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.

Helps us minimize attack surfaces by identifying root accounts and encryption issues
TotalCloud provides written explanations to guide remediation and eliminate cyber risks. While all cloud platforms offer security features, it's challenging to consolidate them into a single dashboard. Qualys TotalCloud effectively addresses this by consolidating multiple cloud platforms and subscriptions onto one dashboard. This allows users to quickly identify and mitigate misconfigurations and risks, simplifying security management. Before implementing TotalCloud, our compliance rate was approximately 50 to 60 percent. However, after adopting the platform, it has increased to 80 to 90 percent. TotalCloud also helps us minimize attack surfaces by identifying root accounts and encryption issues, thereby enhancing our overall security by 40 percent. TotalCloud offers a unified platform for assessing vulnerabilities and threats across both IaaS and PaaS environments. This unified view has improved our cloud security posture management. We gain a single, prioritized view of risks through TotalCloud's TruRisk Insights feature. This feature considers not only the QDA score but also factors in cost and other relevant elements to provide a comprehensive risk assessment. From a potentially overwhelming list of findings, TruRisk Insights prioritizes the most critical risks, allowing us to focus our efforts and resources on addressing these high-priority tasks efficiently. A single, prioritized view of risk streamlines the risk assessment process by eliminating the need to consolidate multiple sources. This comprehensive view is instrumental in communicating with other business customers who may be unaware of potential risks or misconfigurations within their resources. By identifying and informing them of these issues, we can guide them towards compliance and ensure a more secure environment. TruRisk Insights provides valuable findings by identifying vulnerabilities and misconfigurations, displaying them on a dashboard, and offering deeper insights into the attack surface. It analyzes not only internet-facing devices but also those indirectly connected, providing a comprehensive understanding of potential risks. This is crucial because even devices not directly connected to the internet can be vulnerable if they have an attack surface. TruRisk Insights also offers mitigation strategies, making it a highly useful tool for managing security risks. With the VMDR feature enabled and the Qualys Agent installed on various assets, we can identify existing vulnerabilities. TruRisk Insights then calculates risk scores, prioritizes tasks, and presents the number of findings. This allows us to focus on mitigating high-priority vulnerabilities while deferring those with lower priority, ultimately reducing overall risk. TruRisk Insights provides device details, allowing for containerization of misconfigured devices. This process involves isolating problematic devices and rectifying misconfigurations, ultimately enhancing our security posture.

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

"We saw benefits from Zafran Security almost immediately after deploying it."
"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."
"Zafran is an excellent tool."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"Qualys TotalCloud's most valuable features are its security capabilities that help identify and mitigate risk factors."
"The best feature would be the ability to create policies. It is easy to control and update policies as required."
"CSPM is currently the most used feature, and we are enjoying the new feature, FlexScan, which is valuable for Internet-facing VMs."
"I like the web API security and IoT scanning features the most. The user-friendly design of TotalCloud's interface enables customers to navigate it and use its full potential easily"
"The most valuable feature of Qualys TotalCloud is the visibility it provides."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"I would definitely recommend Qualys TotalCloud to other users."
"The results are not that bad, but the key selling point is that it is an affordable tool set."
"We have done code scanning for a long period because as a company, we do DevOps as part of our development life cycle."
"Easy to set up vulnerability scanner with good stability and a responsive technical support team."
"Tenable Nessus is one of the best vulnerability assessment tools, that I know."
"The vulnerability scanner is the most valuable feature."
"I have found the vulnerability assessment and the reports to be useful."
"It is easy to deploy and easy to use. Its reporting is good. From this reporting, you can see the pain point in your network, which makes it easy to fix them. It is easy to understand the reports and export them."
"The most valuable feature of Tenable Nessus is the dashboard. They are convenient to use."
 

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."
"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 system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."
"Their customer support needs improvement."
"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."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"It has been working very well, but it would be helpful if the dashboard could generate reports tailored to specific compliance needs. For example, in India, we have to comply with RBI and SEBI guidelines. It w"
"In TotalCloud, I would suggest improvements in policy checks to cater to various inventory types like VPCs, subnets, S3 buckets, or IAMs. There is a lack of data segregation according to criticality or inventory."
"The cost of Qualys TotalCloud is high and could be more competitive."
"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"The reporting is a bit cumbersome."
"You can scale Nessus to the extent that you can afford it. You need to have a license for every device you scan. As long as you can afford the increased costs, you won't have a problem scaling it."
"Lacks some penetration testing-related services."
"The reports should be improved in Tenable Nessus. For example, when you are auditing compliance with CIS standards. It provides very poor reports."
"The user interface of Tenable Nessus feels outdated and could be more user-friendly."
"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 accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"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
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"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."
"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."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"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."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"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."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
"The price is reasonable."
"The pricing is much more manageable versus other products."
"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."
"The price of Tenable Nessus could improve, it is expensive."
