Top pentesting software analyzed

Invicti

Invicti emphasizes the automation of web application security by providing dynamic and interactive application security testing (DAST and IAST). A standout feature of Invicti is its Proof-Based Scanning™ technology, which automatically verifies detected vulnerabilities to reduce false positives and provides proof of exploitability, especially for vulnerabilities related to REST, SOAP, and GraphQL APIs. 

It is designed for large enterprises and is scalable enough to handle extensive web applications and APIs across different environments. Users emphasize Invicti’s convenient features, especially its ability to verify access and SSL injection vulnerabilities and its compatibility with various security tools. ¹

Pros

• Invicti enables web application vulnerability scans and has a straightforward user interface.
• Invicti provides detailed remediation guidance for vulnerabilities and supports complex web application architectures.
• The tool features low false positive/negative rates, script injection per request, and supportive customer service.

Cons

• Invicti’s licensing process tied to URLs is strict, making it difficult to retrieve licenses in case of errors.
• The software lacks support for 2FA or MFA applications and can slow down during web scanning processes for larger applications.
• Invicti’s high resource consumption can lead to system slowdowns.

Cons

• Users find Burp Suite’s interface complex and challenging to master, requiring substantial study to understand all functionalities.
• The community version restricts certain features, nudges users to upgrade to the pro version, and excludes some basic features.
• Users report dissatisfaction with the reporting feature, issues with log separation, constant configuration changes for certain browsers, and a high number of false positives.

OWASP ZAP (Zed Attack Proxy)

As an OWASP project, ZAP is open-source and developed by the security community, making it highly accessible and community-driven. It includes an automated scanner that helps find security vulnerabilities in web applications during the development and testing phases. Users cite that OWASP ZAP is user-friendly for beginners.³

Additionally, it supports both active scanning, which attempts to exploit vulnerabilities, and passive scanning, which involves observing network traffic to identify issues.

Pros

• OWASP ZAP is completely free and open-source, making it an accessible tool for both individuals and organizations looking to perform web application security testing without licensing costs.
• The tool is designed with a simple and intuitive GUI, enabling users with varying levels of expertise to effectively identify vulnerabilities in web applications.
• OWASP ZAP benefits from an active community that contributes plugins, tutorials, and regular updates, ensuring the tool stays relevant and versatile.

Cons

• While suitable for small to medium-sized projects, OWASP ZAP may face performance challenges when scanning large, complex web applications.
• The reporting features are basic compared to some commercial alternatives, which may require users to perform additional analysis or formatting for client-facing reports.
• OWASP ZAP occasionally struggles to handle advanced frameworks, dynamic content, or single-page applications (SPAs) built with technologies like React or Angular, leading to incomplete vulnerability detection.

Tenable Nessus

Nessus is primarily known for its vulnerability scanning capabilities. It offers a wide range of plugins that automatically update to address the latest vulnerabilities, providing coverage across various devices and software. Users observe that the tool’s plugins are regularly updated to include the latest vulnerabilities and offer suggestions for remediation.⁴

Additionally, Nessus includes features for configuration auditing, compliance checking, and patch management, enhancing its utility to ensure adherence to industry standards and security best practices. 

Pros

• Nessus is known for its extensive database of plugins, enabling detailed vulnerability assessments across a wide range of systems and devices.
• Supports a wide range of operating systems, devices, and applications, ensuring broad coverage.
• Easily integrates with security information and event management (SIEM) systems and other security tools for enhanced workflows.

Cons

• The Professional version of Nessus can be costly for smaller organizations or individual users.
• Scans can take a significant amount of time or strain network resources in large-scale environments.
• Nessus focuses on detection rather than exploitation, making it less suitable for full-fledged penetration testing.

Metasploit Pro is a tool that prioritizes risks and demonstrates vulnerabilities through a closed-loop validation system. Additionally, it evaluates security awareness by conducting simulated phishing email campaigns. Metasploit specializes in creating and managing payloads that exploit vulnerabilities.

Metasploit Pro and the open-source Metasploit Framework should not be confused, as one is a paid pen-testing tool while the other is a free framework.

Pro Features that are not available in Metasploit Framework:

• Task Chains
• Social Engineering
• Vulnerability Validations
• GUI
• Quick Start Wizards
• Nexpose Integration

Metasploit Pro UI ⁵

Pros

• Metasploit contains a database of user-adjustable exploits and can connect to other security tools, aiding vulnerability testing.
• Metasploit provides pre-installed exploits in Kali Linux, offering accurate results for penetration testing and large scale exploit automation.
• Metasploit supports the creation of custom payloads, making it a versatile tool for penetration testing and vulnerability analysis.
