Hello Fidele,

I understand that you want to access 'shodan.io' and it was blocked as a hacking site. There are a couple of ways.

(a) you can override your URL filtering object and allow hacking sites.

(b) Depending on the PAN-OS, you can add one site in exception as a white list

(c) you can create a custom URL object and allow it.

(d) If you only want to allow for one user, you can create a policy based on the user, and URL 

some useful documents.

Yes this can be done or else add object as fqdn "shodan.io" and allow it in policy. But it will allow only 'shodan.io' but not *.shodan.io.

Thank you for response. Actually before i do anything, i d like to know if indeed it s hacking website as PaloAlto Firewall categorizes it. I am running PAN-OS 8.1.10

[SutareMayur]

Its not specific to PAN version. On my firewall (running on 9.0.3) also getting categorized under hacking site. I checked on few sites and reputation of this url is not listed as poor. Please check my earlier reply.

Visitors on our network can't access to the google drive from web anymore, the application on phone works fine. Anything that I can do about it?

Shodan is not a hacking site per se.  They will port scan all your addresses and will post what vulnerabilities they find.  Obviously, you do not want these advertised as the bad actors will use this database to prey on those who are vulnerable.  It is best to just block these addresses....but there are alot of them.  Some times its a bit of wack-a-mole as well.  There are other companies out there that do the same thing as Shodan (such as Digital Ocean).  

I would like to see Palo-Alto maintain a dynamic list for these shady characters.
