The New Reality of Connected Devices
Connected devices are now everywhere. Smart home products, industrial sensors, medical devices, wearables, routers, gateways, security cameras, Bluetooth accessories and LTE-connected systems all rely on wireless communication. These products make life easier and business operations more efficient, but they also create new cybersecurity risks.
This is why IoT cybersecurity compliance has become a major concern for manufacturers. It is no longer enough for an IoT device to work well, connect quickly and offer useful features. The device must also protect users, networks and data from cyber threats.
At the same time, manufacturers that sell wireless products in Europe must also understand RED compliance. RED stands for the Radio Equipment Directive, the European regulatory framework for radio equipment. For many connected wireless devices, RED compliance now includes cybersecurity requirements, especially for products that connect to the internet, process personal data or support financial transactions. The cybersecurity requirements under RED became mandatory from August 1, 2025 for relevant radio equipment placed on the EU market.
What Is IoT Cybersecurity Compliance?
IoT cybersecurity compliance refers to the process of making sure that connected devices meet recognized cybersecurity requirements, standards and best practices. It focuses on protecting devices from unauthorized access, data theft, network attacks, firmware manipulation and privacy risks.
An IoT device may collect personal information, location data, health data, payment information or operational data from a business environment. If this data is not protected, the consequences can be serious. A vulnerable smart camera may expose private spaces. A weak industrial sensor may create a path into a factory network. A poorly secured medical device may raise both safety and privacy concerns.
IoT cybersecurity compliance usually includes secure authentication, encrypted communication, secure software updates, vulnerability management, access control, privacy protection and protection against device misuse. It also requires manufacturers to think about security throughout the full product lifecycle, from design and development to testing, market release and post-market support.
What Is RED Compliance?
RED compliance refers to compliance with the European Union’s Radio Equipment Directive. This directive applies to radio equipment placed on the EU market, including products that use Wi-Fi, Bluetooth, LTE, 5G, Zigbee, NFC and other wireless technologies.
Traditionally, RED compliance focused on areas such as health and safety, electromagnetic compatibility and efficient use of the radio spectrum. However, as wireless products became more connected, cybersecurity became a much more important part of the regulatory picture.
The RED cybersecurity requirements are connected to Articles 3(3)(d), 3(3)(e) and 3(3)(f). These areas focus on protecting networks, protecting personal data and privacy, and reducing the risk of fraud.
For manufacturers, this means that RED compliance is not only about radio performance. It is also about proving that the connected wireless product includes appropriate cybersecurity protections.
The Connection Between IoT Cybersecurity Compliance and RED Compliance
The connection between IoT cybersecurity compliance and RED compliance is especially important for wireless IoT products. If a device is connected to the internet and uses radio communication, it may fall under both cybersecurity expectations and RED regulatory requirements.
For example, a smart thermostat, wireless security camera, Bluetooth medical sensor, LTE gateway, connected payment device or industrial IoT controller may need to meet IoT cybersecurity compliance expectations and also demonstrate RED compliance for access to the European market.
In simple terms, IoT cybersecurity compliance is the broader concept. It can apply to connected products in many markets and industries. RED compliance is more specific. It applies to radio equipment in the European regulatory framework. When an IoT product includes wireless communication and is sold in Europe, these two areas become closely connected.
This is why manufacturers should not treat cybersecurity as a separate technical issue. It should be part of the compliance strategy from the beginning.
Why Wireless IoT Devices Are High-Risk Products
Wireless IoT devices are attractive targets for cyberattacks because they communicate through radio signals and often connect to larger networks. Unlike a purely wired product, a wireless device can sometimes be targeted remotely or from nearby radio range.
Many IoT products are also built with limited hardware resources. They may have small processors, limited memory and low power consumption requirements. These limitations can make it more difficult to implement strong security controls. In some cases, manufacturers may release products with weak default passwords, insecure firmware updates, poor encryption or insufficient access control.
The risk grows when one weak device becomes a gateway into a larger system. A vulnerable wireless sensor may allow attackers to move into a business network. A compromised smart home product may expose private user data. A poorly secured payment-related device may increase the risk of fraud.
This is exactly why IoT cybersecurity compliance and RED compliance are becoming more important. They help manufacturers reduce these risks before products reach the market.
EN 18031 and Cybersecurity Requirements for Radio Equipment
The EN 18031 series is highly relevant for manufacturers preparing for RED cybersecurity requirements. EN 18031-1 focuses on common security requirements for internet-connected radio equipment. EN 18031-2 focuses on radio equipment that processes personal data, traffic data or location data. EN 18031-3 focuses on radio equipment that processes virtual money or monetary value.
These standards help manufacturers understand how to approach cybersecurity testing and documentation for RED compliance. They also give structure to the broader process of IoT cybersecurity compliance.
For a manufacturer, this can include reviewing the product’s communication interfaces, identifying sensitive assets, checking authentication mechanisms, verifying update security, protecting stored and transmitted data, and documenting how the product reduces cybersecurity risks.
What Manufacturers Should Do
Manufacturers should start with a cybersecurity risk assessment. They need to understand what the device does, what data it processes, how it connects to other systems and what could happen if the device is compromised.
Security should then be built into the product design. This includes strong authentication, secure pairing, encrypted communication, protected firmware updates, secure key management and clear access control. Devices should not rely on weak default credentials or unsafe communication methods.
Manufacturers should also create technical documentation that explains how the product meets relevant cybersecurity requirements. For RED compliance, documentation and testing can be critical for market access. For IoT cybersecurity compliance, documentation also supports trust with customers, partners and regulators.
Testing should happen before the product is released. Cybersecurity testing can reveal weaknesses that may not appear during normal functional testing. It can also help manufacturers avoid costly redesigns, compliance delays or reputational damage.
Why Early Compliance Planning Matters
Waiting until the final stage of development can create serious problems. If cybersecurity is added only at the end, the manufacturer may discover that the product architecture does not support secure updates, proper encryption or strong user authentication.
Early planning makes the process easier and more cost-effective. It allows the development team to choose the right components, design secure software, prepare documentation and test the product against relevant requirements.
For companies targeting the European market, early planning is especially important because RED compliance can affect CE marking and market access. For global manufacturers, IoT cybersecurity compliance can also support broader regulatory readiness as cybersecurity rules continue to expand in different regions.
Conclusion
IoT cybersecurity compliance and RED compliance are closely connected when it comes to connected wireless devices. IoT cybersecurity compliance focuses on protecting connected products, users, networks and data. RED compliance focuses on meeting European regulatory requirements for radio equipment, including cybersecurity obligations for many wireless products.
For manufacturers of Wi-Fi, Bluetooth, LTE, 5G and IoT devices, these two areas should be part of one clear strategy. A secure product is not only better protected against cyber threats. It is also better prepared for certification, market access and long-term customer trust.
As wireless devices become more common and more powerful, cybersecurity can no longer be treated as an optional feature. It must be built into the product, tested properly and documented clearly. For modern connected devices, strong cybersecurity is now part of responsible design, regulatory compliance and successful market entry.
