March 2, 2015: The company managing Clinton’s server tightens security on the server after its existence is exposed.

On the morning of March 2, 2015, a front-page New York Times article reveals Clinton’s use of her own private email server. Platte River Networks (PRN) is managing the server.

Later in the day, PRN employee Bill Thornton writes in an internal company email, “I spent some time in their firewall just now locking everything down (pretty tight).” (The New York Post, 9/18/2016)

However, on March 4, 2015, an analysis of the server’s publicly visible settings will show it has a misconfigured encryption system. Further articles the next day will expose more security vulnerabilities.

PRN will make more changes to improve the server’s security around March 7, 2015.
