Net3 Shield
The security layer between your AI and the people attacking it.
AI applications face a new class of threats: prompt injection, jailbreaks, data exfiltration through model outputs, and misuse that traditional security tools never see. Net3 Shield sits in front of your models and inspects every prompt and every response.
Shield enforces your AI policies in real time — blocking attacks, redacting sensitive data, moderating outputs, and logging everything for compliance — without adding meaningful latency to your application.
What Net3 Shield does.
Prompt injection protection
Detect and block direct and indirect injection attempts before they reach the model.
Jailbreak detection
Identify adversarial prompts designed to bypass model guardrails and system instructions.
Sensitive data protection
Detect and redact PII, credentials, and confidential data in prompts and responses.
AI policy enforcement
Define what your AI may and may not do — Shield enforces it on every request.
Output moderation
Screen model responses for unsafe, off-brand, or non-compliant content before delivery.
Threat detection & logging
Real-time threat feeds, anomaly detection, and compliance-grade audit logs.
Where teams deploy it.
Customer-facing chatbots
Stop injection and jailbreak attempts from users interacting with public AI.
Banking & healthcare AI
Keep regulated data out of prompts and model outputs, with full audit trails.
Internal copilots
Prevent employees from leaking confidential data into third-party models.
Agent fleets
Apply one security policy across thousands of autonomous agents and workflows.
Stronger as one stack.
Net3 Shield integrates natively with the rest of the Net3 platform.
