🔐 Cybersecurity Fundamentals for UK SMBs: Protecting Your Business in 2025

Written by Eve Cooper | May 18, 2025 3:46:03 PM

 

In today’s digital-first economy, UK small and medium-sized businesses (SMBs) face a growing wave of cyber threats.

According to the UK Government’s Cyber Security Breaches Survey 2024,

  • 43% of UK businesses experienced a cybersecurity breach or attack in the last 12 months.

  • 84% of attacks involved phishing, and

  • The average cost per breach is now over ÂŁ3,230 for SMBs.

With regulatory pressure increasing through GDPR and the forthcoming Cyber Security and Resilience Bill, it’s never been more important to get the fundamentals right.

 

📋 The Essentials: Aligning to Cyber Essentials & ISO 27001

To help mitigate risk, the UK Government encourages SMBs to work toward Cyber Essentials or ISO/IEC 27001, both of which provide structured frameworks to manage cybersecurity risk and demonstrate due diligence.

 

Here’s how SMBs can align with both standards:

1. Secure Your Network and Devices

Cyber Essentials: Requires firewalls, secure configuration, and access control.
ISO 27001: Controls like A.13.1 (network security) and A.9.2 (user access management).

 

How RockSec360 helps:

  • We deploy and manage next-gen firewalls and secure endpoint protection.

  • Our Unified platform prevents malware, data exfiltration, and suspicious access attempts across your environment.

2. Maintain Access Control and Least Privilege

Cyber Essentials: Only necessary users should access your systems.
ISO 27001: Includes A.9 (Access Control) and A.12.4 (Logging and monitoring).

 

How RockSec360 helps:

  • We implement identity and access management best practices.

  • We monitor for abnormal access using AI-driven behavioural analysis.

3. Protect Against Malware and Ransomware

Cyber Essentials: Requires anti-malware protection on all devices.
ISO 27001: A.12.2 (Protection from malware).

 

How RockSec360 helps:

  • Our endpoint protection stack360 includes anti-malware, threat detection, and web filtering.

  • Regular vulnerability scanning and patch management are provided via our IT Helpdesk and automated tools.

4. Keep Devices and Software Updated

Cyber Essentials: Critical updates must be applied within 14 days.
ISO 27001: A.12.6.1 (Controls against technical vulnerabilities).

 

How RockSec360 helps:

  • We manage patching, updates, and firmware upgrades for all enrolled devices.

  • Our IT Helpdesk ensures zero-day vulnerabilities are promptly addressed.

5. Backup and Recover Critical Data

ISO 27001: A.12.3 (Backup), A.17.1 (Business continuity planning).
(Not required for Cyber Essentials, but critical in practice.)

 

How RockSec360 helps:

  • We offer fully managed, encrypted backups, including file-level, image, and cloud-to-cloud backups (e.g. Microsoft 365).

  • Automated recovery testing ensures business continuity.

6. Raise Security Awareness and Reduce Human Error

Cyber Essentials: Encourages user education on phishing and secure practices.
ISO 27001: A.7.2.2 (Information security awareness, education, and training).

 

How RockSec360 helps:

  • We deliver continuous Security Awareness Training (SAT), simulated phishing campaigns and e-learning. 

  • Monthly reports track progress and high-risk users.
