The EU's "Cyber ​​Resilience Act" officially comes into effect, and technology companies face a "countdown" system for vulnerability reporting

📅 2026-09-11

Abstract:

The European Union officially launched key provisions of the Cyber ​​Resilience Act on September 11, imposing stricter cybersecurity reporting obligations on digital product manufacturers and software developers. According to the new regulations, once companies discover that their products have security vulnerabilities that are being exploited by hackers, they must report them to the EU cybersecurity agency within a very short period of time, otherwise they may face severe penalties in the future.

According to the requirements of the bill, when a company discovers that a vulnerability in its product has been actually exploited, it must first issue an early warning notification to the European Cybersecurity Agency (ENISA) within 24 hours; then submit a more detailed description of the situation within 72 hours, including the nature of the vulnerability, its scope of impact, and the mitigation measures that have been taken; after the vulnerability is repaired, it must submit a final report within 14 days. If it involves a serious cybersecurity incident rather than a simple vulnerability exploit, the deadline for submitting the final report is extended to one month.

The EU stated that the main purpose of this system is to improve the transparency and responsiveness of the entire digital product ecosystem. By forcing vendors to quickly disclose and report security risks, the EU hopes to reduce the harm caused by long-term hiding of vulnerabilities and improve the overall security level of IoT devices, software platforms and connected products.

Unlike many cybersecurity regulations, the new system not only applies to new products launched in the future, but also covers digital products already on the market. This means that companies cannot just establish a security response mechanism for new products, but must establish a rapid vulnerability reporting system for existing software, hardware, and products under ongoing maintenance. Once relevant products are found to be under attack or have exploited vulnerabilities, the statutory reporting process will be triggered.

The scope of the new regulations is quite broad. In addition to local EU companies, all foreign companies selling digital products and services to the EU market also need to comply with relevant requirements. Whether they are software developers, hardware manufacturers, consumer electronics companies, or Internet of Things equipment suppliers, as long as their products enter the EU market, they may be subject to restrictions.

In order to help companies adapt to the new system, the European Commission has issued a series of practical guidance documents, and the European Cybersecurity Agency has established a unified reporting platform to receive and manage vulnerability and security incident reports submitted by companies. Relevant agencies hope to reduce corporate compliance costs through standardized processes while ensuring that regulatory authorities can timely grasp network security risk dynamics.

While the vulnerability reporting system will be implemented starting today, the full compliance requirements of the Cyber ​​Resilience Act will be implemented in phases. According to the established timetable, complete requirements, including comprehensive obligations such as product certification, technical documentation and CE marking, will officially become mandatory in December 2027.

The background to the introduction of the bill is that global cyber attacks have increased frequently in recent years, and a large number of smart devices and Internet-connected products have been found to have vulnerabilities that have not been repaired for a long time. The EU believes that some manufacturers lacked the motivation to disclose and deal with safety issues in a timely manner in the past, so it is necessary to establish unified standards through legislation and use legal responsibilities to promote companies to improve safety management levels.

Analysts believe that this new regulation may force the technology industry to redesign its internal security response processes. In the future, enterprises will not only have to discover vulnerabilities faster, but they will also have to ensure that assessment, notification and remediation are completed within the specified time. For large technology companies, this means that more resources need to be invested in building round-the-clock network security teams; while for small and medium-sized developers, they may face considerable compliance pressure.

With the gradual implementation of the Cyber ​​Resilience Act, the EU is becoming one of the regions with the strictest cybersecurity regulations in the world. In the next few years, whether this system can truly reduce the abuse of loopholes and improve the digital security level of consumers and enterprises will become an important issue of concern to the global technology industry.
