SHERIDAN, WYOMING - April 2, 2026 - Network architects and compliance teams designing next-generation infrastructure face a binding constraint: 6G Integrated Sensing and Communications (ISAC) systems introduce sensing capabilities that existing security and privacy frameworks do not cover, and ETSI's newly published GR ISC 004 defines the technical and non-technical requirements that vendors and operators must address before these systems can be responsibly deployed.
What ETSI GR ISC 004 covers
The European Telecommunications Standards Institute's Industry Specification Group on Integrated Sensing and Communications published ETSI GR ISC 004, a structured report cataloguing 19 key issues spanning security, privacy, trustworthiness, and sustainability in 6G ISAC environments. Of those 19 issues, 15 address security and privacy, while the remaining four focus on sustainability dimensions unique to systems that sense as well as communicate.
The security and privacy cluster targets concrete threat vectors: unauthorised use of 6G infrastructure for sensing third parties, target-based eavesdropping, over-the-air signal manipulation, and insecure transport or storage of sensing data. The report also addresses consent and transparency mechanisms for sensing both connected and non-connected humans, confidentiality requirements in non-public or sensitive spaces, and the immutability of stored sensing records. These are not aspirational guidelines - the report consolidates potential technical and non-technical requirements that future 6G systems should meet to ensure ISAC services are trustworthy and resilient.
Sustainability and AI considerations in 6G ISAC
The four sustainability issues in GR ISC 004 cover power consumption, spectrum efficiency, environmental footprint, and health considerations - areas where ISAC's dual-function design creates trade-offs that single-purpose communication systems do not face. A system that continuously senses its environment draws more processing power and spectrum resources than one that only transmits, making energy accounting a design-stage obligation rather than a retrofit.
AI-based data processing appears explicitly in the report as a risk category. ISAC systems that feed sensing outputs into machine-learning pipelines raise questions about data confidentiality, model bias in human-detection scenarios, and auditability of automated decisions. GR ISC 004 addresses secure handling of AI-processed sensing data as a distinct requirement, signalling that regulators and standards bodies will treat AI integration in 6G sensing as a first-class compliance surface rather than an implementation detail.
Business impact
Telecom equipment vendors and network operators building 6G ISAC roadmaps now have a formal ETSI reference document that shapes procurement and certification decisions. Technology evaluation teams can use GR ISC 004's 15 security and privacy issues as a structured checklist for assessing vendor submissions, replacing ad hoc risk assessments with a standardised baseline. Any vendor unable to demonstrate coverage of the report's requirements - particularly around unauthorised sensing protections and sensing-data immutability - faces disqualification from procurement cycles where ETSI compliance is a contractual condition.
Compliance and legal officers in sectors where non-connected individuals may be sensed - healthcare facilities, retail environments, public transport - must assess whether existing consent and transparency frameworks satisfy GR ISC 004's privacy-preserving mechanism requirements. For these groups, the report moves 6G ISAC from a future-network consideration into an active regulatory planning item for 2026 and 2027 budget cycles. Sustainability officers responsible for corporate environmental reporting also gain a scoped set of performance metrics - power consumption, spectrum efficiency, and environmental footprint - that can be incorporated into supplier due-diligence criteria for next-generation network contracts.
