About Proximus NXT
Proximus NXT is the leading reference in the Benelux for Cyber Security. You will find yourself in an environment where security is not a sideline, but the core business. You will become part of a powerful ecosystem: a team of top experts, ranging from strategic profiles to operational experts, supported by an immensely broad security portfolio. With us, you are never alone.
Your role:
The strategic guide for our customers. As a customer-facing CISO, you are the strategic conscience and trusted advisor for our customers. You are not behind the controls yourself, but you help determine the course. You translate complex cyber threats into clear board-level language and help consider how cyber security can support our customers' business strategy. Whether it concerns a managed security service, a CISO or GRC-as-a-Service role, or consultancy: you ensure that our customers are supported as effectively as possible in a constantly evolving security landscape. The technical execution? For that, you seamlessly liaise with our specialized security teams and Managed Services.
What will you do?
Strategy & Roadmap
You develop and implement a cybersecurity policy that fits the customer's DNA.
You map out clear long-term roadmaps.
You translate abstract strategy into tactical action plans and guide the execution.
High-Level Governance
You are the sparring partner at C-level and participate in board meetings and risk committees.
You set up security governance (who does what, how do we report?) and ensure cohesion between security, privacy, and business continuity.
Risk Management & Compliance
You initiate risk analyses (IT, OT, IoT) and make risks understandable for management.
You guide customers through the landscape of laws and regulations (such as NIS2) and prepare them for audits and ISO certifications.
Management of Security Incidents & Services
In case of serious incidents, you maintain oversight and calm. You coordinate crisis communication while our operational teams close the breach.
You advise customers on the optimal deployment of (our) SOC and monitoring services, and other security services.
Impact & Communication
You increase security awareness within the organization and present clear reports on risks and maturity.
You are the face of security: the central contact person for all stakeholders.
Who are you?
You are a bridge-builder. You combine deep substantive knowledge with the diplomatic skills of a top consultant.
Background & Knowledge
Academic work and thinking level.
Expertise in GRC (Governance, Risk & Compliance) and frameworks such as ISO 27001, NIST, and CIS.
Strong knowledge of legislation (including NIS2, GDPR) and IT Service Management (ITIL).
Experience with ICT architectures is a must; knowledge of OT/ICS and IoT is a strong advantage.
Personality & Skills
Strategic thinker: You quickly understand organizations and immediately see where the vulnerabilities and opportunities lie.
Strong communicator: You speak the language of the board and the language of the engineer. You present persuasively and write clearly.
Diplomatic & Steadfast: You can handle resistance, dare to push back when necessary, and remain independent in your advice.
Connector: You enjoy collaborating with our sales, architects, and engineers to build the best solution for the customer.
Why choose this role at Proximus NXT?
Impact: You work for leading customers and have a direct influence on their resilience.
Support: You stand on the shoulders of a gigantic organization with deep technical expertise.
Growth: You continuously learn by collaborating with the best specialists in the market.
