Managed IT for Accounting Firms in Brooklyn
Accounting and fiduciary firms hold exactly what attackers want: financial records, identities, and the authority to move money. Two Brooklyn engagements below show both ways firms work with us — full protection under management, and a clean one-time migration for a firm with its own IT.
The short answer
NetSys provides managed IT and cybersecurity to accounting, fiduciary, and CPA firms in Brooklyn: security stacks configured to the firm rather than installed from defaults, ransomware recovery planning, cloud migrations executed without data loss, and either full management or project work alongside internal IT. Our headquarters is in the borough, at 1 Prospect Park SW.
A fiduciary firm protected; an accounting firm migrated
The first client is a 14-seat Brooklyn fiduciary firm whose matters carry substantial monetary value. The second is a Brooklyn accounting firm with its own internal IT team that needed a one-time move to the cloud done right.
The fiduciary firm needed its files defended and a real ransomware recovery plan — their exposure is measured in what they safeguard for clients, not in their own headcount. The accounting firm needed on-premises infrastructure retired and everything moved to the cloud without disrupting a working office.
What NetSys did
- Fiduciary firm: Microsoft Defender, Barracuda, and Rapid7 deployed and configured specifically for the organization
- Fiduciary firm: file protection and a ransomware recovery plan built around their obligations
- Accounting firm: a planned OneDrive and Azure migration from on-premises, executed over a few weeks
- Accounting firm: cybersecurity and ransomware recovery plan handed to their internal IT, with NetSys on call for larger-scale issues
The results, as measured since onboarding
- Fiduciary firm: zero incidents and 100% uptime since NetSys came on board
- Accounting firm: on-premises to cloud with a working plan and a clean cutover — and an ongoing relationship on the issues too big for one internal tech

Brooklyn firms, borough-based support
Both engagements above are Brooklyn businesses supported from a Brooklyn headquarters. For a fiduciary or CPA firm, that means an engineer can be physically present for the conversations that shouldn't happen over a ticket — security reviews, tax-season readiness, the annual look at what's changed.
Everything else about how we serve the area — coverage, on-site cadence, and the honest answer about where our office is — lives on our Brooklyn location page.
Accounting Firms in Brooklyn: FAQs
Do you work with firms that already have internal IT?
Yes — one of the two engagements on this page is exactly that. Their team runs the day to day; we executed the cloud migration, built the security and ransomware plan, and stay on call for anything larger than one person should carry alone. Co-managed arrangements like this are a standing NetSys service, not an exception.
What security stack does an accounting firm actually need?
Configured beats installed. For the fiduciary firm here that meant Microsoft Defender, Barracuda email protection, and Rapid7 — each set up for the firm's actual workflows and obligations rather than left on defaults. The IRS also requires a Written Information Security Plan for tax professionals; our WISP guidance covers what belongs in it.
Can you keep an accounting firm running through tax season?
That is the design constraint for everything we build in this vertical: migrations scheduled around deadlines, monitoring that catches failures before Monday morning, and recovery plans measured in hours. The fiduciary engagement on this page has run at 100% uptime since onboarding.
