Your Smart Building Is Connected.
But Is It Secure?
In 2025 alone, cyber attacks cost UK businesses billions.
Most smart buildings contain over 100 cyber vulnerabilities. Many building operators have no idea what's connected to their network or what it's costing them in risk, energy waste, and regulatory exposure.
2025: Cyber Attacks Cost UK Businesses Billions
A UK manufacturer lost £1.9 billion. A UK retailer lost £300 million. A UK convenience chain lost £80 million. All in the same year.
Your building systems - BMS, HVAC, access control, IoT devices - are the next target. Most have never been properly audited or secured.
Do you know what's on your network?
The Cost of Doing Nothing
A cyber attack on your building management system isn't just an IT problem. It can mean:
- Complete loss of HVAC, access control, lighting and security systems
- Average cost of a cyber breach: £3.4 million
- Regulatory fines under NIS2 of up to £17 million or 4% of global turnover
- Insurance claims rejected due to unpatched or undocumented vulnerabilities
- Reputational damage that outlasts the incident itself
The threat is real. The good news - it's measurable, manageable, and often self-funding.
Cyber Risk Management
Unmanaged IoT and OT devices are the fastest growing attack vector in commercial real estate. Building management systems, HVAC controllers, access control, metering, and AV equipment are all potential entry points and most building operators have no complete picture of what is actually connected to their network.
Our comprehensive IoT/OT building audits deliver a verified asset inventory and risk assessment the foundational layer required by ISO 27001, SOC 2, NIS2, and NCSC CAF.
We don't just find the risks. We tell you exactly what to do about them.
Energy Efficiency Optimisation
Security concerns are silently disabling building automation systems in commercial properties across the UK and nobody notices until the energy bill arrives.
When building automation is switched off due to unresolved cyber risks, HVAC, lighting and environmental controls run unscheduled and unoptimised 24 hours a day, 7 days a week. The energy waste is substantial. In our experience, it is also entirely preventable.
Our integrated approach identifies how cyber vulnerabilities are directly blocking operational efficiency and remediation typically unlocks energy savings that make the security investment cost-neutral or better.
Regulatory Compliance Assurance
The regulatory landscape for building cyber security is tightening fast.
NIS2 is now in force across the EU and influencing UK policy, with fines of up to £17 million or 4% of global annual turnover for non-compliance. Cyber insurers are increasingly requiring demonstrated security controls and rejecting claims where basic hygiene has not been maintained.
For organisations with ESG commitments, the stakes are higher still. Investors, tenants and regulators are demanding verifiable, auditable sustainability data and the building systems that generate that data must be secure to be trusted.
Cyber Green provides the asset inventory, risk documentation, and remediation roadmap that underpins compliance - turning regulatory pressure into a managed, evidenced process.
Security and Sustainability - Two Sides of the Same Challenge
Most organisations treat cyber security and sustainability as separate workstreams with separate budgets and separate teams. The result is that each one undermines the other.
Cyber Green was founded on a single insight: in smart buildings, you cannot achieve your sustainability goals without securing your building systems first. And when you do secure them, the energy and carbon savings are substantial.
Our integrated Cyber-ESG approach delivers measurable outcomes for your CISO, your Head of Sustainability, and your CFO in a single engagement.
