What is FOSS?

Free and Open-Source Software (FOSS) allows anyone to run a program for free and for any purpose they wish. It also allows the user to access the source code, modify it and redistribute either the original or the altered version.

FOSS is increasingly being used in business operations because it enables new software developments to be implemented at a faster pace and a lower cost than writing it in-house. FOSS gives businesses access to the latest software, which they can then use to enhance their own offerings.

While FOSS is free to use, this does not mean that users have no obligations. When the original developer makes their FOSS products available, they may choose to use a FOSS licence, which defines what can or cannot be done with the source code. For example, they may stipulate that anyone who modifies the software must make their modifications available for anyone else to use.

Companies using FOSS are subject to a variety of licence agreements. To maintain compliance and avoid liabilities, these licences must be managed in a structured manner. This requires policies and procedures, the identification of roles responsible for its management, as well as effective skills management and a training strategy.


FOSS licence compliance is an essential element of regulatory, legal and corporate compliance. Proof of FOSS compliance is increasingly a requirement for software vendors during the contract tender process. Failure to comply can also be very damaging for a business's reputation in the open source community.

FOSS compliance verification is therefore a critical factor for the sale of products that integrate FOSS, and for companies seeking to establish partnership-based collaboration. To prevent infringements of licensing agreements, businesses must establish a suitable process for guaranteeing and verifying compliance.
