What this means for your business
- Security patches should continue until support ends, but spares and new licences may get harder to buy.
- Cyber insurance questionnaires increasingly ask whether any equipment is unsupported or past end of life.
- Planning early avoids an emergency swap at the end of support.
- This is general information, not legal or insurance advice.
Replacement options
Vendor-neutral options to consider:
- Palo Alto Networks PA-400 series
- Ubiquiti UniFi Cloud Gateway
- MikroTik RouterOS appliances
The right replacement depends on your sites, users and licensing, and is often cheaper than a like-for-like swap.
Keep or replace? Quick checklist
- Is it your internet-facing firewall?
- Do you have remote staff connecting through it?
- Is your cyber insurance renewal in the next 6 months?
- Do you store client or financial data behind it?
- Is it running old firmware, or does it have no active vendor licence?
Two or more “yes” answers on an unsupported or soon-to-be-unsupported device is a good reason to get advice.
Frequently asked questions
Is the FortiGate 400E still safe to use?
