Cybersecurity for:
Real Estate & Building Management

Why is the real estate sector a target for cyberattacks?

The real estate industry is undergoing digital transformation — modern office buildings and residential complexes are smart buildings with thousands of IoT sensors, BMS (Building Management Systems), intelligent elevators, and HVAC automation. Each of these devices is a potential entry point into the building’s network. Simultaneously, real estate transactions involve multi-million dollar amounts, making the industry an ideal target for BEC attacks.

Developers, property managers, and facility management companies process tenant personal data, lease agreements, financial data, and access control systems — leaking this data has serious legal and business consequences.

Sector-specific challenges

Smart buildings and IoT attack surface

An average smart building has 40,000 vulnerable IoT points: temperature sensors, HVAC controllers, surveillance cameras, access control readers, intelligent elevators. Most of these devices run firmware without security updates and communicate over unencrypted protocols (BACnet, Modbus). Compromising the BMS allows an attacker to manipulate climate control, lighting, and even physical access to the building.

BEC in real estate transactions

Business Email Compromise attacks target transaction culmination points — impersonating notaries, developers, or property managers to request transfers to modified account numbers. In real estate, where individual transactions reach millions, BEC losses are particularly severe.

Distributed building management

A company managing a property portfolio must secure dozens of buildings with separate BMS systems, networks, and vendors. Lack of centralized security management means each building represents a separate risk.

How nFlo helps the real estate industry

• Security audits — BMS, IoT, and building infrastructure security assessment
• Training — BEC awareness programs for transaction teams and property managers
• SOC as a Service — monitoring covering both IT systems and building IoT

Key first steps

1. IoT inventory — map all devices connected to the building network
2. BMS network segmentation — separate building automation systems from corporate and tenant networks
3. Transfer verification procedures — multi-level confirmation for transactions above a defined threshold
4. Firmware updates — regular patching of IoT devices and BMS controllers
