It is important to clarify that bypassing network security measures like FortiGuard Intrusion Prevention Systems (IPS) is generally a violation of organizational security policies and could lead to disciplinary action or security risks [2].

The most common method for individual users is routing traffic through an external server. By using a Virtual Private Network (VPN) or a secure proxy, the traffic is encrypted before it hits the FortiGate firewall. Since the firewall cannot inspect the encrypted payload of the VPN tunnel, it often cannot apply specific IPS signatures to the traffic [3, 4]. 2. HTTPS/SSL Inspection Gaps
