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.

Endpoint monitoring has strengthened incident response and provides rapid isolation and forensics

Tanium provides an endpoint which is isolated from the network and environment. We can easily search its logs and history and connect remotely directly to that particular device which has been isolated from the network. We can search for the history and logs, including audit logs and event logs. The complete activity of the user or owner of the device is visible to us. We can see the artifacts of particular USB transfers internally for official use. We can not only connect remotely but also see the device status and how many failures have occurred within the network so far. We can see the IP address, how many times it has changed its IP address, and how many times it was connected to VPN or external VPN or internal VPN and what has been searched while on VPN. We can block the IOCs or IP addresses as well. We can block domains, hashes, SHA values, SHA-256, SHA-1, SHA-5 and MD5. Although I am not completely involved in the automation team, we do have that team and I have worked in some CERT recently. Tanium is more useful while we are in the CERT because most of the times when we are on high alert, Tanium does play a main role for that particular incident or any high case. Tanium is a simple tool and we can easily integrate it to many devices and it is a mandatory tool to secure an endpoint. It is mandatory to give any RDP connection and the tool should be present in the particular device. It is completely mandatory and it is in the policy as well.

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

"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 is an excellent platform, and the beauty of the platform is that we can get all the vulnerabilities, see all the reports in a single dashboard, view them segregated, and easily learn about critical, high, and medium findings with appropriately provided remediation steps."

"The most valuable feature is the consolidated information that it provides from various platforms."

"Qualys TotalCloud provides a single, prioritized view based on requirements such as identifying the most vulnerable assets and calculating the average time to remediate vulnerabilities."

"I would definitely recommend Qualys TotalCloud to other users."

"Qualys TotalCloud fulfills all these needs."

"I would definitely recommend it because it is easy to handle any cloud resources."

"Its excellent graphical interface makes the scanning process simple."

More Qualys TotalCloud pros

"Tanium is used for endpoint management, specifically patching and configuration management."

"The solution's technical support is very responsive."

"I would say Tanium is the best tool for vulnerability management."

"The insights we gain from our endpoints and the management capabilities that Tanium provides have been a boon to our operations and security."

"For incident response tasks, all these tasks can get done in minutes with minimal disruption to the end-user."

"Tanium’s best features include support for any Windows, Linux, or Mac endpoint, regardless of where it is, and the ability to do IT operations and security operations."

"I find the inventory and compliance features of Tanium to be the most impressive."

"Tanium is a simple tool and we can easily integrate it to many devices and it is a mandatory tool to secure an endpoint."

More Tanium pros

"The scanning capabilities are most valuable when compared to Nessus."

"My favorite part about Nessus is that you can customize the tool to scan exactly what you want. Microsoft releases new patches monthly on Patch Tuesday, and a lot of companies track that date. I set up Nessus for the day after Patch Tuesday to see which devices have already pushed those updates from Microsoft, so we can stay updated."

"We looked at Tenable, Qualys and Rapid7. We found Tenable was the best of all three."

"Tenable is the best vulnerability management product in the world, and I recommend it."

"The valuable feature for me is being able to ping the computers to do the automated scan and to come back and be able to see everything."

"Tenable Nessus is one of the best vulnerability assessment tools, that I know."

"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."

"The most valuable feature of Tenable Nessus is the self-updating engine."

More Tenable Nessus pros

Cons

"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"

"The support process is inefficient due to the excessive number of replies required when submitting tickets."

"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."

"Their customer support needs improvement."

"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."

"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."

"I would appreciate additional integration options to connect Qualys TotalCloud with our other vulnerability management tools."

"The support is not up to the mark and seems to be overburdened."

More Qualys TotalCloud cons

"Tanium required local admin or root rights on Mac devices, which did not comply with our security policies. This made the solution less suitable for our restrictive environment."

"There are downsides and drawbacks in Tanium, and there is room for improvement from my perspective."

"The most painful thing is the interface. It's a bit unclear sometimes."

"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."

"We set a policy to block USB access. The moment a device is being set up on the network, I apply the policy, but it does not come into effect immediately."

"The problem or challenge is a pre-sales and go-to strategy for the SMB market delivered through a channel or model. It's very convoluted and vague, which leads to some confusion about the various types of modules, and the device-to-seat cost is extremely difficult to calculate."

"The performance could improve in future releases. We have had performance issues in specialized web environments, but overall I think the problems are less than 2% of the computer systems being used."

"Tanium’s scalability could be improved."

More Tanium cons

"I face issues with Tenable Nessus sometimes due to upgrades."

"The support from Tenable Nessus is okay. However, they are sometimes slow and can take days to respond."

"One area that has room for improvement is the reporting. I'm preparing reports for Windows and Linux machines, etc. Currently, I'm collecting three or four reports and turning them into one report. I don't know if it is possible to combine all of them in one report, but that would be helpful."

"They have added a new Tenable Nessus Expert. That is their new product, which caters to the cloud and everything else. I am assuming that the new features and product enhancements are based on that tool set, but we haven't reviewed it yet."

"EQA's and dashboards should be addressed in the next release."

"There should be a possibility to install agents on scanned machines. Tenable IO provides the capability of using local agents to check local problems, but this feature is not there in Tenable Nessus Professional. It would be nice to have something similar in Tenable Nessus Professional. We should have the capability to use local agents installed on the machines to locally check a problem."

"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."

"Unfortunately, the solution consumes more system resources when it's being run and I'd like that to be reduced."

More Tenable Nessus cons

Pricing and Cost Advice

"The cost is high, but it meets our organizational needs."

"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."

"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."

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

"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 expensive."

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

More Qualys TotalCloud pricing and cost advice

"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."

"There is an annual license required to use this solution."

"It is higher than some competitors in the market."

"The solution offers value for money."

"The solution is expensive but it's a good investment."

"It's an expensive solution. It would be nice if the cost were lower."

"The product's pricing differs from region to region depending on negotiations and the number of endpoints."

"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."

"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 is reasonable."

"I would like to see better discounts."

"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."

"The price of the solution is reasonable."

"When comparing the price of Tenable Nessus to other similar solutions, such as Acunetix, Tenable Nessus is not as expensive. It is averagely priced in the market. We pay for the solution annually."

"The solution is worth the cost. It's a good investment."
