The verdict

The Aona advantage

Aona is the pick for employee AI use: a 30-day guided trial, hard-block DLP on prompts and files with no user override, layout-preserving DOCX, XLSX and PDF redaction, native ChatGPT, Copilot and Claude desktop app coverage and seven Aona-managed hosting regions, with a first signal during the agreed evaluation. Prompt Security is for the application side, the LLM firewall and agent guardrails for AI you build into your own product, and since the 2025 acquisition it is sold through SentinelOne's Singularity platform with no self-serve trial and no documented residency choice, so its employee module is bought and evaluated on the platform's terms.

About this comparison

Aona is built for one problem, employees' use of AI tools, and ships the controls that problem needs: hard-block DLP on prompts and uploads with no user override, layout-preserving DOCX, XLSX and PDF redaction, native desktop app coverage for ChatGPT, Copilot and Claude, real-time coaching, seven Aona-managed hosting regions and a 30-day guided trial. Prompt Security, sold as Prompt Security from SentinelOne and built into the Singularity platform since the 2025 acquisition, covers application-side LLM firewalls and agent guardrails alongside an employee module; buying it means a demo request through the Singularity sales motion, with no self-serve trial.

The Workforce AI Security platform for any company adopting generative AI, with broader endpoint coverage than the incumbents, a simpler trial, and one of the few that ships hard-block DLP for AI prompts and files.

Prompt Security (SentinelOne): AI security platform sold as Prompt Security from SentinelOne since the 2025 acquisition: application-side LLM firewall, agent guardrails and an employee usage module, built into the Singularity platform.

What the SentinelOne acquisition changesAcquisition facts verified July 2026, product packaging re-checked September 2026

SentinelOne announced an agreement to acquire Prompt Security on 5 August 2025 and completed the deal on 5 September 2025, at a price reported between USD 180 and 250 million.
SentinelOne has integrated Prompt Security's GenAI and AI-agent security technology into its Singularity platform, and the product is now sold through that platform's sales motion.
As of September 2026, the product is marketed as Prompt Security from SentinelOne, claims coverage of 15,000+ AI tools, ships a dedicated AI endpoint agent for local LLMs and MCP servers (February 2026), and offers no self-serve trial.

Questions worth asking before you renew

Will the employee-facing module stay available standalone, or will you be offered a Singularity platform bundle at renewal, and what does that do to your contract terms?
What happens to support SLAs, your account team, and response times while the integration is underway?
Now that the product sits inside an EDR platform company, how independent is the workforce AI roadmap, and how is it prioritised against endpoint security?

Where Aona stands

Aona is independent and purpose-built for Workforce AI Security, with seven Aona-managed hosting regions (AU, FR, UK, DE, US, SG, HK) and a 30-day guided trial, so you can evaluate the workforce surface on your own terms while those questions get answered.

Decision matrix

When to pick Aona

Five buyer scenarios, answered for employee AI use.

You need an LLM firewall and agent runtime guardrails for AI features in your own product.

Prompt Security (SentinelOne)

Prompt Security ships an application-side LLM firewall and agent runtime controls; Aona does not cover the AI-in-your-product surface. Verify the commercial path first, since the product has been sold through SentinelOne's Singularity platform since the 2025 acquisition, and note that the employee layer still needs its own control, which Aona ships with a 30-day guided trial.

Your problem is employees using ChatGPT, Claude, Gemini and Copilot, and you want a tool built for it.

Aona

Aona is purpose-built for employee AI use: the trial, the policy templates, the hard-block DLP and the layout-preserving file redaction all target that surface, with native ChatGPT, Copilot and Claude desktop app coverage. Prompt Security's employee module sits inside a platform whose centre is the application side.

You want to evaluate without a demo-led sales cycle or a platform contract.

Aona

Aona offers a 30-day guided free trial: IT deploys it with its existing tooling and the first signal arrives during the agreed evaluation. Prompt Security is demo-led with no self-serve trial and, since the 2025 acquisition, sold through SentinelOne's Singularity platform (as of September 2026).

You have AppSec exposure on AI features in your product AND a Shadow AI workforce problem.

Aona

Keep Prompt Security's LLM firewall for the application side and add Aona for the employee side, where it hard-blocks prompts and uploads on the device, coaches in real time and returns a first signal during the agreed evaluation. Two surfaces, two controls, no shared component.

You need documented data residency and a trial you can run yourself before the security review.

Aona

Aona ships seven Aona-managed hosting regions (AU, FR, UK, DE, US, SG, HK), with prompt processing selected separately, and a 30-day guided trial that IT deploys with its existing tooling. Prompt Security, sold through SentinelOne since the 2025 acquisition, has no self-serve trial, and its regional residency options are not publicly documented; confirm residency during procurement. As of September 2026.

Deployment

From evaluation to rollout.

Aona

Shape: Browser plugin for Chrome, Edge, Firefox and Safari plus a native endpoint app for Windows and macOS, deployed by IT with its existing software deployment tools (Intune is one option). No network routing or DNS changes.
Time to first signal: Agree during scoping
What IT must change: Push the plugin and the endpoint app with your usual deployment tooling and connect Microsoft Entra for admin SSO and user or group sync. Nothing changes on the network, in the SSE or in Microsoft 365.
Prerequisites: A software deployment tool for managed devices (Intune, Jamf or equivalent)
Microsoft Entra for admin SSO and user or group sync; general OIDC or SAML also works

Prompt Security (SentinelOne)

Shape: Browser extension for the employee module, a dedicated AI endpoint agent for local LLMs and MCP servers (February 2026), and an inline LLM proxy or SDK integration for the application side, sold through SentinelOne's Singularity platform.
Time to first signal: Weeks
What IT must change: Browser extension and endpoint agent push for the employee surfaces. The application side requires SDK or proxy integration with the product, and the purchase runs through Singularity.
Prerequisites: Identity provider for SSO
Engineering capacity to wire the LLM firewall into your application stack

Scope, stated plainly

Know the scope. Plan with confidence.

