What is Security Operations Center?
A security operations center (SOC) is the team, and the set of procedures behind it, responsible for monitoring an organization's systems continuously, investigating security alerts, and coordinating the response when an incident is confirmed. The term describes a function rather than a room. A SOC can be a staffed facility inside a large enterprise, or a service a smaller business subscribes to, in which case it is often called SOC-as-a-service or managed SOC.
Day to day, a SOC receives alerts from detection tools such as endpoint detection and response, Microsoft Defender XDR, a SIEM, email security and firewalls. Analysts triage each alert: is it a false positive, a policy violation, or an active intrusion? Confirmed incidents are escalated according to a severity scale, and responders take containment steps, isolating devices, disabling accounts, blocking indicators and revoking sessions, while keeping a record of what was done. A mature SOC also does proactive work, hunting through logs for signs that automated rules missed and tuning detections to reduce noise.
For a small or mid-sized business, the relevant point is that the tools generate alerts around the clock, and the alerts only matter if someone qualified is reading them. Hiring analysts for three shifts is out of reach for most companies with fewer than a few hundred employees, so the SOC function is bought as a service. When evaluating one, ask who is watching overnight and what actions they are authorized to take without calling you first.
NetSys provides SOC monitoring as part of its managed cybersecurity services, with 24/7 coverage by NetSys engineers rather than a separate outsourced desk. The engineers who monitor are the same engineers who respond, and the client already knows them by name. Every client also has a dedicated account manager reachable by cell phone when an incident needs a decision.
Why it matters for a small business
Attacks against small businesses tend to start on a Friday evening or over a holiday, when nobody is checking the security console. A SOC is the answer to the question of who is watching at that hour. Buying it as a service gives a company without a security department coverage on all three shifts. It also gives you a written response process, which is what an insurer wants to see and what keeps a bad night from turning into a bad month.
Security Operations Center (SOC): FAQs
What is SOC-as-a-service?
SOC-as-a-service is a subscription in which an outside provider supplies the analysts, the monitoring platform and the response procedures of a security operations center for a monthly fee. The provider connects to the customer's detection tools, watches the alert queue continuously, investigates and escalates by an agreed severity scale, and either takes containment actions directly or calls the customer's designated contact. It is the practical way for a business with no security staff to get 24/7 coverage, and it is what NetSys delivers through its SOC monitoring service.
What is the difference between a SOC and MDR?
MDR is a specific service, focused on detecting and responding to threats on endpoints and identities, usually built on an EDR or XDR platform. A SOC is the broader function that can include MDR along with log management, compliance reporting, vulnerability tracking and threat hunting across everything the business runs. In practice the two overlap heavily for small businesses, and many providers use the terms interchangeably. What matters more than the label is whether people are watching around the clock and what they are allowed to do.
How much does a SOC cost for a small business?
SOC services are usually priced per user or per device each month, and the figure depends on how many log sources are connected, how much retention is included and whether response actions are part of the package or billed separately. Ask for the price of the full service, including the incident hours, rather than the monitoring alone. NetSys includes 24/7 monitoring in its month-to-month managed agreements rather than pricing it as a separate line item, and it does not publish pricing without first scoping the environment.
