Scalio Nexus is a cloud-native SaaS platform designed to bring clarity and control to your Microsoft Entra estate. By connecting directly to Microsoft Entra ID, Microsoft 365, and Azure, Nexus surfaces real-time identity posture insights, automates access reviews, and gives your team a single, authoritative view of who has access to what — and whether that access is appropriate. Built on zero-trust principles, Nexus helps organizations move from reactive identity management to proactive governance without adding infrastructure complexity. ## Who is Nexus for? Nexus is purpose-built for the teams responsible for securing and governing identity at Microsoft-powered enterprises. * **IT administrators managing Entra ID** — Whether you're onboarding new employees, cleaning up stale accounts, or untangling a sprawl of app registrations, Nexus gives you a structured, searchable view of your entire directory. You get actionable signals instead of raw data. * **Security teams needing posture visibility** — Nexus continuously evaluates your Entra configuration against zero-trust best practices and highlights misconfigurations, over-privileged identities, and risky service principals before they become incidents. Real-time posture scoring means your team always knows where you stand. * **Compliance officers running access reviews** — Nexus makes periodic access reviews auditable and defensible. You can launch reviews on a schedule, assign reviewers, track completion, and export results — all from a single interface that maintains a clear evidence trail for audits. ## Core capabilities A unified view of every user, group, service principal, and application in your Entra estate — with risk signals and change history surfaced in one place. Schedule and manage periodic access reviews for groups, roles, and application assignments. Assign reviewers, track progress, and produce audit-ready reports automatically. Define lifecycle policies that automatically revoke stale access, flag anomalous assignments, and enforce least-privilege rules across your directory — without manual intervention. Continuously scored posture checks mapped to zero-trust principles and industry frameworks. Drill into each finding to understand the risk, see affected objects, and follow guided remediation steps. ## Key benefits * **Single pane of glass.** Nexus consolidates identity and access data from Entra ID, Microsoft 365, and Azure into one platform, eliminating the need to cross-reference the Entra portal, PowerShell exports, and spreadsheets to answer basic governance questions. * **Reduce manual review burden.** Automated access reviews, approval workflows, and lifecycle policies cut the time your team spends on recurring governance tasks — freeing IT and security staff to focus on higher-value work. * **Catch misconfigurations before they become breaches.** Nexus runs continuous posture checks against your live tenant configuration and alerts your team to issues like legacy authentication enabled, admin accounts without MFA, or applications with excessive API permissions. * **Zero-trust aligned, out of the box.** Every Nexus capability is designed around zero-trust principles — verify explicitly, use least-privilege access, and assume breach. Posture scoring, access controls, and review workflows all reinforce the same model your security strategy is built on. ## How Nexus connects to your environment Nexus integrates with your Microsoft tenant entirely through Microsoft's standard OAuth 2.0 delegated admin consent flow. When you connect a tenant, Nexus requests a defined set of read-only Microsoft Graph API permissions. A Global Administrator or Privileged Role Administrator approves the consent grant once, and Nexus begins reading identity and access data — users, groups, roles, applications, audit logs — directly from the Microsoft Graph. There are no agents to install, no network changes to make, and no data to export manually. Nexus operates as a trusted application registered in your tenant, and all data in transit is encrypted. You can review and revoke the consent grant from your Entra portal at any time. Ready to get connected? Follow the [Quickstart](/nexus/quickstart) to link your Entra tenant in minutes.
