Frequent Deployments vs. Annual Penetration Testing: The Security Gap

The post states that deploying weekly results in 52 releases per year, while an annual penetration test evaluates only one of those deploys. This leaves 51 deploys untested at the time of the next assessment, which only identifies currently exploitable vulnerabilities, not those present for months prior. It also notes that the mean time to detection (MTTD) is approximately 180 days under an annual model, compared to 14 days with a sprint-cadence approach, and that fixing bugs early is six times cheaper.
