NETCENTER CLOUDLINK LTD. is a national high - tech enterprise, specializing in providing innovative community edge cloud and Internet of Things (IoT) intelligent solutions. Based on the concept of ZTNA (Zero - Trust Network Access), the company has constructed a unified, secure, professional and comprehensive intelligent solution for cloud, network, edge and end. It covers eight major functions including the IoT platform, edge computing, AI vision algorithms, data acquisition, etc., and is applied in fields such as smart factories, smart cities, and smart electricity utilization. In the field of remote PLC operation and maintenance, the company integrates ZTNA security technology to build a dynamic access control system. Combined with edge computing nodes, it realizes real - time data collection and local processing of equipment data, effectively reducing network latency while obtaining information of all factory equipment and conducting more effective maintenance. The company has developed a motor health prediction solution based on the training algorithm of the DeepSeek large - model. Through multi - dimensional data analysis, it can identify equipment failure risks in advance. In addition, NETCENTER CLOUDLINK LTD. has also launched a physical sentinel remote operation and maintenance solution that supports HDMI hardware direct connection and BIOS in - depth access, ensuring the purity and security of the operation and maintenance environment. As a leading enterprise in the Internet of Things industry, the new - generation ZTNA security network developed by NETCENTER CLOUDLINK LTD. has served more than 500 customers including Xinhua News Agency, CCTV, the Ministry of Public Security, Tencent, etc., significantly reducing the network risks and access latency of traditional VPNs. NETCENTER CLOUDLINK LTD. has reached strategic cooperation with Tsinghua University and Akamai to further expand its global business territory. With its excellent technical strength and service quality, the company has been recognized by hundreds of enterprises such as TCL, CATL, and water conservancy facilities.

PLC Remote Maintenance & Operations The integrated solution combines eight core capabilities: • PLC Remote Maintenance & Operations • IoT Platform (Internet of Things) • Edge Computing • AI Vision Algorithms • Data Acquisition **• Zero Trust Network Access (ZTNA)** • Automated Dashboards Generation • Multi-Device Integration (Smart Gateways / Industrial PCs / Software Gateways) Remote PLC Maintenance integrates ZTNA security networking technology to build a dynamic access control system, establishing unified security across cloud, network, edge, and endpoints with granular permission allocation and stable connectivity. Compared to traditional VPNs, this approach significantly reduces network risks by 70% and access latency by 50-60%. Why Is Zero Trust the Inevitable Trend?* 1. Market Adoption · By 2025, 60% of enterprises will phase out VPNs in favor of zero trust. · The zero trust market grows at an annual rate of 22.3%, far surpassing VPNs. 2. Enterprise Practices · Google’s BeyondCorp (zero trust) reduced its internal attack surface by 95% after fully replacing VPNs. · Microsoft Azure AD Zero Trust now serves over 300 million users with 90% lower failure rates than VPNs. 3. Policy Drivers · China’s Data Security Law mandates "separation of powers and domains," aligning with zero trust principles. PLC Remote Maintenance Combined with Edge Computing Nodes Enables real-time data collection and localized processing of all factory equipment information, facilitating more efficient maintenance and updates.

Motor HealthGuardian — A Motor Health Prediction Solution Powered by DeepSeek Large-Language Model Economic Impact of Motor Failures • Global Energy Consumption: Motors account for 70% of global electricity usage. • Equipment Demographics: Induction motors constitute over 90% of mechanical operation equipment. • Grid Load: Motor loads represent more than 60% of power grid demand.
