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.
César Ibáñez - PeerSpot reviewer
A highly scalable and easy-to-use solution that helps identify vulnerabilities
The time taken for a scan is too long. I tried to scan a website, and it took me ten hours. The report was sent to me two days later. The reports must be more specific to help us understand what we should do to mitigate the problem. There is not a lot of documentation on how to manage all the features of the product.
MohammedJaffir - PeerSpot reviewer
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 is an excellent tool."
"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."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"The solution is very easy to use."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
"The support has been really cooperative."
"Tenable Nessus has a good performance, is very user-friendly, and is easy to use."
"Nessus gives me a good preview of vulnerabilities and good suggestions for remediation. It's easy to find a description of a given vulnerability and solutions for it."
"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
"The most valuable feature is the installation of Tenable which is incredibly easy."
"Tenable Nessus has provided increased visibility across the organization's servers."
"The reports are pretty nice and easy to understand."
 

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."
"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."
"The reports must be more specific to help us understand what we should do to mitigate the problem."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"Remediation needs improvement."
"Vulnerability recommendations are outdated and not in line with industry standards."
"Tenable Nessus could improve the reporting by adding some dashboards. The reports are a hassle at this time. Tenable.io has more detailed reports. Having a better dashboard that can show where the vulnerabilities are and be categorized would be helpful. We then could present them to upper management for a deep overview of our network posture which they do not see."
"The pricing point has increased significantly in recent years. The product's pricing has roughly tripled within the last couple of years, making us reconsider renewing the license for the scanner."
"The product could have unique features similar to one of its competitors."
"The price could be reduced."
"Tenable Nessus is very costly compared to OpenVAS and sits on the higher side."
 

Pricing and Cost Advice

Information not available
"The product is free."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"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 price of Tenable Nessus is much more competitive versus other solutions on the market."
"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."
"The cost is around $4,300 per year. Use is unlimited. You don't pay more if you want to use it for another IP."
"The price of Tenable Nessus is too expensive for each service center."
"The is a free version of Tenable Nessus available."
"The price of Tenable Nessus could improve, it is expensive."
