Coreitech provides expert cyber security consultancy for UK businesses — from risk assessments and Cyber Essentials certification to penetration testing, virtual CISO, and ongoing managed security. Independent, vendor-agnostic, practical advice backed by 15+ years' experience.
What does a cyber security consultant do?
A cyber security consultant is an independent expert who helps organisations assess, improve, and manage their security posture. Unlike in-house IT teams focused on day-to-day operations, a security consultant brings cross-industry expertise, objective assessment, and strategic security guidance.
At Coreitech, our cyber security consultants work with UK businesses across professional services, financial services, healthcare, manufacturing, and the public sector — providing practical, proportionate security advice that fits your business size, risk appetite, and compliance requirements.
Whether you need a one-off cyber security risk assessment, help achieving Cyber Essentials certification, a penetration test, or ongoing strategic security leadership through our virtual CISO service — we provide independent, vendor-agnostic consultancy delivered by certified engineers.
Why use an external cyber security consultant?
Most UK SMEs don't have a dedicated in-house security team — and even those with internal IT staff rarely have the specialist expertise needed for risk assessments, penetration testing, or compliance certification. An external consultant provides:
- Objective, independent assessment — not biased by internal politics or prior decisions
- Specialist expertise across multiple security domains and industries
- Cost-effective access to senior security knowledge without a full-time hire (typically £120k–180k/year)
- Current threat intelligence and knowledge of the latest attack techniques
- Board-credible reporting and evidence of security due diligence
Our cyber security consulting services
From one-off risk assessments to ongoing virtual CISO engagements — all services are fixed-price, scoped upfront, and delivered by certified engineers.

A comprehensive review of your entire IT environment — endpoints, network, cloud, email, and people. We identify vulnerabilities, rank risks by business impact, and deliver a prioritised remediation roadmap.
Cyber Essentials & CE Plus Consultancy
We guide UK businesses through Cyber Essentials and Cyber Essentials Plus certification — the UK Government-backed standard required for NHS, government, and many enterprise supply chains. 100% first-time pass rate.
Security Architecture Consultancy
Design and implement a layered security architecture appropriate for your business size, risk profile, and compliance requirements. From zero-trust network design to endpoint hardening and identity governance.

Penetration Testing
Simulated cyber attacks carried out by our certified ethical hackers to identify exploitable vulnerabilities before real attackers do. Available for internal networks, external perimeters, web apps, and Microsoft 365.
Dark Web Monitoring & Threat Intelligence
Continuous monitoring of dark web forums, breach databases, and threat intelligence feeds for your domains, employee credentials, and business data. Instant alerts when your business is exposed.
Security Awareness Training
Human error is behind 82% of cyber breaches. Our security awareness training programme equips your entire workforce with the knowledge to spot phishing, social engineering, and unsafe behaviour.
ISO 27001 & Compliance Consultancy
We support businesses preparing for ISO 27001 certification, GDPR compliance reviews, NIS2 readiness, and sector-specific frameworks including FCA cyber resilience requirements and NHS DSPT.
