WHY TEAMS LOOK FOR A PROMPT SECURITY ALTERNATIVE

Prompt Security is now a SentinelOne module. Not every team wants one.

Prompt Security earns strong reviews for AI usage control. Since SentinelOne acquired it in 2025, teams outside the SentinelOne ecosystem tend to weigh the same three questions: platform tie-in, scope and where their prompts get checked.

1. PLATFORM TIE-IN

Built into Singularity.

  • Acquired by SentinelOne in 2025.
  • Managed from the Singularity console.
  • No published vendor-direct pricing.
Great if you run SentinelOne. A detour if you don't.
2. SCOPE

A broad platform, with more to run.

  • Usage control, agent security and AI app security.
  • A browser extension plus a separate endpoint agent.
  • API, gateway or reverse proxy for apps and MCP.
Most teams just need to stop data leaking into AI.
3. PRIVACY BY DESIGN

Check the prompt where it's written.

Wald's small language model runs locally on each laptop, so sensitive prompts are classified on the device and never sent to another cloud to be inspected.

Protecting your data shouldn't mean shipping it somewhere else.

Focused AI DLP, independent of your endpoint vendor.

COVERAGE

Every AI surface. One lightweight rollout.

Wald covers ChatGPT, Claude, Gemini and Copilot in the browser, desktop AI apps, AI agents and MCP connections, all governed by one set of Allow, Warn and Block policies. It runs alongside whichever endpoint security you already use.

FOCUSED ON YOUR WORKFORCE'S AI USE. INDEPENDENT OF YOUR SECURITY STACK.

Prompt Security alternative FAQs

Talk to Sales

What is the best Prompt Security alternative?

Wald is a strong Prompt Security alternative for teams that want focused AI data protection without adopting the SentinelOne Singularity platform.

It provides context-aware AI DLP across browser AI tools, desktop AI apps, AI agents and MCP connections, checks every prompt on the device, and rolls out through the MDM you already use.

Is Prompt Security part of SentinelOne?

Yes. SentinelOne announced its acquisition of Prompt Security in August 2025 and has built it into the Singularity platform, where it is managed from the same console as SentinelOne's endpoint, cloud and identity products.

Wald is independent and runs alongside whichever endpoint security you already use.

How much does Prompt Security cost?

SentinelOne does not publish a vendor-direct price for Prompt Security. Pricing is quote-based through SentinelOne and its resellers.

Wald offers per-user quotes directly, with no platform bundle required. Book a demo to get pricing for your team.

Does Wald cover desktop AI apps, agents and MCP like Prompt Security does?

Yes. Wald covers ChatGPT, Claude, Gemini, Grok and Microsoft Copilot in the browser, desktop AI apps such as the ChatGPT desktop app, and AI agents and MCP connections, all under one policy approach.

Where does Wald inspect AI prompts?

On the endpoint. Wald's small language model runs locally, so prompts and file uploads are evaluated before they leave the device and are never sent to another cloud to be checked.

What policy actions does Wald support?

Allow, Warn and Block, set by AI tool and by the sensitivity of the data being shared. Wald coaches employees inline when it warns or blocks, so legitimate AI work keeps moving.

How hard is it to switch from Prompt Security to Wald?

Wald is rolled out through your existing MDM or endpoint management on Windows and macOS, with no proxy or traffic rerouting.

You can start by monitoring AI usage, then turn on Warn and Block policies for the riskiest tools and data. We'll map out a migration plan with you during your demo.

Does Wald help with HIPAA, GDPR and CCPA compliance?

Yes. Wald helps organizations maintain compliance with HIPAA, GDPR, CCPA and other data protection laws, with an audit-ready record of AI interactions and a SOC 2 compliant platform.
