penetrators
Things that breach
Penetrators are things or people that penetrate—that is, enter, pierce, or pass through something.
The term appears most often in military and technical contexts: armor-piercing munitions designed to breach fortified targets, or specialized tools used in drilling and excavation.
In security testing, penetrators (short for penetration testers) are professionals who probe systems for vulnerabilities.
The word carries an inherently forceful connotation, suggesting deliberate entry into resistant material or defended space.
