Secure Software Development
We can all see the value in the great shift-left, but where should you start.
Many orgs have goals for CI/CD controlled scanning, secure images, vaulted secrets and immutable infrastructure.
For others it’s best to start with the basics – scrubbing secrets from your images, and preventing accidental secret disclosure from git pushes.
Secure software development can lead to mutual benefits for the development and security organisations within your company.
Cybersecurity Education
Cybersecurity Education is by far the most effective tool you have to defend your company. Education isn’t a nice-to-have. Well trained employees can be a game changer for your security posture.
Sionnach provides Cybersecurity awareness and refresher training for all levels in your organisation.
