My company has about 600 POS terminal out there and require regular internal scan for security purpose, most of POS terminals connect Internet via ISP modem given dynamic public IP. is there a cloud-based ddns service so that a agent install on POS will update their public IP with every x hours?

Seems like a horrible and insecure alternative to VPN tunnels, but whatever. There are plenty of public DDNS services out there.

No-IP.com's the popular choice.
Dyndns.com was one of the original players, but they've killed their free DDNS service, so they might be hurting and thus unreliable.
OpenDNS offers DNS services, and you could make the records dynamic by setting a low TTL. They're also configured for providing DNS services to businesses, so they should be able to absorb the load and provide "helpful" graphs if they become your primary DNS server.

Check your options with whatever device gets the public IP. That'll determine the services available to you.

Making all of your POS terminals available to all and sundry on the Internet doesn't sound like the best idea going. I would strongly urge you to reconsider.

Any chance you could let us know your company's name? I'd hate to think that any of my private details were held by them.

Professional courtesy is never asking for the employer. They're all horrible. Only by accepting those willing to learn can we avoid something worse.

compu-angus these POS units have to be using VPN's to make their corporate connections. Otherwise not only are the terminal vulnerable to attack but so is what they are connecting to.

The vpns will prevent you from what you desire.

Answers are only as good as the information you provide.
