Blocking Ultrasurf Application
Other competitor firewall is doing SSL inspection first then Access Rule Policy. When I tried by our ASA5506 with Firepower 6.0, creating SSL decryption with Internal CA, then applied that SSL Policy to Access Rule, unfortunately still it cannot be block. Our AMP for endpoint can successfully block Ultrasurf Apps.
