**3. "Dynamic Protection" Feature**
What is "Dynamic Protection"? According to the official description, Dynamic Protection is a feature that adds dynamic characteristics to web pages without altering the content the user sees. This means that even static pages will exhibit dynamic randomness.
As a reverse proxy, Safeline dynamically encrypts and protects web page code. The Dynamic Protection feature offers several benefits, including:
● Protecting the privacy of front-end code
● Preventing web scraping
● Blocking vulnerability scans
● Mitigating exploitation of attacks...
 
As shown in the image, this is the HTML code before Dynamic Protection is enabled.

After enabling the "Dynamic Protection" feature, the HTML code transforms as follows:

JavaScript encryption works similarly. Here is the JavaScript code before encryption:

After enabling "Dynamic Protection," the JavaScript code appears as follows:

After enabling the Dynamic Protection feature, the security of your website will be significantly enhanced. This feature not only analyzes and intercepts malicious traffic in real-time but also dynamically encrypts HTML and JavaScript code. As a result, each visit to your site will present these codes in a unique and random manner. This dynamic encryption technology effectively increases the difficulty for attackers using 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 safeguarding your website against crawlers and automated attacks.

**4. Experience the "Dynamic Protection" Feature**
First, in the configuration site, click on the protection settings to enable the feature.

Then, you can visit our protected site. Upon visiting, you'll notice that our site is dynamically encrypted right from the start. You'll need to perform a decryption process to access the website. This significantly reduces the effectiveness of web crawlers and ensures high security.

**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. This showcases 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!
