Guardian Mail
Email security for Microsoft 365, with a human behind it.
Every message into a protected mailbox is checked for spoofing, phishing links and dangerous attachments. Anything the automated checks cannot settle goes to an analyst — and the person who reported it gets a plain answer back, not a score.
No MX change
One admin-consent click connects a tenant. Mail routing is untouched.
Nothing is rewritten
Messages are moved to quarantine, never modified. Signed mail stays valid.
Evidence, not verdicts
Every decision shows the specific signals that produced it.
