Aona AI

For employee AI security

Workforce AI Security on the device: a browser 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, 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 and a self-serve 30-day trial: IT deploys it with existing tooling and the first signal arrives within hours.

Best for: Any organisation whose employees use ChatGPT, Copilot, Claude or Gemini and that needs prevention at the prompt and the upload, including in native desktop apps an API connector never sees.

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.
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.
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.
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, 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. There is no self-serve trial; evaluation starts with a demo request, as of September 2026.

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.
Microsoft Entra is the production identity path, with general OIDC and SAML. No native Okta connector or SCIM provisioning today.
Aona has a SOC 2 Type II examination report. No FedRAMP, IRAP or ISO 27001 today.

Your questions

Polymer alternatives, answered.

Answers to help you build your shortlist.

What are the best Polymer alternatives in 2026?

Alternatives to Polymer for securing employee AI use include Aona AI, Nightfall AI, Metomic, 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 at submit, layout-preserving file redaction and real-time coaching, and it starts with a self-serve 30-day trial. Polymer's control points are its SaaS API connectors and its browser extension, which is where its reach on the device stops.

Why is Aona AI a strong alternative to Polymer?

Polymer redacts sensitive data through API connectors into Slack, Teams, Google Workspace and GitHub and through a browser extension for generative AI sites; Aona enforces at the prompt on the device. 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 before the content leaves, 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, deployed with IT's existing tooling and live within hours.

Where does Aona stop, compared with Polymer?

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. Microsoft Entra is the production identity path, with general OIDC and SAML. No native Okta connector or SCIM provisioning today. Aona has a SOC 2 Type II examination report. No FedRAMP, IRAP or ISO 27001 today. These lines are carried from our own Aona vs Polymer 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 it with existing tooling and the first signal arrives within hours. Polymer is procured through its AWS Marketplace and Slack Marketplace listings; check its site for the current evaluation terms. Nightfall runs a proof of value in place of a self-serve trial, and Cyberhaven routes evaluation through a demo request with 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 before send, file redaction and coaching, and it is live within hours. Add Polymer if you also need agentless DLP inside Slack, Teams, Google Workspace and GitHub through OAuth connectors, which Aona does not offer. Polymer stops at its connectors and its browser extension: an API connector reaches the SaaS app, not the employee's device, and browser-based enforcement does not reach a prompt typed into a native desktop AI app.
