If you fail the network vulnerability scan in TrustKeeper, this means that the scan has discovered areas of vulnerability in your network of high severity. TrustKeeper will help guide you to remediate a failed scan and work toward achieving compliance. First, you'll want to login to TrustKeeper to review the scan results. The report will provide a description of the identified issues and resources to begin fixing the problems. You'll need to address each of the problems and then schedule a directed scan to ensure your remediation of the problem meets the PCI DSS.
