Deploy and configure Tofino industrial firewalls to protect SCADA systems and PLCs using deep packet inspection for OT protocols including Modbus, EtherNet/IP, OPC, and S7comm, enforcing granular access control between ICS security zones.

Maps and reproduces OAuth/OIDC authentication chains by tracing redirects, token exchange, and identity acceptance in controlled environments.

Performs security scanning, compliance checks, deployment planning, and infrastructure setup, with optional dependency auditing and bundle size analysis.

Manage and inspect OPA policies, Gatekeeper constraints, and Rego rules, including discovery, testing, and audit analysis.

Perform vulnerability scanning in OT/ICS environments safely using passive monitoring, native protocol queries, and carefully controlled active scanning with Tenable OT Security to identify vulnerabilities without disrupting industrial processes or crashing legacy controllers.

Conduct comprehensive security assessments of Operational Technology (OT) networks including SCADA systems, DCS architectures, and industrial control system communication paths, addressing the Purdue Reference Model layers and identifying IT/OT convergence risks.

Monitors Modbus TCP traffic on SCADA and ICS networks to detect anomalous function code usage, unauthorized register writes, and suspicious communication patterns using deep packet inspection with pymodbus, Scapy, and Zeek.

Authorized OT/ICS security assessment covering Purdue model zoning, PLC/SCADA exposure, industrial protocol discovery, and safe passive-first evaluation.

Audits CircleCI orb versions and configurations using the CircleCI v2 API, flags deprecated orbs, provides pinning recommendations, and checks security advisories from the orb registry.
