Web Application Firewall

Manage web app security and shield it from vulnerabilities

The risks and vulnerabilities that can expose company data leading to financial loss are growing along with using web apps. Monitor the security infrastructure of the web app with our web application firewall and maintain peak performance without worrying about any cyber threat.

What is a Web Application Firewall (WAF)?

A web application firewall (WAF) monitors, filters and blocks data packets as they travel to and from a website or web application. A WAF can be either network-based, host-based or cloud-based and is often deployed through a reverse proxy and placed in front of one or more websites or applications. Running as a network appliance, server plugin or cloud service, the WAF inspects each packet and uses a rule base to analyze layer seven web application logic and filter out potentially harmful traffic that can facilitate web exploits. WAFs are handy to companies that provide products or services over the internet, such as e-commerce shopping, online banking and other interactions between customers or business partners. ​

How Does A Web Application Firewall Work?

A WAF analyses Hypertext Transfer Protocol (HTTP) requests and differentiates between malicious and non-malicious parts of the conversation and data. The main parts of HTTP conversations that WAF analyses are GET and POST requests. GET requests are used to retrieve data from the server, and POST requests are used to send data to a server to change its state.

Benefits of a Web Application Firewall?

A web app firewall protects your digital data with multi-layer security. Prevent attacks like cross-site scripting (XSS), cookie poisoning, SQL injection, etc. and safeguard your valuable data from breaches and attacks.

Web Application Firewall Deployment Options

Network-based WAF

A low-latency hardware solution installed locally on the network. While effective, this option requires significant storage and typically carries high maintenance costs, making it one of the more costly deployment options.

Host-based WAF

A customizable solution that is integrated into the application software. While less expensive than a Network-based WAF, this option is often more complex to deploy and still consumes considerable resources.

Cloud-based WAFs

The most affordable deployment option, Cloud-based WAFs are turnkey solutions offered by the cloud provider, such as Amazon Web Services (AWS). In this model, implementation and updating is the responsibility of the cloud provider.
