XpertLync CyberGuard DLP - Standard

In-browser data loss prevention, pre-upload file screening, and exfiltration defense for enterprise endpoints.

XpertLync CyberGuard DLP (Standard Edition) is an in-browser Data Loss Prevention (DLP) and real-time pre-upload file screening solution designed to prevent corporate data breaches and unauthorized data exfiltration before network transmission begins. Traditional network firewalls, Secure Web Gateways (SWG), and Cloud Access Security Brokers (CASBs) inspect packets only after files have already begun encrypting and transmitting across TLS tunnels. XpertLync CyberGuard closes this critical security gap by operating directly inside the browser memory layer—trapping file selections, drag-and-drop operations, and clipboard buffers in real-time, completing deep heuristic inspection, and aborting unauthorized uploads in under 3 milliseconds before a single byte reaches the network socket. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY CAPABILITIES & ENDPOINT DEFENSE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRE-UPLOAD IN-MEMORY FILE SCREENING Intercepts drag-and-drop events and file input triggers across all web applications. The in-memory engine scans file metadata, cryptographic SHA-256 signatures, and content heuristics before allowing release to the web application. 🛡️ TARGETED EXTERNAL CHANNEL DEFENSE Enforce strict zero-upload and conditional access policies on unmanaged public channels including: • Professional Networks & Social Portals: LinkedIn messaging, feeds, Twitter/X, Reddit • Public Generative AI Tools: ChatGPT, Claude, Gemini, Copilot • Webmail & Personal File Sharing: Gmail, Yahoo, WeTransfer, Mega, Dropbox • Collaboration Platforms: Slack web, Discord, external web forums ⚡ SUB-3 MILLISECOND CLIENT-SIDE EXECUTION Engineered using high-performance asynchronous web workers to guarantee zero latency and zero disruption to end-user productivity. Legitimate business file transfers flow uninterrupted. 🔒 100% CLIENT-SIDE PRIVACY (ZERO CLOUD SCANNING) All hash matching, keyword categorization, and policy evaluations execute strictly inside endpoint browser memory. No sensitive enterprise documents, source code, or customer PII are ever uploaded to third-party cloud servers for inspection. 📋 REGULATORY & COMPLIANCE READY Preconfigured out-of-the-box policy templates for: • HIPAA / HITECH: Protected Health Information (PHI) & Medical Records • GDPR / CCPA: Personally Identifiable Information (PII) • PCI-DSS: Credit card primary account numbers (PAN), CVV, and banking records • Intellectual Property: Proprietary source code (.git, .py, .java, .env), SSH keys, API secrets, and CAD models 📊 LOCAL AUDIT TRAILS & REAL-TIME ALERTS Automatically records cryptographic file fingerprints (SHA-256), source hosts, target destinations, timestamps, and policy rule triggers in tamper-resistant local audit buffers. Dispatches instant real-time desktop alerts and administrator email incident notifications upon breach interception. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. User Selects or Drops File: An employee drops or selects a document on an external website (e.g. personal webmail or generative AI portal). 2. Instant RAM Trap: CyberGuard's in-browser gateway intercepts the file buffer inside memory prior to DOM event propagation. 3. Policy Engine Evaluation: SHA-256 hash matching, keyword rules, and domain policies evaluate the payload in < 3ms. 4. Enforcement Decision: If compliant, the upload proceeds instantly. If unauthorized, the file buffer is wiped from memory, zero bytes are transmitted, and the user receives an on-screen policy alert with an incident reference. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ LICENSING & SUPPORT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Designed for workstations, remote professionals, and distributed teams needing immediate endpoint protection. • Simple per-device license key activation directly within the extension options panel. • For enterprise-wide centralized fleet orchestration and server management, Enterprise Edition is also available.
