Website security is of paramount importance in the wake of increasing cybercrimes each day. Organizations need to put their best foot forward when it comes to keeping the hackers at bay.
One of the ways of doing so is by using a Web Application Firewall (WAFs). WAF’s are cloud-managed services/software that constantly monitors incoming and outgoing traffic to prevent web attacks. Web application firewalls are specialized for website and web applications.
