URL rewriting is a cornerstone of Urldefense.com’s operation, enabling the platform to intercept and analyze web links before users access them. This process involves modifying URLs to redirect traffic through Proofpoint’s security infrastructure, where each link is scrutinized for potential threats.

The process unfolds in distinct stages, each contributing to the overall security posture.

URL Wrapping: Encapsulation for Security

The initial step involves wrapping the original URL. This means that the original URL is encapsulated within a new, Proofpoint-generated URL.

Think of it as placing the original URL inside a protective envelope.

This wrapper URL serves as a pointer, redirecting the user’s request to Proofpoint’s servers for inspection before forwarding them to the intended destination, if deemed safe.

Redirection Process: A Secure Detour

When a user clicks on a wrapped URL, the request is first routed to Urldefense.com’s servers. Here, the URL undergoes a series of checks to determine its safety.

This is the redirection process. These checks can include real-time analysis against threat intelligence feeds, reputation databases, and behavioral analysis.

If the URL is deemed safe, the user is seamlessly redirected to the original, intended website. If, however, the analysis reveals malicious content, the user is blocked from accessing the site, and an alert is triggered.

The Advantages of URL Rewriting

URL rewriting offers a trifecta of benefits: analysis, click tracking, and malicious site blocking. By intercepting and analyzing URLs in real-time, Urldefense.com can identify and block access to malicious websites before they can compromise users or systems.
