It defends organizations against phishing, ransomware, business email compromise and impersonation attempts. The platform operates across all stages of email communication to maintain secure delivery of legitimate messages with minimal false positives. This solution supports compliance with industry regulations while protecting against financial loss, data breaches and reputational harm.

Link protection functionality rewrites and scans URLs at time of click to block access to malicious websites. Attachment quarantine capabilities analyze incoming files in a secure sandbox environment and deliver either disarmed or converted versions to recipients. Message retraction enables administrators to remove malicious emails after delivery with full audit tracking. Internal mail filtering extends threat prevention to user-to-user messages within the organization to stop lateral phishing and business email compromise. Identity and domain impersonation protection leverages machine learning and display name filtering to detect and block spoofing attempts targeting executives or trusted domains.

Cloud-based architecture provides scalability for organizations of all sizes and integrates with popular platforms such as Microsoft Office subscriptions and Google Workspace.

Comprehensive reporting and analytics deliver visibility into email threats and security performance to inform strategy and ongoing improvement efforts. The solution supports legal and regulatory requirements by allowing the addition of compliance disclaimers to outbound messages. Fast implementation and straightforward deployment minimize disruption to existing workflows. Around the clock threat analyst support assists organizations in maintaining a strong security posture.
