IT Consulting in Maryland
Not every business needs a fully managed IT plan. Sometimes you just need an experienced consultant to look at your setup and tell you what to fix first. That’s the IT consulting side of ICSI, and we’ve been doing it for Maryland businesses since 1987 from our office in Annapolis.
Our consultants help with network design and office moves, cloud and Microsoft 365 planning, disaster recovery and business continuity plans, and network security. We work with medical practices, non-profits, real estate offices, construction firms, consulting agencies and engineering groups across the state.
Every project starts with a free IT assessment. We look at what you have now and where your business is heading, then give you a clear plan before any work begins. If you’d like us to look after your systems day to day after that, we can take it on through our managed IT services.
