A group of operational technology cybersecurity vendors launches ETHOS, an open-source portal for sharing early warnings about critical infrastructure threats

Context & Ripple Effects
ETHOS extends a decade-long drift from proprietary threat feeds toward shared infrastructure. The Open Cybersecurity Alliance's OpenDXL Ontology in 2020 tried to give security tools a common language, and the Open Cybersecurity Schema Framework later pulled AWS, Splunk, IBM, CrowdStrike, Cloudflare, and Okta into standardizing detection data. Those efforts lived in enterprise IT; ETHOS carries the same open-sharing model into operational technology, where the vendors involved sell to critical-infrastructure operators.
The launch also lands amid a broader loosening of threat-sharing norms: [[a:1169164|Anthropic began letting Mythos users responsibly share cybersecurity threats with others facing similar vulnerabilities]], a sign that even AI vendors are treating threat intel as something to be circulated rather than hoarded. For OT vendors, the question is whether an open portal becomes the default early-warning channel for critical infrastructure.
First-order effects
- Critical-infrastructure operators gain a free, vendor-neutral early-warning channel for OT threats, while the launching vendors commit to pooling intel they previously held as a competitive asset.
Second-order effects
- Vendors outside the group face pressure to contribute to ETHOS rather than run closed OT threat feeds, since an open portal sets the reference point customers will compare paid intelligence against.
Third-order effects
- If the pattern holds across OpenDXL, OCSF, Athena, and now ETHOS, threat intelligence becomes a shared commons in both IT and OT, pushing vendor differentiation up the stack toward response tooling and integration rather than exclusive data.
The trend: Cybersecurity threat intelligence is consolidating around open, vendor-neutral sharing infrastructure, with operational technology and critical infrastructure as the newest frontier.
