Basic antivirus catches yesterday's threats. Modern attacks — ransomware, fileless malware, zero-days — walk right past it. Your business computers need endpoint detection that actually fights back.
Standard antivirus matches known threats against a signature list. Defender watches behavior — what a program is actually doing — which is how it catches ransomware and zero-days that have never been seen before.
The affected device gets automatically isolated from your network and rolled back to before the attack — instead of spreading to every other connected device.
Yes — Windows, macOS, and Linux are all covered the same way, same price, same response. If your team is mixed, nothing is left out.
No — this replaces it, it doesn't sit next to it. Signature-based antivirus alone now misses a large and growing share of attacks, since fileless malware never writes a file to disk for a signature scanner to catch. Behavior-based detection is what catches what signature-matching can't.
We are — not you, and not nobody. A detection tool is only as good as the person responding to what it flags; an unwatched alert at 2am does nothing for you. That monitoring is the actual managed part of this, not just the software.
