Other Notable Modules

1. Attack Surface Monitoring

Attack Surface Monitoring is a feature within the Intruder Platform, but it is also offered as a standalone product. It is designed to help organizations identify and manage their digital attack surfaces, providing insights into potential vulnerabilities that could be exploited by attackers. The service includes an asset discovery feature that automatically discovers and maps all externally accessible assets, including websites, IP addresses, and cloud services.

This service provides proactive security, which helps organizations stay ahead of potential threats. The addition of threat intelligence prioritizes the most critical vulnerabilities based on real-world exploitability. Real-time alerts trigger if there is a change in the attack surface.

The system provides a complete view of all external assets, helping to identify shadow IT or forgotten assets that might be vulnerable. It also tracks changes over time, providing historical analysis that shows how the attack surface evolves.

The product is straightforward, making it easy for organizations to start monitoring their assets without needing extensive setup or configuration. However, you still need to have cybersecurity expertise to understand the data it gives you. The focus of the service is primarily on external assets, so organizations still require additional tools to monitor internal networks comprehensively. Another problem to remember is that, since it is cloud-based, the product’s effectiveness is tied to the reliability of the internet connection.

2. Compliance Reporting

The Compliance Reporting feature of the Intruder Platform helps organizations automatically generate reports to meet various regulatory requirements. This tool is especially useful for businesses in regulated industries such as finance, healthcare, and e-commerce.

Set up automated reporting so that the system generates compliance reports based on vulnerability scans, making it easier to meet requirements for GDPR, ISO 27001, PCI-DSS, and more. Users can customize reports to match specific compliance needs or to present data in a way that aligns with internal or external auditing processes. This ensures that organizations always have up-to-date documentation available for audits.

Automated report generation saves time and reduces the risk of human error in compiling data. Be aware that, while reports can be customized, the options might not be as extensive as some larger enterprises require. The tool is geared towards external regulatory compliance, and might not address all internal governance needs.
