Building a
Secure Software Development Life Cycle
Build secure software – by design. Not as an afterthought.
Most security issues don’t arise from a lack of knowledge – but from a lack of structure.
If security checks happen too late, the result is delayed feedback, costly fixes, and frustration across teams.
A Secure Software Development Lifecycle (SSDLC) ensures that security is embedded from the start – across all phases of the development process.
It systematically integrates security measures, so that risks are identified early, actions are clearly defined, and results are verifiably documented.
At FullCyrcle Security, our goal is more than compliance. We care about making software actually more secure – with processes that work in practice, not just on paper.
Our Approach
Security integrated across the lifecycle
We help you integrate security into every phase of software development – from idea to production.
In each step, appropriate and realistic measures are implemented – tailored to your risk landscape, tech stack, and team structure.
This leads to:
This leads to:
- higher product quality
- increased process reliability
- and traceable compliance with regulatory requirements.
We don’t believe in theoretical models. We build practical structures – in collaboration with your teams.
What we offer:
- Maturity assessment & gap analysis
Understand where security is already integrated – and where the risk blind spots are - Architecture & process workshops
Define what security should look like across planning, design, build, and run – aligned with your delivery models - Security control definition & quality gates
Set clear expectations per SDLC phase – and define what needs to be tracked or verified - Tool evaluation & governance integration
Select and embed tools for testing, scanning, deployment, or policy enforcement – in a way that works for your teams - Feedback & rollout support
Support during implementation: from peer reviews to decision guidance and rollout planning - Documentation & audit readiness
Help in setting up documentation structures to meet compliance and internal assurance requirements - Developer Training: Tools are only part of the solution. The people of your organization are equally important for increasing the security of your software development. We offer basic security training based on the OWASP Top 10.
We collaborate with engineering, product and security – to turn concepts into working practice.

How to know if now’s the time
A secure SDLC is especially valuable if one or more of these apply to your organization:
- Security requirements are introduced inconsistently or too late
- Your security team is at capacity and can’t support all product teams effectively
- You face growing complexity in compliance or audit readiness
- Development has evolved (e.g. cloud-native, CI/CD, microservices), but security hasn’t kept pace
- Security is present – but not predictable or measurable
Whether you’re refining existing structures or starting from scratch:
A structured SDLC brings clarity, reduces uncertainty, and improves coordination across teams.
