Over de functie
As Information Security Officer (Third-Party Risk Management) you are responsible for managing and strengthening PostNL's security posture across suppliers and customer-facing partnerships. You combine cybersecurity expertise with stakeholder management skills, ensuring that third-party risks are identified, assessed and mitigated in a structured and pragmatic way. You assess security risks within supplier landscapes, evaluate compliance with PostNL security standards and relevant legislation (e.g. NIS2, GDPR), and advise internal stakeholders on required risk treatment measures. You act as a key partner for procurement, legal, vendor management and IT teams, ensuring that security is embedded in onboarding, contracting and lifecycle management of third parties.
Verantwoordelijkheden
- Strategic impact: Third-party risk is high on the board agenda. Your work directly contributes to resilience and compliance.
- Complex stakeholder landscape: You operate at the intersection of IT, business, legal and suppliers.
- Maturity growth: You contribute to further professionalizing TRPM within a large, regulated organization.
- Visibility: You interact with senior management and external strategic partners.
- Development: Opportunity to deepen expertise in regulatory frameworks (NIS2, DORA-like principles, supply chain security).
Wat ga je doen
Within the Cyber Security Office (CSO), you are part of the Suppliers & Customers domain. This domain focuses on managing cyber risks that arise from external parties and strategic partnerships.

- Perform third-party security risk assessments (due diligence, onboarding and periodic reassessments).
- Evaluate supplier compliance against ISO27001, NIST CSF and PostNL internal policies.

- Advise on contractual security clauses and minimum control requirements.
