Cybersecurity services for UK businesses
Managed cyber security services that identify what is exposed, monitor what matters, and respond fast when something gets through. Built around Cyber Essentials, ISO 27001 alignment and the controls your insurers and clients increasingly demand as standard.
The cyber security risks every UK business now faces
Ransomware is no longer rare. UK businesses of every size are being targeted, and the average cost of a serious incident now reaches into the millions when downtime, recovery and reputational damage are counted together.
Compliance demands are tightening. GDPR, Cyber Essentials, the FCA’s operational resilience expectations and sector-specific frameworks require documented controls, not assumptions.
People remain the route in. Most breaches still involve a person – a phishing click, a reused password, a missed update. Technical controls alone do not close the gap.
Unseen gaps do the damage. Without regular assessment, security weaknesses stay invisible until an attacker finds them.
Our approach to managed cyber security
We prevent more than we react to. Highgate’s cyber security services combine current detection technology with human expertise from our UK-based Security Operations Centre, so you can:
– Identify vulnerabilities before attackers do, through penetration testing and security gap analysis.
– Monitor and respond around the clock with SOC-as-a-Service, detecting and containing threats in real time.
– Build a security-aware culture with human risk management training that turns staff from a weakness into a defence layer.
– Hit compliance with Cyber Essentials, Cyber Essentials Plus and industry-specific frameworks handled end-to-end.

Sectors we protect
Cybersecurity services for every sector. The three industries where the regulatory pressure and the data sensitivity make this work most urgent:
Cyber attacks on UK financial services firms are among the most frequent and most sophisticated in any sector. We help banks, insurers, wealth managers and chartered accountancies meet FCA and PRA expectations, protect client data, and put in place the controls regulators and clients now treat as the floor.
Law firms hold some of the most sensitive data in existence and attackers know it. A single breach can compromise client confidentiality, trigger SRA regulatory action and cause reputational damage that takes years to recover from. We help legal practices put the right controls in place and respond effectively when an incident occurs.
Government bodies handle sensitive citizen data and deliver critical public services. We help central government organisations meet NCSC guidance, achieve Cyber Essentials certification, and build the security posture that protects both their data and the public trust they depend on.

Cybersecurity insights
Cybersecurity services: frequently asked questions
What is Cyber Essentials and do I need it?
Cyber Essentials is a UK government-backed certification confirming that your business has the basic controls in place to defend against the most common cyber attacks. It is increasingly required by clients, insurers and public sector supply chains, and for many businesses it is the fastest way to demonstrate that security is taken seriously at board level. If you handle customer data, work with government contracts, or want cyber insurance at a sensible premium, you almost certainly need it.
How long does a penetration test take?
It depends on scope, but most penetration tests for mid-market organisations take between three and ten days. A focused test on a single application or network segment sits at the shorter end; a full infrastructure test across multiple sites takes longer. We scope every engagement before work begins, so you know the timeline and what is covered upfront.
What's included in your SOC-as-a-Service?
24/7 threat monitoring, detection and response from our UK-based Security Operations Centre, without the cost of building one in-house. That includes continuous monitoring of your endpoints, network and cloud environments, real-time alerting, triage by our analysts, and escalation and response when a genuine threat is identified. Regular reporting demonstrates your security posture to leadership, insurers and clients.
How quickly can you respond to a security incident?
Our incident response team is available around the clock and can begin remote triage within the hour. For situations requiring on-site support, we can typically mobilise within 24 hours. Speed matters in a security incident; the faster containment begins, the lower the impact on your data, your operations and your reputation.
What happens to my business if a cyber attack gets through?
Even with strong defences in place, no security posture is completely impenetrable. That is why cyber security and business resilience work hand in hand — a tested recovery plan means that if the worst does happen, you can restore operations quickly and contain the impact.
