What the models said for it
Verbatim evidence the judge attached to positive labels.
“Choose In-Browser Runtime Agents (Source Defense / HUMAN) if you operate a high-volume checkout or login page and want *active prevention*” Gemini 3.5 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
“I'd start with Source Defense's PCI Compliance product for a mid-sized B2B company” GPT-6 Luna · Client-side protection · paraphrase prompt · first choice
“Source Defense is repeatedly called out for mid-market and enterprise teams managing third-party vendor ecosystems.” Muse Glimmer 30B · Client-side protection · 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.
“solutions from vendors like JScrambler, Reflectiz, Source Defense, and Human Security ... often fail to block the majority of sophisticated e-skimming attacks” Qwen 3.7 Flash · Client-side protection · negative prompt · soft negative
“Popular vendors include Human Security, SourceDefense, JScrambler, and Reflectiz. ... JS agents detect behavior after a script has already executed.” Muse Glimmer 30B · Client-side protection · negative prompt · soft negative
“you do not need to pay $15,000+ per year for enterprise-grade solutions (like Akamai, Jscrambler, or Source Defense)” Gemini 3.5 Flash · Client-side protection · budget prompt · soft negative
“Claims to protect against Magecart, but independent testing shows it can be evaded by obfuscated scripts.” MiniMax M2.5 · Client-side protection · negative prompt · soft negative

How it is countedHide how it is counted
Every page sourcedefense.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.

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 Source Defense'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 Source Defense, 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
