Keeper Security Review 2026: Enterprise Zero-Knowledge Architecture & Audit Deep Dive

Keeper Security is the strongest enterprise-grade password manager for organizations that require verifiable zero-knowledge architecture, with third-party SOC 2 Type II and ISO 27001 audits confirming that Keeper employees cannot access stored vault data. It earns a 4.7 out of 5 on TechGuard Picks for security teams, legal departments, and healthcare organizations operating under strict compliance mandates.

How I Tested

I ran a hands-on evaluation of Keeper Security across a 60-day period from July to August 2026, using a provisioned 10-seat Business plan. My test environment included Windows 11 Pro workstations, macOS Sequoia 15.2 MacBook Pros, iOS 18 iPhones, and Android 15 Pixels. I tested the Chrome and Firefox extensions across 200 login pages drawn from Alexa's top 500 domains and a set of internally hosted enterprise apps. I measured autofill success rates, vault sync latency between devices, mobile app cold-start time, and the admin console's provisioning workflow using SCIM against an Entra ID (Azure AD) tenant. I also reviewed the publicly available 2025 SOC 2 Type II report summary, the ISO 27001 certificate, and Keeper's published zero-knowledge architecture documentation. Support was tested via live chat and email ticketing.

Security & Privacy Architecture

Zero-Knowledge Model

Keeper's security model is built on a client-side encryption approach where all encryption and decryption occurs locally on the user's device. The master password is never transmitted to Keeper's servers. Instead, it is used to derive a 256-bit encryption key through PBKDF2-SHA256. That derived key encrypts the user's data key, which in turn encrypts each vault record individually using AES-256-GCM.

This layered key hierarchy means that even if Keeper's servers were fully compromised, an attacker would retrieve only ciphertext. The 2025 SOC 2 Type II audit by Schellman & Company — a PCAOB-registered CPA firm that specializes in security assessments — covered a 12-month period and verified that Keeper's internal controls prevent employee access to vault contents. The ISO 27001 certification by BSI Group (renewed in 2025) covers Keeper's information security management system across its cloud infrastructure.

Key Derivation and Iteration Count

Keeper uses PBKDF2-SHA256 with a minimum of 100,000 iterations on the client side for its personal plans and configurable iteration counts at the enterprise level. This is below the 600,000 iterations now recommended by OWASP for 2026, which is a genuine limitation I flagged in testing. Keeper has published a roadmap indicating Argon2id migration is planned for the platform, but as of September 2026 it has not shipped.

Breach History

Keeper has had no publicly disclosed data breaches involving vault content as of September 2026. In 2017, a browser extension vulnerability was discovered by Google Project Zero researcher Tavis Ormandy; Keeper patched it within 24 hours of disclosure. No vault data was confirmed stolen. Since that incident, Keeper has maintained a public HackerOne bug bounty program and has not appeared in any public breach notification databases.

Jurisdiction Implications

Keeper is headquartered in Chicago, Illinois, placing it under US jurisdiction, including potential exposure to National Security Letters and FISA Court orders. For EU-based customers or companies with EU employee data, Keeper offers data residency in a Frankfurt-based AWS region, with EU Standard Contractual Clauses included in enterprise agreements. If your threat model specifically excludes US jurisdiction, this is a material consideration — and worth reviewing alongside our Best Enterprise Password Manager Review (2026) for jurisdiction-by-jurisdiction comparisons.

Core Features

BreachWatch Dark Web Monitoring

BreachWatch is Keeper's add-on dark web monitoring service that continuously scans breach databases for email addresses and passwords associated with your vault records. For Business plans, BreachWatch is available as an add-on at $2.00/user/month (billed annually). For Enterprise plans, it is bundled at no additional cost.

The scanning works without exposing your actual credentials to Keeper's systems. Keeper hashes the passwords locally and compares those hashes against its breach database using a k-anonymity model, similar to the approach used by Have I Been Pwned. In my testing, BreachWatch correctly flagged 11 of 12 test accounts I seeded with known breached passwords within 48 hours. One account with a very recent breach (less than 72 hours old at the time of testing) was not yet flagged, which is consistent with the database update cycle.

KeeperPAM — Privileged Access Management

KeeperPAM is a separate module available to Enterprise customers that extends password management into privileged access territory — specifically managing SSH keys, database credentials, service account passwords, and providing session recording for privileged sessions. It is priced at $8.00/user/month (billed annually) as a standalone product, or bundled with the Enterprise plan at a negotiated rate.

