Old-School Cybersecurity is Putting Real Estate at Risk

What worked yesterday in real estate cybersecurity is often today’s biggest liability. Too many multi-family and office property firms still depend on firewalls, static passwords, and annual compliance checklists. Attackers know these are the easiest ways in—and they’re exploiting them every day.

What worked yesterday in real estate cybersecurity is often today’s biggest liability. Too many multi-family and office property firms still depend on firewalls, static passwords, and annual compliance checklists. Attackers know these are the easiest ways in—and they’re exploiting them every day.

The Reality Has Shifted

The way properties operate has changed dramatically in the past decade. Consider these trends:

  • Distributed Workforces: Leasing teams, property managers, and vendors now connect from anywhere, often using personal devices and unsecured networks.
  • Complex Tech Ecosystems: Building systems and apps span cloud platforms, SaaS tools, and APIs, creating multiple entry points for attackers.
  • Sophisticated Threat Actors: Cybercriminals use organized, automated tools that make exploitation fast, cheap, and scalable.

Despite these changes, many firms still cling to outdated practices:

  • Relying on VPN-only access as the sole security measure.
  • Skipping multi-factor authentication (MFA) on critical systems.
  • Running periodic vulnerability scans instead of continuous monitoring.

These gaps are exactly what attackers look for. A single weak link can compromise an entire portfolio.

Why It Matters

A breach isn’t just an IT problem—it’s a business crisis. The consequences can include:

  • Exposure of tenant data, leading to legal and compliance headaches.
  • Disruption of building operations, from HVAC failures to locked-out access control systems.
  • Costly downtime and reputational damage, which can erode tenant trust and impact leasing.

For property owners and operators, cybersecurity is now an operational and reputational risk. Tenants expect their personal data and building systems to be as secure as the locks on the front door. Falling short can mean losing business.

What Leaders Should Prioritize Now

To stay ahead of evolving threats, real estate firms need a proactive, layered approach. Here’s where to start:

  • Property-Level Cybersecurity Assessments: Evaluate existing assets and include cybersecurity in acquisition due diligence.
  • NIST-Based Maturity Reviews: Benchmark your readiness against industry standards to identify gaps.
  • 24/7 SOC Monitoring: Detect and respond to threats in real time, not weeks after an incident.
  • OT Network Security: Protect operational technology like HVAC, elevators, and access control systems from cyber compromise.
  • Regular Staff Training: Human error remains a top cause of breaches—empower your team to recognize and avoid risks.

Bottom Line

If your cybersecurity strategy hasn’t been updated in the last five years, you’re not just behind—you’re a target. The threat landscape is evolving faster than ever, and attackers know where the weak spots are. Modernizing your approach isn’t optional; it’s essential for protecting your tenants, your assets, and your reputation.
