Your data risk grew
faster than your team.
- Sensitive data is scattered across files, email, and apps, and no one can say exactly where it lives or who can reach it.
- Audits, customer security reviews, and new regulations keep landing, but you don't have a dedicated team to answer them.
- You want to adopt Copilot and AI tools, but oversharing and loose permissions make that genuinely risky today.
A running program, not a one off project.
Four things we do continuously inside your Microsoft 365 tenant.
Discover
Find and classify sensitive data across your tenant, and map who can reach it.
Govern
Right-size permissions, kill risky sharing, and put policy and DLP in place.
Prove
Keep controls and evidence current so you're always audit-ready.
Adopt AI
Fix the risks that make AI unsafe so you can turn on Copilot with confidence.
