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 hands-on for businesses that need more than a self-serve check.
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 consulting & managed IT — day-to-day IT done right for small and mid-sized businesses: infrastructure, Microsoft 365, backups, and security baked in from the start.
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.
