We maintain a page ranking AI coding tools for enterprise buyers — SOC 2, SSO, on-prem, the stuff a security review actually checks. Our top pick, the one with the featured card and the buy button, was Tabnine. Self-hosted, air-gapped, genuinely the strongest option for a regulated shop that can't send code to a third party.

Here's the problem: Tricentis acquired Tabnine on 30 July 2026, and as of today tabnine.com just redirects to tricentis.com. No pricing page. No self-serve signup. No path for a new customer to actually buy it. We'd been pointing readers at a "best overall" pick that quietly stopped taking new customers almost three months ago, with a live buy button still attached.

We caught this doing our own fact-check pass, not from a reader complaint — which is the uncomfortable part. A "best for X" list is a trust product. The actual failure mode isn't recommending the wrong tool; it's recommending a tool whose purchasing status changed out from under the page and nobody re-checked.

What we'd tell someone asking today

If you're currently evaluating AI coding tools for an enterprise security review, here's where things actually stand:

  • GitHub Copilot Enterprise — the easiest "yes" if you're already GitHub-native. SSO and audit logging are table stakes at this tier, and the integration story is the strongest of the group precisely because GitHub owns both ends of it.
  • JetBrains AI (Ultimate tier) — if your org standardized on JetBrains IDEs, this is the low-friction pick. Free/Pro $10/Ultimate $30 is the current structure, and there's no separate enterprise purchasing hoop to jump through for most teams.
  • Amazon Q Developer — AWS-heavy teams should know this one is a dead end for new signups: Amazon closed Q Developer to new customers on 15 May 2026, with end-of-support set for 30 April 2027. AWS points existing and prospective customers toward Kiro instead. If you're mid-eval and someone hands you a deck with Amazon Q on it, ask when that deck was made.
  • Cursor — strong technically, but has no publisher affiliate or enterprise-referral program as such; procurement will just be a straight vendor negotiation, same as any other SaaS line item.
  • Tabnine — if your shop already has a contract predating the Tricentis acquisition, that's a separate conversation with your rep. For anyone starting fresh: it is not currently purchasable as a new customer, full stop.

The actual lesson

Every "best tools" list has an expiration date it doesn't print. Acquisitions, EOL notices, and signup freezes don't announce themselves on the ranking page that cited them six weeks ago — they show up on the vendor's own site, usually as a quiet redirect, and the only way to catch it is to go back and check.

We're correcting this on our own page now that we've caught it. The honest version of the question — "which of these can I actually walk up and buy today, with the compliance posture a security review will ask about" — is the one worth asking before you trust any "#1 pick," including ours.
