- Secure Globalization: The web is a global market place, and cross-site scripting is a global issue. An attack can be coded anywhere, and Anti-XSS now protects against XSS attacks coded in dozens of languages.
- Security Runtime Engine: The Security Runtime Engine (SRE) provides a wrapper around your existing web sites, ensuring that common attack vectors to not make it to your application. Protection is provided as standard forCross Site ScriptingSQL Injection.
