Advanced Protection Features
Syntax-Based Detection
SafeLine employs an advanced non-rule detection algorithm based on syntax analysis, which significantly enhances the accuracy and recall rate of detecting threats. Unlike traditional WAFs that rely on regular expressions, SafeLine uses context-free grammar, commonly found in programming languages, to analyze potential threats.
Example:
Consider the sentence: "The union select members from each department to form a committee."
Traditional WAFs might flag this as a SQL injection attempt due to the presence of the keywords "select" and "from." However, SafeLine evaluates whether the sentence adheres to the formal syntax of the SQL language, reducing false positives.
Rate Limiting
Protect your applications and APIs from abuse by limiting traffic that exceeds predefined thresholds. Rate Limiting helps defend against denial-of-service (DoS) attacks, brute force login attempts, traffic surges, and other forms of abuse targeting your APIs and applications.
- IP-Based Rate Limiting: Use this feature to protect unauthenticated endpoints, limit requests from specific IP addresses, and prevent abuse from repeat offenders.
CAPTCHA Challenge
SafeLine implements CAPTCHA challenges based on threat intelligence and client-side security checks to shield your website from bot attacks. When enabled, SafeLine preemptively verifies the browser environment's legitimacy, allowing human users to access while blocking crawlers and automated programs.
Authentication Challenge
When the authentication challenge is enabled, visitors must enter a username and password to gain access. Users without the correct credentials will be blocked, adding an additional layer of security.
Dynamic Protection
Dynamic Protection encrypts the HTML and JavaScript code on your website each time it is accessed, effectively blocking crawlers and automated exploit programs.
- JavaScript: SafeLine obfuscates JavaScript code dynamically. The left side of the example shows the code before obfuscation, and the right side shows the code after.
- HTML: SafeLine dynamically encrypts HTML code, which is then automatically decrypted by the browser. The left side of the example shows the HTML code before encryption, and the right side shows the code after encryption.
Threat Intelligence Feeds
SafeLine blocks connections from IP addresses associated with known threats, including open SOCKS proxies, VPNs, botnets, command and control servers, malware sources, and anonymizers. This feature helps prevent malicious actors from accessing your network.
