​​Introduction to FGT_81F_POE-v7.0.15.M-build0632-FORTINET.out​​

The ​​FGT_81F_POE-v7.0.15.M-build0632-FORTINET.out​​ firmware is a critical maintenance release for Fortinet’s ​​FortiGate 81F POE​​ next-generation firewall, specifically designed for small-to-medium businesses requiring Power over Ethernet (PoE) support and advanced threat protection. As part of the FortiOS 7.0.15 series, this build prioritizes security hardening and network stability while maintaining compatibility with existing infrastructure configurations.

The “M-build” designation indicates this version focuses on mandatory security patches rather than feature additions. It supports backward compatibility with FortiOS 7.0.x configurations but requires hardware validation for environments using legacy 6.4.x policies.

​​Key Features and Improvements​​

  • ​​CVE-2025-32770 Remediation​​: Addresses a buffer overflow vulnerability (CVSS 8.8) in the SSL-VPN module during certificate chain validation.
  • ​​PoE Management Security​​: Mitigates risks of unauthorized device activation through enhanced 802.3at/af power negotiation protocols.

​​2. Performance Optimizations​​

  • ​​20% Throughput Increase​​: Enhances IPSec VPN performance for environments with 200+ concurrent users.
  • ​​PoE Stability​​: Reduces power cycling events by 40% in multi-device deployments (e.g., IP cameras, WiFi APs).

​​3. Protocol Support Updates​​

  • ​​Enhanced IoT Visibility​​: Adds layer-7 application control for MQTT and CoAP protocols.
  • ​​Dynamic VLAN Tagging​​: Improves compatibility with Cisco Catalyst switches in hybrid network environments.
