How we measure

We read the ICS Advisory Project database – an open, structured mirror of every CISA ICS-CERT advisory – and keep the vendors that matter to DACH industry.

Source: the ICS Advisory Project (github.com/icsadvprj, CC-licensed), which structures the advisories of the US agency CISA. CISA tracks globally; the advisories concern products used worldwide, including in Germany. No AI model, no keys.

All figures without guarantee. Data source: ICS Advisory Project (mirror of CISA ICS-CERT advisories, CC). The vendor selection is curated (industrial automation relevant to DACH) and not exhaustive. An advisory doesn't mean your plant is affected – check the respective original advisory. i6eal is not a security authority.

Frequently asked questions

What does the ICS/OT Vulnerability Index show?

How many new security advisories (ICS-CERT) exist for the automation vendors common in German factories – with severity, a vendor ranking, a monthly trend and the latest reports.

Where does the data come from?

From the ICS Advisory Project, an open structured database of all advisories from the US cybersecurity agency CISA (ICS-CERT). We filter to vendors relevant to DACH industry and refresh daily, as CISA publishes new advisories.

Does an advisory mean my plant is insecure?

Not necessarily. An advisory describes a reported flaw in a product. Whether your specific plant is affected depends on version, configuration and patch level – the original vendor/CISA advisory clarifies that.

Why does Siemens have so many advisories?

Large vendors with very broad, globally deployed portfolios (like Siemens) publish correspondingly more advisories. The absolute number is not a measure of “insecurity”.

Digitalisation that lasts.

Whether AI in production or connected OT: we bring new technology into operation securely.
