Complete AI Reliability & Safety Pipeline
From development to production - evaluate, secure, and monitor your AI agents at every stage.
One-line Integration
Embed runtime guardrails and evaluation hooks into your development workflow with a single line of code.
Development
Automated Testing
Simulate real-world scenarios and integrate evaluations into CI/CD to catch regressions and risky behavior before deployment.
CI/CD
Live Monitoring
Continuously evaluate outputs, detect anomalies, and respond instantly to prompt injections or behavioral drift in production.
Production
Comprehensive AI Reliability & Safety Coverage
Ensure your AI systems remain consistent, compliant, and secure - across every interaction and deployment stage.
Guard Against Prompt Injections
Detect and neutralize prompt injection attempts that could alter instructions, exfiltrate data, or manipulate agent behavior.
Protect Sensitive Information
Automatically identify and redact PII, credentials, or confidential data in requests and responses - before they leave your boundary.
Moderate Content
Filter user inputs and agent responses for harmful, inappropriate, or policy-violating content—protecting users and your brand reputation.
Prevent Tool Misuse
Track and control tool invocation to stop unauthorized actions, data exfiltration, or unsafe command execution.
Detect Behavioral Drift
Identify when AI agents stray from their intended purpose, produce unreliable outputs, or respond off-topic to user queries.
Continuously Monitor & Evaluate
Measure reliability and performance in real time with ongoing evaluation of agent behavior, safety triggers, and response quality.
Built for Enterprise Teams
Enable secure, compliant, and reliable AI operations - tailored to your organization’s needs.
Flexible Deployment
Run HaliosAI on-prem, in your private cloud, or in hybrid environments to meet your security and data requirements.
Custom Guardrails & Integrations
Define organization-specific policies, connect with SOAR tools, and integrate with compliance platforms to enforce safe and consistent AI behavior.
Operational Confidence
Monitor and evaluate agent behavior continuously, with options for logging, reporting, and proactive insights - so you can stay in control at scale.
Simple, Transparent Usage Based Pricing
Start free and scale as you grow. No hidden fees, no surprises.
Free Trial
Explore all features and evaluate worry - free for 30 days.
- 5,000 free credits (≈ guardrail evaluations for early testing)
- Full feature access
- Community support
Developer Pro
For developers and teams running agents in production.
- Usage-based billing at $0.001 per credit
- $10 monthly minimum, applied toward usage
- Pay only for what you use - no commitments
- Priority support
Enterprise
For organizations needing tailored deployments and integrations.
- All Pro features
