FAQ
Common questions
Is this just another newsletter?
No. It's an operational briefing written for people who work with control systems — not a content marketing email. Every story is filtered for OT/ICS relevance. If it doesn't apply to industrial environments, it doesn't go in.
How is it different from CISA ICS-CERT alerts?
CISA publishes raw advisories — no context, no priority signal, no "what to do about it". Control Signal reads CISA, NVD, vendor bulletins, and industry press, then tells you what matters today and why. It's the layer between the raw data and your working day.
How long does it take to read?
About 4 minutes. One top story with context, 3–5 quick hits, and an optional weekly spotlight. Written to read before your first meeting.
Is the free plan actually free?
Yes — the full daily brief, live dashboard, CVE alert feed, and standards tracker are all free forever. Pro adds vendor filtering scoped to your specific vendors, an asset register that maps CVEs to your actual hardware, and a weekly summary digest.
What sectors does it cover?
Oil & gas, water & wastewater, power & utilities, manufacturing, chemicals & pharma, and transport & rail — with particular depth on the vendors common across those environments.
