Hi!
I have a software that block unwanted apps or sites to intrude my system.
Why does this show from 1Password ?
The blocker is called Radio Silence.
I am a bit concern. It's on port 443
Thanks
John

    Hi @JohnDoe1983

    These are the domains we use through port 443, that you would need to white list.
    https://support.1password.com/ports-domains/

    You may also be interested in this blog post where we talk about some of server infrastructure, among other things. It will give a small glimpse behind some of the curtain.

    You may also like this one which is closely related. * Probably closer to the question your asking too. ;)

    If Radio Silence, is in active development? You may consider asking them to reach out to our developers.

    We have add descriptions for each outgoing connection type to a InternetAccessPolicyFile embedded in the app This would allow you to get a description of the connection attempt in plain language

    edit: typo and add additional link

    To add to what Tommy said above: It appears Radio Silence is looking at the hosts apps are trying to connect to, and then doing a reverse DNS lookup on those hosts. It is then showing you the result of that reverse lookup, which doesn't necessarily match what apps are actually trying to connect to. Other tools that do this sort of outbound connection monitoring show the forward DNS name that apps are trying to connect to, instead of the reverse, which is more likely to make sense to you.

    You can see what I mean yourself by running these commands in Terminal:
    nslookup my.1password.com

    3.208.193.188

    (this is one of the results)

    Then:
    nslookup 3.208.193.188

    ec2-188-193-208-3.compute-1.amazonaws.com

    You'll see this with all sorts of DNS records, not just 1Password's. Do the same experiment with google.com.  I guarantee that whatever IP address google.com resolves to, when you do a reverse lookup on it, isn't going to return google.com. It is going to return something like lga34s18-in-f14.1e100.net.

    This is totally normal and not any indication of a problem, though I would suggest that Radio Silence showing the forward lookups would be more useful to you than showing the reverse lookups. I hope that helps!

    I am waiting for an answer from a tech at 1 Password, will keep the follow up here upon receiving it.
    They installed Radio Silence and saw the same thing as I did.
    Thanks

    Hi
    What I like about your software is that anytime I have a question, I get an answer.
    You should teach some company how to deal with customer service.
    Thanks again. Very appreciated.

    John.
