An external CISO for your ISMS

Kertos gives you an external information security officer (CISO): they support the ongoing development of your ISMS, advise your management, and prepare you for upcoming audits. And they work where your risks, measures, and evidence already live — in the Kertos platform.

<h2>An external CISO who already knows your ISMS</h2>

‍

Your external CISO has an up-to-date view of risks, measures, documents, and training status in the Kertos platform at any time. That removes the routine of gathering paperwork and re-explaining where things stand at every catch-up. Before the engagement starts, we introduce you to your external CISO, and you can of course request evidence of their qualifications.

Running and improving your ISMS

Audits and Reports

Ahead of an audit, your external CISO supports the preparation, reviews the relevant evidence, and points out visible gaps or open actions. After the audit, they help put the findings in context and derive suitable corrective action. On request, they accompany audits and are available for expert questions on the ISMS. For security incidents, they support the assessment and help derive sensible improvement measures. Your management receives a regular, concise overview of ISMS status, material risks, and what needs attention.

“Fast, straightforward, and seamlessly automated!”

It's incredible how effortlessly the Kertos team guided us through the complex ISO 27001 process. Fast, straightforward, and seamlessly automated! Compliance is no longer on our minds because Kertos takes care of everything.

“European compliance automation built for mid-market teams”

As a mid-market company, we don't have a large compliance team, and Kertos means we don't need to build one. It automated our GDPR workflows so thoroughly that work which used to take days now takes minutes, and in many cases doesn't need a compliance manager to touch it at all. Onboarding took an afternoon, including connecting our own homegrown software via API. And unlike the mass compliance providers, we get a European partner who understands our requirements firsthand.

FAQ

Frequently Asked Questions

Information about Kertos' compliance platform

How does an external CISO differ from a virtual CISO (vCISO)?

An external CISO is a named person. A specialist from the Kertos team takes on the information security officer role for you, supports your ISMS, and is available to your management as a point of contact. You know who you are working with, and you can request evidence of their qualifications.

A virtual CISO (vCISO) describes software- and AI-supported guidance without a permanently named person. At Kertos, KAIA, our AI assistant, supports these tasks: KAIA structures your measures, flags what needs attention, and helps you keep your ISMS documentation current.

In both cases, overall responsibility for information security stays with your management.

Which companies is an external CISO right for?

Companies that run an ISO 27001 ISMS and need the role reliably filled, but do not have the volume to justify a full-time hire. Typical triggers are an upcoming certification or recertification, security requirements in an enterprise deal, NIS2, or the departure of the internal contact who held the role.

What does the Kertos external CISO actually do?

They steer the information security process: reviewing scope and requirements, assessing the risk assessment, preparing and facilitating the management review, reviewing ISMS documentation, evaluating measure and training status, preparing and following up audits, assessing security incidents, and reporting to management. We define the exact scope together with you.

What stays with us?

Overall responsibility for information security, decisions on risk, approvals, and the operational implementation of measures stay with you. You appoint an internal contact, the information security coordinator, who organizes input and makes sure recommendations get addressed in your organization. Your external CISO sets the direction and checks whether the measures work.

Do ISO 27001 or NIS2 require an information security officer?

ISO 27001 requires that responsibilities for information security are assigned and communicated clearly. NIS2 obliges management to own and oversee risk management measures. In both cases, a named person for information security is the usual way to meet that requirement with evidence, and auditors and customers ask for it.

How does the collaboration with the external CISO work?

Remotely, through regular check-ins and ad-hoc coordination as needed. The substance follows the relevant milestones in the ISMS lifecycle: regular risk assessments, management reviews, and upcoming audits. Beyond that, your external CISO supports you as things come up, whether changes, security incidents, or questions from outside parties. The service requires your ISMS to be run in the Kertos platform with the ISO 27001 module.
