Top 5 Tools to Maximize Security for your Open Source Application

As organizations want to speed up and catch up with their competitors and customers, many engineering teams no longer write proprietary software. Instead, they assemble software from various 3rd party components, including open-source components.

As developers utilize hundreds to thousands of various open-source components, all with individual licenses, this comes with a risk. It’s impossible to audit everything because of the speed. Therefore, we need tools to help scan for vulnerabilities, license compliance, etc. Thankfully, today we have various tools to choose from to support our engineering team and legal team while protecting the company from risk.


Here are some things to check before buying to secure your organizations’ open source components and application.

  • Package Analysis: check whether a package comes from NuGet, Maven.
  • Security Analysis: checks for dependencies, vulnerabilities, exploit maturity, and accuracy of false positives.
  • License Compliance: manages the different licenses across software projects. Moreover, it is essential because we don’t know if a developer copies and pasted a code from somewhere in the internet space without knowing the license behind those codes.
  • Inventory of Vulnerabilities: this helps the engineering them see the vulnerabilities and provides the action items to automate them.
  • Multiple language support: most engineering teams aren’t focused on one technology stack because newer versions of programming languages are created or released. So it is vital to have multiple programming language support.
  • Easy Integration: this could be in the IDE, pull requests, and repositories.

Now that we have at least a basic understanding of this analysis, in this article, we’ll explore the top 5 tools to maximize the security of your open-source application.


Fossa focuses on improving organizations’ development workflow to track, manage, and mitigate issues with the software project’s open-source components. Moreover, they provide source code management that includes source code review.

Here are the two main things Fossa guarantees:

  • Compatible and a flexible tool for today’s modern software engineering practices.
  • Provides a useful feedback loop that empowers the legal team to focus more on strategic issues. Thus, it helps the legal team and engineers to collaborate more often.

WhiteSource Bolt

WhiteSource Bolt is a free tool designed for developers, and it is intended to find and fix open source vulnerabilities, just like the previous tools we have discussed. It runs on GitHub, and it is an extension of Azure DevOps and works by scanning all of your repositories by validating and checking vulnerabilities.

Moreover, every time a particular repository is scanned and examined thoroughly, this tool will do its best to generate a complete inventory and license reports of all open source components used within your repository.

Here are the features of White Source Bolt:

  • Continuous Integration
  • License Compliance
  • Vulnerability Identification
  • Alerts
  • Reports
  • Automated Feedback
  • Suggested Fix

OWASP Dependency Track

Fundamentally, it is a Supply Chain Component Analysis Platform, which gives the organization the capability to identify and reduce risk from 3rd party and open source components. The unique thing about this tool is it uses an approach by leveraging the Software Bill of Materials (SBOM).
