OS

How it works

• Windows, macOS, iOS, Android and Linux are operating systems.
• Makers stop updating old versions on a set date (end of support).
• After that date, new holes stay open for good.
• Keep every device on a supported version.

What can go wrong (example scenario)

A three-person dental lab ran a milling machine on an old Windows 7 PC because “it still works”. That PC was on the same network as everything else. A worm that Windows 7 could never be patched against spread from it to the office computers.

How WILDCARD handles it

Patch Management keeps Windows, Office and Chrome updated on every covered computer. Devices running an operating system past end of support get flagged, because there is nothing left to patch.

• A dental office has two front-desk PCs still on Windows 10 after support ended.
• A law firm's partner uses a MacBook three macOS versions behind and skips every update prompt.
• A retailer's point-of-sale terminal runs an embedded OS the vendor stopped updating.

Example scenario: A small accounting firm had one old laptop in the back for scanning. It ran an unsupported Windows version and was never updated. A staff member used it to check email once, clicked a link, and the machine became the entry point for an intruder who then reached the main server.

A question owners ask

My computer still works fine. Why does the OS version matter?

Working and safe are different things. Once the maker stops releasing fixes, every new flaw stays open, and attackers specifically scan for those versions.
