Credentials
Saved browser passwords, autofill data, VPN and RDP credentials, SSH keys, certificates, and application logins can turn one infection into multiple entry points.
Stop infostealers
Protect the identities already signed in.
Infostealers harvest browser data, credentials, and active session cookies in silence. A stolen session can let an attacker impersonate a signed-in user and reach email, cloud services, and business applications without entering the password or completing MFA again.
Identity exposure overview
Stealer activity detected
Credentials
Saved credentials
Browser passwords, autofill data, VPN and RDP credentials, SSH keys, and application logins can be packaged into reusable stealer logs.
At risk
Browser sessions
Authenticated sessions
Cookies and authentication tokens can preserve an already-approved session, giving attackers a path around the next password or MFA prompt.
At risk
Local identity
Device and user context
System, browser, and identity details help attackers understand the victim environment and make stolen access easier to reuse.
ProtectedThree major browsersProtect session cookies in Google Chrome, Microsoft Edge, and Mozilla Firefox.
Stop the exfiltration phaseIntercept the outbound transfer even if an infostealer has already collected data.
Signatureless and on-deviceDetect the techniques infostealers rely on without a known hash, strain, or cloud verdict.
The real target
The malware is only the beginning. The real prize is an identity attackers can reuse.
Passwords are only one part of the exposure
Infostealers also target session cookies, authentication tokens, autofill data, VPN and RDP credentials, SSH keys, certificates, and application data.
Active sessions can appear legitimate
A replayed cookie can carry the context of a session that was already authenticated, making malicious access look more like the legitimate user.
One device can expose many services
One employee device may hold active access to email, identity providers, cloud services, messaging tools, VPNs, and internal business applications.
What is at stake
EXPOSURE 01
EXPOSURE 02
EXPOSURE 03
EXPOSURE 04
One infection can expose an entire working identity.
An infostealer does not need to compromise every system directly. It collects the credentials, sessions, and context that let an attacker return later as someone the business already trusts.
Sessions
Cookies and authentication tokens represent active access. When stolen, they may let an attacker hijack a signed-in session and bypass the next MFA challenge.
Device context
Browser profiles, system information, user details, and installed applications help an attacker understand how and where the stolen identity can be reused.
Business access
Compromised access can extend to corporate email, cloud services, identity providers, collaboration platforms, remote access, and the sensitive data available through them.
The exposure chain
Stop the chain before stolen access becomes a breach.
The malware may run only long enough to collect and upload its target data. The stolen credentials and sessions can then be sold, shared, and reused months later as the first link in a larger breach or ransomware attack.
InfectA phishing message, malicious advertisement, or trojanized download executes the stealer on an employee device.
CollectThe malware gathers browser cookies, credentials, tokens, and other identity data into a stealer log.
TransferThe collected data is packaged and uploaded to attacker-controlled infrastructure or an underground marketplace.
ReuseAn attacker hijacks a session or account to reach business systems, steal data, or establish a ransomware foothold.

Protect the identity before it leaves the device.
Ranger combines browser-cookie protection, Application Guardrails, and data-exfiltration prevention on the endpoint. It targets the techniques behind the theft and produces high-fidelity context for the security team.
Recognize suspicious collection
Application Guardrails identify techniques such as hardware-breakpoint abuse, direct or indirect syscalls, AMSI and ETW tampering, and sleep obfuscation.
Separate malware from normal work
Ranger focuses on the underlying techniques and data-flow behavior rather than requiring a known malware family, hash, signature, or AI classification.
Block the theft attempt
Ranger protects browser cookies from theft and can intercept the outbound transfer if an infostealer attempts to exfiltrate collected data.
Give teams useful context
Alerts in OCSF format give SOC, MDR, and XDR workflows high-fidelity evidence for investigation, containment, and estate-wide threat hunting.
Why Ranger
Protection designed for the identity-stealing moment.
Layer browser-session protection, technique-based detection, and exfiltration prevention around the moment an identity is being stolen.
Cookie protection at the sourceProtect browser session data before stolen authentication becomes someone else's access.
Chrome, Edge, and FirefoxCover the browsers most commonly targeted by commodity and advanced infostealers.
No kernel driver requiredApply application guardrails from user mode without code injection or API hooks.
Technique-based detectionRecognize the methods infostealers rely on without waiting for a known signature or strain.
Block the outbound handoffUse Ranger's data-exfiltration protection to stop collected information from leaving the device.
Built for existing workflowsSend high-fidelity alerts in OCSF format into established SOC, MDR, and XDR pipelines.
Common questions
What you need to know.
Clear answers about how Ranger protects browser sessions, works with your existing security, and responds when infostealer activity is blocked.
How is this different from antivirus or EDR?
Ranger complements existing endpoint security by protecting browser session data, detecting the underlying evasion techniques infostealers use, and blocking the exfiltration phase. It does not depend on recognizing a specific malware hash or family first.
Which browsers and identity artifacts are protected?
Ranger provides browser-cookie protection for Google Chrome, Microsoft Edge, and Mozilla Firefox, including protection against theft used for pass-the-cookie attacks. Its exfiltration layer can also stop the outbound transfer of data collected by an infostealer.
What happens when Ranger blocks infostealer activity?
Ranger prevents the targeted behavior or outbound transfer and records high-fidelity telemetry for investigation. The security team can then isolate the device, review affected identities and sessions, and rotate or revoke access where needed.
Take the next step
Stop infostealers before they become someone else’s access.
