The missions of the outsourced CISO
8 strategic and operational missions at the heart of your organization's digital resilience.
A dedicated CISO who knows your IS and your risks
Your outsourced CISO works on shared time or as a reinforcement to your teams. An experienced cybersecurity expert, they steer the security roadmap, incidents and NIS 2 / DORA compliance with the same rigor as an in-house CISO.
Mission 01
Define the cyber strategy
Information Systems Security Policy (ISSP), user charter, three-year plan aligned with business and regulatory challenges.
Mission 02
Analyze risks
Asset mapping, threat identification, impact assessment using EBIOS RM and ISO 27005.
Mission 03
Deploy security measures
Firewalls, IAM, MFA, EDR, SIEM, encryption, backups, system hardening: selection, deployment, monitoring.
Mission 04
Manage incidents and crises
Incident Response Plan (IRP), crisis cell, ANSSI/supervisory authority notification, external communication, lessons learned.
Mission 05
Raise staff awareness
Cybersecurity e-learning modules, quizzes, awareness campaigns, certification of good cyber reflexes.
Mission 06
Steer the supply chain
Security assessment of ICT suppliers, contractual clauses, sub-processor audits (ISO 27001, SOC 2).
Mission 07
Conduct audits and pentests
ISO 27001/HDS/PCI-DSS audits, penetration tests, configuration reviews, remediation plans.
Mission 08
Report to management
KPI dashboards (MTTD, MTTR, coverage rate), quarterly executive report, board preparation.
The CISO, guarantor of digital resilience
The CISO is much more than a technician: they are a strategic pilot who translates business challenges into security requirements, and who arbitrates cyber investments based on the residual risk acceptable to the management.
