Controlling which mobile devices can connect to your business network is essential to protect your data and maintain smooth operations. Simply allowing any smartphone, tablet, or laptop to access your systems without oversight can expose your business to cyber risks, data breaches, and operational disruptions. This is especially important as many employees now use personal or company-issued mobile devices to work remotely or on the move.
Why this matters for UK SMEs
When mobile devices connect to your network without proper controls, you risk unauthorised access, malware infections, and accidental data leaks. For example, if a lost or stolen device is not secured, sensitive customer information or financial records could be compromised. This can lead to costly downtime, damage to your reputation, and potential fines under UK GDPR and the Data Protection Act 2018. Furthermore, controlling device access helps you meet Cyber Essentials requirements and supports audit readiness for standards like ISO 27001 or PCI DSS.
A typical scenario
Consider a UK SME with around 50 staff, some working from home and others in the office. Without a clear mobile device access policy, employees might connect personal phones or tablets to the company Wi-Fi, bypassing security controls. One day, a staff member's phone is infected with malware, which spreads to the network, causing system outages and data loss. A managed IT partner would help by implementing Mobile Device Management (MDM) tools, enforcing Multi-Factor Authentication (MFA), and setting up network access controls to ensure only authorised, compliant devices can connect.
Practical checklist to control mobile device access
- Ask your IT provider: Do you offer Mobile Device Management (MDM) solutions that enforce security policies on mobile devices?
- Check for MFA: Are multi-factor authentication methods required for all device logins to the network?
- Review access controls: Can the provider restrict network access to approved devices only, using device certificates or endpoint security checks?
- Audit your current devices: Maintain an up-to-date list of all devices authorised to access your network and regularly review it.
- Enforce encryption and updates: Ensure mobile devices have encryption enabled and receive timely security updates.
- Monitor and log access: Confirm that device access is logged and monitored for unusual activity, supporting incident response and compliance.
- Consider network segmentation: Separate mobile device traffic from critical systems to limit potential damage from compromised devices.
Taking these steps helps reduce the risk of unauthorised access and supports compliance with UK data protection regulations and cybersecurity best practices.
