What is Web Application Firewall

Masz pytania?

Web Application Firewall checks web traffic for suspicious activity. When using WAF, you can apply a set of rules to filter out illegitimate traffic automatically. WAF is able to, for example, apply ModSecurity rule sets to deal with OWASP vulnerabilities in order to determine which traffic to block or allow. It can block comment spam, cross-site scripting attacks and SQL injections. Grey Wizard utilizes WAF to safeguard your websites and apps against web attacks which may lead to data loss and outages, both of which will cost you money. You can use custom security rules to enforce appropriate security procedures and eliminate false positives. GreyWizard's Web Application Firewall makes it easy for you and your company to respond to attacks in seconds without slowing down your website.

What Web Application Firewall protects against?

WAF protects your website against application level attacks. They differ from other types of attacks in that they target areas where your application is the most vulnerable and does not require much bandwidth. Cross-site scripting (XSS), SQL injections or zero-day exploits are only some of the threats. Without our protection, the majority of such attacks go unnoticed. What is particularly important, application-level attacks may not only block access to your website, but cause leakage of sensitive data, such as your client database or credit card numbers.
