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.

Offers robust compliance features but needs improved automation in remediation
The automation capability remediation needs improvement. The current process requires manually telling IT teams to remediate vulnerabilities, and then they update the status of these vulnerabilities in the platform. This basic feature that Rapid7 calls an automated remediation process is actually manual. We can update the status of vulnerabilities in the Rapid7 InsightVM platform and collectively see how many vulnerabilities we have identified and how many are remediated by our IT team. More automation in the remediation feature is a basic demand from many customers. The remediation part and vulnerability identification of network devices or rigid devices are not currently supported by Rapid7 InsightVM. More integration and automation are the two areas Rapid7 needs to improve in their product.

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

"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."
"Zafran is an excellent tool."
"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 has become an indispensable tool in our cybersecurity arsenal."
"InsightVM has a very organized GUI with ease of use."
"The solution scales well."
"The product's initial setup phase was very easy."
"The solution's user interface is good and has some vulnerability prioritization."
"The most valuable feature for me is the risk calculation based on monthly effects."
"Customers are generally satisfied and do not ask for drastic price reductions during renewals."
"The cost is what is most valuable. Compared to the other products on the market, the cost is more palatable."
"NeXpose is a pretty good vulnerability scanner... There's a nice dashboard."
"Once you get past the initial implementation, the solution is very stable."
"Vulnerability assessment is the most valuable feature in Tenable Nessus, as it provides brief details regarding the vulnerability issues we have in our network."
"I have found the vulnerability assessment and the reports to be useful."
"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
"It is a mature tool."
"Tenable Nessus has provided increased visibility across the organization's servers."
"Out of the box, the product works well for us, so it's not a tool that we need to customize very much."
"Tenable Nessus is an absolutely stable and fantastic product."
 

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."
"There should be containerization within the VM."
"There are end-user needs and expectations that are being overlooked in the development that could be addressed by appointing a customer advisory board."
"The InsightVM cannot scan if we connect to our customer by the VPN."
"In order to be able to properly test the solution and make a decision, I would like to receive the test license code instantly and eliminate the wait time."
"It would be great to have a mobile application client. Currently, you have to use a mobile web browser on a device, but it is not similar to the desktop web browser in terms of user experience. It would be nice to have a mobile application to access the platform."
"Their customer support should be improved, and the effectiveness of scans also needs to be improved."
"There is a significant learning curve, that non-technical individuals, especially those not specialized in computer science or the information security industry, might face."
"I would like to see more integration."
"The solution should be able to support more devices."
"The most that Tenable Nessus could improve is its speed because they might have put a lot of effort into compatibility issues that downgrade the speed."
"The product could have unique features similar to one of its competitors."
"The inventory management function in this solution needs improvement."
"The price could be reduced."
"In terms of what could be improved, I would say its reporting portion."
"The solution could improve security updates."
"Tenable Nessus could include a broader range of IT assets."
 

Pricing and Cost Advice

Information not available
"Our licensing costs are somewhere around $40,000 annually. There are no additional fees."
"The price of the solution is less than the competitors."
"Licensing fees are paid on a yearly basis."
"It is pretty expensive. It depends on what you consider pricey, however, if you only look at vulnerability management solutions, such as within VM or VMDR, there are, I suppose the prices are almost the same. But I believe you will discover that for yourself."
"The license is IP based. How many IPs you are using to scan is the amount of the license you have to buy. The number of users doesn't matter; many users can use it or only person. It depends on the culture of the organization."
"Pricing is reasonable because we pay according to asset usage. We can define our assets and sites according to our preference."
"The solution's pricing is better than Nexus which charges a high amount for very little use."
"We purchase annual licenses."
"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"Tenable Nessus is affordable."
"The price is reasonable."
"Nowadays, your vulnerability applications are going to be kind of pricey because lots of them, including Rapid7, are based upon a base price, but then they add in the nodes. That's where they get you. If you're a big network, obviously, you need to scan everything. Therefore, it's going to be costly. The risk and insurance money associated with having ransomware on my networks is going to cost me more money, time, and marketing than the price of the tool. That's why I'm speaking only as an information security officer to security operations. This is the tool that is there in my toolbox to say whether we vulnerable or not. At this point, I don't care about how much it costs my company to have it because if I wasn't able to report it and we got ransomware, then who cares? I'm probably going to be out of business because it happened. That's why I don't care about the price. I have it, and I could use it effectively and do my report. At the end of the day, even if we get ransomware, as long as I reported it, followed my protocol, and put in the change, irrespective of whether it was ignored or denied, I did my job."
"I would like to see better discounts."
"The solution has free options."
"The solution is expensive."
"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."

InsightVM - better functions on granting users different access to different asset groups.  It fits better for our company and is slightly cheaper.

You have full visibility across cloud, network, virtual, and containerized infrastructures with Rapid7 Insight VM. You can easily prioritize vulnerabilities using attacker analytics. Overall, Rapid7 Insight VM is easy to understand, use, and deploy. This solution supplies many different types of valuable reporting and rarely reports false positives. Rapid7 can easily detect new devices and scan endpoints quickly for vulnerabilities, misconfigurations, or missing patches. Rapid7 Insight VM will identify the risk and suggest how to resolve the problem. We would like to see the reporting improved to offer some of the options other solutions provide. Rapid7 Insight VM can be a very expensive solution - it is really only for larger enterprise accounts. Integration with other solutions would make Rapid7 Insight VM more desirable. It’s easy to combine local testing with network-based testing using Tenable Nessus, which can easily find vulnerabilities across different platforms and operating systems. Tenable Nessus will identify what nodes you have in place, then provide you with a report identifying each vulnerability found by node. It works quickly and stealthily, and offers clear-cut reporting and the ability to scan for specific vulnerabilities. We would like to see the reporting process with Tenable Nessus improved. Instead of only PDF reports, one option might be to track with an Excel-based structure to better track vulnerabilities and remediation efforts and build reports from there. An option to use the same license for the cloud and on-premises at the same time would be very useful. Conclusion We felt that Tenable Nessus provided better reporting of vulnerabilities per device in a clearer, easier to understand manner. It is a very easy solution to use and makes accountability for tracing and reporting vulnerabilities easy. The flexible scanning options offered by Tenable Nessus are what we found most advantageous.
