Comparison — Runtime-only guardrail tools

XAIGuard vs Lakera

Lakera is best known for real-time detection of prompt injection and jailbreaks, delivered as a developer-friendly API with strong research behind it. XAIGuard covers the same request path but treats it as one of four layers alongside data posture, agent governance and audit evidence.

Honest read

Where each product is strongest.

Where XAIGuard wins

  • Four layers, one policy model

    Runtime guardrails, AI data posture, agent and MCP governance, and compliance evidence share one policy engine and one audit trail.

  • Deployment for non-developer traffic

    PAC file, browser shield and API proxy cover staff using SaaS AI tools, not only traffic that a developer routes through an SDK.

  • Evidence an auditor accepts

    Signed, hash-linked decision records mapped to OWASP LLM Top 10, NIST AI RMF, ISO/IEC 42001 and EU AI Act obligations.

  • Shadow-AI discovery

    Proxy, firewall and CASB log ingestion builds an inventory of AI usage the security team never approved.

Where Lakera wins

  • Deep, focused injection research

    Lakera's detection models are built on a large adversarial dataset gathered from public red-team games, and injection detection is their primary research investment.

  • Very fast developer integration

    A small API surface means a team can add guardrails to an application in an afternoon without adopting a platform.

  • Low operational footprint

    No enterprise rollout programme required — attractive for engineering teams that want protection without a security-org project.

  • Strong choice for a single AI product

    If you ship one LLM application and need best-in-class injection filtering, a focused guardrail is a reasonable and cheaper answer.

FAQ

XAIGuard and Lakera, asked plainly.

Is XAIGuard's injection detection as good as a specialist's?

We publish our own adversarial pass-rate rather than asking you to take it on trust, and a technical walkthrough runs both against your own prompts. Judge it on your traffic, not on our marketing.

Can we run both?

Yes. Some teams keep a specialist detector inside one product and use XAIGuard for organisation-wide coverage, agent governance and evidence.

What if we only have one AI application?

Then a focused guardrail may be enough. XAIGuard earns its place when you have multiple applications, staff using SaaS AI tools, or an audit obligation.

Next step

Evaluate both against your own traffic.
