Ivanti Pulse Secure VPN is apparently using CentOS 6.4

It seem popular in corporate environments to just rely on vendors and their binary blobs.. not at all surprised to see such findings.
Sure NOW there is zscaler and cloudflare tunnels and wireguard, but those are fairly new and companies don't want to rip out gear “that works”
Ivanti is a large company that "makes" VPNs, MDMs,patch management apps etc... Not just pulse secure VPN.
I say "makes" as the VPN was originally Juniper, the patch program they have was Shavlik. So they BUY IT enterprise companies when the VC money runs out or founder wants to exit.
That was the orginial name
