Email Security Gateway for businesses and organizations

Prevent phishingProtect your users from the latest identity theft, password scams, ransomware and other incidents. Intercept all emails containing suspicious content or URLs. Halon Email Security Gateway manages and filters all inbound and outbound email traffic to protect organizations from email-borne threats. Implement it easy with standard settings, or adjust it to fit your exact needs, without compromises.

Inbound protection with top notch filtering

With the latest anti-virus, anti-spam and malware detection technology, that constantly updates in real-time, Halon detects the latest threats. We also block unwanted content using MIME type and extension filters. Protection against inbound malware, spam and phishing ensures that business productivity isn’t impacted by attacks through the email system.

Outbound protection with encryption

DANE transport encryption technology ensure that sensitive data cannot be viewed by outside attackers. Outbound filtering certify that outbound email complies with DLP policies. Full scriptability enable adherence of detailed requirements. Infinite scalability ensures continuous efficiency whenever the company structure may change.

No need for quarantine and hunting lost email

Stop spending hundreds of hours per year on searching for lost email in spam folders or quarantines. With reCAPTCHA Validation, a message that was classified
as spam will include a challenge in the error message that the sender receives where they can report a misclassification. The sender has to verify that they are not a robot using the Google reCAPTCHA technology after which the recipient receives an automatically generated message containing the report and can then choose to release the message or not.
