Managing software dependencies isn’t just about coding – it’s about avoiding legal and financial risks tied to licensing. Dependency license compliance ensures you’re following the rules for using, modifying, and sharing third-party software, especially open-source components. Here’s why it matters:

• Legal Risks: Non-compliance can lead to lawsuits, hefty fines (average cost: $14.82M), and forced source code disclosure.
• Operational Impact: Delays in product launches and damaged business relationships are common consequences.
• Complexity: Transitive dependencies (dependencies of your dependencies) make manual tracking almost impossible.

Key Steps for Compliance:

1. Understand Licenses: Know the terms of Public Domain, Permissive, Copyleft, and Proprietary licenses.
2. Use Automation: Tools like Software Composition Analysis (SCA) and SBOMs (Software Bill of Materials) simplify tracking and compliance.
3. Monitor Continuously: Regular scans and updates help catch issues early.
4. Meet License Obligations: Ensure proper attribution, source code sharing, and adherence to license terms.
5. Handle Violations Quickly: Address breaches by removing, replacing, or licensing components properly.

Why act now? With 97% of codebases containing open-source components and 56% having license conflicts, compliance is a must for avoiding legal troubles and keeping your software secure.

Software Licenses and Risks

Understanding the types of software licenses and their compatibility is crucial for managing dependencies and ensuring compliance. With over 90% of companies incorporating open-source software into their proprietary products, knowing the obligations tied to each license type can save organizations from costly violations. Let’s dive into the major software license types and the risks they may pose.

Common Software License Types

Software licenses define how software can be used, modified, and shared. They protect developers’ intellectual property, but each license type comes with its own set of rules and restrictions.

Public Domain licenses are the most permissive. For example, GIMP, the open-source graphics editor, allows users to create and distribute images for personal or commercial use without any requirements for compensation. These licenses impose no restrictions on modification, use, or redistribution.

Permissive licenses, like MIT and Apache 2.0, offer flexibility while retaining some intellectual property protections. These licenses allow you to modify, use, and distribute software, provided you retain copyright notices. They’re also compatible with proprietary software, meaning you can use them without releasing your source code.

Copyleft licenses, such as the GNU General Public License (GPL), take a different approach. They use copyright law to ensure software remains free for everyone. For instance, Audacity, the popular audio editing software, operates under the GPL, which allows users to modify and distribute the source code but requires derivative works to be licensed under the same terms.

Copyleft licenses come in two forms: strong copyleft and weak copyleft. Strong copyleft licenses, like the GPL, don’t allow integration with proprietary software. In contrast, weak copyleft licenses, such as the GNU Lesser General Public License (LGPL), allow for dynamic linking with proprietary software but still require source code disclosure for changes made to the library. The compression tool 7-Zip is an example of software using LGPL.

Proprietary licenses are the most restrictive. They typically limit modification, redistribution, and reverse engineering. Microsoft Windows, for instance, prohibits users from sharing the software or publishing performance benchmarks.

License Type	Permissions	Restrictions
Public Domain	Modify, use, distribute, commercialize	None
Permissive (e.g., Apache 2.0, MIT)	Modify, use, distribute	Retain copyright information
Copyleft (e.g., GPL)	Modify, use, distribute	Derivative works must use the same license
Proprietary	Use as defined in EULA	No modification, redistribution, or reverse engineering

License Compatibility Issues

Compatibility becomes a pressing issue when combining components with different licenses. With 60% to 80% of software relying on open-source components and 53% of codebases containing license conflicts, understanding compatibility is vital to avoid legal trouble.

Problems arise when licenses impose conflicting requirements. Richard Stallman explains:

"If license A says extended programs must be under license A, and license B says extended programs must be under license B, they have an irreconcilable disagreement; the license of the combined program would have to be A, and it would have to be B".

Permissive licenses like MIT and Apache 2.0 are generally easy to combine with other licenses, including some copyleft licenses. However, copyleft licenses often create more complex scenarios. For example, GPL licenses are usually incompatible with each other unless explicitly stated otherwise, requiring derivative works to adopt the same license.

The situation becomes even trickier with transitive dependencies – the dependencies of your dependencies. These hidden layers can introduce unexpected incompatibilities, making compliance a challenge.

Some open-source licenses also include hidden obligations, such as requiring source code disclosure, attribution, or specific notices in distributions. These requirements can create compliance hurdles, particularly when buried deep in dependency chains.

