Agentic email security that doesn't miss

A 90-day lookback of real threats already delivered to your users' inboxes, an efficacy comparison against your current email security, investigation of zero-hour and zero-day threats, and a business impact summary for board and executive reporting. Deploys in five minutes via API. Backed by real production data, not simulated attacks.

Interceptor is Varonis's AI-native phishing defense. It combines email security, browser security, and email data protection in one platform, using multi-modal detection (NLP, computer vision, and behavior analysis) and a zero-trust phishing sandbox to catch attacks that other tools miss.

When a new message arrives, Interceptor ingests it. Four engines run in parallel: the relationship graph checks sender behavior against org context, Interceptor's LLM and ML models score language and intent, the phishing sandbox detonates every URL, and threat intelligence enriches the signals. Malicious messages are removed. Safe messages are delivered without delay.

Traditional SEGs rely on blocklists, signatures, and predefined rules. Interceptor learns from user and organizational behavior, correlates multi-modal signals, and validates every link and attachment through direct inspection. This catches novel and highly targeted attacks that legacy defenses cannot, with fewer false positives and less operational overhead.

Interceptor proactively scans nearly every newly registered domain and published URL in its phishing sandbox. Because Interceptor is often the first AI to see and analyze the site before any other agent or human, it blocks malicious domains and URLs 12 to 24 hours before other solutions on the market.

Interceptor builds behavioral and linguistic profiles for every sender based on writing style, tone, and typical recipients. When a message deviates from established norms (unusual requests, unexpected contacts, unfamiliar tone), Interceptor flags it. This catches impersonation attempts that would look legitimate based on content alone.

Interceptor detects over 30 threat types across five families. Business email compromise includes invoice fraud, payroll theft, and gift card scams. Social engineering includes job scams, sextortion, and lottery scams. Phishing links and attachments span credential stealing, QR phishing, tech support scams, and rogue software. The full taxonomy lives in the Varonis Threat Cyclopedia.

Interceptor scans every mailbox, shared mailbox, and calendar. It classifies sensitive data in messages and attachments, flags risky configurations and delegations, and alerts on abnormal send, receive, and forwarding activity. When an account is compromised, you see the blast radius across the Varonis Data Security Platform.

Five-minute installation via API. No mail flow changes, no MX record swaps. The browser extension pushes through your existing MDM or endpoint management.
