AI SOC vs hiring a SOC team: build vs buy

Running a security operations centre around the clock is a staffing problem before it is a tooling problem. Covering 168 hours a week with no single point of failure means five or more analysts on a shift rota, plus a SOC lead and a manager to set detections, run handovers, and own escalations. Add SIEM licensing, on-call, training, and recruitment, and a genuine 24/7 function lands north of £500k a year fully loaded.

The cost is only half of it. Hiring and ramping a team typically takes 6 to 12 months, and SOC analyst churn is high, so you are re-hiring and re-training on a rolling basis. For a small-to-mid organisation, that is a large fixed commitment to stand up before a single alert is investigated.

An AI SOC does the first-pass triage and investigation work at machine speed, on top of the tooling you already run. OwlSOC connects to Microsoft Sentinel, Microsoft Defender (Endpoint and Office), and AWS Security Hub, read-only by default, with no agents to install. When an alert fires, standard deterministic triage scores every alert, and the AI investigation step pulls the relevant logs, builds an evidence-linked timeline where every claim cites a source log or pivot ID, maps the activity to MITRE ATT&CK, and returns a plain-language verdict, typically in under two minutes, 24/7.

Verdicts are hedged on purpose: likely true positive, likely false positive, or uncertain and needs review. The AI investigation, which carries the calibrated confidence and the root-cause narrative, is a separate step included in the paid tiers, not the base output. OwlSOC investigates and recommends; a human on your team approves any action before it runs, and execution is write-grant-gated through a write connector. It is not autonomous.

The honest comparison is not feature-for-feature, it is what you are committing to and how fast you get coverage. A team gives you deep human judgement and the ability to handle anything, at a high fixed cost and a long lead time. An AI SOC gives you consistent 24/7 triage and investigation across every alert, live in days, billed monthly with no minimum term.

Be clear-eyed about the boundary. An AI SOC does first-pass triage and investigation; it does not replace a security function, threat hunting, detection engineering, or incident command. If you have no security capability today, OwlSOC gives you 24/7 coverage you would otherwise have no way to afford, and a human still approves anything that touches your environment.

If you already have analysts, the value is different. Instead of working a queue of raw alerts, your team receives confirmed, evidence-linked cases with the timeline, the MITRE mapping, the affected entities already resolved, and a recommended action ready for approval. The repetitive triage that burns out analysts gets handled before it reaches them, so their time goes to the cases that genuinely need a human.

Build an in-house 24/7 SOC when the scale, regulatory posture, or risk profile justifies a permanent team and you can absorb the cost and the hiring timeline. Buy an AI SOC when you need coverage now, you run Sentinel, Defender, or AWS, and you want to prove value before committing budget. The two are not mutually exclusive: many teams run OwlSOC as the always-on first pass and keep their analysts for the work that needs them.
