Frequently asked questions
Everything you need to know about the product and billing.
What makes 1Security different from Microsoft Entra ID (Azure AD)?
Microsoft provides basic identity and access controls, but lacks real visibility into who actually has access to which files, sites, and data. 1Security fills this gap with a detailed, user-friendly map of permissions across Microsoft 365, including sensitive data locations and historical changes so you can govern AI and human access confidently.
Can 1Security replace our existing DLP or compliance tools?
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.
Can 1Security track external guest access across the inventory?
Yes. Guest accounts and external users are visible in the unified inventory, so you can see who still has access and remove them if needed.
Can it track historical audit data?
Yes. 1Security retains audit logs with timestamps and tracks key changes such as group membership, sharing link creation, and permission state history — with time-stamped records for audits.
Can it support AI readiness assessments?
Yes. 1Security analyzes permissions, labels, and exposure paths to verify controls and identify risks for safe Copilot adoption. It identifies data security risks and creates actionable recommendations so your organization can adopt Copilot safely and meet privacy standards set by the European Union.
Can non-technical stakeholders use it?
Yes. Plain-language reports and read-only views make it easy for compliance, legal, and business stakeholders to see the evidence behind findings without needing admin rights.
Does it support Microsoft Copilot readiness?
Yes. 1Security’s audit features reveal sensitive data and oversharing that could be exposed by Copilot, ensuring labels, access boundaries, and policies are aligned before rollout.
Does 1Security integrate with advanced security features like privileged identity management and conditional access policies?
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.
Do you support ISO 27001, SOC 2, HIPAA, and GDPR work?
Yes. 1Security maps findings and evidence to common control frameworks, helping organizations demonstrate compliance more efficiently.
