Large Language Model Security

Background

With the rapid evolution of artificial intelligence, core innovations like large models, generative AI, and AI agents have deeply permeated diverse sectors—including government, finance, and enterprise operations—becoming the primary engines driving digital transformation and the high-quality development of the digital economy. However, the widespread proliferation of AI technologies has introduced unprecedented security challenges. Advanced threats such as adversarial attacks, model theft, data poisoning, and the exfiltration of sensitive training data continue to intensify. Furthermore, attack methodologies are growing increasingly intelligent, covert, and commercialized. These risks not only directly compromise corporate commercial interests and personal data security, but also severely imperil national security. Consequently, establishing a comprehensive, full-chain, and systematic AI security assurance framework—while strengthening the coordinated linkage across technical defenses, compliance standards, and regulatory governance—has become a fundamental prerequisite and critical enabler for the healthy, sustainable development of the artificial intelligence industry.

Solution

Leveraging decades of deep-rooted expertise in cybersecurity and forward-looking research in AI security, Topsec has developed a mature and comprehensive "1+3+X" Large Model Application Security Protection Solution. This framework establishes systematic security defenses that seamlessly cover the entire operational workflow across large model training, deployment, and inference.

The solution centers on a Large Model Security Operations Center (SOC) as its core hub to orchestrate global security capabilities. It coordinates asset and policy management, drives continuous monitoring, analyzes and validates risks, automates global policy orchestration, and conducts root-cause analysis to deliver integrated, enterprise-wide security operations.
The solution builds a solid foundation upon three core security pillars： Risk Monitoring, Delivers 24/7 monitoring of large model systems and operating environments, deeply analyzing model behavioral flows to accurately identify hidden vulnerabilities and non-compliant anomalies; Security Protection, Actively defends against internal and external threats like prompt injection, data poisoning, and internal privilege abuse, comprehensively safeguarding the intrinsic security and stable operation of the models; Incident Response, Accelerates threat analysis and judgment, root-cause analysis, and closed-loop remediation to minimize risk exposure and drastically reduce business impact.
This core capability is complemented by X standardized, hierarchical protection layers, providing multi-dimensional general security defenses across networks, systems, applications, data, and endpoints. Layered with specialized, model-specific protection capabilities, it satisfies comprehensive security requirements across all scenarios—including model-native architectures, interactive API invocations, the full data lifecycle, and underlying infrastructure environments.
Furthermore, Topsec continuously drives product and technology innovation. The company has launched products including large model multi-modal security gateways, large model data security monitoring systems, large model security evaluation platforms, and API security auditing solutions. Delivering end-to-end security control over large models and AI agents, this comprehensive solution has been successfully deployed and production-proven across critical sectors such as government, finance, energy, and healthcare.

Value to Customers

Precise and Controllable Large Model Output Security

Built on mature large model security standards, this capability establishes a multi-layered output control framework. By leveraging deep semantic understanding, multi-dimensional content inspection, and dynamic risk filtering technologies, it delivers real-time, granular control over model-generated content. This effectively mitigates risks such as toxic content generation, sensitive data exfiltration, and intellectual property infringement, safeguarding the secure and stable operation of large model applications.

Full-Lifecycle Systematic Threat Defense

Addressing emerging intelligent threats—such as AI-driven malicious scrapers, adversarial attacks, model theft, and data poisoning—and overcoming the industry pain point of failed traditional point defenses, the solution adopts the systematic "1+3+X" architectural framework. It builds a defense-in-depth capability covering the entire lifecycle across data collection, model training, model deployment, and inference services, comprehensively safeguarding core model data and assets.

Efficient and Intelligent Integrated Security Operations

Leveraging the Large Model Security Operations Center (SOC) to establish a unified central administration hub, the platform integrates core capabilities including full-lifecycle asset management, continuous real-time monitoring, AI-driven threat analysis and judgment, automated policy orchestration, and end-to-end root cause analysis. This delivers centralized management and closed-loop remediation of large model security risks, significantly improving security operations efficiency while minimizing the business impact of security incidents.
