Business Email Compromise

Business Email Compromise Prevention: How to Overcome the Multi-Billion Dollar Threat.

Tessian can continually analyze, adapt, and evolve based on an understanding of normal and anomalous human behavior. We combine these with in-the-moment education to protect you from BEC threats.



Know Your Risks

BEC Attacks: The Number One Email Threat.


The FBI Annual Cybercrime Report showed Business Email Compromise (BEC) is 64 times worse than ransomware attacks. BEC scams caused over $1.8 billion worth of losses in 2020.


Most organizations rely on protecting their email infrastructure to stop BEC attacks. They do this by securing their domain, using DMARC, DKIM, and SPF, two-factor email authentication etc.


But such an approach has limitations as it can only protect against a small subset of BEC attacks that impersonate your own domain. BEC attacks are successful because unsuspecting email users get breached.

How Tessian stops BEC attacks with Human Layer Security:

  • Modeling User Relationships and Communication Patterns

    Unlike legacy email solutions that use a rule-based approach, sender reputation, and deny/allow lists, Tessian’s machine learning can detect the most sophisticated attacks and zero-day threats by identifying granular behavioral anomalies. When you first deploy Tessian, our machine learning algorithms analyze 12 months of historical email data to learn and understand evolving relationships within your email network.

  • Threat Benchmarks

    Tessian’s Global Threat Network, a rapidly growing database of all known spear phishing, BEC, and other targeted impersonation attacks – helps identify and prevent inbound threats before they’re ever seen in your environment.

  • Analyze the Data Layer

    Tessian analyzes email metadata in real time and identifies anomalies by comparing inbound emails with your historical email dataset and the Tessian Global Threat Network. We process billions of email data points to compare against normal email behavior and map trusted email relationships to detect the most subtle anomalies of an attack.

  • Content X-Ray

    Tessian uses natural language processing (NLP) and conducts deep content inspection to look for email content that has malicious intent.

  • Behavioral Analysis

    A 3-level behavioral analysis then identifies the most attacked person(s) in your organization, the spread of the attack, and previous instances of such an attack.

  • Contextual Employee Education

    Tessian prevents users from becoming victim to an attack by explaining what is unusual about the email with contextual warnings. This in-the-moment training helps them to detect future attacks over time.
