History of MailGuard

MailGuard was founded in 2001 as the response to businesses seeking a simple and inexpensive solution that would conquer the constant flow of unwanted, unsolicited and potentially malicious email content. Recognising the demand for constant and reliable protection, MailGuard pioneered our cutting-edge range of cloud security solutions.

For contemporary companies, email communication is a fundamental and essential part of business functions, development and future prosperity. Highly evolved email and web-borne threats are ever present. In order to remain protected from potential threats such as hacking, malware, phishing scams, spam and cyber fraud, all companies must be proactive in monitoring their mail 24/7. MailGuard dramatically increases clients’ productivity by automating multi-layer security at the internet level before impacting our clients’ infrastructure and their staff inboxes.

MailGuard is the solution to this problem that affects businesses globally. Threats that could potentially ruin reputations and destroy livelihoods.
