Cybersecurity & Managed IT in Scarsdale
Scarsdale's village offices serve some of the country's most concentrated household wealth — the accountants, attorneys, advisors, and family offices trusted with it work steps from the Metro-North platform. NetSys serves clients across Westchester County today, and runs the kind of practice this town hires: quiet, careful, and documented.
The short answer
NetSys provides cybersecurity, managed IT, and AI automation to Scarsdale businesses: multifactor authentication and conditional access, managed endpoint detection and response with 24/7 monitoring, email defense tuned for principal impersonation and wire fraud, Microsoft 365 management with independent backup, immutable disaster recovery, penetration testing, vCISO leadership for family offices and advisory firms, and in-house AI automation. Westchester County is a named on-site coverage area where NetSys already serves clients. Our only office is in Brooklyn — no Scarsdale address claimed, and none needed for engineers to reach the village.

Protecting practices whose clients are the target
Attackers rarely start with a Scarsdale advisor's systems; they start with the advisor's clients — impersonating principals, intercepting distributions, forging instructions. Defense has to cover both directions: hardened identity and monitored endpoints inside the practice, and money-movement procedures that force human verification no matter how convincing the email. We write those procedures with you, then run the systems that back them.
Small-office IT without the small-office fragility
A five-to-twenty-person practice can't absorb a down day during tax season or a closing. Managed IT removes the fragility: 24/7 monitoring that catches failures early, patching on schedule, documentation that survives any one person's vacation, backups restored on the record, and a help desk where the voice on the line already knows your setup.
Discretion, stated as policy
Our financial and fiduciary clients have never been named on this site — no logos, no testimonials with attribution, no case-study cameos. Scarsdale practices extending that same discretion to their clients tend to recognize the policy for what it is: part of the service, not a gap in the marketing.
A therapy group with notes in too many places
A composite example of work we do, written so you can picture the first 90 days. It is not a specific client — our real, named engagements are in case studies.
A behavioral health group runs sessions in the office and from home. Session notes had drifted onto personal laptops and into email drafts, and the clinical director knew it. The group needed remote work to keep working without ePHI scattering across devices nobody manages.
- A HIPAA security risk assessment focused on the remote setup, not a generic checklist
- Conditional access in Microsoft 365 so clinical systems open only from screened devices
- Session notes moved into the EHR and off laptops, with stray local copies found and removed
- Encrypted email for anything touching patient information
- Short training for clinicians on the specific habits that put notes where they should not be
Therapists still work from home. The notes no longer do. The risk assessment is written and dated, and repeating it next year is already scheduled.

Scarsdale, NY FAQs
Do you work with family offices in Westchester?
Yes — the family-office profile fits our vCISO-plus-managed-IT model precisely: institutional risk carried by a very small team. We run the daily stack, add the policy, vendor-risk, and reporting layer above it, and never name the engagement anywhere. Westchester County is active on-site coverage for us today.
What does 'evidenced' security actually mean for a small practice?
That every control can prove itself: MFA enrollment you can export, restores with dates and durations, access reviews with sign-offs, an incident plan with a revision history. It matters because the people who ask — carriers, custodians, sophisticated clients — have stopped accepting reassurance. Building evidence in from the start costs little; reconstructing it under deadline costs credibility.
Can you support a practice through a generational or partner transition?
Transitions are when undocumented IT becomes expensive: accounts nobody can access, systems nobody understands, licenses in a founder's personal name. We document the environment, move ownership to the firm rather than any individual, and manage access changes cleanly. It's unglamorous work that every succession plan quietly depends on.
