ETSI EN 303 645 vs RED Cybersecurity Delegated Act

Use ETSI EN 303 645 to structure consumer IoT security controls and evidence, then keep a separate RED analysis for radio-equipment legal scope, CE documentation, and EU market-access decisions.

This page is grounded in ETSI consumer IoT sources. RED conclusions are intentionally limited to comparison planning and must be checked against RED sources before use.

Overview

ETSI EN 303 645 and the RED Cybersecurity Delegated Act can appear in the same connected-product program, but they should not be collapsed into one checklist. ETSI EN 303 645 specifies baseline security and data-protection provisions for consumer IoT devices connected to network infrastructure and their interactions with associated services. ETSI TS 103 701 explains how to assess those provisions through a DUT, supplier organization, test laboratory, ICS, IXIT, test plan, and verdict process. Use this page to decide what ETSI evidence can support a RED workstream and where the RED file still needs separate legal and conformity-assessment grounding.

Side-by-side comparison

ETSI EN 303 645 vs RED Cybersecurity Delegated Act: evidence boundary

A narrow comparison for connected-product teams deciding what ETSI EN 303 645 can prove, what RED must prove separately, and when evidence can be bridged without overclaiming.

Review all sources
First framework
ETSI EN 303 645

A consumer IoT cybersecurity baseline for network-connected consumer devices and their interactions with associated services, with TS 103 701 providing an assessment method.

Second framework
RED Cybersecurity Delegated Act

A RED legal and conformity-assessment workstream for radio equipment. This page flags RED evidence questions but does not treat ETSI grounding as sufficient for RED conclusions.

Comparison row 1

Scope and covered activity

ETSI EN 303 645

ETSI EN 303 645 covers consumer IoT devices connected to network infrastructure and their interactions with associated services. Associated services are considered for interactions, but the services themselves are outside the standard's scope.

RED Cybersecurity Delegated Act

RED scope must be confirmed from RED sources: whether the product is radio equipment, which delegated cybersecurity requirements apply, and which EU conformity route is available cannot be concluded from the assigned ETSI grounding alone.

Operational implication

Start with two scope records: an ETSI consumer IoT boundary for control evidence and a separate RED radio-equipment boundary for legal and CE-file decisions.

Comparison row 2

Who must act

ETSI EN 303 645

For an ETSI assessment, the supplier organization requests the DUT assessment, provides ICS and IXIT information, and coordinates across parties such as manufacturers, service providers, component suppliers, application developers, vendors, or distributors.

RED Cybersecurity Delegated Act

RED ownership should be assigned separately to the manufacturer or other RED economic-operator roles after RED source review. The assigned ETSI sources do not define those RED duties.

Operational implication

Do not give one compliance owner both jobs. Assign ETSI evidence owners for ICS/IXIT and test support, then assign RED owners for legal scope, conformity assessment, and technical documentation.

Comparison row 3

Trigger or threshold

ETSI EN 303 645

ETSI EN 303 645 applies when the team is assessing a consumer IoT device and its relevant interactions with associated services against the baseline provisions. Conditional ETSI provisions then depend on product facts such as whether passwords, update mechanisms, telemetry, consent-based personal-data processing, or hard-coded device identities exist.

RED Cybersecurity Delegated Act

RED cybersecurity triggers must come from RED sources, not from ETSI EN 303 645. Treat radio-equipment status, product category, data-processing facts, and applicable dates as RED research items unless already grounded in a RED file.

Operational implication

Use an ETSI condition matrix for provisions and a separate RED trigger matrix for legal applicability. Do not infer RED applicability from the presence of an ETSI control.

Comparison row 4

Core obligations

ETSI EN 303 645

ETSI EN 303 645 turns into product-security work: no universal default passwords, vulnerability disclosure, software updates, sensitive security parameter storage, secure communication, attack-surface reduction, software integrity, personal-data security, resilience, telemetry review, user-data deletion, secure usability, and input validation.

RED Cybersecurity Delegated Act

RED core obligations should be written only after RED source review. The ETSI provisions can support cybersecurity evidence, but the assigned ETSI grounding does not establish RED legal duties or CE-file completeness.

Operational implication

Build the ETSI action list from clauses 5 and 6, then add RED duties in a separate source-linked column instead of renaming ETSI provisions as RED obligations.

