In a challenging energy tech project, Sensetence was responsible for designing a central, highly complex authorization system in the backend. Our experienced senior developer contributed in-depth Symfony expertise within five months – and delivered a solution that went far beyond standard concepts.
The challenge lay at the heart of the project: different user groups – such as tenants, owners or administrators – should be able to view some of the same data, but always in the right context, under certain time conditions and with clearly defined data protection rules. Traditional role models are not sufficient for this. So we developed a multi-level access filter system based on Symfony voters.
Our system also enables time-based access: Access for certain user groups is only enabled in defined time windows – a detail that is not only technically demanding, but also ensures legal protection. All logic was validated throughout with unit and integration tests in PHPUnit to ensure quality and security with every adaptation.
The result makes all the difference: complete data control and GDPR compliance thanks to a sophisticated, maintainable authorization system. Centralized control of changes to rules or roles prevents uncontrolled distribution in the code, which significantly reduces maintenance costs. The system is also flexible enough to integrate new user roles without major conversion, data risks or demand logic.
In this case, our customer brought an experienced Symfony backend specialist into the team to implement precisely the security-critical components – in such a way that it remains robust, traceable and future-proof. Our client thus benefits from maximum security and scalability without having to outsource other parts of the project.
