EN 18031-1, What Manufacturers Need to Review for Internet-Connected Radio Equipment
EN 18031-1 is the part of the EN 18031 standards family that focuses on internet-connected radio equipment. For manufacturers, it is closely tied to RED Article 3(3)(d), which deals with protecting networks and network resources from harm or misuse caused by connected radio equipment.
This blog focuses on what that means in practice, what teams usually need to assess, and what should be documented before launch.

What is EN 18031-1?
EN 18031-1:2024 is titled Common security requirements for radio equipment, Part 1: Internet-connected radio equipment. It covers common security requirements for radio equipment capable of communicating over the internet, whether directly or through other equipment.
For many manufacturers, this makes EN 18031-1 the starting point when reviewing whether a connected product falls within the RED cybersecurity requirements.
How EN 18031-1 Connects to Article 3(3)(d)
Article 3(3)(d) applies to internet-connected radio equipment and requires that the equipment must not harm the network or its functioning, and must not misuse network resources in a way that causes unacceptable degradation of service.
For more on how the RED cybersecurity requirements affect connected device manufacturers more broadly, see RED cybersecurity requirements.
In practical terms, EN 18031-1 matters when teams need to show that the product’s connected functions are designed and managed in a way that reduces those risks.
What Manufacturers Should Actually Review
A useful EN 18031-1 review usually starts with the connected behavior of the product. Teams should look at:
how the product connects to the internet
whether it depends on another device or service for connectivity
what remote functions are exposed
how updates are delivered
how accounts, authentication, and permissions are handled
whether insecure behavior could affect network resources or service availability
This is where teams often realize the review cannot stop at the hardware boundary. For many connected products, the relevant scope includes device, app, backend, and update path.
What EN 18031-1 Usually Means for the Technical File
Manufacturers generally need more than a statement that the product is connected and secure. They need documentation that links the product’s internet-connected functions to the requirements and the controls that address them. Typical documentation may include:
product scope and connected architecture
system boundary across device, app, and backend where relevant
identification of connected functions in scope
identification of all security and network assets
requirement mapping for the relevant controls
access-control and authentication documentation
update and change-management documentation
supporting justifications and evidence references
technical file materials tied to the applicable RED requirement
The exact evidence set depends on the product, but the key is that teams can explain what is in scope, what has been reviewed, and how the relevant risk areas are addressed.
Where Teams Usually Get Stuck
The challenge with EN 18031-1 is rarely the title of the standard. The challenge is turning it into a workable internal process. Teams often get stuck when:
the device is reviewed without the connected ecosystem around it
product scope is defined too narrowly
update paths are treated as separate from the compliance review
architecture documentation exists, but is not tied to requirement mapping
compliance, engineering, and security owners are not aligned on who documents what
Manufacturers already familiar with ETSI EN 303 645 will find some overlap in security topics, but EN 18031-1 has a different regulatory role and should be reviewed in that context. That usually leads to slower evidence preparation and more uncertainty later in the process.
What a Good EN 18031-1 Review Should Produce
A strong review should leave the team with:
a clear statement that EN 18031-1 is relevant
a defined scope across the connected system
a view of which functions need deeper review
mapped requirements linked to the product architecture
a structured starting point for technical documentation
a clearer handoff into evidence preparation and next-step compliance work
