About MailGuard

The MailGuard Group was founded in Australia 2001 to address the growing online security concerns of business. Recognising that organisations needed a simple and inexpensive way to manage unwanted email and web content, we pioneered a range of cloud security solutions to provide complete protection against online threats such as malware, spyware, viruses and spam.
Today, we’ve built a reputation as one of Australia's best technological innovators and become the trusted name in enterprise cloud security with a rapidly expanding suite of products and services. From our origins in email security, we now offer email hosting, filtering, continuity and archiving, as well as website filtering and monitoring and internally developed Salesforce.com apps, CCRM and isayso
