Real-Time Defense Across Your Application and API Stack

Protect your applications and APIs with continuous runtime monitoring, AI-driven threat detection, and real-time enforcement. Stop known and unknown attacks before they impact your business.

See API Runtime Protection in Action

Runtime Security Built for How Attackers Operate

Attackers chain business logic abuse, bot automation, and API-specific exploits together in real time, and AppSentinels detects and stops every stage of that chain before it reaches your business.

Stop Business Logic Abuse & Agent Manipulation

  • Continuous workflow learning: Builds a live baseline from real user journeys and usage patterns.
  • Business Logic Graph enforcement: Maps every session against expected sequences to flag manipulation instantly.
  • Context-aware anomaly detection: Adaptive detection replaces static rules and keeps pace with change.
  • AI agent behavior control: Stops coerced agents before unauthorized actions execute.

Block Bots, Fraud & Automated Abuse

  • Automated attack prevention: Stops account takeover, credential stuffing, carding, and scraping.
  • AI-driven bot detection: Tells real users from automated traffic, even as bots evolve.
  • Adaptive rate limiting: Thresholds shift dynamically with traffic and endpoint sensitivity.
  • Fraud pattern correlation: Links signals across sessions to catch coordinated abuse.

Defend Against OWASP API & Web Top-10

  • BOLA & BFLA protection: Enforces object and function-level authorization on every request.
  • BOPLA & mass assignment defense: Blocks property-level manipulation of restricted fields.
  • Web-layer attack defense: Built-in ng-WAF stops SQL injection, XSS, and SSRF in real time.
  • Continuous Top-10 coverage:Protection evolves alongside emerging OWASP risks.

Enforce Positive Security with Inline, MITRE-Aligned Controls

  • Schema-based request validation: Validates every request against your OpenAPI schema.
  • MITRE ATT&CK-aligned enforcement: Maps detections to known adversary tactics and techniques.
  • Real-time inline blocking: Enforces decisions in the request path, not after the fact.
  • Unified policy across surfaces: One policy layer covers APIs, apps, and AI agents.

Put Runtime Protection Between Attackers and Your APIs

Get continuous runtime monitoring, AI-driven threat detection, and real-time enforcement in one unified platform, built for APIs, applications, and AI agents.

Frequently Asked Questions

What is API runtime protection?

API runtime protection is continuous, real-time monitoring and enforcement that detects and blocks attacks against live APIs and applications as they happen. Unlike point-in-time testing, it analyzes every request, workflow, and user journey in production to stop business logic abuse, bots, OWASP API Top-10 exploits, and other threats before they reach your business.

AppSentinels builds a Business Logic Graph that continuously learns your application workflows, user journeys, and normal usage patterns. It uses this baseline to spot deviations in real time, such as skipped steps, abnormal sequences, or manipulated multi-step transactions, and enforces inline blocking without relying on static, pre-defined rules

Yes. AppSentinels detects and blocks account takeover, credential stuffing, carding, and scraping using AI-driven bot detection, adaptive rate limiting, and behavioral fraud correlation, stopping automated abuse before it impacts your APIs and applications.

AppSentinels provides runtime protection against the full OWASP API Top-10, including BOLA, BFLA, BOPLA, and mass assignment, alongside OWASP Web Top-10 risks such as injection, XSS, and SSRF, enforcing strict validation on every API request in real time.

A traditional WAF relies on static signatures and pre-defined rules, which miss business logic abuse and workflow manipulation. AppSentinels combines a built-in next-generation WAF for known attack patterns with continuous behavioral analysis and Business Logic Graph enforcement, giving you MITRE-aligned inline protection against both known and unknown threats in one platform.
