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."
"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."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"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."
"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 most valuable feature of HackerOne is its variety of programs. These programs provide depth into various areas, such as mobile, API, and websites."
"It helps me to get new sales, profits, and other benefits."
"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."
"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."
"The support has been really cooperative."
"The most valuable aspect of this solution is that you receive the entire report, which details the breakdown, especially in terms of critical, high, low, and mediums."
"Tenable integrates well with other solutions such as SIEM and batch management."
"The vulnerability scanner is the most valuable feature."
"The most valuable feature is the breadth of vulnerabilities that it finds. It's able to find across a lot of different platforms and operating systems. It's also able to combine local testing with network-based testing."
"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."
"It is easy to deploy and easy to use. Its reporting is good. From this reporting, you can see the pain point in your network, which makes it easy to fix them. It is easy to understand the reports and export them."
"A valuable feature of the solution is that it is easy to understand."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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."
"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."
"Everything has become slower on HackerOne."
"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."
"The ability to view the conversation between the triagers and the programs will be really good."
"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."
"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."
"The price could be more reasonable. I used the free Nessus version in my lab with which you can only scan 16 IP addresses. If I wanted to put it in the lab in my network at work, and I'm doing a test project that has over 30 nodes in it, I can't use the free version of Nessus to scan it because there are only 16 IP addresses. I can't get an accurate scan. The biggest thing with all the cybersecurity tools out there nowadays, especially in 2020, is that there's a rush to get a lot of skilled cybersecurity analysts out there. Some of these companies need to realize that a lot of us are working from home and doing proof of concepts, and some of them don't even offer trials, or you get a trial and it is only 16 IP addresses. I can't really do anything with it past 16. I'm either guessing or I'm doing double work to do my scans. Let's say there was a license for 50 users or 50 IP addresses. I would spend about 200 bucks for that license to accomplish my job. This is the biggest complaint I have as of right now with all cybersecurity tools, including Rapid7, out there, especially if I'm in a company that is trying to build its cybersecurity program. How am I going to tell my boss, who has no real budget of what he needs to build his cybersecurity program, to go spend over $100,000 for a tool he has never seen, whereas, it would pack the punch if I could say, "Let me spend 200 bucks for a 50 user IP address license of this product, do a proof of concept to scan 50 nodes, and provide the reason for why we need it." I've been a director, and now I'm an ISO. When I was a director, I had a budget for an IT department, so I know how budgets work. As an ISO, the only thing that's missing from my C-level is I don't have to deal with employees and budgets, but I have everything else. It's hard for me to build the program and say, "Hey, I need these tools." If I can't get a trial, I would scratch that off the list and find something else. I'm trying to set up Tenable.io to do external PCI scans. The documentation says to put in your IP addresses or your external IP addresses. However, if the IP address is not routable, then it says that you have to use an internal agent to scan. This means that you set up a Nessus agent internally and scan, which makes sense. However, it doesn't work because when you use the plugin and tell it that it is a PCI external, it says, "You cannot use an internal agent to scan external." The documentation needs to be a little bit more clear about that. It needs to say if you're using the PCI external plugin, all IP addresses must be external and routable. It should tell the person who's setting it up, "Wait a minute. If you have an MPLS network and you're in a multi-tenant environment and the people who hold the network schema only provide you with the IP addresses just for your tenant, then you are not going to know what the actual true IP address that Tenable needs to do a PCI scan." I've been working on Tenable.io to set up PCI scans for the last ten days. I have been going back and forth to the network thinking I need this or that only to find out that I'm teaching their team, "Hey, you know what, guys? I need you to look past your MPLS network. I need you to go to the edge's edge. Here's who you need to ask to give me the whitelist to allow here." I had the blurb that says the plugin for external PCI must be reachable, and you cannot use an internal agent. I could have cut a few days because I thought I had it, but then when I ran it, it said that you can't run it this way. I wasted a few hours in a day. In terms of new features, it doesn't require new features. It is a tool that has been out there for years. It is used in the cybersecurity community. It has got the CV database in it, and there are other plugins that you could pass through. It has got APIs you can attach to it. They can just improve the database and continue adding to the database and the plugins to make sure those don't have false positives. If you're a restaurant and you focus on fried chicken, you have no business doing hamburgers."
"Tenable Nessus could improve the reporting."
"From my point of view the solution basically is not for the big enterprise."
"Scans aren't done properly and some devices aren't pinged."
"We'd like to see more integration potential within the solution."
"Some things in the user interface could be better. The user interface could allow more adjustments to plugins. The price could also be better."
"I would like to see an improvement in the ranking of high, medium and low vulnerability."
"The reporting feature needs to be improved."
