cyberzero is a security-first technology company focused on protecting critical systems and long-lived data in complex environments.
Our work spans security architecture, cloud hardening, Zero Trust design, API security and cryptographic analysis. We also operate at the leading edge of post-quantum cryptography and cryptographic lifecycle risk, helping organizations understand where cryptography exists, how it is used, and how it ages over time.
We operate vendor-agnostically and prioritize correctness, confidentiality, and operational reality over tooling or checklists.

• Solid understanding of secure coding practices, trust boundaries, and data handling
