Deploying AcuSensor in Acunetix 360 On-Premises

Acunetix AcuSensor increases the accuracy of an Acunetix scan by improving the crawling, detection, and reporting of vulnerabilities while decreasing false positives. Acunetix AcuSensor can be used on .NET (including .NET Core), JAVA, and PHP web applications.

Deploying AcuSensor

The unique Acunetix AcuSensor Technology identifies more vulnerabilities than a black-box web application scanner does and also further minimizes false positives. In addition, it indicates exactly where vulnerabilities are detected in your code and reports debug information.

Acunetix AcuSensor requires a sensor to be deployed on your server. This sensor is generated uniquely for each website for security reasons.

Deploying AcuSensor is optional. Acunetix is still best in class as a black-box scanner, but AcuSensor improves accuracy and vulnerability results when scanning your web applications.
