OT Cybersecurity Risk Assessment for Smart Buildings

Smart buildings bring efficiency but also new cyber risks. We help organisations protect these critical systems, reduce risk, and align operational technology with broader cybersecurity strategies.

The challenge

Security blind spots

Modern smart building systems often operate outside traditional IT oversight, leaving critical infrastructure vulnerable. While these systems deliver efficiency and cost savings, their procurement and management frequently fall to facilities or operations teams, not cybersecurity.

Interconnected systems, unseen risks

The integration of smart technologies creates complex networks with new vulnerabilities. These systems are often controlled remotely or by third parties, introducing additional entry points for cyber threats.

Efficiency first, security second

The focus on convenience, energy efficiency, and operational performance has meant cybersecurity is rarely prioritised during procurement or deployment. As a result, many smart building environments remain exposed, with legacy systems, outdated software, or default credentials still in use.

The service

BH Consulting can help in different ways, however we tend to start most engagements with a standards based ‘Smart Building Cybersecurity Risk Assessment’ in line with ISA/IEC 62443 and ISO 27001.

The aim of this assessment is to provide an objective review of current smart building cybersecurity posture, measured against internationally recognised standards and best practice.

The output of this assessment will be a report of findings and recommendations that will leave your organisation with an improved understanding of what threats and risks exist in the management of systems that control your Smart Building, and how to remedy them.

The Assessment will cover a wide range of security areas and functions such as:

  • System security requirements and security levels
  • Security technologies in use for industrial automation and control systems
  • Secure product development lifecycle
  • User access and authorisation management
  • Cloud security
