A buyer’s starting point

Secure employee AI use without losing the practical detail.

Compare the control point, evaluation path and practical fit for the employee AI problem in front of you.

Aona protects employee use of third-party AI tools on managed devices, including the prompt and upload path.

Aona AI

For employee AI security

Workforce AI Security at the moment of use rather than at the data store: a browser plugin for Chrome, Edge, Firefox and Safari plus a native endpoint app that intercepts ChatGPT, Copilot and Claude desktop, hard block with no user override, layout-preserving DOCX, XLSX and PDF redaction on upload, and real-time coaching at the prompt with a first signal within hours. SOC 2 Type II and a self-serve 30-day trial.

Best for: Any organisation whose employees use ChatGPT, Copilot, Claude or Gemini and that needs the prompt and the upload controlled on the device, not only the data classified where it rests.

SOC 2 Type II and a self-serve 30-day trial.
VaronisOrganisations whose first need is sensitive data and permissions governed where they rest, across Microsoft 365, Salesforce, Snowflake, AWS and on-premises stores.
Data security platform (NASDAQ: VRNS) centred on discovery, classification and permissions analytics for data at rest, with an AI module covering AI data discovery, posture, a runtime gateway and AI detection and response.
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).
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.
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. Bought by demo or through its AWS Marketplace listing, 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.

Aona inspects what reaches an AI tool. It does not discover or classify data at rest in SaaS, cloud or on-premises stores.
Aona is not an EDR, a cloud posture tool or a SOC platform. It adds dedicated controls for employee AI use.
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.
Aona has a SOC 2 Type II examination report. No FedRAMP, IRAP or ISO 27001 today.

Your questions

Varonis alternatives, answered.

Answers to help you build your shortlist.

What are the best Varonis alternatives in 2026?

Alternatives to Varonis for securing employee AI use include Aona AI, Microsoft Purview, Nightfall AI, Harmonic Security and Prompt Security. 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. Varonis governs data where it rests and in the sanctioned AI platforms it connects to through their APIs, which is where its control point stops for the prompt an employee types on a laptop.

Why is Aona AI a strong alternative to Varonis?

Varonis classifies and governs data where it rests and correlates it with permissions; Aona inspects what an employee sends to an AI tool at the moment of use. 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, with a first signal within hours of deployment. It exports to Microsoft Sentinel via OCSF, is SOC 2 Type II certified, and starts with a 30-day self-serve trial.

Where does Aona stop, compared with Varonis?

Scope, stated plainly: Aona inspects what reaches an AI tool. It does not discover or classify data at rest in SaaS, cloud or on-premises stores. Aona is not an EDR, a cloud posture tool or a SOC platform. It adds dedicated controls for employee AI use. 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. 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 Varonis 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. Varonis runs sales-led evaluations, typically through a data risk assessment, rather than a 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 Varonis if you also need sensitive data and permissions governed where they rest across Microsoft 365, Salesforce, Snowflake, AWS and on-premises stores, which Aona does not do. Varonis stops at the store and the connected platform: it governs data at rest and the sanctioned AI platforms it integrates with through their APIs, so a prompt typed into a consumer AI app or a desktop assistant on the employee's device is outside that control point until the data or the platform is connected.
