CORE OPERATOR LTD is a UK-based IT consulting firm specialising in the design, implementation and security of enterprise networks — from firewalls and switching to server infrastructure and 24/7 cyber defence.
Vendor-agnostic engineering across the full networking and security stack — designed, deployed and supported by certified professionals.
From greenfield builds to brownfield upgrades — we design networks that are fast, segmented and ready to scale.
Next-gen firewalls deployed and tuned for your traffic patterns, compliance needs and threat landscape.
Enterprise-grade Layer 2/3 deployments with PoE, stacking and full visibility into every port.
Physical, virtualised or hybrid — we build server stacks that just work, with backup and DR built in.
Proactive defence — from perimeter hardening and endpoint protection to incident response and audits.
Independent advice on architecture, vendor selection, migration roadmaps and IT governance.
We're the team you bring in when "it works" isn't enough — when you need infrastructure that's documented, defensible and built to last.
Companies House registered (No. 15631238) — fully compliant, GDPR-aware and accountable.
We pick the right tool for the job — Cisco, Fortinet, Palo Alto, Microsoft, Ubiquiti, MikroTik and more.
Discovery, design, procurement, install, documentation, handover, ongoing support — one team, one phone call.
Reactive break-fix, proactive monitoring or fully managed contracts — choose the model that fits.
No surprises, no scope creep — just a defined path from first conversation to live infrastructure.
Discovery sessions, audit of existing infrastructure, gap analysis against your goals.
Architecture diagrams, vendor recommendations, BoM and a fixed-scope statement of work.
Configuration, deployment and migration — executed in change windows that minimise downtime.
Handover documentation, knowledge transfer and ongoing managed support if you need it.
CORE OPERATOR LTD was founded to bring genuine engineering rigour to small and mid-sized businesses that have outgrown break-fix IT but don't need an in-house infrastructure team.
We work as a trusted technical partner — translating business requirements into resilient, secure and well-documented network and server infrastructure. No reseller agendas, no one-size-fits-all packages.
Tell us what you're trying to achieve. We'll come back with practical next steps within one business day.
Whether you need a one-off audit, a full network refresh or ongoing managed support, we'd be glad to hear what you're working on.
