Remote working is now standard for UK SMEs. Yet many businesses still rely on outdated or poorly configured VPNs that leave data exposed. The NCSC regularly updates its advice on secure remote access, and aligning with it has never been more important.

In this guide we break down the current NCSC recommendations, highlight common mistakes and show how partnering with a managed IT services provider delivers enterprise-grade security without the complexity.

Why VPN Security Matters More Than Ever for SMEs

Hybrid working shows no sign of disappearing. According to recent ONS data, over 40% of UK businesses now operate some form of hybrid model. This shift increases the attack surface dramatically.

A compromised VPN can give attackers a direct route into your entire network. The NCSC’s “Secure remote access” guidance emphasises that VPNs must be treated as critical infrastructure, not an afterthought.

SMEs often lack in-house security expertise. That is where managed IT services prove invaluable – they bring the monitoring, patching and configuration skills that keep remote connections safe.

Core NCSC Recommendations You Should Implement Today

The NCSC’s current advice focuses on several key areas:

1. Use modern protocols only

Avoid PPTP and L2TP/IPsec where possible. The NCSC recommends IKEv2/IPsec or WireGuard for better security and performance. These protocols handle mobile connections more reliably.

2. Enforce multi-factor authentication (MFA)

Password-only access is no longer acceptable. NCSC guidance states that MFA should be mandatory for all remote access. Hardware keys or authenticator apps provide the strongest protection.

3. Apply least-privilege access

Users should only reach the resources they genuinely need. Segment your network so a compromised account cannot access everything.

4. Keep VPN software and firmware updated

NIST SP 800-46 Rev. 2 echoes the NCSC’s stance on timely patching. Unpatched VPN appliances remain a favourite target.

Common VPN Mistakes UK SMEs Still Make

Many businesses attempt to manage VPNs internally. The results are often the same:

• Default configurations left unchanged
• No central logging or monitoring
• Split-tunnelling enabled by default
• Expired certificates still in use

These oversights create exactly the kind of weak points highlighted in NCSC alerts. A single misconfigured VPN can undo years of careful security work.

How Managed IT Services Remove the Burden

Rather than expecting your team to become VPN experts, a managed service provider handles the heavy lifting:

• 24/7 monitoring of connection logs
• Automated patching of VPN gateways
• Regular security audits against NCSC baselines
• Rapid response if anomalous activity appears

This approach aligns perfectly with the NCSC’s principle of “secure by design”. You gain the benefits of professional-grade security without hiring extra staff.

Step-by-Step: Building a Compliant Remote Access Solution

1. Assess current setup – Audit every device that connects remotely.
2. Choose approved protocols – Move to IKEv2 or WireGuard.
3. Deploy MFA everywhere – Integrate with existing Microsoft 365 or Google Workspace.
4. Implement network segmentation – Limit lateral movement.
5. Establish continuous monitoring – Use a managed SOC or SIEM solution.
6. Test regularly – Run tabletop exercises and penetration tests annually.

Managed IT partners can deliver all six steps as a single, predictable monthly service.

Real-World Benefits Beyond Compliance

Following NCSC guidance does more than tick boxes. SMEs that adopt proper VPN controls report:

• Fewer helpdesk tickets related to remote access issues
• Faster onboarding for new hybrid staff
• Improved staff confidence when working from home or client sites
• Better insurance terms as cyber posture improves

Choosing the Right Managed IT Partner

Look for providers that:

• Hold Cyber Essentials Plus certification
• Demonstrate experience with NCSC-aligned deployments
• Offer clear SLAs for incident response
• Provide transparent reporting dashboards

Local Dundee-based providers often deliver faster on-site support when hardware needs attention.

Conclusion: Secure Remote Access Is a Business Enabler

Treating VPN security as a managed service rather than a DIY project lets UK SMEs focus on growth instead of firefighting. By following current NCSC guidance you protect data, satisfy clients and create a resilient hybrid workplace.

If your current remote access setup has not been reviewed against the latest NCSC recommendations, now is the time to act. A short consultation with a trusted managed IT services provider can identify gaps and deliver a roadmap that keeps your business secure and productive.
