An OT security practice built from field work.
ByteLock combines hands-on assessment experience from refineries, oil fields and production facilities with a platform that keeps security and compliance records current between audits.
Why ByteLock exists.
Industrial operators face a growing set of security standards and regulations, often with lean teams and processes that cannot be interrupted. ByteLock makes that obligation manageable: assessments designed around plant operations, controls mapped cleanly across frameworks, and records that remain maintainable after the engagement closes.
- Operations first
- Security activities are planned around safety and production, never the reverse.
- Evidence over opinion
- Every finding is substantiated by the configuration, log or drawing that supports it.
- Standards as a tool
- IEC 62443 and related frameworks structure the work rather than generate paperwork.
- Plain reporting
- Reporting written for engineers and executives alike, with defined owners and next steps.
- Built to last
- Registers and trackers your team can sustain independently.
- Honest scope
- Every report states what was tested, what was excluded, and why.
What we deliver.
ByteLock delivers risk, vulnerability and gap assessments for industrial automation and control systems (IACS), aligned with ISA/IEC 62443, NIST, ISO/IEC 27001 and national regulatory frameworks.
Engagements extend to unified control registers, compliance tracking, OT reference architecture design, system hardening, penetration testing and backup and recovery validation, ensuring findings translate into sustainable, auditable remediation.
