Who we are
About Sirius Star IT
We are a hands-on IT infrastructure consultancy based in Israel, working with clients across Israel, Europe and Central Asia. Every engagement is led by the engineer who will actually operate your systems — not a sales layer between you and the work.
Our background spans bare-metal hypervisor deployments, multi-region VPN architecture, self-hosted communication platforms and production incident response — the kind of infrastructure that has to work correctly the first time, because people depend on it daily.
What we do
Services
Infrastructure engineering across the full stack — network to application.
VPN & Network Infrastructure
Design and deployment of multi-region VPN networks — WireGuard and IPsec, obfuscated transports, multiple exit points, split tunneling and smart routing for clients who need to choose exactly how their traffic leaves the network.
Virtualization & Cloud
Proxmox and KVM deployment from bare metal, storage and network design, unattended OS provisioning, and migration of existing workloads onto virtualized infrastructure with zero guesswork.
Security & Hardening
SSH and firewall hardening, protocol-level traffic diagnostics, certificate lifecycle automation, and incident response when something breaks at 2 a.m. — diagnosed and fixed, not just patched.
Mail & Collaboration Platforms
Self-hosted email (Stalwart, Postfix/Dovecot stacks), encrypted chat and video (Matrix/Element, LiveKit), deployed and maintained so you own your data instead of renting it.
Monitoring & Observability
Agentless, SSH-based monitoring across your entire fleet — load, memory, disk health, container state — with dashboards and alerting that tell you about a problem before your customers do.
Automation & DevOps
Docker Compose stacks, unattended installers, CI/CD pipelines and custom internal tooling — the automation that turns a one-off fix into a repeatable, documented process.
Why us
Why work with us
Engineering judgment, not ticket queues.
Direct engineer access
You talk to the person doing the work — no account managers relaying messages.
Multi-region experience
Production systems running across Israel, Kazakhstan, the EU and beyond.
Security-first by default
Every deployment is hardened and documented before it's called done.
Built to last
We design for the 2 a.m. incident, not just the demo.
