Top 3 Cloud Web Application Firewall to Stop Website Attacks (for Small to Medium Business)

97% applications tested by Trust wave had one or more vulnerabilities.

With the rise of web threats, it’s essential for any web application to have a proper firewall in place to protect from attacks for non-disruptive online business operation.


Having vulnerable files, plugin, software or misconfiguration on your server can expose to security risk, which may have the financial and reputational loss.

Multiple online tools can help you to find the security vulnerabilities and malware for FREE. However, when it comes to fixing or protecting them, then you got to spend a little bit.
