A confidential client is seeking a Cybersecurity Architect to support a large organisation operating in a complex and security-sensitive IT environment.

  • Strong technical knowledge of enterprise infrastructure, networks and cloud environments.
  • Hands-on experience designing and implementing security controls.
  • Solid understanding of network security, firewalls, VPNs, segmentation and secure communication protocols.
  • Knowledge of IAM, authentication, authorisation and privileged access management.
