UK small and medium-sized enterprises are embracing hybrid working more than ever. Yet with this flexibility comes increased exposure to cyber threats targeting remote connections. The National Cyber Security Centre (NCSC) recently refreshed its guidance on virtual private networks, emphasising stronger authentication, modern protocols, and ongoing monitoring.
In this post we break down the key updates, explain why they matter for your business, and provide actionable steps you can take today.
Why VPN Security Matters More Than Ever for UK SMEs
Remote and hybrid working are now standard. According to recent ONS data, over 40% of UK SMEs operate some form of flexible working arrangement. This shift has expanded the attack surface dramatically.
Attackers increasingly target VPN endpoints because they serve as gateways to corporate resources. Weak configurations or outdated software can allow unauthorised access to email servers, file shares, and customer databases.
The NCSC’s updated advice focuses on moving beyond “set and forget” VPN deployments. Instead, organisations are encouraged to treat VPNs as part of a broader zero-trust approach.
Key NCSC Recommendations in the 2024 Guidance
1. Adopt Modern Protocols
The NCSC now explicitly recommends WireGuard or IKEv2 with strong cipher suites over older PPTP or L2TP options. These protocols offer better performance and built-in security features.
2. Enforce Multi-Factor Authentication (MFA)
All VPN access should require MFA. Passwords alone are no longer considered sufficient, even for smaller organisations.
3. Implement Least Privilege Access
Users should only reach the specific resources they need. Full network access should be the exception rather than the default.
4. Regular Auditing and Patch Management
VPN appliances and client software must be kept up to date. The NCSC stresses continuous monitoring for unusual login patterns.

Common Mistakes SMEs Still Make
Many businesses we support at Inmotion IT still run legacy VPN setups. Here are the issues we see most often:
- Using consumer-grade routers with basic VPN passthrough
- Failing to rotate pre-shared keys for years
- Granting full network access to all remote users
- No central logging or alerting on failed login attempts
These oversights directly contradict current NCSC guidance and leave organisations vulnerable.
How Managed IT Services Help You Stay Compliant
Implementing the NCSC’s VPN recommendations requires ongoing expertise. For most SMEs this is best achieved through a managed service provider that can:
- Audit existing remote access infrastructure
- Deploy and configure modern VPN solutions
- Integrate MFA across all devices
- Provide 24/7 monitoring and rapid response
- Deliver regular compliance reports aligned with NCSC expectations
A managed approach removes the burden from internal staff who already have full-time responsibilities.
Practical Implementation Roadmap
Phase 1: Assessment (Weeks 1-2)
Conduct a full inventory of current remote access methods and identify any non-NCSC-compliant configurations.
Phase 2: Design (Weeks 3-4)
Design a segmented network architecture using modern protocols and conditional access policies.
Phase 3: Deployment (Weeks 5-8)
Roll out updated VPN clients with MFA. Test thoroughly with a pilot group before organisation-wide deployment.
Phase 4: Ongoing Management
Establish monthly reviews, automated patching, and quarterly NCSC-aligned security assessments.
Measuring Success
Track metrics such as:
- Percentage of remote users protected by MFA
- Average time to apply critical VPN patches
- Number of blocked suspicious login attempts
These KPIs demonstrate both improved security posture and readiness for future NCSC audits or Cyber Essentials Plus certification.
Conclusion
The NCSC’s 2024 VPN guidance is clear: outdated remote access setups are no longer acceptable for organisations that value their data and reputation. UK SMEs that act now will not only reduce risk but also build a more resilient foundation for hybrid working.
At Inmotion IT we specialise in helping businesses implement these exact recommendations through our managed IT services. If your current VPN setup hasn’t been reviewed in the past 12 months, now is the time to act.
