MailGuard, a GlobalGuard company founded in 2001, is a cloud-based email security provider offering Secure Email Gateway (SEG) and Integrated Cloud Email Security (ICES) solutions. The company is headquartered in Australia and serves businesses globally. MailGuard's platform is designed to detect and block email-borne threats including malware, ransomware, spyware, phishing, spear phishing, CEO fraud (Business Email Compromise), viruses, and spam. The solution operates entirely in the cloud, requiring no on-premises infrastructure, software installation, or manual updates. The company's threat detection is powered by proprietary heuristic algorithms, machine learning (ML), and generative AI. MailGuard positions its approach around identifying what it calls "zero zero-day" threats — emerging email threats that have not yet been catalogued by traditional antivirus vendors — providing protection in real time as threats are identified. MailGuard integrates with major email platforms including Microsoft 365 and Google Workspace, functioning as an additional security layer on top of existing email infrastructure. The service also includes email continuity and archiving capabilities as part of its cloud offering. The target market is businesses of varying sizes that rely on email communication and require protection against criminal intent threats. The platform is delivered as a SaaS model, with no hardware or software management required on the customer side.
