Web application development
Have a web application built that automates your work, speeds up processes and manages data securely. Secrotec builds custom web apps, customer portals, dashboards and internal tools — scalable for small and large, with security and access management built in from the foundation. As a security-first agency with an ISO background, we make sure your business data stays demonstrably secure.
What is a web application?
A web application is software that runs in the browser and that users actively interact with: logging in, entering data, processing requests or viewing data. Where a website mainly informs and convinces, a web application is interactive and process-oriented. Think of an environment where customers manage their files, staff handle requests or management sees real-time control information. Because data is processed and users log in, a web application requires more logic, access management and data security than an ordinary website.
Examples of web applications
- Customer portal — a secure environment where customers view documents, invoices or their file and arrange things themselves.
- Dashboard — real-time insight into figures, KPIs and progress, with clear reports for management and team.
- Internal tool — software that automates manual or error-prone work and supports your own processes.
- Request module — an online form or workflow through which requests, quotes or notifications arrive and are handled in a structured way.
- Reporting — automated overviews and exports that bring together data from various sources.
Our approach
We don't start with code, but with your process. In a short discovery phase we map out what the application has to do, who is going to use it and which data flows through it. This results in a clear functional design and a secure architecture. We then build in phases, often starting with a working core (MVP) that you can really use and that we then expand step by step. You retain visibility and control throughout: clear delivery points, interim demos and honest advice about what is and isn't worth building.
Security & access management
With a web application, trust stands or falls with security. We build security in from the foundation, not as an afterthought. In concrete terms that means:
- Access management — roles and permissions so that each user only sees and can do what is necessary (least privilege).
- Logging & monitoring — recording who does what, so that misuse and errors become visible.
- Input validation — all input is checked to prevent known vulnerabilities.
- Encryption — data secured in transit and at rest.
Does your application process personal data or sensitive data? Then this approach ties in directly with privacy (GDPR) and ISO 27001.
API integrations
A web application rarely stands on its own. We build secure API integrations with existing systems such as your accounting, CRM, ERP or email software, so that data is exchanged automatically without duplicate work. Every integration gets authentication and validation, so the exchange stays reliable and secure and your application fits seamlessly into your existing IT landscape.
Hosting & maintenance
After delivery we host and maintain your application via secure, managed hosting with back-ups and monitoring, supplemented with ongoing maintenance. Frameworks and libraries are updated in good time, we carry out periodic security checks and vulnerabilities are handled according to a fixed process. This keeps your application stable, fast and secure.
Scalable for small and large
A web application does not have to be large or expensive to deliver value. Smaller organisations in particular save a lot of time with a simple internal tool or request module. We build scalably: you start with what you need now and expand later without having to start over. If your organisation grows or users and features are added, the application grows with it — on a foundation that is prepared for it.

Frequently asked questions
Short, direct answers to the most common questions.
A website is mainly about showing information and informing or convincing visitors. A web application is interactive: users log in, enter data, process requests or view data. Think of a customer portal, dashboard or internal system. As a result, a web application needs more logic, access management and data security than an ordinary website.
Absolutely. A web application does not have to be large or expensive. Small organisations in particular save a lot of time with a simple internal tool, a request module or a portal that automates manual work. We build scalably: you start small and expand when needed, without having to start over later.
Yes, provided security is built in from the ground up. We apply access management with roles and permissions, validate input, encrypt data and keep logging to detect misuse. As a security-first agency with an ISO background, protecting business and personal data is our starting point, not an afterthought.
The cost depends on complexity: the number of features and user roles, the amount of custom work, integrations with other systems, the volume of data and the requirements for security and scalability. We first map out your requirements and processes, then give a clear price indication. We often start with a working core (MVP) that you can expand step by step.
Yes. We build secure API integrations with existing systems such as your accounting, CRM, ERP or email software. This way your web application exchanges data automatically without duplicate work, with authentication and validation so the integration stays secure and reliable.
Yes. A web application requires ongoing maintenance: timely updates of frameworks and libraries, monitoring, periodic security checks and a process for handling vulnerabilities. Through our secure hosting and maintenance packages we keep your application stable and secure. Security is an ongoing process, not a one-off delivery.
