A New Approach To Email Security

Many businesses think traditional antivirus software will protect them from an attack, but that’s simply not the case. Antivirus can stop known threats, but cyber criminals move at rapid pace, relying on the element of surprise. It can take hours or even days for antivirus vendors to identify and deploy updates to customers. 

MailGuard is different to traditional antivirus. A cloud-based email security solution, partnered with smart proprietary IP threat detection engines that predict, learn and anticipate new threats as they’re emerging. It can apply immediate protection against emerging threats for users around the globe.

Cyber security is one of the most significant issues facing businesses today, with billions of emails being sent everyday, and the rate of cyber crime increasing exponentially. Nine out of 10 enterprises report being impacted by spear phishing, and 60% of businesses who experience cybercrime are out of business within six months of the incident, with the average cost of an incident being USD $4.35 million.


Where It Started

Craig McDonald is the Chief Executive Officer and Founder of MailGuard.

In 2001, Craig founded MailGuard Pty Ltd (MailGuard), now the world’s largest private Software as a Service [SaaS] security company delivering business-to-business email security to customers throughout the world. MailGuard has agreements with some of the world’s largest providers of email mailboxes and internet security systems.

Prior to founding MailGuard, Craig was personally affected by an email containing a virus that caused havoc to his business.  Craig quickly realised how vulnerable businesses were and the extent to which email was present in our everyday lives. The experience inspired him to start MailGuard.

Craig’s key focus is to support and educate businesses who continue to struggle with cybersecurity.
