Security across all of it
CBT Shield, testing. CBT Sentinel, monitoring. Early access.



Attackers target small and mid-size businesses because they rarely have a security team. CBT Defense gives them one: Shield to find and fix weaknesses, Sentinel to watch around the clock. No single tool makes a business untouchable; layers of protection make it a hard target.
Tests your applications, code and AI systems the way an attacker would, then tells you exactly what to fix.
Keeps watch over your systems day and night and raises the alarm before a small problem becomes a costly one.
Four rules shape every system we deliver, whatever the industry.
We design and build software around each client's own operation: their workflow, their documents and their people. The software fits the business, so the business never has to bend to the software.
We build on established, industry-standard infrastructure and spend our engineering on the part that makes your business different.
Every system ships with access by role and a security review on every release, and can be backed by our own security products.
The team that engineered your system supports it. Questions and changes go straight to the people who know it best.
