For IT admins · rolling Sentinel out to your organisation

If your organisation requires admin consent for new Microsoft apps, a tenant administrator can pre-authorise Sentinel for every employee with a single click. After that, everyone in your tenant can use Sign in with Microsoft without prompts.

Send this URL to your IT admin. They'll sign in, see the requested permissions (name, email, profile — read-only), and click Accept. That's the whole setup.

Four ways to start with Sentinel

Upload your CMR Manual

Sentinel scans your manual to align scenarios with your own authorities, reporting lines, and roles. Curveball injects force reference back to the manual.

Build from your industry

Build your CMR Manual with the guided wizard

New on Pro+ — answer ten sections of structured questions and finish with an editable Word document. ISO 22361 / 22301 / AS-NZS-5050 aligned, with twelve printable appendix templates (Initial Notification, Decision Log, TARP, Hot Wash and more) baked in.

From the founder

I built Sentinel because I've sat in too many boardrooms where the exercise was an annual set-piece. A thick report goes on the shelf, the Crisis Management Manual sits in a drawer, and the team finds out — in real time — how prepared they aren't. Big-spend, low-cadence preparation doesn't build muscle. Practice does.

Sentinel is the tool I wished I'd had: a way to take your Crisis Manual, your industry sector, or just a starting template, and produce a credible, standards-aligned exercise pack — one your CMT can sit and run next month, and the month after that. Practice as a habit, not an annual event.
