Respond Faster to Advanced Threats

Lastline Defender delivers market-leading visibility and detection accuracy, enabling you to respond faster to attacks targeting your cloud mail before a data breach occurs. Your security team can respond to alerts with certainty, eliminating the need to investigate generic alerts for potential false positives.

Defeat Phishing Campaigns with Machine Learning

In order to catch the more advanced attacks, Lastline utilizes a unique machine learning algorithm that analyzes 300+ indicators in each email by looking at each email component including:

  • Headers
  • Subject
  • Body
  • Links
  • Content the links point to
  • Zero fonts

Prevent Credential Theft and Account Takeover

Lastline Defender analyzes login and account activity to block account takeover and credential theft. It correlates login events with past activity based on:

  • Geography
  • Time of day
  • Sending outgoing phishing emails
  • Sending a high volume of emails
  • Sending emails with multiple recipients

By correlating these indicators through another machine learning filter, Lastline Defender flags compromised accounts while minimizing false alerts.

Block Business Email Compromise

Business Email Compromise (BEC) attacks start with a spear-phishing attack or spoofed emails targeted at specific executives. Lastline Defender blocks BEC attacks by detecting when a similar sender exists in the organization with a different email address. It also verifies the identity of the sender by cross-referencing several fields in the email including the sender and the signature at the bottom of the email.

Deploy Proven Protection Against Advanced Threats

Lastline’s proven technology protects millions of users around the world from advanced malware attacks. The same technology that earned the highest security effectiveness rating in four consecutive NSS Labs Breach Detection Group Test protects your Microsoft Office 365 Mail users from advanced threats.


Improve Security without Complexity

Lastline Defender gives you maximum protection and low TCO. Attackers can easily fool Microsoft Office 365 Mail (even with Microsoft ATP) with a range of techniques:

  • Traditional anti-phishing techniques are inadequate to prevent BEC attacks.
  • Lack of outbound and internal email scanning misses ATO threats
  • Fileless malware attacks evade signature-based protection
