Delaney Computer Services (DCS) has been a trusted managed IT, cybersecurity, and cloud services partner for businesses across the New York Metro area, Northern New Jersey, and South Florida since 1994. With a 99.999% client approval rating across more than 150 Google reviews, DCS helps small and mid-sized businesses reduce downtime, strengthen cybersecurity, modernize infrastructure, and manage the full lifecycle of business technology.
From its beginnings at the founder's kitchen table in 1994, DCS has grown into one of the most established managed service providers in the region. We work with organizations that need dependable business technology without the cost, risk, or complexity of building and managing an in-house IT department.

How We Work: Assess. Design. Build. Secure. Maintain.
Every DCS engagement follows the same five-step framework, whether we are stabilizing a new client environment, deploying a Microsoft 365 tenant, planning a cabling project, or building out a complete cybersecurity program. Cybersecurity and compliance are built into every step of the process, not bolted on at the end. Learn more about how DCS IT services follow this proven framework.
- Assess. We evaluate your current infrastructure, security posture, Microsoft 365 configuration, backup strategy, endpoint protection, network performance, compliance exposure, and user support needs.
- Design. We map solutions that fit your operations, budget, regulatory requirements, and growth plans.
- Build. We implement infrastructure, cloud platforms, and security tools with minimal disruption to your team.
- Secure. We harden every layer, including endpoints, identity, network, email, cloud, backups, and physical access.
- Maintain. We monitor, support, document, and continuously improve your technology environment over time.
Cybersecurity Is Built Into Everything We Do
Cybersecurity can no longer be treated as a separate add-on to business IT. Every company now faces risks from ransomware, phishing, credential theft, business email compromise, cloud misconfiguration, insider threats, and supply chain attacks. DCS integrates cybersecurity into the core of our managed services and infrastructure projects, helping clients strengthen protection across endpoints, networks, email, Microsoft 365, cloud platforms, backups, user access, and business-critical systems.
Our DCS Cybershield cybersecurity services deliver next-generation, AI-driven protection built on the same tools used by government, Fortune 500 companies, and military organizations, scaled and priced for the small and mid-sized business market. For organizations with regulatory obligations, our managed compliance services align IT operations with industry-specific cybersecurity frameworks and evolving mandates.

From Cabling to Cloud, DCS Connects the Whole Environment
A secure and reliable technology environment depends on more than software. Poor cabling, weak WiFi, aging switches, unmanaged network equipment, incomplete documentation, and fragmented vendors all create performance and security problems. DCS brings these pieces together: the cabling in the walls, the switches in the network closet, the wireless access points on the ceiling, the Microsoft 365 tenant in the cloud, the security tools protecting endpoints, and the support process users depend on every day.
This end-to-end capability is especially valuable during office moves, renovations, buildouts, acquisitions, expansions, cybersecurity upgrades, and modernization projects where multiple technologies must work together.