Aona

Aona secures employees' use of AI tools. It is not an LLM firewall, an AI-SPM tool or a red-teaming product for AI you build.
AI agent and MCP inspection ships in limited rollout on the native endpoint app, not general availability.
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.
Aona has a SOC 2 Type II examination report. No FedRAMP, IRAP or ISO 27001 today.

Prompt Security (SentinelOne)

Sold through SentinelOne's Singularity platform since the 2025 acquisition: contracts and renewals run through the platform sales motion, so the employee module is bought on platform terms (as of September 2026).
No self-serve trial: the site routes to a demo request (as of September 2026).
Data residency and processing regions are not publicly documented; confirm them in procurement before the security review.
Layout-preserving file redaction is not documented; the employee module describes prompt anonymisation and blocking.
Employee coaching is claimed on the employees page, but a learning loop with per-team trends is not documented; the platform's centre of gravity is the application side.

Make the move to Aona.

Aona replaces Prompt Security's employee module for the workforce side: hard-block DLP on prompts and uploads, layout-preserving file redaction, native desktop app coverage and real-time coaching, deployed with your existing device tooling and returning a first signal during the agreed evaluation. If you also have AppSec AI exposure, keep Prompt Security for the LLM firewall and agent runtime and run Aona alongside it for employees; the two surfaces do not share a component, and the Aona side can be proven on a 30-day guided trial before any contract changes.

What you keep

Existing identity provider (Entra / Okta / Google Workspace)
Existing device management tooling (Intune, Jamf or equivalent)
Prompt Security's LLM firewall and agent runtime, if those surfaces matter to you

What Aona replaces

Prompt Security's employee usage module for the workforce surface
Demo-led evaluation on platform terms for the workforce surface
Block-and-label-only file handling

What you turn off

Duplicate browser-DLP extensions on the same browser
Workforce-only contracts that bundle AppSec features you do not use

FAQ

Common questions from Prompt Security (SentinelOne) customers

Is Aona an alternative to Prompt Security or a complement?

For employee AI use, Aona is the alternative: hard-block DLP on prompts and uploads with no user override, layout-preserving file redaction, native ChatGPT, Copilot and Claude desktop app coverage, real-time coaching and a 30-day guided trial, against an employee module that is demo-led and sold through SentinelOne's Singularity platform. For the application side, LLM firewalls and agent runtime guardrails for AI you build, Prompt Security covers a surface Aona does not, so organisations with both exposures run Aona for employees and Prompt Security for the LLM firewall.

If we already use Prompt Security, why would we add Aona?

Add Aona for the employee layer. It brings layout-preserving DOCX, XLSX and PDF redaction on upload, native desktop app coverage for ChatGPT, Copilot and Claude, a hard block with no user override, policy templates for the EU AI Act, ISO 42001, SOC 2, ISO 27001, HIPAA and GDPR, per-team violation trends and Microsoft Sentinel export via OCSF, none of which Prompt Security's employee module documents. It also gives you a guided evaluation path that does not require renegotiating your Singularity contract: the 30-day trial runs on your devices and returns a first signal during the agreed evaluation.

Does Aona ship LLM firewalls or agent runtime guardrails like Prompt Security?

Aona ships AI agent inspection on the workforce side, in limited rollout today: the native endpoint app inspects running processes, network calls to AI providers, and loaded MCP server definitions on the employee machine. What Aona does NOT cover is application-side LLM firewalls or agent runtime guardrails for AI features built into your own product. That AppSec AI surface is Prompt Security's core, and Aona explicitly stays out of it.

How does Aona's trial compare to Prompt Security's evaluation path?

Aona offers a 30-day guided free trial: IT deploys the browser plugin and the endpoint app with its existing tooling, Microsoft Entra handles admin SSO, and the first signal arrives during the agreed evaluation. Prompt Security has no self-serve trial; evaluation starts with a demo request, and since the 2025 acquisition the product is sold through SentinelOne's Singularity platform. As of September 2026.

What does the SentinelOne acquisition mean for Prompt Security buyers?

SentinelOne announced its acquisition of Prompt Security on 5 August 2025 and completed it on 5 September 2025, at a price reported between USD 180 and 250 million. The product is now sold through SentinelOne's Singularity platform. Nothing public suggests it is going away; the honest diligence questions are whether you will be offered the standalone product or a Singularity bundle, how support continuity holds, and how independent the workforce AI roadmap stays inside an EDR platform company. If you chose Prompt Security partly for vendor independence, Aona remains an independent, purpose-built Workforce AI Security alternative with a 30-day guided trial. Facts verified July 2026.

Where does Prompt Security cover ground Aona does not?

On the application side: LLM firewalls and agent runtime guardrails for the AI you build into your own product, plus a dedicated AI endpoint agent for local LLMs and MCP servers. That is about securing your own AI, not about governing how employees use third-party AI tools. Many buyers run both, Prompt Security for the application layer and Aona for the employee layer. Choose Aona when the requirement is controlling employee AI use, with hard-block prompt and file DLP, layout-preserving redaction, real-time coaching and a 30-day guided trial.
