Rethink Security.
Make Everything Invisible.
We believe that people, entities, and things—including AI—should connect securely and directly, while being invisible to bad actors.
They can’t attack what they can’t see.
Security that moves with people, entities, and things—not the network.
The atPlatform is an open-source, full-stack platform for developing applications and services that prioritize security, privacy, and data control.
Our Unique Security Triad
How atPlatform Protects What Matters
Protecting Data and Access
Securing Organizations, Governments, and AI Systems
Entities—including businesses, government institutions, and AI-driven infrastructure—require secure data exchange and controlled access. The atPlatform enables seamless collaboration without exposing sensitive data to the network or relying on centralized control.
Protecting Connected Devices, Infrastructure, and Technology
From IoT devices to industrial systems and cloud infrastructure, connected technology is constantly at risk. The atPlatform secures devices, APIs, and data flows without relying on network-based protections—ensuring continuous security, even in untrusted environments.
Security that checks every box
Federated Data Security
Enable secure collaboration without exposing raw data. The atPlatform’s federated security model allows people, entities, and things to share insights while ensuring data remains private, encrypted, and access-controlled. With Zero Trust principles and cryptographic verification, businesses maintain data sovereignty across hybrid and multi-cloud environments.
Policy Enforcement
Streamline security operations with human-readable, auditable policies that automatically enforce access controls. By shifting from network-based trust to Policy as Code, security follows data, not infrastructure—reducing overhead, enhancing compliance, and ensuring fine-grained control across AI, devices, and people.
Distributed Data Security
Security should move with your data, not be restricted by networks. The atPlatform eliminates centralized data vulnerabilities by ensuring data stays encrypted, decentralized, and always accessible only to authorized entities. This reduces attack surfaces, prevents large-scale breaches, and ensures continuous business operations.
Designed to scale with modern workflows
Distributed Architecture
Traditional security models create bottlenecks and single points of failure. The atPlatform eliminates reliance on centralized controls, enabling seamless, resilient security that scales across people, entities, and things—without network dependencies.
Privacy-First Architecture
Security should be private by design. Using confidential computing and end-to-end encryption, the atPlatform ensures data is never exposed—even while in use. Zero Trust principles eliminate attack surfaces, making security proactive rather than reactive.
High Availability
With just a snippet of code, you can easily integrate high availability into your applications and services—achieving 99.99% uptime from day one, without complex infrastructure management.
More Efficient Infrastructure
Rapid Deployment
Deploy security in minutes, not weeks. The atPlatform’s lightweight architecture eliminates complex configurations, enabling instant spin-up and seamless scaling. Security adapts dynamically as people, AI, and devices connect—reducing IT burden and speeding up business agility.
Reduce Costs
The atPlatform’s distributed architecture allows businesses to reduce costs, accelerate innovation, and maintain continuous operations. Scale services entirely independently, removing the need for unnecessary overhead—reducing overall energy consumption.
Increase Development Speed
Security should work the way you need it to. The atPlatform is open-source, event-driven, and adaptable—eliminating vendor lock-in, reducing tech debt, and automating security responses. Focus on building your product and stop worrying about networking and security.
