A proven method to master your cyber risks
Our support follows a structured 6-step approach, grounded in leading frameworks (ISO 27001, EBIOS Risk Manager, NIST, CIS) and over 10 years of field experience across SMBs and large enterprises.
In short: NagaShield Security applies a 6-step approach — (1) scoping, (2) audit, (3) EBIOS Risk Manager risk analysis, (4) prioritised treatment plan, (5) implementation and support, (6) monitoring and continuous improvement (PDCA). The goal: security proportionate to real risk, aligned with ISO 27001 and the NIS2 directive.
