Comparison
CitrusGlaze vs Prompt Security
Prompt Security built a cloud proxy for AI traffic, then sold to SentinelOne for ~$200M. Your traffic now routes through a public company's cloud. CitrusGlaze is free for developers and keeps everything local.
| Feature | CitrusGlaze | Prompt Security |
|---|---|---|
| Status | Gourmand Labs LLC | Acquired by SentinelOne (~$200M, Sep 2025) |
| Approach | Local prompt firewall (AI Traffic Control) | Cloud proxy (traffic routes through SentinelOne) |
| Data processing | Local-first — AI traffic inspected on your device | Cloud-processed (SentinelOne's infrastructure) |
| Price | Free + enterprise pricing | $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
- ✓ Local-first processing — same approach, but AI traffic is inspected on your device
- ✓ Vendor independence — no acquisition risk for your security stack
- ✓ Free for developers — 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 intercept AI traffic at the network layer. The critical difference: Prompt Security routes your traffic through SentinelOne's cloud. CitrusGlaze runs its AI inspection engine locally on each machine. Same concept, fundamentally different data handling. Your prompts, code, and secrets are inspected 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 free for developers, with enterprise pricing on request. With CitrusGlaze, AI traffic is inspected locally — your prompts, secrets, and code never pass through a third party's cloud.
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 AI traffic is inspected locally, 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.
