About Sigmateli
We are a long-term operations partner—not a project shop. Your networks, infrastructure, security, and cloud stay monitored, patched, and supported while your team focuses on the business.
Why we exist
We sit alongside your leadership or ops team—explaining what we see, agreeing scope before production changes, and staying reachable without ticket ping-pong.
Operations, not projects
SIGMATELI Limited focuses on dependable day-to-day administration: networks, infrastructure, endpoints, cloud workloads, security, and backups so your staff can stay on their work.
Clear ownership
When something needs attention, you know who is handling it. We favour direct communication—email and phone—with updates in plain language while we work.
What we run for you
Security and recoverability are part of routine operations—not a separate brochure line item.
Networks & infrastructure
LAN/WAN, firewalls, VPNs, servers, and endpoints kept patched, monitored, and documented.
Security & backups
Access policies, hardening, backup strategy, and restore practices built into daily admin.
Cloud & Microsoft 365
Tenant hygiene, identity, mail, collaboration, and hybrid workloads you can rely on.
Support you can reach
Direct email and phone contact, plain updates, and troubleshooting when something breaks.
How we work
A simple path from first conversation to long-term administration.
Discovery
We learn your setup, priorities, compliance needs, and any immediate risks or outages.
Agreed scope
We document what we run, how we access systems, escalation paths, and how you reach us.
Ongoing operations
Patching, monitoring, backups, user support, and iterative improvements as you grow.
Who we support
We do not display client logos until we have permission to share them.
Growing teams
Companies outgrowing ad-hoc fixes who need structure, monitoring, and a clear owner.
Lean IT coverage
Organisations without a full in-house department that still need enterprise-grade ops.
Single accountable partner
Leaders who want one relationship for infrastructure, cloud, and day-to-day support.
