By framing
What the models said for it
Verbatim evidence the judge attached to positive labels.
“vendors (like Corelight) that allow you to deploy unlimited virtual sensors and charge based on enterprise-wide licensing rather than gigabyte-level "taxes"” Gemini 3.5 Flash · NDR · negative prompt · first choice
“SMBs can leverage Corelight or Awake Security for cost-effective monitoring” Claude Haiku 4.5 · NDR · budget prompt · first choice
“Corelight (based on Zeek) or open-source Zeek are the best choices” Mistral Small · NDR · budget prompt · first choice
“best if your team is more technical and wants an open, highly extensible network-security-monitoring approach” GPT-5.4 mini · NDR · direct 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.
“Corelight — commercial Zeek sensors start around $150K+/year” DeepSeek V4 Flash · NDR · budget prompt · hard negative
“For open-telemetry platforms such as Corelight buyers are warned about "Cost growth tied to throughput, sensor count, data retention, or site expansion"” Muse Glimmer 30B · NDR · negative prompt · soft negative
“It can be powerful, but it may still require more in-house skill and infrastructure than a true budget buyer wants.” GPT-5.4 mini · NDR · budget prompt · soft negative
“Great if you want an open-source (Zeek) foundation, but usually requires a more mature security team to operate.” Gemini 3.5 Flash · NDR · scale prompt · soft negative

How it is countedHide how it is counted
Every page corelight.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person. Read October 5, 2026.
