What is a Security Operations Center (SOC), and does your business need one?
What a SOC does every day, how a managed SOC compares with building your own, and the signs your organisation needs 24×7 monitoring.
Updated October 2026 · 6 min read
Data is now one of the most valuable things an organisation owns, and attackers know it. Firewalls and antivirus stop many threats, but they cannot tell you when someone is quietly moving through your network, or respond when an alert fires in the middle of the night. That is the job of a Security Operations Center.
What is a Security Operations Center?
A Security Operations Center (SOC) is a team, supported by processes and technology, that monitors an organisation's systems, detects cybersecurity threats and responds to incidents. Its purpose is to protect your digital assets, information and systems continuously, not only during office hours.
What does a SOC actually do?
- Monitor: collect and watch security logs from servers, endpoints, cloud services, email and network devices.
- Detect: correlate events to spot suspicious activity, from phishing and malware to unusual sign-ins.
- Investigate: confirm what happened, which systems are affected and how serious it is.
- Respond: contain the threat, for example by isolating a device or disabling a compromised account, and guide recovery.
- Improve: report on trends and tune defences so the same attack does not succeed twice.
In-house SOC or managed SOC?
Large enterprises sometimes build their own SOC. Most organisations find a managed SOC more practical, because the hardest part is staffing it around the clock.
| In-house SOC | Managed SOC | |
|---|---|---|
| Coverage | Depends on how many shifts you can staff | 24×7 from day one |
| People | Hire, train and retain specialist analysts | Provided by the partner |
| Tooling | Buy and run SIEM and response tools yourself | Included in the service |
| Time to start | Months to design and build | Onboarding in stages, critical systems first |
| Control | Full internal control | Shared, with clear SLAs and reporting |
Signs your organisation needs a SOC
- You hold customer, financial or health data that would be costly to lose.
- Regulators, auditors, insurers or enterprise customers ask how you monitor for threats.
- Your IT team is stretched and security alerts go unreviewed.
- Nobody would notice an attack that started outside office hours.

Frequently asked questions
What is the difference between a SOC and a SIEM?
A SIEM is a tool that collects and correlates security logs. A SOC is the team and processes that use tools like a SIEM to monitor, investigate and respond to threats around the clock.
Do small and mid-sized businesses need a SOC?
Most do not need to build one, but they do need SOC-level monitoring. A managed SOC gives smaller organisations 24×7 detection and response without hiring and training an in-house team.
How long does it take to set up a managed SOC?
It depends on the size of your environment and the log sources involved. Onboarding typically starts with your most critical systems first, so monitoring begins early and expands from there.
What is a SOC maturity assessment?
A structured review of how well your security operations perform today, measured against a maturity model such as CMMI, with a prioritised plan to improve.
