Aona vs the field: an honest decision matrix
Aona against five categories: SSE / network, Microsoft 365 / Purview, cloud DLP, model GRC, and AI-native pure plays. Categories are described as categories, not any single vendor.

When Aona is the right choice, and what it is not for
Start here. The left column is the buyer Aona is built for. The right column lists the problems Aona does not solve, and what to check before you decide.
Aona is the right choice when
- ✓Your problem is how employees use third-party AI tools such as ChatGPT, Claude, Gemini, and Copilot, in the browser and in native desktop apps.
- ✓You need supported hard-block, layout-preserving DOCX, XLSX and PDF redaction, and employee guidance for a defined prompt or upload path.
- ✓You need to review seven Aona-managed hosting options, the SOC 2 Type 2 report and rollout through your existing IT tooling, with the configuration agreed before deployment.
- ✓You want a guided 30-day trial with a defined population, synthetic test inputs and a reviewable policy outcome.
Aona is not for you when
- ✕Your only requirement is governance for models you build: inventories, bias audits, EU AI Act conformity documentation. That is model governance (Credo, Holistic, OneTrust). Teams that build AI still add Aona for the employees who use it.
- ✕Your only requirement is an LLM firewall or red teaming for AI features you ship to customers. Aona does not cover that surface; it covers the employees who use AI tools.
- ✕You cannot put any software on the devices in question, such as unmanaged contractor machines or phones. Aona needs its plugin or endpoint app on the device. A network-only path inspects steered traffic and cannot hard-block a prompt or redact a file on the device.
- ✕You are buying one suite contract for network, email, and identity and will not add a second vendor for AI. Confirm Aona's supported clients, inspection paths and coexistence requirements with your existing suite before you decide.
Aona vs the field, dimension by dimension
Six columns, eight evaluation dimensions. Aona wins the employee AI rows; suite breadth and model governance belong to their own categories, and we say so. Each column describes the category, not any single vendor.

|---|---|---|---|---|---|---|
| Employee AI usage visibilityEdge: Aona | ✓10,000+ AI tool catalog, browser plus desktop | ~Domain-level app visibility from network traffic | ~Microsoft 365 and selected third-party AI paths; scope depends on policy location and setup | ~Sees connected SaaS and endpoint data flows | ✕Model inventories, not employee usage | ~Core capability; browser-only or network-only depending on the vendor |

| Endpoint plus browser coverageEdge: Aona | ✓Browser plugin (Chrome, Edge, Firefox, Safari) plus native app for Windows and macOS | ~Network first; endpoint needs extra agents | ~Edge, Chrome with the extension, and M365 apps; native AI apps need the network path | ~Cyberhaven on endpoint; Nightfall is API-first | ✕No endpoint or browser presence | ~Mixed: browser-only or network-only per vendor |

Legend: ✓ strong fit · ~ partial or conditional · ✕ not what this category is for.
Aona capability status, stated plainly: AI agent inspection is in limited rollout. Layout-preserving redaction for DOCX, Excel, and PDF is available today.

One paragraph per category
The one-line framing for each stack, then the verdict for employee AI use, then the full side-by-side page if you want the detail.
SSE / network security
Zscaler, Netskope, Check PointYour SSE inspects steered traffic. Aona enforces on the device, at the prompt and the upload.
For employee AI use, start with Aona's supported hard-block, file-redaction and employee-guidance controls. SSE products also offer AI inspection and access policies; Zscaler documents allow, block and coach actions. Compare the exact product, licence, traffic path and TLS-inspection configuration. Evaluate document output and native-client support separately, and test coexistence before adding controls to an installed stack.
Microsoft 365 / Purview
Purview, Defender, EntraPurview has defined Microsoft 365 and third-party AI controls. Aona focuses on supported employee AI submissions.
For employee AI use, start with Aona's supported blocking, file-redaction and employee-guidance controls. Microsoft Purview also documents third-party AI and Copilot controls. Licensing and behaviour depend on the policy location, app, account, device and browser; connector audit support is not proof of DLP. Use a matched input and the current provider documentation to evaluate the additional control your workforce needs.
Cloud DLP
Nightfall, CyberhavenCloud DLP protects data at rest and in SaaS. Aona enforces at the moment an employee uses AI.
For employee AI use, pick Aona. Nightfall's API connectors scan Slack, M365, Drive, and Salesforce at rest, and Cyberhaven traces data lineage across endpoints; both now market AI controls, and neither documents layout-preserving file redaction, AI policy templates for the EU AI Act and ISO 42001, a published seven-region residency choice, or a self-serve trial. Aona starts from the employee AI problem: a 10,000+ tool catalog, prompt-level policy with a hard block, redaction that keeps the document usable, and employee guidance with policy events for review on the supported path. Keep the DLP suite for data at rest; add Aona for the prompt and the upload.
Model GRC
Credo AI, Holistic AI, OneTrustGRC documents policy for the AI you build. Aona enforces policy on the AI your employees use.
Model governance platforms win their own row: if you build or deploy your own models and need registries, bias audits, conformity assessments, and EU AI Act documentation, Credo AI, Holistic AI, and OneTrust are built for exactly that. None of them touches the employee at the moment a risky prompt is typed, none ships a browser plugin or an endpoint app, and none hard-blocks or redacts an upload. For employee AI use, pick Aona; regulated organisations that build AI run both, with policy documented in the GRC platform and enforced by Aona at the keyboard.
AI-native pure plays
Harmonic Security, WitnessAI, LassoThe closest comparison, and the one Aona wins on evaluation terms.
Harmonic, WitnessAI, Lasso, and Aona all discover employee AI use and enforce prompt-level policy, so the decision comes down to enforcement depth and how you can evaluate. WitnessAI inspects at the network with no endpoint agent; Harmonic is extension-first; all three are demo-led, with no self-serve trial (as of September 2026). Aona enforces on the device across the browser and the native desktop apps, blocks with no override, redacts DOCX, XLSX, and PDF in place, coaches in real time, publishes seven hosting regions, and offers a guided 30-day trial scoped to the app, installed client and policy response your team needs.
