Platte River Networks (PRN) is the company managing Clinton’s private server. Due to a wave of hacking attacks on the server following the public revelation of the server on March 2, 2015, PRN considers doing penetration testing. That  means hiring someone to try to hack the server in order to expose its vulnerabilities so they can be fixed.

Cybersecurity expert Johannes Ullrich will later comment, “It’s a good idea, and it’s also commonly done.”

However, the penetration testing never happens. It isn’t clear why. (The New York Post, 9/18/2016) (Federal Bureau of Investigation, 9/2/2016)