License	Type	Can Be Used in Proprietary Software	Requires Source Code Disclosure
MIT	Permissive	Yes	No
Apache 2.0	Permissive	Yes	No
BSD (2-Clause/3-Clause)	Permissive	Yes	No
GPL (v2/v3)	Strong Copyleft	No (if linked)	Yes
LGPL	Weak Copyleft	Yes (if dynamically linked)	Yes (for library modifications)
AGPL	Strong Copyleft	No	Yes

Regulatory Requirements

Compliance with regulations adds another layer of complexity to license management. Organizations subject to frameworks like GDPR, HIPAA, FISMA, and PCI DSS must ensure their licensing practices align with these regulatory demands. This intersection of compliance and license management can be challenging for many organizations.

Currently, 76% of companies admit to over-licensing out of fear of audits, while 67% lack adequate processes to manage licenses effectively. This reactive approach not only raises costs but also increases risks. Deepa Desai highlights the stakes:

"Software compliance has become a critical concern for today’s digital landscape businesses. With the increasing reliance on technology and the handling of sensitive data, organizations must ensure that their software systems adhere to various legal, regulatory, and industry standards. Failing to comply with these requirements can lead to severe consequences, including legal penalties, financial losses, and reputational damage".

Non-compliance can result in steep penalties, but the financial impact doesn’t stop there. Licensing costs can account for up to 24% of an organization’s IT budget, and 53% of companies exceed their cloud budgets by 20%, with software licenses being a major factor.

To navigate these challenges, organizations need a structured approach. This includes assessing risks, developing policies, implementing technical controls, providing training, monitoring compliance, and continuously improving processes. By proactively addressing compliance, businesses can avoid the financial and legal consequences of poor license management.

Setting Up a License Compliance Program

Tackling license compliance challenges requires a well-structured program. With 96% of applications relying on open-source components, it’s clear that managing licenses effectively is no longer optional – it’s a necessity. A systematic approach ensures your organization avoids risks while staying on top of dependency management.

Creating Policies and Procedures

Start by establishing clear policies that define how your team handles dependencies throughout the software lifecycle.

Understanding license terms is a must. Regularly review license agreements to stay updated on any changes that could affect your use of software.

Setting up implementation protocols ensures consistency. Create detailed procedures for selecting, purchasing, installing, and tracking software. Make sure everyone involved knows the process. For example, define who approves new dependencies, what documentation is needed, and how license details are recorded.

Your policies should also cover these six key steps for managing dependencies: identifying software and dependencies, determining licenses, understanding how they’re used, addressing conflicts, sharing license information, and providing source code when required. Clear, actionable procedures for each step will help your team stay compliant.

Employee training is crucial to turn policies into action. Developers and stakeholders need to understand compliance protocols, license types, potential compatibility issues, and the risks of non-compliance. This education bridges the gap between policy and practice.

Once your policies are in place, maintain an accurate inventory of software components using a Software Bill of Materials (SBOM).

Building a Software Bill of Materials (SBOM)

An SBOM acts as a detailed inventory of all the software components and dependencies in your projects. It provides visibility into your software supply chain and helps identify vulnerable or outdated components.

Tracking every component is essential, including transitive dependencies (those indirectly included). Your SBOM should document component names, versions, license details, source locations, and any known vulnerabilities.

Regular updates are critical as your software evolves. With 85% of software projects containing at least one outdated open-source component, keeping your SBOM current ensures you can address issues promptly. This includes monitoring third-party components for changes in license terms or security status.

Integrating version control keeps your SBOM accurate. As dependencies are added, updated, or removed, your SBOM should automatically reflect these changes to avoid outdated information.

Evaluating vendors and suppliers is another important step. Assess the security practices of third-party vendors involved in your software supply chain. This includes their compliance measures, security protocols, and plans for business continuity.

An SBOM not only provides transparency but also lays the groundwork for automating compliance checks within your development workflows.

Automated Compliance Checks

As software becomes more complex, manual compliance checks are no longer practical. Automation is key, with tools like Software Composition Analysis (SCA) reducing vulnerability remediation time by up to 80%.

Integrating compliance into development workflows is a game-changer. SCA tools can scan code during commits, builds, and pull requests, catching compliance issues early before they escalate into bigger problems.

Real-time monitoring adds another layer of protection. Unlike periodic scans, continuous monitoring detects vulnerabilities and changes in license terms as they happen, enabling faster responses.

