Secure By Design.
Made Simple.
Aranya is an edge-native embedded software toolkit for building resilient, secure controls directly into applications and systems, enabling teams to define custom security policies with the Aranya DSL and enforce them alongside the resources they protect without centralized infrastructure or dependencies.
Security Controls Where They Matter Most
Aranya puts security controls adjacent to the resources they protect, enabling developers to embed identity, access, encryption, and policy enforcement directly into their commercial solutions.
Instead of relying on third party security products and network security, Aranya provides the building blocks to make security part of the architecture from the start.
Built for Developers. Engineered for the Edge.
Aranya provides an embedded toolkit for creating secure, centralized or decentralized applications that continue operating across constrained, disconnected, and contested environments.
Aranya DSL
Define custom security policies as code and decouple policy from implementation, making controls easier to build, maintain, audit, and update.
Edge-Native Controls
Co-locate controls with system resources so identity, authorization, and policy decisions can be enforced where operations actually occur.
Decentralized by Design
Eliminate dependence on centralized servers for critical security decisions and maintain trusted operations when connectivity is degraded, intermittent, or unavailable.
Everything You Need to Build Resilient Controls
Aranya provides the core capabilities developers need to build secure, resilient applications that maintain trusted operations across distributed, constrained, and disconnected environments.
Strong cryptographic identity
Unique identity creation for user, device, or resource resilient with attached policy based controls and lifecycle governance including revocation.
Asynchronous end-to-end encryption
Protect data across distributed applications without requiring continuous connectivity.
Automatic many-to-many state synchronization
Keep distributed state synchronized across authorized nodes and resources.
Low overhead & lightweight
Less than 500KB of RAM and less than 2MB of storage.
Serverless architecture
Remove centralized infrastructure, dependencies, and single points of failure.
Network disruption tolerant
Continue authorized operations when networks are offline, partitioned, or degraded.
Written in Rust
Built on a memory-safe systems programming language designed for performance and reliability.
Low latency
Line-rate encryption with enforcement decisions requiring fewer than 100 instructions.
Network and OS independent
Embed controls across heterogeneous systems without tying your architecture to a specific operating system or network.
One Toolkit.
Multiple Mission-Critical Use Cases.
Aranya gives developers a unified toolkit for securing applications with data-level microsegmentation, cryptographic identity and access controls, and automatic state synchronization.
Designed for disrupted and disconnected environments, Aranya allows authorized nodes to continue operating independently and securely synchronize when connectivity returns.
Build Faster. Operate for Less. Adapt with Confidence.
Reduce Risk
Shrink attack surfaces and improve breach containment by enforcing granular controls directly alongside protected resources.
Accelerate Development
Reduce development cycles and costs by separating security policy from implementation, simplifying how security is built, deployed, and maintained.
Increase Availability
Maintain secure system operations through network disruptions, partitions, and infrastructure failures.
Meet Compliance
Adapt policies as requirements evolve while maintaining built-in auditability and cryptographically verifiable controls.
