Westchester County & Fairfield County — Where PCI Works
From Yonkers to Greenwich, from IBM’s Armonk campus to Sikorsky’s Stratford plant, Performance Connectivity provides managed IT, cybersecurity, and compliance services to the businesses that define this region’s commercial character. This is our territory — not a coverage map on a website, but the communities we operate in every day.
What Businesses Across This Region Ask Us
Why does it matter that my IT provider is local to Westchester and Fairfield County?
Because IT problems do not respect business hours or remote access limitations. When something is genuinely broken — a server down before a critical presentation, a security incident unfolding in real time — the provider who can be at your location within the hour is worth more than the one remoting in from three states away. PCI is headquartered in Purchase, NY. We are in this market, not distant from it.
We have locations in both Westchester and Fairfield County — can one provider cover both?
Yes, and it is the right approach. Consistency of standards and monitoring across both states is important — your security posture should not vary based on which office your staff is working from. We manage multi-site environments across the CT-NY border regularly and apply the same rigor everywhere.
How do you approach the compliance differences between New York and Connecticut regulations?
With direct knowledge of both. NYDFS Part 500 applies to NY-licensed financial services entities; Connecticut has its own data security law. For businesses operating across both states, the frameworks are different enough to require a provider who knows both — and similar enough that a well-designed compliance program satisfies much of each. We navigate this for clients every day.
The Commercial Geography We Serve
Westchester County and Fairfield County share a border, a commuter railroad, and a commercial economy that functions as a single extended market. They do not share a regulatory environment, a business culture, or a uniform set of IT challenges. What works for a hedge fund in Greenwich is not the same conversation as what works for a defense contractor in Stratford or a professional services firm in White Plains.
PCI serves this geography with that specificity in mind. We do not run one playbook for every client. We run the playbook that fits your community, your industry, and your actual risk profile.
Westchester County — Seven Distinct Markets
Westchester is not a monolith. The commercial density of Yonkers is not the same as the corporate campus environment of Armonk, and neither resembles the affluent professional practice market of Bronxville. Each community has its own character, its own primary industries, and its own IT challenges.

Fairfield County, CT — Three Distinct Markets
Fairfield County spans from Greenwich’s financial intensity to Stratford’s defense manufacturing heritage. These three markets have almost nothing in common in terms of industry mix, regulatory exposure, or IT requirements — which is precisely why cookie-cutter IT support fails them.
What PCI Brings Across the Entire Territory
Managed IT & Cybersecurity
Endpoint management, Microsoft 365 administration, network security, and rapid response for every business in our coverage territory. We manage your environment so your staff does not have to.
Compliance Programs
NYDFS Part 500, SEC Reg S-P, HIPAA, NY SHIELD Act, CMMC, SOC 2 readiness, cyber insurance preparation — we navigate the full compliance landscape for businesses across both states and help you build toward the frameworks that apply to you.
AI & Automation Readiness
Microsoft Copilot, AI-assisted workflows, and process automation require the right governance and security foundation. We help businesses adopt AI tools with the structure that makes adoption sustainable — not a liability.
Technology Advisor
Technology decisions have strategic consequences. PCI’s leadership team provides technology advisor support to our client portfolio — helping businesses think through technology investments, vendor selection, and IT strategy with the same rigor they bring to every other business decision.
