What are Government Client-Side Protection Platforms?
Client-side protection platforms are security tools designed to protect users from threats that can arise when interacting with websites. These platforms monitor and secure the client-side environment, such as web browsers, against vulnerabilities like cross-site scripting (XSS), malicious JavaScript, and other client-side attacks. They provide features such as real-time threat detection, script monitoring, and content security policies (CSP) enforcement to ensure that the web content being loaded is safe and hasn't been tampered with. By securing the client side, these platforms help prevent data breaches, session hijacking, and unauthorized access to sensitive information during web interactions. This protection is crucial for maintaining the integrity and security of online user experiences. Compare and read user reviews of the best Government Client-Side Protection platforms currently available using the table below. This list is updated regularly.
