The Cybersecurity Information Sharing Act of 2015 (“CISA 2015”), which provides liability protections and other safeguards for sharing certain cybersecurity information with the U.S. federal government and private entities, was reauthorized as part of the funding bill enacted on February 3, 2026. CISA 2015’s information‑sharing provisions, which had been scheduled to sunset on January 30, 2026, will now remain in effect through September 30, 2026.Continue Reading Cybersecurity Information Sharing Act of 2015 Reauthorized Through September 2026

On 20 January 2026, the European Commission published a proposal for a Regulation to update and replace the Cybersecurity Act (Regulation 2019/881). The proposal—known as the Cybersecurity Act 2 (CSA2)—forms part of a wider package aimed at modernizing and streamlining the EU’s cybersecurity framework and is closely linked to the…

On 20 January 2026, the European Commission published a proposal to amend the Directive (EU) 2022/2555 (NIS2) as part of a broader package to streamline the EU’s cybersecurity framework. The Commission also issued a proposal to revise the EU Cybersecurity Act (CSA2), which we cover in a separate blog post.

The proposed amendments build on earlier streamlining efforts in the Commission’s Digital Omnibus Package—published on 19 November 2025—which introduced the first wave of technical adjustments to NIS2. Those earlier amendments focused on creating a single framework for reporting cyber incidents and clarifying how NIS2 interacts with sectoral regimes such as the CER Directive and DORA.

With this proposal, the Commission now aims to clarify the scope of the law, harmonize technical measures, introduce certification‑based compliance pathways, and strengthen cross‑border supervision through an expanded role for ENISA.

Below, we summarize the main elements of the proposal and what they could mean for entities in scope of NIS2.Continue Reading European Commission Proposes Targeted Amendments to NIS2 to Simplify Compliance and Align With Proposed Cybersecurity Act 2

On 5 December 2025, the Act Transposing the NIS 2 Directive and Regulating Key Aspects of Information Security Management in the Federal Administration (Gesetz zur Umsetzung der NIS-2-Richtlinie und zur Regelung wesentlicher Grundzüge des Informationssicherheitsmanagements in der Bundesverwaltung (“NIS2UmsG”) (see here, in German only) became binding in Germany. According to the Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik (“BSI”) (see here, in German only), roughly 29,500 companies will have to comply with the increased cybersecurity requirements adopted by the NIS2UmsG.Continue Reading Germany Transposes NIS 2 Directive – Increased Cybersecurity Requirements for Businesses

On December 16, 2025, the U.S. National Institute of Standards and Technology (“NIST”) published a preliminary draft of the Cybersecurity Framework Profile for Artificial Intelligence (“Cyber AI Profile” or “Profile”).  According to the draft, the Cyber AI Profile is intended to “provide guidelines for managing cybersecurity risk related to AI…

On December 11, 2025, the U.S. Cybersecurity and Infrastructure Security Agency (“CISA”) released its Cybersecurity Performance Goals 2.0 (“CPG 2.0”), an update to its core set of recommended cybersecurity practices for critical infrastructure owners and operators, which we previously wrote about here.  Established by the 2021 National Security Memorandum…

On November 20, 2025, the Securities and Exchange Commission (“SEC”) announced that it was voluntarily dismissing the case it brought against SolarWinds Corp. (“SolarWinds”) and its Chief Information Security Officer, Timothy Brown, regarding the company’s security practices and related statements in connection with the “Sunburst” cybersecurity incident. The SEC stated in a brief release that its decision to dismiss with prejudice the case against SolarWinds and Mr. Brown was “in the exercise of its discretion” and “does not necessarily reflect the Commission’s position on any other case.”Continue Reading SEC Voluntarily Dismisses SolarWinds Litigation

As the UK Government has recognized, cyber incidents—such as Jaguar Land Rover, Marks and Spencer, Royal Mail and the British Library—are costing UK businesses billions annually and causing severe disruption. The Government recognizes that cybersecurity is a critical enabler of economic growth (“we cannot have growth without stability”), and that the current laws have “fallen out of date and are insufficient to tackle the cyber threats faced by the UK.” Accordingly the UK Government this week published its long-awaited Cyber Security and Resilience Bill (the “Bill”), which will amend the existing Network and Information Systems Regulations 2018 (the “NIS Regulations”), and grant new powers to regulators and the Government in relation to cybersecurity.

The NIS Regulations are the UK’s pre-Brexit implementation of Directive (EU) 2016/1148 (the “NIS Directive”), which established a “horizontal” cybersecurity regulatory framework covering essential services in five sectors (transport, energy, drinking water, health, and digital infrastructure) and some digital services (online marketplaces, online search engines, and cloud computing services). EU legislators replaced NIS Directive in 2022 with the “NIS2” Directive, which Member States were meant to transpose into national law by October of last year (although many are still late in doing so. See our post on NIS2 here for an overview of the requirements of NIS2).

The Bill is the UK’s effort at modernizing the framework originally set out in the NIS Directive. In its current form, the Bill will:

  • Significantly expand the scope of the NIS Regulations—to cover, among other things, data centers and managed service providers—and impose additional substantive obligations on covered organizations.
  • Increase potential fines—up to GBP 17m or 4% of the worldwide turnover of an undertaking—and extend the powers of competent authorities to share information with one another, issue guidance, and take enforcement action.
  • Establish a framework for future changes to the NIS Regulations, mechanisms for competent authorities to impose specific cybersecurity requirements on covered organizations, and greater Government direction of cybersecurity matters.

Below, we set out further detail on five major changes in UK cybersecurity regulation arising from the Bill.Continue Reading Five major changes to the regulation of cybersecurity in the UK under the Cyber Security and Resilience Bill

The Cybersecurity Information Sharing Act of 2015 (“CISA 2015”), which provides protections for sharing cybersecurity threat information with the federal government and others, was reauthorized under the funding bill to reopen the federal government, which was enacted on November 12, 2025.  The information sharing mechanisms and protections under CISA 2015, which had previously sunset on September 30, 2025, will now extend through January 30, 2026.Continue Reading Cybersecurity Information Sharing Act of 2015 Reauthorized Through January 2026

On October 21, 2025, the New York State Department of Financial Services (“NYDFS”) issued an industry letter (the “Guidance”) highlighting the cybersecurity risks related to Covered Entities’ use of Third-Party Service Providers (“TPSPs”) and providing strategies to address these risks. The Guidance is addressed to all Covered Entities subject to NYDFS’s cybersecurity regulation codified at 23 NYCRR Part 500 (“Cybersecurity Regulation”), which requires Covered Entities to implement a comprehensive cybersecurity program that includes written policies addressing TPSP risks as well as due diligence, contractual requirements, and periodic assessments for TPSPs. While the Guidance is explicit that it “does not impose any new requirements” beyond those already included in the Cybersecurity Regulation, it provides significant additional detail to clarify how to comply with existing requirements and offers industry best practices to mitigate TPSP-related cyber risks. As the Guidance suggests that NYDFS will continue to focus on TPSP-related cyber risks, Covered Entities should consider reviewing their TPSP oversight and management against the specific recommendations from the Guidance and adjusting their practices where appropriate. Alongside a review of TPSP oversight and management, Covered Entities may also consider reviewing their implementation of the provisions of the Cybersecurity Regulation requiring multifactor authentication, asset management, and data retention, which take effect on November 1, 2025.Continue Reading NYDFS Publishes Industry Guidance on Managing Cyber Risks Related to Third-Party Service Providers
