Unified Policy Management for
the Cloud-Native Stack

Cloud-native and AI workloads span many layers. Reva unifies their policies into a self-learning authorization control plane enforced at runtime.

The Expertise Gap in Modern Infrastructure 

Modern applications and AI agents operate across multiple infrastructure layers, yet authorization remains siloed - driving complexity, risk, and operational drag.
Fragmented Policy Management
Teams must manage multiple policy models and languages (Rego, Cedar, IAM JSON) with no shared abstraction or lifecycle
Operational Overhead
Manual policy authoring is slow, brittle, and unable to keep pace with dynamic, 
AI-driven systems.
The "Black Box" Problem
Without centralized reasoning, access decisions are opaque—making audits and incident response painful. 

Security at the Speed of AI 

Policy sprawl undermines both security and scale. Reva replaces fragmented, expert-driven controls with a unified, self-learning authorization control plane—delivering consistent enforcement, adaptive guardrails, and centralized governance across cloud-native and AI-powered environments. 
Layer
The Problem
The Reva Solution 
API Gateway
Static rate limits and blind trust in authenticated tokens. 
Adaptive Trust Gateway: Dynamic runtime guardrails for APIs. Reva analyzes behavior and risk signals to auto-clip access and block anomalies in real-time. 
Kubernetes
Complex Rego/Gatekeeper management and configuration drift.
K8S Intelligence Guardrails: No-code Kubernetes policies expressed in natural language and enforced with continuous drift detection. 
Microservices
Hardcoded authorization logic that is impossible to audit or update.
Multi-Engine Authorization: Decouple authZ using OPA, Cedar, or AVP - governed centrally with explainable, low-latency decisions. 
Cloud IAM & Resources
Standing privileges and over-permissioned roles. 
Access Clipping & Governance: 
Continuously identify unused permissions and recommend clipped policies for zero standing privilege. 

API Gateways 

Reva centralizes API authorization into a single control plane -eliminating gateway-specific policy silos. 
Works across leading gateways including Amazon API Gateway, Kong and Apigee 
Runtime, context-aware authorization evaluating identity, parameters and real-time risk.  
Adaptive trust enforcement that dynamically clips, throttles, or blocks access without hardcoded rules.

Microservices 

Reva externalizes microservice authorization into a centralized runtime control plane. 
Compatible with Envoy, Istio and cloud-native service frameworks 
Multi-engine authorization support for OPA, Cedar and custom PDPs with <10ms P90 latency 
Consistent policy enforcement across services, meshes, and AI-driven workflows - without redeployment 

Cloud IAM, Resource
& Organizational Policies

Reva aligns cloud infrastructure policies with application and AI authorization in real time 
Unified across AWS IAM, resource, and organizational controls. Coming Soon – Support for Azure and GCP 
Continuous access evaluation correlating identities, resources, applications, and runtime usage   
Access clipping and governance to eliminate standing privileges and enforce least privilege dynamically

Rethinking Authorization for the Cloud-Native Era: Why Policy as Code is Your Answer
Traditional access models such as RBAC and PAM struggle in dynamic cloud-native environments. This post explores why modern systems require runtime, context-aware authorization and how Policy as Code enables scalable, fine-grained access control across microservices, multi-cloud architectures, and non-human identities.

Externalized Access Control at Enterprise Scale with Amazon Verified Permissions and Reva
As enterprises scale cloud platforms and API-driven architectures, authorization complexity becomes a major security and compliance risk. This blog explores how Amazon Verified Permissions (AVP) and Reva enable centralized, policy-as-code access control to address OWASP Top 10 and API Security Top 10 risks. Together, they help organizations enforce Zero Trust, reduce over-permissioned access, and modernize authorization with scalable governance and real-time visibility.
