EDR, MDR, SOC: Security Monitoring Explained for SMBs

Antivirus, EDR, MDR, SOC: these acronyms look alike but do very different things. Here is what your SMB actually needs, without the jargon.

EDR, MDR, SOC: Security Monitoring Explained for SMBs

An expensive alphabet soup

When it comes to protecting a business, you get bombarded with acronyms: EDR, MDR, XDR, SOC. Every vendor pushes their own, and it becomes hard to know what you are actually buying. Here is a plain explanation.

Antivirus: the front door, not the summit

Traditional antivirus compares files against a list of known threats. Useful, but outmatched by modern attacks that use no recognizable file. It is the minimum, not the protection.

EDR: the security camera for your devices

EDR, endpoint detection and response, continuously monitors the behavior of your computers and servers. Instead of looking for a known file, it spots a suspicious action, such as a process trying to encrypt thousands of files. It can isolate the affected device automatically.

The catch: EDR generates alerts. Without someone to analyze them, they go nowhere.

MDR: EDR plus experts on watch

MDR, managed detection and response, adds the human element. A team of specialists watches your alerts around the clock, sorts the real from the false and steps in when needed. For an SMB with no in-house security team, this is often the most sensible option: the technology and the eyes watching it.

SOC: the nerve center

A SOC, security operations center, is the team and infrastructure that provide that monitoring, often 24 hours a day. You do not need to build your own, which would cost a fortune. You can access one through a partner.

What your SMB actually needs

  • The bare minimum: a modern EDR on every device.

  • The right balance for most SMBs: an MDR service that monitors and responds on your behalf.

  • The reflex to keep: paying for a tool with no monitoring is like installing an alarm no one listens to.
  • Not sure where you stand? Let's discuss your current level of protection and what would have the most impact.
