Proactive IT Services & IT Support Connecticut Businesses Trust

Kelser supports small to mid-sized businesses, healthcare providers, manufacturers, and nonprofits in Connecticut and Massachusetts. We offer both fully managed IT services, co-managed IT support and cybersecurity and compliance services.

Yes. Our dedicated cybersecurity and compliance team helps your business get the full support it needs for NIST, CMMC, and HIPAA including gap analysis, remediation support, documentation, and audit preparation.

When you reach out and book a consult, you'll speak directly with our VP of Revenue and VP of Strategic Services - no sales reps. Our goal is to understand your business, discuss your biggest IT challenges, give you insights before you make any decisions, and see if we are a good fit to work together. It's an open, no-pressure or obligation conversation focused on helping you find the right IT support so your business can move forward. You’ll walk away with actionable recommendations, even if we don’t work together.

For more than 40 years, our mission has been to provide local, white-glove IT support for Connecticut businesses by being more proactive than any other MSP in the state.

Partnerships with our clients are built on personalized, industry-focused strategies that go beyond basic help desk support. We become a long-term partner who takes ownership of eliminating IT issues altogether, so you can stay focused on running and growing your business.

Many clients immediately notice the difference like personalized service, faster response times, reduced downtime, and fewer help desk tickets. By your first quarterly business review (around 90 days), you’ll see clear measurable performance metrics and data that shows improved operations, stronger security, and peace of mind knowing your IT just works.

Kelser primarily serves Connecticut-based organizations, but we also support clients across Massachusetts. Our local team ensures white glove on-site availability when needed and remote support that always feels personal and responsive.

Proactive IT means your technology partner prevents problems instead of just reacting to them. To do this, we continuously monitor your network, apply patches, and provide strategic IT guidance to understand your business, prevent downtime, security incidents, and compliance risks before they impact your business.

Managed IT Services pricing depends on several factors including your IT environment, number of users, and business goals. We’re one of the few IT providers that offer both a pricing page and a quick self-service calculator, so you can see exactly what proactive IT support might cost for your business.
