After the preparatory phase, in **2026** organizations enter the **full implementation of the [European NIS 2 Directive](https://www.gazzettaufficiale.it/atto/serie_generale/caricaDettaglioAtto/originario?atto.dataPubblicazioneGazzetta=2024-10-01&atto.codiceRedazionale=24G00155&elenco30giorni=false)**, with effective obligations and operational responsibilities.
During **January**, the main development was the entry into force of **the obligation to notify significant incidents**, with defined timelines for early warning, detailed notification and final report.
Below are the main **upcoming deadlines for 2026**, which will guide organizations in the full implementation of the **NIS 2 Directive**.
## Sectoral guidelines NIS 2 Directive
Between **February and September 2026**, ACN progressively publishes the **guidelines dedicated to each sector**.
These documents aim **to provide practical and concrete indications**, adaptable to different operational contexts, in order to support companies in implementing **security measures** in a proportionate way, avoiding excessive or insufficient approaches.
### April-June 2026: Categorization model and communication of services
By the **beginning of April 2026**, [**ACN**](https://www.acn.gov.it/portale/home) plans to develop and make available the **categorization model of activities and services**, together with the package of long-term obligations.
Subsequently, **between May and June 2026**, organizations will be required to communicate the **list of the activities and services** provided, specifying their type and level of relevance. This step will make it possible to obtain a **clear and structured overview** of business activities in relation to **security obligations**.
### October 2026: Implementation of basic security measures
**31 October 2026** constitutes a **key deadline** in the compliance path. By this date, all organizations must have implemented and made operational the **fundamental security measures**, which concern **key areas** such as:
- **technical protection** of information and operational systems (IT and OT);
- **continuity** of business activities;
- **risk management** and governance;
- **incident management** and **response** (incident response);
- security throughout the **entire supply chain**.
With the end of October, the support and guidance phase by ACN concludes, allowing it **to start inspection activities** and **systematic checks**, while at the same time launching the implementation of **long-term security measures**.
For this reason, it is essential that companies plan the necessary adjustments well in advance, **reducing the risk of operational disruptions** and **possible penalties**.
### Rexguard: centralized management of non-conformities
**Rexguard** is an **integrated platform** developed to simplify and centralize the **management of security incidents, vulnerabilities, non-conformities** and **audit activities** within a single operational environment.
The solution enables organizations to manage these processes more efficiently, improving the **speed of incident response** and supporting compliance with standards and regulations, **including NIS2**.
Thanks to **full activity traceability features**, detailed audit trails and customizable reporting systems, companies can accurately monitor **every phase of the incident management process**, while strengthening the overall **security and governance of IT systems**.
