The World’s #1 Email Security Solution
Giving You the Facts in Seconds to Respond at the Speed of Deception

The reality is there is no magic solution to prevent 100% of phishing attacks, unless you remove email as a communication channel, or quarantine all emails. Neither of these scenarios allow for your organization to achieve operational efficiency. GreatHorn Cloud Email Security Platform changes the way you manage risk for your organization, layering sophisticated detection of polymorphic phishing threats with user engagement and integrated incident response, allowing your organization to address advanced threats at the moment risk enters your environment.

Reshaping Cloud Email Security to Address Today’s Risks

Legacy, email security vendors, with known good/known bad approaches, originally performed well when organizations had on-premise email platforms.  As organizations have shifted to cloud email platforms (G-Suite and o365),  and phishing attacks have evolved to include zero-day attacks and increasingly complex social engineering tactics, a multi-layered approach to more effectively respond to risk across each stage of the entire email lifecycle is required.

Built on the Cloud, For the Cloud

No changes to mail routing or MX records, 5 minute deployment, and out-of-the-box default policies give you the immediate protection you require.
