Features, pricing, ratings, and pros & cons — compared head-to-head.
Acunetix API Security Testing is a commercial api security tool by Acunetix. Data Theorem API Security is a commercial api security tool by Data Theorem. Compare features, ratings, integrations, and community reviews side by side to find the best api security fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Development teams and AppSec programs managing REST, SOAP, and GraphQL APIs across multiple environments should pick Acunetix API Security Testing for its ability to discover hidden and undocumented endpoints that standard scanners miss, then validate them at scale through continuous automated scanning integrated into CI/CD pipelines. The tool's IAST sensor delivers server-side context during testing, which matters when you need to confirm whether a detected vulnerability actually executes or stays theoretical. This is less valuable for organizations still building API inventory or those needing manual penetration testing depth; Acunetix assumes you know what you're protecting and want to run it fast and often.
Mid-market and enterprise teams managing APIs across multiple cloud platforms should choose Data Theorem API Security for its agentless discovery that actually finds shadow APIs without requiring agents deployed to every service. The platform covers the full NIST ID and PR functions,asset inventory, risk assessment, and runtime protection,which means you get both what's running and continuous monitoring of what it's doing, not just point-in-time scanning. Skip this if your APIs are mostly on-premise and behind mature WAF stacks; the value proposition is strongest when you're chasing undocumented endpoints across AWS, Azure, and GCP simultaneously.
