Prompt management, evaluation, and guardrails for production LLM apps
Build, test, and version prompts in a table-based editor that anyone comfortable with spreadsheets can use.
Add natural-language assertions, pattern matching, or custom code checks and run them over datasets to catch regressions.
Trace every request and response, inspect latency and cost, and diagnose why an LLM answered the way it did.
One-click AI Firewall blocks prompt injection, denial-of-service attempts, and information leaks with customisable content filtering and alerts.
Attack-led AI security testing and red teaming
Agent-native reconnaissance maps models, agents, tools, instructions, permissions and behaviours the way an attacker would before launching attacks.
Continuous, adaptive testing of AI agents and systems against evolving attack techniques, rather than one-off audits.
Findings are backed by a knowledge base built from more than 175 publicly disclosed AI vulnerabilities across major AI systems.
Runtime protections and remediation guidance help close defensive gaps and verify that fixes actually hold.
