// What we deliver

Solutions built on hands-on operational depth.

Every engagement is led by the same engineer who administers the tenants, reads the packet captures, and owns the Sev 1 tickets — not a hand-off between sales and delivery.

Zero Trust & SASE Architecture

Design and deployment of ZTNA/SASE environments across Zscaler ZIA, ZPA, and ZDX, aligned to Zero Trust principles from the ground up.

SD-WAN & Traffic Engineering

Resilient traffic-forwarding designs, PAC-file strategy, GRE/IPsec tunneling, and Z-Tunnel configuration for distributed, hybrid networks.

OT/ICS & Industrial Security

Purdue-model network design, segmentation, and hardening for offshore and onshore industrial sites, refineries, and process-control environments.

Incident Response & RCA

Ownership of security incidents from triage to root-cause resolution, using PCAP analysis, ZDX hop-by-hop diagnostics, and SAML/MFA flow tracing.

Secure AI Adoption

AI application discovery, access governance, and GenAI data-protection guardrails using Zscaler AI Security and NIST AI RMF principles.

Tenant Administration

Day-to-day operation and policy tuning of ZIA/ZPA/ZDX tenants, URL filtering, Cloud Firewall, App Segments, and Client Forwarding Profiles.

// How we engage

A repeatable path from requirements to stable operations.

01

Assess

Network and security assessment: traffic analysis, firewall-rule review, and compliance alignment against your current posture.

02

Architect

Solution design covering forwarding, segmentation, identity integration, and Zero Trust policy — documented, not improvised.

03

Deploy

Staged rollout with FAT/SAT-style test procedures, PAC-file and policy migration, and stakeholder sign-off at each stage.

04

Operate

Ongoing tenant health, incident response, and enhancement backlog work — the same engineer who designed it keeps it running.

// Led by

A principal engineer, not a delivery layer.
