[Home](/) 2. About # About IDSync IDSync is an independent, vendor-neutral research platform that helps IT, security, and engineering teams choose identity, access, and authentication software — IAM, SSO, MFA, CIAM, IGA, PAM, SCIM, machine identity, and AI agent identity. ## What we do Identity software is bought under pressure — renewals, audits, migrations — from vendors that rarely publish comparable information. IDSync exists to make that purchase legible: a curated vendor directory, editorially reviewed comparison and alternatives guides, a plain-language glossary, downloadable buyer resources (RFP templates, migration checklists), and the free [IAM Stack Finder](/stack-finder). We are a research and media business, not a software vendor, reseller, or analyst firm paid by the companies we cover. ## Editorial methodology & disclosure policy ### Published methodology Every ranking explains how it was built: category fit, use case, publicly available information, and editorial review. No pay-to-rank. ### Disclosed sponsorships Sponsored placements carry a visible "Sponsored" label wherever they appear — comparison tables, category pages, and newsletter issues. ### Honest trade-offs Every vendor writeup includes "when not to choose" guidance. A tool that is wrong for you is wrong for you, sponsor or not. ### Verified before purchase Pricing and feature notes reflect what vendors publish, with dates. We tell you to verify with the vendor — because you should. How we make money: clearly labeled sponsorships and buyer-requested vendor introductions. Sponsorship buys placement visibility — never a ranking, a review score, or the removal of critical guidance. See [sponsor options](/sponsor) for exactly what is and isn't for sale. ## Who operates IDSync IDSync is operated by **TetraCore**, a company based in Bowling Green, Ohio, that builds independent research and software products. IDSync is editorially independent: no identity software vendor owns any part of it or has any say in its coverage. Questions about the company? [Contact us](/contact). ## Two products are called "IDSync" — here's the difference **IDSync (this site, idsync.com)** is an independent buyer-research platform for identity and access software, operated by TetraCore. **IDSync® "Identity Syncronizer"** is a separate Active Directory synchronization product for MSPs, made by a different company (Identity Syncronizer), now at [identitysyncronizer.com](https://identitysyncronizer.com). This domain previously hosted that product's website; the two businesses are unrelated. ### Is IDSync (idsync.com) the same as the IDSync® Identity Syncronizer product? No. IDSync at idsync.com is an independent buyer-research platform for identity and access software — a vendor directory, comparison guides, glossary, and buyer tools. The IDSync® "Identity Syncronizer" is a separate Active Directory synchronization product for MSPs, built by a different company, now found at identitysyncronizer.com. The two are unrelated businesses that share a name; this domain previously hosted the synchronizer product's website. ### I'm looking for the Active Directory (AD-to-AD) synchronizer — where did it go? The AD-to-AD Identity Syncronizer product is not made or sold here. You can find that product and its documentation at identitysyncronizer.com (it is also resold by partners such as Form ITS). idsync.com no longer hosts any pages for that product. ### Who operates idsync.com? IDSync is operated by TetraCore, a company based in Bowling Green, Ohio. IDSync is editorially independent: it is not owned by, invested in, or controlled by any identity software vendor it covers. ### How does IDSync make money? Through clearly labeled sponsorships (category and comparison placements, newsletter sponsorships) and by connecting in-market buyers with vendors when buyers ask for a shortlist. Sponsored placements are always disclosed with a visible label, and sponsorship never changes editorial rankings or 'when not to choose' guidance.