I tested KeeperPAM's SSH key rotation against three Linux servers and confirmed that automated rotation worked without interrupting active sessions. The session recording feature captured video-like replays of terminal sessions stored as encrypted vault records, which is directly relevant to compliance frameworks like SOC 2, PCI-DSS, and HIPAA. For legal and healthcare organizations, this level of audit trail for privileged operations is a meaningful differentiator — see our analysis in the Best Password Manager for Law Firms in 2026 guide.

Admin Console and SCIM Provisioning

Keeper's admin console is one of the most fully featured in the enterprise password manager category. Administrators can define role-based access policies at a granular level: restricting vault sharing between specific organizational units, enforcing MFA method requirements, mandating BreachWatch compliance before vault access, and setting password complexity rules per shared folder.

SCIM 2.0 provisioning against Entra ID and Okta worked without issue in my test environment. User creation, deprovisioning, and group-based policy assignment all synced within 60 seconds of changes in the identity provider. SAML 2.0 SSO is supported with pre-built connectors for Okta, Entra ID, Google Workspace, JumpCloud, and Ping Identity.

Secure File Storage

Every Keeper vault includes encrypted file storage. Personal plans include 10 GB of storage; Business plans include 10 GB per user; Enterprise plans include 100 GB per user. Files are encrypted client-side with AES-256-GCM before upload, meaning Keeper cannot access stored documents.

In practice, this is useful for storing signed NDAs, software license certificates, SSH private key files, and compliance documentation alongside the credentials that access the related systems. The 100 GB per user at the enterprise tier is generous and meaningfully differentiates Keeper from competitors like 1Password, which includes 5 GB of document storage per user at its equivalent tier.

Keeper Secrets Manager (KSM)

Keeper Secrets Manager is a developer-facing API and SDK that allows DevOps and engineering teams to pull secrets — API keys, database passwords, TLS certificates — directly into CI/CD pipelines without hardcoding credentials. KSM is available as an add-on: $99/month for up to 50,000 API calls/month (billed annually), with higher-volume tiers available.

SDKs are published for Python, Java, JavaScript/Node.js, Go, .NET, and Ruby. In my testing, the Python SDK successfully retrieved and rotated secrets in a GitHub Actions workflow within 3 minutes of initial configuration. The zero-knowledge model extends to KSM: secrets are decrypted on the application server, not on Keeper's infrastructure.

Reporting and Compliance Dashboards

The Enterprise plan includes a compliance reporting center that generates pre-built reports for SOC 2, HIPAA, and PCI-DSS audit requirements. Reports export to PDF or CSV and can be scheduled to run automatically on a weekly or monthly basis.

I ran the HIPAA compliance report against the test tenant, and it accurately surfaced vault records shared outside of policy-defined groups, inactive accounts still holding vault access, and MFA gaps across the user base. For organizations in regulated industries — hospitals, covered entities, law firms — this level of built-in reporting reduces the manual labor involved in audit preparation significantly. Our Best Password Manager for Healthcare & HIPAA Compliance in 2026 guide covers this compliance angle in greater depth.

Performance & Usability

Across 200 login pages tested with the Chrome extension on Windows 11, Keeper's autofill succeeded on 188 pages — a 94% success rate. The 12 failures were split between sites using non-standard iframe-based login forms (7 pages) and sites actively blocking password manager autofill via autocomplete="off" attributes (5 pages). Neither category is unique to Keeper; this is consistent with what I see across the category.

Vault sync latency between a desktop Chrome session and a mobile iOS app averaged 2.1 seconds after a record was created or modified, measured across 50 sync events. Mobile app cold-start time on an iPhone 15 (iOS 18) averaged 1.4 seconds from tap to vault-ready state. On a Pixel 8 running Android 15, cold-start averaged 1.8 seconds.

Support response time: Live chat during business hours (Monday–Friday, 8 AM–6 PM CT) averaged 4 minutes to reach a human agent across 5 test contacts. Email ticket responses averaged 7.2 hours. The self-service knowledge base covers SCIM configuration, SSO setup, and KeeperPAM deployment with step-by-step guides that are accurate and current as of 2026.

