APIsec Alternative
APIsec is a continuous automated API security testing platform. Operator by Planck Proof does one thing and proves it: agentic API penetration testing where every finding ships with a reproducible proof you replay yourself, the pricing model is public, and your First Scan is free.
Continuous automated coverage, or a pentest that proves it
APIsec's pitch is continuous automated testing at scale across your API estate. Operator's pitch is depth on one job: agentic API penetration testing with a proof for every finding you can reproduce yourself.
| Operator by Planck Proof | APIsec | |
|---|---|---|
| Category | Agentic API pentester that chains and proves exploits | Continuous automated API security testing platform |
| Proof model | A portable, reproducible PoC you re-run yourself | Findings and evidence reported in the platform |
| Depth on API authz | BOLA, BFLA, business logic, per-finding proof | OWASP API Top 10 coverage at scale |
| Pricing | Pricing model published (per API, by endpoint volume); free First Scan; final price quoted | Enterprise, sales-led; pricing on request |
| Self-serve on-ramp | Free First Scan (one full proven scan) | Book a demo |
| Cadence | First Scan, Annual Assessment, or recurring (Pro) | Continuous |
APIsec is an established platform with broad continuous-testing capability and enterprise packaging. The contrast here is depth and reproducible proof, not a claim that APIsec lacks coverage. Please verify current APIsec capabilities and pricing directly with APIsec.
Continuous automation across the estate
APIsec is built to discover APIs and test them continuously against the OWASP API Top 10 at scale, which suits organizations that want automated, always-on coverage integrated into an enterprise program. That continuous breadth is a real strength for teams standardizing API security across many services.
We take a sharper bet. If the job is to prove what an attacker can actually do to your API, a focused agent that hands you a reproducible exploit beats a stream of alerts. Continuous coverage and reproducible proof are different emphases, and API exploitation rewards proof.
- API discovery. Finds and inventories APIs across the estate.
- Continuous testing. Always-on automated coverage.
- OWASP API Top 10. Broad automated checks at scale.
- Enterprise program fit. Built for large, standardized rollouts.
A proof you can carry out of the platform
Evidence that lives inside a vendor's platform proves exploitability to the vendor. A proof-of-concept you can replay on your own machine proves it to you. When the question is whether an attacker can really exploit your API, that difference is the whole answer.
- Portable, reproducible proof. Every finding ships with the request, response, reproduction steps, and a CVSS v3.1 vector your team replays independently.
- Real exploitation, not just detection. Operator chains BOLA, BFLA, broken auth, and injection into proven exploits rather than flagging classes of issues.
- Depth on API authorization. Focused on the flaws that top the OWASP API list and that fixed scans structurally miss.
- Public pricing model and a free First Scan. Run a full proven pentest for free, self-serve, before any demo or quote.
- Steerable, human-on-the-loop. Autonomous breadth by default, with a human able to direct the agent at the logic that matters to your product.
- 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 APIsec?
APIsec is a continuous automated API security testing platform that discovers APIs and tests them against the OWASP API Top 10 at scale. Operator by Planck Proof is a focused agentic API penetration testing agent whose defining standard is a reproducible proof-of-concept for every finding that you can replay yourself, backed by a free First Scan and public per-endpoint pricing.
Does APIsec give a proof you can replay yourself?
APIsec reports findings and evidence inside its platform. Operator's standard is a portable proof: every finding ships with the exact request, the response, and reproduction steps you re-run independently to confirm it, along with a CVSS v3.1 vector, rather than evidence you can only view in a dashboard.
How does pricing compare?
APIsec is enterprise and sales-led, with pricing shared on request. Operator publishes its model: pricing model published (per API, by endpoint volume); free First Scan; final price quoted. A team can run a full proven scan and see real exposure before any sales conversation.
Is Operator continuous like APIsec?
Yes. Operator's Pro tier runs recurring scans wired into your integrations, so regressions are caught as the API changes. The difference is depth and proof: Operator chains and proves real exploits like BOLA and BFLA and hands you a reproducible proof-of-concept for each, not only a continuous stream of alerts.
How do I get started with Operator?
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, with no demo or quote. Paid tiers add recurring testing and scale by endpoint volume, with the final price quoted.
Other alternatives, compared
Every comparison on this site is judged on one thing first: whether each finding ships a runnable proof-of-concept you can re-run yourself. See how Operator tests for BOLA and BFLA.
