AI security has moved beyond prompt filtering.
AI systems now call tools, retrieve data, persist instructions, execute workflows, and act across enterprise systems. Compare VANGUARD with leading platforms to see where governed AI execution begins.
Runtime governance and agent integrity
Controls trusted instructions, context access, tool execution, and audit evidence once AI systems start taking action.
Lakera / Prompt Shields
Protect prompts, documents, and model interactions before or during generation.
Portkey
Routes traffic, manages providers, and gives engineering teams observability and fallback.
Protect AI
Secures models, datasets, registries, pipelines, and enterprise AI asset posture.
Gray Swan / Akto
Finds adversarial weaknesses and agentic exposure before the production runtime takes over.
Most AI security tools solve a different layer.
VANGUARD focuses on runtime governance: what an AI system is allowed to do, in this context, for this tenant, with this tool, using this instruction.
Prompt and content protection
Detecting prompt injections, jailbreaks, unsafe content, and data leakage before they influence model behaviour.
Gateway infrastructure
Routing model traffic, observing requests, managing providers, and controlling cost and reliability.
AI/ML lifecycle security
Securing models, datasets, pipelines, registries, and AI assets across the broader MLSecOps estate.
Red teaming and evaluation
Discovering how models and agentic systems can be manipulated before or outside production runtime.
Where VANGUARD fits.
Govern actions, not just prompts.
Secure MCP and tool-calling workflows
VANGUARD mediates API access, tool execution, retrieved context, and runtime workflow decisions with tenant-aware policies.
Control stateful AI risk
Agentic threats often emerge across memory, retrieved content, tool output, and multi-step execution rather than one turn at a time.
Preserve instruction provenance
Determine whether an instruction came from a trusted user, policy, retrieved document, memory artefact, or untrusted source.
Produce governance evidence
Turn AI governance into enforceable runtime controls with records that support audits, assurance reviews, and internal policy checks.
