: Mitigation of system memory loops and unexpected CPU spikes generated by the internal proxy daemon when mixing flow-based application controls with proxy-based web inspection.
Additionally, this release refined the implementation of ZTNA (Zero Trust Network Access) agents. As organizations began shifting toward perimeter-less security models, the 7.0.9 update smoothed out the connectivity and authentication processes for ZTNA, making the transition from traditional VPNs to Zero Trust architectures more seamless for endpoint users. These iterative improvements enhanced the overall user experience, reducing the administrative overhead required to manage complex security policies. Complete Guide to FortiOS 7
Previous versions in the 7.0.x branch occasionally suffered from "conservancy mode" triggers due to memory leaks in the WAD (Web Application Daemon) and IPS (Intrusion Prevention System) engines. FortiOS 7.0.9 delivers refined memory allocation logic, significantly reducing instances of unexpected conservancy mode entry on mid-range and entry-level FortiGate models (such as the FortiGate 40F, 60F, and 100F).

Resolved an issue where WAD processes consumed unusually high CPU, multiplying child processes that failed to release resources gracefully. Bug ID 840940
If you are currently evaluating or maintaining a FortiGate 7.0.9 deployment, following these best practices will ensure optimal performance and ironclad security. 1. Perform a Structured Upgrade
FortiGate 7.0.9 is a crucial, security-centric update. If your infrastructure relies on the 7.0.x release train—and particularly if you have SSL-VPN endpoints enabled—upgrading to 7.0.9 (or its subsequent service releases like 7.0.10+) is non-negotiable due to the severe vulnerabilities it patches. It provides a stable, highly secure foundation for enterprise firewalls, ensuring your hardware acceleration operates optimally while keeping advanced threats locked outside your perimeter. To help tailor this deployment, let me know: What are you currently using? What firmware version are you upgrading from?
