How the CRA Is Transforming Communication Network Infrastructure—What Your Business Needs to Do Now
Is your company's foundational network infrastructure truly equipped to fend off the ever-evolving threats of cybersecurity? Many organizations are still grappling with legacy systems that may expose them to vulnerabilities against today’s sophisticated cyberattacks. Once a security incident occurs, the repercussions can be devastating—business interruptions, leaks of confidential information, and significant damage to corporate value are all too real.
In response to this urgent issue, the European Cyber Resilience Act (CRA) entered into force in December 2024. This regulation requires companies providing digital products to adhere to stringent cybersecurity requirements throughout the entire product lifecycle, with the main obligations of the Act applying from December 2027. Failure to comply could result in hefty fines and, more critically, a de facto exclusion from the European market—consequences that could be catastrophic for any business. This is no longer just a technical challenge; it’s a vital strategic concern for leadership.
In this article, we introduce you to a revolutionary communication technology called "Nessum". Nessum addresses the cybersecurity challenges faced by companies with existing legacy systems at their core, enabling compliance with the European Cyber Resilience Act while also laying a robust foundation for future business expansion. We delve into the specific benefits of Nessum and explore its technical aspects in detail.
Nessum Is Redefining Network Standards—Next-Generation Communication Using Existing Cabling
Nessum is a cutting-edge communication technology that enables IP-based communications using existing legacy network infrastructure. Whether it’s twisted pair cables, coaxial cables, or power lines, Nessum can upgrade any type of wiring into a communication line, providing a topology-free solution that contributes to low-cost network construction. The technical specifications are standardized as the IEEE 1901.
Key features of Nessum include:
- Enables the use of existing wiring regardless of cable type or wiring topology (no new wiring)
- Transforms low-speed, non-IP legacy wired communication into high-speed IP networks
- Supports wide-coverage networks through a large number of device connections (up to 1,024 nodes) and multi-hop (up to 10 hops) technology
- High security communication with data encryption, tone map generation, and IEEE 802.1X support
Breaking Free from Legacy Systems While Meeting CRA Requirements—Why Nessum Is the Smart Choice
What Security Requirements Does the CRA Demand? Nessum’s Technical Compatibility Explained
Under the European Cyber Resilience Act, the following requirements are imposed on digital products, including IoT devices:
- Security from the design and development stages: Cybersecurity must be considered throughout the design, development, and manufacturing phases of the product, and products must be placed on the market without any known vulnerabilities.
- Vulnerability management and security updates: When vulnerabilities are discovered, they must be addressed promptly, and security updates must be reliably provided.
- Risk assessment and documentation: Cybersecurity risk assessments must be conducted continuously and documented accordingly.
- Transparency and information provision: Detailed information about the product’s security features, clear instructions for safe installation, configuration, and use, as well as methods for reporting vulnerabilities, must be provided.
- Incident response and reporting: Any exploited vulnerabilities or significant security incidents must be promptly reported to the relevant authorities.
For detailed information on each requirement, refer to the official document issued by the European Union.
From the perspective of communication networks, the key to meeting these requirements is to ensure that transmitted information is protected with high-level security, while also being able to promptly and reliably provide security updates when vulnerabilities are discovered. Nessum not only meets these requirements but also offers a solution that enables smooth compliance with legal regulations while keeping costs low.
Beyond the Limits of Legacy Communication—Nessum’s New Approach to IP Migration
In many industrial networks, field-level communication still relies heavily on legacy, non-IP protocols such as RS485 or proprietary systems developed by manufacturers. Since these networks were not designed with modern cybersecurity in mind, they pose significant vulnerabilities, potentially serving as entry points for cyber threats. Security isn’t the only reason to rethink your network. Remote monitoring, efficient firmware updates, and seamless integration with modern IT systems all demand one thing: IP-based connectivity.
According to a survey by HMS Networks, 71% of new nodes in industrial networks are connected using Ethernet, with Fieldbus at 22% and Wireless at 7%. So, when you hear “migrating to IP networks”, your first thought might be: Let’s rebuild everything with Ethernet.But here’s the catch—this approach comes with hidden costs and limitations. "High cost of new cabling", "Need for network HUBs every 100 meters" — these challenges are far from trivial. They can become roadblocks in cost-sensitive or space-constrained applications. To truly unlock the benefits of IP networking, you need smarter solutions—ones that overcome these challenges without compromising performance or budget.
Nessum offers a smart and efficient solution to overcome these challenges. Unlike traditional approaches that require costly wiring and cable specifications, Nessum enables high-speed IP communication using existing wiring—regardless of cable type and topology. This means you can dramatically reduce installation costs while accelerating your network’s transition to IP. With transmission speeds ranging from several Mbps to tens of Mbps over distances of several kilometers, Nessum supports up to 1,024 devices per Master and features multi-hop automatic relay technology, making it ideal for building large-scale industrial networks. Security is also a high priority. Nessum uses AES 128-bit encryption, prevents unauthorized access by sharing subcarrier-level modulation pattern (called “Tone Map”) between transmitters and receivers, and supports IEEE 802.1X authentication. These features make Nessum not just a connectivity solution—but a secure, future-ready platform for industrial communication.
The figure below shows the advantages of Nessum over Ethernet using the example of building automation.
As a reference, in addition to Nessum, Single Pair Ethernet (SPE) might be recognized as an alternative solution to Ethernet. For a detailed comparison of both technologies, refer to the article HERE.
Now Is the Time to Modernize—Build a Secure Growth Platform with Nessum
The enforcement of the European Cyber Resilience Act has sparked a surge of interest in building robust, high-security IP networks. As businesses face increasing pressure to modernize and comply with new cybersecurity standards, the focus is no longer on whether but on how to make the transition.
That’s where Nessum comes in.
Nessum offers a high-security and cost-effective solution designed to help organizations migrate from legacy network infrastructure to IP-based systems. It’s not just a smart investment; it’s a strategic move. By implementing Nessum, your company can gain a powerful competitive edge and position itself to capture the business opportunities of tomorrow.