Policy enforcement through automation simplifies compliance. Configure tools to automatically flag licenses that don’t meet your policies or exceed vulnerability thresholds. This minimizes manual effort while ensuring adherence to your compliance standards.

Streamlined remediation workflows help developers address issues quickly without delaying releases. Modern SCA tools not only identify problems but also suggest fixes – and in some cases, automate them – making compliance less of a bottleneck.

Automation Benefit	Impact	Implementation Focus
Faster Remediation	Up to 80% quicker fixes	Integrate SCA tools into workflows
Continuous Monitoring	Real-time visibility	Enable automated scans in CI/CD pipelines
Policy Enforcement	Automatic flagging of issues	Configure license and vulnerability rules
Developer Integration	Seamless workflow compatibility	Embed compliance insights into tools

Reachability analysis helps your team focus on vulnerabilities that pose real risks, rather than theoretical ones. This ensures your efforts are targeted where they matter most.

For automation to succeed, compliance checks must fit naturally into your developers’ workflows. Tools should provide actionable insights directly within the development environment, making compliance a seamless part of the process. Ultimately, automated compliance checks should enhance productivity while supporting broader security and compliance goals.

Secure Dependency Management

Managing dependencies securely means taking a proactive stance to address potential risks before they become major issues. With 83% of applications scanned for the first time revealing one or more security vulnerabilities, it’s clear that systematic processes are essential to avoid compliance troubles.

Reviewing Dependencies Before Use

To sidestep compliance headaches, it’s crucial to evaluate dependencies before integrating them into your project. This upfront effort can save time, money, and resources compared to fixing problems later.

• Check maintainer responsiveness. Assess whether the vendor or maintainer is active in fixing bugs, accepting pull requests, and providing support. An unresponsive maintainer can leave you vulnerable to unresolved security flaws and compliance gaps.
• Account for both direct and indirect dependencies. Direct dependencies are the packages you explicitly include, while indirect dependencies are those that your direct dependencies rely on. Both need thorough review to ensure compliance across the entire dependency tree.
• Review commercial contracts for proprietary components. Understand the terms of vendor agreements, including usage rights, support promises, and restrictions, to avoid compliance surprises.

By evaluating dependencies early, you can prevent future complications, reduce the need for costly fixes, and minimize compliance risks. This foundational review supports ongoing monitoring, which we’ll explore next.

Ongoing Monitoring and Audits

Initial evaluations are just the beginning. Continuous monitoring ensures compliance as dependencies evolve. With 22,254 CVEs reported by mid-2024 – a 30% increase from 2023, staying vigilant is more important than ever.

• Automate daily scans. Automated tools can identify compliance gaps and emerging vulnerabilities quickly, allowing you to address problems before they escalate.
• Collaborate across teams. Security, development, and compliance teams should work together to align technical and regulatory goals. Regular policy reviews help adapt to new standards and improve internal processes.

A compelling example comes from a SaaS company collaborating with Diatom Labs. Preparing for VC funding, they used Dependency Track and custom GitHub Actions to meet SOC 2 Compliance. Within a month, they reduced high-severity vulnerabilities by 85%, boosted investor confidence with detailed license reports, and streamlined monitoring with a live dashboard.

Vendor management is another critical piece. Regularly review contracts to ensure third-party security and privacy commitments are up-to-date, protecting your organization from evolving risks.

Meeting License Requirements

Once you’ve established an SBOM and automated monitoring, meeting license requirements becomes the next step in a strong compliance program. Consistent processes are key to addressing obligations like attribution and source code sharing.

• Ensure proper attribution. Include copyright notices, full license texts, and acknowledgments in your documentation or application. A centralized system for tracking these requirements simplifies management.
• Plan for source code obligations. Some licenses require you to make source code available when distributing software. Set up systems to host source code and binaries on your own servers, and consider building binaries yourself when the source is accessible.
• Track changes to licenses. Document modifications to third-party components and confirm they align with the original license terms. Update your source repository and rebuild components as needed.
• Contribute back to projects. Submitting pull requests or patches to original projects can reduce maintenance work long-term, enabling you to adopt updated versions more easily.
• Use version controls. Lock in specific, tested versions of libraries to prevent unexpected updates that could disrupt compatibility.

As software license compliance expert Abhik Chowdhury explains:

"Software license compliance is crucial to ensure that the use of licensed software tools doesn’t go beyond the scope of license agreements".

