Gitrob is a tool that scans public GitHub repositories for potentially sensitive files. It clones repositories and walks through their full commit history to flag files matching signatures for sensitive content, including files that may have been deleted in later commits. The tool presents its findings through a local web interface for interactive browsing and analysis. It serves results directly from memory without requiring a database, and allows users to save the full set of gathered findings to a JSON session file. Saved sessions can be loaded back into the web interface to continue analy

Attack Surface Analyzer can help you analyze your operating system's security configuration for changes during software installation.

Nettacker is an automated penetration testing framework designed to orchestrate reconnaissance, port scanning, and vulnerability detection. It functions as a network reconnaissance tool and vulnerability scanner that identifies open ports, fingerprints services, and checks systems against databases of known security flaws. The framework distinguishes itself by combining a web application crawler for discovering hidden paths via fuzzing with a vulnerability management system that persists scan results in a database to track historical assessments. It also includes specialized capabilities for

SEDATED® Project (Sensitive Enterprise Data Analyzer To Eliminate Disclosure)

Prowler is an automated cloud infrastructure security scanner and posture management tool. It evaluates cloud environments and infrastructure-as-code templates against security benchmarks to identify misconfigurations, vulnerabilities, and compliance gaps that could compromise system integrity. The platform distinguishes itself through graph-based attack path analysis, which identifies chains of misconfigurations that create exploitable routes for unauthorized access. It utilizes a plugin-based execution model to perform state-based assessments of live environments and static analysis of conf

Atomic Red Team is an adversary simulation tool and detection validation suite designed to emulate attacker behaviors. It functions as a security control testing framework that uses a library of portable tests to verify if security monitoring and alerting systems correctly identify specific malicious techniques. The project serves as a MITRE ATT&CK emulation framework, mapping individual test executions to a standardized industry taxonomy of adversary behaviors. This mapping allows for the validation of security controls against the MITRE ATT&CK matrix to identify gaps in detection and respon

RustScan is a high-speed TCP network scanner written in Rust, designed for security reconnaissance and network mapping. It functions as an automated port discovery engine that identifies open ports on remote hosts using IPv6 addresses, CIDR ranges, or bulk input files. The tool is built for rapid surface area discovery, utilizing parallel port processing and OS-aware performance optimizations to identify active services. It allows for scan precision tuning through adjustable connection timeout thresholds and concurrent request controls to balance speed and accuracy. The system integrates wit

a drop-in replacement for Nmap powered by shodan.io

gosec is a static analysis security tool designed to scan Go source code for vulnerabilities and common coding flaws. It functions as a security analyzer that inspects the abstract syntax tree to identify insecure function calls, API usage, and potential security risks. The tool distinguishes itself by mapping detected vulnerabilities to Common Weakness Enumeration identifiers for standardized reporting and integrating with external AI models to suggest code fixes for identified issues. Its capabilities cover the detection of injection vulnerabilities, hardcoded credentials, weak cryptograph

SpiderFoot is an open-source reconnaissance and intelligence automation framework designed to streamline the collection and correlation of data for security investigations. It functions as a comprehensive platform that automates the querying of hundreds of public data sources to map digital footprints, identify exposed assets, and uncover potential security threats across an organization's external perimeter. The platform distinguishes itself through a modular, plugin-based architecture that executes data gathering tasks in parallel, supported by a directed graph data model that tracks relati

Nikto is an open-source HTTP security auditing tool and web server vulnerability scanner. It functions as a reconnaissance engine designed to identify insecure server options, outdated software, and common vulnerabilities by analyzing HTTP responses. The project differentiates itself through capabilities for intrusion detection evasion and web server fingerprinting. It uses request-level encoding and timing spacers to bypass security filters and employs signature-based identification to determine specific server software versions and misconfigurations. The scanner covers broad capability are

Using a pre-commit hook, Talisman validates the outgoing changeset for things that look suspicious — such as tokens, passwords, and private keys.

Fast GitHub recon tool. Scans for leaked secrets across all of GitHub, not just known repos and orgs. Support for GitHub dorks.

Trufflehog is a security tool designed to continuously monitor code repositories and cloud environments to detect, verify, and remediate exposed sensitive credentials and API keys. It functions as a comprehensive secret scanning engine that integrates directly into deployment pipelines and version control systems to intercept sensitive data before it is committed or pushed. By utilizing read-only operations and volatile memory processing, the system ensures that discovered credentials are never stored persistently, maintaining strict data privacy throughout the scanning lifecycle. The platfor

Use SQL to instantly query secrets and more from source code. Open source CLI. No DB required.

detect-secrets is a modular secret scanning tool that identifies hard-coded credentials and sensitive information in source code. It combines multiple detection strategies—regular expression pattern matching, Shannon entropy calculation, and a machine learning classifier—to find potential secrets, and uses a baseline-driven delta analysis to distinguish newly introduced secrets from pre-existing ones, reducing noise from legacy credentials. The tool integrates directly into development workflows through a git pre-commit hook that blocks commits introducing unbaselined secrets, and can be inco
