7 Best Cloud Web Application Firewall (WAF)

Looking for the most effective web application firewall to secure your online business?

A web app firewall or WAF is your instant, virtual protection against Layer 7 attacks. While a vulnerability scanning tool finds security issues in your website, you still need to fix them.

According to the Web Application Security Statistics Report, companies take 146 days on an average to fix even the critical vulnerabilities. Imagine, your business being open to attacks for about five months.

Until you fix the issues in code, a cloud-based web application firewall or WAF is the best protection. It blocks all illegitimate traffic that tries to exploit the vulnerability.
