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.

Lets you find defects during the development phase, so you don't have to wait till the development is over to find and address flaws

What needs improvement in Klocwork, compared to other products in the market, is the dashboard or reporting mechanisms that need to be a bit more flexible. The Klocwork dashboard could be improved. Though it's good, it's not as good as some of the other products in the market, which is a problem. The reporting could be more detailed and easier to sort out because sorting in Klocwork could be a bit more time-consuming, mainly when sorting defects based on filters, compared to how it's done on other tools such as Coverity. What I'd like added in the next release of Klocwork is the peer code review Cahoots which used to be a part of Klocwork, and the architecture analysis and both have been taken out of Klocwork. I found the two critical for specific deployments, so if those can be brought back to Klocwork, that would be very good.

Quotes from Members

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

Pros

"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."

"It helps me to get new sales, profits, and other benefits."

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

"We like using the static analysis and code refactoring, which are very valuable because of our requirements to meet safety critical levels and reliability."

"On-the-fly analysis and incremental analysis are the best parts of Klocwork. Currently, we are using both of these features very effectively."

"Klocwork is user-friendly, with a client-server architecture that provides all needed compliance."

"Klocwork's most valuable feature is the static code analysis feature. It detects the potential problem earlier to allow the developer to receive feedback quickly and then address it before it becomes a problem."

"The most valuable feature of Klocwork is its reduced setup time."

"There's a feature in Klocwork called 'on-the-fly analysis', which helps developers to find and fix the defects at the time of development itself."

"The most valuable feature of Klocwork is finding defects while you're doing the coding. For example, if you have an IDE plug-in of Klocwork on Visual Studio or Eclipse, you can find the faults; similar to using spell check on Word, you can find out defects during the development phase, which means that you don't have to wait till the development is over to find the flaws and address the deficiencies. I also find language support in Klocwork good because it used to support only C, C++, C#, and Java, but now, it also supports Java scripts and Python."

"The customer support team is very responsive, proactive, and engages in conversations to ensure our needs are met."

More Klocwork pros

Cons

"Everything has become slower on HackerOne."

"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."

"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."

"What needs improvement in Klocwork, compared to other products in the market, is the dashboard or reporting mechanisms that need to be a bit more flexible. The Klocwork dashboard could be improved. Though it's good, it's not as good as some of the other products in the market, which is a problem. The reporting could be more detailed and easier to sort out because sorting in Klocwork could be a bit more time-consuming, mainly when sorting defects based on filters, compared to how it's done on other tools such as Coverity."

"There are too many warnings, and it requires expertise to determine the correct category for them."

"The way to define the rules is too complex. The definition/rules for static analysis could be automated according to various SILs, so as to avoid confusion."

"Klocwork does have a problem with true positives. It only found 30% of true positives in the Juliet test case."

"We'd like to see integration with Agile DevOps and Agile methodologies."

"There are too many warnings, and it requires expertise to determine the correct category for them."

"We bought Klocwork, but it was limited to one little program, but the program is now sort of failing. So, we have a license for usage on a program that is sort of failing, and we really can't use the license on anything else."

"I hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."

Pricing and Cost Advice

"The solution is free."

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

"Klocwork is still tight on their licensing. If Klocwork would loosen up on the licensing, and where the license could be used, and how many different programs could be run on it, then we have several development programs that I would love to be able to use it for going forward."

"The limitation that we have is that Klocwork is licensed to certain programs, and if you want to license them to other programs, you have to pay more money."

"Licensing fees are paid annually, but they also have a perpetual license."

"The pricing for Klocwork is very competitive if you compare it from apple to apple. It has competitive pricing regarding the licensing model and the per-license cost. Klocwork isn't a high-end investment for anyone deploying it; even SMBs can afford it. The Klocwork cost per user would depend on the license type, so I'm unable to mention a ballpark figure because it would depend on the type of installation and how the deployment will be, and the nodes to give an accurate calculation or figure. The total price depends on the package, so my company could never publish pricing for Klocwork on the website. My team first collects information from potential clients on the deployment scenario, project environment, etc., before suggesting a package for Klocwork. My rating for Klocwork in terms of pricing is a five because of its flexible license models. There's a license model for every type of organization, whether small, midsize, or enterprise, so it's a five out of five for me."

"Klocwork should not to be quite so heavy handed on the licensing for very specific programs."

"There are other solutions on the market such as Microsoft Visual Studio. They have been adding more static code analysis features that come for free. It is getting better all the time. That is one of the possibilities is that we've been considering that we may stop using the Klocwork because it doesn't give us any added value."

"When it comes to licensing, the solution has two packages, one for a fixed and the other for a floating server, with the former being more cost effective than the latter."

"This solution offers competitive pricing."