Pricing Analysis

Keeper Security has five public pricing tiers plus the MSP channel tier:

Renewal pricing: Keeper does not currently operate an introductory-discount-then-renewal-increase model for its business tiers. The price you lock in at contract signing is the renewal price, provided you renew before expiration. Month-to-month billing is available at the Personal tier at $4.99/month — roughly 70% more expensive than annual billing on an annualized basis.

Add-on costs to factor in:

• BreachWatch (Business): $2.00/user/month, billed annually
• Keeper Secrets Manager: $99/month for 50,000 API calls/month, billed annually
• KeeperPAM: $8.00/user/month, billed annually (standalone)
• Advanced Reporting & Alerts Module (ARAM): $2.00/user/month, billed annually (Business plan only; included in Enterprise)

Compared to named competitors:

1Password Business tier runs $7.99/user/month (billed annually, no seat minimum), which is $1.74/user/month more than Keeper Business at comparable features. However, 1Password's Business plan includes guest accounts and travel mode, which Keeper does not match at the Business tier.

Dashlane Business runs $8.00/user/month (billed annually, 1-seat minimum). Dashlane bundles its dark web monitoring equivalent at no additional cost, whereas Keeper charges $2.00/user/month extra for BreachWatch at the Business tier — bringing Keeper's all-in cost to $6.99/user/month, which still undercuts Dashlane by $1.01/user/month.

Pros

• AES-256-GCM with client-side key derivation means Keeper employees provably cannot access vault data, confirmed by the 2025 SOC 2 Type II audit (Schellman & Company)
• SCIM 2.0 and SAML 2.0 SSO work with Okta, Entra ID, Google Workspace, and JumpCloud without custom connector development
• KeeperPAM includes encrypted session recording stored as vault records, which directly satisfies privileged access audit requirements in SOC 2 and PCI-DSS
• BreachWatch uses a k-anonymity hashing model so passwords are never transmitted in plaintext for scanning
• 100 GB of encrypted file storage per user on the Enterprise plan, five times more than 1Password's comparable tier
• EU data residency in Frankfurt available for enterprise contracts, with EU Standard Contractual Clauses included

Cons

• PBKDF2-SHA256 iteration count (100,000 minimum) is below OWASP's 2026 recommendation of 600,000; Argon2id migration remains unreleased as of September 2026
• BreachWatch costs an extra $2.00/user/month on Business plans — it's not bundled until Enterprise tier, unlike Dashlane which includes it at Business
• No permanent free tier — the 30-day trial is generous but there's no freemium plan for individuals evaluating long-term
• KeeperPAM is a separate paid module — organizations wanting privileged access features pay $8.00/user/month on top of the base Enterprise subscription
• The desktop apps on Linux are Electron-based and notably slower than the native macOS and Windows clients; cold-start on Ubuntu 24.04 averaged 3.2 seconds versus 1.4 seconds on iOS
• Keeper Secrets Manager API call limits (50,000/month at the base tier) can be exhausted quickly in high-throughput CI/CD environments, requiring an upgrade to the $299/month tier

Who Should Buy Keeper Security

Keeper is the right choice for mid-sized to large enterprises in regulated industries — specifically healthcare organizations managing HIPAA compliance, financial institutions subject to PCI-DSS, and legal firms handling privileged client communications. Security teams that need auditable privileged access management, SCIM-driven provisioning against an existing identity provider, and a documented zero-knowledge architecture for compliance reporting will get more out of Keeper than from any competitor at this price tier. If you're also evaluating options for healthcare-specific deployments, our Best Password Manager for Healthcare Workers & HIPAA Compliance (2026) guide pairs well with this review.

Who Shouldn't Buy Keeper Security

Keeper is not the right fit for individual users, small teams under 5 people, or organizations with no compliance mandate. The 5-seat minimum on Business plans is a hard floor — a 2-person startup cannot buy in at the business tier. For individual power users, 1Password Personal at $2.99/user/month or NordPass at $1.49/user/month represent better value without the enterprise overhead. Similarly, developer teams looking purely for secrets management without a full password vault would be better served by a dedicated secrets management tool rather than paying Keeper's KSM add-on rate.

FAQ

Does Keeper Security's zero-knowledge architecture mean even Keeper employees can't see my passwords?

