Crowdsourced security has strengthened our bug discovery and improved vulnerability response

HackerOne is already doing well, although I believe implementing stricter SLAs for the time to first response and time to bounty would help prevent researchers' burnout, especially regarding duplicate submissions. I suggest systematic bug rewards because currently, if a researcher finds one bug in multiple places, they often only get paid for one. Improving the handling of systemic vulnerabilities would encourage deeper research. Additionally, improving multi-currency and crypto payout options would help make the platform more accessible globally.

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."

"HackerOne has been the right fit for our current situation from both a functionality and cost-effectiveness perspective."

"HackerOne is larger than WebCloud and has a better reputation than BugCloud, which results in a smoother process."

"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."

"If you are starting out as a beginner in penetration testing and want to become a professional in bug bounty, I would advise you to get started with HackerOne."

"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."

"Using HackerOne has definitely improved the security of my web application, identifying security gaps I didn't realize as a web developer."

More HackerOne pros

"The ImmuniWeb Platform is the best and easiest way to secure a business online."

"ImmuniWeb boasts a robust vulnerability detection mechanism, formidable threat mitigation, and an efficient remediation process, incorporating automation techniques and ALM strategies. The solution is highly stable. The solution is scalable. Editing Key Points for Review "Review about ImmuniWeb" What is our primary use case? We use the solution when we face challenges and urgent attention is needed for complex cases from our clients. To address this, we collaborate with the middleware, internal, and client teams to analyze and sort through intricate logs concerning our business cybersecurity program. How has it helped my organization? The solution helped us with one of our clients in the New York area contacted us about a data breach. In response, we swiftly organized a case meeting involving our client, internal, and email customer support teams. Together, we conducted an incident response, facilitating offline assistance for proper planning and risk management processes. We delved into the details of the data breach, identified how it occurred, and collaborated to rectify the issue. The client expressed satisfaction with the resolution process. What is most valuable? ImmuniWeb boasts a robust vulnerability detection mechanism, formidable threat mitigation, and an efficient remediation process, incorporating automation techniques and ALM strategies. It also focuses on consumer satisfaction and operates in English-speaking markets, primarily required by the UAE, the United States, Canada, and Australia, among other developed countries. For how long have I used the solution? We have been using this product for the past one and half years. What do I think about the stability of the solution? The solution is highly stable. I rate it a perfect ten. What do I think about the scalability of the solution? The solution is scalable. I rate it a nine out of ten. How are customer service and support? Support is generally excellent"

"ImmuniWeb is stable."

"After the assessment, you clearly know which assets require penetration testing."

"The initial setup process is user-friendly."

"The most valuable features are the SLA of Zero false-positives, less time of service development, validation of unlimited patched vulnerabilities, and several others."

"I like the fully automated continuous discovery run by ImmuniWeb in the background. We do not need to rerun the same tests or the same scanning against our resources. We need to supply our IP addresses, domain names, and significant resources with special domain names and URLs, and we need to do it only once. Then we always have an up-to-date picture. I also like the integration with our single sign-on system. We do not need to maintain a separate set of usernames or user accounts. We can plug this ImmuniWeb service into our authentication technology, enabling two-factor authentication. We have secure authentication right out of the box. The other important feature I like is the executive view. You can easily switch from a technical view to an executive view and have a helicopter view of the compliance status. We can see how much effort is required and our current status."

"The solution's most valuable feature is reporting."

More ImmuniWeb pros

Cons

"Everything has become slower on HackerOne."

"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."

"The ability to view the conversation between the triagers and the programs will be really good."

"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."

"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."

"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."

"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."

"Everything has become slower on HackerOne. I have noticed that older researchers receive all the private invites while newer ones receive fewer."

More HackerOne cons

"It would be better if they had an automated tagging feature. The tagging functionality currently requires manual tagging, and that's probably the most needed feature from my standpoint. We also do not have enough tools, enough features, or options to display different resources in the way we need. There are basic grouping and some filtering features, but we still cannot fully separate some flavors of our resources. However, we may not be aware of the latest features."

"The product’s interface for the web applications could be similar to Android and iOS versions."

"ImmuniWeb sometimes shows previous scans instead of running tests."

"You may find the dashboard a bit complicated."

"The deployment process on the cloud is straightforward, while on-premise can be complex. Support is generally excellent, although there can be delays in ticket resolution."

"Its technical support could be better."

"A great idea would be to support using Discovery on the internal network, allowing delivery of all the features of the current Discovery to internal network resources."

"A great idea would be to make a mobile application for the ImmuniWeb portal so that all information would be available on the go and from a mobile phone as well. It would be much more convenient."

More ImmuniWeb cons

Pricing and Cost Advice

"The solution is free."

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

"It is pretty expensive."

"I use the product's free version. The tool costs around 229 dollars."

"The values of ImmuniWeb are currently significantly below what is valued in the Chilean market for these services and solutions."

"There should be the flexibility to change or add pricing, especially for pay-per-use cases."

"ImmuniWeb is relatively cheap. It's a competitive price compared to other products in the marketplace. It's worth the money we are paying for it."

"It is pretty expensive."

"The platform is expensive if a large development is involved. However, it is less expensive for scheduled-based testing, quarterly or in a year."
