What is the role of a Cybersecurity attorney ?
A cybersecurity lawyer leads incident response, notifies the CNIL within 72 hours (Article 33 GDPR), informs data subjects for high-risk breaches (Article 34) and prepares NIS 2 (Directive (EU) 2022/2555) and DORA (Regulation (EU) 2022/2554) compliance in force since 17 January 2025. Consult one as soon as the attack is detected.

Practical examples
Crisis management after a ransomware attack
An industrial SME was paralyzed by ransomware encrypting its production data. The legal response was coordinated: CNIL notification, criminal complaint, cyber insurance negotiation, and management of contractual obligations to clients.
NIS2 compliance for an essential services operator
An energy provider needed to comply with the NIS2 directive. A gap analysis was performed, security policies drafted, and the company supported in its notification obligations to ANSSI.

What is a cybersecurity and cybercrime attorney ?
A cyberattack is never just a technical problem. It can expose sensitive data, block an IS… and engage your legal liability. A cybersecurity attorney secures your systems legally, from design, during crisis, and after the incident, all the way to technology litigation against attackers or defaulting providers.
- ✓Secure your processing under GDPR
- ✓Govern your IT providers and critical contracts
- ✓Manage incidents: CNIL complaints, litigation
- ✓Prepare your company to respond quickly and effectively to attacks
Computer attacks (malware, phishing, ransomware).
A security incident can result in: IS blocking, loss, encryption, or exfiltration of sensitive data, confidential document publication threats. Possible legal consequences: GDPR liability, client or partner disputes, contract breach.
Personal data breach.
Compromising personal data (CRM, logs, health data, etc.) triggers: mandatory CNIL notification within a short timeframe, communication to affected individuals, complete documentation of corrective measures.
Digital counterfeiting and fraud.
Cybersecurity also involves preventing image and reputation diversions: fraudulent brand or site use, 'fake invoice' or 'CEO fraud' scams, traffic theft via similar domain names.

Our practice in digital criminal law enables us to file complaints with civil party constitution, support judicial investigations led by specialized units (OCLCTIC, BL2C, C3N — names subject to change following recent reorganisations of the services), and represent our clients before the criminal court to obtain conviction and full compensation for damages.

