Featured Reviews

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.
Jos Badimo - PeerSpot reviewer
Test assurance improves compliance and products with good performance
The user interface could be improved to facilitate easier navigation. The most significant issue I encounter with the solution is the user interface. It would be beneficial if I could remain on one screen most of the time. Even if the system navigates me to another screen, it should effectively return me to the main screen.

Pros

"It helps me to get new sales, profits, and other benefits."
"HackerOne is larger than WebCloud and has a better reputation than BugCloud, which results in a smoother process."
"HackerOne is larger than WebCloud and has a better reputation than BugCloud, which results in a smoother process."
"Apart from getting all the bug bounty opportunities, we also get the chance to practice in a safe environment, like a demo setup. These features are great for beginners who want to explore bug bounties in the future."
"The most valuable feature of HackerOne is its variety of programs. These programs provide depth into various areas, such as mobile, API, and websites."
"Our customers use it to check for unauthorized file transfer."
"The testing compliance feature is particularly impressive."
"CyberFlood is flexible."
"The feature I find most valuable is the traffic generator."
"The testing compliance feature is particularly impressive."
"CyberFlood's best features are its user-friendliness and scheduling function."
 

Cons

"Everything has become slower on HackerOne."
"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."
"Everything has become slower on HackerOne. I have noticed that older researchers receive all the private invites while newer ones receive fewer."
"The ability to view the conversation between the triagers and the programs will be really good."
"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."
"The initial setup is not straightforward and can be quite challenging."
"The solution needs more ports, more speed, and more gigabytes."
"Sometimes, when you configure parameters the hardware can't run, it will get stuck at those points without telling you what happened. It would be helpful if the error reporting provided more details about why the test setting is not running. It would be nice if there were a space in the hardware module for you to add some external hardware for more rigorous testing."
"I would also like to see updates on a more frequent schedule."
"CyberFlood's accessibility and support for multiple browsers could be better."
"The user interface could be improved to facilitate easier navigation."
