Complements, not replacements

Purview, Copilot, Entra, Defender, Sentinel, Splunk, SailPoint, CyberArk, Veeam - excellent tools, each built for its own question. 1Security adds the one none of them was designed to answer: who can reach what in Microsoft 365, and what did they actually do. These pages show how each pairing works.
The Microsoft stack
Built on Microsoft. Built for Microsoft.
Seven pairings with the platform you already run.
Microsoft Purview
Purview knows what your data is. The permission graph shows who can reach it - labels and access, resolved together.
How the pairing works →Microsoft 365 Copilot
Copilot inherits every permission you ever granted. 1Security shows what it inherited - before the licences go out.
How the pairing works →Microsoft Entra Suite
The Suite secures the way in. 1Security maps what is inside - every file, mailbox and agent a permitted identity can reach.
How the pairing works →Microsoft Entra ID Governance
Governance decides who should have access. 1Security watches what granted access actually does inside the tenant.
How the pairing works →Microsoft Defender XDR
Defender stops the attack in motion. 1Security shrinks what the next one can reach.
How the pairing works →Microsoft Defender for Cloud Apps
Defender for Cloud Apps governs the session and the app. 1Security resolves the permissions behind them.
How the pairing works →Microsoft Sentinel
Sentinel holds the record. The permission graph turns a suspicious login into a blast radius in minutes.

The wider stack
The tools around the tenant.
Five more pairings - SIEM, identity, privileged access and backup.
Splunk
The index and the map - Splunk stores every event; 1Security explains what the actor behind them could reach.
How the pairing works →SailPoint
SailPoint decides who should have access across the enterprise. 1Security shows what that access does in Microsoft 365.
How the pairing works →One Identity Active Roles
Active Roles gets the grant right in AD and Entra. 1Security watches the granted estate live.
How the pairing works →CyberArk
The keys above, the doors below - CyberArk vaults privileged access; 1Security maps the collaboration layer beneath it.
How the pairing works →Veeam
Veeam restores the data. 1Security answers for the access - before, during and after the incident.
