Pentest
/ˈpɛn.tɛst/ · Noun · Verb · Security & Infosec
Definitions
Pentest, short for penetration test, is an authorized simulated cyberattack performed against a computer system, network, or application to evaluate its security posture by finding and exploiting vulnerabilities before malicious attackers do. Penetration testers (also called ethical hackers or white-hat hackers) use the same tools and techniques as real attackers, including reconnaissance, scanning, exploitation, and privilege escalation. Testing types include black box (no prior knowledge of the target), white box (full access to source code and architecture), and gray box (partial information). The process typically follows a methodology like PTES or OWASP and concludes with a detailed report documenting discovered vulnerabilities, their severity, evidence of exploitation, and remediation recommendations. Organizations conduct pentests for regulatory compliance (PCI-DSS, HIPAA, SOC 2), risk management, and security validation. Common tools include Burp Suite, Metasploit, Nmap, and Wireshark.
In plain English: Short for 'penetration test' — a simulated cyberattack performed by friendly hackers to find security holes before the bad guys do.
Example: "We pentested the new API last week and found three criticals."
