Hybrid working remains a cornerstone for UK SMEs in 2024. Yet many businesses still rely on outdated VPN setups that fail to meet modern security standards. The NCSC has updated its guidance on secure remote access, emphasising zero-trust principles and strong authentication. This post breaks down the latest recommendations and shows how managed IT services help SMEs implement them effectively.

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 some form of hybrid working. For SMEs, this flexibility boosts productivity but introduces new risks around data access and network boundaries.

The NCSC's Secure remote access guidance stresses that traditional VPNs alone are insufficient. They recommend combining VPNs with additional controls such as multi-factor authentication (MFA), device health checks and network segmentation.

NIST's SP 800-46 Rev. 2 on enterprise telework security aligns closely with these views, advocating endpoint protection and continuous monitoring.

Key Updates in the NCSC's 2024 VPN Recommendations

The NCSC has highlighted several priorities for organisations using VPNs:

• Strong authentication: Passwords are no longer enough. MFA must be enforced everywhere.
• Least privilege access: Users should only reach the systems they genuinely need.
• Regular patching and monitoring: VPN appliances and client software must stay current.
• Device compliance: Only managed, healthy devices should connect.

These align with the NCSC's broader Zero Trust principles published earlier this year.

Common VPN Mistakes UK SMEs Still Make

Many Dundee and wider UK SMEs fall into these traps:

1. Using consumer-grade VPNs or free tools for business traffic.
2. Leaving MFA optional for remote workers.
3. Failing to segment networks so a compromised laptop can reach everything.
4. Ignoring client device health before granting access.

Managed service providers catch these issues during regular audits and can enforce policy through centralised tools.

How Managed IT Services Deliver NCSC-Compliant VPN Setups

Partnering with a local managed service provider like Inmotion IT gives SMEs several advantages:

• Centralised policy management: We deploy and maintain enterprise VPN solutions (such as WireGuard or IPsec with MFA) across all devices.
• 24/7 monitoring: Alerts for unusual login attempts or failed authentications are investigated immediately.
• Device compliance checks: Only Windows, macOS and mobile devices that meet your security baseline can connect.
• Regular testing: Quarterly penetration tests and tabletop exercises ensure your remote access remains resilient.

Step-by-Step: Implementing NCSC VPN Best Practices

Step 1: Audit Your Current Remote Access

List every VPN concentrator, user group and connected device. Identify shadow IT solutions staff may be using.

Step 2: Choose the Right Technology Stack

The NCSC recommends modern protocols. We typically deploy:

• WireGuard for performance
• MFA via Microsoft Entra ID or Duo
• Conditional access policies based on location and device health

Step 3: Apply the Principle of Least Privilege

Create role-based access groups. Sales staff should not reach finance servers, for example.

Step 4: Enforce Endpoint Protection

All devices must run approved EDR solutions and receive automatic updates. Non-compliant devices are quarantined.

Step 5: Monitor and Respond

Integrate VPN logs with your SIEM. Set alerts for impossible travel, multiple failed logins and new device registrations.

Step 6: Train Your Team

Run short, regular phishing simulations and explain why MFA prompts appear. Staff buy-in is critical.

Step 7: Review Annually

NCSC guidance evolves. Schedule a yearly review with your managed service provider to stay aligned.

Real-World Benefits for SMEs in Scotland and Across the UK

SMEs that adopt these practices report fewer support tickets related to remote access and greater confidence during audits. One Dundee manufacturing client reduced remote connectivity issues by 70% after moving to a fully managed, NCSC-aligned VPN solution.

Managed services also free internal teams to focus on core business rather than firefighting VPN problems.

Choosing the Right Managed Service Partner

When evaluating providers, ask:

• Do they hold Cyber Essentials Plus certification?
• Can they demonstrate NCSC-aligned deployments for similar-sized organisations?
• What SLAs do they offer for incident response?
• How do they handle device onboarding for new hybrid staff?

Inmotion IT, based in Dundee, specialises in supporting UK SMEs with exactly these requirements. We combine local knowledge with enterprise-grade tools.

Conclusion: Secure Hybrid Working Is Achievable

The NCSC's 2024 VPN guidance provides a clear roadmap. By following zero-trust principles, enforcing MFA and working with an experienced managed service provider, UK SMEs can enjoy the benefits of hybrid working without compromising security.
