Start with the action you need to protect.
A prompt. A file. The controls your people rely on.
How to compare the options
Start with Aona's supported hard-block, file-redaction and employee-guidance controls. Your existing stack may already protect some AI actions. Compare the same app, account, client and input path, then use a guided evaluation to check the additional protection you need. Hosting and prompt-processing choices are separate from the AI provider's handling.
Scope and sources
A closer look at your stack.
Open a product to review its scope, supporting sources and the Aona comparison.
Harmonic SecurityAI-native data securityScope and sources
The product
Browser extension plus desktop client with real-time prompt redaction and an MCP gateway; SOC 2, ISO 27001 and ISO 42001 certifications.
Harmonic Security platformWhat to consider
No self-serve trial: the site routes to a demo request (as of September 2026), and no layout-preserving file redaction claimed.
Where Aona fits
Evaluate supported hard blocks and layout-preserving DOCX, XLSX and PDF redaction, with the employee response and hosting configuration in scope.
Read the comparison ↗Check Point Workforce AI SecuritySecurity suite moduleScope and sources
The product
Employee AI controls sold through the Infinity Portal, with an Essentials edition (browser extensions only) and an Enterprise edition (extensions plus desktop agent for web, desktop, MCP and IDEs), and an agentless path on the AI Network Firewall.
Check Point Workforce AI Security admin guideWhat to consider
Desktop, MCP and IDE coverage need the Enterprise edition; no self-serve trial (as of September 2026); residency for the workforce module not documented.
Where Aona fits
Review the Windows/macOS client and supported desktop action, protected document output and Aona-managed or customer-hosted configuration.
Read the comparison ↗Lasso SecurityAI Usage ControlScope and sources
The product
Employee AI discovery, data masking, role-based policies, coaching and audit trails inside a broader AI security platform that also covers applications and agents.
Lasso AI Usage ControlWhat to consider
Demo and assessment led, with no self-serve trial (as of September 2026); layout-preserving file redaction and a published residency choice are not documented.
Where Aona fits
Test a supported block without user override or a redacted document that remains useful, then review employee guidance and the required deployment.
Read the comparison ↗WitnessAINetwork AI securityScope and sources
The product
Network-level protection, routing, policies and reporting for human and agentic AI use, with single-tenant isolation and multi-region deployment; listed on AWS Marketplace and sold through a demo request.
WitnessAI platformWhat to consider
Inspects traffic routed through its platform: certificate-pinned apps, unrouted paths and devices off the inspected network sit outside it, and there is no self-serve trial.
Where Aona fits
Evaluate a supported employee action through the deployed browser plugin or native app. Agree the inspection path, policy response and observation period.
Read the comparison ↗LayerX (Akamai Workforce Protector)Browser securityScope and sources
The product
Browser-extension security across Chrome, Edge, Firefox and Safari with AI usage controls that warn, redact, block or guide; sold by Akamai since July 2026.
Akamai Workforce ProtectorWhat to consider
Desktop coverage is claimed but the enforcement component for desktop apps is not documented; no AI policy templates; no self-serve trial (as of September 2026).
Where Aona fits
Review the Windows/macOS native client, policy templates and required input action. Validate the client release and data-handling configuration.
Read the comparison ↗Nightfall AIAI-era DLPScope and sources
The product
API connectors for Slack, M365, Drive and Salesforce plus browser and endpoint agents, with an MCP gateway in early access; SOC 2 Type 2; databases hosted in the United States.
Nightfall AI platformWhat to consider
Proof of value instead of a self-serve trial (as of September 2026), US-only hosting, and no layout-preserving redaction of uploaded documents claimed.
Where Aona fits
Evaluate layout-preserving DOCX, XLSX and PDF redaction on the supported upload path, alongside blocking and the available employee guidance.
Read the comparison ↗Microsoft PurviewMicrosoft 365 data securityScope and sources
The product
Blocks sensitive prompts and uploads to consumer AI sites through Edge for Business, the Purview extension for Chrome and one-click DLP for Firefox, on onboarded Windows devices, with a network data security path for local AI apps via Global Secure Access or a SASE partner.
Microsoft Learn: Purview for other AI appsWhat to consider
Scope and licensing depend on the policy location, app, account, device and browser. Enterprise-connector audit support does not establish DLP; check the specific control.
Where Aona fits
Scope Aona blocking and document redaction for the selected AI app and installed client. Test coexistence and confirm the licensing for your existing Microsoft control.
Read the comparison ↗Zscaler AI Access SecuritySSE / SASEScope and sources
The product
AI app discovery, allow, block or coach access policies, prompt visibility across 250+ GenAI apps and inline DLP for traffic steered through the Zero Trust Exchange; sold as a separate GenAI Security add-on.
Zscaler AI Access SecurityWhat to consider
Network content inspection depends on the configured traffic-steering and TLS-inspection path. Confirm supported clients, file actions and the current evaluation route.
Where Aona fits
Evaluate supported prompt and file controls through the deployed Aona client. Review local inspection prerequisites and coexistence with the configured Zscaler path.

Microsoft Purview DSPM for AI
Microsoft ecosystem
E5 and Copilot-centric estates.
Read the comparisonProduct details
Microsoft's data security posture layer for AI. Deepest inside the M365 and Copilot estate, and blocks sensitive prompts to consumer AI through Edge for Business and the Purview extension for Chrome.
