3. The "Dynamic Protection" Feature

What is "Dynamic Protection"? According to SafeLine’s official description, Dynamic Protection adds dynamic characteristics to web pages without altering the visible content. This means that even static pages exhibit dynamic randomness.

As a reverse proxy, SafeLine dynamically encrypts and protects web page code. The Dynamic Protection feature offers several key benefits:

  • Protects the privacy of front-end code
  • Prevents web scraping
  • Blocks vulnerability scans
  • Mitigates the exploitation of attacks

Enabling the Dynamic Protection feature significantly enhances your website's security. This feature not only analyzes and intercepts malicious traffic in real-time but also dynamically encrypts HTML and JavaScript code, making each visit to your site unique and random. This dynamic encryption technology effectively complicates automated exploitation programs, making it challenging for web crawlers and automated attack tools to recognize and parse the website content. Therefore, enabling Dynamic Protection is a crucial step in protecting your website against crawlers and automated attacks.

4. Experience the "Dynamic Protection" Feature

To experience Dynamic Protection, go to the configuration site and click on the protection settings to enable the feature.

Here’s a comparison: on the right side is the code before encryption, and on the left side is the code after encryption. It's evident that the JavaScript code has been dynamically encrypted, showcasing the powerful capability of the "Dynamic Protection" feature. For companies that prioritize preventing web crawlers from accessing their data, Dynamic Protection proves to be exceptionally effective and unique!
