Multiple Data Connector Security Fixes: Trend Micro Authentication and MongoDB Atlas Expansion

What Changed

Mixed connector maintenance addressing authentication vulnerabilities, regional deployment expansion, and dependency updates across four enterprise security solutions.

Security Impact (Visibility & Fidelity)

Trend Micro Vision One: DefaultAzureCredential replaced with ManagedIdentityCredential — the original implementation potentially exposed authentication tokens or caused ingestion failures in managed identity environments. Deployments using DefaultAzureCredential may have experienced authentication-related data loss.

MongoDB Atlas: Added UK site configuration and removed UAE site support — organisations with UK-based MongoDB deployments gain new log visibility, while UAE deployments lose connector support. Enhanced filtering logic for ACCESS/NETWORK/QUERY log categories improves data fidelity.

Varonis SaaS: State management improvements and alert object mapper fixes address potential data synchronisation gaps that could cause missed security events.
