A Security Operations Centre (SOC) is a dedicated team, function or outsourced service that monitors an organisation’s IT environment for cyber threats. A SOC collects security data from systems, users, endpoints, cloud platforms and networks, then analyses that activity to detect, investigate and respond to potential attacks.
The main purpose of a SOC is to identify threats quickly, reduce the impact of incidents and give businesses continuous visibility across their security environment.
What does a Security Operations Centre do?
A Security Operations Centre monitors, detects, investigates and responds to security activity across a business’s IT environment. It acts as the centre of a company’s cyber defence strategy, using security tools and skilled analysts to identify suspicious behaviour and mitigate threats in real time.
The main responsibilities of a SOC include:
- Monitoring security alerts: reviewing activity from networks, endpoints, cloud platforms, users and security tools.
- Detecting threats: identifying suspicious behaviour, attempted breaches, malware activity and signs of compromise.
- Investigating incidents: analysing alerts to understand what happened, which systems are affected and how serious the threat is.
- Coordinating response: escalating incidents, containing threats and guiding remediation activity.
- Improving defences: using lessons from incidents, threat intelligence and reporting to strengthen the organisation’s security posture.
A 24/7 SOC is important because cybercriminals do not operate on a fixed schedule. Round-the-clock monitoring helps businesses identify suspicious activity, escalate real incidents and reduce the potential impact of security breaches.

Key components of a Security Operations Centre
A SOC relies on people, processes and technology working together. Each component plays a different role in monitoring threats, investigating incidents and improving security resilience.
| SOC component | What it includes | Why it matters |
|---|---|---|
| People | Security analysts, threat hunters, incident responders and SOC managers. | Human expertise is needed to interpret alerts, investigate threats and make response decisions. |
| Processes and procedures | Incident response plans, escalation routes, triage workflows, communication protocols and reporting procedures. | Clear processes help the SOC respond consistently and quickly when threats appear. |
| Technology | SIEM, EDR, IDS/IPS, threat intelligence, XDR, SOAR and cloud security tools. | Security tools collect, correlate and prioritise activity so analysts can focus on genuine risks. |
Common SOC tools
SOC teams use a range of technologies to collect security data, detect suspicious activity and support investigation. The exact stack varies by organisation, but common SOC tools include:
- SIEM systems: collect and correlate logs from networks, servers, applications and security tools to identify suspicious patterns.
- IDS/IPS tools: monitor network traffic for suspicious activity and, in some cases, block threats before they spread.
- EDR tools: monitor laptops, desktops, servers and mobile devices for endpoint-level threats.
- Threat intelligence platforms: help SOC teams understand emerging threats, attacker techniques and known indicators of compromise.
- XDR and SOAR tools: connect data across multiple security platforms and support faster investigation, escalation and response.
How does a Security Operations Centre work?
A Security Operations Centre follows a structured process for identifying, investigating and responding to cyber threats. The exact workflow varies by organisation, but most SOC teams follow the same core stages.
- Collect security data: logs and alerts are gathered from endpoints, networks, cloud platforms, identity systems and security tools.
- Monitor and triage alerts: analysts review security activity and separate false positives from genuine risks.
- Investigate suspicious activity: the SOC assesses affected systems, user behaviour, attack indicators and potential business impact.
- Contain threats: compromised accounts, devices or systems are isolated where needed to stop the threat spreading.
- Remediate and recover: the organisation removes the threat, fixes weaknesses and restores normal operations.
- Report and improve: the SOC documents what happened and uses the findings to improve future detection, response and security controls.
Key roles in a SOC team
A SOC is usually made up of several specialist roles. Smaller organisations can access these roles through an outsourced SOC provider, while larger organisations may hire them internally.
- SOC analysts: monitor alerts, investigate suspicious activity and triage potential incidents.
- Incident responders: help contain threats, coordinate remediation and support recovery after a security incident.
- Threat hunters: proactively search for hidden threats that automated tools may not detect.
- Security engineers: configure, maintain and improve the security tools used by the SOC.
- SOC managers: oversee the operation, reporting, escalation processes and overall service performance.
Types of Security Operations Centres
Not every SOC is built in the same way. The right model depends on your organisation’s size, budget, internal expertise and need for continuous monitoring.
| SOC type | What it means | Best for |
|---|---|---|
| In-house SOC | A SOC built and operated internally by your own security team. | Larger organisations with mature security teams, bigger budgets and complex environments. |
| Outsourced SOC | A SOC delivered by an external managed security provider. | SMEs and mid-market organisations that need specialist monitoring and response without building a full internal team. |
| Hybrid SOC | A shared model where internal teams handle some security operations and an external provider supports specific areas or out-of-hours coverage. | Organisations with some internal capability that need extra expertise, capacity or 24/7 coverage. |
Benefits of a 24/7 Security Operations Centre
A 24/7 Security Operations Centre gives businesses continuous protection against cyber threats. Instead of relying on reactive support after something goes wrong, a SOC provides ongoing monitoring, investigation and response capability.
1. Round-the-clock monitoring
Cyber threats can happen at any time. A 24/7 SOC gives your organisation continuous visibility across systems, users, endpoints, cloud platforms and networks. This reduces the risk of suspicious activity going unnoticed outside normal working hours.
2. Faster threat detection and response
A SOC helps identify threats earlier by monitoring alerts, reviewing suspicious behaviour and escalating genuine incidents quickly. Faster detection gives your business more time to contain issues before they cause disruption.
3. Better visibility across your environment
Many organisations struggle to understand what is happening across their IT estate. A SOC brings security data together from different systems, giving your business a clearer view of risks, incidents and trends.
4. Access to specialist security expertise
Building an internal security team can be expensive and difficult. A SOC gives your business access to experienced analysts, incident responders and security specialists without needing to recruit and retain a full team internally.
5. Stronger reporting and continuous improvement
A SOC does more than respond to alerts. It also provides reporting, trend analysis and recommendations that help improve your security posture over time. This supports better decision-making, compliance and board-level visibility.
In-house vs outsourced Security Operations Centre
Businesses can either build an internal SOC or use an outsourced SOC provider. The right option depends on budget, internal expertise, risk level and the need for 24/7 coverage.
| Option | Best for | Things to consider |
|---|---|---|
| In-house SOC | Larger organisations with mature security teams, bigger budgets and complex environments. | Requires hiring analysts, buying tools, maintaining processes and providing continuous training. |
| Outsourced SOC | SMEs and mid-market organisations that need specialist monitoring and response without building a full internal team. | Provides faster access to expertise, established processes and 24/7 monitoring capability. |
For many small and mid-sized businesses, an outsourced SOC is the more practical option. It gives access to security expertise, monitoring tools and defined response processes without the cost and complexity of building a full in-house operation.
