- Design and configure multi-vendor firewall architectures, including:
- Palo Alto Networks NGFW
- Zscaler SASE
- Check Point
- Cisco NGFW / Firepower
- Fortinet and Juniper platforms
- Implement secure connectivity:
- IPSEC tunnels, SSL VPN
- Routing, filtering, and segmentation policies
- Support:
- Identity integration (Active Directory, SAML)
- Secure application access controls
5. Security Operations & Staff Augmentation Support
- Provide hands-on operational support and consulting, including:
- SAML-based authentication integrations
- Proxy Auto-Configuration (PAC) file development
- Application segmentation and policy tuning
- Support security operations teams with:
- Incident triage enhancements
- Platform troubleshooting and performance tuning
Required Skills & Experience Core Technical Skills
