Web application firewalls are used to safeguard web applications against attackers. They operate as intermediaries between web servers and client devices to intercept HTTP conversations and filter out suspicious traffic while also blocking unauthorized data from leaving the web application.
A WAF can be deployed as software, an appliance or as a service and used by individuals, startups and small/medium-sized businesses alike.

Product is offered as physical, virtual and container appliances for deployment in data center or cloud environments. Scalable design caters to large enterprises, service providers and carriers while its unified platform reduces deployment costs and simplifies security management – also enabling users to scale performance and capacity as their needs expand. WAF, XML firewall and web traffic acceleration features help businesses improve application performance; its machine learning detection engine detects abnormal behaviors – differentiating between benign and malicious events without producing false positives which drive administrative overhead costs.
AppTrana
AppTrana is an all-encompassing cloud-native WAF solution, which detects application layer threats such as the OWASP Top 10 and Zero-Day vulnerabilities, accelerates website assets, protects against DDoS/Bot attacks, provides managed rules on an ongoing basis to keep up with new risks/threat vectors, and has multi-step anti-attack techniques to stop even sophisticated Layer 7 DDoS/Bot attacks without impacting performance.
WAFs filter both incoming and outgoing traffic to detect and block malicious activity, including SQL injection and cross-site scripting (XSS) attacks that target specific web applications. They look out for common attack patterns like SQL injection and cross-site scripting as indicators that an attack has targeted them, as well as looking out for other indicators like unauthorized access or suspicious Cookie headers to make this determination.
AppTrana provides automated scanning and on-demand manual penetration testing to quickly find vulnerabilities, while providing a 360deg view of security status, custom rule creation/deployment, and round-the-clock monitoring by security experts.
