Just fyi, as a sysadmin, I never want logs tampered with. I import them filter them and the important parts will be analysed no matter how much filller debugging and info level stuff is there.
Same with network captures. Modified pcaps are worse than garbage.
Just include everything.
Sorry you had a bad experience. The customer service side is kind of unrelated to the technical practice side though.
It’s totally fine to bulk replace some sensitive things like specifically sensitive information with “replace all” as long as it doesn’t break parsing which happens with inconsistency. Like if you have a server named "Lewis-Hamiltons-Dns-sequence“ maybe bulk rename that so is still clear “customer-1112221-appdata”.
But try to differentiate ‘am I ashamed’ or ‘this is sensitive and leaking it would cause either a PII exfiltration risk or security risk’ since only one of these is legitimate.
Note, if I can find that information with dns lookup, and dns scraping, that’s not sensitive. If you’re my customer and you’re hiding your name, that I already invoice, that’s probably only making me suspicious if those logs are even yours.
