Why Z-CMS
Built by experts. Trusted by industry.
Z-CMS is not a generic compliance tool — it was purpose-built for IoT cybersecurity regulations by one who contributed to the drafting of EN 18031.
Expert-Built Methodology
Every Q&A, guidance note and interpretation in Z-CMS was authored by Dr. Guillaume Dupont — a contributor to EN 18031 with 10+ years of IoT cybersecurity expertise.
10+ years of IoT cybersecurity & compliance expertise
Step-by-Step Guided Q&A
No need to read 600 pages of standards yourself. Z-CMS breaks every requirement into intelligent questions with built-in guidance, so your team stays on track.
From 12 months to 1–2 months of project duration
Trusted by Notified Bodies
Technical documentation generated by Z-CMS has been accepted by Notified Bodies without modification — giving you confidence before you even submit.
"Our Notified Body accepted everything exactly as sumitted"
On-Premises Security
Z-CMS runs inside your network and firewalls. Your compliance data never leaves your environment — no SaaS analytics, no AI training, no Zealience access.
Your data stays yours. Always.
The hard truth
Manual compliance is painful,
slow, and expensive.
Without the right tooling, cybersecurity compliance becomes an engineering bottleneck. Here's what teams face when they try to do it alone.
A single compliance project done manually can consume an entire year of engineering time — before a single product ships.
Between internal engineering hours and external consultants, first-time compliance easily exceeds six figures — for a single product family.
Every requirement demands its own Decision Tree, manually filled, justified, and maintained. One mistake cascades through the entire file.
European cybersecurity standards are overwhelming in volume—EN 18031 alone exceeds 600 pages, with CRA texts adding hundreds more. No team can fully grasp it all.
The standards require manufacturers to identify their product's assets — but provide little guidance on how. Most teams get this wrong on the first attempt.
You cannot identify which requirements apply until you've mapped all your assets and interfaces. The process is inherently iterative — and without the right tooling, every iteration costs weeks.
Z-CMS makes RED DA compliance much less daunting and frustrating. We created our first technical file manually before purchasing the tool, but we discarded it and started over once we understood Z-CMS's capabilities.
— P. McGrotty, Embedded System Architect at XirgoWhat Z-CMS delivers
Compliance results, not compliance headaches.
Z-CMS automates the hardest parts of cybersecurity compliance — so your team can focus on building great products.
Never touch Excel again.
Z-CMS captures your product information through intelligent Q&As — built on algorithms that adapt the question flow based on your answers. With over a million possible paths, every product is handled with precision. The result: properly structured compliance data, generated automatically.
Up to 70% reduction in typing compared to manual documentation.
Stop guessing what your assets are.
Standards assume manufacturers already know what "assets" their product has — a concept most engineers have never encountered. Z-CMS guides your team through an iterative discovery process: "Do you have a network communication protocol implementation on this interface?" You'll never be stuck wondering where to start.
Assets discovered step by step, with no compliance jargon left unexplained.
An expert by your side, at every step.
Dr. Guillaume Dupont's decade of IoT cybersecurity expertise is embedded throughout Z-CMS. Every ambiguous term is explained. Nearly every question has dedicated guidance on how to interpret and answer it. Your engineering team doesn't just get compliant — they get upskilled.
"Z-CMS has been a great resource for developing real cybersecurity expertise." — Ela Innovation
Know your compliance status at a glance.
Compliance completion percentage, RED DA Decision Tree results, CRA gap analysis — all aggregated in real-time dashboards. Stakeholders can act on non-compliance immediately, without waiting months for a third-party laboratory report.
No more waiting. No more surprises before submission.
Compliance is a team sport.
Create tasks, assign them to stakeholders, and track progress — all within Z-CMS. A dedicated task management view keeps your whole team aligned and accountable. Something that's simply not possible when compliance lives in a shared Excel file.
Replace scattered spreadsheets with structured team collaboration.
Two regulations. One platform.
