Proxy Service for Safe Browsing
The proxy service is designed to ensure safe browsing by prefiltering site content. It modifies the website to remove potentially harmful elements, such as JavaScript, remote content loading, and macros, thereby providing a safer browsing experience. The proxy service provides a layer of security by prefiltering and manipulating website content. While it ensures safe browsing, it may cause compatibility issues with specific sites. The service is continually improved to strike a balance between security and usability.
Not all websites can be proxied
To prevent access or knowledge of sensitive websites, you cannot proxy any financial, healthcare, email, or other similar sites that may potentially expose users' sensitive data.
How It Works
Request Handling:
- When a user attempts to access a website, the proxy service intercepts the request. Instead of directly serving the site, the proxy service downloads and processes the content.
Content Prefiltering:
- The proxy service removes or alters elements that could pose security risks. This includes filtering out JavaScript, blocking remote content loading, and disabling macros.
Website Manipulation:
- The proxy service modifies the website's links and structure to ensure all interactions remain within the proxy. This prevents the user from directly accessing potentially harmful content.
Rendering Safe Content:
- The processed and safe version of the website is then served to the user. While the site may look similar to the original, it is stripped of any elements that could compromise security.
Limitations
Website Compatibility:
- Some websites may not load properly or break due to the heavy manipulation required for safe browsing. This is a known limitation and is part of the trade-off for enhanced security.
Hardcoded Blocks:
- Certain websites, such as banks and email services, are hardcoded to prevent proxying. This prevents man-in-the-middle attacks and ensures the highest level of security for sensitive information.
Example:
- If a user tries to access
google.com, the proxy service will download the site, filter out unsafe elements, and serve a modified version. Users can browse safely, but interactions are controlled to prevent security risks.