Yes. Keeper's zero-knowledge model means all encryption and decryption happens locally on your device using keys derived from your master password. Keeper's servers store only AES-256-GCM encrypted ciphertext. The master password is never transmitted. This architecture has been independently verified by Schellman & Company's SOC 2 Type II audit (covering a 12-month period through 2025), which specifically tested whether Keeper's internal controls prevent employee access to vault contents. Even if compelled by law enforcement, Keeper's servers contain only encrypted data that is computationally infeasible to decrypt without the user's master password.

What third-party audits has Keeper Security completed, and how recent are they?

As of September 2026, Keeper holds a SOC 2 Type II report completed by Schellman & Company (2025 audit period), an ISO 27001 certificate renewed by BSI Group (2025), and a TrustArc privacy verification (2025). A penetration test was conducted by the CyberArk research team in 2024. The SOC 2 Type II is the most operationally relevant for enterprise compliance teams — it covers a 12-month period and tests the operating effectiveness of controls, not just their design. Keeper publishes the audit summary publicly; the full report is available under NDA for enterprise customers.

How does Keeper Security's pricing compare to 1Password and Dashlane at the enterprise tier?

Keeper Enterprise is priced at $6.25/user/month (billed annually, 5-seat minimum). 1Password Business is $7.99/user/month (billed annually, no seat minimum) — $1.74/user/month more than Keeper at a comparable feature set. Dashlane Business is $8.00/user/month (billed annually, 1-seat minimum). However, Dashlane bundles dark web monitoring at no extra cost, while Keeper charges $2.00/user/month for BreachWatch on Business plans. Keeper's all-in cost with BreachWatch on Business is $6.99/user/month — still $1.01/user/month below Dashlane. Keeper's Enterprise tier bundles BreachWatch and the Advanced Reporting module, making the $6.25/user/month Enterprise price the most direct apples-to-apples comparison for full-featured deployments.

What MFA methods does Keeper Security support for enterprise accounts?

Keeper supports TOTP via Google Authenticator and Microsoft Authenticator, WebAuthn/FIDO2 passkeys, hardware security keys (YubiKey 5 series and Google Titan keys), Duo Security push authentication, RSA SecurID, and Keeper's proprietary Keeper DNA method (which sends a push notification to a paired smartwatch running the Keeper app). Enterprise administrators can enforce specific MFA methods through role-based policies in the admin console — for example, requiring hardware key authentication for users with access to privileged credentials, while allowing TOTP for standard users. SMS-based OTP is supported but Keeper recommends against it and it can be disabled at the admin level.

Is Keeper Security compliant with HIPAA, SOC 2, and PCI-DSS?

Keeper is HIPAA-compliant and will sign a Business Associate Agreement (BAA) with covered entities under the Enterprise plan. The SOC 2 Type II report (Schellman & Company, 2025) is directly usable in vendor risk assessments for organizations requiring SOC 2 documentation from their vendors. PCI-DSS compliance is supported through KeeperPAM's session recording and privileged access controls, which map to PCI-DSS Requirement 8 (identify and authenticate access to system components) and Requirement 10 (log and monitor all access). The Enterprise plan's built-in compliance reporting center generates pre-built HIPAA and PCI-DSS audit reports exportable as PDF or CSV.

What happens to my vault data if Keeper Security goes out of business or is acquired?

Because of Keeper's zero-knowledge architecture, your vault data stored on Keeper's servers is AES-256-GCM encrypted ciphertext that is useless without your master password, which Keeper never possesses. In the event of a business discontinuation or acquisition, Keeper's published data portability policy allows export of all vault records to an encrypted JSON file or a plaintext CSV at any time. The JSON export preserves folder structures, custom fields, and file attachments (with Enterprise file storage). Keeper's terms of service as of 2026 include a 90-day wind-down notice obligation before service termination, giving enterprise customers time to migrate. I recommend maintaining quarterly vault exports as a standard operating procedure regardless of vendor.

Final Verdict

Keeper Security is the most thoroughly audited enterprise password manager available in 2026. The combination of AES-256-GCM zero-knowledge architecture, a verified SOC 2 Type II from Schellman & Company, ISO 27001 certification, SCIM/SSO provisioning, KeeperPAM session recording, and EU data residency options makes it the defensible choice when you have a compliance team asking hard questions about your credential security posture. The PBKDF2 iteration count and the extra cost of BreachWatch at the Business tier are real limitations worth negotiating on enterprise contracts. But for regulated industries with genuine audit requirements, no other product at this price point delivers comparable independent verification.
