How recruiters use these terms
Recruiters run Boolean searches that OR together title variants and AND them with must-have skills, then ATS platforms rank applications by how literally the resume matches the posting. That's why the exact product name, certification code, or title variant matters: "SIEM experience" doesn't match a search for a specific platform name, and a title variant you never carry is a search that never finds you. Work the honest terms into your headline, summary, skills block, and experience bullets — placement near the top of page one carries more weight than repetition.
