About Agari Email Security Company: Protection from Email Attacks

About Agari

Giving You the Confidence to Open, Click, and Trust Everything in Your Inbox

Our Story

Agari was founded by the thought leaders behind Cisco’s IronPort solution and co-founders of the DMARC standard for email authentication. Using predictive AI informed by global intelligence from around 2 trillion emails annually, we protect organizations against phishing, business email compromise (BEC) scams and other advanced email threats.

Email remains the most common channel for threat actors to infiltrate businesses and gain access to sensitive data and IP. Recognizing that our cloud solutions offer the gold-standard in protection against email-based cybercrime, HelpSystems acquired Agari to enhance its data security portfolio. HelpSystems works with customers to harden security across all aspects of the IT environment. The addition of Agari means that its customers can confidently trust their email inboxes, safe in the knowledge their valuable data is well protected.
