Probely, as a vulnerability scanner, will perform intrusive tests on your target while scanning for vulnerabilities. These tests can also be seen as a malicious attack. Therefore, we require you to prove that the target you want to scan is yours. In other words, we want to make sure that you are allowed to run security tests on your target domain.
You can verify the ownership of your target using two methods: DNS records or a TXT file. If these validation methods work for you, you can also request help with the validation process using the chat on this page.
