Everything you need to know about ISO, NIS2 and GDPR compliance
What is ISO 27001, NIS2, and GDPR compliance?
ISO 27001 is a voluntary information security management standard. NIS2 is a mandatory European directive imposing cybersecurity measures on critical sectors. The GDPR governs the protection of personal data. Together, they structure a company's security and digital trust.
Is my company affected by the NIS2 Directive?
NIS2 applies to medium or large entities (50 employees and/or €10 million turnover or balance sheet) active in a critical sector: energy, health, transport, finance, digital, water, public administration, etc. An audit can confirm your exact status.
What are the financial risks of non-compliance?
The GDPR provides for fines of up to €20 million or 4% of global annual turnover. NIS2 provides for up to €10 million or 2% for essential entities, and up to €7 million or 1.4% for important entities, with possible liability for directors.
How long does achieving compliance take?
The duration depends on the initial maturity of your organisation. A GVISION compliance audit enables the establishment of a realistic action plan, generally spread over several months, with clear priorities based on identified risks.
Is ISO 27001 certification mandatory?
ISO 27001 remains voluntary in most cases, but it is strongly recommended and may become a contractual or regulatory requirement, particularly for NIS2 essential entities required to demonstrate an equivalent level of security.
Will achieving compliance disrupt our business?
No. GVISION plans each stage to minimise operational impact. Compliance generally strengthens the security and reliability of your systems, with no significant interruption to your day-to-day business.
Does GVISION offer follow-up after compliance is achieved?
Yes. GVISION provides ongoing support: regulatory monitoring, security measure updates, recurring training and preparation for renewal audits, to maintain your compliance over the long term.
What's the difference between GDPR and NIS2?
The GDPR protects personal data, regardless of the sector. NIS2 targets the overall resilience of information systems in critical sectors, beyond personal data alone. A company may be subject to both regulations simultaneously.
