Patch tools differ in their third-party app coverage, whether they are managed from the cloud or on premises, and their reporting. Compare how well they handle remote devices and how quickly you can push critical patches.
Why it works
Auditors require a patch policy and evidence that you follow it. Patching internet-facing systems matters most, and that part is covered under external vulnerability management.
What to look for
It should patch third-party applications, not just the operating system.
