Featured Reviews

Israel Cavazos Landini - PeerSpot reviewer
Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.
Mahmoud Elhamaymy - PeerSpot reviewer
Reliable scanning and integration strengthen security infrastructure
InsightVM has a very organized GUI with ease of use. The vulnerability scans are reliable, and the credential scan is a beneficial feature. The solution is efficient and trustworthy. It's based on the CVSS risk scoring system, which is well-recognized and effective. The integration capabilities through APIs allow easy integration with existing security infrastructure.
HarshBhardiya - PeerSpot reviewer
Provided increased visibility across the organization's servers
The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.

Quotes from Members

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

Pros

"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Zafran is an excellent tool."
"The most valuable feature is the site scanning, where we can provide a complete subnet and what it is we need to scan on those devices."
"The product is scalable."
"The solution scales well."
"Has great reporting features."
"We are very satisfied with the reports, as they provide us with the information that is required for our management."
"The solution is automatically scheduled so it runs by itself."
"We can create our own templates."
"The most valuable feature for us is the different types of reporting it provides."
"The solution is the most dynamic one I have seen thus far."
"The initial setup is very straightforward."
"Nessus' most valuable feature is vulnerability management because it helps to discover vulnerabilities proactively and integrates with patch management solutions so you can push patches."
"The scanning and reporting features are the most valuable aspects of Tenable Nessus."
"Its initial setup was simple and straightforward."
"Tenable Nessus is an absolutely stable and fantastic product."
"Among the most valuable features are scanning for vulnerabilities and the reporting. The reporting templates are okay. I like that I can see all the hosts with different vulnerabilities."
"Nessus is effortless to integrate."
 

Cons

"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."
"Customer service needs significant improvement. There are delays in support response times, and support is not available promptly, especially when issues are escalated to another region."
"Rapid7 InsightVM could be easier to use for those who are using it for the first time."
"There have been instances where technical support takes a long time to update the status of a ticket, which is something that can be improved."
"The product's documentation could be enhanced with clearer and more detailed instructions."
"Rapid7 could be easier to manage."
"They should improve the cybersecurity feature of the solution."
"The platform could be more intuitive and user-friendly."
"The authentication scan is not working."
"To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat. For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved."
"I would like to have a management option after the network scanning."
"EQA's and dashboards should be addressed in the next release."
"We have had some false positives in the past, which we hope can improve in the future."
"Scans aren't done properly and some devices aren't pinged."
"Vulnerability recommendations are outdated and not in line with industry standards."
"Consumes more system resources when it's running."
"There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."
 

Pricing and Cost Advice

Information not available
"The licensing is asset-based and very straightforward."
"A full license for the solution is expensive because it is at the organizational level and not by individual users."
"This solution is expensive, but it's fine for us as we have an open budget for security solutions. Protection and having the system secured is more important."
"It is less expensive compared to other competitors."
"Comparing the price with the value that we receive, I am not happy with it."
"The license is annual and this is the optimal approach when it comes to most software."
"The solution's pricing is better than Nexus which charges a high amount for very little use."
"Its licensing is yearly. Everything is included in the price for one year."
"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."
"The solution has a single price for unlimited assets."
"The price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
"Tenable Nessus needs to be licensed. We own a license for the security center and that license is charged by the number of IP addresses that you can scan. You're allowed to have as many scanners as you want and there's no license for the number of scanners. We have a bunch of Nessus scanners out there, and as long as we're comfortable with staying under that IP address limit, that's really all we have to be concerned about."
"We pay approximately $2,500 on a yearly basis."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"I would like to see better discounts."

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.
