Property & Real Estate Cyber Security
Your buildings are getting smarter. Your attack surface is growing with them. BMS controllers, IoT sensors, tenant portals, and high-value transaction systems create entry points that traditional IT security does not cover. Our CREST-accredited consultants assess the full property technology estate: smart building IoT, PropTech platforms, multi-tenant network segmentation, and transaction fraud controls.
Full-Stack Property Security:
Buildings to Boardrooms
Property cyber security spans IoT building systems, PropTech platforms, multi-tenant networks, and high-value transaction controls. We assess the full technology estate in a single engagement.
Smart Building & IoT Assessment
Security assessment of BMS, HVAC controllers, access control systems, CCTV, elevator controls, lighting automation, and IoT sensors. We identify lateral movement paths from building systems to corporate networks and tenant environments.
PropTech Platform Testing
Tenant portals, property listing platforms, online viewing and booking systems, virtual staging tools, and property management SaaS applications tested for OWASP Top 10 and business logic vulnerabilities that automated scanners miss.
Multi-Tenant Network Isolation
Validation of network segmentation in shared environments: co-working spaces, managed offices, and multi-tenant buildings. We verify that one tenant cannot access another tenant's traffic, systems, or data through shared VLAN and infrastructure configurations.
BEC & Fund Diversion Prevention
High-value property transactions are targeted by BEC and fund diversion attacks. We test email security controls, domain spoofing resistance, invoice verification procedures, and communication channel integrity between estate agents, solicitors, and buyers.
Tenant PII & GDPR Exposure
Property management companies hold extensive PII: identity documents, financial records, right-to-rent evidence, and DBS outcomes. We assess data handling, access controls, and encryption to validate GDPR Article 32 compliance.
Physical-Digital Convergence
Modern property relies on converging physical and digital systems. We test the boundary between IT networks and OT building systems, validating that a compromise in one domain cannot cascade into the other.
Property Sector Risk Profile
Smart buildings and PropTech platforms are expanding the property sector attack surface. 45% of smart buildings have at least one exploitable vulnerability in building management systems.
Avg. Property Breach

When Do Property Companies Commission Security Testing?
Property sector security engagements are typically triggered by one of these six scenarios. If any of these apply, you are in the right place.
Smart Building Deployment
A new smart building or BMS upgrade is approaching commissioning and you need to validate that IoT, HVAC, and access control systems are isolated from tenant and corporate networks.
Transaction Fraud Incident
A BEC attack or funds diversion attempt has targeted your property transactions. You need to assess email security, domain impersonation controls, and invoice verification procedures.
Investor Due Diligence
Institutional investors, fund managers, or REIT governance requirements demand evidence of independent penetration testing and Cyber Essentials Plus certification.
PropTech Platform Launch
A new tenant portal, property listing platform, or property management SaaS application is approaching go-live and requires security sign-off.
Multi-Tenant Segmentation Concern
You manage co-working spaces, managed offices, or multi-tenant buildings and need to validate that network segmentation prevents cross-tenant access.
Cyber Insurance Renewal
Your insurer requires evidence of penetration testing, smart building security assessment, or Cyber Essentials as a condition of policy renewal or favourable premium.

Frequently Asked Questions
Common questions about this service, methodologies, and deliverables.
Yes. Our IoT and OT security consultants assess building management systems (BMS), HVAC controllers, access control systems, elevator controls, lighting automation, and CCTV networks. We identify paths from building systems to corporate networks and tenant environments.
Transaction fraud: particularly BEC targeting high-value property purchases and commercial deals. Attackers intercept communications between estate agents, solicitors, and buyers to redirect deposits and completion funds.
Yes. We test tenant portals, property listing platforms, online viewing and booking systems, virtual staging tools, and property management SaaS applications for OWASP Top 10 and business logic vulnerabilities.
We assess network segmentation in shared environments (co-working spaces, managed offices, and multi-tenant buildings) to verify that one tenant cannot access another tenant's traffic, systems, or data through shared infrastructure.
Yes. Cyber Essentials is increasingly expected by institutional investors during due diligence, by commercial tenants in managed buildings, and by professional indemnity and cyber liability insurers. It provides a cost-effective baseline of technical assurance.
Penetration testing for property companies starts from £3,750 for web application and network assessments. IoT and smart building security assessments typically range from £8,000 to £20,000 depending on building complexity and number of BMS, HVAC, and access control systems. Cyber Essentials Plus certification starts from £2,500. 24/7 SOC monitoring for property infrastructure starts from £3,500/month. We provide fixed-price quotes after understanding your property portfolio and technology estate.
