No IPS log or Anomaly log recorded

Hello Mustapha

First, make you enabled the required logs:

• Enable All traffic logs under Log &  Report > Log Setting
• Enable All traffic logs at policy level where you have enabled IPS and AV profiles

Try to download a dummy virus file like eicar, here FG should block it and you should find the log under Log & Setting > AV.

In case you didn't enable SSL deep inspection then you will only catch viruses and attacks under http and other unencrypted protocols.

So if you want to catch viruses and attacks under https you need to enable SSL deep inspection.
