[QUOTE="Andy Ful, post: 958688, member: 32260"] If I correctly recall the updates for home users are not as frequent as for Enterprises. Some time ago I noticed 3 or 4 updates a day (no more). Many computers in Enterprises are not connected to the Internet but can download updates from the local server. Frequent updates can have some value for them. But, such an environment is very different from the home environment or mobile user environment. I am afraid that this is pretty much an illusion because the protection without an Internet connection is not very good even after the update. In such cases, one cannot rely on Defender alone. The fast threat response updates are not available without an Internet connection. Anyway, most ASR rules work as advanced HIPS and do not require frequent updates and Internet connection. There are also exceptions: [LIST] [*][URL='https://docs.microsoft.com/en-us/microsoft-365/security/defender-endpoint/attack-surface-reduction-rules?view=o365-worldwide#block-executable-files-from-running-unless-they-meet-a-prevalence-age-or-trusted-list-criterion']Block executable files from running unless they meet a prevalence, age, or trusted list criterion[/URL] [*][URL='https://docs.microsoft.com/en-us/microsoft-365/security/defender-endpoint/attack-surface-reduction-rules?view=o365-worldwide#use-advanced-protection-against-ransomware']Use advanced protection against ransomware[/URL] [/LIST] These ASR rules require an Internet connection. The AV testing labs always make an update just before testing Defender. So, the offline results can reflect the situation when the user has set Defender to update most frequently. Still the results are not great when offline. If the malware samples were executed from the USB drive with ASR rules enabled then the results would be probably much better. But this would not follow from the frequent updates. (y):coffee: [/QUOTE]
