Open Source Software (“OSS”) has become a foundational part of modern technology, powering everything from enterprise applications and cloud platforms to AI solutions. Yet, despite its widespread use many organizations still treat OSS as a developer tool rather than a business-critical dependency.
Open Source May Be Free to Obtain. But Is It Free to Manage?
Open Source Software has become part of everyday technology. Developers rely on it to accelerate delivery, while suppliers embed it into products and services. At the same time, cloud platforms, AI solutions, and enterprise applications depend on it behind the scenes.
Yet, despite its widespread use, OSS rarely triggers the signals organizations traditionally associate with software governance. There is often no purchase order. No invoice. No contract negotiation. No license key. And there is often limited or no footprint in SAM tools.
As a result, OSS can feel different from traditional software. It enters the organization quietly, spreads quickly, and often remains outside the visibility of Procurement, SAM, Legal, and other established governance functions.
This creates a common misconception: If nobody is paying for it, the risk must be low. The logic feels reasonable. After all, OSS is freely available, widely used, and supported by some of the world’s largest technology communities. As a result, organizations focus on the speed, flexibility, and cost advantages it brings and assume governance can come later, if needed.
But that misconception is exactly where the problem begins.
OSS May be Free to Obtain, But It is Not Free of Rights
In reality, obtaining Open Source Software may come at no cost, but using it can still introduce obligations.
An OSS component can introduce obligations, dependencies, and risks that organizations inherit the moment they use it. For example, a single library can bring license requirements. A transitive dependency can introduce a critical vulnerability. A supplier-delivered application can embed hundreds of open source components that the organization never directly selected.
Over time, this complexity grew because OSS has become a foundational part of modern technology. Organizations rely on it to accelerate development, modernize applications, support AI adoption, benefit from community-driven innovation and transparency, and reduce costs. In many environments, OSS is no longer the exception. It is the default.
That changes the governance challenge completely.
OSS is no longer just a development decision. It is a business dependency that influences security, compliance, procurement, legal exposure, supplier management, and operational resilience. Yet, many organizations continue to manage OSS as a technical concern rather than a strategic asset.
The result is a growing gap between the value OSS creates and the control organizations need to sustain that value.
OSS Bypasses Traditional Governance Signals
If the risks are real, why do so many organizations still treat Open Source Software as low risk? The answer is simple, because OSS rarely looks like a governance issue when it enters the organization.
It starts with perception. Most organizations associate software risk with familiar signals: contracts, invoices, vendors, renewals, and procurement processes. In turn, those signals naturally trigger reviews from Procurement, Legal, SAM, Security, and other governance functions, however, OSS bypasses most of them.
Developers download libraries in seconds. Package managers automatically pull in dependencies. Suppliers embed OSS into deliverables. Cloud platforms and AI solutions rely on it behind the scenes. As a result, OSS often enters the organization without triggering the controls traditionally used to govern software.
Then organizational dynamics take over.
Procurement sees no purchase. Legal sees no negotiated contract. SAM sees no traditional license or vendor-related software footprint. Meanwhile, security often becomes involved only after a vulnerability is discovered. As a result, each function sees part of the picture, but no single function owns the full lifecycle.
At the same time, human behaviour reinforces the problem.
Teams focus on the speed, flexibility, and innovation OSS enables. Governance feels like friction, while the risks remain largely invisible. As long as OSS continues to deliver value without creating immediate problems, organizations naturally assume existing controls are sufficient.
The result is a growing disconnect between adoption and governance.
OSS usage expands across applications, suppliers, cloud services, and development environments, while visibility, ownership, and accountability struggle to keep pace. Consequently, many organizations only discover the extent of their OSS exposure when a security vulnerability, license issue, supplier assessment, or regulatory requirement forces it into view.
Eventually, the consequences become impossible to ignore.
OSS Risk Becomes Business Exposure
Open Source Software creates value because teams can adopt it quickly, integrate it easily, and benefit from large developer communities. However, those same characteristics also make OSS difficult to control when governance fails.
The risks rarely appear on day one.
They accumulate quietly as OSS spreads across applications, cloud platforms, supplier solutions, AI-enabled development environments, and internal development teams. By the time organizations discover the issue, the impact often extends far beyond IT.
Three exposures appear repeatedly across organizations.
Security Exposure
Open source components sit at the heart of modern software. That scale creates enormous innovation potential, but it also creates a concentrated attack surface.
A vulnerability in a widely used component can affect thousands of organizations simultaneously. For instance, Log4Shell remains one of the best-known examples, demonstrating how a single open-source vulnerability can trigger widespread security incidents, operational disruption, and costly remediation efforts. More recent vulnerabilities, such as those affecting Apache Tomcat and popular npm packages, reinforce the same lesson: one vulnerable dependency can quickly become a business problem.