Comparison row 5

Evidence and records

ETSI EN 303 645

ETSI evidence should include the DUT identification, ICS support claims and details, IXIT entries, user documentation, conceptual and functional test results, verdict rationale, and any external evidence accepted for a provision.

RED Cybersecurity Delegated Act

RED evidence should be kept in a separate technical-file record until RED-specific scope, requirements, standards status, conformity assessment, and authority-facing documentation are confirmed.

Operational implication

Create a traceability matrix with source, product version, claim, ETSI artifact, RED artifact, owner, and gap status. Shared evidence should be tagged as supporting evidence, not proof that both regimes are complete.

Comparison row 6

Timing and cadence

ETSI EN 303 645

ETSI timing is product-security timing: defined support period, timely vulnerability action, timely security updates, periodic update checks, reassessment after product or service changes, and assessment use of the most up-to-date DUT software.

RED Cybersecurity Delegated Act

RED timing must be tracked separately from RED sources. The assigned ETSI grounding does not establish the RED delegated-act application date, transition plan, or recertification cadence.

Operational implication

Maintain separate clocks: ETSI support and assessment timing for security operations, and RED legal timing for EU market-access decisions.

Comparison row 7

Enforcement or assurance route

ETSI EN 303 645

ETSI EN 303 645 is a baseline standard. TS 103 701 can support first-party, second-party, third-party, certification, and conformance-declaration schemes, but defining a certification or conformance-declaration scheme is outside TS 103 701.

RED Cybersecurity Delegated Act

RED enforcement and conformity-assessment route must be determined under RED sources. Do not use ETSI assessment wording to imply CE acceptance, notified-body status, or market-surveillance outcomes.

Operational implication

Use ETSI assessment results as assurance evidence only. Escalate legal, CE-marking, harmonised-standard, notified-body, or market-surveillance questions to RED-specific source review.

Comparison row 8

Overlap and reuse

ETSI EN 303 645

ETSI overlap exists at the control and evidence level: a well-scoped ETSI assessment can show implemented cybersecurity measures for the consumer IoT product.

RED Cybersecurity Delegated Act

RED overlap exists only after a RED requirement has been mapped to the same product facts and evidence. If the RED source or harmonised-standard position is unknown, mark the row as a gap.

Operational implication

Reuse evidence by reference, not by renaming. Keep the ETSI result, RED requirement, common product facts, and remaining RED gaps visible in the same row.

Comparison row 9

Practical decision rule

ETSI EN 303 645

Use ETSI EN 303 645 as the controlling source when the decision is about consumer IoT baseline controls, ICS/IXIT content, assessment evidence, or support for a product-security claim.

RED Cybersecurity Delegated Act

Use RED sources as the controlling source when the decision is about radio-equipment scope, delegated cybersecurity applicability, conformity assessment, CE technical documentation, or market access.

Operational implication

The safest comparison output is a bridge table: ETSI evidence accepted, RED source checked, RED gap remaining, and owner assigned.

Practical decision rule

How to choose the controlling source

  • Choose ETSI EN 303 645 when the question is whether a consumer IoT control is implemented, documented, tested, or supported in the ICS/IXIT evidence.
  • Choose RED when the question is whether radio equipment meets EU delegated cybersecurity, conformity-assessment, CE-file, or market-access requirements.
  • Use both only through a bridge table that keeps ETSI control evidence and RED legal conclusions separate.
Section 1

What ETSI EN 303 645 can and cannot answer

ETSI EN 303 645 is a consumer IoT cybersecurity baseline. It is written for network-connected consumer IoT devices and their interactions with associated services, while associated services themselves are outside the standard's scope.

That makes it useful for product-security evidence: passwords, vulnerability reporting, secure updates, secure storage of sensitive security parameters, secure communication, attack-surface minimization, software integrity, personal-data security, resilience, telemetry review, user-data deletion, installation and maintenance usability, input validation, and data-protection transparency. It does not, by itself, decide whether a product is radio equipment, whether RED Article 3(3) is triggered, or which CE conformity-assessment route applies.

