How Secure Is Energy Monitoring Technology? Inside Clearworld’s Approach to Network Security

Energy monitoring technology can help businesses identify energy waste, improve building performance and reduce operating costs. But before connecting any new technology to your buildings, there’s another important question to ask: how secure is the network behind it?

It might not be the most exciting part of energy management, but network security matters. Businesses need to understand how their energy data travels, how their systems are connected and what measures are in place to protect their infrastructure.

At Clearworld, we take network security seriously. Our energy monitoring systems use security features built into the LoRaWAN communication protocol, encrypt data as it travels to the relevant dashboard and cloud, and provision control systems on isolated network segments secured with strong passwords.

So, while we’re busy helping businesses understand their energy usage, we’re also paying attention to the technology that makes those insights possible.

Because lower energy bills are brilliant. Knowing your systems are designed with security in mind is pretty important, too.

Why Is Network Security Important in Energy Monitoring?

Modern buildings rely on connected technology to collect information about energy consumption, equipment performance and building conditions. Energy monitoring systems use sensors to gather data and make it available through dashboards, helping businesses understand how their buildings operate.

For organisations managing commercial buildings, offices, retail premises, restaurants or multiple sites, this information can be valuable. It can help identify unusual consumption, highlight opportunities to reduce waste and support better energy management decisions.

However, connected devices also introduce important considerations around network security.

Businesses need to understand how devices communicate, how data is transmitted and how the different parts of an energy monitoring system are protected.

This is particularly relevant when introducing new technology into an existing business environment, where IT teams may need to understand how it fits alongside other systems.

The good news? Security doesn't have to be an afterthought. By considering how the network is designed, how data is protected and how access is controlled, businesses can make more informed decisions about the technology they introduce.

LoRaWAN Security: Protecting Wireless Sensor Communications

Clearworld uses LoRaWAN, a wireless communication protocol designed for low-power, long-range Internet of Things (IoT) devices.

In simple terms, LoRaWAN allows compatible sensors to transmit information wirelessly without requiring the same power consumption as many other wireless technologies. This makes it useful for applications such as building monitoring, where sensors may need to operate for extended periods.

But what about security?

Security is built into the LoRaWAN protocol itself. Its security mechanisms include encryption designed to protect data transmitted between devices and the network infrastructure.

This helps prevent someone who intercepts the encrypted wireless messages from simply reading the underlying sensor data.

For energy monitoring, that matters because information collected by sensors needs to travel from the point of measurement to the systems that process and display it.

Rather than relying solely on the physical security of the devices or the location in which they're installed, LoRaWAN incorporates security mechanisms into the way communications work.

Why does this matter for businesses?

It means wireless sensor communications benefit from security features built into the communication protocol, helping protect the data being transmitted.

Of course, overall security also depends on correct configuration, key management and the wider system design. But having security built into the protocol is an important part of the picture.

Encrypted Data Transmission: From Sensors to Your Dashboard

Collecting energy data is only part of the process. That information also needs to reach the systems where businesses can use it.

Clearworld encrypts data in transit as it travels to the relevant dashboard, such as Vision iQ. Data sent to the cloud is also encrypted.

But what does encryption in transit actually mean?

Encryption transforms readable information into an encoded form while it is being transmitted. Without the appropriate cryptographic keys and mechanisms, an unauthorised party who intercepts the encrypted data cannot simply read it as ordinary information.

This is particularly important when data moves between different parts of a connected system.

For example, energy monitoring data may travel through several stages before it appears in a dashboard. Encrypting data in transit helps protect it as it moves through that process.

Why is encrypted data important for energy monitoring?

Encryption helps reduce the risk of sensitive information being exposed while it travels between systems.

It is an important security measure for connected technology, particularly when businesses rely on cloud-based platforms to access their energy information.

For businesses using Clearworld's energy monitoring solutions, encryption in transit forms part of the approach to protecting data as it moves through the system.

It is worth distinguishing this from encryption at rest, which protects stored data. The security measures described here relate specifically to data in transit.

Isolated Network Segments: Keeping Control Systems Separate

Another important part of network security is understanding how systems are connected to one another.

