Scope of Work

What the Engagement Covers

Gap Analysis & Roadmap

We review your development process and product design clause by clause against IEC 62443-4-1 / 4-2, then deliver a gap list, priorities and an actionable implementation schedule.

Secure Development Lifecycle (4-1)

Build the SDL that IEC 62443-4-1 requires — security requirements, threat modeling, secure design review, security testing, vulnerability handling and patch management — with procedures and records your developers can follow.

Component Security Requirements (4-2)

We interpret each IEC 62443-4-2 requirement for embedded devices, network devices, host devices and software applications at your target security level (SL), helping engineering decide on implementation and evidence before gaps surface during certification.

Certification Readiness & Evidence

We assemble the document package certification bodies expect, and can pair it with ICSCracker SVV testing to produce test evidence mapped to each requirement.

Training & Internal Audit

IEC 62443-4-1 / 4-2 training for R&D and QA staff, plus an internal audit mechanism so compliance capability stays with your team.
