Security Guidance for SMEs: What the NCSC Recommends and How to Apply It
Cyber security is no longer just an IT concern — it’s a fundamental business requirement. For small and medium-sized organisations, the challenge is often knowing where to start and which actions genuinely reduce risk.
To address this, the National Cyber Security Centre (NCSC) has produced clear, practical guidance specifically for SMEs. The Small Business Guide infographic below highlights the five most effective cybersecurity actions organisations can take to protect themselves against common cybersecurity threats.
At ABCOM, we help UK organisations turn this national guidance into practical, day-to-day protection — aligned with Cyber Essentials and delivered to the standards required of an NCSC Assured Service Provider (ASP).
Why NCSC Guidance Matters for Small Businesses
The NCSC is the UK government’s authority on cybersecurity. Its guidance is based on real-world attack data and focuses on controls proven to reduce risk from the most common threats, including phishing, malware, ransomware, and unauthorised access.
For SMEs, this guidance is deliberately pragmatic. It doesn’t require enterprise-level budgets or specialist teams — just consistent application of the right security fundamentals.
These same principles also form the foundation of Cyber Essentials, the UK’s baseline cybersecurity standard required by many suppliers, insurers, and public-sector organisations.
The Five Cyber Security Basics Every SME Should Have in Place
1. Backing Up Your Data
Regular, reliable backups ensure your business can recover quickly from incidents such as ransomware, accidental deletion, or hardware failure.
Best practice includes automated backups of key systems and cloud data, keeping backups isolated from your main network, and testing restores to ensure they work when needed.
2. Using Strong Passwords and Multi-Factor Authentication
Weak or reused passwords remain one of the leading causes of cyber breaches.
The NCSC recommends unique passwords for business systems, using password managers rather than shared documents, and enabling multi-factor authentication (MFA) wherever possible to reduce the risk of account compromise.
3. Keeping Devices and Software Secure
Unpatched systems are a common entry point for attackers.
This includes ensuring operating systems and applications are kept up to date, removing unsupported software, and securing laptops and mobile devices used for work. These controls are central to meeting Cyber Essentials requirements.
4. Protecting Against Phishing and Malware
Phishing emails remain the most common cyber attack facing SMEs.
Effective protection combines technical controls such as email filtering and endpoint protection with user awareness, clear reporting processes, and ongoing monitoring.
5. Using Firewalls and Network Protection
A properly configured firewall helps prevent unauthorised access to your systems and data.
For most SMEs, this means a managed boundary firewall, secure remote access, and sensible network configuration — all areas where professional setup and ongoing management make a significant difference.
How This Links to Cyber Essentials
If this guidance feels familiar, it’s because Cyber Essentials is built directly on NCSC best practice.
Achieving Cyber Essentials helps organisations demonstrate that essential cyber security controls are in place, significantly reducing the risk of common attacks while supporting customer confidence and compliance requirements.
ABCOM is an NCSC Assured Service Provider for Cyber Essentials, meaning our services are independently assessed to ensure they meet the required national standards. This gives organisations confidence that guidance is being applied correctly, not just interpreted loosely.
