Approach Cyber is a trusted cyber resilience partner supporting organisations across Belgium and Switzerland.

With more than 25 years of experience, over 100 experts, and ISO 27001 and ISO 27701 certifications, we help companies face an increasingly complex digital world where threats accelerate, regulations expand, and resilience becomes essential.

This allows us to continuously evolve our technologies based on real incidents and real operational experience, while integrating selected third‑party solutions when relevant, always under our governance.

By bringing together strategic advice, adaptive security technologies, and continuous operational defence, Approach Cyber delivers end-to-end cyber resilience and true digital peace of mind.

Who we are looking for

As an Application Security Consultant, you will integrate our Application Security services.

Together with our 15 experts, we develop, maintain, support and host Specialized Softwares. Our expertise is two‑fold:

• Proposing our expertise to clients’ development teams in securing their Software Development Life Cycle (SSDLC or Secured‑SDLC).
• Developing highly secured softwares (Security by design) based on customer’s requirements (e.g. itsme – authentication app) ;

In this frame, we are recruiting an Application Security Consultant who will play a key role in our application security services growth over the next years.

Your role

This means:

• Operationalise (technically) the concept of Security by Design/Default in its four components: the availability of applications and underlying systems, the integrity (non‑alteration) of data, the confidentiality (non‑disclosure) of data and processing, and finally the traceability of actions performed on the system.
• Give guidance on establishing a secure software development lifecycle (Secure‑SDLC / DevSecOps),
• Help development teams to integrate application security best practices (e.g. OWASP ASVS), and security tooling/processes in their development pipeline (SAST, DAST, SCA, CVE follow‑up, …),

• Assist architects in designing secure solution components, considering the client’s application and business context, and the technologies available on the market.
• Contribute to assess an existing SDLC (i.e., SAMM Assessment)
• Verify the application of security requirements, in particular security test scenarios. Ensure that tests are carried out before any production launch.
