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.

Centralized threat detection has improved incident response and now reduces alert fatigue
SecureWorks Taegis VDR's best features include unified detection and response, as it pulls in alerts and logs from all my different tools such as EDR, SIEM, firewall, cloud services, and Windows machines, collecting everything into one clean dashboard where I can view all these items and eliminate the need to hunt through ten dashboards to piece a threat together. I find it very easy to navigate and customize the dashboard to fit my team's needs once everything is set up, and it is very simple to view the dashboard after setup. Cloud and hybrid support is another valuable feature of SecureWorks Taegis VDR, as it supports on-premise and cloud workloads, managing endpoints and network traffic to provide centralized visibility regardless of where my assets live, whether in the cloud or on-premise. SecureWorks Taegis VDR has positively impacted my organization because of its ease of use. The positive impacts include faster incident response, as I can detect, investigate, and contain threats much faster because it shows the full attack path in one place with deeper analysis of everything, and it reduces alert fatigue by consolidating alerts into one or two high-confidence incidents, which improves analysis efficiency and morale.

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.

Quotes from Members

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

Pros

"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"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 helps you not just to identify misconfigurations, but you can actually also fix issues."
"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"If I had to say something positive about the product that brings me the biggest benefit, I would say it has accurate reports, gets new update CVEs, zero-day attack detection, and is easy to manage with its GUI."
"I would rate Qualys TotalCloud ten out of ten."
"One of Qualys' best features is its categorization, which allows us to see the types of assets, their security postures, and the AI-powered version of the tool."
"It is a one-stop solution for different needs with separate APIs. The product offers different solutions for different companies."
"I chose SecureWorks Taegis VDR because I trust SecureWorks, having worked with McAfee, Symantec, Trend Micro, Kaspersky, Carbon Black, Cylance, CrowdStrike, Palo Alto Cortex XDR, and more, and I would say SecureWorks Taegis VDR is outstanding among all the other vendors in terms of functionality, ease of access, and UI friendliness."
"SecureWorks Taegis VDR's best features include unified detection and response, as it pulls in alerts and logs from all my different tools such as EDR, SIEM, firewall, cloud services, and Windows machines, collecting everything into one clean dashboard where I can view all these items and eliminate the need to hunt through ten dashboards to piece a threat together."
"Tenable Nessus is an absolutely stable and fantastic product."
"The best features of Tenable Nessus include its compatibility with other applications such as SIEM and other apps, allowing Tenable Nessus to work smoothly with them."
"My advice to people who are looking into implementing this product would be to just go ahead and do it."
"It is a mature tool."
"I can say that I am satisfied with Tenable Nessus' support and customer relations, which is why I'm still with the solution."
"Personally, I think Nessus is quite a good product."
"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."
"I would definitely recommend this solution; it's the best that I've used so far."
 

Cons

"I think Qualys TotalCloud needs to improve its handling of zero-day vulnerabilities and supply chain management because modern ransomware attacks not only target prime critical infrastructures but also the supply chain system."
"There is a lack of data segregation according to criticality or inventory."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"The cost of Qualys TotalCloud is high and could be more competitive."
"The main area needing improvement is integration. Although the team is strengthening TotalCloud, integration can be enhanced with SIEM, SOAR, ITSM, and other sources."
"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."
"Overall, we are satisfied with it. However, the response part of the Cloud Detection and Response (CDR) module can be improved. It is not yet in place according to requirements; it is not completely available even though the module has been released."
"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."
"SecureWorks Taegis VDR is very stable, though there is scope for improvement."
"There is always room for improvement in SecureWorks Taegis VDR, especially regarding user interface and navigation, as the platform is powerful but the UI can feel complex for new users."
"I would like to improve SecureWorks Taegis VDR by enhancing the dashboard to provide a holistic view with granular data."
"Some things in the user interface could be better. The user interface could allow more adjustments to plugins. The price could also be better."
"The support from Tenable Nessus is okay. However, they are sometimes slow and can take days to respond."
"One area with room for improvement is instead of there just being a PDF format for output, I'd like the option of an Excel spreadsheet, whereby I could better track remediation efforts and provide reporting off of that."
"Multiple user access would be an area for improvement from a user-access perspective. A role-based access control feature would be great because at present, there is a limitation with only one account. If that account gets compromised or gets locked, then we will encounter problems."
"There is room, overall, for improvement in the way it groups the workstations and the way it detects, when the vulnerability is scanned. Even when we would run a new scan, if it was an already existing vulnerability, it wouldn't put a new date on it."
"The solution should be able to support more devices."
"The report for counters is too simple and would be improved by a dashboard."
"It is expensive."
 

Pricing and Cost Advice

"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."

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

"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
"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."
"Cost-wise, it's an affordable tool."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
