Cloud-based mail security gateway powered by machine learning. Stops spam, phishing and malware in under 5 milliseconds — with no hardware to deploy and no capital investment. Every message is scored by a custom-trained classifier and, where the verdict is uncertain, escalated to Claude AI for a second opinion. Bad mail is rejected, quarantined or tagged before it reaches your inbox, while legitimate mail flows through untouched.
Email security trusted by businesses across the UK and globally.
From a 33-year-standing company.
Why MxGuard
Traditional anti-spam tools were designed decades ago. MxGuard replaces them with a modern ML-first architecture — cloud-delivered, transparent, and self-improving.
Targeted phishing, BEC, malware attachments, credential harvesters — caught by an ML classifier (AUC 0.988) plus Claude AI second-pass on borderline cases.
