Managed IT Services in New York City

Founded by former Stroz Friedberg leaders. 48 Wall Street, Suite 1100, New York, NY 10005.
Why Do New York Businesses Outgrow Their IT Support?
New York teams work across hybrid offices, home offices and client sites. Their data lives in dozens of SaaS apps, and their clients, regulators and insurers ask harder security questions every year.
Break-fix support and a single IT generalist can't keep up with that. Managed IT should keep people productive and keep the environment secure, at the same time.
Slow help desk response
Tickets sit while billable time drains away.
One-person IT
Coverage gaps when your IT person is out.
Security left to chance
An IT provider that doesn't see security as its job.
Hybrid Manhattan offices
Coworking, home and office networks all need support.
Client and insurer questions
Questionnaires your current provider can't answer.
Messy offboarding
Accounts and devices left active after people leave.
Do You Offer On-Site IT Support in New York City?
Yes. Most issues are resolved remotely, but our team works from 48 Wall Street and comes on site in Manhattan when hardware, networking or office work needs hands on the ground. Our New York office is staffed Monday through Friday, 9:00 AM to 6:00 PM ET, and the help desk is available 24x7.
Remote support around the clock, every day of the year.

Within a short period, they had assessed our needs, made clear recommendations, and helped us regain control of all our systems—hardware, software, and network infrastructure.
