Phases of a Pentest: Reconnaissance, Exploitation and Post-Exploitation
The stages that structure an intrusion test
An orderly pentest follows a logical sequence of phases that avoids wasting time trying random attacks. The reconnaissance phase gathers information about the target, from exposed subdomains to the technologies used, without interacting directly in an intrusive way; the scanning phase identifies ports, services and potential vulnerabilities across that surface; exploitation tries to confirm that those vulnerabilities are actually exploitable, gaining real access instead of stopping at a theoretical suspicion; and post-exploitation assesses what an attacker can achieve once inside, such as escalating privileges, moving laterally or accessing sensitive data, which is usually where the real business impact is measured. Skipping phases, for example launching exploits without proper reconnaissance, produces incomplete results and increases the risk of causing uncontrolled disruptions in production systems. Documenting each phase separately also makes it easier for the client to understand exactly how far a real attacker would have gotten.
