Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

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 would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"TotalCloud offers a comprehensive suite of features, including EDR, XDR, and TrueRisk, providing a centralized platform for managing vulnerabilities and security risks."
"If someone were to ask me to review Qualys TotalCloud, I would summarize it as an end-to-end solution for cloud security with visibility and governance-grade controls without needing to manage multiple disconnected tools."
"Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution."
"While automatic inventory detection upon connection is a helpful feature, a truly valuable capability would be assessing an environment's security posture against Azure and CIS best practices."
"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."
"Qualys TotalCloud provides a single, prioritized view of risk, reducing the workload associated with consolidating multiple sources for risk prioritization."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"Tenable Nessus has helped us with better visibility of the current security posture of our infrastructure and helped us be proactive about remediating those findings."
"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."
"Tenable Nessus streamlines the process of scanning for our organization."
"What I like most about Tenable Nessus is its vulnerability scanning feature."
"The initial setup is very straightforward."
"The results are not that bad, but the key selling point is that it is an affordable tool set."
"The most valuable feature is the installation of Tenable which is incredibly easy."
"It provides multiple recommendations towards the remedy of vulnerabilities."
"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."
"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."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
 

Cons

"There should be improvement from a dashboard perspective when collecting and showcasing data to lead management."
"The areas in the solution that have room for improvement include the UI/UX design, which should be improved, and they should integrate more artificial intelligence into the product."
"Enhancing clarity regarding its compliance capabilities would be beneficial, as the current scope is limited in geographic coverage."
"To be honest, I would move out from this tool because it does not give a full view of vulnerability."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"TotalCloud could improve the classification of vulnerabilities. Specifically, it could enhance the categorization of what aspects fall under patches resolved by OS or software updates and what pertains to configuration adjustments."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"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."
"Technical support could be more knowledgeable. Their support right now goes from awkward to funny."
"We'd like to see the solution embrace more user-friendliness."
"In Nessus Professional, the main drawback was that we could have a single-user login password. So it could be better in terms of security."
"The professional version is not very scalable. It's not really scalable considering the number of assets and clients that I have."
"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 for improvement in finishing the transition to the cloud. We'd like to see them keep on improving the Tenable.io product, so that we can migrate to it entirely, instead of having to keep the Tenable.sc on-prem product."
"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."
"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

"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."

"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."

"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"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."
"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."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"There is an annual license required to use this solution."
"The price of Tenable Nessus is too expensive for each service center."
"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."

"Cost-wise, it's an affordable tool."
"The product is free."
