Secure Software Development Lifecycle (SSDLC)

Secure software is not achieved through final testing alone, but by consistently addressing security requirements throughout the entire software development process. With the Secure Software Development Lifecycle (SSDLC), we integrate proven security practices into every phase of software development, from initial ideas and planning to implementation and production operations. This enables us to identify security risks early, systematically reduce vulnerabilities, and develop secure, reliable software solutions for the long term.

The Key to Secure Software

The Idea Behind the SSDLC

The Secure Software Development Lifecycle (SSDLC) is a structured approach that considers software security throughout its entire lifecycle. Unlike traditional software development processes, where security assessments often take place only at the end, the SSDLC incorporates appropriate security measures into the planning, architecture, and development stages from the very beginning.

How It Is Implemented

These security measures include threat modeling, secure coding standards, automated security scans, and regular testing. Even after deployment, the process continues with security updates, vulnerability monitoring, and ongoing improvements to the application.

The Goal

The goal of the SSDLC is to prevent or identify security vulnerabilities as early as possible, before they cause problems in production. This helps reduce risks, avoid costly rework, and improve the long-term security and maintainability of custom software solutions.

This is How We Develop Your Project Together

At first glance, a software project can seem very complex. We make your path to your desired software clear and easy to follow. Together, we start with your idea, develop a plan, and implement the solution. We also continue to support you during live operation and help you ensure that the application remains reliable and grows with your requirements.
1
Idea
Is your idea feasible? What costs can you roughly expect? What should you think about? Even before the first line of code, it is important to ask the right questions in order to steer development in the right direction.

2
Planning
Create concrete implementation concepts or carry out a proof of concept. Transparent communication, honest answers and an open exchange of opinions are important to us in order to create a robust concept together.

Is my idea feasible?

It depends!

So that we understand your goals and needs exactly, we ask a lot of questions at the beginning. For example, what purpose the application should serve, who uses the software in their day-to-day business and what added value it should achieve. We also clarify mandatory framework conditions in advance.

Goals and requirements
Clearly defining and naming goals is essential for a project:
  • Is it important to create a first version as quickly and cheaply as possible?
  • Is compliance with secure development and standardized processes important right from the start?
  • Should a proof of concept first be used to check whether two devices can actually work together technologically?
  • Is there already existing software and can it continue to be used?
We believe it is essential to clarify these and similar questions as early as possible.
Honest answers and assessments
After we have understood your goals exactly, we start with possible solution ideas. We point out risks, such as dependencies on cloud providers or the use of proprietary interface software. There are usually 'many roads to Rome'. In order to make an informed decision, it is important to know what alternatives there are and what the advantages and disadvantages are. This includes, in particular, a rough estimate of the costs and time required by us.
Check feasibility
The following terms all describe the same concept:
  • Proof of Concept
  • Minimum Viable Product (MVP)
  • Pilot project
  • Prototype
The idea or problem-solving approach is tested. It naturally depends on the size and complexity of the project whether testing makes sense.

How does it all fit together?

Planning and conceptual design

Which tools are best suited?
Tools refer to the programming languages, protocols and libraries that are to be used. We always use exactly the right tool for a task, instead of treating each task as a nail and working on it with the same hammer.
How much effort/cost is involved?
Do you perhaps need to buy a software license? If the application is to run in the cloud, costs are incurred. And: How much effort is involved in the actual programming? An important criterion for almost every project: the price.
How long does the implementation take?
Is there an important trade fair coming up for which an MVP (Minimum Viable Product) is to be presented? Does old software need to be updated because it is no longer supported? How many developer resources are available?
Think about operations too!
Processes, running costs and long-term support of an application are often completely underestimated at the start of the project. We take into account and communicate from the start what you will face when operating a software.

How we work

Let's Code

Secure development

The four-eyes principle for code reviews, an audited working environment and experience are the basis for the secure development of our code.

Sustainable code / Open Source

Consistent use of Open Source packages and clean code policies make our code durable and reusable in the long term, without reinventing the wheel and generating unnecessary effort.

Agile development

Clear and simple communication is the key to agile development between client and contractor. We are convinced of this.

Transparent feedback on development status

Regular feedback sessions with our customers are very important to us. This is the only way we can check whether the results delivered meet expectations.

Off to work

Think about operations

Maintenance / monitoring
Detecting errors and irregularities before something happens - the flagship discipline for any continuously running application. For us, this task is a matter of course.
Updates (security)
Externally used libraries, operating systems and other packages used require regular updates - we take care of it.
Tests and quality assurance
Pentests and regular manual and automated tests ensure the long-term quality of software. Completely error-free software does not exist in our universe - so we do not even sell this empty promise.
Application support
All applications require support. Whether research is needed in the data of a platform or the functions of the application need to be explained to users again: support requests are part of everyday life.
Extensions / adjustments
Software development is never truly finished. Change requests, refactoring, feature requests, and new integrations are constantly being added. This continuous evolution is essential for every software application.

Software service

Challenge? Accepted!

Outstanding services around Software development, support and consulting must provide answers to the six biggest challenges:

Time pressure

Decision-making processes often drag on for weeks and months. As soon as a decision has been made, things have to happen very quickly - you want to see progress as soon as possible (and rightly so!). More resources, more know-how, and quick results are required. Our developers are experienced in throwing themselves into every project without a lot of overhead work and quickly showing visible and yet sustainable results.

Old projects. Old code

Highly specialized programs in particular run quietly in companies for years or even decades. Until an adjustment is necessary - however: Nobody knows who developed the program, where exactly the data comes from or what the program actually does. We help: We analyze, evaluate and familiarize ourselves with the old source code. The code can then be expanded, secured or even completely rewritten in coordination with the partner.

Special security requirements

Secure software development is important to us. We believe that it is not enough to just work through compliance checklists. Criminals, hackers and sometimes competitors are not just theoretical threats. Highly secure software architecture and consistently protected software platforms are our speciality. For us, the requirements can never be high enough.

Permanent development partners

Most of our customers work with us as partners for years. They tell us their wishes and needs, we develop and advise on all topics related to software. Building trust, professionalism and consistently high quality are the pillars of our collaboration. Our lead developers are proud to quickly earn this trust with every new project.

Money Money Money

Lots of colorful features, highly secure development, a fully trained, 24/7 on-call development team and the product live tomorrow, ideally, with a new change every day. If the pot of money were infinite, we would do it without any problems. The reality of our partners is usually different. And we know that very well. We minimize costs right from the start, communicate openly, advise on which features are really necessary, how costs can be reduced by using Open Source, for example, which meetings really have added value and how much documentation is useful.

Let the idea become reality

With software, everything is possible. There are almost no limits to the digital world - the most successful companies in the world (the 'Big Five' such as Apple, Google, etc.) are based on an idea that became reality using software. Our job is to bring your ideas to life.
