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.

A scalable SaaS based platform that helps with cyber threat intelligence and automated hunting

I would rate Cisco SecureX a ten out of ten. I find the product to be a fantastic platform. If you are eligible, start using it straight away. The best way to evaluate it is to start using it and see where it fits within your organization. I think it helps our customers really deliver their SecOps goals, and I see it as a core foundation of CAE's own security strategy going forward. Our partnership with Cisco is one that was built on trust over a long period of time. This has enabled us to work together to be able to provide the solutions that our customers need to drive their organizations forward. The value we add as a reseller is being able to work closer with our customers, understand them, and get intimate with their organizations. That enables us to offer them the right solutions that will help them achieve their goals.

Vulnerability And Compliance Manager at a insurance company with 5,001-10,000 employees

Unified vulnerability view has improved risk-based decisions but reporting still needs work

One of the main issues with Nucleus Security is its lack of reporting capability. The user interface resembles an early 2000s application style, and although its speed is decent, it could be improved as more data is ingested. The overall appearance and feel need work, especially compared to modern applications from Rapid7, Qualys, and Tenable, which have more engaging user interfaces. The reporting capability is severely lacking; not being able to filter to granularity or have custom built queries is an annoyance that needs an overhaul. Additionally, there are bugs that have not been resolved, such as when you create a report and remove an asset, the asset still appears in the report despite not being present in the system anymore, leading to issues that need to be addressed quickly. Nucleus Security can become a difficult investment because I already have a vulnerability management solution, and I question where Nucleus Security fits with its licensing model. While I acknowledge automation has been described, it would be amazing to control the entire vulnerability management workflow from Nucleus Security without needing to log onto other systems. Having controls or actions that can be sent from the console down to the scanner for rescans would be beneficial. If Nucleus Security is going down this path, it should ensure that it becomes a one-stop shop for vulnerability management across multiple applications.

"Customer support with Qualys TotalCloud needs a little improvement with the response times."

More Qualys TotalCloud cons

"If they could make the Cisco Umbrella piece a little bit more advanced or easier to manage, that would help. We use it for filtering and when you compare it to a normal content filter, it lacks some functionality."

"I'm not sure that I would call it a bug, but sometimes the solution is a little slow."

"They could put in more third-party [integrations]... also more playbooks, out-of-the-box, for automation [would be helpful]."

"I would rate this solution 7 out of 10. It's a great idea if it worked consistently, but it has to be way more mature than when I used it."

"what's missing right now is the multi-tenant capability."

"The documentation can be improved and the on-prem integration. The set of applications that it was integrated with wasn't comprehensive."

"It would be nice if they had a different pricing model. Most of our budget for projects goes towards Cisco."

"The front-end work controls the new algorithm and the firewall rules. The search feature of these rules could be improved."

More Cisco SecureX [EOL] cons

"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."

"One of the main issues with Nucleus Security is its lack of reporting capability."

"While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep."

"On a scale of one to ten, I would rate Nucleus Security overall a six."

Reviews from Real Users

Below are some reviews and helpful feedback written by Cisco SecureX users.

PeerSpot user Wouter H., Technical Team Lead Network & Security at Missing Piece BV, shares several reasons why he thinks the solution is fantastic. In his opinion, “SecureX takes all the separate pieces of security within your company, adds in intelligence from different sites and services on the internet, and makes them work together. If an email is received on a machine and malware is being executed, it can be put into lockdown mode. The fact that you can have a single solution that combines endpoint intelligence with email intelligence, firewalls, and publicly available intelligence is really helpful. Also, SecureX provides us with contextual awareness throughout our security ecosystem. Before SecureX, things that were not possible, or that would take days, now literally take seconds to find out.

Michal S., Infrastructure Engineer at a media company, says, “SecureX provides many measurements and has a really good dashboard. Working with it you are able to see things very clearly and you have every detail on a single display. That saves us money and time.” He also adds, “It brings all our data into a central point. It also shows us many data connections between many of our environments. SecureX gives you really good information about potential risks. You are able to find the source of a risk, a potential risk from a user or a machine.”

Blair A., Technology Director at Shawnee Heights USD #450, explains, "One of the most valuable features is the simplicity of deploying SecureX. It's very easy to do that and then you gain very detailed visibility into everything that's going on in your network and, obviously, at the device level. There's just a wealth of information that you can pull from all of these products that are part of SecureX. You know exactly if you have an issue or not."
