Organizations around the world now face unprecedented challenges preventing, detecting and responding to modern and more sophisticated phishing attacks, such as business email compromise (BEC) and sender impersonation. Standards like DMARC are not well adopted since they very hard to implement and are effective only against specific types of phishing attacks such as exact domain spoofing.

With more than 500 businesses being targeted per day by BEC attacks, what can businesses do to protect their inboxes from this increasing threat vector?

IronSights an Advanced Mailbox-level Anomaly Detection takes a “bottom-up approach,” using machine learning algorithms in the mailbox itself to create a fingerprint in conjunction with common past communication habits and trusted relationships to proactively combat impersonation and spoofing emails in real-time.

DMARC is not Enough! The Need for Advanced Email Authentication

The email protocol was not designed with security in mind, and there is no authentication mechanism in place whatsoever. However pseudo-authentication is now possible using ‘sender fingerprinting', an advanced machine learning based technology that can identify the true identity of a sender. This technology was designed and built to answer a simple, yet very complicated question:

Who is sending me what?

How Does IronSights Compliment DMARC and Protect Against BEC?

IronSights is an Advanced Mailbox-level Anomaly Detection module that protects company's employees from business email compromise (BEC), email spoofing and impersonations attempts by dynamically learning their mailbox and communication habits.

IronSights fingerprinting technology takes into account factors like implementation level (no/full/partial) of DMARC/SPF/DKIM, sending IPs, normal communication context and other meta data in order to create a unique fingerprint for each sender, any deviation from the norm will be detected immediately and flagged inside the mailbox through InMail banner alerts.

Using machine learning algorithms, IronSights also continuously studies every employee's inbox to detect anomalies based on both email data and metadata extracted from previously trusted communications that can then automatically flag suspicious emails to help people make smarter and quicker decisions regarding suspicious emails within the mailbox.

An employee’s inbox protected from BEC by IronSights at the mailbox level.

IronSights - Advanced BEC Protection

Recommended BEC protection, such as DMARC, is not well adopted since it is very hard to implement and is only effective at email spoofing protection when dealing with a small subset of phishing threats.
