What Kelser Corporation does

Kelser Corporation is a privately held managed IT services provider (MSP) headquartered in Glastonbury, Connecticut, operating continuously for more than 40 years (founded circa 1981–1985). The firm delivers outsourced and co-managed IT support to small and mid-sized organizations across Connecticut and Massachusetts, with primary vertical concentration in healthcare, manufacturing (including Defense Industrial Base contractors), and nonprofits, and secondary coverage of insurance, higher education, legal, construction, and financial services. The service stack is built on a managed services platform combining remote monitoring and management (RMM), endpoint security agents, SIEM, multi-factor authentication, email authentication (SPF/DKIM/DMARC), network segmentation, secure backup, business continuity/disaster recovery, and conditional access for Microsoft 365, augmented by an Authorized Apple Partner practice.

The business model centers on recurring monthly managed services subscriptions (Fully-Managed and Co-Managed IT) bundled with a vCIO strategic guidance engagement and a Technical Alignment Manager per client, plus project-based cybersecurity and compliance services for HIPAA, NIST 800-171, and CMMC 2.0. Hardware procurement and lifecycle management (including Apple-authorized supply chain) and strategic IT consulting (data center, cloud, network redesign) round out the revenue mix. GTM is consultative and VP-led (no sales reps), driven by an extensive content/SEO engine (~129+ blog pages), free self-service diagnostic tools (Kelser Score, CMMC Readiness Score Tool), chamber and consortium memberships (CTGLC, MetroHartford Alliance, Naval & Maritime Consortium, Tech Data TechSelect), and a Partner Referral Program. The company is recognized across multiple consecutive years on CRN Solution Provider 500 (2013–2019), CRN MSP 500 (2017–2020), CRN Tech Elite 250 (2016, 2020, 2021), and the CRN Triple Crown (2020), and operates the affiliated Kelser Foundation which runs the 28-year annual Kelser Charity Challenge (record $58,000 donation in February 2025).

Product overview

Kelser Corporation offers a platform-plus-modules portfolio rather than a single unified software product: the core engagement is its Fully-Managed IT Services offering (with a parallel Co-Managed IT Services track for organizations with internal IT teams), delivered as proactive monitoring, patching, helpdesk support, and vCIO strategic guidance to Connecticut and Massachusetts small-to-medium businesses, healthcare providers, manufacturers, and nonprofits. Layered on top of that managed-IT core are specialized service modules including Managed Cybersecurity Services, CMMC Compliance Support, NIST 800-171 Compliance Support, Business Continuity & Disaster Recovery, Data Center Services, Managed Network Services, and Supply Chain Services, along with an Authorized Apple Business Solutions practice. Industry-specific service lines extend the same core into Healthcare, Manufacturing, Nonprofit, Construction, Financial, Higher Education, Insurance, and Legal IT Consulting. Customer-facing self-service tools sit alongside the services portfolio, including the Kelser Score (a 3-minute IT support diagnostic) and the Kelser CMMC Readiness Tool paired with the CMMC 2.0 Compliance Forward readiness plan for defense industrial base clients.
