A compressor is a machine that supplies pressurized air for tools or cleanup tasks. In workshops and hardware labs, it can power pneumatic tools or provide a stronger, steadier stream of air than a handheld blower or canned air. The key idea is simple: it stores or generates air pressure, then releases it when needed for cleaning, drying, or driving equipment.
In cyber security, compressors matter because many defenses start with physical maintenance. Security teams use pressurized air to clear dust from servers, fan cages, and exposed electronics during inspections, helping prevent overheating and making ports, labels, and tamper evidence easier to see. During incident response or hardware forensics, controlled air cleaning can also expose hidden residue or improvised hardware. Attackers with physical access may use the same tool to clean a device before probing it, but excessive pressure can damage components or drive moisture deeper into hardware, so careful use is important.
