Managed Detection and Response
Detection without response is just a record of how you were breached.
Most small businesses already generate security alerts. What they lack is anyone to read them at two in the morning, decide which of them matters, and isolate a machine before the intrusion spreads.
Traditional antivirus
Matches files against known signatures and quarantines what it recognizes. Effective against commodity malware, and blind to an attacker who signs in with valid credentials bought from a broker, uses the administrative tools already installed, and never drops a file worth scanning.
Managed detection and response
Watches behavior rather than files. A valid account reading every share in sequence, or a process spawning where it never has before, is a pattern no signature covers. Analysts investigate the pattern, decide whether it is an attack, and contain it.
What happens when something fires
01
Detect
Behavioral telemetry raises an anomaly: an unusual sign-in, a privilege change, mass file access, a process acting out of character.
02
Investigate
An analyst establishes whether it is genuine, how it started, and what else the same actor has touched.
03
Contain
The device is isolated or the account disabled within minutes, cutting off spread while the full scope is still being worked out.
04
Report
You get what happened, what was reached, what was done about it, and what needs changing so it does not recur.
Who is watching your systems tonight?
If nobody is reading the alerts outside business hours, the gap is worth understanding before something uses it.
