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.
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 for exactly what is and isn't for sale.

Two offerings share the name "IDSync" — here's the difference
IDSync (this site, idsync.com) is a buyer-research platform for identity and access software, operated by TetraCore.
IDSync® "Identity Syncronizer" is an Active Directory synchronization product for MSPs, now at identitysyncronizer.com. This domain previously hosted that product's website. Both the research platform and the IDSync® product — including U.S. Trademark Registration No. 4,263,864 and all associated intellectual property, acquired by TRZ Holdings, Inc. — are part of the same corporate family today.
Is IDSync (idsync.com) the same as the IDSync® Identity Syncronizer product?
They are two distinct offerings under common ownership. IDSync at idsync.com is a buyer-research platform for identity and access software — a vendor directory, comparison guides, glossary, and buyer tools. The IDSync® "Identity Syncronizer" is an Active Directory synchronization product for MSPs, now found at identitysyncronizer.com. TRZ Holdings, Inc. acquired the assets of the IDSync® business — including U.S. Trademark Registration No. 4,263,864 and all associated intellectual property — and idsync.com is operated by TetraCore as part of the same family. 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 sold on this site. 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, part of the TRZ Holdings, Inc. family, which also owns the IDSync® trademark and product intellectual property. The directory's coverage is editorially independent: no third-party identity software vendor covered on this site owns, invests in, or controls it.
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.
