Integrations include Microsoft Entra, Active Directory, Zapier, API access, and an MCP Connector; data export supports Amazon S3 and Splunk. API access is included in all plans, with rate limits but no overall usage cap. Core includes protective DNS and content filtering, 90-day report retention, and 9-day query log retention.
