Senior ICT Security Consultant at Applied Principles Limited
Has improved my motivation to submit bugs consistently through fast response and clear filtering
I think HackerOne can be improved by allowing new users to gain access to certain programs that are only open to known, renowned users. Sometimes new users don't receive invites just because they are new, despite potentially being very skilled hackers, so I feel new users should get more chances and opportunities. I am currently satisfied with the rewards, response time, and other aspects of the platform, so I don't have anything else to add about the necessary improvements. I give HackerOne a nine out of ten because if new hackers are given more opportunities, it could be a perfect 10 for me. However, the reason I gave a nine is that I don't have much to complain about; I specifically love the program and don't have many concerns.

Microsoft Solutions Manager at Self-Employed
Ensures strong threat and vulnerability management with continuous risk assessment
The major priority is identity, which is crucial; we have lots of companies in manufacturing, energy, or various sectors, and it varies from one to another. I assess Microsoft Defender Vulnerability Management as very effective in continuously assessing vulnerabilities without requiring scans. We use automatic investigation and remediation features, safe attachments, safe links, and real-time reports, which are also very effective. For Active Directory, Defender has threat intelligence, and we are using that. The risk-based prioritization within Vulnerability Management affects my ability to manage vulnerabilities, particularly in relation to the Zero Trust Model utilized by our customers. The end-users often do as they please in their systems.

Quotes from Members

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

Pros

"If you have a very critical vulnerability, some good companies will acknowledge it and pay you accordingly based on severity."
"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 fast verification process impacts my motivation significantly because a quick response keeps me motivated, and if I'm going to try and hunt bugs today, I would appreciate a response within the day or at least within a few days."
"HackerOne is larger than WebCloud and has a better reputation than BugCloud, which results in a smoother process."
"The most valuable feature of HackerOne is its variety of programs. These programs provide depth into various areas, such as mobile, API, and websites."
"HackerOne is a very good platform with the trust of different companies including Shopify, PayPal, and Uber, which creates a stronger brand perception and competitive market positioning."
"HackerOne has been the right fit for our current situation from both a functionality and cost-effectiveness perspective."
"It helps me to get new sales, profits, and other benefits."
"The integration with Sentinel has been one of the most valuable features for my organization."
"A valuable feature is the ease of management and integration with Microsoft products."
"Microsoft Defender Vulnerability Management is a good product, and I believe it deserves a positive recommendation."
"The integration with Sentinel has been one of the most valuable features for my organization."
"The most valuable aspect is the kind of assessment results I get, and the recommendations provided in Microsoft products really help in taking care of the resources."
"The integration with SIEM is the best, specifically the native integration with Microsoft SIEM."
"One valuable feature is the Microsoft Security Scorecard."
"The solution helps identify threats and vulnerabilities."
 

Cons

"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."
"One limitation is that if a finding has been reported on HackerOne and was also reported earlier by another user or outsider, the platform is not able to collate that information together."
"However, I reduced my rating by one mark because a proper internal triage team should be in place, not as a replacement for internal security controls."
"Everything has become slower on HackerOne."
"Triage response time is a significant issue. The response time and triage speed are not fast enough, and this is causing many people to leave HackerOne."
"Sometimes new users don't receive invites just because they are new, despite potentially being very skilled hackers, so I feel new users should get more chances and opportunities."
"HackerOne provides a "HackBot" which helps identify other relevant reports, including duplicates, public reports from other companies, etc. However, the functionality is limited and it would be nice to integrate it with broader services offered like auto responses, triggers, etc."
"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 product is not stable; it is very resource-intensive, consuming a lot of memory and CPU, which makes it slow."
"The worst aspect is the refresh rate of the dashboard."
"There should be risk scoring added to Microsoft Defender Vulnerability Management; specifically, they call it quantification of the risk."
"When I create rules, it gave me problems and I did not know where the problem was located."
"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."
"It is expensive."
"The general support could be improved."
 

Pricing and Cost Advice

"The tool is open-source and free for bug bounty hunters."
"The solution is free."
"I rate the product's price a three on a scale of one to ten, where one is a low price, and ten is a high price."
"The licensing costs are reasonable."
"The licensing model follows a per-user per-month structure."
"The tool is a bit costly."
"The product’s pricing is medium."
