We are seeking a Senior Technical Consultant to lead firewall, network access control, and SASE engagements across diverse enterprise environments. This role spans three core technology pillars: next-generation firewall design and deployment (Cisco Secure Firewall, Palo Alto Networks), Cisco ISE-based network access control and identity services, and SASE/Zero Trust architectures (Zscaler, Palo Alto Prisma Access, Cisco Secure Access, Netskope). The ideal candidate combines deep hands-on expertise across these platforms with strong consulting skills, owning end-to-end delivery from discovery and design through implementation, testing, and knowledge transfer. This is a client-facing role that requires the ability to lead technical workstreams, produce professional documentation, and communicate complex security strategies to both technical and executive audiences.
Key Responsibilities
Key Responsibilities -- Firewall
Design and deploy Cisco Secure Firewall Threat Defense (FTD) managed by Firewall Management Center (FMC), including high-availability pairs, threat policies (Snort IPS, malware defense, URL filtering), and both site-to-site and remote access VPN configurations.
Configure and manage Palo Alto Networks next-generation firewalls running PAN-OS, including security profiles (Antivirus, Anti-Spyware, Vulnerability Protection, WildFire), App-ID, User-ID, SSL/TLS decryption, and centralized management via Panorama.
Lead firewall migration projects including legacy Cisco ASA to FTD conversions, cross-vendor migrations (Check Point, Fortinet, Juniper to Palo Alto or Cisco), and policy translation with rule optimization during cutover.
Design network segmentation architectures using firewall zones, virtual routers, VRFs, and policy-based routing to enforce least-privilege east-west and north-south traffic controls.
Deploy cloud-native firewall solutions including Palo Alto Cloud NGFW for AWS and Azure, and Cisco Secure Firewall Cloud Native for containerized and cloud workload environments.
Implement firewall high availability designs including active/standby failover, active/active clustering, and multi-context deployments for service provider and large enterprise environments.
Configure centralized logging, SIEM integration (Splunk, Microsoft Sentinel, syslog), and NetFlow/IPFIX for traffic analytics, threat correlation, and compliance reporting.
Perform firewall rule base optimization, policy cleanup, and compliance auditing to reduce attack surface and align with regulatory frameworks (PCI-DSS, HIPAA, NIST).
Integrate Cisco Secure Firewall with Cisco XDR for cross-platform threat detection, event correlation, and automated incident response across the security portfolio.
Automate firewall provisioning, configuration backup, and policy deployment using infrastructure-as-code tools (Terraform, Ansible) and vendor APIs for repeatable, auditable workflows.
Key Responsibilities -- Cisco ISE
Deploy Cisco Identity Services Engine (ISE) for 802.1X wired and wireless authentication, MAC Authentication Bypass (MAB), and RADIUS/TACACS+ device administration across campus, branch, and data center environments.
Design and implement ISE authorization policies including Security Group Tags (SGTs) with TrustSec, downloadable ACLs (dACLs), VLAN assignment, and Adaptive Network Control (ANC) for dynamic threat response.
Configure ISE profiling services, posture assessment, and compliance enforcement to provide endpoint visibility and ensure devices meet organizational security baselines before granting access.
Integrate ISE with Cisco network infrastructure (Catalyst switches, wireless LAN controllers, Secure Firewall) and third-party network access devices for consistent policy enforcement across heterogeneous environments.
Deploy ISE guest portals, BYOD onboarding workflows, and certificate-based authentication (EAP-TLS) with internal or external certificate authorities for secure device enrollment.
Implement pxGrid integrations to share identity and session context between ISE, Cisco Secure Firewall, Splunk, and third-party security platforms for unified policy enforcement and threat intelligence.
Design ISE distributed deployments spanning Policy Administration Nodes (PAN), Policy Service Nodes (PSN), and Monitoring and Troubleshooting Nodes (MnT) for scale, redundancy, and geographic distribution.
Perform ISE upgrades, migrations (legacy ACS to ISE), and advanced troubleshooting using RADIUS live logs, policy trace, TCP dump, and debug utilities to resolve authentication and authorization issues.
Key Responsibilities -- SASE / Zero Trust
Design and implement SASE and Zero Trust architectures covering remote user, branch office, cloud workload, and data center connectivity use cases with a unified security policy framework.
Configure and deploy Zscaler Internet Access (ZIA) including Secure Web Gateway, SSL inspection, URL filtering, cloud firewall, and sandbox policies, and Zscaler Private Access (ZPA) including ZTNA application segments, App Connectors, and browser-based access.
Deploy Palo Alto Prisma Access including GlobalProtect remote user connectivity, explicit proxy for branch offices, and service connections to on-premises infrastructure managed through Strata Cloud Manager or Panorama.
Implement Cisco Secure Access (SSE) including Zero Trust Network Access, Secure Web Gateway, Cloud Access Security Broker, and resource connector deployment for private application access.
Configure Netskope Security Cloud including Next Gen SWG, CASB with API-enabled and inline protections, and Netskope Private Access (NPA) with traffic steering, real-time protection policies, and DLP controls.
Leverage Guardicore microsegmentation for east-west traffic control, application ring-fencing, and workload visibility to complement SASE north-south protections in hybrid and multi-cloud environments.
Deploy identity-based access controls integrating with Okta, Microsoft Entra ID, SAML 2.0, and SCIM provisioning to enforce user and device trust across all SASE platforms.
Develop and maintain Zero Trust maturity roadmaps for clients, mapping current-state gaps to phased adoption plans across identity, device, network, application, and data pillars.
Architecture, Delivery, and Documentation
Lead client-facing discovery sessions, design workshops, and architecture reviews to define firewall, NAC, and SASE strategies aligned with business objectives and compliance requirements.
Own the creation of High-Level Design (HLD) and Low-Level Design (LLD) documents, network diagrams, implementation runbooks, and as-built documentation for firewall, ISE, and SASE deployments.
Develop migration and cutover plans with rollback procedures, change management workflows, and CAB review packages
Conduct knowledge transfer sessions and train client operations teams on day-2 firewall management, ISE policy administration, SASE platform operations, and incident response procedures.
Manage project workstreams, track milestones and deliverables, and escalate risks proactively to project and account leadership
Serve as the technical escalation point for junior engineers during engagements, conducting reviews of policy configurations and providing mentorship
Contribute to internal practice development including reusable templates, deployment runbooks, and automation playbooks for firewall, ISE, and SASE engagements.
