Adding Security to Testing to Enable Continuous Security Testing
Teams can be trained by security experts to become able to identify areas to add security testing in the test process and add security checks as part of functional test automation. This can lead to continuous security testing where security defects can be spotted at an early stage with higher security testing coverage in every release.

Shifting Quality Left with the Test Pyramid
Shifting quality left means building in quality much earlier in the software development cycle, rather than testing for quality after completion of development. Using the test pyramid model, a project was able to move testing towards earlier stages, thereby finding defects that caused integration issues earlier in development.
