The world of business is rapidly changing with the rise of the Internet of Things (IoT). More companies are using IoT devices to improve operations, enhance customer experiences, and innovate in their fields. However, as businesses adopt these connected devices, they also face new security risks.
Ensuring that these devices and the network they operate on are secure is crucial. Events like WIoT Tomorrow, which focus solely on products, solutions, and trusted partners in the IoT universe through an expo, summit, and special arenas, provide an excellent opportunity to connect with reliable and secure providers of IoT products and solutions, as well as to stay updated on the latest industry developments.
The Growing Threat of Cyber Attacks in IoT
IoT devices, like smart sensors, connected machines, and other networked devices, offer many benefits, including increased efficiency, cost savings, enhanced data insights, improved decision-making, and the ability to create innovative business models that can be true game changers in the industry. But they also increase what’s known as the attack surface. This term refers to the different points where an unauthorized user could try to gain access to your network. The more devices connecting to your network, the larger this surface becomes, and the higher the risk of security issues.
Cybercriminals are always looking for ways to exploit these vulnerabilities. If they manage to gain access to even one vulnerable device, it could lead to a data breach that affects your entire business. This could result in stolen data, disrupted operations, and significant financial losses. For companies, especially those in B2B, these security issues can also damage relationships with clients and partners.
EU’s New Cybersecurity Guidelines for IoT Devices
To address these growing concerns, the European Union (EU) is introducing new cybersecurity guidelines that will impact all businesses using IoT devices. Starting in August 2025, the Radio Equipment Directive (RED) will require that all IoT devices meet specific cybersecurity standards before they can be sold in the EU. This new rule is important for businesses because it ensures that devices are secure before they are put to use, reducing the risk of security breaches.
For B2B companies, this means that the security posture of all IoT devices needs to be strong enough to comply with these new standards. According to cybersecurity expert Olaf Wilmsmeier, “Device manufacturers should not underestimate the time required for this process. Starting today will help avoid last-minute challenges when the regulations take effect.”
The EU’s cybersecurity guidelines focus on making sure that IoT devices have secure operating systems, do not use default passwords, and include other built-in security solutions to protect against IoT security threats. This means that businesses need to pay close attention to the security of both their devices and the network they connect to.

How to Secure Your IoT Ecosystem
For businesses using IoT technology, following these guidelines is not just about meeting legal requirements—it’s about protecting your operations and keeping your data safe. Here are some steps you can take to improve the security of your IoT ecosystem:
- Conduct Comprehensive Risk Assessments: Before deploying any new IoT devices, it’s important to understand the security risks involved. By performing a thorough risk assessment, your security teams can identify potential vulnerabilities in your system. This process helps you pinpoint where your attack surface is largest and where you need to implement stronger security measures.
- Implement Robust Security Protocols: Ensure that all your IoT devices use strong encryption, secure authentication methods, and are regularly updated. Encryption helps protect data as it moves between connected devices and the central system. Secure authentication prevents unauthorized users from accessing your network by requiring users to verify their identity before gaining access. Regular updates ensure that any newly discovered vulnerabilities in the operating systems are patched, keeping the devices secure.
- Segment Your Networks: To reduce the impact of a potential breach, consider separating your IoT devices into different network segments. This way, if one device is compromised, the attacker won’t automatically gain access to your entire system. For example, you could separate devices used for internal operations from those that connect directly to the internet.
- Work with Trusted Manufacturers: When purchasing IoT devices, it’s essential to choose manufacturers that comply with the latest cybersecurity standards. These manufacturers should offer secure devices with built-in protections and provide ongoing support for updates and patches. Vulnerable devices from unreliable sources could put your entire network at risk. Going to events like WIoT Tomorrow, which assemble the who’s who of IoT solution and product providers, offers a prime opportunity to find trusted and reliable partners who adhere to the highest security standards.
- Prepare for EU Compliance: If your business operates in the EU or plans to enter that market, you need to start preparing now for the new RED requirements. As Wilmsmeier highlights, the time to act is now, as waiting too long could lead to non-compliance, which means your products can no longer be sold in the EU.
- Educate Your Employees on IoT Security: Your employees play a critical role in maintaining the security of your IoT ecosystem. Make sure they understand the importance of IoT security and are trained to recognize potential threats. Simple actions, like not using default passwords or being aware of phishing attempts, can make a big difference in protecting your data.
Addressing Common IoT Security Issues
As you strengthen your IoT security, it’s important to be aware of some common issues that can arise:
- Default Passwords: Many IoT devices come with default passwords that are easy for attackers to guess. Always change these passwords to something unique and difficult to guess as soon as you set up a new device.
- Unpatched Devices: IoT devices often require software updates to fix security vulnerabilities. Make sure that all devices connecting to your network are regularly updated to the latest versions of their operating systems.
- Weak Encryption: Ensure that any data transmitted between your IoT devices and central systems is encrypted. This makes it much harder for attackers to intercept and read your data.
The Future of IoT Security
As businesses continue to embrace IoT technology, the need for robust security will only grow. The IoT security threats we face today are likely to evolve, becoming more sophisticated and harder to detect. By taking proactive steps to secure your IoT devices and networks now, you can protect your company’s data and ensure that your business remains resilient in the face of new challenges.
The upcoming EU guidelines are a wake-up call for many businesses. They highlight the importance of securing IoT devices and the need for a comprehensive approach to cybersecurity. For B2B companies, this means not only complying with new regulations but also adopting a mindset that prioritizes security in all aspects of your operations.
By focusing on securing your IoT ecosystem, you can protect your business from the growing threats of cyberattacks, maintain customer trust, and ensure that your operations run smoothly in an increasingly connected world. Events like WIoT Tomorrow are invaluable for staying informed, connecting with trusted partners, and finding secure solutions tailored to your needs. As the deadline for EU compliance approaches, businesses that act now to enhance their IoT security will be better positioned to thrive in the future.
