For organisations in regulated sectors, adopting stricter security measures under the NIS2 directive means focusing more on proactive cybersecurity. This involves implementing robust security practices to reduce the growing cybersecurity risks faced by critical infrastructure operators, digital service providers, and online marketplaces.

Dive into Compliance Obligations

Compliance under the original NIS directive

Under the original NIS directive, organizations had to follow rules like using proper security measures and telling authorities about important incidents. If they didn't follow these rules, they could get fined.

When NIS changed to NIS2, organizations got ready for the new rules by checking and updating their security measures and plans for dealing with incidents. They did things like assessing risks, using the best industry practices, and making sure their network and information systems were secure.

By knowing the differences between NIS and NIS2, organizations got ready for the new rules and kept from getting fined for not following them.

Enhanced compliance requirements in NIS2

NIS2 has stricter compliance requirements than the original NIS directive. It focuses more on security measures for digital service providers, online marketplaces, and search engines.

The regulated sectors under NIS2 include not only energy, transport, and health sectors but also other areas like drinking water supply, waste water management, and digital infrastructure.

NIS2 also imposes harsher penalties for non-compliance, with potential fines of up to 2% of the organization’s global turnover, to enhance cybersecurity measures.

Incident Reporting under NIS and NIS2

Incident reporting framework in NIS

The incident reporting framework in NIS is a structured system designed to report and respond to cybersecurity incidents. It has clear guidelines for what constitutes an incident, reporting timelines, and procedures to follow when an incident occurs.

NIS2 has revised incident reporting timelines and thresholds to provide a more comprehensive overview of cybersecurity incidents. The main difference between NIS and NIS2 is in the specific reporting requirements, such as the types of incidents to report, thresholds, and deadlines. This ensures that both NIS and NIS2 can adapt to new threats in a timely manner.

Revised incident reporting timelines and thresholds in NIS2

Revised incident reporting timelines and thresholds in NIS2 require digital service providers and operators of essential services to report cybersecurity incidents to relevant national authorities within a specific timeframe.

The reporting timelines vary depending on the severity of the incident, with shorter deadlines for more serious events. Additionally, NIS2 introduces new thresholds for incident reporting, including a broader scope of digital service providers and operators of essential services that are required to comply with the directive.

These changes differ from the original NIS directive, which had more limited reporting requirements and thresholds. For example, NIS2 lowers the threshold for digital service providers, expanding the types of organizations that are now subject to reporting requirements.

These revised timelines and thresholds in NIS2 represent a concerted effort to enhance cybersecurity and address the evolving digital landscape, ensuring that critical infrastructure and digital services are adequately protected from cyber threats.

Penalties for Non-compliance

Sanctions and fines under the original NIS directive

Under the original NIS directive, organizations could be fined up to €100,000 for not following the rules. The sanctions could include warnings, temporary bans on certain activities, and exposing the infringement publicly.

In the newer NIS2, the fines for not following the rules have been increased to up to €20 million or up to 4% of the operator's global annual turnover. NIS2 also introduces structural changes that require member states to create a national strategy for the security of network and information systems.

To enforce these sanctions and fines, the directive requires each member state to appoint one or more national competent authorities responsible for enforcing the directive. There must also be effective mechanisms in place to promote sharing of information and cooperation among regulatory authorities.

Tougher penalties for non-compliance in NIS2

Under the NIS2 directive, there are tougher penalties for not following the rules. The enhanced requirements will have a big impact on how organizations handle security. The sanctions and fines for not following NIS2 will be stricter. These changes aim to make cybersecurity stronger and make sure organizations protect their networks and information systems. Organizations will need to have strong security measures and ways to report if they're following the rules.

If they don't, they might have to pay big fines. NIS2 is stricter than before, showing how important cybersecurity is in today's digital world.

Prepare for the Transition from NIS 1 to NIS2

Checklist for organizations affected by NIS2

NIS2 expands the scope of the original NIS directive. It now includes cloud infrastructure, internet exchanges, and domain name system service providers within its rules. NIS2 also requires more stringent security measures from digital service providers of all sizes. It establishes clear deadlines for compliance. Organizations in the Member States have until August 2023 to ensure full compliance.

To promote a culture of security, affected organizations should establish comprehensive security policies. They should also conduct regular security assessments and provide adequate training for their employees. Moreover, they should implement robust security measures like encryption, multi-factor authentication, and continuous monitoring. These measures will safeguard their infrastructure and customer data against cyber threats.

Deadlines for compliance with NIS2

Introduced in 2016, the original NIS directive set standards for UK organizations to protect essential services from cyber threats. NIS2, reflecting changes in the digital landscape, expands the directive to cover more digital service providers and introduces new compliance deadlines.

NIS2's compliance deadlines vary depending on the type of organization. For instance, operators of essential services must comply within 18 months, while digital service providers have 24 months. In contrast, the original NIS directive had a uniform deadline of 21 months for all organizations.

These differing deadlines show the increasing importance of cybersecurity in the UK and recognize the varying levels of digital infrastructure and services across organizations.

Proactive approach to meet NIS2 requirements

Organizations can improve their security by conducting regular cybersecurity risk assessments and monitoring threat intelligence. This helps in identifying and addressing potential vulnerabilities, staying ahead of security threats, and complying with NIS2 regulations.
