A new approach to email and web security

Most businesses think their 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 and web solution, partnered with smart Hybrid AI threat detection engines that predict, learn and anticipate new threats as they’re emerging. This cloud-based layer of security means MailGuard can apply immediate protection against emerging threats, to users across 27 countries around the globe.

Cyber security is one of the most significant issues facing businesses today, with millions of emails being sent everyday, and the rate of cyber crime increasing by 270% in 2015. 9 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 AUD$276,323.

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 and web security to customers in 27 countries. MailGuard has agreements with some of the world’s largest providers of email mailboxes and internet security systems.

In 2001, Craig was personally affected by an email containing a virus that caused havoc to his business.  Craig quickly realized 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 IT security. With only 30% of global businesses making the shift to the cloud, Craig sees this as an enormous opportunity.
