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.

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.

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

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."
"Zafran is an excellent tool."
"We saw benefits from Zafran Security almost immediately after deploying it."
"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 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."
"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."
"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."
"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 plug-in text information is quite useful."
"The best features of Tenable Nessus include its compatibility with other applications such as SIEM and other apps, allowing Tenable Nessus to work smoothly with them."
"The most valuable feature of Tenable Nessus is the GUI and user-friendliness. Additionally, the environment is easy to work with."
"Nessus is effortless to integrate."
"We looked at Tenable, Qualys and Rapid7. We found Tenable was the best of all three."
"The most valuable feature of Tenable Nessus is real-time monitoring."
"It does exactly what you expect it to do, and its pricing is great. We couldn't really ask for a better deal."
"I am impressed with the tool's vulnerability scanning."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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."
"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."
"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."
"Everything has become slower on HackerOne."
"The ability to view the conversation between the triagers and the programs will be really good."
"The price could be reduced."
"Technically, it is an excellent and the best solution available in Libya. My only concern is related to its pricing. They are an emerging company in Libya, and they need to put in some effort to provide us with very good prices so that customers can go with the best solution. Chinese companies are getting into the market here, and they're providing very cheap solutions."
"Tenable Nessus application device assessment is one of the top tools. However, in the application security assessment, there are other tools that provide better, and more accurate findings."
"We'd like to see the solution embrace more user-friendliness."
"There should be a possibility to install agents on scanned machines. Tenable IO provides the capability of using local agents to check local problems, but this feature is not there in Tenable Nessus Professional. It would be nice to have something similar in Tenable Nessus Professional. We should have the capability to use local agents installed on the machines to locally check a problem."
"It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features."
"The interface is a little bit clunky, and the reporting is not marvelous. There should be better integration of reporting between instances. Currently, the instance stands alone, and it produces a report. Being able to amalgamate those reports with another instance will be useful."
"They have added a new Tenable Nessus Expert. That is their new product, which caters to the cloud and everything else. I am assuming that the new features and product enhancements are based on that tool set, but we haven't reviewed it yet."
