Many companies that are new to the open-source community make the mistake of publishing their code and leaving it behind. Issues are left unresolved and unanswered, road maps are not shared, pull requests are ignored, and there is no way to get in contact with the people behind the project. As much as open-source projects can enhance your technical brand, leaving projects in this state can hurt it.
Once you’ve open-sourced a project, you must commit to maintain it. Even stable software will have bugs, and some of those bugs could be found by people outside of your company. If you have no intention of interacting with anyone outside of the company on this project, then you might want to consider simply distributing the compiled binary or library freely, and not actually open-sourcing the code.
