Faizan Nehal - PeerSpot reviewer
Platform supports skill development with effective vulnerability reporting
Everything has become slower on HackerOne. I have noticed that older researchers receive all the private invites while newer ones receive fewer. The same goes for real-life events, where the same people are invited repeatedly. There are no clear guidelines for being invited to programs and conferences, and the process for receiving invitations appears arbitrary.
AndyChan3 - PeerSpot reviewer
Enhanced visibility and exposes vulnerabilities but needs more integration
I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…

Cons

"Everything has become slower on HackerOne."
"Everything has become slower on HackerOne. I have noticed that older researchers receive all the private invites while newer ones receive fewer."
"Response time can be improved. The HackerOne Trust team can be slow to respond sometimes. They're not using AI, which could help reduce the number of duplicate reports."
"One issue I've experienced is traffic. Many people try to participate when an opportunity with a bounty of around 1,000-15,000 dollars comes up. In this case, the first person to report the vulnerability gets the bounty. If a second person reports the same vulnerability, they are marked as duplicated instead of receiving some recognition. The second person also invested time finding the issue, so I think this can be improved."
"The ability to view the conversation between the triagers and the programs will be really good."
"The integration is not as seamless compared to competitors like Palo Alto."
"Further integration across different Microsoft products would be an improvement."
"With Microsoft, support is always crazy, it's not easy to get support."
 

Pricing and Cost Advice

"The tool is open-source and free for bug bounty hunters."
