Account Takeover Protection - GreatHorn

Protect Against Internal Threats

The risk of account takeover has increased exponentially. Yet identifying compromised email accounts can be tricky – often showing up only after there’s been financial and reputation damage. Implementing multi-factor authentication won’t protect users from cell-jacking, unattended and unlocked devices, or phone-based social engineering.

GreatHorn Account Takeover Protection provides a low-friction, secondary layer of authentication that’s easy to implement, difficult to bypass, and minimally disruptive for employees.

Account Takeover Protection

Use biometric authentication to verify employee identities, reducing exposure from any compromised accounts.

Credential Theft Detection

Prevent employees from accessing password-stealing accounts by using computer vision to analyze suspicious links.

Internal Email Protection

Analyze internal email the same way as external – taking into account relationships, communication patterns and more.

The Only Defense Against Account Takeover Attacks

Most solutions claiming to provide account takeover protection use behavioral cues to try to identify account takeover – but can’t actually verify the sender’s identity.

GreatHorn actually validates the identity of a sender using biometric authentication.

Simple Easy Identification – No Devices Required

Your typing pattern is automatic, always available, and unique to you. Account Takeover Protection uses machine learning techniques to capture an employee’s unique typing pattern on both desktop and mobile devices – analyzing the dynamics of an employee’s keystrokes, such as speed, pressure, and timing between key press and release. We don’t capture the keystrokes themselves.

Ongoing maintenance and support

When your business is compromised by a phishing attack, every second counts. With GreatHorn’s proactive managed email security offering, you receive GreatHorn’s technical expertise, combined with our best-in-class cloud email security solutions, optimized to the level you need to maintain the most advanced email security posture.
