Heimdal Email Fraud Prevention
Stops phishing, BEC and impersonation attempts before they reach users.
"For organisations that need to reduce email fraud risk and protect financial workflows."
Detect and block fraudulent, spoofed and impersonation emails
Email-based fraud and impersonation remain primary vectors for financial loss and credential theft. Targeted attacks such as BEC and CEO fraud exploit routine communication patterns and altered invoices. Many organisations lack the telemetry or rules to detect subtle anomalies until after a loss occurs.
Where Heimdal Email Fraud Prevention is used
Prevent business email compromise and CEO fraud by detecting out-of-character senders, altered invoices and requests for urgent funds. Heimdal identifies phraseology shifts, IBAN and account-number changes, and attachment tampering to flag financial scams.
Supplement existing mail filtering to catch threats those systems miss. The product inspects inbound and outbound mail, scans retroactively for past threats and integrates with invoicing systems where present to detect manipulated documents.
Fits within these solutions
Delivery & deployment
Suitable environments
Designed to work with Microsoft 365 (Exchange Online), Google mail and third-party mail filters, Heimdal sits alongside existing protections to add AI-driven anomaly detection and live threat intelligence. It is suitable where mail hygiene is already in place but tailored fraud detection is needed.
It fits SMEs and regulated organisations that rely on email for authorising transactions or serving customers. It is relevant for remote or hybrid workforces, high-volume customer-facing teams and organisations handling sensitive personal or financial data.
