Device42 users seek enhanced interface, integration, pricing, with improved widgets, graphics, navigation, automation, and support efficiency.

Qualys VMDR needs improved support, efficient reporting, UI, asset notifications, reduced tool dependency, better pricing, and comprehensive resources.

Likod Andrew

Financial Specialist at Wells Fargo

I foresee areas of improvement for the agent-less solution, which could be very useful for those organizations that might not allow configuring an agent in their source machines for workload discovery.

Manmohan Rao

Associate Vice President at Hitachi Systems India Private Limited

From an ITSM and ticketing perspective, I would say if there were integrations available, that would have really been better because a lot of times what we end up seeing or leveraging is ServiceNow because they have that native or out of the box capability, and even Freshservice has that capability out of the box.

Granular discovery has ensured confident workload migration and optimized cloud move group planning

Device42 offers the best features for workload assessment, particularly useful for cloud-to-cloud workload or on-premise data center workload, especially when planning for workload migration to the public cloud. For application and infrastructure discovery, Device42 has enabled me to know the number of machines running in the on-premise environment and has managed to capture complete utilization metrics or trends of their utilization. This has benefited me in right-sizing systems for my public cloud total cost of ownership (TCO) planning, providing me granularity to right-size these systems while planning a migration to the public cloud. Device42 has positively impacted my organization by providing granularity toward application discovery compared to other assessment tools, which is a differentiator since none of the other tools provide such granularity, leading to better decision-making for my migration to the public cloud. Device42 has improved my migration projects by providing granularity around system dependencies that gave me confidence knowing which systems communicate with each other parked in a particular move group. My move group planning became so robust that I am not leaving any system behind in the on-premise data center from my planning, which saves a lot of time and effort, leading to cost optimization—a value addition.

Continuous risk-based monitoring has strengthened incident response and vulnerability prioritization

I haven't explored Qualys VMDR's vulnerability lifecycle automation yet. One of my analysts mentioned that queries lack grouping operators in Qualys VMDR. From my experience, I would appreciate improvements in the query options in Qualys VMDR, specifically in the query-building process where I would need more features and operators. Additionally, we have been facing issues with Qualys on the cloud level. We cannot download the configuration profile from the cloud agent, and it is showing a pending action for download. During 2025, we noticed outages of Qualys a couple of times. I want to mention that there is an issue with receiving timely RCA deliveries. While this is not necessarily about the tool, it relates to support. The support has not been very responsive, and we are receiving RCAs a little delayed whenever we raise support cases or communicate with the TAMs. Additionally, the UI has a slight latency, which I and my team have experienced. They have also reported this latency issue when navigating through different pages.
