Aona AI

For employee AI security

Workforce AI Security for the employee-to-AI surface: a browser plugin for Chrome, Edge, Firefox and Safari plus a native endpoint app that inspects prompts to ChatGPT, Copilot and Claude desktop at submit, hard block with no user override, layout-preserving DOCX, XLSX and PDF redaction on upload, real-time coaching, and AI policy templates for the EU AI Act, ISO 42001 and SOC 2. SOC 2 Type II, self-serve 30-day trial, deployed with IT's existing tooling, first signal within hours.

Best for: Any organisation whose employees use ChatGPT, Copilot, Claude or Gemini and that needs the prompt and the upload governed and coached, alongside whatever it runs for malware and the SOC.

CrowdStrike FalconOrganisations buying endpoint threat detection, SOC automation and cloud posture from one platform.
Endpoint detection and response platform with Charlotte AI for SOC triage and Falcon Cloud Security for cloud AI posture, sold as a platform subscription.
Harmonic SecurityOrganisations that want prompt-text redaction and nudges across browsers and desktop AI clients, bought by demo or through AWS Marketplace.
Browser extension plus a desktop client (Claude Desktop, ChatGPT Desktop, Cursor, Codex, Claude Code, GitHub Copilot, Ollama) with real-time prompt redaction and an MCP gateway. Packaged as three tiers (Explore, Guide, Command), demo-led, with no self-serve trial as of September 2026.
WitnessAIOrganisations that want AI controls applied in a network path they already route traffic through.
Network-based AI security and governance that observes and controls AI traffic without browser extensions or endpoint clients; desktop AI apps are covered when their traffic is routed through it. An Instant Demo product tour stands in for a self-serve trial, as of September 2026.
Prompt SecurityOrganisations that want employee and application AI security bought together through the SentinelOne Singularity platform.
GenAI security platform from SentinelOne, built into the Singularity platform: employee AI controls with anonymisation and coaching, an LLM firewall for applications, and an AI endpoint agent for local LLMs and MCP servers (February 2026). Sold by demo, with no self-serve trial as of September 2026.
Microsoft PurviewMicrosoft 365 estates that want Copilot and Microsoft 365 data governed inside the Purview licensing model.
Microsoft's data security and compliance suite. Its AI controls run in the browser (the Purview extension is required for Chrome endpoint DLP on Windows), prompt and response visibility for third-party AI sites requires E5-class licensing plus pay-as-you-go billing, and locally installed AI apps are reached through a network data security path (Entra Global Secure Access or a SASE partner, partly in preview).

Aona is not an EDR, a cloud posture tool or a SOC platform. It adds dedicated controls for employee AI use.
Aona has no SOC orchestration layer: no triage, investigation or threat-hunting queue of its own. Its events go to Microsoft Sentinel via OCSF, a REST API and webhooks.
Aona has a SOC 2 Type II examination report. No FedRAMP, IRAP or ISO 27001 today.
No iOS or Android coverage: AI use on phones is out of scope.
AI agent and MCP inspection ships in limited rollout on the native endpoint app, not general availability.

Your questions

CrowdStrike alternatives, answered.

Answers to help you build your shortlist.

What are the best CrowdStrike alternatives in 2026?

If your goal is securing employee AI use rather than endpoint malware defence, alternatives to CrowdStrike are Aona AI, Harmonic Security, WitnessAI, Prompt Security and Microsoft Purview. Aona AI is built for securing employee AI use: it inspects the prompt and the upload on the device, in the browser and in ChatGPT, Copilot and Claude desktop apps, with hard block, layout-preserving file redaction, AI policy templates and real-time coaching, and it starts with a self-serve 30-day trial. CrowdStrike Falcon is built around threat detection and response on the endpoint and in the cloud; governing what an employee types into an AI tool, with coaching and AI policy templates, is a different product category, which is where this list picks up.

Is Aona AI a real alternative to CrowdStrike?

For securing employee AI use, yes. CrowdStrike Falcon detects and responds to threats on the endpoint and in the cloud; Aona governs what employees send to AI tools. Aona's browser plugin and native endpoint app inspect the prompt at submit in Chrome, Edge, Firefox and Safari and in ChatGPT, Copilot and Claude desktop apps, block hard with no user override, redact DOCX, XLSX and PDF uploads with the layout intact, coach the employee in real time, and export to Microsoft Sentinel via OCSF. They solve different problems, so run Falcon for malware and the SOC and add Aona for the prompt and the upload. Aona is SOC 2 Type II certified, with a 30-day self-serve trial and a first signal within hours.

Where does Aona stop, compared with CrowdStrike?

Scope, stated plainly: Aona is not an EDR, a cloud posture tool or a SOC platform. It adds dedicated controls for employee AI use. Aona has no SOC orchestration layer: no triage, investigation or threat-hunting queue of its own. Its events go to Microsoft Sentinel via OCSF, a REST API and webhooks. Aona has a SOC 2 Type II examination report. No FedRAMP, IRAP or ISO 27001 today. No iOS or Android coverage: AI use on phones is out of scope. AI agent and MCP inspection ships in limited rollout on the native endpoint app, not general availability. These lines are carried from our own Aona vs CrowdStrike comparison, so you can evaluate with eyes open.

Is there a free trial to evaluate these alternatives?

Aona offers a 30-day self-serve free trial covering AI adoption analytics, shadow AI discovery, security and compliance monitoring and real-time employee coaching; it deploys with IT's existing tooling and shows a first signal within hours. The other vendors' evaluation paths differ: CrowdStrike's 15-day free trial is the general Falcon platform trial, WitnessAI offers an Instant Demo product tour rather than a trial, Harmonic Security is demo-led, and Prompt Security is sold by demo through SentinelOne, as of September 2026.

How do I choose between these vendors?

Start with Aona for employee AI use: it governs the prompt and the upload on the device, in the browser and in native desktop AI apps, with hard block, file redaction, AI policy templates and coaching, and it is live within hours. Keep CrowdStrike for endpoint detection and response, SOC automation with Charlotte AI and cloud posture with Falcon Cloud Security, and add Aona beside it. Where Falcon stops for this use case: AI policy templates for the EU AI Act and ISO 42001, real-time coaching at the prompt and layout-preserving redaction of DOCX, XLSX and PDF uploads to AI tools are not part of its documented product.
