What the models said for it

Verbatim evidence the judge attached to positive labels.

“Open XDR platforms (like Elastic, Hunters, Stellar Cyber) offer: Better third-party integration” Kimi K2 · XDR · negative prompt · first choice

“open XDR architectures (like Stellar Cyber) are recommended instead” Mistral Small · XDR · negative prompt · first choice

“Stellar Cyber (Open XDR): Excellent at collecting logs from different firewalls, endpoint agents, and cloud platforms” Gemini 3.5 Flash · XDR · scale prompt · alternative

“Top Recommendation: Stellar Cyber or Blumira XDR ... Best for: Companies that have a variety of existing security tools” Gemini 3.5 Flash · XDR · paraphrase prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Reviews for platforms like ThreatConnect, ThreatQ, and Stellar Cyber, for example, mention concerns such as learning curve, API limitations, access-control gaps” GPT-5.4 mini · Threat intel · negative prompt · soft negative

“reviews mention false positives, telemetry search slowness, and dashboard/reporting limits” GPT-5.4 mini · XDR · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Stellar Cyber. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 50 of the 56 answers that named Stellar Cyber and are not a share of its labels.

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Stellar Cyber's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Stellar Cyber, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at stellarcyber.ai is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
