Heimdal Email Fraud Prevention
Stops spoofed and fraudulent emails before they reach users.
Detect and block spoofed and fraudulent email with Heimdal Email Fraud Prevention
Email remains a primary route for phishing and business email compromise. Spoofed senders and impersonation can bypass basic filters and land in inboxes used for approvals and customer contact.
Heimdal Email Fraud Prevention identifies spoofing and fraudulent indicators, blocks or quarantines suspicious messages and applies policy controls to reduce user exposure. It provides clearer signals for allowlists, blocks and automated quarantines so teams spend less time triaging suspect mail.
Where organisations authorise transactions by email or operate with remote staff, reducing email-borne fraud reduces operational risk. The product complements Exchange Online protections and can sit alongside other mail controls in a mixed estate.
Where Heimdal Email Fraud Prevention is used
Protecting SME Exchange Online estates that handle high volumes of customer email. Heimdal is used to filter BEC attempts and impersonation of senior staff so fewer fraudulent messages reach inboxes.
Applying stricter controls for regulated teams handling personal or financial data. Policies and quarantines reduce manual review and limit risky approvals carried out by email.
Integrating message signals into existing mail routing and security tools for richer context. That helps security teams prioritise potential threats without adding a managed monitoring layer.
Suitable environments
Fits small and mid-sized organisations using Microsoft 365 (Exchange Online) or mixed cloud email where email is a primary trust channel. Works well for teams that want stronger email controls without a full-time security operations function.
Most useful where staff approve payments or share sensitive data by email, or where customer-facing teams handle many inbound messages. It complements existing mail hygiene rather than replacing core Exchange protections.
