With Proofpoint’s threat intelligence and detection, you’ll have a stalwart defense
against sophisticated threats while minimizing false positives.

We use reputation, URL rewriting, and predictive and click-time sandboxing to
detect payload threats, such as those that come through attachments and URLs. Detecting through evasion and obfuscation like CAPTCHA, password protection, render-heavy sites, redirectors and file-sharing sites is built-in.
