Antivirus vs. EDR: the difference that matters
Traditional antivirus is a gate: a known-bad file arrives, the gate blocks it, end of story. EDR — endpoint detection and response — is a gate plus a guard with a radio. It watches behavior on every operating system: on Windows through Defender, on Linux through ClamAV plus auditd, on macOS through an Endpoint Security extension — what processes launch, what they touch, where they came from. It flags what's suspicious even when no signature matches, and it hands you response tools — cut the device off the network, terminate the process, lock the file away.
For an SMB the practical difference shows up in the first real incident: antivirus leaves you with a log line; EDR leaves you in control.
What 'response' actually means
Four actions cover most incidents. Isolation blocks all network traffic from a device except the security platform itself — the machine can't spread anything or reach an attacker, but you can still investigate and restore it remotely. Kill terminates a malicious process and its children. Quarantine moves a file into an encrypted store so it can't execute — done right, the file never leaves the machine. And when a device is lost or stolen rather than merely infected, remote wipe erases it — cryptographically, in seconds, on an encrypted disk — so the data can't be recovered.
Speed is the whole game: a response that lands in a minute contains an incident; one that waits for a technician's next visit doesn't.
Why AI triage changes who can run EDR
The historical reason SMBs skipped EDR: every detection needed an analyst to read it. Modern platforms put AI in that seat — each detection arrives already triaged, with a plain-English verdict: what this is, how serious it is, whether the engine already contained it, and the one next step to take.
That turns EDR from a tool that requires a security hire into one an IT generalist — or an owner — can act on with confidence.
What it should cost, and what to protect
You don't need EDR on every machine — you need it on the ones that matter: domain controllers, file servers, finance and executive laptops, anything holding customer data. Per-endpoint pricing in the $4–6/device range makes that a sub-$100 decision for most SMBs.
Cybermatic Endpoint Protection runs on the same agent as posture management: install everywhere, flip protection on per device from the portal, and each protected endpoint gets AI-triaged detection with one-click response. Plans start at $29/month with a 14-day trial.
