Data Theorem: cost, fit and limits
Data Theorem is an application and API security platform made by Data Theorem, Inc. that discovers APIs, tests them the way an attacker would and protects them at runtime, with AI features for exploit analysis and remediation, sold to security teams on request.
What to know first
Data Theorem publishes no prices, plan tiers or free plan: the pricing page offers a demo request and nothing else. The homepage names API Secure as the API product and lists AI Exploits, AI Auto-Remediation and AI Active Protection as AI features. Certifications, hosting region and named integrations did not appear on the pages we read, so a buyer should collect those in writing during the sales conversation.

Who Data Theorem is best for
Teams consolidating API testing and protection
The homepage describes discovery, attacker-style testing and runtime protection as one flow in API Secure, which suits a team that would rather not join separate scanners and gateways.
Security groups curious about AI-assisted triage
AI Exploits, which the vendor says reads every verified finding across apps and APIs, and AI Auto-Remediation are named features worth putting to a demo, since the pages explain little more.
Buyers who also secure code and mobile apps
The code security description names SAST, SCA and SBOM next to the API product, so teams wanting application and API coverage from one vendor have a reason to ask.
Data Theorem plans and pricing
| Plan | Price | What it includes |
|---|---|---|
| API Secure | Not published | The API product on the homepage: discover every API, test it like an attacker, protect it at runtime. Pricing page shows a demo request only. |
| AI Security | Not published | A demo option listing AI Active Protection among its items. No tier names, user counts or limits appear on the pages opened. |
| Free plan | None shown | The pricing page opened shows no free plan and no trial, only a form to request a demo. |

What Data Theorem does
- API Secure
- The homepage describes API Secure as discovering every API, testing it like an attacker and protecting it at runtime. The dedicated product page at /api-security returned a 404, so detail rests on the homepage.
- AI Exploits
- Data Theorem says its ARCANE engine reads every verified finding across your apps and APIs. The pages opened do not explain how the engine ranks or confirms exploits.
- AI Auto-Remediation
- The code security description names AI Auto-Remediation beside SAST, SCA and SBOM. The pages opened give no example of the fixes it produces or how they reach a repository.
- AI Active Protection
- Listed under the AI Security demo option on the pricing page. The vendor gives no further description there of what it blocks or where it sits in traffic.
- Closed-loop AI security platform
- A vendor press release uses this phrase in its title for the platform as a whole, linking findings, exploits, remediation and protection. The pages opened do not show how those four parts hand work to one another.
How Data Theorem handles your data
Data Theorem's privacy policy says it does not use information collected from customers to train third-party AI models, unless explicit consent or disclosure is required by law. Personal information is kept as long as necessary under its record retention policy, and deletion can be requested at privacy@datatheorem.com. The pages opened do not state a hosting region or name a certification such as SOC 2 or ISO 27001, so ask for both in writing.
Where Data Theorem falls short in practice
- Everything starts with a demo. The pricing page has no tiers, prices or free plan. A buyer cannot estimate cost or run a self-serve trial, so budget approval has to wait for a sales conversation.
- Thin public product detail. The page for API Secure returned a 404 during our check, and the AI features are named without explanation. Technical fit, such as supported API styles, has to be confirmed with the vendor.
- Compliance facts missing. No certification and no hosting region appeared on the pages opened. Regulated buyers need those documents before the tool can pass a vendor review. Without them a security questionnaire cannot be answered from public pages.

Alternatives to Data Theorem
Data Theorem: common questions
Does Data Theorem publish pricing for API Secure?
No. The pricing page opened shows no prices, no plan tiers and no free plan. It offers a demo request, so cost can only be learned by contacting the vendor. Plan any comparison against priced tools with that gap in mind.
What are ARCANE and AI Exploits at Data Theorem?
The vendor names AI Exploits as a feature in which ARCANE reads every verified finding across your apps and APIs. The pages we opened say nothing further about methods, accuracy or limits, so ask for a sample report. Ask for a sample report.
Does Data Theorem train AI models on customer data?
Its privacy policy says information collected from customers is not used to train third-party AI models, unless explicit consent or disclosure is required by law. The policy does not describe what happens inside the vendor's own models, so request that in the contract.
Where does Data Theorem host customer data?
The pages we opened do not state a hosting region, and they name no certification. The privacy policy lists a Palo Alto, CA address, but an office address is not a data location. Ask the vendor for region and audit reports.
Does Data Theorem list integrations?
None were named on the pages opened. The vendor does name SAST, SCA and SBOM as code security areas and its own AI features, but those are its modules, not third-party connections. Verify CI and ticketing support before buying. Ask which ticketing tools are supported.
