Prompt Security goes wider.
Aona goes deep on employee governance.
Prompt Security covers many AI security surfaces: LLM firewalls, agent runtime, application-side guardrails, plus employee usage controls. Aona is narrower on purpose: Workforce AI Security with hard-block DLP, file redaction, and a self-serve trial. The right pick depends on which surfaces matter to you.
Broad AI security platform covering LLM firewalls, agent runtime guardrails, employee usage controls, and developer-side AI hardening, now part of SentinelOne and sold through its Singularity platform.
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.
Pick Aona if your problem is Workforce AI Security: a focused tool with a 30-day self-serve trial, published pricing, hard-block DLP for prompts and files with layout-preserving redaction, and 7-region data residency. Pick Prompt Security only if you also need application-side AI security (LLM firewalls, agent runtime guardrails, developer-side controls) and are comfortable buying through SentinelOne's Singularity platform, which has sold the product since the 2025 acquisition. Run both if you need wide AI security plus deep employee governance.

Vendor facts last verified July 2026
What the SentinelOne acquisition changes
- 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 July 2026, the product keeps the Prompt Security name, claims coverage of 15,000+ AI tools, publishes no pricing or self-serve trial, and holds a 4.7 rating on Gartner Peer Insights from 3 reviews.
- ?Will the employee-facing module stay available standalone, or will you be quoted a Singularity platform bundle at renewal, and what does that do to price?
- ?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?
Aona is independent and purpose-built for Workforce AI Security, with 7-region data residency (AU, FR, UK, DE, US, SG, HK) and a 30-day self-serve trial, so you can evaluate the workforce surface on your own terms while those questions get answered.
When to pick which
Five scenarios. The honest answer for each one.
You need LLM firewalls and agent runtime guardrails for AI features in your own product.
Prompt Security ships an application-side LLM firewall and agent runtime controls. Aona does not cover the AI-in-your-product surface today.
You want one platform that covers AppSec / dev-side AI plus employee AI usage in a single contract.
Prompt Security's breadth means one vendor across both surfaces. Aona is workforce-only by design; pairing it with a separate AppSec AI tool is a two-vendor stack.
Your problem is workforce AI usage (ChatGPT, Claude, Gemini, Copilot) and you want a focused tool, not a broad platform.
Aona is purpose-built for Workforce AI Security. The roadmap, the trial, the policy templates, and the file redaction engine are all aimed at that use case.
You want to evaluate without a paid POC or multi-week sales-led setup.
Aona offers a 30-day self-serve free trial. Prompt Security typically runs a sales-led evaluation across multiple surfaces, which lengthens the cycle.
You have AppSec exposure on AI features in your product AND a Shadow AI workforce problem.
These are different surfaces. Prompt Security covers the application side; Aona covers the workforce side. Most regulated organisations need both kinds of controls.
You need in-region data residency and published pricing before security review.
Aona publishes per-seat pricing and ships 7 data residency regions (AU, FR, UK, DE, US, SG, HK). Prompt Security, sold through SentinelOne since the 2025 acquisition, does not publish pricing, and regional residency options are not publicly documented; confirm both during procurement. As of July 2026.
What each tool actually does
Three columns on the Aona side because the browser plugin and the native endpoint app cover different surfaces. Browser-only customers will see fewer green checks than customers with both.
| Capability | Aona browser plugin | Aona native app | Prompt Security |
|---|---|---|---|
| Discover | |||
| Workforce shadow AI tool discovery (managed devices) | Browser surface | Browser plus native AI apps | Vendor claims 15,000+ AI tools |
| Native desktop AI app interception (ChatGPT, Copilot, Claude desktop) | |||
| Application-side LLM traffic visibility | LLM firewall, core capability | ||
| Agent runtime visibility (in your own product) | Out of scope | ||
| Govern | |||
| Hard-block DLP on AI prompts (workforce side) | Modal pauses, no override | ||
| Application-side LLM firewall | Core capability | ||
| Real-time employee coaching | |||
| Out-of-the-box framework templates (EU AI Act, ISO 42001, sector) | |||
| Protect | |||
| File redaction with layout preservation (DOCX / Excel) | Length-matched replacement | Length-matched replacement | Detection-oriented |
| Inline prompt redaction before send | |||
| Operations | |||
| Time to first signal | Hours | Hours | Days to weeks |

Based on vendor documentation as of July 2026. Email trust@aona.ai if you find a factual error.
What it takes to ship each one
- Microsoft Intune (Windows MDM, only path shipped)
- Microsoft Entra (admin SSO + user/group sync)
- Identity provider for SSO
- Engineering capacity to wire the LLM firewall into your application stack
Where each one falls short
From public docs and customer interviews. If you find a factual error, email trust@aona.ai.
- Narrower scope than Prompt Security: no LLM firewall, no agent runtime controls, no AppSec AI hardening today.
- Microsoft Entra is the production SSO path, plus general OIDC / SAML. No native Okta connector or SCIM provisioning, and SOC 2 Type II is the only certification today: no FedRAMP or IRAP.
- Workforce-side AI agent and MCP inspection is in limited rollout today, not generally available. Prompt Security enforces agent runtime policy on the application side, which Aona does not cover.
- Breadth comes with complexity: longer sales cycle, no self-serve trial, more surfaces to configure.
- Workforce-side employee coaching is part of a broader product, not the focus. Depth on file redaction and behaviour-change reporting is not on par with a workforce-specialist tool.
- Pricing is typically anchored at the enterprise tier, which can over-spec mid-market organisations whose problem is workforce AI only.

Migrating from Prompt Security
If your only problem is workforce AI usage, switching from Prompt Security to Aona simplifies the stack and the spend. If you have AppSec AI exposure too, the right move is to keep Prompt Security for the LLM firewall and agent runtime, and either run Aona alongside it for workforce or stay on Prompt Security's workforce module if breadth is the priority.
- Existing identity provider (Entra / Okta / Google Workspace)
- Existing MDM (Intune)
- Prompt Security's LLM firewall and agent runtime, if those surfaces matter to you
- Prompt Security's workforce / employee usage module (for orgs that only need workforce coverage)
- Sales-led evaluation cycle for the workforce surface
- Block-and-label-only file handling
- Duplicate browser-DLP extensions on the same browser
- Workforce-only contracts that bundle AppSec features you do not use
