Challenge
The challenge was to deliver cutting-edge real-time systems that perform flawlessly under heavy workloads without sacrificing maintainability or security.
Our customers rely on these systems to process and transmit substantial volumes of data with predictable latency, supporting mission-critical operations in highly secure environments where system failures or data compromise could lead to significant operational consequences. These systems are long-lived, necessitating robust code architecture, comprehensive documentation, and automated testing frameworks to maintain security integrity and operational reliability as business requirements continue to evolve.
Infoserv’s solution was to harness modern Rust development. Rust’s predictable latency and strong memory safety allowed us to design and deliver real-time systems that are fast, reliable, and safe. Our approach - embed documentation, automation, extensive testing, and security into every stage of delivery, ensuring customer systems are secure, maintainable and meet business expectations and need.

Solution
Innovation in Rust for Real Time Audio Processing
For a national security customer, Infoserv built a Rust-based system capable of ingesting one hour of audio in just 30 seconds while maintaining end-to-end latency of under five seconds for real-time streaming. Rust’s ownership and borrowing model prevented memory leaks and concurrency bugs, ensuring stability under heavy workloads.
Alongside this, Infoserv created one of the first Rust APIs for the Silero Voice Activity Detection (VAD) neural network. Delivered in under two months, it enabled fast, secure integration of neural network models and demonstrated Infoserv’s ability to innovate rapidly with emerging technologies.
Long-Term Maintainability through Documentation
Infoserv delivered layered documentation — from architectural models and requirements documentation through to inline code comments and auto-generated references. This ensured both current and future developers could quickly onboard, prevented repeat mistakes, and aligned stakeholders on objectives and scope.
Rigorous Verification and Validation
Infoserv adopted a risk-based approach to verification and validation, prioritising tests around the most critical functions and customer needs. Automated test suites were continuously
expanded, while wider test sets were run before releases to provide confidence at each stage. This reduced wasted testing effort while maximising reliability where it mattered most.
Continuous Integration and Delivery (CI/CD)
Infoserv implemented Jenkins pipelines to automate builds, testing, version increments, and secure deployment of Docker images into Kubernetes environments. Helm chart updates and “pass” checks ensured only validated features reached production. This automation reduced manual effort, minimised errors, and let engineering teams focus on delivering value.
Security by Design
The result was hardened systems designed to resist threats from day one. Infoserv embedded secure coding practices such as strict input validation, applied encryption for data at rest and in transit, and enforced PKI-based identity management with certificate-based authentication. Vulnerability testing was carried out during development, identifying and resolving risks early. This proactive approach reduced the likelihood of security flaws reaching live environments.
