Aona AI

For employee AI security

Workforce AI Security that reaches past the browser: a plugin for Chrome, Edge, Firefox and Safari plus a native endpoint app that intercepts ChatGPT, Copilot and Claude desktop, hard block at submit with no user override path, layout-preserving DOCX, XLSX and PDF redaction on upload, AI policy templates for the EU AI Act and ISO 42001, and a choice of seven Aona-managed hosting regions. 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 same policy enforced in native desktop apps as in the browser, with no route for the user to override a block.

MetomicOrganisations whose first need is sensitive data at rest inside SaaS apps, with browser AI use governed by the same policies.
SaaS-side DLP with agentless API connectors (Slack, Microsoft 365, Google Drive, Notion, Atlassian, Zendesk, Salesforce, Box, Dropbox), a browser extension covering ChatGPT, Claude, Copilot and Gemini that can block, coach, allow or route a request for approval, and an agent gateway for MCP traffic. No endpoint agent; US and EU hosting.
Nightfall AIOrganisations whose first need is DLP across SaaS data at rest, with AI uploads governed by the same detectors.
DLP platform with SaaS API connectors (Slack, Microsoft 365, Google Drive, Salesforce), a browser extension (Chrome, Edge, Arc, Brave, Vivaldi, Comet), macOS and Windows endpoint agents installed via MDM, and an MCP Gateway in early access (September 2026). Data is stored in the United States, and evaluation runs as a proof of value rather than a self-serve trial.
PolymerOrganisations whose first need is DLP inside SaaS collaboration apps, with browser AI sites covered through the extension.
Agentless, API-integrated DLP for SaaS collaboration apps (Slack, Teams, Google Workspace, GitHub) plus a browser extension for generative AI sites such as ChatGPT, with NLP-based redaction and AWS Marketplace and Slack Marketplace listings; a self-serve trial is not documented.
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).
CyberhavenOrganisations that want AI use governed as one flow inside a lineage-based endpoint DLP and insider-risk platform.
Data detection and response built on data lineage, with an endpoint agent, a standalone browser extension (May 2026) and block, warn or redact actions at the prompt and response level for AI tools. Flow, its AI-native data security product, was announced in July 2026 for release in the following quarter. No self-serve trial is stated; evaluation is sales-led, as of September 2026.

Read the full Aona vs Metomic comparison →

Aona has no API connectors for Slack, Drive, M365 or Salesforce content at rest. Its control point is the AI prompt and upload.
Coverage needs the Aona plugin or endpoint app on the device. There is no agentless or network-only mode, so personal and unmanaged devices are out of scope.
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

Metomic alternatives, answered.

Answers to help you build your shortlist.

What are the best Metomic alternatives in 2026?

Alternatives to Metomic for securing employee AI use include Aona AI, Nightfall AI, Polymer, Microsoft Purview and Cyberhaven. 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 and real-time coaching, and it starts with a self-serve 30-day trial. Metomic's AI controls live in its browser extension and its agent gateway, with no endpoint agent, which is where its reach on the device stops.

Why is Aona AI a strong alternative to Metomic?

Metomic scans SaaS data at rest through API connectors and governs browser AI use, ChatGPT, Claude, Copilot and Gemini, through an extension that can block, coach, allow or route a request for approval; Aona adds the native desktop surface and removes the override path. 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, and coach the employee in real time. It ships EU AI Act and ISO 42001 policy templates, a choice of seven Aona-managed hosting regions, Microsoft Sentinel export via OCSF, and a 30-day self-serve trial with a first signal within hours.

Where does Aona stop, compared with Metomic?

Scope, stated plainly: Aona has no API connectors for Slack, Drive, M365 or Salesforce content at rest. Its control point is the AI prompt and upload. Coverage needs the Aona plugin or endpoint app on the device. There is no agentless or network-only mode, so personal and unmanaged devices are out of scope. 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 Metomic 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 on this list are demo-led: Metomic's site routes to a Book a demo request, Nightfall runs a proof of value in place of a self-serve trial, and Cyberhaven states no self-serve trial, as of September 2026.

How do I choose between these AI security 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 and coaching, and it is live within hours. Add Metomic if you also need sensitive data found at rest inside Slack, Microsoft 365, Google Drive, Notion, Atlassian, Zendesk, Salesforce, Box and Dropbox through API connectors, which Aona does not do. Metomic stops at the browser and the API: with no endpoint agent, a prompt typed into ChatGPT, Copilot or Claude desktop apps is outside its extension's reach.
