Managed Security & Infrastructure

We keep your infrastructure secure, online, and watched 24/7.

CNET designs, hardens and monitors the systems your business runs on — firewalls, email, DNS, servers and backups — so threats are blocked and problems are caught before they bite.

What we do

End-to-end protection for every layer

From the network edge to the mailbox, we secure and operate the infrastructure that keeps your organisation running.

Managed Firewalls

FortiGate deployment, tuning and 24/7 oversight — segmentation, IPS, VPN and policy management that actually keeps attackers out.

Email Security & Anti-Spoofing

SPF, DKIM and DMARC done right — enforced policies, aggregate-report monitoring and dashboards that stop your domain being impersonated.

DNS & DNSSEC

Redundant, authoritative DNS with secondary servers and DNSSEC signing — resilient resolution that stays up when others fall over.

Infrastructure Monitoring

Real-time metrics, certificate-expiry tracking and proactive alerting — we see the disk filling or the cert expiring before you do.

Virtualization & Backup

VMware/ESXi operations plus tested, off-site backups and disaster-recovery planning — so an incident is a hiccup, not a catastrophe.

Secure Hosting & SSL

Hardened web & mail hosting with automated Let's Encrypt certificates and continuous patching — secure by default, hands-off for you.

Why CNET

Security that's operated, not just installed

Tools don't protect you — disciplined operations do. That's what we bring.

Defence in depth

Layered controls across network, email, DNS and host — no single point of failure.

Proactive, not reactive

Continuous monitoring and alerting catches issues before they become outages.

Always watching

24/7 visibility into uptime, certificates and capacity across your estate.

Greek & on-call

Local expertise that knows your environment and responds when it matters.
