Does your website have a bouncer, and if not, why not? Think about it. Websites are being probed by hackers millions of times every day, using sophisticated and automated hacking tools looking for any vulnerabilities they can exploit. It’s like having a store on Main Street that’s swarmed with visitors every single day, only you can’t tell which customers are going to pay you and which ones are going to shoplift.
A web application firewall, or WAF, is like a bouncer for your website. It stands between you and the street and determines based on a variety of criteria who gets in and who’s kicked out. It acts as a filter to make sure the visitors to your online store don’t mean you any harm.
