Selfhosted

Your work environment is bad if they are so easily distracted by branding and can't deal with 'unporfessional' and 'weird' things.

Sounds like you need to explain the difference between a serious tool and a serious looking tool. They can frump about it being weird but it is the foss option.

Look buddy I understand that URL has the same issue you mention in your post but it is the official Anubis URL.

Thus if you really want to be professional you load up the URL past the anime girl, organize a meeting and share your screen.

Tell them what it is and what it is for.

Explain what is opensource and the fact that this is free only if they accept that anime girl. Otherwise it'll be 50 bucks and they can put their own ai designed logo instead.

If they are still acting like childs treat them like childs. Recenter the meeting on what it is for. Do a proof of concept. I don't know, do something instead of stating that the official website is not how you would like it to be ?

Anubis is open source under the MIT license. If the branding is an issue, fork it, change the branding, call it good.

The MIT license makes it, effectively, a whitebox solution. You can change the branding to whatever you want it to be.

If your colleagues are people of a technical inclination they should understand that. If they don't I would question their competence and literacy. If they're not technical in nature I would question why any such proposal is reaching their desk without having first been rebranded, implemented in a test environment, thouroughly tested, and then (and only then) being presented as a proof of concept.

If this is for work you probably should bring in a professional. There are enterprise solutions for this.

This is selfhosted after all

If the UNESCO and Wikimedia websites can use it, so does your company. Not an issue of the software, grow up.

Idk my last workplace was full of nerds who appreciated the pedigree of anubus' creator. We used it to protect our production sites without even changing the branding. If I were in your place I would find it very hard to resist bringing up the amount of furries in tech.

Botstopper.

Litterly the same thing but you can customise the image.

You're a business, support the project.

Duckduckgo searching it, Botstopper, running Anubis in back and by the same author. I assume the website is theirs

I was asked by a different team how we can deal with bots

So they are not competent enough to do it on their own, but your solution gets laughed at? Why help them at all?

Let them allocate the budget for a "big boy" brand application firewall like F5 of paloalto...

I dont have a solution but I get it. My company ended up using slack over discord because of the same issue. Discord is unprofessional, the brand name and gamer logo were a nonstarter and that ended the discussion without looking at the software features.
