CYBER GREEN CONSULTING LTD

What CYBER GREEN CONSULTING LTD does

Cyber Green Consulting Ltd is a UK-based professional services firm founded in 2025 that specialises in auditing and securing the IoT and OT systems embedded in smart commercial buildings. Its work covers building management systems, HVAC controllers, access control, IoT sensors, energy metering, and AV equipment, producing verified asset inventories and vulnerability risk assessments aligned with ISO 27001, SOC 2, NIS2, and NCSC CAF requirements. The firm's differentiator is its integrated Cyber-ESG methodology, the four-stage Assess → Secure → Optimise → Sustain framework, which positions cyber remediation as a route to measurable energy savings, arguing that disabled or unoptimised building automation typically makes the security investment cost-neutral or better.

The company is led by a founding team that previously managed a global technology company's digital building cyber security programme across more than 500 sites worldwide over four years, conducting hundreds of IoT/OT building surveys in that period. Service delivery is bespoke, quote-based, and enterprise-focused, targeting CISO, Head of Sustainability, and CFO stakeholders simultaneously to align cyber security, ESG reporting, and financial ROI in a single engagement. Distribution is entirely direct, via website consultation requests and enterprise field sales, with no channel partners, resellers, or marketplace presence.

Revenue mechanics are project-based professional services with no publicly disclosed pricing or contract values. Operating geography is the United Kingdom, with the registered office in Thames Ditton, Surrey. The company is privately held and bootstrapped, with no institutional funding, parent, or subsidiary relationships disclosed. The only public customer case study references a Fortune 500 London headquarters audit that identified 115 critical vulnerabilities and identified up to 50% energy cost savings with a six-figure annual saving potential.
