Exploring the Benefits and Risks of Outsourced IT

Hello all,

I’m evaluating third-party support options and came across a service offering Managed IT Services for IT Departments. In your experience, what are the biggest advantages and pitfalls when integrating such services into an existing IT team?

For instance:

How do you manage ownership of critical infrastructure (networks, servers, security)?

How does communication with vendors and internal staff shift?

Can it lead to knowledge loss among in-house staff?

Any real-world stories, lessons learned, or best practices are much appreciated!
