Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

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.

Health Care Specialist at a healthcare company with 11-50 employees
Improved radiation safety and compliance has supported patient care but daily workflows still need refinement
I think it can be improved by making it more practical, integrated, and easier for teams to apply in real-world workflow from a healthcare perspective. The main improvements I can see right now are better user training with real-case scenarios rather than only theory, and clear and simple protocols for day-to-day operations. Strong integration between safety compliance and documentation systems would help significantly in practice for the healthcare field, which is a niche field. The biggest gain would come from making security processes easier to follow consistently, especially in busy environments where teams need to be aware of clarity and really need to rely on the documentation they are using.I chose a rating of seven because it offers strong value in safety, risk reduction, and compliance, especially in healthcare. However, there is still room for improvement in usability and day-to-day integration. Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow.

Quotes from Members

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

Pros

"I appreciate TotalCloud's real-time protection and remediation features. The remediation options include automated one-click remedies and custom changes that help manage vulnerabilities efficiently."
"The scalability is good as well. I would rate it ten out of ten."
"Vulnerability and threat detection and assessment of the criticality of the vulnerabilities exposed are most valuable."
"The most valuable feature is extensibility."
"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."
"I would definitely recommend it because it is easy to handle any cloud resources."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"Qualys TotalCloud provides a single, prioritized view based on requirements such as identifying the most vulnerable assets and calculating the average time to remediate vulnerabilities."
"I notice a return on investment through the group of researchers at HackerOne identifying vulnerabilities, saving us money, time, and manpower, with the efficiency of HackerOne allowing them to accomplish in three to four hours what would take two red teamers a whole day."
"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."
"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."
"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."
"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 has been the right fit for our current situation from both a functionality and cost-effectiveness perspective."
"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."
 

Cons

"It is already perfect, but they can bring some newer dashboards and customization options for the dashboard. It would be great to be able to include on-prem assets on the dashboard."
"The cost of Qualys TotalCloud is high and could be more competitive."
"The patching process with Qualys Patch Management, which is part of TotalCloud, does not cover installing certain prerequisites on the servers or workstations. This shortcoming means we must rely on SCCM when any service stack updates or additional prerequisites are needed."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"The support is not up to the mark and seems to be overburdened."
"TotalCloud could improve the classification of vulnerabilities. Specifically, it could enhance the categorization of what aspects fall under patches resolved by OS or software updates and what pertains to configuration adjustments."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"Qualys's ticketing system can be confusing when assigning tasks to individuals, and support could be improved by offering instant call solutions with engineers in addition to ticket replies."
"Everything has become slower on HackerOne."
"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."
"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."
"Everything has become slower on HackerOne. I have noticed that older researchers receive all the private invites while newer ones receive fewer."
"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."
"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."
"Customer support can improve, as there are instances of ghosting that need to be addressed."
"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
 

Pricing and Cost Advice

"Qualys TotalCloud offers cost-effective licensing flexibility."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"The cost is high, but it meets our organizational needs."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"Qualys TotalCloud is expensive."
"The tool is open-source and free for bug bounty hunters."
"The solution is free."
