Independent technical validation and audit services for automation systems — covering FAT witnessing, compliance verification, hardware and software audits, and technical due diligence.
Independent validation provides the assurance that internal teams and OEM-supplied testing cannot — an objective assessment that the system meets its specified requirements, is fit for purpose, and complies with the applicable standards.
Rebus Novus provides third-party validation and audit services across three primary contexts: project delivery validation (FAT witness, SAT support, loop check verification), compliance audit (IEC 62443, IEC 61511 functional safety, cybersecurity posture assessment), and technical due diligence for asset acquisitions or operational handover.
Our FAT witnessing service provides a documented, independent record of factory testing outcomes — protecting the client’s interests in multi-vendor supply chains and providing defensible evidence for regulatory or insurance purposes. We review test procedures, witness execution, document non-conformances, and provide a formal FAT report.
For compliance audits, we assess against the relevant standard, provide a gap analysis with severity ratings, and recommend a prioritised remediation roadmap. Our technical due diligence service is used by investors, developers, and operators to assess the condition, compliance, and operational risk of acquired or inherited automation systems.
Tell us your application and challenge — our engineering team will recommend the right approach, technology fit and a clear roadmap, no obligation.
