Co-managed IT services (or hybrid IT services) is when you use a managed service provider (MSP) to supplement your in-house IT staff. Co-managed IT services can be the best of both worlds if your business is large enough to maintain an in-house IT team. You decide how much you want in-house and what you want from an MSP. Here’s how it could work: Day-to-day business is handled by your in-house IT team with assistance or specialized expertise from your managed service provider as needed. Your MSP serves as a virtual chief information security officer or VCISO, basically becoming an outsourced CTO. Your internal IT team manages your systems and implements strategies created under the expert direction of your MSP. Your IT leadership is in-house but an outsourced managed IT team executes and manages your systems day to day.
