Michael Lynn, a man who earned a bit of infamy by exposing flaws in Cisco hardware at the expense of his job at Cisco, has found new work at Cisco competitor, Juniper Networks. Juniper does many network-based technologies including custom VPNs. Though it isn't told what position he's been given, suffice to say it probably has something to do with... security.

”Lynn gained the respect and attention of the security community by resigning from his former employer ISS so that he could present a talk on how it might be possible to run hostile code on Cisco routers, which until July were thought to be safe from such exploits.”
Sometimes, throwing a person to the wolves means them getting adopted by those very wolves. Some question how Cisco handled the situation, but Cisco has gone on record stating that the company followed standard procedures for information leaks.
