Building a 24/7 Security Operations Centre: In-House vs Managed

A 24/7 security operations centre is the capability to detect, investigate and respond to cyber threats at any hour of any day. For most large organisations the question is no longer whether they need one, but whether to build it in-house or obtain it from a managed provider. That decision has real financial weight: IBM’s 2026 Cost of a Data Breach Report found the average breach now takes 247 days to identify and contain, and that breaches with a lifecycle under 200 days cost materially less than those that ran longer (IBM, via SecureWorld). Continuous coverage is not a luxury. It is one of the clearest levers an organisation has on the cost of an incident.

Why 24/7 coverage is the baseline now

Attackers deliberately operate outside business hours. An intrusion that begins at 2am on a public holiday is one that a nine to five security team will not see until the estate has already been mapped and data staged for exfiltration. As agentic and automated attacks compress the time between initial access and material impact, the window in which a human needs to notice and respond keeps shrinking.

The economics follow directly. When detection and containment are faster, the blast radius is smaller, recovery is cheaper, and regulatory and reputational exposure is lower. This is why the breach lifecycle number matters so much: every day shaved off detection and response is money not lost. A SOC that goes dark at close of business is, in effect, choosing a longer lifecycle.

The case for an in-house SOC

Building your own SOC gives you the most direct control. Your analysts know your environment intimately, escalation paths are internal, and highly sensitive data never leaves your boundary. For a very large organisation, or one in defence, intelligence or critical national infrastructure, that control can be decisive.

The difficulty is sustaining it. A genuine 24/7 capability is not one team, it is several, rostered to cover nights, weekends and holidays without burning out. It requires:

• Enough skilled analysts to staff every shift, in a market where security talent is scarce and expensive, plus cover for leave and attrition.
• A significant tooling investment, including SIEM, SOAR, threat intelligence feeds and the engineering to keep them tuned.
• Mature processes and continuous training, so that response quality does not drop at 3am.

Few organisations can stand this up quickly, and many that try end up with daytime depth and thin overnight cover, which is precisely when it matters most.

The case for a managed SOC

A managed SOC, delivered by a specialist provider, gives an organisation round the clock coverage far faster and usually at lower and more predictable cost. The provider spreads the cost of senior analysts, tooling and threat intelligence across many clients, so each one gets a level of capability that would be uneconomic to build alone. Maturity that would take years to develop in-house is available from day one.

The honest question is not “can we build a SOC?” but “can we run one, well, at three in the morning, every night, for years?” For most organisations the answer points to managed or hybrid.

The trade-off is that a managed SOC is only as good as the provider and the integration. The provider needs deep visibility into your environment, clear and fast escalation into your teams, and a genuine understanding of your business context so that alerts are triaged with the right priorities. A poorly integrated managed service produces noise and slow handoffs. A well integrated one operates as a seamless extension of your own team.

The hybrid model most enterprises land on

In practice, many large organisations choose neither extreme. They keep security strategy, governance, risk ownership and the most sensitive response functions in-house, while a managed provider delivers the continuous monitoring, detection and first line triage that is hardest to staff around the clock. This keeps accountability and context internal while solving the coverage problem economically.

The right split depends on your scale, your risk profile, the sensitivity of your data and the maturity of your existing team. The decision should be driven by those factors, not by a preference for building or buying in the abstract.

How to decide

1. Start from your risk and obligations. What threats do you realistically face, and what do regulators, contracts and your board require of you?
2. Be honest about staffing. Can you genuinely recruit and retain enough skilled analysts to cover every shift, indefinitely? If not, in-house 24/7 is aspirational.
3. Compare total cost over several years, including tooling, training and attrition, not just headline salaries.
4. Decide what must stay in-house on control or sensitivity grounds, and what can be delivered by a partner.
5. If using a provider, weight integration heavily. Visibility, escalation speed and business context matter more than any feature list.

Where Jaykan fits

Jaykan runs a 24/7 security operations centre for enterprises and government organisations, combining continuous monitoring, threat intelligence and incident response with the deep integration that makes a managed SOC feel like an extension of your own team. Whether you need a fully managed capability or a hybrid that complements an in-house team, we build the model around your risk and your obligations. You can see the detail of our cyber security services and how we deliver them.

If you want to know how quickly your organisation would currently detect and contain a serious incident, a complimentary, senior led assessment will benchmark your posture and show you where the gaps are.

Frequently asked questions

What is a 24/7 SOC?

A security operations centre is the team, processes and technology that monitor an organisation's systems for threats and respond to them. A 24/7 SOC provides that coverage at all hours, every day, so an attack that begins overnight or on a weekend is detected and acted on immediately rather than the next business day.

Is it cheaper to build or outsource a SOC?

For most organisations a managed SOC reaches full 24/7 capability faster and at lower and more predictable cost than building in-house, because the provider spreads the cost of skilled analysts, tooling and threat intelligence across many clients. Building in-house can make sense at very large scale or where control and data sensitivity demand it.

Why does round the clock coverage matter so much?

Attacks do not wait for business hours, and the longer a breach goes undetected the more it costs. IBM's 2026 research found breaches with a lifecycle under 200 days were substantially cheaper than longer ones, so faster detection and containment directly reduces financial impact.

What is the difference between a SOC and an MSSP?

A SOC is the function of monitoring and responding to threats. An MSSP, or managed security service provider, is a company that delivers that function, and others, as a service. Using an MSSP is one way to obtain a 24/7 SOC without building the whole capability yourself.
