The custom regex pattern match for email address/body doesn't work efficiently sometimes. Review collected by and hosted on G2.com.

The data loss prevention with Tessian works very well. We had incidents where users were sending emails to the wrong email addresses. Tessian is able to see this and prompts the user to check the recipient address. Review collected by and hosted on G2.com.

We still have exchange deployed on-premises. We have not been able to use some of the advanced features Tessian offers for services like Office 365. Being able to delete an email from a user's inbox through the Tessian portal would be a nice feature to have. Review collected by and hosted on G2.com.

The faster a security professional can respond to and remediate a threat can mean all the difference in an attack. Not only is there visibility on the security front, Tessian also educates end users in the moment with their behavioral and learned knowledge of each user. The dashboarding is well created and customizable, giving the security team a clear view of the metrics that best serve their purposes. At the same time cancelling out the noise of un-needed information. Integration into Proofpoint and Microsoft was seamless and simple. The UI on the operator side is easy to understand and navigate. There are no wasted clicks in order to find the information you need. Overall, this tool is easy to use on both the technical side as well as the end user side. Prevention of email misdelivery, data exfiltration, and basic human error should be one of the most important areas in any organization's cybersecurity posture.

Without a large amount of data/users inputted some of the functions of the tool, understandably, do not perform as well as they could. Some companies do not have thousands of employees utilizing email or would be transmitting proprietary information. Exporting data is available only in PDF version, not .csv. Metrics could be more useful in a .csv for comparison and sortable. Review collected by and hosted on G2.com.

Compared with legacy email security solutions, Tessian's offering is very easy to both setup & use and performs very well against the most common email threats such as impersonation, business email compromise, phishing, malicious attachments etc. Native integration with SIEM solutions such as Splunk makes getting log events into third party systems easy.

Product is always getting more features and the Tessian team is working hard, listening to customers and implementing their requirements; despite this, some "not essential but nice to have" features such as being able to see the email body contents inside the platform itself without having to go to an external system have been only recently implemented and weren't available from the very beginning when we started using the product.
