AltostratusHow to block web site technologies information with ASM/Advance WAF
Hi,
How can we block what technologies are used on our website on ASM to protect web-sites like buildwith.com.
Thanks.
Hi pinkzeppelin,
it is difficult to block sites like builtwith or wappalyzer from profiling your web application.
builtwith offers a site for removing your site data: https://builtwith.com/removals
wappalyzer offers some guidance how to hide the technologies you are using from their scanner: https://www.wappalyzer.com/articles/how-to-hide-technologies-from-wappalyzer/Also F5 offers some guidance and also some information on why it is difficult to hide your technology: K35304481: Is there any way to prevent ''Wappalyzer'' from detecting my server technology by F5 ASM?
These tools are often using your browser for profiling the technologies of a website. Webservers, frameworks and CMS can be easily identified by Headers, file extensions or cookies. You cannot identify these tools by their user-agent or source IPs. Best you can do is to hide and obfuscate your technology stack.

pinkzeppelinThank you Daniel_Wolf .
Gajji Irule is the only solution I guess.

Daniel_Wolf Irule can not help in this case?
Irule to inspect the HTTP headers of incoming requests and blocking any requests that contain information about specific technologies.
- Daniel_Wolf
I would not know how iRules can help. Both, wappalyzer and builtwith, either come as a browser plugin or they offer an API.
The browser plugin creates a profile of your web application and its technologies from the HTTP responses that your browser gets, it does not add extra requests or headers. You won't even notice that a visitor has it installed in his or her browser.

OK need to test then with few cases in hand
