WatchGuard lists only End of Sale and End of Life. End of Life is recorded here as last date of support; WatchGuard does not publish separate software maintenance or vulnerability support dates on this page.
What this means for your business
- Security patches stop when support ends, so the exposure starts on that date.
- Cyber insurance questionnaires increasingly ask whether any equipment is unsupported or past end of life.
- Vendor support for faults ends at the same time.
- This is general information, not legal or insurance advice.
Replacement options
WatchGuard's named successor: Firebox T115-W (source).
Vendor-neutral options to consider:
- Fortinet FortiGate (entry range)
- 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 Firebox T15 still safe to use?
For now, yes, but support ends soon. After that date WatchGuard stops issuing security fixes, so plan a replacement before then.
What replaced the Firebox T15?
WatchGuard's own bulletin names the Firebox T115-W as the replacement. The right choice still depends on your sites, users and licensing.
Where do these dates come from?
