Ironscales Email Protect is an integrated cloud email security platform that uses an API-based architecture to defend against advanced threats like business email compromise, ransomware, and credential harvesting. The software employs adaptive AI and anomaly detection at the mailbox level to identify and remediate malicious emails in real time. It uniquely integrates human intelligence by crowdsourcing threat data from its global user community and incorporating phishing simulation testing to improve employee awareness. The solution integrates directly with Microsoft 365 and Google Workspace, requiring no changes to MX records or gateway configurations.

Proofpoint Core Email Protection is a security platform that filters inbound and outbound email to identify and block threats such as phishing, malware, and business email compromise. The system utilizes machine learning and behavioral analysis to inspect message headers, content, and attachments for anomalies and malicious intent. It provides flexible deployment options through either an API-based integration or a secure email gateway to monitor internal and external communications. Additionally, the software includes automated quarantine and remediation features to remove harmful messages from user inboxes after delivery.

Abnormal Cloud Email Security is an AI-native platform that utilizes a behavioral data science approach to stop advanced email attacks such as business email compromise and executive impersonation. The system integrates via API to build baseline models of normal user behavior, allowing it to identify and block messages that deviate from established patterns of communication. Beyond inbound filtering, the product includes automated account takeover protection and security posture management to detect compromised credentials and configuration risks. Because it operates through a cloud-native API architecture, it requires no gateway changes and can be deployed for Microsoft 365 and Google Workspace in a single click.
