Cybersecurity for large enterprises
Stakes that match your exposure
Large enterprises, CAC 40 / SBF 120 listed groups, Operators of Essential Services (OES): a broad attack surface, demanding regulatory requirements, and incident impacts that can be systemic.
DORA & sector obligations
Your sector obligations (finance, insurance, critical infrastructure): DORA, NIS2, IEC 62443, PCI-DSS, HDS, SecNumCloud. Testing and operational resilience requirements with imposed deadlines.
Multi-site complexity
Subsidiaries, partners, multi-provider cloud, converged OT/IT: risk mapping and policy consistency require specialist expertise and a global view.
ANSSI qualification requirements
PASSI RGS audits across all 4 scopes (organisational & physical, architecture, configuration, penetration testing), a common requirement in regulated tenders and for Operators of Essential Services (OES) under NIS2.
Our value to large organisations
Complex PASSI audits
Large-scale penetration testing (red team, purple team), multi-scope security audits across heterogeneous perimeters. Reports compliant with regulatory requirements.
ISO 27001 / DORA compliance programme
Programme management for certification or compliance across multiple entities. ISMS governance, vendor steering, preparation for third-party audits.
Managed SOC & threat intelligence
Extended monitoring of your perimeter, integration with your in-house SOC teams, targeted threat intelligence (BrightCTI) and planned crisis exercises.
Security architecture & Zero Trust
Review and design of reference architectures. Zero Trust strategy, IAM, segmentation, PKI, remote access security. Cloud (Azure, AWS, GCP) and hybrid expertise.
