For businesses
Professional services
Cactus is free, for everyone, forever — no premium tier, no locked features. This page is simply about who builds it, and what we do professionally.
Cactus Security is built and operated by IT Sincennes Inc., a Canadian IT and cybersecurity firm. The same expertise behind these free tools is available directly to businesses that need more than a self-serve check. Work is delivered remotely, as scoped engagements.
What we do professionally
- Cybersecurity assessments — a practical review of your organization's security posture — what's exposed, what matters most, and a prioritized plan to fix it.
- Penetration testing — authorized, real-world testing of your systems and applications, with a clear report your team can actually act on.
- IT projects & modernization — fixed-fee projects delivered remotely and handed over documented: Microsoft 365 migrations and tenant hardening, Intune rollouts, server, network and cloud work, backup overhauls, and hardware or licensing refreshes. Projects, not monthly managed-IT plans.
Our promise stays the same
Every Cactus tool stays free, with no accounts and no upsell — you'll never see a sales pitch inside a result. This page exists for transparency: free tools are better when you know exactly who runs them.
