How is that a paradox?[1] I fail to see the contradiction in putting up a defense and yet remaining cautious. Did you instead mean that it is ironic? I don't find it ironic or paradoxical, but I think irony is closer to the word you're looking for.

Taking one precaution and yet remaining cautious is rather common. We wear seat belts, yet drive carefully. We practice good hygiene, and yet get vaccinations, etc.

I don't know but I think it is a paradox.

Here is why:

You put up a firewall to make you secure. So you should be secure. But by putting up a firewall you fail to secure something else or you are lax in another area of security. Because you think "it's been take care of. So I see it as a paradox. Although it could be ironic if someone put up a firewall but then was hacked because of something they didn't do thinking they didn't need it if they had a firewall. That would be an irony.
