What is Security Testing?

Agencies that provide security testing support help teams turn goals into a structured plan with clear milestones. They typically start with discovery, evaluate existing assets, and identify gaps that limit performance. From there, they execute the work, monitor results, and adjust based on what the data shows. The best engagements include shared reporting, proactive communication, and a feedback loop that keeps priorities aligned. Rather than a single deliverable, security testing work is an ongoing program that evolves as market conditions change.
