Keeper

No — there has never been a breach of Keeper's customer vaults. In 2017 a researcher reported a flaw in its browser extension, which Keeper patched within a day with no data lost. Its zero-knowledge architecture is certified to SOC 2 and ISO 27001, an unusually formal compliance record for a consumer password manager.

Keeper stores, generates and autofills passwords with a distinctly business-grade security posture. Its vaults are zero-knowledge and formally certified, and it adds secure sharing controls, emergency access, and optional paid add-ons such as secure file storage and BreachWatch dark-web monitoring. Where rivals lead on flashy extras, Keeper's pitch is certified rigour: the same architecture trusted by enterprises and, via FedRAMP, US government users. It's aimed at people and families who want provably audited, compliance-grade protection rather than the most playful interface.

Keeper Unlimited starts at US$3.58/mo for one person across unlimited devices, and Keeper runs frequent first-year promotions of around half off, so watch for a discount at sign-up. The Family plan covers five separate vaults and is the better-value option for a household. There's no meaningful free tier, but a 30-day trial lets you test the apps and the vault properly before committing to a subscription.

Yes — Keeper is one of the most rigorously certified managers here. It uses zero-knowledge AES-256 encryption and holds SOC 2 Type II and ISO 27001 certification, plus FedRAMP authorisation for US government use, and it's independently audited on a regular basis. Among our seven, it carries the most formal security credentials.

Only in a very limited way: Keeper Free runs on a single mobile device with no sync, which makes it a taster rather than a usable solution. For a genuinely capable free tier, Bitwarden or Proton Pass are the ones to pick. Keeper's real strength is its certified, business-grade paid product.

Keeper is made by Keeper Security, Inc., a privately held US company based in Chicago. It was founded in 2011 by Darren Guccione and Craig Lurey, who still run it today, with a minority growth investment from Insight Partners. There's no big-tech parent behind it.
