Your tenant is more
exposed than you think.

AI can index, summarize and resurface any file a user can technically reach. Every stale share, every orphaned guest, every broken inheritance becomes a discoverable answer. AstraSecure finds those exposure paths, alerts the right owner, and remediates before a prompt ever finds them.

What AstraSecure does

Governance built for the AI era.

One platform that watches every permission, learns what's risky, and either tells the owner or fixes it itself quietly, continuously, and at tenant scale.

Full permission visibility

Every site, library, item, sharing link, and guest mapped into a queryable SQL warehouse with unlimited history.

Real-time delta sync

A 15-minute incremental sync catches a permission change minutes after it lands without hammering Microsoft Graph.

Smart, scoped alerts

Catch "Everyone", "Everyone except external users", risky guests and anonymous links routed to the right owner, not a queue.

Owner attestation

Push scheduled or event-driven reviews to the people who actually know the data. Approve or revoke in one click.

Auto-remediation with rollback

Policy-driven enforcement with a built-in snapshot of every permission, so any change can be reversed safely.

In-product user nudges

SPFx banners warn users inside SharePoint before they hit "share" coaching becomes part of the workflow.

How it works

Discover. Detect. Decide. Done.

Four moves to take your tenant from "we hope it's fine" to provably governed.

01

Scan

Baseline every permission, link and guest into a tenant-wide map.

02

Detect

Continuous deltas highlight risky changes the moment they happen.

03

Attest

The right owner reviews with full context and one-click verdicts.

04

Remediate

Revoke, restore inheritance, or expire shares with a safe undo.

Why now

AI doesn't create the risk.
It just makes it findable.

A user-shared a sensitive HR file with "Everyone" two years ago. No one noticed. Today, a single AI prompt "summarize the latest comp review notes" surfaces it instantly to anyone in the tenant.

AstraSecure was built for exactly this moment: when AI productivity tools turn legacy permission debt into business-impacting exposure. We harden your tenant first, so your AI rollout doesn't become an incident report.
