ThingsBoard vs OpenCTI: at a glance
What is ThingsBoard?
An IoT platform whose release notes have become a CVE ledger
ThingsBoard ships every release twice — once on the 4.3 line and once as a 4.2 backport with an identical security section — and those security sections now dominate the notes, running to twenty or thirty CVEs per release. The recurring classes are telling: SSRF through AI model provider URLs, SSRF and file access escapes from the TBEL script sandbox, DNS rebinding bypasses, and access control on alarm comments. Feature work continues underneath, mostly IoT Hub integration and an Angular 20 UI migration.
What is OpenCTI?
OpenCTI is turning its connector catalog into a marketplace with a support tier attached.
OpenCTI ships on a roughly weekly cadence, and the last six releases mix steady platform work — saved searches, dashboard filters, workflow governance — with a consistent push on how connectors are discovered and supported. The catalog became a faceted marketplace in late July, connectors are now labelled as supported by Filigran or by the community, and several releases wire the platform into Filigran's XTM Hub. The notes themselves are dense PR lists with no narrative, so the direction has to be read off what keeps recurring.

An IoT platform whose release notes have become a CVE ledger
◆ Current state
ThingsBoard ships every release twice — once on the 4.3 line and once as a 4.2 backport with an identical security section — and those security sections now dominate the notes, running to twenty or thirty CVEs per release. The recurring classes are telling: SSRF through AI model provider URLs, SSRF and file access escapes from the TBEL script sandbox, DNS rebinding bypasses, and access control on alarm comments. Feature work continues underneath, mostly IoT Hub integration and an Angular 20 UI migration.
◆ Where it's heading
The platform is paying down the security cost of being extensible. TBEL scripting and user-configurable AI model endpoints are exactly the features that make ThingsBoard useful for industrial rule engines, and both are repeatedly the source of sandbox and SSRF findings — so the work has shifted to fencing them with allow-lists, opt-in SSRF protection and configurable security headers. Meanwhile the AI surface keeps growing, with structured output support spreading across more model providers.
◆ Prediction
The dual-branch pattern will hold, with 4.2 continuing to receive the same security sets as 4.3 until it reaches end of life; expect further hardening of the TBEL sandbox rather than new scripting capability.
OpenCTI

OpenCTI is turning its connector catalog into a marketplace with a support tier attached.
◆ Current state
OpenCTI ships on a roughly weekly cadence, and the last six releases mix steady platform work — saved searches, dashboard filters, workflow governance — with a consistent push on how connectors are discovered and supported. The catalog became a faceted marketplace in late July, connectors are now labelled as supported by Filigran or by the community, and several releases wire the platform into Filigran's XTM Hub. The notes themselves are dense PR lists with no narrative, so the direction has to be read off what keeps recurring.
◆ Where it's heading
The recurring thread is commercial structure around an open-source core. Enterprise Edition gating on workflow restrictions, a catalog that distinguishes vendor-supported connectors from community ones, and repeated XTM Hub integration all point the same way: the platform stays open while the ecosystem and its support tiers become the thing being sold. Underneath that, the workflow subsystem keeps maturing through draft approval, auto-save, reset and restore, which suggests adoption by teams that need review gates before intelligence is published.
◆ Prediction
Expect more of the catalog to organize around the supported-versus-community distinction, and the draft approval workflow to pick up the permission and audit controls that the recent RBAC and audit-log work is laying groundwork for.
