For awhile I’ve liked the idea of using a VPS for “critical” services. Currently looking at running:
- Authentik
- Komodo (with periphery agents on local boxes)
- Uptime Kuma
- NTFY
- Panglolin (or Cosmos Cloud?)
So, first of all, to folks already using a VPS, do you think it’s worth it? Do you think I’m missing anything? Happy to discuss/research alternatives, too. I’ve thought about TinyAyuth+PocketID in place of Authentik. While I think Authentik is probably more complex (and likely overkill), it’s a single solution. That said, I haven’t played with TinyAuth/PockedID.
Second, I was pretty interested in Pangolin until I saw Cosmos Cloud mentioned elsewhere. It seems like it actually ticks a lot of boxes:
- Built-in authentication
- Reverse Proxy
- VPN (At least for local-to-VPS connection, but possibly also for external clients?)
- Docker management(?): They have an “app store” that’s all docker images, so there’s some docker capability built-in. Not sure yet if it can handle multiple hosts like Komodo.
- DNS (I would still keep at least 1 local pi-hole instance)
Looking at the doc for chaining proxies and hiding IP, here, it mentions creating an A record for services hosted on a different server. I’m curious to know if this means Cosmos will only manage DNS for services hosted on the same box. Honestly this seems kind of odd, unless I’m misunderstanding how proxy servers work.
Anyway, I know this was a bit of a meandering post. Curious to know thoughts on my original plan, but also if anyone has played with Cosmos, I’d like to hear your thoughts.
Lastly: This morning, I found this interesting write-up to manage container updates using Forgejo, Renovate, and Komodo. Another rabbit hole to explore!

If you put any data anywhere, assume it will be contained in a breach in the future. Blue teaming is hard. You have to be perfect every time. Red teaming is easy. You just have to wait till the blue team makes a simple mistake…
Mails sent to a company? Their or your mail account will be breached one day.
Account details on a webpage? Their user database will be leaked.
Your cloud drive, ect.
Even your data on your NAS at home or on your PC could get accessed in one way or another, you’re just a zero day and an unfortunate click away from disaster.
On the upside, as long as you do not have a target on your back, patch your stuff in a timely manner and keep some hygiene in configs, secops … You should be fine, as most automated attacks aren’t that high level and target the low hanging fruits. But that doesn’t make you completely safe.
After 20 years in the field I’d say it’s an impossible job. We are always 5 steps behind. Now with AI, 27 steps. I quit IT to keep my sanity.
And don’t listen to the promises of big companies with billion-funds, they cook with water like the rest of us. See " Amazon infiltrated by North-Korea ".
Oh, yeah, I remember when one of our super important core systems was migrated to SaaS. My system was interfacing with it, so I got notified about the migration to make a plan. I basically told them: “We’re using $API to connect to your system. Tell me the new hostnames and IP ranges and ports and I will configure the firewall on our end. Also, our connector for your migrated system will be deployed in $IP-range so please allow these inbound connections in your firewall.”
Half a year later I got a message: “Yeah, we just found out, that $SaaS-provider never configured the firewall after our tickets and everything is reachable from the public internet. We’re forcing them to lock down the system now. Can you please tell us again from where you connect to us?”
That N Korea story was wild!
