A SOC (Security Operations Center) is a specialized team, internal or external, that monitors, detects, analyzes, and responds to cybersecurity threats continuously, combining people, processes, and technology to protect an organization's digital infrastructure around the clock.
How does a SOC work?
A SOC collects and correlates data from across the entire technology infrastructure (networks, servers, endpoints, applications, and the cloud) using tools such as SIEM and EDR. Certified analysts review the alerts generated, rule out false positives, and activate response protocols when they confirm a real threat. The goal is to reduce the time between detecting an incident (MTTD) and containing it (MTTR).
SOC vs. MDR: what is the difference?
A SOC is the broad concept: the organizational function of continuous monitoring. MDR (Managed Detection and Response) is a service model managed by a third party that delivers that function as a subscription service, generally with an additional focus on active response and not just detection. In practice, most companies that ask “do we need a SOC?” are actually looking for an MDR service, since building and operating an in-house 24/7 SOC requires between 8 and 12 analysts in rotating shifts, plus enterprise tools.
When does your company need a SOC?
- You handle sensitive customer data, payments, or regulated information.
- You must comply with regulations such as ISO 27001, PCI DSS, or GDPR.
- You do not have continuous (24/7) visibility into what happens on your network.
- You have already suffered a security incident or detected suspicious activity.
- Your current IT team has no dedicated capacity for threat monitoring.
Frequently asked questions
Does a SOC replace the in-house IT team?
No. A SOC focuses specifically on monitoring, detecting, and responding to cybersecurity threats. The in-house IT team continues to manage infrastructure, support, and technology projects; the two usually work in coordination.
How much does it cost to operate a SOC?
Building an in-house 24/7 SOC can cost millions of pesos a year in staff, tools, and licenses. A managed SOC (MDR/MSSP) spreads that cost across several clients and usually turns out 60-70% less expensive for equivalent capability.
What is the difference between a SOC and a SIEM?
A SIEM is a software tool that collects and correlates security records (logs). The SOC is the human team and the process that uses that tool, along with others, to monitor, investigate, and respond to threats.
Can I have a SOC without hiring an MSSP?
Yes, it is possible to build an in-house SOC, but it requires considerable investment in certified staff, rotating shifts, and tools. That is why most mid-size companies opt for an externally managed SOC.
