New York City law firms handle some of the most sensitive data in the world — privileged communications, merger and acquisition details, litigation strategy, and client personal information. Protecting that data isn't just an ethical obligation; it's a business necessity in a city where a single data breach can end client relationships and trigger malpractice exposure. Zerosums Technologies provides managed IT services and cybersecurity designed specifically for NYC law firms. We understand the New York State Bar Association's cybersecurity guidance, ABA Formal Opinion 477R on protecting client information, and the practical IT challenges of running a legal practice — from managing high-value document workflows to enabling secure remote access for attorneys working across multiple locations. Our law firm IT services cover the full stack: Microsoft 365 for legal (including Teams for client communication, SharePoint for matter management, and Exchange Online security), endpoint protection for attorney devices, secure remote access, email encryption, and multi-factor authentication. We also implement data loss prevention (DLP) policies that prevent inadvertent disclosure of privileged communications. For NYC law firms preparing for client security audits — increasingly common for firms handling institutional clients in financial services and healthcare — we produce compliance documentation that demonstrates your security controls. We also support cyber insurance underwriting and help firms meet the security requirements of their most demanding clients.
