How we check

Support dates come from endoflife.date, which tracks vendors' published lifecycle dates. The 14-day rule comes from the NCSC's Cyber Essentials requirements for IT infrastructure (v3.3): software in scope must be supported, and high-risk or critical security updates must be installed within 14 days of release. Always confirm on the device itself. This tool is a guide, not an assessment.

Guidance only. Please read before using this tool. Our tools are free, general guidance to help you prepare. They are not an assessment, a pre-check, or advice on your organisation, and a result here does not mean you will pass Cyber Essentials. The tools help you check parts of your setup, but they don’t do everything for you: they can’t put policies, processes and procedures in place, or show how your controls meet each requirement. The NCSC requirements and IASME’s marking guidance change frequently, and our tools are not updated in line with every change, so they may be incomplete, out of date or wrong. Your organisation is responsible for its own answers, for its controls, and for checking them against the current requirements. Only the assessor who marks your submission decides whether it passes. As far as the law allows, Get Cyber Certified accepts no liability for any loss, failed assessment or other outcome arising from using these tools. By using this tool you agree to our free tools terms.
