Best for: Regulated mid-market teams that want endpoint-level visibility, in-the-moment coaching, and a self-serve 30-day trial.

2

Nightfall AI

AI-native DLP platform with a mature ML detector library, broad SaaS API connectors (Slack, M365, Drive, Salesforce), a browser plugin, and lightweight endpoint agents.

Best for: Teams that want a DLP-first platform across SaaS surfaces, with Okta and SCIM provisioning and AI coverage added on top.

Best for: Teams whose primary need is sensitive-data scanning at rest inside SaaS collaboration apps.

5

Polymer

Agentless, API-integrated DLP for SaaS collaboration apps (Slack, Teams, Google Workspace, GitHub, ChatGPT) with NLP-based redaction.

Best for: Small, Mac-heavy teams that want fast agentless SaaS DLP coverage with a low entry price.

Best for: Microsoft-365-centric enterprises standardising on the Purview compliance stack.

Where Aona is weaker

We carry these caveats verbatim from our own Aona vs Nightfall AI comparison. An honest alternatives list has to include where the leader falls short.

  • !Smaller ML detector library than Nightfall. Multi-year detector refinement is genuinely on their side.
  • !No SaaS API connectors today (Slack, M365, Drive, Salesforce). Nightfall ships these as standard.
  • !Microsoft Entra only for SSO. No Okta-native, no SCIM auto-provisioning.
  • !Pre-revenue with two pilots. Nightfall has hundreds of paying customers and a 4.4-star Gartner Peer Insights presence.
