A good IT partner brings the tools, the monitoring, and the expertise. What they can't do is decide who in your company should have access to payroll. They can't stop someone from approving a convincing fake invoice at 4:45 on a Friday.
The 2026 Verizon Data Breach Investigations Report found that 62% of breaches involved a human element, and third parties were involved in 48%.¹ Both numbers point to the same place: protection lives in the handoffs between people, policies, and partners.
So the better question isn't "Is our provider handling security?" It's "Do we know who owns what?"
Three ways to find out this week:
- Ask your provider for a written responsibility matrix: what they own, what you own, and what's shared
- Confirm who approves access changes when someone joins, changes roles, or leaves
- Check when your team last had security awareness training, and whether it stuck
In Sentry's Technology Maturity Model (TMM), this is the heart of the Secure stage. Clear ownership matters more than another tool.
