Sr Security Engineer at a tech vendor with 5,001-10,000 employees

Risk-based triage has transformed container security and now prioritizes high-impact threats

The best features Qualys TotalCloud offers currently include managing cloud infrastructure and container security while facing major challenges such as alert fatigue. Traditional vulnerability scanners flag hundreds of CVEs on short-lived Kubernetes containers, some of which have no internet exposure or are gone before we can even triage them. I leverage Qualys TotalCloud to move beyond static CVSS. I use it to implement runtime exposure, correlation risk reprioritization, and shift-left integration. This notifies developers to fix a base image upstream rather than patching live ephemeral instances. In my work with cloud and container security, the biggest operational hurdle was alert fatigue. I use Qualys to shift left from static CVSS severity to context-aware risk prioritization. I correlated raw vulnerability data with real-time risk factors such as public network exposure, active runtime execution, or overly permissive IAM roles. This allows us to immediately drop the priority of isolated containers and escalate lower-severity CVEs that sit on an exposed, high-risk path. We can map these findings directly back to our CI/CD pipelines so developers can patch the root base images upstream. We have drastically cut down the signal-to-noise ratio, saved a lot of manual hours doing triage work, and ensured engineering effort goes directly towards high-impact risk reduction.

Soc Analyst at a media company with 501-1,000 employees

Endpoint monitoring has become faster and has reduced alert response time for our clients

The best features that Alert Logic MDR offers include AI and behavior analysis, which I find most valuable. AI and behavior analysis mean that within AI there is static AI analysis and behavior analysis with subtypes. For example, if there is any file or a certain subtype, or if ransomware is happening, or any tool or app is being used, there are subtypes of AI. I appreciate that Alert Logic MDR has a separate AI for each type. Alert Logic MDR has positively impacted our organization by minimizing the alert SLA timing. When we used our other endpoint detection and response solution, we required at least fifteen minutes to raise one alert. After using Alert Logic MDR, we integrated it with SOAR technology, so within five minutes, the alert is raised to the client. Efficiency-wise, reducing the alert SLA timing to five minutes has been very beneficial. Whenever we receive an alert from endpoint detection and response from an endpoint to the Alert Logic MDR console, the system directly has the protect mode, conducting the kill and quarantine process itself. We only have to perform static analysis, and we have the playbooks, so they conduct some static analysis from there and directly raise the alert to the respective team.

Offers in-memory protection at a lower price than competitors

Morphisec's in-memory protection is probably the most valuable feature because it stops malicious activity from occurring. If something tries to install or act as a sleeper agent, Morphisec will detect and stop it. Morphisec's Moving Target Defense is critical to hardening our attack surface. If it detects something, it indicates whether it's valid. That means you've got a breach requiring investigation. It detects anomalies but doesn't necessarily point to what caused them. You still need to do that work. The solution is reasonably easy to administer. They made some changes last year, adding a cloud-based monitoring solution that makes deploying and monitoring our endpoints easy.

Quotes from Members

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

Pros

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

"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."

"The most valuable feature is extensibility."

"The best feature would be the ability to create policies. It is easy to control and update policies as required."

"The agent and agentless scanning in TotalCloud, particularly the FlexScan method, is incredibly valuable. With traditional scanning approaches, we had to give IP ranges and whitelist IPs. All that is now simplified. FlexScan requires minimal intervention, and after configuration, it automatically collects data and performs necessary scans."

"I found the initial setup user-friendly."

"Qualys TotalCloud has saved our time by giving us better asset visibility and risk-based prioritization, as it has reduced the time spent manually reviewing CVEs and deciding what to address first."

"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."

More Qualys TotalCloud pros

"We receive infrastructure security warnings from it. So, we know what is going on and what needs to be addressed."

"It has the ability to install agents, it is pretty straightforward, and you can automate the process pretty easily."

"The quicker implementation of changes to our infrastructure from Alert Logic tell us if there are any problems."

"Alert Logic MDR has positively impacted my organization as it has helped in detection of incidents and responding through our security team, who work around the clock."

"It is a very stable product."

"The installation and configuration were slick."

"The most valuable aspect of Alert Logic is its technology platform. They have SOCs in the US and Europe, giving them global visibility of the threat landscape. They detect and respond to threats in minutes. Their biggest value is human expertise. You're being attacked by a human, and you cannot respond to it unless you have a human on the other side. They have the human and technological resources to respond."

"The most valuable feature of the solution is endpoint management...The solution's support team is quite good at giving us feedback if there is an issue."

More LevelBlue Managed Detection and Response pros

"It provides full visibility into security events and from both solutions in one dashboard. I'm not a big security guy, if I have a threat that looks like there's a problem, I will ask Morphisec to dissect it for me, and tell me what might be happening. Because it tends to be all hash codes, so I can tell what's going on. They've been pretty good with that."

"Morphisec as the last line of defense is as good as you can get."

"Morphisec is a straightforward solution that is efficient and very stable."

"Morphisec gives me even more than Microsoft can give me, even if I were to pay."

"The biggest feature is that it hides everything from your operating system that's running in-memory from anything to try to run against it. That's the most unique thing that's on the market. There's nothing else out there that's quite like that. That's a big selling point and why we went with it. It does exactly what the design does. If you can't find it, you can't execute against it."

"Since we started using Morphisec, that hasn't happened even once."

