The best Zscaler alternatives, ranked

A ranked list of real, publicly known alternatives for AI security. Aona AI leads for regulated mid-market teams that want endpoint-level visibility and real-time coaching. 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: Regulated mid-market teams that want endpoint-level visibility, in-the-moment coaching, and a self-serve 30-day trial.

2

Zscaler

Network-level security service edge (SSE) that blocks unsanctioned AI apps at the edge for traffic flowing through the managed network.

Best for: Large enterprises that already run Zscaler and want network-level blocking of unsanctioned AI traffic on managed networks.

3

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 instead of hard-blocking.

Best for: US-centric enterprises that want a browser-extension data-protection layer rather than network-edge blocking.

4

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.

5

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 365 estate.

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

6

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.

Where Aona is weaker

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

  • !No network-level blocking. Zscaler does this at the edge; Aona does not.
  • !Endpoint-required: no Shadow AI visibility on devices we are not deployed to (no BYOD, no mobile).
  • !macOS at enterprise scale needs manual install today (Intune is Windows-only for the native endpoint).
