The Challenge of Traditional RADIUS
Traditional, on-premise RADIUS deployments have long been a source of complexity and frustration for network operators. They often suffer from a common set of problems that create risk and limit growth:- Scalability Bottlenecks: A single server can only handle a finite number of requests before performance degrades, creating a ceiling for user growth.
- High Availability Risks: A hardware failure or software crash on a monolithic RADIUS server can bring your entire network’s authentication to a halt, creating a critical single point of failure.
- Geographic Latency: A centralized server in one region means users in other parts of the world experience slow, frustrating login times.
- Intense Maintenance Overhead: Teams spend valuable time patching servers, managing hardware, and manually configuring redundancy, diverting resources from innovation.
- Lack of Modern Tooling: Most legacy RADIUS systems lack robust, developer-friendly APIs, making integration with modern billing, provisioning, and management systems difficult and brittle.
Altostrat Arc: RADIUS Reimagined
Altostrat Arc was built from the ground up on a cloud-native, serverless architecture to solve these challenges. We handle the infrastructure so you can focus on building and managing your network policies.Limitless Scale
Arc’s serverless architecture automatically scales to handle millions of users and thousands of requests per second without any performance degradation. Add unlimited accounts with confidence.
Global Low Latency
