NCSC VPN Guidelines 2024: What Every UK SME Needs to Know for Secure Hybrid Working

Hybrid working is now the norm for UK small and medium-sized enterprises. Employees expect flexibility, yet this shift introduces new security challenges around remote access. The National Cyber Security Centre (NCSC) has updated its guidance on virtual private networks (VPNs) to help organisations maintain strong protections without compromising productivity.

In this guide we explore the 2024 NCSC recommendations, common VPN mistakes that still catch out SMEs, and how partnering with a managed IT services provider can deliver compliant, low-maintenance solutions.

Why VPN Security Matters More Than Ever for UK SMEs

Remote and hybrid models are here to stay. According to recent ONS data, over 40% of UK businesses now operate with significant remote elements. This creates an expanded attack surface that traditional perimeter security cannot cover.

A properly configured VPN encrypts traffic between user devices and corporate resources, preventing interception on public Wi-Fi or home networks. However, outdated or poorly managed VPN setups can become single points of failure.

NCSC guidance emphasises that VPNs must be treated as critical infrastructure rather than a simple add-on. Their latest publications stress continuous monitoring, strong authentication, and regular configuration reviews.

Key NCSC Recommendations for VPN Deployment

The NCSC’s current advice draws from both domestic research and alignment with NIST SP 800-77. Core principles include:

• Strong authentication: Mandate multi-factor authentication (MFA) on all VPN connections. Password-only access is no longer acceptable.
• Least privilege access: Users should only reach the specific resources required for their role.
• Endpoint health checks: Ensure devices meet security standards before granting access.
• Logging and monitoring: Retain connection logs for at least 12 months to support incident response.
• Regular patching: Keep VPN gateways and client software updated within defined SLAs.

These measures reduce risk while supporting the flexible working that modern SMEs need.

Five Common VPN Mistakes UK SMEs Still Make

Many businesses continue to rely on consumer-grade VPNs or legacy configurations. Here are the issues we see most often:

1. Using the same VPN credentials across multiple users – This destroys accountability and makes breach investigation nearly impossible.
2. Skipping endpoint verification – Allowing unmanaged personal devices to connect opens doors to malware.
3. Outdated encryption protocols – Supporting legacy options such as PPTP or weak ciphers undermines the entire tunnel.
4. No split-tunnelling policy – Forcing all traffic through the VPN can create performance bottlenecks and encourage workarounds.
5. Infrequent access reviews – Former employees or contractors retain access long after they should.

Addressing these five points alone brings most SMEs into line with current NCSC expectations.

How Managed IT Services Deliver NCSC-Compliant VPN Solutions

Implementing and maintaining these controls in-house is resource-intensive. A managed service provider (MSP) specialising in SME IT support can handle:

• 24/7 monitoring of VPN gateways
• Automated patching and certificate management
• Quarterly access reviews aligned with NCSC logging requirements
• Staff training on secure remote working practices
• Integration with existing Microsoft 365 or Azure environments

At Inmotion IT we deploy solutions based on enterprise-grade platforms that meet NCSC design principles out of the box. Our clients receive monthly compliance reports showing authentication success rates, failed login attempts, and patch status.

Step-by-Step: Building a Future-Proof VPN Strategy

Step 1: Audit Current Remote Access

Map every user who connects remotely and document the resources they need. Identify any shadow IT VPNs or unsanctioned tools.

Step 2: Choose the Right Architecture

Modern deployments favour always-on, device-tunnel or per-app VPN models rather than full-tunnel solutions. NCSC recommends evaluating cloud-native options that scale with your headcount.

Step 3: Enforce MFA and Conditional Access

Link VPN authentication to your identity provider. Use risk-based policies that block connections from unusual locations or non-compliant devices.

Step 4: Segment Your Network

Apply zero-trust principles by placing VPN users into isolated VLANs or virtual networks. This limits lateral movement if a device is compromised.

Step 5: Establish Ongoing Governance

Schedule quarterly reviews of user access, encryption standards, and log retention. Document everything for NCSC-aligned audits or cyber insurance requirements.

Measuring Success: KPIs for Secure Remote Access

Track these metrics to demonstrate improvement:

• Percentage of remote sessions using MFA (target: 100%)
• Average time to patch critical VPN vulnerabilities (target: <7 days)
• Number of failed authentication attempts per month
• User satisfaction scores for remote access speed

Regular reporting helps justify continued investment to directors and supports digital transformation goals.

The Business Case for Professional VPN Management

Beyond compliance, properly managed VPNs deliver tangible benefits:

• Reduced downtime from connectivity issues
• Lower insurance premiums through demonstrated cyber controls
• Improved employee productivity thanks to reliable, fast connections
• Competitive advantage when tendering for contracts that require NCSC-aligned security

Conclusion: Act Now on NCSC VPN Guidance

The NCSC continues to highlight remote access as a high-risk area. UK SMEs that modernise their VPN posture now will avoid costly incidents later while enabling the flexible working their teams expect.
