Finite State

Finite State is on the cutting edge of product security for connected devices—helping organizations understand and reduce risk across firmware, software supply chains, and IoT deployments.

As customer demand grew, Finite State needed an API that could deliver enhanced security capabilities and flexible scalability without disrupting the platform their customers already relied on.

"We needed a partner who could move fast on a complex API—without compromising the security and reliability our customers expect."

The Challenge

Security, scale, and demanding endpoints

Finite State's existing infrastructure needed a modern RESTful API layer that could extend functionality at each endpoint while meeting tight delivery timelines for a minimum viable product.

  • Large uploads. Firmware and artifact uploads required careful handling to stay performant and reliable at scale.
  • Data aggregation. Security insights needed to be composed from multiple sources without slowing customer workflows.
  • Request timeouts. Long-running analysis had to be designed so clients received predictable, resilient behavior.

augustwenty partnered with Finite State to create a strategic plan that leveraged their existing systems—building enhanced API capabilities while preserving a smooth path for customers during and after the transition.

Our Approach

A RESTful foundation built for real-world constraints

We invested in understanding project intricacies up front—mapping how each endpoint would be used, where data volume spiked, and which operations needed asynchronous or chunked processing.

That clarity shaped an implementation plan aligned to MVP delivery: solve the hardest endpoint challenges first, then expand client-facing functionality with confidence.

The team built a RESTful API on top of Finite State's existing infrastructure, adding enhanced security and scalability at each endpoint while keeping the developer experience consistent for internal and customer integrations.

Through meticulous execution, we addressed large uploads, data aggregation, and timeout behavior—turning fragile edge cases into dependable platform capabilities.
