As of 1 April 2025, operators of critical infrastructure in Switzerland will be required to report cyberattacks to the National Cyber Security Centre (NCSC) within 24 hours of discovery. This measure, introduced by the Federal Council, is part of an amendment to the Information Security Act (ISA) and aims to enhance cybersecurity coordination and response capabilities.

The reporting obligation applies to key sectors, including energy and water suppliers, transport companies, and public administrations at the cantonal and communal levels. Reports must be submitted when an attack disrupts critical infrastructure, compromises or manipulates information, or involves blackmail, threats, or coercion. Failure to comply may result in financial penalties, which will be enforceable from 1 October, allowing a six-month adjustment period before sanctions take effect.

To facilitate compliance, the NCSC will provide a reporting form on its Cyber Security Hub, with an alternative email submission option for organisations not yet registered on the platform. Initial reports must be submitted within 24 hours, followed by a detailed report within 14 days.

The Federal Council has also approved the Cybersecurity Ordinance, which outlines implementation provisions, reporting exemptions, and mechanisms for information exchange between the NCSC and other authorities. Consultations on the ordinance reflected broad support for streamlined reporting processes, ensuring alignment with existing obligations, such as those under data protection laws.

Additionally, from 1 April, the National Cyber Security Centre will officially change its name as part of its transition into a federal office within the Department of Defence, Civil Protection and Sport (DDPS).

This regulatory update aligns Switzerland with international cybersecurity practices, including the EU's NIS Directive, which has required cyber incident reporting since 2018.
