Network security, managed by our UK engineers
From firewall rulesets to intrusion prevention and secure remote access — we design, deploy and manage the controls around your infrastructure.
Managed Firewalls
Dedicated and shared hardware firewalls configured, maintained and patched by our engineers. Granular rulesets, NAT, port forwarding and change management handled for you — with full audit trails.
Intrusion Detection & Prevention
Real-time IDS/IPS inspection identifies and blocks malicious activity — port scans, brute-force attempts, exploit signatures and anomalous traffic — before it reaches your servers.
VLANs & Network Segmentation
Private VLANs isolate your infrastructure from other tenants and segment internal tiers — keeping databases, applications and management traffic on separate, firewalled networks.
VPN & Secure Remote Access
Site-to-site IPsec tunnels link your offices to your hosted infrastructure, while SSL VPNs give your team encrypted remote access — without exposing management ports to the internet.
Vulnerability Management
Proactive scanning identifies exposed services, outdated software and misconfigurations across your estate, with prioritised remediation guidance from our security team.
24/7 Monitoring & Response
Our UK NOC monitors traffic patterns, security events and system health around the clock — with rapid escalation and hands-on response when something needs attention.
Four layers between attackers and your data
Security isn't a single product — traffic passes through every layer of our stack before it reaches your workloads.
01Network Edge

- BGP route filtering & RPKI validation
- Upstream blackhole & rate-limiting controls
02Network Layer
Firewall appliances- Managed hardware firewalls & rulesets
- IDS/IPS real-time inspection
- Private VLANs & tenant isolation
03Server Layer
Dedicated servers- Host firewalls & hardening
- Anti-virus & malware protection
- OS patching on managed plans
04Data Layer
Cyber Protection & Backups- Encrypted automated backups
- Acronis Cyber Protect integration
- Off-site retention & recovery testing
From colocation edge to hybrid VPN
Whether you host with us or colocate your own kit, we secure the perimeter and the paths in between.
Colocation perimeter
Segment VLANs in front of your rack, enforce firewall rules at the edge and terminate site-to-site VPNs into your Cambridge cabinet.
Hosted VPS & dedicated
Managed firewalls and IDS/IPS in front of cloud VPS and bare-metal servers — with private networking between instances.
Office-to-DC VPN
IPsec tunnels from your HQ or branch offices into our Tier III facility so internal apps never traverse the public internet.
Hybrid & remote teams
SSL VPN and WireGuard remote access with RADIUS/LDAP — give engineers secure admin access without opening SSH to the world.
From assessment to 24/7 monitoring
Assess & scope
We review your topology, compliance needs, traffic flows and existing controls — then recommend the right mix of edge, firewall and monitoring.
Design & segment
VLAN layout, firewall rulesets, VPN design and IDS/IPS profiles are documented and agreed before anything is provisioned.
Deploy & harden
Our UK engineers configure appliances, migrate rules from legacy kit and validate segmentation with you on a staging window.
Monitor & respond
24/7 NOC watches alerts, handles change requests and escalates incidents — optional fully managed rule changes included.
Explore our complete security stack
Network security works alongside edge DDoS, firewall appliances, backups and compliance — each covered in detail on its own page.
