Applying an aggressive IPS profile without prior testing can disrupt legitimate applications by incorrectly identifying normal traffic as malicious. To prevent disruptions while still monitoring for threats:
Enable IPS in "Monitor Mode" first:
This allows FortiGate to log and analyze potential threats without actively blocking traffic.
Administrators can review logs and fine-tune IPS signatures to minimize false positives before switching to blocking mode.
Verify and adjust signature patterns:
Some signatures might trigger unnecessary blocks for legitimate application traffic. By analyzing logs, administrators can disable or modify specific rules causing false positives.

neighbor-group:
This command is used to group multiple BGP neighbors with the same configuration, reducing redundant configuration.
Instead of defining individual BGP settings for each spoke, the administrator can create a neighbor-group and apply the same policies, reducing manual work.
neighbor-range:
This command allows the configuration of a range of neighbor IPs dynamically, reducing the need to manually define each spoke neighbor.
It automatically adds BGP neighbors that match a given prefix, simplifying deployment.

To minimize CPU and RAM usage while still enforcing security features like web filtering and application control, SSL certificate inspection mode is the best choice. SSL certificate inspection allows FortiGate to inspect only the SSL/TLS handshake, including the Server Name Indication (SNI) and certificate details, without decrypting the full encrypted payload. This enables features like web filtering and application control because FortiGate can determine the destination website or application based on SNI and certificate information. It significantly reduces system load compared to full SSL inspection, which requires full decryption and re-encryption of traffic.
