About us

A French-first, Canadian-owned, architect-led security firm

IT Sincennes Inc. helps organizations in Ottawa, Gatineau and across Canada secure their systems and get the most from their IT — in French or English, working directly with Patrick Sincennes, the Microsoft-certified architect who does the work.

Who we are

Security first, without the jargon

We start by measuring risk — not by selling products. A clear assessment surfaces what’s exposed and what matters most; then we put the rules in place and deploy the protections that stop threats. From strategy to day-to-day managed IT, we cover the whole cycle.

  • Assessment first. We measure risk before anything else.
  • Bilingual. Full service in French and English.
  • Local. A National Capital Region firm.
  • End to end. From strategy through to operations.

Proof, not just advice

We don’t just advise on security — we build it

The same expertise behind our services runs Cactus Security: our own production security tooling, built, operated and given away free by IT Sincennes. Plenty of firms only advise; we build it and run it ourselves.
