Security

Two security platforms, built in.

Most hosts bolt spam filtering on as a paid extra and do nothing about signup fraud. TDesk runs our own AI security stack in front of every account — included free at every tier.

MXGuard AI antispam gateway

An AI mail-security gateway in front of every domain's inbound mail. A gradient-boosted classifier (LightGBM, 0.988 AUC) scores each message inside a full reputation pipeline — not a single blocklist — so legitimate mail gets through and spam, phishing and malware don't.

✓ LightGBM ML classifier, 0.988 AUC
✓ Postscreen DNSBLs: Spamhaus ZEN, CBL, SORBS, Mailspike, PSBL
✓ URIBL on every link: uribl, surbl, Spamhaus DBL
✓ SPF, DKIM, DMARC and ARC sealing
✓ ClamAV virus scanning + attachment-risk scoring
✓ Quarantine, daily digests, per-domain sender rules
✓ Recipient verification — no backscatter
✓ Included free on every plan

Veritus Signup-fraud screening

Signup-fraud screening that scores every new registration before an account goes live. Catches throwaway emails, high-risk geographies, disposable numbers and known-bad signals — keeping the platform clean for legitimate customers, and protecting any customers you host.

✓ Real-time risk score on every signup
✓ Email, phone, country and IP signals
✓ High-risk registrations held for review
✓ Protects any customers you host
✓ Runs automatically — nothing to configure
✓ Included free on every plan
