Detect Password Exposure to Prevent Account Takeover
Detect corporate password reuse at the moment of entry, correct unsafe behavior, and prevent account takeover (ATO) attacks.
Control corporate password usage beyond your environment
SSO Password Guard is a browser-based control that monitors and detects corporate credential reuse on external websites. It helps prevent account takeover by identifying when corporate passwords are reused outside your environment and enabling real-time intervention. This reduces credential exposure, lowers account takeover risk, and gives you insight into where and how users create risk.
Detect corporate password reuse when users submit credentials to unauthorized or suspicious websites.
Gain visibility into where users enter passwords and identify individuals who repeatedly create account takeover risk.
Reinforce secure behavior with in-the-moment guidance when users take unsafe actions, reducing repeat credential misuse.
Uncontrolled corporate password reuse creates real breach risk
Employees routinely reuse corporate passwords across SaaS and external websites, creating exposure beyond the organization’s control. Once exposed, attackers can use these credentials to access accounts while posing as legitimate users.
Reduce the likelihood of exposing corporate passwords
Proofpoint SSO Password Guard helps prevent account takeover by detecting password reuse at the point of entry. When an employee enters a corporate password on an unauthorized or suspicious site, it triggers real-time intervention and captures context on the user and destination. This allows you to enforce credential-use policies and reduce account takeover risk.
Password Reuse Detection
Identify when corporate passwords are entered on unauthorized or suspicious sites.
Real-Time Browser Intervention
Interrupt password reuse at the moment of entry during authentication or account registration.
User Risk Visibility
See which users repeatedly expose credentials and prioritize high-risk behavior.
Website Risk Insight
Understand where passwords are entered and quickly assess exposure risk.
In-the-Moment User Guidance
Prompt users in real time to correct unsafe behavior before credentials are exposed.

Why doesn’t single sign-on (SSO) alone prevent account takeover?
Single sign-on simplifies authentication and access control, but it does not prevent users from entering corporate credentials into external or unauthorized sites. If those credentials are exposed through password reuse ...Single sign-on simplifies authentication and access control, but it does not prevent users from entering corporate credentials into external or unauthorized sites. If those credentials are exposed through password reuse or phishing, attackers can still use them to access accounts. Preventing account takeover requires controlling how credentials are used before they are submitted.

Why don’t password managers prevent password reuse risk?
Password managers help generate and manage strong passwords, but they do not fully prevent password reuse. Users can still manually enter corporate credentials into external sites or reuse passwords ...Password managers help generate and manage strong passwords, but they do not fully prevent password reuse. Users can still manually enter corporate credentials into external sites or reuse passwords across accounts. Additional controls are needed to monitor behavior and enforce password reuse prevention at the point of entry.
