Managed SOC vs in-house SOC: the real cost

Building a 24/7 security operations centre in-house means hiring 8 to 12 analysts and standing up a stack of tooling, at $600K to $1M or more a year before you detect a single threat. A managed SOC delivers the same always-on coverage as a service, usually at a fraction of that cost. Which one is right depends on your scale, but for most companies below large-enterprise size, managed wins on both cost and capability.

What a SOC actually has to do

A SOC has one deceptively simple job: watch everything, all the time, and act when something is wrong. That means ingesting alerts from across your stack, triaging them, investigating the real ones, and responding fast enough to matter. The hard part is not the watching. It is the “all the time”.

Attackers do not keep office hours. Recent campaigns move from initial access to impact in under an hour, often at night or over a weekend precisely because that is when defenders are thin. Coverage that stops at 6pm is not really coverage.

The true cost of an in-house SOC

This is where the numbers surprise people. To staff a genuine 24/7 rotation, with cover for nights, weekends, holidays and leave, you need roughly 8 to 12 analysts. Before a single tool, that is $600K to $1M or more a year in salaries and training.

Then add the rest:

• Tooling: SIEM, EDR, threat intelligence and automation, licensed and maintained.
• Turnover: SOC roles see 20 to 30 percent annual churn, and alert-fatigue burnout is the norm. Every departure is a re-hire and a re-train.
• Time: standing up a capable SOC takes months to a year. That is a year of exposure while you build.

For a large enterprise with the scale to absorb it, that can be the right call. For everyone else, it is a heavy, fragile investment that struggles to stay fully staffed.

What a managed SOC gives you instead

A managed SOC turns all of that into a service:

• Coverage in weeks, not quarters, onboarded against the stack you already own.
• No hiring or retention risk. The provider carries the team, the rota and the burnout.
• Tooling included, tuned and maintained for you.
• Predictable, scalable cost that flexes with your coverage rather than your headcount.

The result is enterprise-grade operations without an enterprise-grade team to build and defend.

Where in-house still makes sense

Managed is not always the answer. Very large organizations, highly unusual environments, or strict data-residency rules can justify an in-house build. The data-residency concern is worth a closer look, though: a good managed provider hosts in your region and keeps your raw logs in your environment, so “we cannot send our data out” is rarely the blocker it once was.

The AI-first option

There is now a third path that changes the maths again. Cid, our managed SOC, is AI-first: AI agents investigate every alert in seconds with written reasoning, and senior analysts own the escalations that actually matter. You get 24/7 coverage, every alert genuinely looked at rather than sampled, and a cost that lands well below an 8 to 12 analyst rotation, because a small expert team can cover many clients at once.

How to decide

A quick way to think about it:

1. Do you need true 24/7? If yes, and you are not enterprise-scale, the in-house maths rarely works.
2. Can you hire and retain SOC talent? It is one of the hardest roles to keep staffed.
3. What is your alert volume? A thousand-plus alerts a day is far past what a small team can read with care.
4. What is the cost of one missed breach? Prevention is almost always cheaper than remediation.

For most companies, the honest answer points to managed. The question worth asking is not “build or buy”, but “how do we get always-on coverage we can afford and trust”. If that sounds like your situation, Cid is built for exactly it.
