The digital landscape of Europe is on the verge of a tectonic shift. While much of the global focus remains on AI regulation and data privacy, a more immediate and operationally demanding set of rules is about to take effect. The European Union’s Cyber Resilience Act (CRA) is no longer a distant legislative concept; it is a fast-approaching reality that threatens to catch the telecommunications industry off guard.
As of September 11, 2026, the first major obligations under the CRA will become mandatory. These rules demand the reporting of actively exploited vulnerabilities and severe security incidents within a window as tight as 24 hours. While the law is ostensibly aimed at "manufacturers," a deeper dive into the regulatory language reveals a complex web of liability that draws in Internet Service Providers (ISPs) and network operators.
To understand the stakes, we spoke with Steven Offerein, VP of Product, Device Intelligence, and Protection Services at CUJO AI. With over 15 years of experience in cybersecurity and senior roles at F-Secure and TalkTalk, Offerein provides a sobering look at how the CRA will redefine the relationship between operators, their hardware, and the millions of connected devices living in customer homes.
Main Facts: Redefining Responsibility in a Connected World
The Cyber Resilience Act is the EU’s first comprehensive attempt to establish horizontal cybersecurity requirements for products with digital elements. Its scope is vast, covering everything from smart fridges and home security cameras to the complex gateways that provide fiber-to-the-home (FTTH) connectivity.
The "Manufacturer" Trap for Operators
One of the most significant misconceptions in the industry is that the CRA is purely a "vendor problem." Offerein points out that many operators may inadvertently fall into the legal definition of a "manufacturer." Under the CRA, if an operator puts its own brand on a gateway or substantially modifies a product’s software in a way that impacts its security posture, they assume the legal obligations of the manufacturer. This includes the responsibility for conformity assessments, vulnerability reporting, and long-term software support.
The 24-Hour Pressure Cooker
The most immediate challenge is the reporting mandate. Starting in September 2026, any entity defined as a manufacturer must provide an "early warning" to the relevant national Computer Security Incident Response Team (CSIRT) and the European Union Agency for Cybersecurity (ENISA) within 24 hours of becoming aware of an actively exploited vulnerability. This is followed by a detailed notification within 72 hours and a final report once the issue is mitigated. For an operator managing millions of Customer Premises Equipment (CPE) units, this requires a level of operational agility that few currently possess.
Visibility as a Regulatory Necessity
The CRA shifts the focus from reactive "firefighting" to proactive lifecycle management. Operators can no longer claim ignorance about what is happening on their networks. To comply with the spirit and letter of the law, they must maintain a clear view of their installed base. As Offerein notes, an operator might know they have shipped 20 million gateways, but they often have zero visibility into the 200 million devices—many of them unpatched or "end-of-life"—connected behind those gateways.
Chronology: The Road to December 2027
The implementation of the CRA is a multi-stage process designed to give the industry time to adapt, yet the staggered deadlines are creating a false sense of security for many.
- September 2024 – Early 2026: The transition period. During this time, the industry is expected to develop the necessary Software Bill of Materials (SBOM) processes and align their procurement strategies with the upcoming requirements.
- September 11, 2026: The Reporting Deadline. This is the first "hard" date. The mandatory reporting of exploited vulnerabilities and incidents becomes law. Crucially, this applies to products already on the market, not just new ones. This means operators must have their incident response and vulnerability management processes ready for their entire existing fleet.
- December 2027: Full Conformity and CE Marking. This is the date most industry players are focused on. From this point forward, all products with digital elements must meet essential security requirements, undergo conformity assessments, and bear the CE mark to be sold in the EU. It also marks the start of mandatory support periods, where manufacturers must guarantee security updates for a defined number of years.
"Most of the industry is treating the CRA as a December 2027 problem," says Offerein. "What they are missing is that the reporting obligations arrive over a year earlier, and they apply to the legacy hardware already in customers’ homes."
Supporting Data: The Scale of the Shadow IoT Problem
The technical challenge of the CRA is best understood through the lens of scale. The modern "connected home" has evolved far beyond a single laptop and a smartphone.
The Device Multiplier
Internal data from CUJO AI, which protects over 60 million households worldwide, suggests a "device multiplier" effect. For every gateway an operator manages, there are typically 10 to 15 connected devices behind it. In a network of 20 million gateways, an operator is effectively the steward of a 300-million-device ecosystem.
