===Network Associates acquisition===
In December 1997, PGP Inc. was acquired by [[Network Associates, Inc.]] ("NAI"). Zimmermann and the PGP team became NAI employees. NAI was the first company to have a legal export strategy by publishing source code. Under NAI, the PGP team added disk encryption, desktop firewalls, intrusion detection, and [[IPsec]] [[VPN]]s to the PGP family. After the export regulation liberalizations of 2000 which no longer required publishing of source, NAI stopped releasing source code.<ref>{{cite web |url=https://www.proliberty.com/references/pgp/ |title=Important Information About PGP & Encryption |publisher=proliberty.com |access-date=2015-03-24 |archive-date=January 28, 2022 |archive-url=https://web.archive.org/web/20220128002134/https://proliberty.com/references/pgp/ |url-status=live }}</ref>
