Microsoft 365 permissions don’t explode—they pile up. Guests that never leave, files marked “public” by mistake, and forgotten external users that still have access. 1Security’s Access Management Tool untangles the mess, showing exactly who can see what—simple, safe, and audit-ready.
1Security helps your team work faster and safer in Microsoft 365: ready for AI, protected against breaches, audit-ready for compliance, and prepared to recover quickly from any incident.
Safely deploy Copilot and other AI assistants without risking sensitive data exposure.
Eliminate “Excel-driven” manual access reviews; free up IT teams for strategic tasks, with scalability to support larger organizations and their complex access needs.
Prevent unauthorized access and minimize insider threats with least privilege enforcement, enabling secure access to sensitive data across all environments.
Demonstrate control for ISO 27001, GDPR, HIPAA, SOX, and other frameworks with audit-ready reporting, supporting regulatory compliance requirements.
Use forensic analysis to understand what happened and restore permissions in minutes, not weeks.

Replace blind spots with clarity. 1Security’s Office 365 Access Management Tool shows exactly which users, apps, and external guests have access to sensitive data — giving you one source of truth for every permission in Microsoft 365.
Instantly see which users, groups, and applications have access to sensitive files, SharePoint sites, Teams, and Exchange resources.
Go beyond Purview and identify who has access to your confidential data (e.g., credit card numbers, payroll, personal data) and who can access it, be it users, apps, Copilot, or other AI agents.
Track access rights, monitor privileged permissions and requests managed through the admin center, and respond to risky behaviors.
Roll back to past permission states to investigate incidents and recover from data breaches. (soon to be released!)
Remove risky external links, enforce expiration of guest accounts, manage external access and guest user permissions, and enforce conditional access for both internal and external access scenarios to streamline permission management.
Ensure Microsoft Copilot and third-party apps only see the data they should, preventing unintended leaks.

Everything you need to know about the product.
Microsoft provides basic identity and access controls, but lacks real visibility into who actually has access to which files, sites, and apps. 1Security fills this gap with a detailed, user-friendly map of permissions. It also complements IAM solutions like Azure Active Directory by supporting unified identity management across cloud environments, helping organizations control access and manage digital identities more effectively.
No – it complements them. Tools like Microsoft Purview or Varonis protect data but require you to guess what should be protected. 1Security shows you where sensitive data is and who has access before you set policies. It also enhances your access management IAM strategy by providing visibility into digital identities and supporting regulatory compliance requirements.
Most teams are onboarded within days. You can start with a demo environment, then connect your Microsoft 365 tenant securely to see access insights immediately. As part of onboarding, you can connect your Azure AD tenant, support hybrid identity scenarios with on premises Active Directory, and integrate with your on premises directory or Azure resources.
1Security supports a wide range of identity types, including user, device, application, and hybrid identities. It integrates with managed identities and Microsoft Entra Workload identities, enabling secure automation and access for services and applications across your environment.
Yes. 1Security works alongside privileged identity management (PIM), conditional access policies, and access policies in Microsoft 365 and Azure AD. It provides visibility into privileged roles, helps enforce access policies, and supports granular control over who can access sensitive resources.
The Microsoft Entra admin center serves as a centralized platform for managing device identities, application integrations, and workload identities. Microsoft Entra Private Access enables secure connectivity to private apps and Azure resources, providing seamless network access without relying on traditional VPNs. 1Security integrates with these tools to enhance secure access management.
Yes. 1Security maps findings and evidence to common control frameworks, helping organizations demonstrate compliance more efficiently.
No. While designed for complex environments, 1Security is equally valuable for mid-sized organizations running Microsoft 365 or Office 365 that need strong visibility into access, activity, and compliance.
Stop guessing who has access to your sensitive data. With 1Security, you gain the visibility, automation, and confidence needed to protect your Microsoft 365 environment.
