Co-managed IT services give internal technology teams access to outside specialists without handing over the entire IT function. The companies below support different versions of this model, from help desk and infrastructure management to cybersecurity, cloud operations, application support, and specialist engineering. The right fit depends on which responsibilities a company wants to retain internally and which areas need additional capacity or expertise.
Gilzor works with internal product and technology teams that need additional engineering capacity around existing software. Its development support service can start with an audit of in-house specialists, code, technologies, and development processes, followed by workflow improvements, technical work, training, or a dedicated support team. Gilzor also supports products after launch and can take over platforms originally developed by another provider. This structure is relevant when a business wants to keep product ownership internally while adding external developers, QA specialists, cloud expertise, and ongoing maintenance capacity.

Co-managed IT services give companies a practical way to strengthen internal technology teams without fully outsourcing IT operations. Depending on the provider, support can cover help desk operations, infrastructure management, cloud environments, cybersecurity, monitoring, application support, compliance, and strategic planning.
The most suitable model depends on which responsibilities should remain in-house and where additional expertise or capacity is needed. Companies should compare service scope, escalation processes, SLA structure, security capabilities, cloud expertise, and the provider's ability to integrate with existing tools and workflows before choosing a partner.
