Developing a custom application: security from the ground up
With custom applications, security is not an extra that you add afterwards, but a design choice from day one. "Security by design" means that secure architecture, access management and secure code are part of the entire development process.
Security by design in practice
- Access management — roles and least privilege.
- Data minimisation — collect and retain only what is necessary.
- Secure code (secure coding) — prevent known vulnerabilities.
- Encryption — in transit and at rest.
- Logging & monitoring — detect misuse.
- Secure integrations — APIs with authentication.
Alignment with compliance
Does your application process personal data or sensitive data? Then security by design ties in directly with privacy (GDPR) and ISO 27001. We build custom solutions with these principles as the foundation.

Security by design means that security is built in from the very first design rather than bolted on afterwards. Think of secure architecture, well-considered access management, data minimisation, secure code and encryption. This prevents vulnerabilities from having to be repaired at great cost later on.
Not by definition, but custom development gives you full control over security and can be tailored precisely to your risks and requirements. Off-the-shelf software is widely usable but also a well-known target. What is crucial is that, in both cases, security is actively designed and maintained.
With maintenance: timely updates of frameworks and libraries, monitoring, periodic security checks and a process for handling vulnerabilities. Security is an ongoing process, not a one-off delivery.
