Hybrid working is here to stay for UK small and medium-sized enterprises. Yet many businesses still rely on outdated VPN setups that leave data exposed. The NCSC continues to highlight remote access as a key area of concern in its guidance for organisations moving to the cloud.

In this post we break down the latest NCSC advice, explain why traditional VPNs are no longer enough, and show how managed IT services can help you implement secure, scalable solutions.

The Current Remote Access Landscape for UK SMEs

Since 2020, more than 60% of UK SMEs have adopted hybrid or fully remote models. This shift has accelerated digital transformation but also expanded the attack surface.

Traditional VPNs were designed for occasional remote access, not constant connections from personal devices, home networks and third-party locations. According to NIST SP 800-77 Rev 1, older IPsec and SSL VPN configurations often lack modern encryption and granular access controls.

Many Dundee and wider UK businesses still use the same VPN appliance they purchased five years ago. This creates performance bottlenecks and compliance gaps.

Why NCSC Guidance Matters for Your Business

The NCSC’s “Secure Remote Access” principles emphasise zero-trust thinking. Key points include:

• Never trust the network location alone
• Enforce strong authentication on every connection
• Apply least-privilege access rather than full network access
• Monitor and log all remote sessions

Following this guidance helps you meet Cyber Essentials requirements and prepares you for future NCSC alerts.

Five Signs Your Current VPN Is Outdated

1. Users complain of slow speeds when accessing cloud apps
2. You have no visibility into who is connected or what they are accessing
3. MFA is optional or only applied to some users
4. Your VPN concentrator is no longer receiving security updates
5. Contractors and guests receive the same access as permanent staff

If any of these sound familiar, it is time to review your setup.

Moving Beyond Traditional VPNs: Modern Alternatives

NCSC recommends replacing or augmenting legacy VPNs with solutions that support zero-trust network access (ZTNA). Popular options for SMEs include:

• Microsoft Entra Private Access
• Cloud-native secure access service edge (SASE) platforms
• Managed identity-driven gateways

These tools only expose the specific applications users need, rather than the entire network.

How Managed IT Services Deliver Secure Remote Access

Partnering with a local provider such as Inmotion IT removes the burden of evaluating, deploying and maintaining new technology. Our managed service packages typically include:

• 24/7 monitoring of all remote connections
• Automated patching of VPN and identity infrastructure
• Quarterly access reviews aligned with NCSC principles
• Staff training on secure home-working practices

This approach frees your internal team to focus on core business activities while ensuring your remote access remains compliant.

Step-by-Step Implementation Roadmap

Step 1: Assess Current State

Conduct an audit of existing VPN usage, device inventory and authentication methods.

Step 2: Define Access Policies

Work with your managed service provider to map which applications each role actually needs.

Step 3: Deploy Modern Controls

Roll out MFA everywhere and introduce conditional access rules based on device health and location.

Step 4: Test and Monitor

Run tabletop exercises and review logs weekly for the first three months.

Step 5: Review and Improve

Schedule annual reviews against the latest NCSC and NIST publications.

Real-World Benefits for UK SMEs

Businesses that modernise remote access report:

• 40% reduction in helpdesk tickets related to connectivity
• Faster onboarding of new starters and contractors
• Improved staff satisfaction with reliable access from any location
• Stronger position when tendering for contracts that require Cyber Essentials Plus

Common Mistakes to Avoid

• Assuming your existing VPN is “good enough” because it has never been breached
• Relying solely on passwords without MFA
• Granting full network access instead of application-level permissions
• Ignoring mobile and tablet usage in policy design

Conclusion: Act Now Before Guidance Becomes Mandatory

The NCSC continues to refine its remote access recommendations. SMEs that act early will avoid costly emergency upgrades later.