Furthermore, industry research highlights the scale of the challenge. Black Duck’s 2025 Open Source Security and Risk Analysis (OSSRA) report found that 86% of analysed applications contained vulnerable open-source components, while 81% contained high-risk or critical-risk vulnerabilities.
Therefore, the challenge is not finding vulnerabilities at once. The challenge is continuously monitoring them, prioritizing remediation, and assigning ownership before they affect critical systems.
License Compliance Exposure
Many organizations assume OSS licensing is straightforward because the software is free to download.
It isn’t.
Every component comes with a license, and every license introduces obligations. Some licenses are relatively permissive, others impose requirements related to attribution, redistribution, modification, or source code disclosure. For organizations looking to strengthen this area, integrating OSS license management into existing SAM practices can provide a structured approach to improving compliance and control.
As OSS estates grow, organizations often struggle to maintain visibility into which licenses apply, where components are used, and how software is distributed across products, services, and supplier ecosystems.
The consequences can be significant. For example, the Orange v. Entr’Ouvert case demonstrated that OSS license obligations are legally enforceable. In 2024, the Paris Court of Appeal awarded more than €800,000 in compensation, damages, and profit recovery linked to the misuse of GPLv2-licensed software.
The risk becomes even greater as OSS portfolios grow, and organizations introduce dual-licensed software, supplier-delivered solutions, and increasingly complex dependency chains.
Software Supply Chain Exposure
Modern applications rarely consist of isolated software components. Instead, they rely on complex networks of direct and transitive dependencies.
A single library may depend on dozens of additional components maintained by foundations, commercial entities, individual contributors, or communities with varying degrees of support and maturity. As these dependency chains grow, so does organizational exposure.
Recent industry findings illustrate the scale of this trend. Sonatype’s 2026 State of the Software Supply Chain report recorded 9.8 trillion open-source component downloads in 2025, representing a 67% year-over-year increase. In addition, the same report identified a 75% increase in open-source malware packages.
Organizations are no longer managing only their own software choices. They are inheriting risks from entire software ecosystems.
This challenge extends beyond internally developed applications. Suppliers, service providers, SaaS vendors, and platform providers increasingly embed OSS into their solutions, making supplier governance a critical part of OSS risk management.
The Common Thread
Security incidents, license disputes, and software supply chain risks rarely emerge because organizations intentionally accepted them.
Instead, they emerge because OSS usage outpaced governance.
Organizations cannot govern what they cannot see, and they cannot control what nobody owns.
That is why mature OSS governance goes beyond discovery tools and focus on governance. At enterprise scale, the risks become significantly harder to manage.
OSS Governance in Practice
Most organizations underestimate the scale of OSS in their environment until they attempt to govern it.
In practice, what we observe across large enterprise environments consistently surprises stakeholders: OSS is rarely limited to a handful of libraries or developer tools. Instead, it often represents a significant portion of the overall software estate and introduces governance complexity at a scale many organizations initially underestimate.
Scale
Enterprise OSS estates are often far larger than expected.
In organizations we have supported, software catalogues can contain more than 1,000 approved software products, with open-source accounting for nearly half of the portfolio. However, that is only the visible portion. The actual footprint is considerably larger once organizations account for embedded libraries within internally developed applications, commercially purchased software, cloud-native services, containers, AI solutions, and supplier-delivered platforms.
Moreover, industry data reinforces the same picture. Black Duck’s 2026 Open Source Security and Risk Analysis found open source components in 98% of audited codebases, while the Linux Foundation estimates that 70% to 90% of modern software solutions contain open source software.
The reality is simple: most organizations depend on far more OSS than they realize.
Complexity
Scale alone would be manageable. Complexity is what turns OSS into a governance challenge.
A typical OSS portfolio can include dozens of different license types. While permissive licenses such as Apache 2.0, MIT, and BSD often dominate, organizations must also manage reciprocal and copyleft licenses such as (A)GPL and EPL. In addition, they may need to account for commercially supported open source distributions like Elasticsearch or PostgreSQL.
Even software composition analyses performed on only a small number of internal applications frequently identify thousands of individual software components and dependencies. Many of these components require further investigation to determine ownership, risk, or license obligations.
Furthermore, regulatory developments add another layer of complexity. Frameworks such as the Cyber Resilience Act (CRA) and NIS2 raise expectations around software supply chain transparency, vulnerability management, and accountability. As a result, organizations face increasing pressure to govern OSS effectively.
Consequences
When governance fails, the impact extends beyond technical complexity.
Open-source license obligations are enforceable. For example, the Orange v. Entr’Ouvert case as mentioned above, demonstrated that organizations could face significant financial consequences when they fail to comply with OSS licensing obligations.
