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.
Harold Jensen - PeerSpot reviewer
Good visibility but expensive and needs better support
Support: It's often overseas and often following a script, basically asking us to redo what we opened the case with. Multiple APIs: There seems to be a lack of easy onboarding into Qualys. We had to use manual inputs and some API calls to get items in place. Dashboard: It is very rudimentary with very little customization. The Qualys Scripting Language (QSL) works differently in different Qualys modules, so when you get it working in one area you have to modify the syntax in others. User account management: We often have to give users more rights than needed just to give them what they need. Integration with the various Qualys Modules: You can tell the UI is different based on of the different teams that created them. QSL syntax same in all modules Responsiveness of some of the components: They time out, you get a blank screen, etc. Backend updates between the various modules: You update connectors and information takes a few minutes to show in VMDR or Global Asset View Connectors: Connectors have a throttling issue with AWS which causes them to frequently fail unless you manually run them again.

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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"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."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Monitors workstations and servers for vulnerabilities and creates reports."
"Qualys VMDR provides us with a quick response to threat findings through regular scheduled scanning, which improves our security operations."
"Qualys VMDR provides a real-time response and reporting feature, which is excellent."
"This is one of the best products I have worked with so far. I like the power of Qualys, and it's a better solution because you can scan a compact file, a BIT file, or batch files. The product already knows what's happening inside, and you don't need to expand the package. Tenable will do the same thing, but you need to have a package issuance claim. With Qualys, we can immediately understand the file, even a compact file. If there's some kind of discovery or incident, you will know what happened in the environment."
"The most valuable features of Qualys VM are its ability to do proper vulnerability assessment. It has a lot of updates for all the vulnerability databases from all over the globe. It's an amazing solution when it comes to the versatility of the features it has. Additionally, the reports are very good. It generates very detailed reports about the vulnerabilities inside the environment"
"I find the solution's dashboard interesting...The response time is fine. You can pull up reports without dragging or consuming bandwidth."
"The most valuable features are vulnerability detection and the scanning capability to enable identification of vulnerabilities across our network."
"I like the automated report generation and vulnerability report generation."
"The most valuable feature is the installation of Tenable which is incredibly easy."
"Overall Zoom is a good solution."
"It also has an executive report where you don't have to provide the client all the detail for them to sift though. But if they wish to dig through the detail they can."
"Security is the key number because it can start to scan with a few clicks instead of credits, which is a bit complicated. So simplicity is the first advantage. Then the generated reports are well done and easy to present to management. The quality of the scan is quite good in detecting the severity. The solution has simplicity. Also, it has frequent updates so that is also a valuable feature."
"The solution is great for scanning servers."
"The product's most valuable features are vulnerability and asset management. It can define the rules and validate the configuration."
"The most valuable feature of Tenable Nessus is the GUI and user-friendliness. Additionally, the environment is easy to work with."
"Tenable Nessus streamlines the process of scanning for our organization."
 

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."
"It is more expensive vs. other products on the market."
"They're still evolving their platform in terms of reporting capabilities."
"They can tweak their UI since the new version seems a bit jumbled up, and the old UI was more user-friendly."
"Qualys VM's vulnerability scan could be improved, especially the number of CVE numbers it can manage at a time."
"Qualys should improve their customer experience. They need to improve the tech support experience and the turnaround time."
"The customer support is very bad."
"It would be helpful to have features for better tracking, including options for adding relevant owners or supporting groups for each asset."
"Qualys VMDR identifies vulnerabilities and suggests fixes. However, it does not automate patching unless the patch management module is purchased separately."
"The user interface of Tenable Nessus feels outdated and could be more user-friendly."
"There should be a possibility to install agents on scanned machines. Tenable IO provides the capability of using local agents to check local problems, but this feature is not there in Tenable Nessus Professional. It would be nice to have something similar in Tenable Nessus Professional. We should have the capability to use local agents installed on the machines to locally check a problem."
"They should try to create an all-in-one solution."
"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."
"Consumes more system resources when it's running."
"In terms of what could be improved, I would say its reporting portion."
"One area with room for improvement is instead of there just being a PDF format for output, I'd like the option of an Excel spreadsheet, whereby I could better track remediation efforts and provide reporting off of that."
"It wasn't very clear how the scripts are running the scans. There's information about the script but it's not straightforward. The script information for each of the plugins should be available, but it doesn't give us straightforward direct information about how it was executed. That needs to be more clear."
 

Pricing and Cost Advice

Information not available
"There are no additional fees in addition to the standard licensing fees."
"Qualys VM is better suited for medium to large companies because the price can be too much for smaller customers."
"The solution is expensive."
"We do see over $100,000 in terms of price, for mid-size programs. You likely will pay more than $100,000 without any discount. It is a bit pricey."
"The solution is reasonably priced for the value it provides."
"It is different for every company, but for us, it's every three years."
"When you want to cover yourself for scalability, you will be charged for the number you place on the scan itself."
"Qualys is cheaper and more affordable than other solutions."
"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."
"We paid about six thousand dollars per license."
"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
"Our organization is huge so our license costs $30,000."
"Cost-wise, it's an affordable tool."
"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."
