Advantages

Comprehensive Behavior Logs

The system automatically identifies thousands of network applications, covering video streaming, P2P downloads, email transfers, social networks, e-commerce, instant messaging, online games, remote control, and more. It supports the highest number and variety of application protocols in the industry. By accurately recognizing network protocols, it detects and records inappropriate content such as harmful speech, violence, drugs, pornography, and non-work-related applications like online games, effectively preventing sensitive information leaks and unauthorized activities.

Strict Internet Behavior Management

The system optimizes bandwidth management to enhance user experience, regulates network application access to boost productivity, and enforces role-based access control. It proactively prevents data breaches through a three-tiered approach: preemptive prevention, real-time interception, and post-incident investigation. By filtering harmful content, it mitigates regulatory and legal risks while meeting compliance audits, thereby minimizing reputational damage from public opinion.

Detailed Analysis of Encrypted Traffic

The system utilizes encrypted traffic analysis technology with network encryption protocol parsing capabilities, enabling precise analysis and security auditing of HTTPS-encrypted traffic. By deeply mining critical data within encrypted traffic, it effectively meets users' needs for fine-grained control over encrypted traffic. This provides stable and reliable technical support for organizational cybersecurity audits, helping organizations prevent potential security risks lurking behind encrypted traffic.

Accurately Identify Sensitive Information

The system employs deep conversation reconstruction technology to analyze conversation flows in detail, enabling the restoration and parsing of files transmitted via email, HTTP, FTP, and other applications. It detects sensitive information in documents, images, and compressed files, accurately identifies non-compliant content, and triggers alerts to effectively prevent the unauthorized transmission of sensitive information over the network.

Applications

Scenario

Bypass deployment for monitoring image traffic is the most widely adopted method for such products, featuring a simple workflow: simply connect the system's monitoring port to the switch's mirror port to complete deployment and activation. This approach not only ensures high deployment efficiency but also requires no modifications to the existing network architecture.

Issues Resolve

Safe and stable operation.
Applicable to small and medium network environments without altering the network structure.
The audit content is fine, which is convenient for post-tracing and tracing.

Scenario

In specialized business scenarios like cloud platforms, network traffic in such environments cannot be captured through standard port mirroring, creating audit blind spots for related operations. To address this, deploying an Agent component on application servers enables the transmission of business traffic back to the system, allowing for the analysis and auditing of network operations.

Issues Resolve

It addresses scenarios where virtualization and cloud platforms cannot mirror traffic for auditing purposes.
Monitor host resource usage and adjust startup/shutdown based on preset thresholds.
Encrypt and compress traffic for secure and efficient transmission.

Scenario

The system supports both transparent inline deployment via virtual lines and logical inline deployment with forward/reverse proxies, enabling direct network traffic monitoring and analysis. It also features link aggregation and redundancy backup mechanisms to ensure uninterrupted service operation, making it ideal for core network areas with stringent security and stability requirements.

Issues Resolve

Enhance encryption traffic monitoring and behavior control capabilities.
Deploying with reverse proxy effectively hides the real target server and reduces exposure.

Scenario

This solution is primarily designed for group enterprises with a headquarters-branch structure, where both headquarters and branches require audit capabilities. The headquarters utilizes high-performance network audit systems as central management hubs, while branches deploy appropriately scaled network audit systems as subordinate nodes based on their needs. This centralized management model enables unified control over branch operations, effectively addressing the challenge of dispersed monitoring points.

Issues Resolve

The headquarters management center oversees unified policy distribution and log collection/analysis, ensuring policy consistency.
Branch nodes can either uniformly receive control rules from their parent nodes or establish customized policies tailored to their specific business scenarios and threats, enabling autonomous decision-making.
This system reduces the headquarters' administrative workload while consolidating and analyzing branch node logs for routine monitoring and response capabilities.

Value to Customers

Strengthen Data Security Controls

Enhance the ability to trace business access behaviors, helping customers centrally manage internet access logs, promptly identify security risks, strengthen network security protection, and optimize network resource allocation.

Meet Compliance Requirements

We help enterprises establish comprehensive protection measures and ensure network operators comply with security audit requirements under relevant policies and regulations, thereby enhancing their cybersecurity capabilities and guaranteeing stable network operations.

Flexible Deployment for Various Scenarios

Bypass deployment is the primary deployment method, while also supporting tandem and distributed deployment modes. With flexible deployment capabilities, the system adapts to diverse network environments and fulfills audit requirements across various scenarios.

Success Case

Network audit project of a provincial expressway group

Audit strategies need to be enabled for toll booth and sub-center devices. Toll booths do not keep audit data locally, and data is uploaded to each sub-center for retention. In this way, upper-level devices can manage lower-level devices in a centralized manner. Audit data and alarm data are uploaded to the provincial center for unified retention in real time.

Value to Customers：: Stable and reliable system Comprehensive and detailed audits Easy investigation and personnel accountable identification
