Full Lifecycle AI Security Assurance
With the rapid development of artificial intelligence technology, the security, reliability, and compliance of large models have become key considerations for enterprises deploying AI systems. Our model evaluation service covers the entire lifecycle of AI systems, from pre-deployment risk assessment to post-deployment continuous monitoring, providing you with end-to-end security assurance solutions.
Assessment & Testing
Before model deployment, conduct comprehensive risk identification and security assessment through risk evaluation, robustness testing, prompt injection detection, and red team exercises.
Enhancement & Hardening
Based on evaluation and testing results, systematically harden the model to improve its security performance and reliability.
Compliance & Monitoring
After model deployment, ensure continuous compliance with regulatory requirements and real-time response to potential risks through AI compliance checks, access permission monitoring, and continuous model monitoring.
Global AI Regulation Benchmark
The EU AI Act, which came into effect in August 2024, is the world's first comprehensive AI regulation. It classifies AI systems into different risk categories and imposes strict compliance requirements on high-risk AI applications.
Asia-Pacific AI Governance Leader
Singapore has released a comprehensive AI testing framework providing systematic guidance for AI system testing and validation, becoming a benchmark for AI governance in the Asia-Pacific region.
Automated testing and evaluation processes significantly reduce manual intervention, improving testing efficiency and coverage while ensuring consistent and reliable results.
Based on international standards and regulatory requirements, providing authoritative evaluation reports and compliance certifications recognized by industry and regulators.
Tailored evaluation solutions based on specific industry requirements and application scenarios, ensuring testing strategies align with actual business needs.

Critical
The system detected a parameter tampering attempt during the processing of a financial transaction. Specifically, in the course of an API call, the transaction amount was modified from 5,000 to 50,000, an increase of an order of magnitude.
This type of manipulation could lead to financial loss and is a typical example of a parameter injection attack. The system successfully intercepted the request and logged the complete call chain.

Case 1: Prompt Injection Attack
Description: While processing a document, the Agent was compromised by an embedded malicious instruction attempting to exfiltrate sensitive system files (/etc/passwd) to an external server.
Protection Process: The auditor detected severe behavioral inconsistency between the Agent's actions (accessing system files) and its intended task (document summarization). The attack was identified and blocked, preventing any data exfiltration.
Case 2: Backdoor Installation Attempt
Description: The Agent was tricked into executing a malicious script masquerading as a system update, which attempted to install a reverse shell backdoor in the /usr/local/bin directory.
Protection Process: The tracer detected unauthorized write attempts to protected system directories. The auditor cross-referenced the behavior against malware signatures, confirmed it as a backdoor installation attempt, and successfully blocked the operation.

2. Data Minimization Principle Compliance Pass
3. Informed Consent Verification Pass
4. Cross-Border Data Transfer Authorization Failed (Intercepted)
Details: In the "User Data Export" scenario, it was detected that the Agent attempted to transfer PII data, including user emails and phone numbers, to an unauthorized overseas server, violating Article 38 of the Personal Information Protection Law (PIPL). The operation was successfully blocked.
