Open Source DAST, Browser Security and EDR: Security Tools Anyone Can Afford
Dynamic application security testing (DAST), browser security and endpoint detection and response (EDR) represent the cutting edge of security technology. Many organizations make huge investments in these tools, but there are viable open source alternatives. It’s worthwhile to familiarize yourself with these alternatives to see if open source tools can substitute for the popular commercial offerings.
Open Source Security Tools: Pros and Cons
Open source security tools come with several notable advantages. Firstly, they offer a financially viable solution for individuals and organizations operating on a tight budget. Secondly, they provide access to the source code, allowing users to modify and tailor the tool to suit their unique requirements. Lastly, these tools are often community-driven, leading to rapid innovation and the continual introduction of new features.
However, open source security tools have their challenges. The most significant is the need for technical expertise to effectively use and customize these tools. Additionally, support is often community-based, which can potentially lead to delays in receiving critical assistance. Lastly, open source tools may lack the polished user interface and comprehensive documentation available with commercial alternatives.
Despite these challenges, the benefits of open source tools often outweigh the drawbacks, making them a valuable resource for enhancing your cybersecurity framework.
Open Source DAST Tools
Dynamic application security testing, or DAST, is a type of security testing that analyzes a web application in its running state. Unlike static testing methods, which review the application’s source code, DAST tests the application as it interacts with inputs and displays outputs.
This real-time testing approach allows DAST tools to identify vulnerabilities that might not be apparent in the source code. These can include security flaws such as Cross-Site Scripting (XSS), SQL Injection, and other OWASP Top 10 vulnerabilities.
Here are notable open source DAST tools:

BeEF provides an excellent way to test the resilience of your web browsers and to identify and fix vulnerabilities before they can be exploited.
Open Source Endpoint Detection and Response (EDR) Tools
Endpoint Detection and Response (EDR) is a type of security technology designed to monitor and protect endpoints—devices that connect to your network, such as computers, smartphones and tablets. EDR tools continuously monitor these devices, detecting and responding to potential security threats.
One of the key features of EDR tools is their ability to collect and analyze data from endpoints. This data can provide valuable insights into your network’s security status, helping you identify potential vulnerabilities and respond to threats more effectively.
In addition to detection and response capabilities, EDR tools also offer prevention features. They can block known malware and other threats, preventing them from infiltrating your network. Some EDR tools also offer remediation capabilities, helping you recover from a security breach and minimize its impact on your business.
