If every new feature means another workaround, the cost of older software is already reaching the business. Jolt helps replace the parts causing security risks, outages or expensive maintenance, while planning the transition around the services your customers and staff rely on.
Start with the problem: slow releases, unsupported software, recurring outages or systems that no longer connect properly. We work with the people responsible for the business and its IT to identify what should change first, what can stay, and how each investment will be judged.
We trace an important transaction through the system and identify its dependencies, security exposure and support costs. Architecture review and threat modelling turn that picture into a costed migration plan. Your team can decide which changes reduce the most risk or free the most capacity for new work.
A vulnerable C or C++ service may be a good candidate for Rust. Its memory-safety checks can prevent classes of errors that cause crashes and exploitable bugs. We retain the required interfaces and behaviour, review unsafe code and dependencies, and test the replacement. Rust addresses memory risks; access control and business logic still need their own checks.
Staff should use your company sign-in, with multi-factor authentication and only the access their role needs. We design service permissions, encryption and secret handling around that model. Security tests and dependency checks run before release, while audit logs help your team establish who changed what when investigating an incident.
Agree how much downtime and data loss the business can tolerate, then test recovery against those limits. We plan hosting capacity and costs, make environments repeatable with infrastructure as code, and establish monitoring and release controls. The operating team receives procedures for restoring service and clear ownership of alerts and support.
Industry research & examples
In a 2020 survey of 50 CIOs at large financial-services and technology companies, McKinsey found that technical debt absorbed 10–20% of budgets intended for new products. For Jolt, the first question is where maintenance is consuming your team’s time. We prioritise changes by that cost, the risk to operations and the features they make possible.
McKinsey · 2020 — Read the sourceGoogle reported in 2025 that medium and large Rust changes in Android had roughly a quarter of the rollback rate of C++ changes. That is evidence from one engineering environment, rather than a forecast for yours. It supports a practical option: use Rust for suitable high-risk services, then measure release stability and maintenance effort in your own system.

Your team receives a migration roadmap, acceptance criteria and operating documentation. Each stage has a release decision and a recovery plan, so the business knows what is changing and who is responsible.
Discuss your existing systemCapture business rules, interfaces and production behaviour before changing code. Agree the first service to replace and the evidence needed to accept it.
Where the architecture allows, route selected requests to the replacement while the original service remains available. Define API contracts and how data stays consistent during the transition.
Check business transactions, migrated records, security controls and performance under load. Rehearse cutover and rollback, including how to reconcile data written after the switch.
Move traffic in agreed stages and monitor errors, latency and business results. Hand over runbooks, alert ownership and recovery procedures. Retire old services only after acceptance and a reviewed recovery decision.
