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.

Automated insights streamline data security assessment
For Amazon Inspector, we have many EC2 or virtual machines deployed inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages. As we progress with time, this package needs to be updated for security enhancement, which requires us to uninstall the package, install the new version, and then we should be fine. However, the challenge comes with how to scan all our EC2 instances for security vulnerabilities, which is currently managed by Amazon Inspector. Amazon Inspector can scan EC2 instances or ECR, which is the ECR registry where we can save artifacts Docker images. Amazon Inspector can also scan Docker images uploaded to ECR for Elastic Registry service, and it can scan databases and S3 based on the latest updates. I noticed this from a couple of months ago, and it provides huge benefits for security. Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are causing security concerns. Amazon Inspector can list these security concerns and offer guidance on how we can remediate it by updating the package to a specific upper version or something similar.
Brent Hamlin - PeerSpot reviewer
Infrastructure Manager at a construction company with 501-1,000 employees
Continuous threat scanning has improved remediation time and strengthened executive reporting
The best features that The NodeZero Platform by Horizon3.ai offers include the automated scans, which are great to use; you set it, scope it, and let it go, which works really well. The executive reporting feature is impactful for me as a manager, providing a strong foundation to give quarterly and yearly reports to our executives and board to see the state of our infrastructure from a security standpoint. The level of detail and clarity in the executive reports from The NodeZero Platform by Horizon3.ai absolutely helps me communicate effectively with leadership. They are detailed enough for me to extract the necessary information tailored for the executives and to provide a broader perspective on our mitigation efforts or accepted risk stance and where additional controls exist. The NodeZero Platform by Horizon3.ai has positively impacted my organization by giving us a better continuous picture of our security posture, what's exploitable, and what can be used against the organization. It allows us to run scans whenever needed, unlike a single third-party system that only provides a snapshot in time; our processes must be ongoing as the security landscape is dynamic. NodeZero's endpoint security effectiveness feature impacts my understanding of potential security threats by providing a clear picture of both the external and internal landscapes within my organization, enabling me to prioritize and adjust as needed for vulnerabilities such as WordPress plugin issues or user enumerations and software code version assessments. I have built The NodeZero Platform by Horizon3.ai into our weekly and monthly workflows for security CI/CD, and we scan our externally accessible assets every week to address anything quickly if it comes up. That includes our firewalls, websites, and anything that is an external web server, which we scan weekly, while the monthly scans are for internal systems that feed our security CI/CD pipeline, enabling us to action across and prioritize any vulnerabilities caught by The NodeZero Platform by Horizon3.ai.

Quotes from Members

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

Pros

"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."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"The best features in Qualys TotalCloud include the total asset management of the cloud environment. It is very easy to export the report and see the vulnerabilities related to the cloud specifically."
"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."
"The most valuable feature of Qualys TotalCloud is the visibility it provides."
"I would definitely recommend it because it is easy to handle any cloud resources."
"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"I highly recommend Qualys TotalCloud to other users."
"The integration of Amazon Inspector with other AWS services has enhanced our security. Security Hub is a major asset because it allows us to centralize data from various AWS services. We can integrate third-party tools as well. It is just a single-click option."
"The vulnerability discovery is valuable, and they also rank those vulnerabilities for you. So, you could rapidly attack some of the higher, severe vulnerabilities as they pop up, if they do pop up."
"The automated vulnerability detection aspect is most valuable."
"The scalability of the solution itself is unparalleled."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"The assessment reports provided by Amazon Inspector have helped me in identifying security vulnerabilities in my cloud applications by giving us a nicely designed dashboard that provides all the security information we need to work on remediation."
"My experience with AWS technical support is very good, I didn't face any specific challenges, and even the documentation of AWS is good for both Microsoft, which is Azure, and AWS."
"The most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."
"I rate the stability of the NodeZero Platform a ten out of ten."
"The NodeZero Platform by Horizon3.ai has positively impacted our organization by definitely increasing our security posture significantly."
"The NodeZero Platform by Horizon3.ai is better than manual penetration test scans, definitely worth trying if you are considering using it because it reduces the time and cost associated with manual scans and presents the data in a very clear way that even non-technical people can understand."
"Otherwise, the solution itself is very fine and I would recommend it as an MSP partner or as a user of the tool to pretty much any company."
"The NodeZero Platform is amazing; what I love most about it is that it's automated and comparable to the manual pen testing we did with a third-party company, but with the added benefit of unlimited retesting to validate fixes."
"We experienced a threat that could have severely crippled us, but we were able to shut it down before it escalated, thanks to internal vulnerability testing and addressing critical vulnerabilities using their tool."
"The NodeZero Platform by Horizon3.ai has positively impacted my organization by catching vulnerabilities and exploits that we wouldn't otherwise be able to find as easily or as quickly, so I'd say it helps better our cybersecurity posture."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
 

Cons

"The response part of the Cloud Detection and Response (CDR) module can be improved."
"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"There is room for improvement in the support."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"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 cloud licensing unit system is unclear, especially since "units" aren't well-defined."
"One major area for improvement is remediation. My team works on remediating findings over time, likely using available patches. However, easier integration with Amazon's patching services would be very helpful."
"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"The false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning."
"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."
"It has a limited scope. So, AWS Inspector primarily focuses on the security of the EC2 instance. So, if your architecture includes other AWS services, then you may need to use additional tools for your comprehensive security assessment. So that is one con. Another is, like, we have a dependency on agents."
"There isn't too much to improve right now. Scanning on demand or as a part of the pipeline versus a post pipeline solution would be good, but it is not a deal breaker by any means."
"One area for improvement in Amazon Inspector is the automation aspect."
"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"The areas for improvement for The NodeZero Platform involve integration and automation. It would be beneficial if it could integrate directly with vulnerability management tools that would allow the platform to automatically import data, identify vulnerable systems, and test targets immediately, potentially even enabling automated feedback loops for rescanning since the process is currently manual."
"The NodeZero Platform by Horizon3.ai could be improved by speeding up the time from initializing a test to actually starting the test, as the deployment of the underlying infrastructure can take several minutes, sometimes over 10 minutes."
"I feel there could be improvements in scalability, although at this point I have no specific negative points to report."
"I would like to see an improvement in the notification management."
"The NodeZero Platform by Horizon3.ai can be improved in some ways, particularly regarding the test scan sometimes."
"Occasionally, I will get one that does not offer a lot in the way of specific steps because the device on which it found the vulnerability is not a standard device that it recognizes."
"I haven't really come across anything that I say needs to be improved with it, other than the container runner, which tends to lose time."
 

Pricing and Cost Advice

"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"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."
"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."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"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 is expensive, but it offers a premier solution with no headaches."
"It's priced according to market standards for its services."
"The pricing is very transparent and clear."
"It is scaled as you go. There are probably a certain number of scans per month, and there are tiers. If you're under a certain tier, it is free. The second level is pennies, and then all the way up to like a million. So, it has a tiered pricing program. They're pretty good with your initial scanning, and there is room to scale based on being affordable, but it is fairly cheap. There are no additional costs. They pretty much think about it as a pay-per-scan type model."
"The lowest cost would be around $10 for a few small accounts, however, for thousands of accounts, it could be around $5000 to $6000 dollars per month."
