CIS critical security controls

CloudTech24 work with businesses to strengthen your cyber defences with CIS Critical Security Controls (CIS 18).

CIS implementation and security controls

At CloudTech24, we help UK businesses implement and maintain the CIS Controls v8.1, the globally recognised cybersecurity framework from the Centre for Internet Security (CIS) that delivers maximum protection against real-world threats.

Our approach is aligned with the official CIS Controls Implementation Guide, ensuring every control is deployed in line with best-practice guidance and prioritised based on your organisation’s size, risk profile, and maturity level. This structured methodology enables us to focus on the safeguards that deliver the greatest risk reduction first, while building a scalable, long-term security posture.

Our end-to-end CIS implementation services cover all 18 controls, from initial gap analysis through to ongoing monitoring and management. We don’t just provide recommendations — we take full ownership of implementation, integrating technical controls, policies, and processes into your existing environment with minimal disruption.

Whether you’re working towards Cyber Essentials Plus, ISO 27001, or strengthening your cyber resilience against modern threats, our CIS-led approach provides a clear, measurable, and proven path to achieving and maintaining compliance.

What is the Center for Internet Security (CIS)?

The Center for Internet Security (CIS) is a non-profit organisation that develops globally recognised security benchmarks. Their CIS Controls are widely used by businesses, governments, and institutions to implement effective cyber security frameworks.
CIS Controls are regularly updated to respond to new and emerging cyber threats—making them one of the most practical and scalable security strategies available.

Why align with the CIS controls?

The CIS 18 controls (formerly known as the SANS Top 20) are a set of actionable, prioritised cybersecurity best practices designed to protect organisations from the most common and impactful threats.
The controls are split into three Implementation Groups (IG1, IG2, IG3), allowing businesses of all sizes to take a scalable approach to security.
Benefits of CIS alignment:

  • Proven protection against modern threats
  • Structured improvement of your security posture
  • Compliance-ready documentation
  • Guidance for both SMEs and large enterprises

Frequently asked questions about CIS security controls

Please see below for some common questions about CIS Security Controls. If you would prefer to speak to someone then give us a call and speak to one of our team in our global HQ to understand your requirements and learn how our security experts support other businesses in the United Kingdom (UK).

CIS Controls (formerly Critical Security Controls) are a set of 18 actionable best practices designed to reduce your organisation’s exposure to cyber threats. They’re used to guide secure IT practices across all industries.

The purpose of the CIS controls is to improve an organisation’s cyber resilience by addressing the most common attack vectors through prioritised, structured guidance.

There are 18 controls in total, as outlined in CIS v8. These form a tiered cybersecurity framework for businesses of all sizes.

While both CIS and NIST are respected cybersecurity frameworks, CIS is more prescriptive and prioritised, making it easier to implement for small and medium-sized organisations. NIST offers a broader, more strategic approach.

CIS cybersecurity compliance is not legally required but is strongly recommended as a baseline security framework. It can also support compliance with other standards such as ISO 27001, GDPR, and NIST.

Yes. The CIS Controls are maintained and updated by cybersecurity professionals worldwide to reflect the latest threat intelligence and best practices.

22/04/2026

Working with CloudTech24 has been a genuinely smooth and valuable experience from start to finish. The onboarding process was structured and efficient, with the team taking time to fully understand our setup, risks, and goals before implementing any solutions.

Day-to-day, their support has been consistently reliable. Issues are handled quickly, often before they become real problems, and there’s a clear proactive approach rather than just reactive fixes.

Their cybersecurity expertise has also added a strong layer of confidence, we know our systems, data, and users are properly protected.

What stands out most is the level of service. Communication is clear, response times are fast, and nothing feels like too much trouble. They operate more like an extension of our team than an external provider, which makes a big difference.

Overall, it’s taken a lot of stress away from managing IT internally and allowed us to focus on growing the business, knowing everything behind the scenes is in safe hands.

CloudTech24 have been a huge support to Positively Adam, providing reliable IT and cybersecurity services here in London.

From day one, their approach has been proactive rather than reactive. Their 24/7 support gives real peace of mind, issues are handled quickly, communication is clear, and nothing feels left hanging. It’s reassuring to know our systems are constantly monitored and protected.

They’ve strengthened our Microsoft 365 setup, tightened our security, and made our overall IT infrastructure far more streamlined and resilient. Most importantly, they explain everything in straightforward terms, which makes decision-making easy and stress-free.

If you’re looking for an IT partner that genuinely adds value and helps your business run smoothly, I highly recommend CloudTech24.

adam sargeson

We’ve been working with CloudTech24 for our IT support and cybersecurity in London, and the service has been outstanding.

Their 24/7 support genuinely makes a difference. Any issues are picked up quickly, resolved efficiently, and communicated clearly, no chasing, no confusion. You can tell they proactively monitor systems rather than just reacting when something breaks.

What really stands out is their professionalism and technical expertise. From Microsoft 365 support to strengthening our overall cybersecurity posture, everything feels structured, secure, and well-managed. They explain technical matters in plain English, which is invaluable for non-technical teams.

If you’re a London-based business looking for reliable, proactive IT support that actually feels like a partnership rather than a helpdesk, I wouldn’t hesitate to recommend CloudTech24.
