Imperva solutions continuously adapt to evolving threats and enable security professionals, network managers, and application developers to mitigate the risk of a data breach and address compliance requirements

What is a Web Application Firewall (WAF)?

An appliance or cloud service that protects online applications against internal and external attacks.

Why is a WAF Important?

Every day organisations face Web attacks from many sources. Custom attacks such as SQL Injection and Cross Site Scripting easily get around signature-based solutions like IPS and NG Firewalls. Organisations can manually patch vulnerabilities in their web applications but this approach is costly, time consuming and often can only be done in a change window so the threat can remain for a considerable amount of time.

Most traditional security devices including firewalls were designed to protect the network not web applications. Plus it won’t stop attacks like site scraping, DDoS, and fraud. This means attacks such as SQL Injection and Cross Site Scripting easily evade existing security.

To protect critical Web applications, organisations need a Web Application Firewall.
