ThingsBoard vs Axiom: 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 Axiom?
Axiom is rebuilding observability so an AI agent, not a human, can be the first user.
Axiom is a logs, traces and metrics platform that reached feature parity on the fundamentals earlier this year — metrics went generally available in March, dashboards got a full API, and Correlations tied the three data types together for investigations. The last two months have been spent thickening the console: collapsible dashboard sections, gauge elements, schema locking, Grafana as a query surface. Underneath that steady product work, a second track has been running the whole time, aimed at AI agents as operators rather than at humans.

ThingsBoard

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.
Axiom
6.3ANALYTICS
Axiom is rebuilding observability so an AI agent, not a human, can be the first user.
◆ Current state
Axiom is a logs, traces and metrics platform that reached feature parity on the fundamentals earlier this year — metrics went generally available in March, dashboards got a full API, and Correlations tied the three data types together for investigations. The last two months have been spent thickening the console: collapsible dashboard sections, gauge elements, schema locking, Grafana as a query surface. Underneath that steady product work, a second track has been running the whole time, aimed at AI agents as operators rather than at humans.
◆ Where it's heading
That second track is now the main story. Metrics shipped queryable by agents through MCP and a dedicated skill, monitor management moved into the agent surface alongside the Grafana work, and evaluations arrived as both a live-traffic scoring feature and an agent-authored skill. The August release takes it to the account layer: an agent can now create its own Axiom organization and have a human claim it afterwards. Axiom is systematically removing the assumption that a person is present at each step.
◆ Prediction
The remaining human-gated surfaces are billing, access control, and dataset provisioning, and agent-created orgs makes those the obvious next targets. Expect the skills catalogue to keep growing into a set of task-shaped agent entry points rather than a single MCP endpoint.
