Contrast Assess vs w3af

Contrast Assess is an Interactive Application Security Testing tool that analyzes application code while the software runs. An agent instruments the application with sensors and examines libraries, frameworks, custom code, configuration, runtime control and data flow, HTTP traffic, and back-end connections. Its approach combines static, dynamic, and interactive testing. Assess can identify vulnerabilities in custom code, open-source libraries, frameworks, and application configurations, including SQL injection, cross-site scripting, and insecure configurations. It continuously monitors applications and APIs, and presents vulnerability lists with remediation guidance, application scores, route coverage, flow maps, and compliance and policy reports. It is designed for developers and AppSec teams to use in IDE, test, and QA environments. Integration with Contrast SCA can identify vulnerable third-party libraries and determine whether their vulnerable methods are called by the running application. Supported languages include Java, Kotlin, Scala, .NET Framework, .NET Core, C#, VB.NET, Node.js, Python, Go, and PHP. Contrast states that source code and binaries stay on customer servers. Assess supports API, Linux, macOS, self-hosted, web, and Windows environments; pricing is on request, and hosted and on-premises customers require application licenses.

w3af is a free, open-source web application security scanner for vulnerability assessments and penetration tests. It can identify more than 200 vulnerabilities, including cross-site scripting, SQL injection, and OS command injection. Its workflow starts with crawler plugins that find URLs and injection points, continues with audit plugins that check for vulnerabilities, and can use attack plugins to exploit findings. Other plugin types cover infrastructure detection, request and response analysis, output, brute force, request modification, and evasion.

Users can scan and analyze results in a GTK graphical interface or a console. Web application payloads can interact with Metasploit when an exploit provides exec() capability. Developers can use the REST API from development languages and run it in Docker; scripts and the API also support automation. The project documents Linux and macOS installation, including running in Docker without installing w3af dependencies. It is available for Linux, macOS, web, API, and self-hosted deployment. REST API traffic over HTTP is unencrypted, so the documentation recommends added protection such as an SSL proxy for publicly reachable deployments.