"In a month, we are saving the effort of four to five days, and earlier we used to have a dedicated person and now we don't need a dedicated resource, which has reduced our security spending and we are saving approximately $600 a month."

"We haven't had any cybersecurity incidents on machines running Morphisec."

More Morphisec pros

Cons

"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."

"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."

"In my opinion, the combination of detection and protection features in Qualys TotalCloud cannot protect but can only detect."

"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."

"Qualys TotalCloud can be improved in the integration piece, especially with ServiceNow, where there's a bidirectional sync integrated, as there is no native capability from Qualys that can give monitoring metrics of how many assets came in and how many failed or were not properly reconciled or combined."

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

"There is room for improvement in the support."

"In a future release, I suggest that zero-day vulnerabilities should be predicted in advance using AI technologies. The system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."

More Qualys TotalCloud cons

"Alert Logic needs to expand its SOCs to serve more markets, such as the Middle East and Asia. There should be infrastructure that covers more time zones. The company should also develop an EDR that is natively integrated into their solution. Currently, a client must buy another EDR solution like CrowdStrike or Sophos. I think Alert Logic is developing this. Built-in email security could also be developed and integrated."

"Its menu is not very intuitive. I would like to see the user menu expanded a bit. The user menu is very layered, and because of the layers, you have to go down a path that is not very intuitive."

"This product needs to mature more. While it is a good product, there are some areas where it needs work."

"The interface, particularly the dashboard we use for looking at alerts, could be improved."

"For every new client or every new case, my company has to spin up a new instance, because of which there is a new URL."

"One major missing feature was the ability to see if vulnerabilities were exploitable, which required extra effort for us."

"It would be great to see more of an endpoint protector."

"I think Alert Logic MDR could be improved."

More LevelBlue Managed Detection and Response cons

"I haven't seen ROI because I haven't seen a threat that it has protected against, exactly."

"The dashboard is the area that requires the most improvement."

"In the Windows Defender integration, they have put in a report of computers that need Windows Defender updates. If those updates could be kicked off directly from the dashboard, instead of having to go to another system entirely, that would be good."

"We have discovered some bugs in the new releases that they've had to fix, so I would like to see more testing and QA on their side before they release."

"Having to have an on-prem server required a lot of administration."

"It would be nice if they could integrate Morphisec with other traditional antivirus solutions beyond Microsoft Defender. That is probably my biggest gripe."

"Those are some of the features that I was looking for on my on-prem platform that they've already instituted in the cloud and that I'm sure will be instituting on their on-prem platform as well. Having to have an on-prem server required a lot of administration. Being able to push that to the cloud and have it managed up there for us is a real nice addition."

"We started in the Linux platform and we deployed to Linux. The licensing of that has been kind of confusing between Linux licensing and Windows licensing. The overall simplicity of licensing or offering an enterprise license to just cover everything and then we don't have to count needs improvement."

More Morphisec cons

Pricing and Cost Advice

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

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

"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."

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

"TotalCloud's price is about right where I would expect it to be."

"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."

"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."

"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."

More Qualys TotalCloud pricing and cost advice

"Almost any product that is on the AWS Marketplace is super easy to subscribe to."

"Price of the solution was very reasonable considering the size of our organization at the time, and so it worked out perfectly."

"Alert Logic has better competitive pricing than some of its competitors."

"Its pricing is very reasonable considering what you get for what you pay. There is quite a good value there. Its licensing is also very logical. They've got the licensing price points at a reasonable level. It is on a monthly license but a yearly contract. There are no additional costs to the standard licensing fees."

"Our ROI would probably be zero. We don't even use it. It sits in there. We get emails and just delete them. Around the world, we don't even use it."

"Price-wise, Cybereason Managed Detection & Response is effective for larger companies, but if you have a small company with less than 1,000 employees, then it gets expensive."

"Our licensing is tied into our contract. Because we have a long-term contract, our pricing is a little bit lower. It is per year, so we don't get charged per endpoint, but we do have a cap. Our cap is 80 endpoints. If we were to go over 80, when we renewed our contract, which is not until three years are over. Then, they would reevaluate, and say, "Well, you have more than 80 devices active right now. This is going to be the price change." They know that we are installing and replacing computers, so the numbers will be all over the place depending on whether you archive or don't archive, which is the reason why we just have to keep up on that stuff."

"Licenses are per endpoint, and that's true for the cloud version as well. The only difference is that there is a little extra charge for the cloud version."

"It is priced correctly for what it does. They end up doing a good deal of discounting, but I think it is priced appropriately."

"Compared to their competitors, the price of Morphisec is not that high. You can easily deploy it on a large-scale or small-scale network."

"Price-wise, it's on the higher side. A traditional antivirus solution is cheaper, but in terms of security and manageability, its ROI is better than a traditional antivirus. I would recommend it to anybody evaluating or considering an antivirus solution. If your system gets compromised, the cost of ransom would be a lot more. This way, it saves a lot of cost."

"We are still using a separate tool. I know for our 600 or I think we're actually licensed for up to 700 users, it runs me 23 or $24,000 a year. When you're talking to that many users plus servers being protected, that's well worth the investment for that dollar amount."

"The pricing is definitely fair for what it does."

"It does not have multi-tenants. If South Africa wants to show only the machines that they have, they need their own cloud incidence. It is not possible to have that in a single cloud incidence with multiple tenants in it, instead you need to have multiple cloud incidences. Then, if you have that, it will be more expensive. However, they are going to change that, which is good."
