SSO Password Guard
Detect corporate password reuse at the moment of entry, correct unsafe behavior, and prevent account takeover (ATO) attacks.
Overview
Proofpoint SSO Password Guard is a browser-based control that monitors and detects corporate credential reuse on external websites. It helps reduce the risk of 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 password exposure at entry
Detect corporate password reuse when users submit credentials to unauthorized or suspicious websites.
See where risk is created
Gain visibility into where users enter passwords and identify individuals who repeatedly create account takeover risk.
Correct behavior in real time
Reinforce secure behavior with in-the-moment guidance when users take unsafe actions, reducing repeat credential misuse.
Exposure Protection
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.
Features
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 Proofpoint
Account takeover prevention, not just detection
| Capability | Traditional Identity and Access Controls | Proofpoint SSO Password Guard |
|---|---|---|
| Point-of-entry protection | Focus on authentication and access after credentials are entered | Detects corporate password reuse as users submit credentials, reducing credential exposure before account takeover |
| Password reuse detection | Focus on authentication rather than password reuse on external websites | Detects corporate password reuse on unauthorized, unsanctioned, and phishing websites in real time |
| User guidance | Enforce access controls instead of guiding users during risky credential use | Provides immediate in-browser guidance to help users correct unsafe behavior |
| Credential visibility | Show authentication activity with limited visibility into external credential exposure | Shows where corporate passwords are used and which users create credential exposure risk |
| Behavior improvement | Enforce identity policies rather than reducing password reuse behavior | Reinforces credential policies with targeted interventions based on password reuse |
Stop the full range of attacks targeting your people, including threats, impersonation attempts, and supplier fraud. Proofpoint Collaboration Security Prime extends our human-centric security to messaging and collaboration tools, cloud apps, and the supply chain—all through one integrated platform.

Password reuse creates a direct path for attackers. When users enter the same credentials across multiple sites, a single data breach can expose those credentials. Attackers then use techniques like credential stuffing to gain access to corporate accounts through login pages. This is one of the most common causes of account takeover and identity theft.
SSO Password Guard reduces account takeover risk by detecting corporate credential reuse at the moment of entry. If a user attempts to enter their corporate password on an unauthorized or suspicious site, they receive a real-time warning that they may be exposing valid credentials to an attacker-controlled page. This in-the-moment intervention helps users stop and reconsider before submitting credentials, reducing the risk of credential theft as well as later 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 or phishing, attackers can still use them to access accounts. Preventing account takeover requires controlling how credentials are used before they are submitted.
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.
Effective password reuse prevention requires visibility and control at the moment users enter credentials. Browser-based security measures can detect when corporate passwords are used on external sites and intervene immediately. This approach stops credential exposure before it leads to account takeover.
