It is critically important that organizations take a holistic approach to information security. Network security is all about understanding weaknesses and taking the steps to secure those weaknesses.

ISGRM Group provides your organization with a clear understanding of the risks present on your external network and with necessary awareness required to properly secure your organization's externally facing assets and help you move towards superior network security.

External Vulnerability Assessments are the backbone of our perimeter security offerings. Our security experts will run a series of tests to clearly define any vulnerabilities, identify possible threats that the vulnerabilities pose and provide detailed recommendations on how to fix any deficiencies. This provides realistic data and insights that can then be used to secure network equipment and defend against real-life attacks.


ISGRM Group offers external vulnerability assessments that are designed to look at the environment from the public view, that is, from the outside looking in. This is one of the first lines of defense for security on most networks.

ISGRM Group's External Vulnerability Assessment service follows the basic process outlined below:

  1. Receive signed vulnerability testing waiver from the organization
  2. Perform passive reconnaissance of the organization's external systems and presence
  3. Determine live hosts
  4. Conduct port scans of all live hosts (all scans will come from a predefined number of external IP addresses during a time that is mutually agreeable)
  5. Conduct vulnerability assessment using vulnerability scanning tools
  6. Verify vulnerabilities using manual scanning and verification techniques to eliminate false positives
  7. Write report of all vulnerabilities including remediation steps
  8. Review report with internal staff
