Cybersecurity team structure: who to hire, in what order

By TalentDock Editorial Team · Updated 27 September 2026 · 7 min read

Quick answer

Most organisations build a security team in layers: a named owner of security risk first, then an engineer to fix the basics, then an analyst to monitor and manage vulnerabilities, then specialists (cloud, application security, GRC, incident response) as the estate and compliance needs grow. Round-the-clock monitoring is a separate decision, because it needs at least five people per seat or a managed service.

Hiring order

The order most teams hire in

1 · Owner

A named UK leader accountable for security risk: CISO, head of security or CTO.

2 · Engineer

A security engineer to deploy MFA, EDR, logging and hardening.

3 · Analyst

A cyber security analyst for alerts, vulnerabilities and reporting.

4 · Compliance

A GRC analyst once customers or regulators ask for ISO 27001, SOC 2 or DORA.

5 · Specialists

Cloud, AppSec, DevSecOps, IAM and testing as your estate demands.

6 · Operations

SOC analysts and incident response for extended or 24/7 cover.

By size

Team shapes by company size

Typical security team by organisation size
Organisation	Typical team	Notes
Under 50 staff	Part-time owner + 1 analyst or engineer	Lean on your IT provider and an MDR for nights
50-250 staff	Owner + engineer + analyst	Add GRC when questionnaires pile up
250-1,000 staff	Head of security + 4-8 specialists	Engineering, analysts, GRC, IAM, cloud
1,000+ or regulated	CISO + multiple teams	SOC, engineering, architecture, GRC, testing, IR

These are starting points, not rules; regulated firms and software companies usually need more security staff earlier.

SOC tiers

How a SOC team is organised

Tier 1

Triage alerts, close false positives, escalate with evidence.

Tier 2

Investigate, scope and contain confirmed incidents.

Tier 3 / hunting

Threat hunting, detection engineering, complex investigations.

SOC lead

Quality, rota, metrics and escalation to the UK owner.

Reporting lines

Where security should report

Security often starts inside IT, reporting to the CTO or IT director. As risk grows, many organisations move it to report to the CEO, COO or risk function so it can challenge IT decisions. The UK government’s Cyber Security Breaches Survey 2025/26 found board-level responsibility for cyber rose to 31% of businesses.

Offshore

Where offshore roles fit

Keep the owner, regulator-facing and clearance-bound roles in the UK. Engineers, analysts, SOC staff, testers and GRC analysts can work offshore for a fraction of the UK cost. See dedicated cybersecurity teams for ready-made structures and prices.

FAQ

Frequently asked questions

Who should be the first cybersecurity hire?

Usually a hands-on security engineer, with a named leader owning risk. Monitoring without fixed basics produces noise.

How many security staff should a company have?

There is no fixed ratio. Size, sector, regulation and how much you build in-house matter more than headcount.

How many analysts does a 24/7 SOC need?

At least five per seat to cover shifts, leave and sickness.

Should security report to the CTO?

It often starts there. As risk grows, many organisations move it outside IT for independence.
