Prevent Session Hijacking
Webfuse's Cookie Guard encrypts session cookies and binds them to a single session, making them unreadable and unusable after the session ends.
Safely access the web from anywhere while keeping sessions secure, even on public or untrusted devices.
Most web applications rely on HTTP-only session cookies to maintain login state. But once those cookies are in the browser, they can be stolen, copied, or reused. This risk increases significantly on unsecure networks or shared devices.
Webfuse protects against such threats by binding the session cookies to the singular user session, regardless of the web application being browsed.
With Cookie Guard, cookies are encrypted using a session-specific key. When the session ends, any cookies left behind become instantly unusable, even if the original app intended to keep the user logged in for hours or days.
No cookie reuse. No replay attacks. No hijacking.
Session hijacking is still a top attack vector, especially in enterprise environments
- Session cookies can be stolen using malware, browser extensions, or memory tools
- Tokens are often reused without reauthentication
- HTTPS does not protect against compromised devices
- Most platforms lack the tools to revoke access once a cookie is stolen
Once a cookie is stolen, the attacker is the user. And most systems won’t know the difference.
How Webfuse solves this
Webfuse wraps your app in a Virtual Web Session where all authentication cookies are:
- Encrypted and scoped to the current session only
- Automatically invalidated when the session ends
- Unusable outside the Webfuse session, even if stolen
- Sessions can be revoked on demand via API, instantly terminating access
Cookie Guard ensures that no persistent session data can survive beyond the session lifecycle. It works like a self-destruct switch for your login credentials.
Key benefits
- No cookie reuse: Session cookies cannot be reused in another session, browser, or device.
- No delayed logout: Tokens expire in real time when the session ends, not when the app eventually invalidates them.
- No uncontrolled access from shared devices: Access ends with the session. It does not linger in memory or in the browser.
- Backend-Controlled Access Revocation: Sessions can be terminated programmatically via API, cutting off access in real time.
Examples
- Banking Access from Hotel Business Centers: Contain login sessions to a single device and session. Prevent tokens from leaking even on compromised machines.
- Regulated SaaS Platforms (Finance, Healthcare, Legal): Ensure sessions are scoped, time-limited, and compliant with audit requirements, even on public Wi-Fi.
- Vendor or Contractor Access: Grant temporary access to internal tools with session-bound cookies that expire as soon as the session ends. Revoke access instantly via API if needed.

FAQ
Can attackers still reuse session cookies from browser memory?
No. Cookies in Webfuse are encrypted and tied to a specific session. Even if extracted from browser memory, they cannot be used outside the original session context.
Do I need to modify the application or add headers?
No. Webfuse works without requiring changes to the application’s code or server configuration.
What happens when the Webfuse session ends?
Session cookies are encrypted using a unique session token. When the session ends, that token becomes invalid and cannot be reused. As a result, the cookies become unreadable and unusable, even within the same browser or on the same device. They cannot be replayed or reused, even if the original website’s session cookie was intended to remain valid.
