What does PAN-OS 2.0 end of life mean?
When PAN-OS 2.0 reaches end of life, the maintainers stop issuing security patches for this version. CVEs discovered after the EOL date are publicly disclosed on the National Vulnerability Database with no patch available. Exploit code frequently appears on GitHub within days of disclosure.
The CVE blind spot: A CVE-based scan does not show the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Some scanners flag unsupported versions of common products, but coverage varies, and none of them give you the date in advance. Running PAN-OS 2.0 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to PAN-OS 12.2 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.

What are the security risks of running PAN-OS 2.0 past EOL?
When PAN-OS 2.0 reaches end of life, the maintainers stop issuing security patches. Any CVEs disclosed after the EOL date accumulate with no vendor fix. A CVE-based scan does not show this — it is the CVE blind spot; some scanners flag unsupported versions of common products, but coverage varies and none give the date in advance. Organizations running EOL PAN-OS should migrate immediately or implement compensating controls.
