Featured Reviews

Israel Cavazos Landini - PeerSpot reviewer
Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.
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.
NaySan @ Suraj Verma - PeerSpot reviewer
Provides actionable vulnerability insights and recommendations with notable efficiency
They may need to improve the portal refresh rate for Microsoft Defender Vulnerability Management because it takes time for recommendations to disappear after mitigation; sometimes, it takes one week, when it should ideally take only one to two hours. Overall, everything is good with Microsoft Defender Vulnerability Management, but the portal refresh rate can take up to seven days in some cases and three or four days in others to reflect changes.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

"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."
"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."

Cons

"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."
"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"Everything has become slower on HackerOne."
"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."
"Everything has become slower on HackerOne. I have noticed that older researchers receive all the private invites while newer ones receive fewer."
"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."
"It is expensive."
"Integration can be improved."
"The general support could be improved."
"Probably my only criticism would be the cost. It is expensive."
"There is a good solution from Microsoft, however, there is a gap between Windows and Linux management."
"The worst aspect is the refresh rate of the dashboard."
"The setup phase of the product is not that easy and needs a person to have a certain level of expertise."
"The automated remediations can be more specific."
