Keeper's zero-knowledge architecture encrypts every individual record and folder with its own unique AES-256 key, with all encryption and decryption performed locally on the user's device. Keeper's "Transmission Security" adds a second layer – TLS 1.3/1.2 plus an additional 256-bit AES transmission key – covering all data communications, not just authentication. HSM integration in AWS provides super-encryption at rest.
Keeper Forcefield technology protects against memory-based attacks that specifically target password managers.
Keeper's self-managed BreachWatch® dark web monitoring runs entirely within its own infrastructure using an HSM-protected architecture, so breached passwords are never correlated against vault data outside Keeper's systems.
Keeper holds 10 issued U.S. patents covering its zero-knowledge architecture, SSO, breach detection and secure messaging, with four more pending.
Based on publicly available documentation, 1Password uses a vault-key-based encryption model: individual items are encrypted using keys derived from that vault key, rather than each having an independently generated key. Its SRP protocol handles authentication; data in transit is protected by TLS, though this operates separately from 1Password's credential encryption architecture.
For dark web monitoring, 1Password's Watchtower feature integrates with Have I Been Pwned using a k-anonymity API, which transmits only a partial hash rather than the full credential.
1Password provides basic memory protection only, leaving users more exposed to advanced malware techniques that target password managers.
1Password (AgileBits Inc.) holds at least one issued U.S. patent.
Keeper uses multi-layered authentication that combines a master password with device verification, providing an approach that is both attack-resistant and simple for end users.
Keeper has been in enterprise SSO production since 2016, holds patents on its SSO implementation and supports complex multi-provider configurations with no additional software required.
SCIM provisioning works directly with any Identity Provider (IdP) without any software installation.
Based on publicly available documentation, 1Password's dual-factor approach, an account password plus a secret key, can introduce complexity and potential access issues.
SSO support has expanded to multiple identity providers, though deployment requires additional configuration steps compared to Keeper's no-software-installation approach.
SCIM provisioning requires deploying a self-hosted SCIM Bridge in either an on-premises or cloud environment, though 1Password now offers hosted provisioning for Entra ID and Okta users.
KeeperPAM combines enterprise password management, secrets management, connection management, privileged session management and Remote Browser Isolation (RBI) in a single cloud-native, zero-knowledge interface.
Remote Browser Isolation creates isolated browser sessions for internal and cloud applications, eliminating the need for VPNs.
Keeper Endpoint Privilege Manager enforces Just-In-Time (JIT) access and least privilege directly on user devices, with automatic privilege revocation on session termination.
Keeper Secrets Manager is fully cloud-based with CLI, REST APIs, Terraform and CI/CD pipeline support. No on-premises infrastructure is required.
Keeper also offers over 80 distinct permissions across 14 categories for granular enterprise access control.
1Password is a password manager that has expanded into an Extended Access Management platform covering device trust, SaaS visibility and app access governance. It does not offer the privileged access management capabilities that enterprises typically require, including RBI, JIT or zero-standing privilege capabilities, or the ability to enforce least privilege on endpoints.
For secrets management, 1Password Secrets Automation offers two paths: Service Accounts for lighter use cases or a self-hosted Connect Server deployed in the customer's own infrastructure for teams needing more control, scalability and higher request limits. Both require configuration and ongoing maintenance within the customer's environment.
1Password has 12 vault-based permissions with limited granularity for enterprise access control.
KeeperDB provides secure, zero-knowledge remote access to databases, including MySQL, PostgreSQL, SQL Server and more, directly through the browser with no client software required. Access is governed by role-based policies, full session recording and audit logging, ensuring every database interaction is tracked and compliant. Credential injection means users never see or handle the underlying database passwords directly.
Based on publicly available documentation, 1Password has no database access or management capabilities. Organizations using 1Password for database credentials must rely on manual credential retrieval and separate tooling to manage and audit database sessions, with no native session recording or policy enforcement.
KeeperAI brings intelligent automation to privileged access management. It monitors privileged sessions in real time and can automatically terminate a session when suspicious activity is detected. KeeperAI also assists with policy creation, access reviews and anomaly detection, reducing the manual overhead of managing a large privileged access environment while continuously strengthening security posture.
Based on publicly available documentation, 1Password has no AI-powered privileged session monitoring, real-time anomaly detection within sessions or automated security response capabilities such as automatic session termination upon detecting suspicious activity.
While 1Password's recently launched Unified Access platform provides credential audit trails and visibility into AI agent activity, it does not offer the integrated session intelligence that KeeperAI delivers natively within a full PAM platform.
Keeper supports time-limited record and folder sharing with automatic credential rotation, plus bidirectional one-time sharing to both users and non-users with real-time sync. Its node-based organizational architecture supports isolation between business units and multiple identity providers within the same tenant.
Enterprises have multiple account recovery pathways, including SSO Recovery, Account Transfer Policy, a 24-word recovery phrase and Commander CLI automation.
Keeper's MSP platform, launched in 2019, combines password management with full PAM capabilities in a unified, multi-tenant interface.
1Password requires users to create separate vaults for sharing, producing copies of records rather than real-time, synced data. It has no node structure or organizational units, and guest accounts are limited to a single vault with no time controls or automated security measures.
There is no direct vault transfer between user accounts, and offboarding relies on employees manually moving items before they leave, with account recovery as an admin fallback that requires access to the departing employee's email address.
1Password's MSP offering focuses solely on password management with no PAM features.
Keeper is FedRAMP High Certified and GovRAMP High Authorized, FIPS 140-3 validated, ISO 27001/17/18 certified, ITAR compliant and holds the longest-standing SOC 2 Type II certification in the industry.
Based on publicly available information, 1Password holds no FedRAMP, GovRAMP or FIPS authorization, limiting its use in regulated industries and government.
