Application Security
API Secure
Agentless API discovery, security testing, and runtime protection across multi-cloud estates.
API Secure Overview
What it does
API Secure is an API Security service that continuously discovers an organization's full API inventory, including shadow and third-party APIs, then analyzes each API's health and applies runtime protection against more than 200 attack signals. Its distinguishing approach is fully automated, agentless blackbox discovery from the public perimeter, combined with cloud and API gateway consolidation, so security teams inventory and assess APIs across major cloud environments without deploying agents or instrumenting application code.
How it works
The service runs three coordinated functions: discovery, inspection, and protection. Automated blackbox scanning enumerates apps, APIs, and shadow assets across the external perimeter and consolidates inventories from existing API gateways and multi-cloud accounts. Discovered APIs are then tested with static, dynamic, and software composition analysis to surface vulnerabilities and sensitive data exposure before production. In production, the platform monitors more than 200 runtime signals spanning authentication, authorization, encryption, bot activity, and automated abuse, flagging leaky APIs and blocking attacks such as credential stuffing and AI-driven scraping.
Credentials and traction
In the 2025 Gartner Critical Capabilities for Application Security Testing, Data Theorem earned the top score for the cloud-native applications use case. API Secure is deployed by large enterprises and financial institutions, including Wells Fargo and 7 of the 10 largest banks, alongside Zoom, Coinbase, and eBay. Applications secured by Data Theorem collectively cover more than 2.8 billion users, and the service targets security and development teams protecting production API estates.
Key Capabilities
mapped to solution categoriesContinuously discovers and inventories all APIs across the environment, including shadow and zombie APIs that are not tracked in the official catalog.
Assesses inventoried APIs for misconfigurations and insecure implementations, such as endpoints that expose sensitive data or lack proper authentication.
Tests APIs for vulnerabilities using static and dynamic analysis, often integrated into the development pipeline before release.
Detects and blocks malicious API behavior at runtime using anomaly and behavioral analysis trained on attack patterns.
Detects and rate-limits automated abuse, credential stuffing, scraping, and misuse of sensitive business flows.
Identifies APIs that transmit or return sensitive data such as personal information, credentials, or tokens, so exposure can be flagged and controlled.
