Casey Cresswell
CISSP-certified Cyber Security Engineer — Privileged Access Management, Zero Trust, and accreditation-ready architectures for federal and defense CIS.
Overview
●
CISSP (ISC²), 2025
I work on cyber stuff.
I enjoy working on zero trust stuff.
I’m also developing a Retrieval-Augmented Generation (RAG) project aimed at AI-driven security analysis and evidence generation. Details and a live demo will be added once the project is ready for public release.
Focus Areas
- Designing and hardening Zero-Trust and Privileged Access Management architectures across hybrid-cloud and on-prem CIS environments.
- Producing accreditation evidence for FISMA Moderate/High and DoD DISA SRG IL4/IL5 systems.
- Leading enterprise vulnerability management and developing custom remediation strategies for complex findings.
- Using Infrastructure-as-Code (Terraform, Ansible, GitHub Actions) to make security controls repeatable and auditable.
