Cyber security
Always stay one step ahead
The bad news is that the bad guys are getting even smarter. The good news? So are the good guys. Our experience and expertise as cyber security experts, along with our partnerships with some of the leading security vendors in the business, will ensure you’re fully protected against even the most sophisticated cyber threats.
Why UK businesses need cyber security services
Cyber attacks on UK businesses are increasing in both frequency and sophistication. According to the UK government’s Cyber Security Breaches Survey 2026, around 43% of UK businesses reported experiencing a cyber breach or attack in the past 12 months. AI-powered phishing campaigns are now indistinguishable from legitimate communications, ransomware is increasingly targeting UK SMEs who are seen as easier targets than large enterprises, and supply chain attacks mean a vulnerability in one of your suppliers can quickly become a vulnerability in your own business.
The cost of a breach extends far beyond the immediate financial impact. Regulatory fines under UK GDPR can reach £17.5 million. Reputational damage can affect client relationships for years. And the operational disruption of a ransomware attack, where systems are taken offline for days or weeks, can be existential for smaller businesses. Investing in managed cyber security services before an incident is significantly less costly than recovering from one.
How Arc’s cyber security services protect your business
Effective cyber security is not a product you buy once: it’s an ongoing programme of monitoring, assessment, and improvement that keeps pace with a constantly evolving threat landscape. Arc’s cyber security services take a layered approach, combining technical controls, human awareness, and continuous monitoring to protect your business from every angle.
We start with an assessment of your current security posture, identifying the gaps between where you are and where you need to be. From there, we implement the right combination of cyber security services for your risk profile and budget, whether that is Managed Detection and Response for continuous threat monitoring, Cyber Essentials certification to demonstrate baseline security to clients and insurers, or a full Arc Threat Lens assessment to give you a complete picture of your IT estate’s security maturity.
Arc’s cyber security credentials
Arc is ISO 27001 certified for information security management, Cyber Essentials Plus certified, and ISO 9001 certified for quality management. We have been shortlisted for Healthcare and Life Sciences Technology of the Year at the National Technology Awards and are consistently recognised as a leading UK cyber security company. When you work with Arc on cyber security services, you are working with a provider that holds itself to the same standards it applies to your business.
Why Cyber Essentials is essential for UK businesses
Cyber Essentials certification is no longer optional for many UK businesses. It is mandatory for any organisation bidding for central government contracts involving sensitive information, and is increasingly required by enterprise clients, cyber insurers, and supply chain partners across the UK. The v3.3 update that took effect in April 2026 introduced stricter requirements around multi-factor authentication and cloud service coverage. Arc supports UK businesses through both Cyber Essentials and Cyber Essentials Plus, from initial gap analysis through to certification submission and beyond.

- Improve security: pen testing provides insights to strengthen defences and patch weaknesses
- Helps businesses meet compliance regulations (such as GDPR or ISO 27001)
