Palo Alto's End-of-Sale and End-of-Life dates are shown as end of sale and last date of support. Last supported software: PAN-OS 11.1. PAN-OS 11.1 stays in extended support on this model until the hardware end of life. Dates also apply to the PA-850-ZTP.
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
Palo Alto Networks' named successor: PA-1400 Series (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 PA-850 still safe to use?
Palo Alto Networks still supports the PA-850, so it can still receive security fixes, but it is no longer sold. Plan a replacement before support ends.
What replaced the PA-850?
Palo Alto Networks' own bulletin names the PA-1400 Series as the replacement. The right choice still depends on your sites, users and licensing.