  • Use ETSI EN 303 645 when the question is about consumer IoT security controls and implementation evidence.
  • Use a separate RED source analysis when the question is about EU radio-equipment scope, legal obligations, CE marking, or market-surveillance expectations.
  • Treat any ETSI-to-RED reuse as supporting evidence until a RED-specific source confirms the same scope, requirement, and conformity route.
Section 2

Evidence boundary for a comparison

Start the ETSI side with the consumer IoT product boundary: the device, firmware, network interfaces, user interfaces, update mechanism, telemetry, personal-data processing, user-data deletion functions, user instructions, and the interactions with associated services that are necessary to provide the product's intended functionality.

TS 103 701 assesses a specific Device Under Test. The supplier organization provides the ICS and IXIT, and the test laboratory uses those documents to derive a test plan. That evidence model is more precise than a general policy checklist and is the right unit for any later RED bridge.

  • Identify the DUT and its most up-to-date software version before mapping controls.
  • Separate on-device functionality from associated-service interactions so the comparison does not overclaim the ETSI scope.
  • Keep ICS support claims, IXIT details, user documentation, and test results linked to the same product configuration.
Section 3

Where evidence reuse is strongest

Evidence reuse is strongest where the RED workstream needs proof of actual cybersecurity controls in a connected consumer product and the ETSI evidence is tied to the same shipped configuration. Examples include removal of universal default passwords, vulnerability disclosure handling, secure software updates, secure communication, secure handling of sensitive security parameters, telemetry anomaly review, user-data deletion, and input validation.

Reuse should still be documented as a bridge, not a substitution. A completed ETSI control record can explain what was implemented and tested, but it does not automatically prove that a RED essential requirement, harmonised-standard route, notified-body decision, or CE technical file is complete.

  • Reuse ETSI records only when the product version, software, interfaces, associated services, and user-facing information match the RED evidence boundary.
  • Carry over the actual ETSI artifacts: ICS rows, IXIT entries, conceptual-test conclusions, functional-test results, and external-evidence references.
  • Add a RED bridge note that names the RED requirement being supported and what remains outside the ETSI evidence.
Section 4

How to document unsupported or non-applicable items

ETSI EN 303 645 includes an Implementation Conformance Statement pro forma. The support column can mark provisions as supported, not supported, or not applicable. The detail column is where the team records implemented measures, reasons a provision is not supported, or the rationale for a not-applicable decision.

TS 103 701 makes those entries assessable. It requires the supplier organization to complete the ICS correctly, provide IXIT information for provisions claimed as supported, and justify N/A or not-supported positions so the test laboratory can verify the claim and assign reproducible verdicts.

  • Do not write a bare N/A for an ETSI provision; include the condition or feature reason that makes it not applicable.
  • Do not mark a mandatory provision unsupported and still describe the product as conforming without explaining the failed claim.
  • Use RED gap language when the assigned ETSI sources do not establish a RED obligation or conformity route.
Section 5

Implementation checklist for the ETSI-to-RED bridge

Use this checklist when a product team wants to reuse ETSI EN 303 645 work in a RED cybersecurity file. The output should be a traceable bridge, not a merged checklist with unsupported legal conclusions.

  • Confirm the product is a consumer IoT device for the ETSI side and record any associated services needed for intended functionality.
  • Identify the DUT, software version, user documentation, network interfaces, user interfaces, update paths, telemetry, data deletion functions, and personal-data processing.
  • Complete or reference the ICS and IXIT entries for each claimed ETSI provision.
  • Attach conceptual and functional test evidence, including the test plan basis and verdicts where TS 103 701 assessment has been performed.
  • Create a separate RED column that states whether RED source coverage has been verified, which RED requirement the ETSI evidence may support, and what RED-specific evidence is still missing.
Section 6

Common mistakes to avoid

The main risk is overclaiming. A team may have useful ETSI EN 303 645 security evidence, but still lack RED-specific scope, harmonised-standard status, conformity-assessment, technical-file, or CE-marking analysis.

The second risk is losing traceability. ETSI evidence is most useful when it names the product version, support-period information, associated-service dependencies, ICS status, IXIT detail, test method, verdict, and external evidence being relied on.

  • Do not present ETSI EN 303 645 as a RED legal requirement or RED presumption-of-conformity route unless a RED source separately supports that claim.
  • Do not reuse ETSI evidence for a product variant, firmware version, app, cloud service, or data-processing flow that was not inside the assessed boundary.
  • Do not hide conditional or unsupported provisions in narrative text; put the rationale in the ICS detail or bridge record.
  • Do not cite local source reference filesnames, screenshots, or private working notes as public sources.
