IT Services for NYC Commercial Real Estate
Managed IT, wire-fraud protection, and platform integration for NYC and NJ brokerages, property managers, developers, and REITs — built around the transaction realities and mobile workforce of commercial real estate.
Get a Free IT AssessmentReal estate sits at the intersection of two high-risk realities: massive transaction values moving through email, and a mobile workforce spread across dozens of properties. The FBI consistently reports business email compromise in real estate as the single largest source of reported cybercrime losses by dollar volume. A single fake wire-instruction email can cost a client $300K+, and once funds leave, recovery is rare.
What that actually requires: hardened email and wire-verification protocols, secure remote access for brokers and property managers working from sites, cars, and home, MLS and CRM integration (CoStar, REBNY RLS, Apto, Buildout) without security gaps, property management platforms (Yardi, AppFolio, MRI, RealPage) that need real integration, tenant data protection under NY SHIELD Act, and segmented networks for building IoT systems. InterDataLink supports NYC and NJ brokerages, property managers, developers, and small REITs.

Anatomy of a Real Estate Wire Fraud Attack
The single largest source of reported cybercrime losses in real estate. Here’s how the attack actually unfolds — and how InterDataLink breaks the chain.
Reconnaissance · weeks before closing
Attacker compromises a broker, agent, or attorney’s email. Reads the transaction thread to learn the deal, parties, timing, and language patterns.
Domain spoofing · days before closing
Registers a look-alike domain (e.g. firstrate-realty.co vs. firstrate-realty.com). Sets up email visually identical to the legitimate party.
Spoofed wire instructions · hours before funds move
Sends an “updated wire instructions” email from the spoofed domain. Indistinguishable from the real broker’s correspondence.
Funds vanish · minutes after the wire clears
Buyer wires $400K–$2M+ to the attacker’s account. By the time the broker realizes what happened, funds are gone. FBI BEC recovery rate is under 14%.

Frequently Asked Questions
How do you protect against wire fraud during closings?
Multiple layers. First, email security: advanced BEC detection that flags look-alike domains, DMARC/SPF/DKIM hardening against spoofing, and email encryption for sensitive correspondence. Second, secure client portals so wire instructions never travel in raw email. Third, written verification protocols built into your workflow: any wire instructions are confirmed by a known phone number before funds move. Fourth, training so your brokers and admins recognize the specific patterns of real estate BEC attacks.
Do you integrate with CoStar, REBNY RLS, Yardi, AppFolio, or other real estate platforms?
Yes — these are common in our real estate client base. We’ve handled installs, single sign-on integration, mobile sync, and ongoing administration across CoStar, REBNY RLS, LoopNet, Apto, Buildout, Yardi, AppFolio, MRI, Buildium, and RealPage. If your firm uses something less common, we’ll tell you whether we have direct experience or will need to ramp.
Can you support a multi-property portfolio with on-site staff at each location?
Yes. Centralized IT management with site-local support is exactly what property management firms need. Each property gets standardized network gear, monitored remotely. On-site staff get help desk access with priority routing. Hardware replacement and break-fix dispatch are scoped per property. Tenant-facing systems (wifi, access control) are segmented from your management network.
What about IoT and building systems — cameras, smart locks, BMS?
Building IoT is one of the biggest under-secured surfaces in commercial real estate. We segment these onto isolated networks so a compromised camera can’t pivot into your management systems. We monitor uptime so recording gaps don’t become liability issues. We work with your access control and BMS vendors for integration, but keep the network layer separate. For older buildings adding IoT, we plan the network architecture before equipment goes in.
How do you handle tenant data under the NY SHIELD Act?
The SHIELD Act requires reasonable administrative, technical, and physical safeguards for private information. For real estate firms holding tenant SSNs, income verification, and bank info, we implement: encryption for stored tenant data, role-based access so only authorized staff can view, audit logs of access, and breach notification protocols. We also document the safeguards — SHIELD Act compliance includes having a written program, not just controls.
