Has become an indispensable tool in our cybersecurity arsenal
While Zafran Security is already a powerful tool, there are areas where it could be further improved to provide even greater value. One key area for enhancement is the searching capabilities within its vulnerabilities module. By incorporating the ability to create Boolean searches, users would gain the ability to apply more complex filters and customize their search criteria. This would greatly enhance the precision and efficiency with which security teams can identify and prioritize vulnerabilities. Having such tailored search capabilities would save time and resources by narrowing down vast lists of vulnerabilities to those that meet specific parameters relevant to our unique risk environment. Additionally, integrating more robust reporting and visualization tools would be advantageous. Enhanced dashboards that offer customizable visual representations of risk configurations and threat landscapes would facilitate better communication with stakeholders, making it easier to explain vulnerabilities and the rationale behind certain security measures. This would also aid in demonstrating the improvements and value derived from existing security investments to leadership and non-technical team members.

Provides early detection of imminent attacks, and speeds up addressing of vulnerabilities internally because it makes them real
They're a newer company, so they're working on their UI a lot. Sometimes the UI is a little glitchy. They're working on different things and making efforts, so that's totally forgivable. But regarding their scraping abilities, things could be solidified. There are definitely improvements that could be made on the specificity for setting certain queries. Step-by-step videos would be useful, instead of a book of instructions, because they're a new tool. They're now getting to the point where video training would be useful, or even live training. More digestible video instructions or opportunities for training, so that you actually learn hands-on, would help.

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.

Quotes from Members

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

Pros

"Zafran has become an indispensable tool in our cybersecurity arsenal."
"With Zafran Security, it integrates with your security controls, allowing you to take that risk score and reduce it based on the controls in place or increase the risk based on different factors, such as if the issue is internet reachable or if there's an exploit in the wild."
"We saw benefits from Zafran Security almost immediately after deploying it."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"Zafran is an excellent tool."
"The solution’s approach of using limited open source intelligence and focusing, instead, on the Deep Web and Dark Web is what seals the deal. That is why I like them. I have other tools that I can aggregate all the open source intelligence from. I value Cybersixgill because it provides access to things that no one else does."
"To be diligent for the customer, we usually go into Cybersixgill Investigative Portal to analyze and search things. The solution tells us the reputation of cyber threat actors. So, if someone has a reputation of one, it is a really bad idea to care about what that person is saying. However, if you find someone with a reputation of nine, then there is a high probability that we need to address the problem. You can get information about these type of actors in Cybersixgill Investigative Portal. They have a huge collection, which is like having the rules/goals of the dark web and deep web without having to go there. Our analysts avoid going dark web because they have Cybersixgill Investigative Portal and can get the news from their browser, searching wherever they want."
"The advanced analysis has made our security operations more efficient. It has also potentially given us quicker access to data that we might not have otherwise located."
"They also provide some of the greatest notification capabilities. I put in a customer's company name and domain names, or sometimes I put in their IP addresses as a keyword. Once Sixgill collects information that includes those keywords, they then provide us email notifications. That means we can catch information related to our customers as soon as possible."
"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."
"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."
"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."
 

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."
"The breadth of access to data is good, but there are gaps. More data would be my suggestion because the platform is good and I have no complaints about the system. I think it is just a case of always trying to get more data sources."
"Regarding their scraping abilities, things could be solidified. There are definitely improvements that could be made on the specificity for setting certain queries."
"We need real-time updated information. If we could have this, it would be amazing. For example, if someone was posting something, then ten second later, it was on the platform. Sometimes, it takes a minute or hours right now, depending on the forum."
"Sixgill has strong capabilities based on search queries, but there is some difficulty in using Sixgill. Their querying is very powerful but it can be difficult. It's not hugely complex but you need some skill to use Sixgill querying."
"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."
"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."
"Everything has become slower on HackerOne."
"The ability to view the conversation between the triagers and the programs will be really good."
 

Pricing and Cost Advice

Information not available
"The pricing is cheap compared with Recorded Future. Sixgill's cost-effectiveness is very good."
"Sometimes, Cybersixgill Investigative Portal is cheaper than its competitors."
"The pricing and licensing are good. It is expensive for us because the US dollar is quite strong compared to our dollar. Otherwise, it is quite reasonable for what it is. All the tools in the market are around the same price from my experience."
"The tool is open-source and free for bug bounty hunters."
"The solution is free."
