What we do
End-to-end systems design
From architecture planning to 24/7 operations support, we handle the full lifecycle of your technology infrastructure.
Cloud Infrastructure
Multi-cloud and hybrid deployments engineered for performance and cost efficiency. AWS, GCP, Azure — we architect across providers so you are never locked in.
Cybersecurity
Threat modeling, penetration testing, and continuous monitoring. We treat security as a design constraint, not an afterthought — built into every layer of the stack.
Managed Operations
Around-the-clock monitoring, incident response, and proactive maintenance. Our NYC-based operations desk keeps your systems healthy so your team can focus on the mission.
How we work
A process tuned to your reality
No rigid playbooks. Every engagement starts with listening and ends with a system your team can own.
Discovery and assessment
We map your current architecture, interview stakeholders, and identify constraints — technical, financial, and operational. Expect a clear picture of where you stand within the first week.
Architecture and design
We produce detailed system blueprints with trade-off analysis. Every recommendation includes the why — not just the what — so your team can evaluate options with confidence.
Implementation and migration
Phased rollouts with rollback plans. We build, test, and deploy in incremental stages, keeping your existing systems running throughout the transition.
Handover and support
Documentation, runbooks, and knowledge transfer sessions. We stay engaged through a transition period until your team is fully self-sufficient — and we remain on call afterward.
NYC-born, infrastructure-obsessed
Plaza Tech operates under Concourse Tech Inc., headquartered at 169 Madison Avenue in the heart of New York City. We serve organizations that depend on always-on infrastructure — financial services, healthcare, logistics, and enterprise SaaS.
Our team brings decades of combined experience across systems engineering, network architecture, and security operations. We do not resell cookie-cutter solutions. Every system we design is built to fit the organization it serves.
