About
A focused cybersecurity consultancy
Cipher01 LLC is a US-based entity headquartered in Sheridan, Wyoming, USA. We serve clients across the United States and internationally, providing penetration testing, vulnerability assessment, GRC and ISO 27001 consulting, virtual CISO leadership, incident response, and digital forensics.
What we do
We help organizations understand where they are genuinely exposed and what to do about it. That means goal-driven offensive testing that demonstrates real impact, governance work that holds up under audit, fractional security leadership for teams without a full-time CISO, and calm, structured support when an incident is underway. Where useful, we also provide the IT support and services that keep day-to-day operations steady alongside the security work.
How we work
Every engagement follows the same four phases — Discovery, Assessment, Testing, and Remediation Guidance. Scope determines the depth of each phase; the methodology stays consistent so results are comparable over time. We brief both engineers and leadership, and we re-test remediated items to confirm closure.
What matters to us
Risk-led
We scope around the outcomes that matter to your business and test against realistic threat scenarios, not a fixed template.
Actionable
Findings are risk-ranked with reproduction steps and specific remediation guidance your team can execute.
Discreet
Engagement data — reports, findings, and evidence — is handled as sensitive information with strict access controls.
Standards-aware
Our GRC work is aligned to ISO 27001 and maps cleanly to the frameworks auditors and insurers expect.
