PenPeeper
What it is
PenPeeper is an open source, on-premises system for organizing penetration testing engagements and preparing client reports. It guides work through Gather, Search, Findings, and Report, and supports multiple engagements and clients. Users can tag devices, filter assets, and import scans, screenshots, and notes. Built-in integrations include Nmap, Nikto, SearchSploit, WhatWeb, Enum4Linux, FFUF, and SNMP; scan concurrency can be configured. PenPeeper retrieves CVE details, severity scores, and descriptions from the National Vulnerability Database. Its AI features support vulnerability hunting, evidence examination, remediation recommendations, and executive summaries through local or cloud providers, including LM Studio, Ollama, OpenRouter, Claude, Gemini, and ChatGPT. Guided templates and customizable summary graphics are available for PDF reports, and projects can be exported as encrypted files. It is free for personal or professional use under its stated license terms. Its vulnerability checks are passive and flag potential issues for manual review.
