Quick Answer 

A Security Operations Center is a team of analysts watching your systems around the clock. SOC monitoring is that team reviewing security events as they happen, investigating what looks wrong, and escalating or containing genuine threats.

How It Works

Logs and alerts from your endpoints, network, cloud services, and email flow into a SIEM platform, which correlates them and surfaces anomalies. Analysts triage what it produces — most alerts are benign, and separating those from real attacks is the bulk of the work. Confirmed threats get contained or escalated, depending on what the service covers.

Most Businesses Don't Build Their Own

Running a SOC in-house means round-the-clock staffing — realistically several analysts across shifts, plus the platform. That's out of reach for most businesses under a few thousand staff.

The usual route is a shared SOC, where analysts monitor many organisations from one facility. You get overnight coverage without the headcount, at the cost of a team that doesn't know your environment as intimately as internal staff would.

SOC vs. MDR

A SOC is where the analysts sit. MDR is the service you buy that includes them. If you're evaluating providers rather than building capability, MDR is the term you want

What to Ask a Provider

Whether coverage is genuinely 24/7 or business hours with on-call. What they can contain without waiting for your approval. How quickly they escalate. And what data sources they monitor — a SOC watching only endpoints will miss identity attacks in Microsoft 365.

Example Scenario 

A 175-person healthcare organisation wanted detection outside working hours. PureStack implemented SOC monitoring integrated with its SIEM, EDR, Microsoft 365, and firewalls. One weekend the SOC spotted unusual sign-in activity followed by attempts to reach patient records, investigated immediately, and isolated the account before the attacker went further.
