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inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages.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 Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are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.

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

"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."
"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."
"The best feature would be the ability to create policies. It is easy to control and update policies as required."
"The most valuable feature is the consolidated information that it provides from various platforms."
"Generally, Qualys is very good at detections, whether on cloud or on-prem, and the agent allows deployment on both infrastructures, providing continuous monitoring of your assets, which is a key selling point for us."
"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."
"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."
"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 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."
"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"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 scalability of the solution itself is unparalleled."
"The findings dashboards are neat and easy to understand, offering clear demarcations for different types of findings and detailed insights into specific vulnerabilities and their associated instances. It is not a place where everything is dumped together. It offers an easy-to-understand layout."
"It is scanning the whole repository for any sort of vulnerabilities, so it allows us to be more confident in our DevSecOps and not put a lot of folks or attention to it."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"The solution is great for scanning servers."
"With the Tenable Nessus enterprise edition, you have unlimited licenses to scan the device."
"Among the most valuable features are scanning for vulnerabilities and the reporting. The reporting templates are okay. I like that I can see all the hosts with different vulnerabilities."
"The most valuable features of Tenable Nessus include its ease of access and quick usability."
"Nessus has more plugins/add-ons, tests, and templates than previous tools and it is faster and customizable using CLI/API features, offering enough resources for an interesting cost-benefit rating and fewer false-positive events per type of asset while helping us quickly produce a QuickWin report that guided vulnerability management actions and plans for the next three to five years using the same tool, investment, and team for all companies in the group."
"Scanners and reports using CIS templates ("de-facto" standard, easy to fix and to locate correction tips at documentation), tests against cloud providers, database profiles, several types of telecom devices, and others highly customizable scans."
"The most valuable aspect of this solution is that you receive the entire report, which details the breakdown, especially in terms of critical, high, low, and mediums."
"The most valuable feature is how it scanned and detected through its database to let us know exactly what fixes we needed to put in place for the vulnerabilities. It detects and it also gives you the way to fix it."
 

Cons

"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"The support is not up to the mark and seems to be overburdened."
"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"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."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"I sometimes have difficulty detecting or uninstalling certain versions of applications, which I have to do manually."
"The other point is that the reporting features of Inspector need improvement. For example, I am in an organization with millions of CVEs, and getting an overview of all this is challenging."
"One area for improvement in Amazon Inspector is the automation aspect."
"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."
"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."
"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."
"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."
"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."
"Tenable Nessus could improve the price."
"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 Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"They should try to create an all-in-one solution."
"The reporting is a bit cumbersome."
"The pricing point has increased significantly in recent years. The product's pricing has roughly tripled within the last couple of years, making us reconsider renewing the license for the scanner."
"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."
"The support from Tenable Nessus is okay. However, they are sometimes slow and can take days to respond."
 

Pricing and Cost Advice

"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"Its price seems higher compared to other tools, but it is worth it. If they could adjust the pricing and make it comparable with other tools, that would be great."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"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 is very transparent and clear."
"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."
"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."
"It's priced according to market standards for its services."
"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"The solution is expensive."
"This solution is affordable."
"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
"The solution is worth the cost. It's a good investment."
"The price of the solution is reasonable."
"Nowadays, your vulnerability applications are going to be kind of pricey because lots of them, including Rapid7, are based upon a base price, but then they add in the nodes. That's where they get you. If you're a big network, obviously, you need to scan everything. Therefore, it's going to be costly. The risk and insurance money associated with having ransomware on my networks is going to cost me more money, time, and marketing than the price of the tool. That's why I'm speaking only as an information security officer to security operations. This is the tool that is there in my toolbox to say whether we vulnerable or not. At this point, I don't care about how much it costs my company to have it because if I wasn't able to report it and we got ransomware, then who cares? I'm probably going to be out of business because it happened. That's why I don't care about the price. I have it, and I could use it effectively and do my report. At the end of the day, even if we get ransomware, as long as I reported it, followed my protocol, and put in the change, irrespective of whether it was ignored or denied, I did my job."
"Our organization is huge so our license costs $30,000."
