A web application firewall (WAF) prevents website hacks and data breaches. Visitors trust you to keep them secure. Ecommerce sites that take credit card payments must be compliant with the PCI data security standards–even if it uses a third-party payment processor. Regardless of the size or type of website, a WAF will protect the integrity of your content, your website traffic, and your brand reputation.
By intercepting and inspecting traffic, a website firewall blocks hackers and malicious traffic. Without a cloud-based WAF and CDN, websites can be taken down with DDoS attacks or can be infected by exploited code vulnerabilities and poorly secured user accounts.
We encourage you to research your options and use this guide to choose the best WAF for you.
A WAF is a cloud-based or hardware protection system that includes intrusion prevention and content delivery networks to ensure the integrity, confidentiality, and availability of websites. Activating a WAF protects visitors and business from data breaches, attacks, and malware infections. Hackers will abuse compromised websites by injecting SEO spam, drive-by-downloads, defacements, and malicious redirects. Keep visitors and web content secure by preventing vulnerability exploitation, brute-force (password guessing), and DDoS attacks. In our 2018 Hacked Website Report, we identify some of the most common types of malware and the blacklist authorities that block visitors from visiting compromised websites.
All firewalls monitor and block traffic. A WAF protects web applications (websites) from external malicious requests to the web server, while network firewalls protect data flowing between web servers. Computer firewalls are software firewalls supplied by the operating system or by anti-virus companies.
Every WAF has different features and pricing. Some charge for additional features like Layer 7 DDoS protection, while others charge fees for customization. Here are the features to look for in a WAF.
By detecting and blocking known hacking methods and behaviors, a website firewall keeps your site protected against brute force attacks, data breaches, and attempts to inject content into your web server.
Hackers quickly exploit vulnerabilities, and new ones are always emerging (called zero-days). A good website firewall will patch the holes in your website even if you haven’t applied security updates.
A website firewall should stop anyone from accessing your protected pages if they aren’t supposed to be there, and make sure attackers can’t use brute force automation to guess your passwords.
Distributed Denial of Service (DDoS) attacks attempt to overload your server or application resources. By detecting and blocking all types of DDoS attacks, a website firewall makes sure your site is available if you are being attacked with a high volume of malicious traffic.
Most WAFs include a content delivery network (CDN) to cache your website for faster global access. This speeds up your website and keeps visitors happy while reducing the load on your web server.
