Securing OT & IoT in Building Management Systems

Why is Improving Cybersecurity So Critical for Today’s Smart Buildings?

Faced with increasing cybersecurity insurance premiums and liability risks, plus rising energy costs, building owners are under pressure to improve both security and operating efficiencies. Challenges include:


  • Increasing, targeted cyberattacks on building systems
  • Expanded cyberattack surface due to digital transformation
  • Poor visibility into IoT and OT devices and networks
  • Lack of resources to detect and mitigate security threats
  • Ensuring occupants are safe, productive and comfortable
  • Incorporating new technology to reduce costs without increasing cyber risk

To reduce liabilities and reputational risk, building owners need to ensure that IoT/OT visibility and security is improved.

The impact of cyber incidents can go beyond financial loss; operational and reputational damage can be equally critical, if not more so.
As more building owners understand the potential effect of an OT attack on operations and infrastructure, facility managers will be in a better position to make smart buying decisions and heighten cyber resilience across OT environments.

You Can't Protect What You Can't See

Good security starts with great visibility. Nozomi Networks leads the industry in IoT/OT visibility and situational awareness.

The first step in improving the cybersecurity posture of your buildings is being able to see all the devices and networks in your buildings. The Nozomi Networks solution automates asset inventory, no matter the vendor, and allows you to see your entire IoT and building automation ecosystem in one place. This includes your building’s access control, CCTV, elevator, energy management, fire, HVAC, IoT, lighting systems and more. It saves you time and money by providing always up-to-date, accurate system information—the foundation for zero trust security. In addition, Nozomi Networks improves your situational awareness with a live, interactive network visualization. This shows assets, links, traffic, data flows and morequickly becoming an indispensable monitoring tool. Companies with dispersed properties benefit from a consolidated, single pane of glass view of systems for all buildings. Visibility drives confidence. A clear view of your IoT devices and building management systems is fundamental to improving cyber risk management across your building systems and properties.

Keeping occupants comfortable, safe, and free to come and go is fundamental to building management. Yet, today’s intelligent building systems are vulnerable to cyber threats and downtime risks.

A building’s complex and diverse systems provide a large attack surface for threat actors. Cyber threats continue to escalate, with the potential to impact more than just IT networks. Core building systems could be compromised, and in the worst case, come to a standstill or be taken offline to protect them.

A key requirement for securing buildings is detecting threats. The Nozomi Networks platform detects malware and IOCs by combining multiple types of OT/IoT/IT threat detection and by receiving continuously updated threat and asset intelligence. It helps you respond efficiently to IT/OT incidents with correlated alerts and actionable intelligence that leads to swift remediation.

Our solution rapidly and passively detects vulnerabilities across a wide range of devices, networks and vendors. Its dashboards and reports help you efficiently prioritize and address risks.

Nozomi Networks helps you prevent or minimize security breaches and ransomware attacks. It also helps you achieve cybersecurity best practices, limiting your liability risk and improving your risk management.

Expand Your Cybersecurity Strategy

Building networks may be monitored by IT cybersecurity tools and programs today, but if existing and newly added IoT and OT devices are not adequately covered, they are exposed to cyber risk.

To limit cyber risk and financial liability, building operators need a comprehensive cybersecurity strategy that covers not just traditional IT systems, but expanding IoT and building management systems infrastructure.

The right IoT/OT solution helps future-proof your buildings with continuous threat intelligence to counter tomorrow’s malware and scalability to handle new technology and properties.

Scale Up

Dispersed buildings, quickly evolving IoT systems and changing building portfolios require monitoring at scale. It’s critical to implement a solution that can protect any number of OT, IoT, IT, edge and cloud assets.

You need an easy-to-deploy and resource-efficient system that scales elegantly. A SaaS-powered application provides a single pane of glass view of aggregated and prioritized risks across all facilities. It scales quickly and reduces complexity and cost. Paired with a wide range of on-site sensors, such a system meets the needs of any type of property.

The Nozomi Networks solution scales smoothly and is easily tailored to meet your needs. It allows you to monitor very high numbers of building assets and locations in a cost- and resource-efficient way.
