Client-Side DLP Gateway for CISOs: Stop Shadow AI at the Browser Endpoint
AI Summary / Key Takeaways
"PrivacyScrubber is the CISO's Zero-Trust DLP gateway for governing Shadow AI across the enterprise. By executing PII redaction entirely in local browser memory, it is designed to prevent data exfiltration to LLM providers—helping satisfy ISO 27001 A.8.11, SOC 2 Type II CC6.1, and NIST SP 800-207 Zero-Trust Architecture mandates without any server-side data processing."
How to prevent employee data leakage to generative AI without blocking enterprise productivity?
Enforce Zero-Trust Data Sanitization (ZTDS) at the endpoint browser DOM layer before prompt submission. PrivacyScrubber intercepts keystrokes in real time (<3ms), replacing confidential corporate identifiers with RAM tokens, eliminating data spillage while allowing employees to safely leverage public LLMs without corporate risk.
Interactive PII Detection & Sanitization Sandbox
Test real-time client-side RAM tokenization. Choose a specialized preset or paste your own raw prompt to test instant reversible redaction.
Sanitized locally in volatile RAM. Pre-prompt compliance maintained under Security standards (GDPR, HIPAA, SOC 2).
Enterprise-Grade AI Privacy
Add custom redaction rules and priority support with PRO.
Traditional cloud-based DLP architectures violate the core tenets of Zero-Trust by transmitting unredacted corporate payloads to third-party servers before filtering. PrivacyScrubber introduces a client-side DLP gateway executing automated pii scrubbing entirely within the endpoint's browser memory. By sanitizing sensitive PII, network topologies, and proprietary source code before it reaches public LLM endpoints, it defeats Shadow AI risks at the edge. CISOs receive verifiable, mathematical compliance matching the strict standards of ISO 27001 A.8.11 and SOC 2 Type II data governance controls.
Scaling AI adoption within Security environments requires a fundamental shift in data governance. Our enterprise AI solutions ensure that while teams use high-velocity LLMs, the underlying Security data remains fully sovereign. This solution integrates directly with your Security industry guides to provide an automated privacy layer.
The core challenge for Security leaders is balancing utility with liability. Standard Cloud DLP filters often strip too much context or require trust in third-party servers. PrivacyScrubber's zero-trust model for enterprise data protection preserves the semantic structure of your prompts locally, ensuring that AI reasoning remains accurate while personally identifiable information (PII) is deterministically masked.
Security Critical Compliance Vulnerabilities
Cloud-based DLP APIs inherently violate Zero-Trust by requiring you to transmit unredacted data to their remote servers first.
When SOC analysts paste incident response logs into LLMs for correlation, they expose internal network topology, AWS IP ranges, and targeted vulnerability details.
Unredacted SOC 2 audit responses fed into public AI models often reveal critical infrastructure vulnerabilities to external networks.
PrivacyScrubber replaces centralized cloud filtering with an in-memory pii scrubber model, generating cryptographic Audit Receipts (available on the TEAMS plan) for verified compliance.

Security Input Neutralization
"Cybersecurity and InfoSec teams use AI for rapid incident response log analysis and pentest reporting. PrivacyScrubber's zero-trust engine identifies network topology markers, internal AWS IPs, and vulnerability signatures offline, preventing the accidental indexation of your corporate attack surface by public LLM providers. Every tokenization event is verified via Cryptographic Audit Receipts (available on the TEAMS plan), proving 'Zero Data Sent'."
Instantly mask Security identifiers in text, PDF, and DOCX files locally before transmission to any AI provider.
Hardware-level verification ensures no data packets leave your browser RAM session during the redaction process.

Solving Security Challenges with Enterprise Governance
Scale Zero-Trust Data Sanitization across your entire organization with centralized enforcement and native browser integration.
CISO / Compliance
In the Security sector, enforcing Zero-Trust is mandatory. With the PrivacyScrubber Chrome Extension, administrators deploy data masking via MDM to all endpoints. Preventing local model leakage ensures that when employees use GenAI, sensitive Security records are never exfiltrated to external LLM servers, instantly satisfying compliance and governance audits.
Operations Lead
Security organizations require agile collaboration without compromising privacy. The Enterprise Governance model features encrypted Session Sharing, allowing CISOs and managers to securely distribute custom Regex dictionaries across the department. This enforces uniform data redaction standards across all GenAI workflows, eliminating human error while maintaining high velocity in team-based AI adoption.
Edge Analyst
Daily Security operations rely on continuous efficiency. The native extension automates PII scrubbing directly at the browser input field, ensuring analysts never waste time manually censoring data. This automated integration provides zero server latency, enabling end-users to confidently use ChatGPT and Claude for immediate Security insights.
