• Extensive hands‑on experience designing, implementing, operating and troubleshooting SASE/SSE capabilities across large, complex organisations, including: SWG and SSL/TLS inspectionCASB, ZTNA and DLPcloud firewall and RBI/enterprise browsers.
• Demonstrated experience leading technical design, PoC, build and enterprise rollout of SASE/SSE. This includes at least one large-scale Zscaler (ZIA/ZPA) or Netskope deployment, ideally across multiple vendor ecosystems.
