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.

Continuous risk-based monitoring has strengthened incident response and vulnerability prioritization
I haven't explored Qualys VMDR's vulnerability lifecycle automation yet. One of my analysts mentioned that queries lack grouping operators in Qualys VMDR. From my experience, I would appreciate improvements in the query options in Qualys VMDR, specifically in the query-building process where I would need more features and operators. Additionally, we have been facing issues with Qualys on the cloud level. We cannot download the configuration profile from the cloud agent, and it is showing a pending action for download. During 2025, we noticed outages of Qualys a couple of times. I want to mention that there is an issue with receiving timely RCA deliveries. While this is not necessarily about the tool, it relates to support. The support has not been very responsive, and we are receiving RCAs a little delayed whenever we raise support cases or communicate with the TAMs. Additionally, the UI has a slight latency, which I and my team have experienced. They have also reported this latency issue when navigating through different pages.

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."
"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."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We saw benefits from Zafran Security almost immediately after deploying it."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"I find Qualys VM very robust, and it's very useful for vulnerability management and patch management. The value that it brings to my environment is economies of scale. There is no limitation on adding any endpoints. You go by the rule, and it's added once another endpoint is added to our environment. It's automatically installed, and it's less work from our end. It frees up my license automatically if I don't need an endpoint or if my machine is decommissioned. I like the dashboard displays because I don't see any duplication. The most important part is vulnerability management and prioritization. Unlike Symantec, it shows the kind of vulnerability I would want to patch first. It provides a holistic view of the kind of vulnerabilities and the ones I should remediate first. I don't have to do a scan; it just brings up those critical kinds of vulnerabilities like zero-day vulnerabilities and tells me to prioritize them. You have to prioritize these vulnerabilities first and go on with the rest. The dashboard shows me the ones that have been fixed, so I don't have to complete an aging report. The user experience and the graphical interface are good. As it's user-friendly and understandable on an executive level, it brings real value. We also use this solution because it's robust and flexibile."
"The reporting is fine."
"Qualys VM had a recent upgrade and the newer version is supporting the cloud."
"Qualys VMDR is easy to understand and provides detailed reports."
"Qualys VM is very stable."
"The solution is easy to use."
"Overall, the solution is highly rated because of its simplicity and efficiency."
"The most recent is VMDR, which provides a comprehensive overview of how to detect, patch, and remediate specific vulnerabilities."
"The most valuable feature of Tenable Nessus is the dashboard. They are convenient to use."
"The solution is great for scanning servers."
"It gives a holistic view of your entire environment."
"Tenable Nessus has provided increased visibility across the organization's servers."
"User friendly and good dashboards."
"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."
"Tenable integrates well with other solutions such as SIEM and batch management."
"I like the fact that it was not expensive. I like that it's user-friendly."
 

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."
"The support has not been very responsive, and we are receiving RCAs a little delayed whenever we raise support cases or communicate with the TAMs."
"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 scanner doesn't pick up every vulnerability, so we have to use multiple scanners to cover that gap."
"The solution is a bit expensive if you do not have access to discounts."
"The reporting section needs improvement as running reports can take several hours."
"Qualys VMDR is basically susceptible to false positives, and false negatives."
"The response time of technical support takes a while."
"Qualys should improve their customer experience. They need to improve the tech support experience and the turnaround time."
"It would be a good idea if they have a simulation of attacks or a use case for finding a new vulnerability or dealing with a zero-day attack."
"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 is not feasible for a large company."
"The solution could improve security updates."
"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."
"The product must be more comprehensive."
"The interface is a little bit clunky, and the reporting is not marvelous. There should be better integration of reporting between instances. Currently, the instance stands alone, and it produces a report. Being able to amalgamate those reports with another instance will be useful."
"I have found it is sometimes difficult to control the Zoom meeting sessions. For example, it is difficult to know who is talking and when trying to mute everyone but the speaker you end up muting everyone. When using multiple screens it is laborious to find the control buttons, such as to start a session. Additionally, when a recording is done I have found it difficult to find them, there should be an easier way to retrieve them."
 

Pricing and Cost Advice

Information not available
"Qualys Virtual Scanner Appliance isn't expensive right now. But the price for their product bundles could be better."
"It is more expensive than other products on the market."
"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."
"Usually every implementation is different and the quote is in function of number of assets."
"Qualys VM is reasonably priced."
"The solution is expensive."
"The solution is costly."
"We have an annual contract for Qualys VMDR. I believe it's for either two years or five years."
"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."
"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"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 is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"I rate the product's price seven or eight on a scale of one to ten, where one is low price and ten is high price."
"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."
"When comparing the price of Tenable Nessus to other similar solutions, such as Acunetix, Tenable Nessus is not as expensive. It is averagely priced in the market. We pay for the solution annually."
