What Corstar Communications does

Corstar Communications LLC is an independently owned managed IT services provider headquartered in Hawthorne, New York. It serves small and mid-market businesses across the New York tri-state area, with an emphasis on small businesses with 5-75 employees and vertical expertise in healthcare, financial services, legal, and professional services. Its core managed IT offering combines 24/7 network and server monitoring, help desk support, cybersecurity, Microsoft 365 and Azure management, cloud backup, compliance controls, and on-site support under a flat per-user monthly fee.

Around that recurring base, Corstar sells cloud migration, disaster recovery, backup and storage, compliance, penetration testing, network optimization, remote-office support, structured cabling, and project implementation. Its technical stack includes remote monitoring and management, endpoint detection and response, managed firewalls, DNS filtering, BeyondTrust remote support, and integrations with Microsoft 365, Azure, Epic, Athena, eClinicalWorks, NetDocuments, iManage, and Worldox. These services target regulated and data-sensitive organizations requiring availability, confidentiality, and compliance support.

Corstar's primary revenue stream is managed IT sold as a flat per-user monthly subscription, commonly priced at $80-$150 per user per month, with standard annual agreements; project implementation, structured cabling, and penetration testing generate professional-services revenue. Go-to-market is direct and consultative, using free 30-minute IT assessments, phone and email inquiries, website forms, and Microsoft Bookings. AI Deployment & Management extends the offering into governed access, shadow-AI identification, business-system integration, and agentic tooling delivered through OpenAI and Claude partner relationships. The company reports 500+ businesses served over its history and 24/7 monitoring, but it does not disclose current revenue, active customers, or customer-level concentration.

Direct peers

• Dataprise: Mid-Atlantic-based managed IT services provider serving SMB and mid-market clients with 24/7 help desk, cybersecurity, and cloud management. Comparable to Corstar in service scope and customer profile, though materially larger.
• Ntiva: Regional MSP offering managed IT, cybersecurity, cloud, and compliance services to SMBs across the Mid-Atlantic and beyond. Direct competitor for managed IT per-user contracts and a useful benchmark for regional MSP scale.
• CMIT Solutions: Franchise-based managed IT services network targeting SMBs with proactive monitoring, cybersecurity, and help desk. Closely comparable business model and customer segment to Corstar's Westchester SMB focus.
• BlackPoint IT Services: Regional managed IT and cybersecurity provider serving SMB clients with proactive monitoring and compliance support. Comparable in size, service mix, and customer profile to Corstar.
• NerdsToGo: Franchise small-business IT support provider delivering on-site and remote managed IT, networking, and cybersecurity to SMBs. Comparable customer profile (5–75 employees) and recurring per-user pricing model.

Broad incumbents

• Secureworks: Global MDR/cybersecurity incumbent that competes with MSPs offering bundled EDR/SOC services. Relevant incumbent comparison for Corstar's cybersecurity-bundled-in-base-plan positioning.
• Kaseya: Large incumbent provider of RMM, PSA, and security platforms purpose-built for MSPs. Corstar likely runs on a Kaseya-style RMM stack; the platform powers much of the SMB MSP ecosystem and represents indirect competitive pressure on services Corstar delivers.
• ConnectWise: Broad incumbent IT management platform vendor serving managed service providers with PSA, RMM, and cybersecurity tooling. Comparable to Corstar only at the tooling layer but shapes the broader SMB MSP competitive landscape.

Others

• Pax8: Cloud distribution and managed services platform enabling MSPs to procure and provision Microsoft, security, and SaaS solutions. Indirect ecosystem peer — Pax8's partner programs shape how Corstar and similar MSPs source and bundle cloud services.
