  • Detailed reporting for both technical and executive audiences, including actionable remediation guidance and compliance reports (PCI DSS, HIPAA, OWASP Top 10)

Nmap (Network Mapper) is a powerful open-source tool that has become an industry standard for network discovery and security auditing. With its versatility and extensive feature set, Nmap enables organizations to gain deep insights into their network infrastructure, identify potential vulnerabilities, and assess the overall security posture of their systems.

One of Nmap’s core strengths lies in its ability to perform comprehensive host discovery and port scanning. By leveraging various techniques, such as ICMP echo requests, TCP SYN scanning, and UDP probing, Nmap can efficiently identify active hosts and open ports on target systems. This information is crucial for understanding the attack surface and identifying potential entry points for attackers.

Key features of Nmap include:

  • Flexible host discovery options, including ICMP echo requests, TCP SYN/ACK scanning, and ARP scanning, to identify active hosts on a network
  • Comprehensive port scanning capabilities, supporting various scan types (TCP SYN, TCP connect, UDP, etc.) to determine open ports and associated services
  • Service and version detection, employing a vast database of over 1,000 well-known services to identify running applications and their versions
  • Advanced OS fingerprinting, analyzing the unique characteristics of network responses to determine the operating system and hardware details of target systems
  • Scriptable automation through the Nmap Scripting Engine (NSE), enabling customized scanning tasks and vulnerability detection using a wide range of pre-written scripts
  • Detailed output formats, including XML, grepable text, and normal text, facilitating integration with other tools and easy parsing of scan results

StackHawk is a modern dynamic application security testing (DAST) tool designed to seamlessly integrate into the software development lifecycle (SDLC). With a strong focus on developer enablement and automation, StackHawk empowers engineering teams to identify and remediate vulnerabilities early in the development process, promoting a shift-left approach to application security.

One of StackHawk’s key differentiators is its deep integration with CI/CD pipelines and developer workflows. By providing a simple configuration file and supporting popular CI/CD platforms like GitHub Actions, GitLab, Jenkins, and CircleCI, StackHawk enables automated security scanning as part of the regular build and deployment process.
