Tessian Cloud Email Security intelligently prevents advanced email threats and protects against data loss, to strengthen email security and build smarter security cultures in modern enterprises.
Today, a comprehensive email security strategy needs to do more more than just secure an organization’s own email platform and users. Why? Because more and more often, bad actors are gaining access to the email accounts of trusted senders (suppliers, customers, and other third-parties) to breach a target company.
This is called account takeover (ATO) and one in seven organizations have experienced this kind of attack.
And, since legitimate business email accounts are used to carry out these attacks, it is one of the most difficult impersonation attacks to detect, making most organizations vulnerable to ATO.
But, not Tessian customers. Tessian Defender can now detect and prevent ATO.
Unlike Secure Email Gateways (SEGs) – which rely almost exclusively on domain authentication and payload inspection – Tessian Defender uses machine learning (ML), anomaly detection, behavioral analysis, and natural language processing (NLP) to detect a variety of ATO signals:
Importantly, Tessian’s ML algorithm gets smarter as it continuously analyzes email communications across its global network. This way, it can build profiles of organizations (and their employees) to understand what “normal” email communications look like at a granular level.
This allows Tessian Defender to catch even the most subtle ATO attacks.
Once it detects a threat, Tessian alerts employees and admins that an email might be unsafe. The warnings are written in easy-to-understand language and explain why an email has been flagged, which prevents the users from responding to the email or clicking on malicious links or attachments. These warnings also act as in-the-moment training and help improve email behavior over time.
Administrators get real-time alerts of ATO and can track events in the Human Layer Security Intelligence portal.

The consequences of ATO are far-reaching.
Attackers could gain access to credentials, employee data, and computer data. They could initiate fraudulent wire transfers, conduct bank fraud, and sell data. That means organizations could suffer significant financial loss, reputational damage, and lose customers (and their trust). And this doesn’t even account for lost productivity, data loss, or regulatory fines.
Between 2013 and 2015, Facebook and Google were scammed out of $121 million after a hacker impersonated a trusted vendor. And that’s just one example.
Tessian’s ATO threat protection minimizes these risks by preventing successful attacks.
But, detecting and preventing threats is just one of the benefits of Tessian.
