Sophos terms mapped: End-of-Sale (EOS) = end of sale; End-of-Life (EOL) = date support ceases and RMAs are no longer processed = last date of support. Last 1-year renewal was 2024-03-31. Sophos lists no separate software maintenance or vulnerability support dates for this model.
What this means for your business
- No new security patches: newly found vulnerabilities stay open on an internet-facing device.
- Cyber insurance questionnaires increasingly ask whether any equipment is unsupported or past end of life.
- No vendor support for faults, so a failure can mean days without a working firewall.
- This is general information, not legal or insurance advice.
Replacement options
Sophos' named successor: XGS 3300 (migration path) (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 XG 330 still safe to use?
Not for a business network. Sophos no longer issues security fixes for the XG 330, so new vulnerabilities will not be patched.
What replaced the XG 330?
Sophos' own bulletin names the XGS 3300 (migration path) as the replacement. The right choice still depends on your sites, users and licensing.
Where do these dates come from?
From Sophos' own lifecycle bulletins. Each date in the table links to its source, with the date we last checked it. Always confirm with Sophos before making decisions.
