific signatures is on our roadmap but we have no ETA to share yet.
Kindly let us know if the above helps or you need further assistance on this issue.
Please "Accept the answer" if the information helped you. This will help us and others in the community as well.
