Security
Managed network security, threat detection and incident response — built around your organisation, not bolted on afterwards.
We work alongside your existing IT provider to make sure every layer of your security is in place and properly maintained. We do not replace your IT team — we make sure the security foundations are solid, regardless of who manages the day-to-day.
From firewall hardening and intrusion detection through to cloud environment audits and 24/7 monitoring, we bring 27 years of hands-on network security experience to organisations that cannot justify a full-time security team.
We also manage Cyber Essentials certification, IASME Cyber Assurance and ISO 27001 readiness — so your security posture and your certification evidence are maintained by the same people who actually secure your network.
Cyber Essentials
Managed certification from initial assessment through to Cyber Essentials Plus. We fix the technical issues first, so you pass the assessment rather than just filling in a form.
Security Awareness Training
Training people actually remember. From 30-minute masterclasses to full-day events with live hacking workshops and police cyber crime speakers.
ISO 27001 Readiness
Practical preparation for ISO 27001 certification. We build your management system around controls that are genuinely in place, so the assessment becomes a formality rather than a discovery exercise.
Network Security
Ransomware-as-a-service, supply chain compromise, credential theft, insider threats — the landscape has changed beyond recognition since 1999. What hasn't changed is the need for someone who understands your network to stand between it and everything trying to get in.
- Firewall configuration review and hardening
- Intrusion detection and prevention
- Threat monitoring and incident response
- Traffic analysis and anomaly detection
- Access control and audit trail review
- Coordination with your IT provider on remediation
Cloud Environment Security
Most organisations run critical operations through Microsoft 365, Google Workspace or similar platforms. The cloud provider protects their infrastructure. The configuration, access controls and user management are entirely your responsibility.
We audit your cloud environment and fix what we find. Common problems include former employees still holding admin access, service accounts with excessive permissions, shared mailboxes with no access controls, and global admin rights handed out to IT suppliers who no longer work with you.
Continuous Monitoring
When something does go wrong, our monitoring means you can recognise the intrusion, provide forensic evidence and audit trails, contain the breach, and meet your 72-hour reporting obligation — because the right systems were in place all along.
