Nightfall covers SaaS DLP broadly.
Aona governs AI on the endpoint.
Nightfall has a deep ML detector library and broad SaaS API coverage (Slack, M365, Drive, Salesforce). Aona is purpose-built for Workforce AI Security with native desktop AI app coverage, framework-aligned templates, and AU residency by default. They cover different surfaces and most regulated organisations need both.
AI-native DLP platform with mature SaaS API connectors, a browser plugin, and lightweight endpoint agents.
Workforce AI Security platform purpose-built for the regulated mid-market, with browser plugin, native endpoint app, and a 90-day self-serve trial.
Keep Nightfall for SaaS DLP across Slack, M365, Drive, and Salesforce. Add Aona for AI prompt DLP at the browser and native endpoint layer, framework templates out of the box, and AU data residency. Complementary surfaces, not the same tool.

When to pick which
Five scenarios. The honest answer for each one.
Your top requirement is SaaS DLP across Slack, M365, Drive, and Salesforce.
Nightfall has API connectors across most major SaaS surfaces. Aona does not cover SaaS APIs today.
Your IdP is Okta and you need SCIM auto-provisioning today.
Nightfall ships an Okta integration. Aona is Microsoft Entra only and has no SCIM provisioning.
You need AI prompt DLP at the browser and native endpoint layer.
Aona ships browser plugin plus native desktop AI app interception (ChatGPT, Copilot, Claude desktop). Nightfall focuses on SaaS-side and a smaller endpoint surface.
You are an AU-regulated buyer who needs in-country data residency.
Aona is AU-only by design. Nightfall does not publicly document an AU region.
You have a Slack / M365 DLP problem AND an AI prompt DLP problem.
Different surfaces, no conflict. Nightfall handles SaaS DLP; Aona handles the AI prompt and file surface on the endpoint.
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 | Nightfall AI |
|---|---|---|---|
| Discover | |||
| Shadow AI inventory across endpoints | Browser surface | Browser plus native AI apps | Endpoint signal, less granular |
| SaaS API connectors (Slack, M365, Drive, Salesforce) | Core surface | ||
| Native desktop AI app interception (ChatGPT, Copilot, Claude desktop) | Plus generic process-signature detection | Endpoint agent, scope unclear | |
| Govern | |||
| Out-of-the-box framework templates (EU AI Act, ISO 42001, sector) | |||
| Hard-block on prompt with no soft override | Block, sanitization, coaching options | ||
| Mature ML detector library (100+) | Smaller catalog today | Same catalog as browser | Multi-year detector refinement |
| Protect | |||
| Browser plugin (Chrome / Edge / Firefox) | Plus native scope | ||
| File redaction with layout preservation (DOCX / Excel) | Length-matched entity replacement | Length-matched entity replacement | Entity sub, layout fidelity unclear |
| Operations | |||
| Identity / SSO | Microsoft Entra only | Microsoft Entra only | Okta, Entra, Google Workspace |
| SCIM auto-provisioning | |||
| Data residency | AU only today | AU only today | US default; AU not documented |

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 (Okta or Entra)
- Browser MDM coverage
Where each one falls short
From public docs and customer interviews. If you find a factual error, email trust@aona.ai.
- Smaller ML detector library than Nightfall. Multi-year detector refinement is genuinely on their side.
- No SaaS API connectors today (Slack, M365, Drive, Salesforce). Nightfall ships these as standard.
- Microsoft Entra only for SSO. No Okta-native, no SCIM auto-provisioning.
- Pre-revenue with two pilots. Nightfall has hundreds of paying customers and a 4.4-star Gartner Peer Insights presence.
- AU data residency is not publicly documented. Default deployment is US AWS.
- Native desktop AI app interception (ChatGPT, Copilot, Claude desktop) is not explicitly documented.
- Layout-preserving DOCX / Excel redaction with length-matched entity replacement is not the same depth Aona ships.
- Sales-led only. Enterprise ACVs typically start in the high five figures with no public per-seat list.
How Aona and Nightfall AI work together
Run them at different surfaces. Nightfall handles SaaS DLP across the apps your organisation already uses (Slack, M365, Drive, Salesforce, etc.). Aona handles AI prompt and file DLP at the browser and native endpoint, where employees use ChatGPT, Copilot, Claude, and other AI tools. Together you get DLP coverage from collaboration tools to AI tools without overlap.
SaaS layer
Nightfall's API connectors scan content moving through Slack, M365, Drive, and other SaaS apps.
AI prompt layer
Aona intercepts at the browser plus native AI apps. Hard-block DLP on prompts and file uploads.
End-to-end DLP coverage
SaaS data is governed by Nightfall; AI prompts and files are governed by Aona.
