It is commonly estimated that up to 80 percent of all information security breaches are made possible due to the actions (intentional or unintentional) of insiders. An insider made be an employee, vendor, or anyone who has been granted any level of access to the internal network.
Internal penetration testing identifies the vulnerability level of your network to unauthorized access from within your organization. It identifies the information that could be compromised and the degree of difficulty required to exploit an identified vulnerability. Often discovered vulnerabilities include easily compromised passwords, insecure data exchange mechanisms, and exploitable file permissions and system configurations.
