I prefer to use a different company for my domains, as for other services--like Mail, Web, Hosting. Therefore, if something happens to one, it doesn't affect my other services. As you mentioned, you are from Germany. I can highly recommend https://INWX.de —I use them myself, and for hosting, I use Hetzner as well.

Another option in Germany is Key-Systems: https://www.key-systems.net/

No affiliation with them, but my personal domains are registered with a local Dutch registrar, who in turn registers some of them with Key-Systems.

I would take a moment to pause and consider the TLD if you're concerned with authorities taking over your domain. Various TLD (.com,.io,.pizza) have different polices regarding termination as well as different legal basis whether or not seizure can be exacted in a given jurisdiction.

I presume all this is for a legitimate business and thus any operator will do.

However, if you get a domain within the top 4-5 TLD (the original TLD of .COM,.NET,.ORG,.EDU,.INT/.MIL/.GOV), all of these domains are ultimately belonging to US incorporated entities or governmental organizations and not any UN operated office thus is not party to the UN charter and the legal avenues afforted to it.

Operationally there is .onion that is non-organizational for the TOR network as well as .I2P for Freenet.

So it may do you well that you get both .de and .com as well as any other .tld you are willing to spend and protect for your brand name as that's what alot of scammers/spammers and marketers will try to redirect traffic into due to mistyped characters. Also for legal/public campaigns that may be counter to your business direction or your client's.

One last thing: There is the whole DNS server aspect of a machine sending out answers to your infrastructure. The domain usually has a locking mechanism that procedually protects the domain from being transferred to another provider at whim. I would spring for the anonymization to prevent social engineering attempts as well as extend your DNS records into DNSSEC to ensure to the world that every answer or call back to your DNS records are flat factual answers that are cryptographically sound. DNS is one of the few things that helps control the chaos doesn't overrun the network.

And be sure to pay your bill on a multiyear basis with reminders at the CTO/CFO level - there is usually a 30-60 day soft hold after the domain expires but it's a regular occurrence with every corporation as to whether or not they catch domains that are important to their image or brand vs. ones simply forgotten and become swiped up for ransom or other possibly unwholesome pursuit.

Cheers!
