- Integration – Integrate VPNs with routing protocols (OSPF, BGP) and identity platforms (RADIUS, LDAP, SAML).

- Advanced Troubleshooting & Escalation – Serve as the L3 escalation point for VPN‑related incidents, performing packet‑level diagnostics and root cause analysis.

- Documentation & Compliance – Maintain detailed design documents, runbooks, and change records to support audits and compliance frameworks (ISO 27001, NIST, PCI‑DSS).
