UK small and medium-sized businesses are embracing hybrid working more than ever. Yet with this flexibility comes increased exposure. The National Cyber Security Centre (NCSC) updated its guidance on secure remote access in 2023-2024, emphasising robust VPN configurations as a foundational control.

At Inmotion IT, we help Dundee and wider UK SMEs implement these recommendations through managed IT services. This post breaks down the key NCSC advice into seven practical steps you can action today.

Why VPNs Remain Critical for UK SMEs in 2024

The NCSC continues to recommend VPNs as part of a defence-in-depth approach for remote access. Their "Secure remote access" guidance highlights that poorly configured VPNs can create single points of failure.

For SMEs without dedicated security teams, this is especially important. Managed service providers can monitor and maintain these connections 24/7, ensuring compliance with NCSC principles.

Step 1: Audit Your Current VPN Setup Against NCSC Baselines

Start by reviewing your existing VPN solution. The NCSC advises using solutions that support modern encryption standards such as IKEv2 or WireGuard where appropriate.

Ask yourself:

Is multi-factor authentication enforced on all VPN connections?
Are split-tunnel configurations disabled by default?

Many SMEs discover legacy setups still running outdated protocols. A managed IT audit typically reveals these gaps within the first week.

Step 2: Implement Strong Authentication – Beyond Passwords

NCSC guidance stresses that passwords alone are insufficient. Combine VPN access with phishing-resistant MFA methods such as hardware keys or authenticator apps.

For UK SMEs handling sensitive client data, this step aligns with both NCSC and upcoming NIS2 considerations. Managed services can centralise MFA policies across your entire workforce.

Step 3: Segment Your Network to Limit Lateral Movement

Even with a strong VPN, flat networks remain risky. The NCSC recommends network segmentation so remote users only reach the resources they need.

Practical actions include:

Creating dedicated VLANs for remote workers
Using conditional access policies
Regularly reviewing firewall rules

This approach reduces blast radius if an account is compromised.

Step 4: Choose the Right VPN Protocol and Encryption

NCSC guidance points to AES-256 encryption as a minimum. Avoid PPTP entirely and consider deprecating older IPSec configurations.

Many businesses benefit from moving to managed SASE (Secure Access Service Edge) solutions that combine VPN functionality with cloud-native controls. Our team at Inmotion IT regularly migrates SMEs to these modern platforms.

Step 5: Monitor and Log All Remote Access Activity

Visibility is key. The NCSC advises logging VPN connections and reviewing them regularly for anomalies.

With managed detection and response services, you gain real-time alerts without needing an in-house SOC. This is particularly valuable for SMEs in regulated sectors such as finance or healthcare.

Step 6: Plan for VPN Scalability and Redundancy

As your team grows or shifts to more remote work, your VPN must scale. NCSC guidance encourages testing failover capabilities.

Consider:

Load-balanced VPN concentrators
Geographic redundancy for cloud-hosted solutions
Regular tabletop exercises simulating VPN outages

Managed service providers handle this infrastructure so you can focus on your core business.

Step 7: Provide Ongoing Staff Training and Policy Updates

Technology alone isn't enough. The NCSC emphasises user awareness. Run short, regular training sessions on safe remote working practices.

Topics to cover include recognising suspicious VPN prompts and reporting lost devices immediately. We embed this training into our managed IT packages for Dundee and UK clients.

How Managed IT Services Make NCSC Compliance Achievable

Implementing these seven steps can feel overwhelming for busy SME owners. Partnering with a local managed service provider like Inmotion IT means you get:

Regular NCSC-aligned audits
24/7 VPN monitoring
Proactive patching and updates
Clear reporting for directors and insurers

This proactive model turns compliance into a business advantage rather than a burden.

Real-World Example: A Dundee Professional Services Firm

One of our clients, a 45-person accountancy practice, migrated from an ageing VPN to a modern zero-trust solution following NCSC guidance. Within three months they reported faster connection speeds and passed their latest cyber essentials assessment with zero non-conformities.
