What is the primary objective of **NIS2**?

**The primary objective of **NIS2** is to establish a high common level of cybersecurity and resilience across EU member states by strengthening risk management, incident reporting, and governance for critical infrastructure and digital services.** It expands upon the original NIS Directive, imposing obligations on **essential entities** (typically 250+ employees, €50M+ turnover, or €43M+ balance sheet) and **important entities** (50+ employees, €10M+ turnover, or €10M+ balance sheet) in sectors like energy, transport, health, and digital infrastructure including cloud computing.

Who is legally or professionally required to comply with **NIS2**?

**NIS2 applies to all medium-sized and large **essential** and **important entities** operating in specified high-criticality sectors within the EU, under a size-cap rule.** This includes entities with 50+ employees or €10M+ annual turnover in sectors such as energy (electricity, oil, gas, district heating), transport, public administration, waste management, food production, postal services, manufacturing, and digital providers like cloud computing and online marketplaces. Criticality can override size thresholds if an entity is a sole provider of essential services.

Does **NIS2** require an external audit or third-party certification?

**NIS2 does not mandate external audits or third-party certification but empowers national authorities to conduct live spot checks and demand real-time evidence of compliance.** Organizations must maintain continuous, auditable records of risk management, incident response, supply chain security, and business continuity measures, shifting from static compliance to evidence-based assurance.

How often should an assessment for **NIS2** be performed?

**NIS2 requires ongoing, continuous risk assessments rather than fixed intervals, with dynamic updates such as quarterly risk registers and asset inventories.** Entities must implement proactive risk management, including regular vulnerability identification, supply chain reviews, and closed-loop improvements to ensure resilience against evolving threats.

What are the consequences of non-compliance with **NIS2**?

**Non-compliance with NIS2 incurs tiered fines up to €10 million or 2% of total global annual turnover for **essential entities**, and up to €7 million or 1.4% for **important entities**, plus potential business suspension and senior management liability.** National authorities enforce via spot checks, with transposition into national laws effective from October 18, 2024.

Can **NIS2** be mapped to other international frameworks?

**Yes, EU member states incorporate standards like **ISO 27001** and **NIST CSF** into national NIS2 frameworks to facilitate compliance mapping.** Organizations can leverage these for risk management, incident handling, and supply chain security, though national variations apply post-transposition.

What is the first step to begin implementing **NIS2**?

**The first step for NIS2 implementation is to determine applicability by assessing entity size, sector, and operations against the size-cap rule and criticality criteria.** Register with national authorities, providing details like organization name, contacts, sector, and service locations across member states, ahead of the October 18, 2024, enforcement date.

What is the primary objective of **CSL (Cyber Security Law of China)**?

**The primary objective of CSL is to establish a nationwide statutory framework governing network security, data localization, and cybersecurity governance for all entities processing data in China.** Enacted on **June 1, 2017**, with 69 articles, it mandates technical safeguards like firewalls and SOC monitoring (**network security**), storage of **Critical Information Infrastructure (CII)** and **important data** in Mainland China (**data localization & PIP**), and executive accountability with incident reporting (**cybersecurity governance**).

Who is legally or professionally required to comply with **CSL (Cyber Security Law of China)**?

**All network operators, CII operators, data processors of important data, and foreign enterprises serving Chinese users must comply with CSL.** This includes entities owning networks for public services (e.g., **Tencent Cloud**), operating systems critical to national security or economy (e.g., power grids), handling large-scale personal or **important data** (e.g., e-commerce platforms), and foreign services like **Microsoft 365** touching Chinese users.

Does **CSL (Cyber Security Law of China)** require an external audit or third-party certification?

**CSL requires government-approved security evaluations and certifications for CII operators, including third-party Security Protection Capability Test (SPCT) reports submitted to MIIT.** **Article 20** mandates penetration testing and vulnerability scanning; CII entities must obtain **China Information Security Certification (CISC)** via certified agencies, with ongoing assessments ensuring compliance.

How often should an assessment for **CSL (Cyber Security Law of China)** be performed?

**CSL assessments must be conducted periodically, with annual compliance reporting and reassessments within 60 days of regulatory amendments.** **Article 20** requires ongoing security testing for CII assets; incident-response validation and continuous monitoring via KPIs (e.g., Mean Time to Detect) ensure real-time adherence, supplemented by quarterly training and internal audits.

What are the consequences of non-compliance with **CSL (Cyber Security Law of China)**?

**Non-compliance with CSL incurs fines up to 5% of annual revenue, business license suspension, service shutdowns, and operational disruptions.** The 2022 amendment escalates penalties; examples include a CNY 150 million fine for data non-localization and API blocks for cloud providers, plus reputational damage and lawsuits under intersecting laws.

Can **CSL (Cyber Security Law of China)** be mapped to other international frameworks?

**Yes, CSL can be mapped to international frameworks like ISO 27001 and NIST for aligned controls.** Its policy suite, governance (e.g., **Article 21** responsibilities), and technical measures (e.g., Zero-Trust, SIEM) integrate with Annex A controls, enabling audit readiness and hybrid implementations for global operations.

What is the first step to begin implementing **CSL (Cyber Security Law of China)**?

**The first step is Phase 0 pre-engagement: secure executive sponsorship and conduct regulatory baseline mapping.** Establish a C-suite charter, cross-functional steering committee, and catalog of applicable **CSL articles**, followed by comprehensive asset inventory and gap analysis using tools like Qualys for CII and important data classification.
