Penetration Testing (Pen Test)

A penetration test is an authorized simulated attack on your application or infrastructure, run by security professionals who try to actually break in — find and exploit vulnerabilities the way a real attacker would. It goes beyond automated scanners: a good pentester chains small weaknesses (an exposed endpoint, a weak permission check, a leaked key) into a real compromise, then reports findings by severity. For SaaS builders, an annual third-party pentest is a standard enterprise ask and a required control for SOC 2 Type II and ISO 27001. Buyers often want to see a summary letter, not the full report. Practical note: budget for a yearly test from a reputable firm once you have real customers, and scope it to your production stack. Fix critical and high findings promptly and keep the remediation evidence — that paper trail is what auditors and prospects actually want. A pentest is a point-in-time snapshot, not a substitute for ongoing security work.