The Identification Gap
A significant portion of these devices—often referred to as "Shadow IoT"—identify themselves inconsistently. MAC address randomization and generic hardware signatures make it difficult for standard network tools to distinguish between a secure high-end laptop and a $15 smart plug with hardcoded passwords.
The "Abandoned" Device Reality
Offerein highlights a grim statistic for cybersecurity professionals: a vast percentage of the current IoT population consists of "abandoned" devices. These are products whose manufacturers have gone bankrupt, or legacy models that have reached their official end-of-support. These devices will never receive a patch for new vulnerabilities (CVEs). Under the CRA framework, while the manufacturer’s responsibility might have technically ended, the risk remains on the operator’s network.
Official Responses and Industry Insights
The response from the telecommunications sector has been a mix of lobbying for clarity and a scramble for technical solutions. The core of the debate lies in where the manufacturer’s responsibility ends and the operator’s begins.
The Role of Device Intelligence
Steven Offerein argues that "Device Intelligence" is the bridge between regulatory requirements and operational reality. "No platform makes you CRA compliant—compliance is a process," he explains. "But device intelligence gives you the data to fuel that process. When a vulnerability is disclosed, you need to be able to say, ‘We have exactly 342,000 affected devices in these specific markets,’ rather than guessing."
The Network as a Safety Net
For devices that cannot be patched, Offerein suggests that the operator’s network-level security becomes the only viable mitigation strategy. By using the gateway to inspect traffic patterns, operators can block known exploit signatures and isolate compromised devices, effectively "virtually patching" a device that the manufacturer has long since forgotten.
RFP Evolution
The CRA is already changing how operators approach procurement. Historically, Request for Proposals (RFPs) for gateways were dominated by two factors: price and hardware performance (Wi-Fi speeds). Now, operators are asking for:
- Software Bill of Materials (SBOM): A complete inventory of every software component used in the device.
- Guaranteed Support Periods: Legal commitments for how many years security updates will be provided.
- Coordinated Disclosure Processes: Clear protocols for how the vendor will notify the operator of a breach.
Implications: A New Era of Sustainability and Security
The long-term impact of the Cyber Resilience Act will be felt across the entire electronics lifecycle, from design to disposal.
The End of "Disposable" Tech
The CRA essentially mandates a "Right to Security." By forcing manufacturers to define and honor support periods, the EU is making it harder for companies to sell cheap, insecure hardware and then abandon it. This could lead to a significant reduction in e-waste, as hardware that remains physically functional will no longer be rendered obsolete by a lack of basic security software.
Operational Fire Drills
For operators who fail to invest in visibility and automated reporting, every new vulnerability disclosure (CVE) will become an organizational "fire drill." The 24-hour reporting window does not allow for manual audits of procurement databases. The CRA will force a shift toward automated, real-time asset management within the network.
The Sustainability Paradox
There is a concern that the CRA might force operators to pull perfectly functional CPE from the field earlier than intended if the original vendor cannot or will not provide security updates. However, Offerein offers a more optimistic view: "The more interesting outcome could be longer, better-supported lifecycles. It gives vendors a way to account for support commitments commercially, ensuring hardware is properly supported for longer, alongside additional protections where updates are no longer available."
Conclusion: The Three Steps to Readiness
As the September 2026 deadline approaches, the window for preparation is closing. Offerein suggests that operators prioritize three specific actions:
- Settle the Legal Role: Determine, product by product, whether the operator acts as a manufacturer, importer, or distributor. This is a legal exercise that dictates every subsequent technical requirement.
- Rehearse the Reporting Path: Establish a clear internal escalation process that can move from "vulnerability detected" to "official notification" within 24 hours. This must be a "warm" process, not a document sitting on a shelf.
- Invest in Installed-Base Visibility: Move beyond procurement databases. Operators need a live, continuous view of what is connected to their gateways to map vulnerabilities to real device populations instantly.
The Cyber Resilience Act is more than just a new set of rules; it is a fundamental shift in the "duty of care" for the digital age. For European operators, the choice is clear: embrace the transparency the CRA demands, or face the consequences of being the "manufacturer of record" in an increasingly hostile threat landscape.
