The Cybersecurity Timebomb: Major Security Appliances Reaching EOL in 2025 & 2026
Published by the Information Security Team • Reading Time: 5 mins
In the realm of Information Security, running End of Support (EOS) or End of Life (EOL) hardware and software isn't just an operational headache—it is a critical security vulnerability. Threat actors actively exploit legacy Firewalls, IPS, WAFs, Load Balancers, and Endpoint agents that no longer receive vendor vulnerability patches.
If your network relies on older Fortinet E-Series, outdated Palo Alto PAN-OS versions, Cisco ASAs, or Gen 6 SonicWall appliances, the time to finalize your hardware refresh and cloud migration budget is now. We have compiled an OEM-specific matrix for major IT Security products reaching their final days in 2025 and 2026.
2025 EOS / EOL Matrix
These products will stop receiving security updates, software patches, or hardware replacement support this year. Immediate migration is strictly advised.

2026 EOS / EOL Matrix
Budgeting and architectural planning for these appliances and platforms should begin immediately to ensure a smooth, compliant transition next year.
| Sr. No | Product Name | Product Version | OEM Name | End of Support Date | End of Life Date |
|---|---|---|---|---|---|
| 1 | FortiGate 60E / 61E | Hardware | Fortinet | March 2024 (Eng.) | March 2026 |
| 2 | FortiGate 100E / 101E | Hardware | Fortinet | March 2024 (Eng.) | March 2026 |
