Don’t Rely on Good/Bad – Detect Every Type of Threat

Legacy email security products rely on outdated, inaccurate, and inadequate threat detection models that put your organization at risk. Simple good/bad techniques struggle to identify more advanced threats such as business email compromise, impersonation, brand lookalikes, and advanced business service spoofing attacks.

GreatHorn’s Adaptive Threat Analytics uses machine learning and data science to quickly and automatically learn the legitimate communication patterns specific to each sender and recipient, making it easy to spot the anomalous emails, attachments, and links that typify suspicious content.

N

Relationship Strength

Strength of a sender’s individual relationship to the recipient, as well as a “friends of friends” system that accounts for the sender’s overall relationship with others in the recipient’s organization.

N

Spoofing Likelihood

Analysis for employee display name spoofs, domain spoofs, and domain look-alikes, including comparison against known email addresses, executive impersonation tactics, and email authentication standards.

N

Technical Fingerprint

Sophisticated analysis of domain reputation, sending IP, and header information, including determining variations in expected authentication results for DMARC, DKIM, and SPF.

N

Content Analysis

Deep content inspection based on keywords, regular expressions (RegEx), attachments, and URLs, to identify common spear phishing tactics—wire transfer and W2 requests, credential theft attacks, business service impersonations—all without storing the content or the mail.

N

Communication Patterns

Establishes an understanding of communication patterns unique to a specific individual and a specific organization, such as email frequency, volume, recipients, sending patterns and more.

Because Every Second Counts

Detect challenging threats, such as: ​

  • Zero-day threats​
  • Links to recently compromised sites with good reputations​
  • Links that are only active for a small window of time

Zero-Day Threat Identification

Identification of emerging threat patterns using data from millions of emails within the GreatHorn community — typically more quickly than traditional threat intelligence feeds

Community Threat Data

Community-sourced data on new and existing threats based both on automated collection and analysis of threat patterns and on proactive reports from GreatHorn Mailbox Intelligence

Threat Intelligence

Malicious URL and milicious file detection using both third-party and proprietary threat intelligence sources

DevOps Company Strengthens Security Resilience

“We’ve gone from an initial turnaround time of 48 hours at best to detect and respond to business email compromise to having instant alerts on our phones and desktops, catching the events in near real-time and preventing them from escalating. Using GreatHorn, we can now mitigate phishing attacks in five or so minutes.”
