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.
Ankesh Raj - PeerSpot reviewer
Real-time responses and reporting streamline vulnerability management
Qualys VMDR provides a real-time response and reporting feature, which is excellent. It allows us to see real-time graphs and reports for every asset, server, and more, which is very user-friendly. Our clients have given good feedback, and they are satisfied with the tool. We use it daily to fix vulnerabilities by connecting with infrastructure to remediate. The feedback from the client side is very good.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Zafran is an excellent tool."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"I am impressed with the VMDR feature."
"Technical support is fantastic."
"Monitors workstations and servers for vulnerabilities and creates reports."
"The product's patch management is excellent for keeping our critical servers and third-party applications updated efficiently."
"It's a good product. After the scan our internet works well. It scans our security posture."
"The most valuable feature of Qualys Container Security is the detailed information in the reports and the remediation. This is done to make sure there are no vulnerabilities."
"The reporting functionality is great."
"It gives a very good overview of the inventory assessment process, and it can be accessed across our company because it's a global tool."
"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."
"We have around 500 virtual machines. Therefore, we conduct monthly scans and open tickets for our developers to address identified vulnerabilities. These scans cover the servers, other network equipment, and appliances in our infrastructure."
"The solution is the most dynamic one I have seen thus far."
"The most valuable feature of Tenable Nessus is vulnerability assessments. There are a lot of threats around the world and this solution is the first to come out with detection rules."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
"With the Tenable Nessus enterprise edition, you have unlimited licenses to scan the device."
"I am impressed with the tool's vulnerability scanning."
"The initial setup of Tenable Nessus is very easy."
 

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."
"The price could be better. Asset view is still a legacy feature. I'm not able to extract the information about the asset with complete details. It would be better if they fixed that in the next release. I know Qualys is already working on it, so I'm hopeful it will be available in the next five or six months. That would be something that's changed where I seek improvement."
"Qualys Container Security can improve the interface. It could be easier to navigate and be enriched."
"It would be nice to have an all-in-one solution that was automated and could handle the scanning and reports as well as the patching and updating."
"While Qualys VMDR is comprehensive, improvements in asset management functionality would be beneficial."
"Qualys doesn't have its own tool to deploy the agents all at once, so we need to use third-party tools such as BigFix or something else to deploy the agents, which is my main concern and should be fixed by the Qualys team."
"If anything, I would like to see the user interface modernized a bit more."
"Qualys does have an on-prem solution, but it is very expensive."
"Improve the API speed."
"Multiple user access would be an area for improvement from a user-access perspective. A role-based access control feature would be great because at present, there is a limitation with only one account. If that account gets compromised or gets locked, then we will encounter problems."
"The integration part is not good because five years ago, Tenable Nessus had more integration capability. After that, Tenable changed their policies and strategy."
"The solution could improve security updates."
"There is room, overall, for improvement in the way it groups the workstations and the way it detects, when the vulnerability is scanned. Even when we would run a new scan, if it was an already existing vulnerability, it wouldn't put a new date on it."
"Tenable Nessus could improve the price."
"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."
"There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."
"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."
 

Pricing and Cost Advice

Information not available
"Qualys VM is better suited for medium to large companies because the price can be too much for smaller customers."
"Qualys VM is reasonably priced."
"It is a high cost product. Compared to the other solutions, it is around 15 to 20% higher in cost."
"They have recently changed the pricing model, which is now better than it was before."
"The pricing is very competitive."
"Qualys Virtual Scanner Appliance isn't expensive right now. But the price for their product bundles could be better."
"When you want to cover yourself for scalability, you will be charged for the number you place on the scan itself."
"The tool's pricing is expensive and I would rate the pricing a seven out of ten."
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
"We pay approximately $2,500 on a yearly basis."
"The solution is expensive."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"The solution is worth the cost. It's a good investment."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"It has a fair cost and very good cost-benefit ratio."
"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."
