Sr Security Engineer at a tech vendor with 5,001-10,000 employees
Risk-based triage has transformed container security and now prioritizes high-impact threats
The best features Qualys TotalCloud offers currently include managing cloud infrastructure and container security while facing major challenges such as alert fatigue. Traditional vulnerability scanners flag hundreds of CVEs on short-lived Kubernetes containers, some of which have no internet exposure or are gone before we can even triage them. I leverage Qualys TotalCloud to move beyond static CVSS. I use it to implement runtime exposure, correlation risk reprioritization, and shift-left integration. This notifies developers to fix a base image upstream rather than patching live ephemeral instances. In my work with cloud and container security, the biggest operational hurdle was alert fatigue. I use Qualys to shift left from static CVSS severity to context-aware risk prioritization. I correlated raw vulnerability data with real-time risk factors such as public network exposure, active runtime execution, or overly permissive IAM roles. This allows us to immediately drop the priority of isolated containers and escalate lower-severity CVEs that sit on an exposed, high-risk path. We can map these findings directly back to our CI/CD pipelines so developers can patch the root base images upstream. We have drastically cut down the signal-to-noise ratio, saved a lot of manual hours doing triage work, and ensured engineering effort goes directly towards high-impact risk reduction.

Hybrid deployments have strengthened vulnerability visibility and streamlined security reporting
I would not personally speak to what I like about Tenable Nessus, because I think the only reason many customers are using it is because it is well-known and they have received directives from their companies or mother companies. For me, the key value is the ease of use and integration with SIEMs because it has built-in integrations with IBM QRadar and others. Tenable Nessus is typically a widely integrated tool within the existing security ecosystem. It is part of the security policy that customers have implemented, so it does provide positive impact and is beneficial to use Tenable Nessus.

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.

Quotes from Members

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

Pros

"Qualys TotalCloud's most valuable feature is its agent versatility."
"One of the most valuable features of Qualys TotalCloud is FlexScan, which is specifically for internet-facing VMs. We found this feature to be very useful. It was a key differentiator for us."
"I highly recommend Qualys TotalCloud to other users."
"Its excellent graphical interface makes the scanning process simple."
"I appreciate TotalCloud's real-time protection and remediation features. The remediation options include automated one-click remedies and custom changes that help manage vulnerabilities efficiently."
"Having everything in a single place to look for it and a single integration into ServiceNow has been the big transformation."
"The best part I like is the on-demand scans."
"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."
"Personally, I think Nessus is quite a good product."
"Nessus is effortless to integrate."
"The solution is the most dynamic one I have seen thus far."
"The scanning capabilities are most valuable when compared to Nessus."
"Tenable integrates well with other solutions such as SIEM and batch management."
"The solution makes ransomware checking and OS auditing and implementation relatively easy."
"I am impressed with the tool's vulnerability scanning."
"The most valuable aspect of this solution is that you receive the entire report, which details the breakdown, especially in terms of critical, high, low, and mediums."
"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."
"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."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Zafran is an excellent tool."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
 

Cons

"Enhancing clarity regarding its compliance capabilities would be beneficial, as the current scope is limited in geographic coverage."
"One thing that could be improved is the user experience and navigation."
"In a future release, I suggest that zero-day vulnerabilities should be predicted in advance using AI technologies. The system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."
"I chose a rating of nine out of ten because there is a complex interface that sometimes overwhelms new engineers."
"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"The response part of the Cloud Detection and Response (CDR) module can be improved."
"The reports should be improved in Tenable Nessus. For example, when you are auditing compliance with CIS standards. It provides very poor reports."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features."
"We feel the solution's technical support to be very bad."
"Tenable Nessus is very costly compared to OpenVAS and sits on the higher side."
"I would like to have a management option after the network scanning."
"We'd like to see the solution embrace more user-friendliness."
"The reports are okay, but the interface is a bit difficult to navigate in some cases."
"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 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."
 

Pricing and Cost Advice

"Its price seems higher compared to other tools, but it is worth it. If they could adjust the pricing and make it comparable with other tools, that would be great."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"I am not sure about the pricing. From what I understand, it is a bit on the higher side, but I do not have the exact numbers."
"Qualys TotalCloud is expensive."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"Although Qualys TotalCloud is relatively expensive due to its unique automation features, its cost-effectiveness is rated an eight out of ten, with ten being the most costly."
"The cost is high, but it meets our organizational needs."
"TotalCloud's price is about right where I would expect it to be."
"There is an annual license required to use this solution."
"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."
"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."
"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."
"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."
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"I would like to see better discounts."
