An Equixly alternative that proves it, your way
Equixly is a serious agentic API pentester built on a proprietary reinforcement-learning engine, sold to regulated European enterprises. Operator by Planck Proof shares the agentic, API-native premise and goes one step further on the thing that matters most: every finding ships with evidence you can reproduce yourself, on your own target. Your first scan is free, so you see your real exposure before you ever talk to sales.

Same premise, a higher bar on proof
Both are agentic and API-native, and both chain multi-step API calls to find BOLA, BFLA, and business-logic flaws that scanners miss. The difference is what "proof" means, whether you can reproduce it independently, and how you buy.
| Operator by Planck Proof | Equixly | |
|---|---|---|
| Proof model | Reproduce it yourself: request/response, reproduction steps, CVSS v3.1 | "Exploit-validated": a logged request sequence inside the report |
| Verification | Your team replays the finding to confirm it | Read the evidence trail in the PDF |
| Benchmarking | Reproducible, run against your own target | Self-run studies on Equixly's own range |
| Engine | Steerable agentic, human-on-the-loop | Autonomous reinforcement-learning agent |
| API coverage | REST, GraphQL, gRPC, every operation | REST, GraphQL, gRPC |
| Getting started | Free first scan: a full proven pentest | Book a pentest or request a quote |
| Availability | US and beyond | EU-centric (strong on EU data residency) |
Equixly is a well-regarded, Series-A-funded vendor with marquee European enterprise customers and genuine business-logic depth. The contrast here is about reproducible proof, how you buy, and where you operate, not about whether Equixly does serious work. It does.
A credible, EU-native agentic pentester
Equixly built a proprietary reinforcement-learning engine rather than wrapping a general-purpose model, and it shows in their state-aware testing: capturing resource IDs and replaying them across create, read, update, and delete sequences to surface authorization and business-logic flaws. For a European enterprise that needs its data to stay in the EU, their residency posture is a real advantage.
We agree with Equixly's core bet: the way to test a modern API is with an agent that reasons across multi-step calls, not a scanner firing fixed payloads. Where we differ is on the standard of proof and on who gets to verify it.
- Proprietary RL engine. State-aware, multi-step API testing rather than an LLM wrapper.
- EU data residency. A genuine fit for European regulated buyers who need data to stay in-region.
- Transparent, productized pricing. A published flat-fee pentest, rare in this market.
- Enterprise trust. Marquee EU finance and energy logos and analyst recognition.
Proof you can reproduce, and a way to start today
An exploit noted inside a vendor's report asks you to trust the vendor. An exploit you can replay yourself asks you to trust nothing. That is the line Operator is built on, and it is where an agentic API pentest should compete.
- Reproduce every finding yourself. Each result ships with the exact request and response, reproduction steps, and a CVSS v3.1 vector, so your engineers can replay it and confirm it independently. Anything the agent cannot reproduce never reaches your report.
- Benchmarks you can re-run. Instead of a study run on our own range, point Operator at your own target and judge the result on your surface, with evidence you can check.
- Steerable, human-on-the-loop. Keep autonomous breadth by default, then direct the agent at the specific business logic and edge cases that matter to your product.
- Your first scan is free. It runs a full agentic penetration test and proves each finding, so you see the value before you pay, with no sales call. Paid tiers add continuous re-testing and scale by endpoint volume, so coverage grows with your attack surface rather than a fixed package.
- Available where you operate. A fit for US teams and buyers whose data, customers, or compliance frameworks sit outside the EU.
- Recognized method. Structured against OWASP API Top 10 and WSTG, ASVS, PTES, NIST SP 800-115, MITRE ATT&CK, and CVSS v3.1.
Common questions
How is Operator different from Equixly?
Equixly is an agentic API pentester built on a proprietary reinforcement-learning engine, sold as a cloud service to regulated European enterprises. Operator by Planck Proof shares the agentic, API-native premise but proves every finding with evidence you can reproduce yourself, from the exact request and response to replayable reproduction steps, and it offers a free self-serve first scan without a sales call.
What does "exploit-validated" mean at Equixly, and how is Operator's proof different?
Equixly documents an exploit as a logged request sequence inside its audit report. Operator is proof-first in a way you can verify without us: every finding ships with the request and response, reproduction steps, and a CVSS v3.1 vector, so your own team can replay it and confirm it. Anything the agent cannot reproduce does not reach your report.
Is Operator available outside Europe?
Yes. Equixly is EU-centric, which is a genuine advantage for European data-residency requirements. Operator serves teams in the US and beyond, so it is a fit when your buyers, data, or compliance frameworks sit outside the EU.
Can I try Operator without talking to sales?
Yes. Your first scan is free and self-serve: a full agentic run that tests every operation and proves each finding with a reproducible proof-of-concept before any demo or quote. Paid tiers add continuous re-testing and scale by endpoint volume, so coverage grows with your attack surface.
Do both tools test for BOLA and business-logic flaws?
Yes. Both are agentic and API-native and both chain multi-step API calls to find BOLA, BFLA, and business-logic abuse that scanners miss. The difference is not whether they look for these flaws, but how the resulting exploit is proven and whether you can reproduce it independently.
