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.

Risk-based insights have transformed vulnerability triage and now guide focused remediation
Zafran Security adds context to vulnerability data. Instead of just showing a CVSS score, it helps identify which vulnerabilities are actually exposed and more likely to be exploited. In one recent project, we had a large number of critical findings, and Zafran Security helped us narrow the focus to a much smaller set of high-risk issues. That made it easier for the teams to prioritize the remediation and reduce the overall risk faster. The best feature for me is the risk-based prioritization. It helps separate the vulnerabilities that actually matter from the large volume of findings security teams deal with every day. I also appreciate the visibility it provides across different security data sources and the ability to focus remediation efforts on the exposures with the highest potential impact.

Quotes from Members

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

Pros

"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"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 has helped us view our risk structure, vulnerabilities, and security posture."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"Its dashboards are brilliant. It provides in-depth insights."
"The dashboards are particularly valuable as they offer a comprehensive view of the environment, highlighting any misconfigurations."
"The most valuable feature of Qualys TotalCloud is the visibility it provides."
"TotalCloud has been excellent in providing us with immediate access to all the products and features we need, such as CSPM, TruRisk Insights, and compliance reports, including CIS and HIPAA."
"Nessus is effortless to integrate."
"One thing that is important for us is that when the regulation agency is asking for something, we can send them reports from Nessus and they're very satisfied."
"The solution makes ransomware checking and OS auditing and implementation relatively easy."
"The features I personally like include host discovery."
"Security is complicated a subject. There's a lot involved in Tenable Nessus, but the solution is easy to run and manage and we have had a lot of good success with it."
"It gives you an unlimited IP scan."
"The most valuable features of Tenable Nessus are the scanning option. Advanced scanning is highly useful. The offline config audits and application assessments are useful."
"What I like most about Tenable Nessus is its vulnerability scanning feature."
"Zafran is an excellent tool."
"Zafran Security helped us to reduce the time spent prioritizing vulnerabilities and improve our ability to focus remediation efforts on the risks with the highest potential impact."
"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."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We saw benefits from Zafran Security almost immediately after deploying it."
 

Cons

"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"The price is very expensive, actually."
"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."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"There should be improvement from a dashboard perspective when collecting and showcasing data to lead management."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"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"
"Tenable Nessus could improve the reporting by adding some dashboards. The reports are a hassle at this time. Tenable.io has more detailed reports. Having a better dashboard that can show where the vulnerabilities are and be categorized would be helpful. We then could present them to upper management for a deep overview of our network posture which they do not see."
"While the solution is great for scanning servers, its features are limited when it comes to scanning network devices for vulnerabilities."
"Nessus is not very good at identifying web application vulnerabilities, which means that we need to buy another product like Acunetix or EMC Networker to handle that part."
"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."
"The price could be reduced."
"EQA's and dashboards should be addressed in the next release."
"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."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"I would like to see more dashboard customization and reporting flexibility."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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."
 

Pricing and Cost Advice

"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 price is reasonable."
"I think the price is fairly affordable. It provides a license that is fair."
