Why Email Remains the #1 Attack Vector

Despite being decades old, email remains the single most exploited communication channel by threat actors. Sophisticated spear-phishing, CEO fraud (BEC), and malware-laden attachments bypass native platform filters daily. Twiis applies multi-layered AI analysis — combining sandboxing, link rewriting, sender verification, and behavioral anomaly detection — to stop threats that Microsoft Defender and Google's built-in filters miss.

Key Capabilities

AI Anti-Phishing

Machine learning models trained on billions of threat signals to detect zero-day phishing attempts, including highly targeted spear-phishing and whaling attacks.

Business Email Compromise (BEC) Detection

Identity graph analysis and communication pattern modeling to detect impersonation of executives, vendors, or finance teams before wire transfers or data theft occur.

Attachment Sandboxing

Every attachment detonated in an isolated cloud sandbox before delivery — detecting malware, ransomware droppers, and exploit documents that static AV misses.

URL Rewriting & Time-of-Click Analysis

All links are rewritten and re-evaluated at click time — blocking URLs that turn malicious after the email lands in the inbox.

DMARC / DKIM / SPF Enforcement

Full authentication stack configuration and monitoring to prevent domain spoofing and protect your brand's email reputation globally.

Incident Response & Remediation

One-click mass email retraction across all mailboxes when a threat is identified post-delivery, with automated incident reporting and user notifications.

Platforms We Protect
