How Defender Works

Prevent Inbound Attacks

Detect all indicators of inbound email attacks.

 

Defender’s behavioral intelligence leverages at least 12 months of historical data that includes the company’s emails, company network, as well as Tessian’s Global Threat Network, to detect all indicators of inbound email attacks. By using these broad range of signals from relationship graphs, deep inspection of the email content, and previous user behavior, Tessian can identify all inbound email attacks including:

 

Machine Learning Threat Prevention

Identify inbound email threats in real-time.

 

Tessian’s Human Layer Security (HLS) Engine analyzes all inbound emails in real-time and uses machine intelligence to automatically predict whether an incoming  email is malicious. Using a broad range of signals from relationship graphs, Tessian performs deep inspection of the email content, and previous user behavior.

 

Legacy approaches will scan for known malicious payloads such as links and attachments. This leaves these defenses vulnerable to zero-day threats, or attacks without payloads. Tessian will inspect the context of the email to determine indicators of an attack, notify the user, therefore not giving an opportunity of malware slipping through or the user to click.

 

In-The-Moment Training

In-the-Moment Training to Stop Email Attacks Where They Start

 

When unsafe emails are detected, employees can either receive in-the-moment alerts with clear, simple explanations of potential risks or emails can be directly quarantined for inspection and approval by Security Analysts.

 

  • Non-disruptive in-the-moment training and awareness is provided to employees through contextualized, easy to understand warning messages.
  • Risk trends downward as users learn more about security through in-the-moment warnings, becoming better at spotting attacks and lowering click-through rates on identified threats.