Ignoring these steps can lead to costly consequences. Inefficient software license management can drain up to 30% of an organization’s IT budget. Regularly reviewing contracts is essential, as vendors may update terms over time. These reviews help you stay compliant and avoid unexpected expenses that could affect your operations and bottom line.

Tools and Automation for Compliance

Keeping track of dependency license compliance manually is nearly impossible with the complexity of today’s software. Modern applications typically rely on open source software for at least 80% of their components. With so many dependencies and fast-paced development cycles, automated solutions are essential to maintain accuracy and keep up with the workload. Let’s look at how tools and automation simplify compliance and integrate seamlessly into modern workflows.

License Detection and Management Tools

Software license management (SLM) tools are the backbone of effective compliance strategies. They offer centralized insights into software usage, license types, and compliance status. These tools go beyond basic tracking, delivering features like real-time monitoring, automated renewals, and detailed reporting.

The most efficient tools share several important features. They include license inventory systems that catalog all software components and their licenses, as well as real-time tracking to monitor usage and compliance continuously. Features like automated renewal reminders help avoid missed deadlines, and integration with identity and access management tools ensures licenses are allocated correctly across teams.

Frameworks such as SPDX and CycloneDX also play a key role. SPDX focuses on license compliance but has expanded to include security metadata, while CycloneDX prioritizes security monitoring.

Practical examples highlight the impact of these tools. For instance, Stitchflow helped a global engineering team address over 200 offboarding gaps in just one quarter. They cleaned up 93% of 812 orphaned accounts before a major SaaS renewal, reclaimed over $60,000 in unused licenses within two weeks, and cut quarterly access reviews from three weeks to less than 24 hours.

An IT Manager at Starburst summed it up well:

"We reviewed 7,000 accounts across multiple applications in just 15 minutes with all the context needed for quick decisions. Renewals no longer keep us up at night."

Benefits of Automated Compliance

Automation transforms license compliance into a proactive and precise process that keeps up with rapid development. Manual methods simply can’t handle the demands of modern, cloud-native applications, where dependencies change frequently and compliance requirements constantly evolve.

One of the biggest advantages is accuracy. Automated tools provide real-time insights and flag potential compliance issues far more effectively than manual processes, which are often slow and prone to errors. This precision is critical, as compliance violations can lead to significant costs and legal risks.

Automation also prevents problems before they happen. Policy-based systems block non-compliant components from being integrated into your software, saving time and money compared to fixing issues uncovered during audits or legal reviews.

Here’s an example of automation in action: one organization used a GitHub Action to scan 1,500 repositories, uncovering 53,000 dependencies and identifying several problematic licenses that needed to be addressed. Without automation, such a task would have been nearly impossible.

As compliance expert Matt Jacobs points out:

"As with all license compliance challenges, identifying open source components and the corresponding license is made much easier by deploying automated scanning and compliance tools."

Handling Violations and Improving Compliance

When it comes to managing dependencies securely, automated compliance checks are just the beginning. Addressing license violations effectively is a crucial part of your strategy. Even with the best tools in place, violations can happen. Tackling them promptly not only minimizes legal and financial risks but also strengthens your compliance framework over time.

Fixing License Violations

Dealing with license violations quickly is essential to reduce exposure to legal and financial repercussions. Start by conducting a thorough audit to pinpoint the affected components, understand the breached license terms, and prioritize addressing direct dependencies over transitive ones, as the former typically carry higher risks. Automated tools can help you assess and rank compliance risks, allowing you to focus on the most critical violations first.

Common approaches to resolving violations include:

• Removing non-compliant components
• Replacing them with alternatives that have compatible licenses
• Securing the proper licensing for continued use

"Implement processes to address and rectify license violations quickly. Steps may include removing or replacing non-compliant components, releasing updated software versions with corrected licenses, and communicating transparently with affected parties."

Make sure to document every modification, including contributors and any licensing implications. This not only helps manage current issues but also creates a solid reference for future audits.

Communication is equally important. If violations impact released software, you may need to issue updated versions with corrected licenses and notify stakeholders. Being transparent demonstrates your commitment to compliance and can build trust – something that’s critical if legal disputes arise.

Addressing violations promptly doesn’t just reduce immediate risks; it also prevents the steep costs that come with prolonged non-compliance.

Costs of Non-Compliance

The financial consequences of non-compliance can be staggering. High-profile cases involving companies like SAP, Oracle, BMW, and Autodesk have highlighted the risks, with settlements averaging $14.82 million. Beyond financial penalties, companies also face operational disruptions and reputational harm.

