Heimdal Email Security is the email assurance your remote and on-premises workforce needs. Every email is scanned for impersonation, data leak risks, and more. File attachments are scanned by default and blocked if the contents are marked as suspicious.
Mail attachments sent from outside of your company can hold many dangers. Email Security’s deep attachment scanner ensures that no malicious code makes it inside your workstation.
Complete email-based report for your reporting, compliance, and auditing requirements. Events classified as incidents are fully logged and can be reviewed from your Heimdal Unified Dashboard.
Proven Content Filters
To send an encrypted email, your employees simply create a message and hit ‘send'. Our content filters take care of the rest.
Transparent Delivery
When your employees receive an encrypted reply, the experience is just as easy. They simply open the encrypted email like regular email. No matter where they are or what device they use, if your customers and partners have email, they can easily receive encrypted email.
Convenient Recipient Experience
Our patented Best Method of Delivery ensures all messages are delivered in the most secure and easy manner possible, including transparent, pull and push methods. For pull delivery, secure web portals can be in the cloud or on-site. Also among our robust methods is secure PDF for statement delivery.
Simplified Quarantined Messages
If an email is quarantined, then employees, managers and IT receive notification to view the message and policy violations and can delete the email, or justify and release it for delivery.
We monitor all Email Security reviews to prevent fraudulent reviews and keep review quality high. We do not post reviews by company employees or direct competitors. We validate each review for authenticity via cross-reference with LinkedIn, and personal follow-up with the reviewer when necessary.
