This document clarifies the subscription tiers, included feature sets, purchasing channels, and enterprise customization policies for our two endpoint data loss prevention solutions: USB Disk Security (Standard Edition) and PrivateDLP (Pro Edition). Both solutions adopt a Client/Server (C/S) architecture and support Windows-only endpoint deployment with centralized web-based policy management. This article distinguishes standard core security capabilities and advanced AI-powered enterprise features, explains public and enterprise-only purchasing rules, and details customizable enterprise-grade options for PrivateDLP tailored to business data security and compliance requirements.
1. Product Subscription Tiers Overview
We provide two differentiated subscription editions to match business scenarios from small-team basic protection to large enterprise intelligent data governance and productivity management:
USB Disk Security (Standard Edition): Entry-level DLP subscription focused on fundamental USB security, device access control, and network behavior restriction. Suitable for small and medium enterprises requiring basic endpoint data leakage prevention.
PrivateDLP (Pro Edition): Advanced enterprise subscription that fully inherits all Standard Edition functions, supplemented by full USB file audit, AI-powered behavior analysis, intelligent violation detection, and flexible customized deployment capabilities. Designed for medium-to-large enterprises pursuing precise security auditing, employee productivity optimization, and private data sovereignty.
Both editions support unified web console management, batch and individual device policy delivery, and real-time endpoint data synchronization to the enterprise server.
2. Full Included Features by Subscription Tier
2.1 USB Disk Security (Standard Edition) Core Features
All standard subscription licenses include comprehensive foundational endpoint protection and behavior control functions, fully configurable via the centralized web management console:
USB Antivirus Protection: Provides real-time USB device defense, manual and automatic virus scanning, and dedicated quarantine areas for infected files to block malware spread via portable storage devices.
Fine-Grained USB Device Control: Supports disabling USB data copy, full USB access prohibition, blocking all external USB device connections, and configuring trusted USB peripheral whitelists to prevent unauthorized data exfiltration.
Network & Application Control: Enables browser website management via customizable URL whitelists and blacklists, blocks startup of blacklisted applications, and restricts specified programs from accessing the network to standardize employee office network behaviors.
2.2 PrivateDLP (Pro Edition) Exclusive Advanced Features
PrivateDLP Pro includes 100% of Standard Edition capabilities plus two core exclusive modules for full audit visibility and intelligent security governance, solving the detection blind spots of traditional rule-based DLP systems:
Complete USB File Transfer Auditing & Smart Alerting: Automatically records all file copy behaviors between local endpoints and USB devices, including filenames, file types, and copy timestamps. Administrators can configure alert rules for sensitive files or specified file types to trigger real-time notifications for abnormal data export behaviors.
Privacy-First AI Behavior Audit & Productivity Analytics: Empowers administrators to define work behaviors and entertainment behaviors through natural language without complex coding. The system captures endpoint screenshots approximately every 60 seconds and performs content classification via LLM (default Gemini model) to automatically calculate employee working time, offline idle time, and entertainment time. All routine screenshots are permanently deleted immediately after analysis to protect employee privacy. Only confirmed violation screenshots are retained as evidence, effectively identifying hidden data leakage behaviors such as unauthorized uploads to unknown personal cloud disks that traditional rigid DLP rules cannot detect.
2.3 Enterprise Customizable Exclusive Capabilities (PrivateDLP Only)
PrivateDLP Pro supports personalized customization for enterprise commercial customers to meet data sovereignty, compliance, and private deployment requirements:
Custom Evidence Storage Strategy: All violation alert screenshots and audit evidence can be stored in our official secure cloud storage or independently designated enterprise storage, supporting all S3-compatible storage, Azure Blob, and on-premises private storage servers to achieve full data control by enterprises.
Flexible Multi-LLM Adaptation & Private Inference: Enterprises can use the default Gemini model for AI analysis (screenshots will never be used for model training) or independently access third-party AI models including OpenAI and Claude. The solution also supports full on-premises deployment of self-hosted LLM models, ensuring all enterprise audit data and screenshot analysis procedures run inside the corporate intranet without external data leakage.
3. Subscription Purchase & Pricing Policy
3.1 USB Disk Security (Standard) Purchase Rules
Public Self-Service Purchase: Standard edition licenses are available for direct ordering and purchase via our official website, suitable for small-batch and conventional enterprise procurement.
Enterprise Bulk Discount & Exclusive Package: For enterprises purchasing large-scale license quantities, customized discount policies are available via business consultation. Qualified enterprise customers will receive the official pre-authorized MSI installation package, supporting silent batch deployment and automatic server activation without manual endpoint activation.
3.2 PrivateDLP (Pro) Purchase & Quotation Rules
PrivateDLP Pro adopts custom enterprise quotation instead of public fixed pricing, due to its highly flexible deployment and customizable architecture:
The subscription cost varies according to enterprise deployment demands, including public cloud AI analysis mode or private on-premises LLM deployment mode.
The official team provides one-on-one business communication to confirm customized functions, storage schemes, AI model deployment solutions, and enterprise scale, then delivers exclusive formal quotation and technical customization services.
All Pro edition trial and official packages (EXE and MSI) are provided through official business application and approval channels.
4. Subscription Value Differentiation
Standard Subscription: Cost-effective for basic terminal security management, focusing on blocking conventional USB and network data leakage risks, meeting daily safety supervision needs of small and medium-sized enterprises.
Pro Subscription: Enterprise-grade intelligent DLP solution that realizes full-trajectory data audit, hidden threat identification, employee productivity digital management, and compliant private deployment. It fills the functional defects of traditional DLP and adapts to high-standard security and compliance management scenarios for large enterprises and institutions.
5. Summary
Our two-tier subscription system covers full-scene endpoint data security demands from basic defense to intelligent audit. USB Disk Security provides standardized and cost-effective foundational protection with public transparent purchasing channels, while PrivateDLP delivers advanced AI-driven security, privacy-compliant monitoring, and highly customizable enterprise deployment solutions via customized enterprise subscription services. Enterprises can select matching subscription specifications according to organizational scale, data security level, compliance requirements, and deployment architecture to build a targeted endpoint data leakage prevention system.
