Features

• Declarative Access Control - Centralizes access control logic across applications and infrastructure to ensure consistent security decisions.
• Authorization Services - Acts as a centralized authorization service that evaluates structured input data to make consistent access control decisions.
• Policy-As-Code Engines - Provides a declarative language and framework for defining, testing, and versioning security and operational policies as code.
• Policy Engines - Enforces security and operational standards across infrastructure, microservices, and CI/CD pipelines in cloud-native environments.
• Infrastructure Policy Enforcement - Automates compliance checks for cloud resources and configuration files to prevent security vulnerabilities.
• Microservices Security - Intercepts and validates network requests at the service level to enforce fine-grained access control.
• Policy Propagation Systems - Synchronizes policy sets and configuration data across multiple instances to maintain a consistent authorization state.
• Policy Enforcement Engines - Automates code analysis within CI/CD pipelines to verify compliance with security and operational standards.
• Logical Condition Evaluators - Processes structured input data against high-level rules to generate consistent authorization decisions.
• Policy Distribution Systems - Synchronizes sets of versioned policy modules and configuration data across distributed instances to ensure consistent enforcement at scale.
• Sidecar Proxies - Deploys alongside application services to intercept network traffic and perform local authorization checks.
• Security Policy Enforcers - Provides language-specific tools and network interfaces to embed policy enforcement logic directly into diverse software stacks.
• Dynamic Policy Evaluators - Exposes a programmable HTTP interface for real-time authorization queries and validation of actions.
• Infrastructure and Orchestration - Unified policy enforcement for cloud-native environments.
• Microservices - Policy engine for microservices.
• Policy as Code - General-purpose engine for unified policy enforcement.
• Access Control Frameworks - General-purpose decision engine for policy enforcement.
• Expression Languages - Uses a specialized logic programming language to express complex authorization rules as declarative constraints.
• API Query Interfaces - Exposes programmatic API endpoints for external services to query authorization decisions and validate actions in real-time.
• Dynamic Policy Refreshers - Allows for the dynamic creation, update, and removal of policy files without requiring service restarts.
• Network and Infrastructure Security - Hooks into proxies and infrastructure tools to evaluate configuration and traffic against defined security and compliance rules automatically.
• Policy Validators - Provides testing and debugging tools for declarative policy code to ensure rules behave as expected.
• Execution Tracing - Generates detailed step-by-step explanations of policy evaluation to assist developers in debugging logic and understanding decision paths.
• Document Stores - Provides capabilities to retrieve, create, and modify structured data documents to support complex policy evaluation.
• In-Memory Databases - Maintains structured input and policy data in memory to enable high-performance lookups and rapid evaluation.
• Intelligent Development Assistants - Provides real-time feedback, code completion, and navigation features through a language server.
• Contextual Data Injection - Supports injecting and updating contextual information at runtime to enable dynamic, data-driven authorization decisions.
• Metric and Performance Monitors - Collects and reports granular timing and cache statistics to identify bottlenecks and optimize policy evaluation performance.