GDPR audit & compliance.
GDPR requires a high level of security for personal data processing.
- Cloud, SaaS, CRM tool verification
- Register, DPA, and internal policy compliance assessment
- Preparation for potential CNIL inspection
NIS2 compliance.
The NIS2 Directive (EU 2022/2555), which was to be transposed into national law before 17 October 2024, considerably broadens the scope of entities subject to cybersecurity obligations. Beyond the OIVs and OSEs already covered by NIS1, the directive integrates new sectors: manufacturing, waste management, postal services, food industry, chemicals, and digital services.
Affected entities must notify significant incidents to ANSSI within 24 hours (initial alert) then 72 hours (full notification). INFLUXIO assists companies in assessing their subjection to NIS2 and in legal compliance.
- Assessment of your organization's subjection
- Implementation of notification procedures
- Management liability for cybersecurity
- Adaptation of contracts with your IT providers
Training & regulatory compliance.
Most incidents originate from human error.
- Practical workshops on data subject rights management
- Template responses for CNIL complaints or rights exercise requests
- Review and activation of your internal policies (PSSI, IT charter…)
Which cybersecurity regulations apply in 2026 ?
Three layered regimes now coexist in the EU. The NIS 2 Directive (Directive 2022/2555, whose transposition deadline of 17 October 2024 was missed by France) extends mandatory security and incident-notification duties to thousands of essential and important entities across 18 sectors.
The DORA Regulation (2022/2554) applies since January 2025 to financial entities and their critical ICT third-party providers. The Cyber Resilience Act (Regulation 2024/2847) imposes security-by-design obligations on hardware and software vendors placing connected products on the EU market.
Our firm maps each client's perimeter, builds compliance roadmaps and coordinates with the ANSSI for certification or incident handling.
Incident response and 72-hour clocks.
Both NIS 2 and the GDPR (Article 33) impose tight notification deadlines: an early warning within 24 hours of awareness, an incident notification within 72 hours, and a final report within one month. Mishandling these clocks may multiply sanctions. INFLUXIO operates as breach-coach: legal triage, forensic coordination, regulator dialogue and litigation containment.
Contractual cybersecurity and liability allocation.
Critical clauses include security warranties, audit rights, sub-processor flow-down (DPA aligned with GDPR Article 28), incident cooperation, indemnification caps and insurance obligations. We negotiate these clauses for clients in SaaS, fintech, health-tech and industrial IoT contexts.
NIS 2, DORA and incident response strategy.
The NIS 2 Directive (EU 2022/2555), whose transposition deadline of 17 October 2024 was missed by France (transposition law adopted subsequently to the deadline), dramatically expands cybersecurity obligations: 18 sectors covered, ~15,000 essential and important entities in France, mandatory incident notification within 24 hours, and personal liability of management bodies.
The DORA Regulation (EU 2022/2554), applicable since 17 January 2025, imposes additional ICT risk management obligations on financial entities. Sanctions can reach €10 million or 2% of global turnover. Our firm helps organisations map their NIS 2 / DORA scope, draft governance policies, and prepare incident response playbooks compliant with ANSSI guidelines.
Incident response and crisis management.
When a cyberattack occurs, our 24/7 response team coordinates with ANSSI (CERT-FR), the CNIL (within the 72-hour GDPR notification window of Article 33), insurers, and forensic providers. We secure evidence, manage regulatory notifications and prepare for potential class actions or shareholder claims.
Ransomware and ransom payment legality.
Paying a ransom is not formally prohibited in France but is strongly discouraged by ANSSI. The LOPMI Law of 24 January 2023 conditions cyber-insurance reimbursement of ransoms on a criminal complaint filed within 72 hours. We advise on the legal, regulatory and reputational implications of every option.

FAQ
Frequently asked questions.
A cybersecurity attorney manages the legal response to cyberattacks (ransomware, phishing, data exfiltration), handles CNIL and ANSSI notifications, files criminal complaints for cyber offences (Article 323-1 French Criminal Code) and ensures NIS 2 and GDPR compliance in coordination with digital law matters.
A cyberattack can lead to major legal consequences: civil liability if third parties suffer damage, criminal liability for negligence, loss of trust from clients, partners, or investors. Without structured legal support, crisis management can worsen the impact.
The first hours are critical: identify the breach and affected data, notify the CNIL within 72 hours if necessary, inform affected individuals, document actions and corrective measures. INFLUXIO supports you at every step.
Legal prevention rests on three axes: robust internal procedures (authentication, SSI policies, awareness), specific contractual clauses in IT/cloud/SaaS relationships, and monitoring and response mechanisms for identity or domain name theft.
The NIS2 Directive (2022/2555) expands the scope of entities subject to cybersecurity obligations, requiring risk analysis, proportionate technical and organizational measures, notification of significant incidents to competent authorities (ANSSI in France), and management accountability for non-compliance.
Any personal data breach likely to create a risk to individuals' rights and freedoms must be notified to the CNIL within 72 hours of becoming aware of it (Article 33 of the GDPR). If this deadline cannot be met, the notification must include the reasons for the delay.
The NIS 2 directive, transposed into French law, extends cybersecurity obligations to essential and important entities. Key obligations include cyber governance at executive level, documented technical and organizational measures, notification of significant incidents to ANSSI within 24 hours, and regular audits. Penalties may reach €10M or 2% of worldwide turnover.
Paying the ransom is strongly discouraged by ANSSI and the authorities. It guarantees neither data restitution nor the absence of subsequent leaks and finances organized crime. French law does not formally prohibit payment, but the LOPMI law of 24 January 2023 conditions insurance coverage on filing a complaint within 72 hours.
Article 33 of the GDPR requires notification to the CNIL within 72 hours of becoming aware of the breach, where it is likely to result in a risk to the rights and freedoms of individuals. If the risk is high, the data subjects must also be informed (Article 34 GDPR).
