- Consulting services: An IT company often provides experts to advise on implementing new technologies, optimizing business processes, or selecting appropriate technological solutions.
- Cloud solutions: Many IT companies specialize in implementing and managing cloud solutions, such as data storage, application hosting, and data analysis platforms.
- IT security: Protection against cyberattacks, security audits, implementing security policies, and network monitoring are just some of the IT companies' responsibilities in this area.
