pock/pɒk/
One word. Some say P-O-C letter by letter.
A proof of concept is a short trial deployment where a prospect tests a cybersecurity product in their environment against predefined success criteria. POCs typically run two to four weeks and evaluate detection accuracy, false positive rates, integration with existing SIEM or SOAR tools, and operational overhead.
Why Proof of Concept Matters for Your Cybersecurity Career
POCs are standard in enterprise cybersecurity sales because buyers refuse to commit six or seven figures without testing in their environment. Sales engineers run POCs and ensure the product performs well against the evaluation criteria. A successful POC dramatically increases close rates and shortens the remaining sales cycle.
