What does an RSSI/CISO do?

The RSSI steers information security, without necessarily implementing it personally. They define the strategy and the security policy, manage the risk management, oversee compliance, coordinate incident response and drive awareness across teams.

It is a role of orchestration and arbitration: translating business challenges into security requirements, and security constraints into decisions that management can understand. It often relies on a SMSI to structure its work.

Its main responsibilities

Strategy & governance

Define the security trajectory, policy and indicators; report to management.

Risk management

Map and prioritize risks, track the treatment plan and residual risk.

Compliance

Ensure compliance with requirements (ISO 27001, NIS2, RGPD…) and prepare audits.

Incident preparedness

Anticipate and coordinate incident response and business continuity.

Awareness & security culture

Upskill teams so security becomes a shared reflex, not a constraint.

Monitoring & benchmarking

Track evolving threats and frameworks to maintain an up-to-date security posture.

Do you need a full-time RSSI/CISO?

Every organization needs the RSSI/CISO function; few need (or can afford) a full-time position. For SMEs and mid-sized companies, an outsourced or fractional RSSI/CISO provides the right level of expertise and management, without the cost of a dedicated hire. This is precisely the purpose of our offer external RSSI/CISO.

A translator role

The real value of an RSSI/CISO lies in their ability to bridge the gap between worlds that rarely speak the same language: management (stakes, budget), business teams (uses, constraints), technical teams (measures) and legal (compliance). A good RSSI/CISO does not simply say “no”: they propose informed trade-offs, document accepted risk and bring teams on board. It is as much a governance role as a technical one.
