MxGuard Personal

MxGuard Personal is a cloud-delivered, hybrid-AI email security gateway for a single personal domain that stops spam, phishing, malware and email compromise before they ever reach your inbox. Point your domain's MX record at MxGuard and every inbound message is scored, sorted and forwarded on to your real mail server — with a single web console to manage everything. £4.59 per month for 1 domain, with 3 mailboxes included.

How it works

MxGuard sits in front of your existing mail server. A gradient-boosted machine-learning classifier scores the easy 95% of mail in milliseconds. The borderline messages — the ones that matter most — are handed to Claude, Anthropic's large language model, which reads them the way a person would before a verdict is reached. Every verdict comes with a plain-English reason, so you can always see exactly why a message was tagged, quarantined or rejected.

Why old filters fail and MxGuard doesn't

Rule-based and Bayesian filters were built for an era of obvious spam. They miss the carefully written, well-targeted attacks: CEO impersonation, invoice redirection, gift-card fraud, lookalike domains and AI-written phishing with perfect grammar. These payload-free attacks sail past legacy filters — and they are exactly where MxGuard's LLM layer is strongest.

What MxGuard stops

• Phishing — credential-harvest pages, fake login flows and OAuth-consent traps.
• BEC and impersonation — CEO fraud, invoice redirection, supplier impersonation, gift-card scams.
• Malware and ransomware — ClamAV scans every attachment, including archives; macro-bearing Office docs and HTML smuggling scored heavily.
• Bulk spam and UCE — classic spam, snowshoe and hailstorm campaigns, with near-zero false positives on legitimate bulk mail.
• Lookalike domains — homoglyph attacks, doubled letters and ccTLD swaps, checked at envelope, From header and reply-to.
• Backscatter and spoofing — SPF/DKIM/DMARC enforcement plus ARC sealing through forwarding.

Included on every domain
