The qualification stages
ANCI qualifies Vital Importance Operators in successive stages, each formalized by a reasoned exempt resolution.
Stage 1
- Exempt Resolution 50, September 9, 2025
- Published in the Diario Oficial on September 16, 2025
Stage 2
- Preliminary Exempt Resolution 85 (April 21, 2026) and public consultation
- Definitive Exempt Resolution 187 (July 21, 2026), published in the Diario Oficial on July 24, 2026
What the definitive Stage 2 roster contains
Resolution 187 qualifies 155 institutions across the six new second-stage sectors and adds first-stage operators that were missing from the preliminary roster.
- Fuel transport, storage and distribution: 25 institutions
- Drinking water and sanitation: 18
- Land, air, rail and maritime transport, including its infrastructure: 40
- Public-service concessionaires: 32
- Social-security benefit administration: 25
- Pharmaceutical production and research: 15
- It also adds essential-service operators from the first stage (health, electricity, digital infrastructure and services) that were not on the preliminary roster of Resolution 50/2025
- Postal and courier services, foreseen for this stage, ended with no qualified entities: the recitals invoke the free-competition doctrine of the Supreme Court (case 47.555-2016)

Frequently asked questions
The most common questions about the OIV list and its qualification.
What is the list of Operators of Vital Importance (OIV)?
It is the registry of public and private entities qualified by the National Cybersecurity Agency (ANCI) as OIV under Law 21.663. Qualification is made by reasoned exempt resolution and formally notified to each entity. The list is officially published by ANCI.
How many OIV qualification stages has ANCI published?
Four milestones: Exempt Resolution 50 (September 2025) approved the first-stage preliminary roster and Exempt Resolution 87 (December 2025) its definitive roster, with 915 institutions. In the second stage, Exempt Resolution 85 (April 2026) approved the preliminary roster and Exempt Resolution 187 (July 2026) the definitive one, with 155 institutions across six new sectors plus first-stage operators that were missing.
How is each entity qualified as OIV?
ANCI applies objective criteria from the Regulation of Law 21.663: dependence on third parties, mass user base, systemic sectoral impact and availability of substitutes. The qualification is notified with the supporting resolution and triggers reinforced obligations.
Can a company challenge its OIV qualification?
Yes. The qualifying resolution is subject to the general administrative remedies under Law 19.880 and, once the administrative phase is exhausted, to the corresponding judicial actions. Deadlines are short and specialised legal counsel is critical.
What immediate obligations does being on the list trigger?
Implementing an information-security management system, an operational-continuity plan, appointing a Cybersecurity Delegate, reporting cyber incidents to ANCI within short deadlines and allowing audits. Non-compliance exposes the entity to sanctions under Law 21.663.