Another example where we observed dual licensing enforcement activity (AGPL/commercial licensing) in the market, relates to Apryse’s iText PDF library. And they are merely some examples.
These have prompted organizations to reassess architectures, licensing decisions, and software usage when compliance reviews uncover previously unmanaged OSS dependencies.
Some organizations struggle to manage this complexity. Others build governance around it.
What Mature Organizations Do Differently?
Mature organizations do not treat OSS as a development tool. They treat it as a governed business dependency.
They understand that discovery does not create control. Governance does.
Rather than managing OSS through isolated activities, mature organizations connect Security, Legal, Procurement, SAM, Architecture, Development, and supplier management around a shared view of ownership, risk, and accountability. In practice, these governance functions are often – but should not necessarily be – chaired by an overarching Development Management team (e.g. DevEx, DevSecOps) or Asset Management team (e.g. SACM, SAM…).
In practice, this means:
- Maintaining visibility into OSS across applications, cloud platforms, AI-enabled development environments, and supplier-delivered solutions
- Assessing license obligations before they become legal, contractual, or commercial issues
- Monitoring vulnerabilities continuously and assigning clear remediation ownership
- Extending governance beyond internal development to suppliers, service providers, and technology partners
- Incorporating OSS considerations into procurement, architecture, security, and lifecycle decisions
Mature organizations understand a simple principle: Open-Source Software creates value through adoption, while governance ensures that value remains sustainable. Ultimately, the difference comes down to a few practical governance disciplines.
Practical Governance Actions
Organizations do not need to slow down open source usage. They need to make OSS visible, owned, and governed throughout its lifecycle.
1. Build Visibility
Create an OSS inventory that covers internally developed applications, supplier deliverables, cloud platforms, containers, AI-generated code, and third-party software. Without this baseline, Legal, Security, Procurement, and SAM teams cannot assess exposure or prioritize action. Although, many organizations already have some level of visibility through software composition analysis (SCA) tools and other scanning capabilities, the challenge is consolidating that information and turning it into actionable insight. Without this baseline, Legal, Security, Procurement, and SAM teams cannot assess exposure or prioritize action.
2. Assign Ownership
Define clear decision rights across Development, Security, SAM, Procurement, Legal, Architecture, and supplier management. Each function contributes a different perspective, but effective governance requires a shared operating model that connects license compliance, vulnerability management, supplier accountability, and commercial decision-making.
3. Govern Suppliers
Extend OSS governance beyond internal development. For example, consultancy agreements, services contracts, and software delivery agreements should include OSS disclosure requirements, compliance obligations, and remediation responsibilities. Organizations need visibility into the OSS embedded within supplier-delivered software, not just the OSS they introduce themselves.
4. Monitor Continuously
OSS governance is not a one-time approval activity. Components, licenses, vulnerabilities, maintainers, and commercial models evolve continuously. Therefore, organizations need recurring reviews that connect technical findings with legal assessment, security prioritization, procurement action, and business ownership.
The Leadout Perspective
At Leadout, we see OSS management as a strategic capability, not a technical clean-up exercise. The objective is not to restrict OSS adoption, but to help organizations use open source securely, compliantly, and at scale.
We support organizations across the OSS lifecycle, from governance design and supplier requirements to license compliance, risk assessments, and ongoing oversight.
For example, our Sourcing, Procurement & Vendor Management experience facilitates embedding OSS expectations into consultancy agreements, service contracts, and software delivery arrangements. As a result, suppliers and partners understand their responsibilities from the outset.
At the same time, our experience in Software Asset Management and technology governance allows us to translate OSS findings into business decisions. Identifying a component, license obligation, or vulnerability is only the beginning. Ultimately, the real value comes from understanding ownership, assessing impact, and defining the right course of action.
Most importantly, we help organizations connect the stakeholders involved in OSS governance. Security, Procurement, Legal, SAM, Architecture, Development, and Supplier Management each own part of the picture. By bringing these perspectives together, Leadout helps create a practical governance model that remains effective as OSS usage continues to grow.
Key Takeaways
- OSS is already in your environment. The real challenge is how to govern it.
- OSS brings speed, innovation, and cost efficiency, but it may also create legal, security, operational, and commercial exposure when organizations lack governance.
- Traditional IT and SAM alone are not enough because OSS is embedded in code, introduced by multiple teams, and constantly evolving.
- Tools can detect OSS, but governance turns visibility into ownership, lifecycle control, procurement action, and business decisions.
- Strong OSS governance helps organizations reduce risk, avoid hidden costs, strengthen supplier accountability, and keep innovation scalable.
- Open-Source Software is free to obtain. But it is not free to ignore. Ultimately, organizations that fail to govern it often discover the cost much later.
