The best Lakera alternatives, ranked

A ranked list of real, publicly known options for the Workforce AI Security use case. Aona AI leads for teams whose real risk is employee AI use rather than the LLM features they build. Every vendor below is a genuine product you can evaluate.

1

Aona AI

Our pick

Workforce AI Security at the browser and endpoint layer: shadow AI discovery, real-time coaching, DLP for AI tools, governance, and AI upskilling. SOC 2 Type II, 92.9% AI classification accuracy.

Best for: Teams whose AI risk is employees using ChatGPT, Copilot and other AI tools, not the LLM features they build, and who want a self-serve 30-day trial.

2

Lakera

Application-side LLM security with Lakera Guard: prompt-injection and jailbreak detection with public, research-grade benchmarks (Gandalf dataset), plus a newer Workforce module.

Best for: Teams building AI features into their own product who need to protect LLM calls and agent runtime in the application.

3

Prompt Security

Broad GenAI security platform spanning workforce AI, an LLM firewall, and agent runtime controls for application AI security.

Best for: Organisations that need both workforce AND application AI security from a single vendor.

4

Harmonic Security

Generative AI governance via a lightweight browser extension and desktop client, nudging users toward safer behaviour across ChatGPT, Gemini, Perplexity and many AI surfaces.

Best for: US-centric enterprises that want a browser-extension data-protection layer for AI use.

5

WitnessAI

Network-layer AI security and governance that observes AI traffic and applies policy at the network, with identity-aware visibility.

Best for: Large enterprises whose AI risk is mostly browser traffic at scale across a managed network.

6

Microsoft Purview

Microsoft's data security and compliance suite, with DLP and insider-risk controls that extend to Copilot and some AI scenarios inside the Microsoft estate.

Best for: Microsoft-365-centric enterprises standardising on the Purview compliance stack.

Where Aona is weaker

We carry these caveats verbatim from our own Aona vs Lakera comparison. An honest alternatives list has to include where the leader falls short.

  • !No application-side LLM firewall. If you are building AI features into your product, Aona does not protect your LLM calls. Lakera Guard does.
  • !No prompt-injection or jailbreak benchmarks. Lakera ships research-grade detectors with public benchmarks (Gandalf dataset, multilingual coverage). Aona's classifiers are not benchmarked at that level.
  • !No application-side agent runtime protection. Aona's native endpoint app inspects agents on the employee machine (process, network, MCP); Lakera secures agent runtime inside the app you build, which Aona does not cover.
  • !No SDK or deep observability integrations (Grafana, Splunk). Lakera ships these for application-side telemetry.
