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.

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.

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

"I rate the breadth of FlexScan in providing visibility into on-premises, multicloud, and container environments as fantastic."
"Qualys TotalCloud provides a single, prioritized view of risk, reducing the workload associated with consolidating multiple sources for risk prioritization."
"Once it is set up, Qualys has proved to be one of our greatest assets."
"TotalCloud provides the easiest and the best approach for cloud infrastructure management."
"Vulnerability and threat detection and assessment of the criticality of the vulnerabilities exposed are most valuable."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"I would definitely recommend Qualys TotalCloud to other users."
"The solution is great for scanning servers."
"The interface is excellent; it makes it very user friendly and easy to navigate for the most part, and the product is pretty problem-free so we don't have any real issues with it."
"I find the features that are most valuable are the policies that help us identify the vulnerabilities. These policies are then used for scanning instabilities and then identifying the particular vulnerabilities."
"We can now deliver highly professional consulting using the product."
"The scanning and reporting features are the most valuable aspects of Tenable Nessus."
"We have done code scanning for a long period because as a company, we do DevOps as part of our development life cycle."
"The solution is very good at vulnerability management."
"Nessus is good at finding out what nodes you have in place. It will then provide you a report, by node, of what the vulnerabilities are. It does it quickly and stealthfully."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"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 is an excellent tool."
"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."
 

Cons

"Customer support with Qualys TotalCloud needs a little improvement with the response times."
"TotalCloud could improve its scanning of niche devices like Wi-Fi dongles and USB modems because they are often untested. It covers everything else, like laptops, mobile devices, and Bluetooth IoT devices. They can improve on the small IoT devices because hackers and testers use these."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"There is room for improvement in vulnerability scanning, particularly for PaaS environments. Currently, Qualys does not have full access to these instances, which limits its effectiveness."
"I sometimes have difficulty detecting or uninstalling certain versions of applications, which I have to do manually."
"The cost of Qualys TotalCloud is high and could be more competitive."
"Qualys TotalCloud can be improved in the integration piece, especially with ServiceNow, where there's a bidirectional sync integrated, as there is no native capability from Qualys that can give monitoring metrics of how many assets came in and how many failed or were not properly reconciled or combined."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"Tenable Nessus provides observations but offers limited information about solutions."
"Multiple steps to create an actionable plan will be a great addition to Nessus."
"Based on my experience, the pricing for Tenable Nessus is somewhat higher, but customers still want to pay for it, so it remains acceptable."
"It would be nice for the professional module to include some of the reports available in the expert module."
"I would like to have a management option after the network scanning."
"Technically, it is an excellent and the best solution available in Libya. My only concern is related to its pricing. They are an emerging company in Libya, and they need to put in some effort to provide us with very good prices so that customers can go with the best solution. Chinese companies are getting into the market here, and they're providing very cheap solutions."
"Tenable Nessus is very costly compared to OpenVAS and sits on the higher side."
"They need more flexible pricing."
"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."
 

Pricing and Cost Advice

"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"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."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"Qualys TotalCloud is expensive."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
"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."
"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."
"I would like to see better discounts."
"The price of the solution is reasonable."
"The newer tools are quite pricey. There is a case of some fine tuning that can be done in terms of licensing. The IP based licensing that is offered makes the tool very expensive. If they want the IT industry to adopt it, the price should be looked at."
"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."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
