Adaptive Threat Detection - GreatHorn

Adaptive Threat Detection

Beyond Threat Intel

Legacy email security fails to catch all threats—threat intelligence alone isn’t enough.

Adaptive Analytics 

Sophisticated phishing needs intelligent detection—take a more proactive approach.

Community Intelligence 

GreatHorn strengthens industry threat intelligence with community data.

Threat Intelligence Alone Isn’t Enough

Legacy email security products rely on outdated, inaccurate, and inadequate threat detection models that put your organization at risk.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

Detect Every Type of Threat

GreatHorn automatically and continuously analyzing hundreds of data points – using data science, machine learning techniques, technical analysis, as well as threat intelligence and community threat data – clearly marking the risk factors any given email poses.

GreatHorn’s dynamic threat detection recognizes all types of email-borne threats—widespread malware, emergent attack patterns, and highly targeted phishing attempts—by employing a combination of threat detection techniques that can’t be replicated by legacy email security solutions.

Adaptive Threat Analytics

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.

GreatHorn’s proprietary risk and reputation analysis expands threat detection beyond known malicious threats to include highly suspicious emails based on multiple vectors, keeping your organization and employees safer than ever before.

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

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

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

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

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

Community Threat Intelligence

Traditional malware, zero-day threats, links to recently compromised sites with otherwise good reputations, or links that are only active for a small window of time remain a challenge, despite existing email security tools.

GreatHorn’s Community Threat Intelligence combines traditional threat intelligence with our own active data set to identify risks before they can do damage. 

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 Reporter

THREAT INTELLIGENCE: Malicious URL and malicious file detection using both third-party and proprietary threat intelligence sources

Stop Business Email Compromise Attacks with Full Lifecycle Email Security

– Webinar on Demand

Email security requires a more holistic approach to guard against business email compromise, impersonations, and credential theft attacks. In this webinar, security expert Paul Roberts of Security Ledger and GreatHorn CEO Kevin O’Brien discuss the limits of awareness training, how to make it more effective, the importance of integrated incident response, and why “100% prevention” should be a red flag.

The Myth of 100% Threat Prevention

Based on data from millions of analyzed threat vectors, GreatHorn identifies malware, malicious links, and real-world phishing attacks more rapidly and accurately than any other solution, particularly those that combine social engineering techniques with email spoofing.

But we all know that vendors who claim 100% detection/prevention will not be able to live up to this promise. At GreatHorn, we’ll prevent more threats from reaching your inbox, but we’ll also provide a layered defense strategy with End User Protection and Integrated Incident Response—to ensure that you are fully protected throughout the email lifecycle.
