Frequently Asked Question

What can I use Plurilock for?

The two most common Plurilock use cases are invisible multi-factor authentication (MFA) at login and continuous authentication throughout the workday.

In the case of login MFA via Plurilock ADAPT, logins gain MFA protection invisibly without requiring users to enter additional one-time token codes, SMS codes, provide fingerprint scans, recall answers to “secret questions,” click email links, or perform other traditional yet onerous and failure-prone MFA login “steps.” This provides protection both against the reuse of stolen credentials and against the use of credentials gained through “phishing” attacks.

In the case of continuous authentication via Plurilock DEFEND, corporate workstations and endpoints gain full-session, real-time authentication with the identities of logged in users checked every 3-5 seconds silently, in the background. This provides protection against account sharing, session takeovers, data exfiltration from user carelessness, and other forms of insider threats and endpoint attacks.
