Outsourced SOC vs in-house SOC: what UK businesses should weigh up

Every growing business eventually asks who watches the alerts at 2am. The choice usually comes down to building your own security operations centre, outsourcing it, or mixing the two. Here's how to think it through.

What an in-house SOC gives you

Your own analysts learn your systems, your people and your normal traffic. They can act fast without a contract in the way, and you keep full control of your data and detections. The trade-off is that round-the-clock coverage needs several analysts per seat once you account for shifts, holidays and sickness — and security analysts are hard to hire and retain.

What outsourcing gives you

An outsourced or managed SOC gives you coverage quickly, without recruiting a full team. It suits businesses that need monitoring now, or that only need cover outside office hours. The risks are a provider that doesn't really know your environment, generic alert handling, and lock-in to the provider's own tooling.

The questions that decide it

• Which hours do you actually need covered? Office hours only, extended hours, or 24/7?
• Who owns the tools and the data? Will analysts work in your SIEM and EDR, or move you onto theirs?
• What happens at escalation? Who on your side gets the call, and with what information?
• How mature is your logging? More analysts looking at poor data won't make you safer.
• Is this a stopgap or a long-term model? The answer changes what you should sign.

The hybrid model most teams end up with

Many organisations keep a small core team who own detections, escalation and context, then extend coverage with contract analysts working in other time zones. That combines the knowledge of an in-house team with the hours of an outsourced one. Our SOC-as-a-Service works this way: analysts plug into your existing tools rather than replacing them.

What drives the cost

Whichever route you take, cost is driven mainly by the hours covered, the seniority of analysts, alert volume, and whether analysts are UK-based or working from lower-cost regions with good time-zone overlap. Ask any provider to price against those factors explicitly so you can compare like for like.

Frequently asked questions

Is an outsourced SOC cheaper than an in-house SOC?

Often, especially for 24/7 coverage, because you avoid hiring enough analysts to staff every shift. The cost depends on hours covered, analyst seniority, alert volume and where analysts are based.

Can I combine in-house and outsourced SOC coverage?

Yes. A common model is a small in-house team that owns escalation, with contract or outsourced analysts covering nights, weekends or other time zones.
