Gain Total Infrastructure Visibility

OSSTMM-aligned methodology ensures no part of your infrastructure is left unmapped or unmonitored.
OUR APPROACH

Targeted assessments tailored to your infrastructure

Our experts deliver comprehensive testing using network scanning tools, exploit frameworks, and manual techniques to identify and exploit vulnerabilities in internal systems:

  • Conduct host discovery and port identification using tools like Nmap, Naabu, and Masscan to map the internal attack surface.
  • Utilize tools such as Nessus, Nuclei, and Metasploit to detect misconfigurations, insecure network services, and weak encryption methods.
  • Perform deep-dive testing on visibly open services, including Active Directory (AD) servers, Domain Controllers (DC), and SMB servers.
  • Evaluate weak password policies, Kerberos vulnerabilities, and misconfigured trust relationships.
  • Enumerate SMB servers to exploit common flaws like disabled message signing, null sessions, and weak authentication.
  • Execute checks for the presence of Common Vulnerabilities and Exposures (CVEs) in utilized libraries and frameworks.
  • Get findings in real-time via the Cobalt platform, including step-by-step remediation guidance.
