Most security vulnerabilities in custom software are not the result of sophisticated attacks — they are the result of known issues never addressed because security was treated as someone else's problem. DevSecOps inverts this — security is integrated into every phase of the development lifecycle, from design through to deployment and operation.

Threat Modelling at Design Time

Before writing code, lightweight threat modelling identifies the assets that need protecting, the threats against them, and the controls that mitigate those threats. This takes a few hours and consistently surfaces design-level vulnerabilities expensive to fix after implementation — one of the highest-return security activities available to any engineering team.

Automated Security in the CI/CD Pipeline

Static Application Security Testing tools analyse source code for known vulnerability patterns on every commit. Software Composition Analysis tools flag vulnerabilities in third-party dependencies. These checks run automatically — catching issues early, when they are cheapest to fix.

Security as a Team Responsibility

Tools catch a lot, but not everything. Code review with a security lens — looking specifically for authentication issues, injection vulnerabilities, and insecure data handling — remains one of the most effective controls available. At Nuges Ltd, security is a standing item in every code review. Talk to us about securing your software systems.
