I am currently using Wiz, a scanning solution for cloud, to see if we are collecting reviews for any of these tools. My company has bought the license for Wiz, and we are using it as consumers.
HackerOne is used for bug bounty management. Whenever outsiders report any public-facing vulnerabilities or faults in our public-facing websites or domains, we receive a notification, validate it, and award bounties accordingly.
The ease of collaboration with ethical hackers on HackerOne has been quite good. From my experience, they respond when we do not have enough information on the findings.
Since starting work with HackerOne six months ago, we had other previous tools as well. HackerOne has been the right fit for our current situation.