Clearworld provisions its control systems on isolated network segments, secured with strong passwords.

Network segmentation involves dividing a network into separate sections rather than allowing every device and system to communicate freely across the entire environment.

Think of it as having different areas for different purposes, with boundaries between them.

This can help limit unnecessary connectivity and reduce the extent to which an issue affecting one part of a network could impact other connected systems.

For example, where network segmentation is appropriately configured, a device or system on one segment may not have unrestricted access to systems on another.

The exact protection depends on how the segmentation and access rules are implemented, but the principle is straightforward: systems should only have the connectivity they need.

Why does network isolation matter?

Separating control systems into isolated network segments is an important way to structure a connected environment.

Combined with appropriate access controls, segmentation helps establish boundaries around systems that need to be managed and protected.

For businesses, this provides a clearer approach to organising network connectivity, rather than treating every connected device as part of one unrestricted network.

And, as with any security measure, the details matter. Network isolation works alongside other safeguards rather than replacing them.

Strong Passwords and Controlled Access

Even well-designed network infrastructure needs appropriate access protection.

Clearworld secures its isolated control system network segments with strong passwords, helping prevent unauthorised access.

Passwords are a fundamental part of access security. They help ensure that access to systems is restricted to people who have the necessary credentials.

Weak or reused passwords can create avoidable security risks. Strong passwords make unauthorised access more difficult, particularly when combined with other appropriate security measures.

For connected energy monitoring systems, access security matters because dashboards and control systems provide the interfaces through which users interact with the technology.

Businesses should consider who needs access to their systems, how credentials are managed and whether access arrangements remain appropriate over time.

Strong passwords are one part of that wider picture. They work alongside network segmentation, secure communications and the other safeguards implemented within a system.

Bringing These Security Measures Together

Network security is rarely about one individual feature. It is about how different measures work together.

Clearworld's approach incorporates several important elements:

• LoRaWAN security: Security mechanisms built into the wireless communication protocol help protect sensor communications.

• Encryption in transit: Data is encrypted as it travels to the relevant dashboard, including Vision iQ.

• Encrypted cloud transmission: Data sent to the cloud is encrypted in transit.

• Network segmentation: Control systems are provisioned on isolated network segments.

• Password protection: Strong passwords help protect access to control system environments.

Each measure addresses a different part of the system.

The communication protocol provides security mechanisms for wireless sensor communications. Encryption helps protect information while it travels between systems. Network segmentation establishes boundaries between parts of the infrastructure, while strong passwords help restrict access.

Together, these measures form part of the security approach supporting Clearworld's energy monitoring technology.

No single measure guarantees complete security, and the effectiveness of any system depends on its implementation and ongoing management. However, understanding how these protections fit together helps businesses make better-informed decisions about the technology they use.

Energy Management and Security Should Go Hand in Hand

Businesses invest in energy monitoring because they want better visibility of their buildings and greater control over their energy consumption.

The potential benefits can be significant. Clearworld helps businesses identify opportunities to reduce energy waste, understand consumption patterns and make more informed decisions about building performance.

But the technology delivering those insights also needs to be considered carefully.

For IT teams, that means understanding how devices communicate, how data is transmitted and how connected systems are structured.

For facilities and energy managers, it means looking beyond the dashboard to understand the infrastructure supporting the information they rely on.

And for business leaders, it means considering energy performance and technology security as part of the same conversation.

At Clearworld, we believe both deserve attention.

Because improving energy efficiency is important. Protecting the systems that support that improvement matters, too.

And if better visibility helps you find opportunities to reduce your energy bills along the way? Well, that's certainly nothing to sniff at.

Smarter Energy. Security Taken Seriously.

Energy monitoring should give businesses greater visibility of their buildings and help them make informed decisions about energy use.

At Clearworld, we combine energy monitoring technology with a considered approach to network security, incorporating protected wireless communications, encrypted data transmission, isolated control system network segments and strong passwords.

Because better energy management is about more than knowing where your energy goes. It's about having confidence in the technology helping you understand it.
