Comparison
CitrusGlaze vs Prompt Security
Prompt Security built a cloud proxy for AI traffic, then sold to SentinelOne for ~$200M. Same price as CitrusGlaze ($10/user/mo) — but your traffic now routes through a public company's cloud. Why pay the same and send data to a third party?
| Feature | CitrusGlaze | Prompt Security |
|---|---|---|
| Status | Gourmand Labs LLC | Acquired by SentinelOne (~$200M, Sep 2025) |
| Approach | Local MITM proxy (AI Traffic Control) | Cloud proxy (traffic routes through SentinelOne) |
| Data processing | 100% local — nothing leaves your machine | Cloud-processed (SentinelOne's infrastructure) |
| Price | Free tier + $10/user/month | $10/user/mo employees, $25/mo dev seats |
| AI tool coverage | 39+ verified (CLI, SDK, agents, browser) | GenAI apps (broader employee coverage) |
| Policy engine | Cedar (declarative, auditable, open standard) | Proprietary rules engine |
| MCP support | MCP Gateway (built-in proxy) | Limited MCP coverage |
| Open source components | Scanner is open source (MIT) | Prompt Fuzzer (open source) |
| Independence | Gourmand Labs LLC | SentinelOne subsidiary (~$7B market cap) |
Different tools for different problems
Choose CitrusGlaze if you need
- ✓ 100% local processing — same proxy approach, but data stays on your machine
- ✓ Vendor independence — no acquisition risk for your security stack
- ✓ Same price ($10/user/mo) without sending data to a third party
- ✓ Cedar policy engine — declarative, auditable, open standard policies
- ✓ No network routing changes — local proxy, not cloud proxy
- ✓ Open source scanner — verify detection patterns yourself
Choose Prompt Security if you need
- ✓ Backing of SentinelOne (public company, ~$7B market cap)
- ✓ Similar proxy architecture — they understand the approach
- ✓ Broader GenAI app coverage (not just developer tools)
- ✓ Enterprise support team via SentinelOne
- ✓ Prompt Fuzzer open-source tool for red-teaming
Key differences
Same approach, different trust model
Prompt Security is the most architecturally similar competitor to CitrusGlaze — both use a proxy to intercept AI traffic. The critical difference: Prompt Security routes your traffic through SentinelOne's cloud. CitrusGlaze runs the proxy locally on each machine. Same concept, fundamentally different data handling. Your prompts, code, and secrets stay on your device with CitrusGlaze. With Prompt Security, they traverse SentinelOne's infrastructure.
The acquisition question
Prompt Security is now part of SentinelOne's Singularity platform (acquired September 2025 for ~$180-250M). Both products use a proxy architecture. The key difference: Prompt Security routes traffic through SentinelOne's cloud for analysis. CitrusGlaze processes everything locally on your machine. Same approach, different trust model.
Same price, different value proposition
Prompt Security charges $10/user/month for employees and $25/month for developer seats. CitrusGlaze is $10/user/month. Nearly identical pricing — but with CitrusGlaze, your data never leaves your machine. Why pay the same price and send your prompts, secrets, and code through a third party's cloud when you can keep everything local?
Cedar vs proprietary policies
CitrusGlaze uses Cedar, an open policy language created by AWS. Policies are declarative, version-controlled, and auditable. You can read every rule. Prompt Security uses a proprietary rules engine — you trust their system to make the right decisions. For teams that need to prove compliance or audit their security policies, Cedar's transparency matters. For prompt-level DLP, knowing exactly what's blocked and why is not optional.
Honest assessment
Prompt Security built a legitimate product. Their proxy-based approach validates the architecture — if you want to secure AI traffic, intercepting it at the network layer is the right idea. Their Prompt Fuzzer open-source tool built credibility in the security community. The SentinelOne acquisition (~$200M) proves the market values this approach. They understood the problem before most.
But that acquisition changes the equation. Your AI traffic — every prompt, every code snippet, every API key that almost leaked — now routes through a public company's cloud infrastructure. SentinelOne is a $7B endpoint security company with their own priorities, their own data handling practices, and their own roadmap. Prompt Security's product will evolve to serve SentinelOne's strategy, not necessarily yours.
CitrusGlaze is a smaller, earlier-stage team building the same concept with a different trust model: everything stays local. We're transparent about our stage. Our advantage is that your data never leaves your machine, our policies are auditable Cedar rules you can read, and there's no corporate parent to change the terms. If you believe AI traffic should be secured locally, that's what we built.
