Password security is the foundation of cybersecurity. Keeper's powerful password security platform will protect your business from cyberthreats and data breaches related to passwords. Research shows that 81% of data breaches can be attributed to weak passwords. Password security platforms are an affordable and easy way for companies to address the root cause of most data breaches. Your business can significantly reduce the risk of data breaches by implementing Keeper. Keeper creates strong passwords for all websites and apps, then secures them on all devices. Each employee receives a private vault to store and manage their passwords, credentials and files, as well as private client data. Employees will save time and frustration by not having to remember, reset, reuse, or remember passwords. Industry compliance is achieved through strict and customizable role-based access controls. This includes 2FA, usage auditing, and event reporting.

It includes built-in support for OpenID Connect, SAML, OAuth2, and Webhooks, and ships with pre-configured components for login, signup, user management, and organization hierarchies. Whether you're building multi-tenant apps, complex subscription logic, or entitlement enforcement, Frontegg scales with you. Beyond the initial integration, Frontegg offloads identity maintenance from engineering by enabling non-technical teams to manage identity-related tasks through a secure admin portal. Product, Infosec, and Customer Success teams can enforce security policies, manage users, configure auth flows, and respond to customer needs without dev involvement. Security teams can monitor and enforce identity compliance standards through real-time dashboards and built-in audit trails. Frontegg also ensures continuous updates to identity protocols, so developers don't have to worry about chasing evolving standards. Frontegg reduces developer toil, shortens go-to-market timelines, and keeps engineering focused on high-impact product work.
