Calibre vs OpenCTI: at a glance
What is Calibre?
Calibre is tying every performance number back to the deploy that caused it.
The August release brings deployments into Real User Monitoring: deploy markers run along the bottom of charts, hovering one reveals the commit, author, and time, and clicking through opens the commit in source control, with each deployment compared against the previous. The same day, Synthetic metrics moved from one page at a time to median aggregates across all pages, segmented by test profile, deployment, and page — so a regression can be identified as site-wide or isolated. Before that: automatic measurement of soft navigations in single-page apps, a site-scan crawler that discovers and maintains the monitored page list on its own, self-service SAML SSO with SCIM on the Team plan, and an organisation-wide audit log that exports as NDJSON or streams to a SIEM over signed webhooks.
What is OpenCTI?
OpenCTI's weekly train now merges entities in the knowledge view and reads defanged IOCs.
Filigran ships an OpenCTI weekly build plus backports to two LTS lines (7.2603 and 7.2608). The 10-16 weekly lets analysts merge entities directly from the knowledge view, search defanged indicators globally, collapse the ATT&CK pattern matrix and trim empty sections from generated Fintel reports. Earlier weeklies added enrichment from investigations, chatbot quotas and manual security coverage.

Calibre is tying every performance number back to the deploy that caused it.
◆ Current state
The August release brings deployments into Real User Monitoring: deploy markers run along the bottom of charts, hovering one reveals the commit, author, and time, and clicking through opens the commit in source control, with each deployment compared against the previous. The same day, Synthetic metrics moved from one page at a time to median aggregates across all pages, segmented by test profile, deployment, and page — so a regression can be identified as site-wide or isolated. Before that: automatic measurement of soft navigations in single-page apps, a site-scan crawler that discovers and maintains the monitored page list on its own, self-service SAML SSO with SCIM on the Team plan, and an organisation-wide audit log that exports as NDJSON or streams to a SIEM over signed webhooks.
◆ Where it's heading
Calibre is closing the loop between a metric moving and someone knowing why. Deployment attribution supplies the cause, the all-pages segmentation supplies the scope, and soft-navigation measurement fills the blind spot that made SPA numbers untrustworthy in the first place. Running alongside that is a distinctly enterprise track — SSO, SCIM, and an audit log with SIEM streaming are procurement requirements, and putting SAML on the Team plan rather than reserving it for Company is a deliberate move down-market with them.
◆ Prediction
Expect deployment attribution to grow into alerting — a regression tied to a specific commit is the natural trigger for a notification, and the pieces are now all in place. How far the site-scan crawler is meant to replace manual page management is not yet clear from these entries.
OpenCTI
5.0ANALYTICS
OpenCTI's weekly train now merges entities in the knowledge view and reads defanged IOCs.
◆ Current state
Filigran ships an OpenCTI weekly build plus backports to two LTS lines (7.2603 and 7.2608). The 10-16 weekly lets analysts merge entities directly from the knowledge view, search defanged indicators globally, collapse the ATT&CK pattern matrix and trim empty sections from generated Fintel reports. Earlier weeklies added enrichment from investigations, chatbot quotas and manual security coverage.
◆ Where it's heading
The arc is analyst ergonomics inside the knowledge graph: fewer context switches to deduplicate, enrich and report, layered on an access-control hardening pass that the LTS patches backport. Many long-standing feature requests (some with issue numbers in the 8,000-14,000 range) are now landing, which suggests a backlog-clearing phase.
◆ Prediction
Expect more old knowledge-view and filter requests to close in coming weeklies, and LTS patches that backport this month's access fixes. The entries don't show when a new LTS line will be cut.
