Applications accessible via the Internet can be the backdoor for access to data. It requires not only strong accreditation of users but also the shielding of the application itself.
Most organizations today use web applications to communicate with customers, partners and employees. Also, the trend is to move to the web and applications that traditionally belonged to the business core of the enterprise, so that there is direct access from everywhere, increasing the availability and the ease of updating.
For attackers, these web applications are increasingly popular targets, as most of them contain exploitable vulnerabilities. A Web Application Firewall (WAF) helps protect valuable applications and the data they contain by constantly monitoring data traffic and imposing policies to detect and rule out threats.
