- Define trust boundaries, security zones, traffic flows, and segmentation requirements.
- Implement and optimise microsegmentation technologies including Illumio, Cisco, ColorTokens, or similar platforms.
- Configure and maintain least-privilege security controls to reduce attack surface and lateral movement risks.
- Integrate segmentation platforms with firewalls, identity services, SIEM platforms, and broader security tooling.
- Troubleshoot network connectivity, routing, forwarding, and policy enforcement issues.
- Support Zero Trust Architecture initiatives and cybersecurity uplift programs.
- Conduct technical assessments, threat modelling, and security design reviews.
- Work closely with network engineering, cloud, infrastructure, and application teams to deliver secure outcomes.
- Provide technical guidance and SME expertise on microsegmentation and Zero Trust principles.
- Develop and maintain architecture diagrams, operational procedures, and technical documentation.
- Engage with technology vendors, stakeholders, and support teams to resolve complex technical challenges.
