Prevent Inbound Email Attacks that bypass SEGs

Inbound Email Security

Tessian Defender is a comprehensive inbound email security solution that automatically prevents a wide range of attacks that bypass Secure Email Gateways, while providing in-the-moment training to drive employees toward secure email behaviour.

Threat Prevention

Defender protects against both known and unknown email attacks, including Business Email Compromise (BEC), Account Takeover (ATO), spear phishing, and all impersonation attacks that bypass Secure Email Gateways, Microsoft 365, and G Suite.

Education and Awareness

With Defender’s in-the-moment training, organisations can educate and empower users to build continuous email security awareness.

Reduce Admin Overhead

Defender removes the burden on the SOC and admins by automating repetitive tasks such as maintaining triage and review. This eliminates the need for human verification of email threats, reducing FTE requirements.

How it works

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:

  • Account Takeover
  • Business Email Compromise (BEC)
  • All Impersonation Attacks
  • Spear Phishing
  • Social Engineering
  • Whaling Attacks

Prevent Misdirected Emails

Tessian Guardian is the industry’s first and only solution that automatically prevents accidental data loss from misdirected emails and misattached files (sending the wrong attachments over email).

Powered by Tessian’s proprietary Human Layer Security Engine, Guardian compares millions of data points for every outbound email and detects anomalies that indicate whether the email is being sent to the wrong person or if a wrong document is being attached.

Unlike security controls that provide unintelligent and repetitive pop-up notifications which cause alert fatigue, Guardian only shows warning notifications to employees when anomalies are detected. Tessian Guardian keeps notification rates low and provides contextual information that reinforces security awareness and data protection policies through in-the-moment training.

Key Benefits of Tessian Guardian

  • Automatic protection using machine learning. No predefined rules required
  • Prevent accidental data loss from misdirected emails, which are impossible-to-detect with legacy DLP controls
  • Stop emails with incorrect attachments that can expose classified and sensitive commercial data to unintended recipients
  • Safeguard your intellectual property, comply with customer confidentiality
    agreements, and eliminate the risk of reputational damage
  • Meet GDPR, CCPA, HIPAA, and other mandatory data protection regulations
  • No behaviour change required for employees; minimal end user disruption and zero admin for security teams
  • Reinforce security awareness and data protection policies through in-the-moment training

New Research: Spear Phishing Threat Landscape Report 2021

Native tools do a good job protecting users against bulk phishing attacks and spam, but can’t detect more sophisticated spear phishing and social engineering attacks. Phishing awareness programs help, but still leave people as the last line of defense and – as we all know – to err is human. 

To help you understand the risk, we analyzed nearly 2 million emails flagged by Tessian Defender as malicious to identify the what, how, who, why, and when of today’s spear phishing landscape.
