Every category where a model named c/side for a mid-market B2B company. Share is first choices across the direct, paraphrase, budget and scale prompts; rank is within every product named in that category.

Movement

This is the first edition on this tier, so no move can be computed for c/side yet. From the next edition this section shows, per buyer segment and per category, whether its share moved by more than the measured noise floor.

By model

How each model treated c/side across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“My top pick: For most small-to-mid-size companies, c/side at $99/month delivers enterprise-grade client-side protection” DeepSeek V4 Flash · Client-side protection · budget prompt · first choice

“If you need to block attacks in real time before they execute → c/side or Source Defense” DeepSeek V4 Flash · Client-side protection · comparative prompt · first choice

“I'd recommend starting with c/side (free tier) or Source Defense Essentials ($98/month)” Kimi K2 · Client-side protection · direct prompt · first choice

“Top Recommendation: c/side” Kimi K2 · Client-side protection · paraphrase prompt · first choice

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.

No model argued against it.

A head-to-head page exists where both products are among a category's top eight. The other rows are the same fact without a page behind them, so they link to the product instead.

What carried it into the answer

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

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 16 of the 16 answers that named c/side and are not a share of its labels.

How it is countedHide how it is counted

Every page cside.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.

Is this your product?

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 c/side'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 c/side, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for c/side by email, built from the raw record of the edition. It shows:

where c/side is named, by buyer and by framing, and which cells hold its first choices;
the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
its vocabulary against the segment leader's, and the pages the models cited;
who was chosen in the answers that did not name c/side, and every reason the record gives;
a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
one page of published figures cleared to show a buyer.
