Cybersecurity teams overwhelmed by alerts, critical infrastructure left unmonitored and budgets drained without results: these are some of the consequences of security operations centre (SOC) deployment mistakes. This step-by-step guide from Kaspersky is designed to help you avoid the pitfalls and build an effective SOC.

When to build a SOC

Businesses are distinct entities that navigate unique challenges. There are, however, common triggers that set the SOC-creation process in motion. Some are logical and proactive:

Regulatory requirements, especially in critical infrastructure;
Proactive risk awareness – understanding that a cyberattack can interrupt the business; and
An observed increase in cyberthreats – facing more frequent or more sophisticated attacks that require a dedicated team to mitigate.

Other triggers are reactive and therefore less desirable. A business that has already been attacked realises it lacks the capability to respond effectively. It starts its SOC journey from a position of financial insecurity, while fighting to undo reputational damage.

Core competencies required from day one

Once an organisation has established that it needs a SOC and can afford one, it must work out early what the SOC needs in order to function, and build foundations it can scale from. At the top of the list is human capability. Every SOC rests on three core roles:

Security analysts (investigation, triage and response) – frontline defenders who triage alerts, investigate suspicious activity and perform initial response. They separate false positives from real threats and ensure swift, effective incident handling.
Engineers (technical maintenance and support) – responsible for deploying, maintaining and optimising security tools and infrastructure.
Threat researchers (modern threat awareness, detection development) – focused on identifying emerging threats and developing detection strategies. They analyse threat intelligence, create detection rules and help the SOC stay ahead of evolving tactics.

Between them, these roles cover operations, technical maintenance and development for threat protection. Each requires expertise a fledgling SOC will fail without.

The cybersecurity skills gap makes staffing a SOC harder, so factor substantial time and budget into sourcing talent.

Headcount matters too, because a SOC requires round-the-clock coverage. A foundational team runs to at least 10 people: a manager, five analysts, two engineers and two researchers. Small teams quickly face unsustainable workloads and alert fatigue, and many of those alerts will be false positives. That leads to burnout, which in turn raises the odds of a missed threat.

An organisation that cannot staff a SOC properly is better off appointing an external provider to monitor threats on its behalf. Managed security service providers (MSSPs) can deliver monitoring and incident response matched to the organisation’s industry, capability and budget.

For a business that is ready to build, the focus shifts to scalability. Core systems – telemetry pipelines, correlation engines and the rest – need to scale horizontally. Anticipate architectural limits early so you are prepared for growth and can account for future costs such as disaster recovery.

Processes you must establish to ensure value

A successful SOC deploys not only people and technology but processes, and there is an order in which they should come.

Asset inventory: Many SOCs do not understand what they are protecting. Inventory work may look like an IT task, but you cannot secure what you have not catalogued.
Threat monitoring: Work out how you acquire telemetry, detect signs of threats and then manage those threats.
Mature operations: Move on to threat hunting, research and continuous detection engineering. Growing human expertise becomes a priority, alongside defined processes, metrics, investment in SOC infrastructure resilience and continuous improvement.

There are shortcuts to SOC functionality. One is to draw on third-party knowledge in the form of frameworks, which act as a blueprint and can accelerate the design process.

“First-time SOCs often rely too heavily on technology and default vendor content, assuming that tools will function effectively without tuning or skilled operators. Expecting instant results from out-of-the-box solutions leads to missed threats and false confidence. Another common pitfall is neglecting continuous improvement – treating the SOC as static rather than an evolving capability, which prevents adaptation to new attack techniques,” says Roman Nazarov, head of SOC consulting at Kaspersky.

Preparing for and measuring SOC success

A SOC must deliver value early. Prepare with clear objectives, defined playbooks and the right people, processes and technology. Prove readiness through rigorous testing: red-team exercises validate detection at every stage of an attack, and attack simulations confirm coverage. These expose gaps – and let you close them – before a real incident does it for you.

Measure success using mean time to detect (MTTD) and mean time to respond (MTTR). A falling MTTD shows faster threat discovery; a lower MTTR proves quicker containment and remediation. Constant testing and metric tracking will keep the SOC improving from day one.

Key takeaways

A successful SOC starts with a core team of analysts, engineers and researchers. Frameworks can accelerate setup, but tuning and customisation are essential. Start with asset inventory, an understanding of likely attack vectors and basic monitoring before implementing advanced processes. MSSPs and consultants can support early operations, bridge skills gaps and provide ongoing expertise. Plan for scalability from day one, in technology and in budget. Above all, people are critical: without sufficient human capacity and expertise, even the best tools and frameworks will not prevent a SOC from failing.