Globally, the scale of unlicensed software use is immense. According to a 2020 report by the Business Software Alliance (BSA), the commercial value of unlicensed software reached approximately $46 billion. Violations not only strain relationships with vendors, customers, and partners but can also lead to more frequent audits and greater scrutiny from software providers.

Improving Your Compliance Program

Given the high stakes, refining your compliance program is essential. Start by maintaining a centralized inventory of licenses and actively monitoring their usage. This proactive approach can help prevent oversights and even cut costs by up to 30%.

License monitoring tools can track how licenses are used, helping you identify underutilized or overused licenses. Optimizing license usage not only ensures compliance but also reduces unnecessary spending. Gartner estimates that effective Software Asset Management (SAM) can slash software costs by as much as 30%[48].

Regular audits are another critical component. They provide real-time insights into how licenses are being used and ensure compliance with both commercial and open source standards. These audits should be comprehensive, covering all software types to avoid gaps in compliance.

The rewards of an effective compliance program are tangible. For example, Mitta Oy, a surveying and geotechnical consulting firm in Europe, cut its Autodesk licenses by up to 50% through better reporting and usage analysis. Similarly, Burns & McDonnell, a U.S.-based engineering and architecture firm, reduced its software spending by 25% by identifying underutilized licenses and optimizing costs.

Equip your teams with the right resources, such as license templates, FAQs, and guidance documents. Regular training sessions can also keep everyone up-to-date on licensing requirements.

Finally, consider the broader financial landscape. By 2025, global software spending is expected to surpass $1.2 trillion, reflecting a 14.2% year-over-year increase. At this scale, even small improvements in license management can lead to significant savings.

"In 2025, nominal spending versus real IT spending will be skewed, with price hikes absorbing some or all of budget growth."
– John-David Lovelock, Distinguished VP Analyst at Gartner

Conclusion

Managing dependency license compliance isn’t just a technical necessity – it’s a business imperative. With 97% of commercial codebases containing open source components, the challenge of maintaining compliance grows more complex every day, demanding a structured and proactive approach.

The numbers paint a stark picture: 56% of audited applications have license conflicts, and 33% include components with either no license or custom licenses. Even more concerning, 90% of applications rely on open source components that are over 10 versions out of date. These figures highlight the importance of staying vigilant and adopting a robust compliance strategy.

To address these challenges, organizations need to combine clear policies, automation, and ongoing monitoring into a cohesive compliance program.

FAQs

What are the risks of not complying with dependency license requirements?

Failing to adhere to dependency license requirements can lead to major legal and financial troubles. This might include lawsuits, steep fines, or even cease-and-desist orders tied to copyright violations. Beyond the immediate legal fallout, such problems can disrupt your business operations and tarnish your reputation, straining relationships with customers and stakeholders.

On top of the legal challenges, non-compliance can bring unexpected expenses, like replacing or reworking non-compliant dependencies. Staying on top of license compliance is crucial to sidestep these risks and keep your operations running smoothly without unnecessary interruptions.

How do tools like Software Composition Analysis (SCA) and Software Bill of Materials (SBOM) improve license compliance?

Automation tools like Software Composition Analysis (SCA) and Software Bill of Materials (SBOM) are game-changers when it comes to managing license compliance. They provide a clear view of your software components, making it easier to stay on top of requirements.

SCA is designed to pinpoint licensing conflicts and spot security vulnerabilities in open-source dependencies, giving you the chance to address issues before they escalate. On the other hand, SBOM works as a detailed inventory, listing all the components in your software. This makes tracking and meeting licensing obligations much more straightforward.

When used together, these tools streamline compliance efforts, minimize risks, and help ensure both legal and operational stability.

What’s the difference between permissive and copyleft licenses, and how do they affect software development and distribution?

Permissive licenses give developers a lot of freedom by allowing them to use, modify, and share software with very few restrictions. Unlike some other licenses, they don’t require derivative works to stay open source. This makes them a popular choice for commercial projects and proprietary software.

In contrast, copyleft licenses come with a key condition: any modified or derivative work must also be distributed under the same open-source license. This approach ensures that the software – and any changes made to it – remains free and open to everyone. While this promotes collaboration and transparency, it can make these licenses less appealing for commercial use.

These licensing differences shape how developers approach their projects. Permissive licenses are often chosen for proprietary software, giving teams the flexibility to keep their code private. Copyleft licenses, however, are perfect for those committed to keeping their work open and accessible to the broader community.
