If you landed on ie-g2.gumgum.com and wondered whether it's safe, here's what you should know. This URL is a subdomain of GumGum, a well-known digital advertising company. The page immediately forwards you to GumGum.com, which is a legitimate business with a long track record. Security checks show no malware or blacklist issues, and the connection is encrypted properly.
For a subdomain that handles ad tracking and asset delivery, it's normal not to find an about page or contact form here — that information lives on the parent site. However, if you're concerned about privacy, you should review GumGum's privacy policy on their main website rather than this specific URL. The lack of a privacy notice on this exact subdomain is a minor gap, but it doesn't make the site dangerous.
Overall, ie-g2.gumgum.com is not a scam. It's a technical part of a real company's infrastructure. If you see it in your browser's address bar, you're being redirected to GumGum, and that's fine. Just be aware that it's an advertising-related tracker, so any data collected would fall under GumGum's standard practices.
