Scanning, mitigation and patch-around guidance for Fedora Linux 23 when the vendor no longer ships fixes.
Compliance Maintenance
Procedure review, controls evidence and the documentation auditors ask for — maintained continuously, not scrambled at audit time.
24/7 Expert Support
Engineers who know this release monitor, manage and fix issues around the clock — break/fix to managed operations.
Fedora Linux 23 Support: Frequently Asked Questions
Is the Fedora Linux 23 still supported?
Fedora ended support for the Fedora Linux 23 on Dec 20, 2016 — no more patches or fixes from the vendor. Third-party support keeps it covered: our engineers manage issues, remediate vulnerabilities, and help you maintain compliance for as long as you run it.
When is the Fedora Linux 23 end of service life (EOSL) date?
Fedora lists the end of service life for the Fedora Linux 23 as Dec 20, 2016.
Can I keep using the Fedora Linux 23 after its EOSL date?
Yes. EOSL means Fedora stops issuing patches and support — the software itself keeps running. Third-party support covers it from there: issue management, security vulnerability remediation, and the compliance documentation auditors ask for, for as long as you choose to run it.
How much does third-party support for the Fedora Linux 23 cost?
Typically 40-70% below the OEM maintenance renewal price. Exact pricing depends on quantity, service level and location — request a quote and we respond within 24 hours.
