Pricing Advice

What users are saying about Device42 pricing:
  • "We pay $100,000 per year."
  • "On a yearly basis, our licensing is $10,000. However, our license is now nearly full with devices. We need the next bigger license with 5,000 devices, which will cost us $19,000. We pay for a set of licenses, a maximum number of devices, and a maximum number of IP addresses. We have the smallest amount of features, which is enough for us at this time."
  • "The problem with using other vendor, like BMC, is the pricing. The price is so horrible and nobody wants to pay this money."

Seeing how things are connected, which server ports are plugged into which network switches, helps with network troubleshooting

What is our primary use case?

Our primary use case is to track all of our IT information in one spot. So instead of using spreadsheets and other tools, it's consolidated here for us.

Pros and Cons

  • "The solution has some very good relational capabilities that show us how certain devices relate to each other and how some of our environment actually works together."
  • "The IP address tracking [is valuable]... We have a lot of different devices and some of them have many IP addresses, so keeping track of which ones are assigned where is very critical for putting new devices on the network and giving them new addresses. All of our devices are statically assigned, so if we don't keep good records then we could accidentally assign a duplicate, which would cause problems on the network."

    What other advice do I have?

    It's all pretty easy to use and you'll get out of it what you put into it. We try to make sure our information is accurate and up to date and we periodically do audit against the information to make sure it is current. The biggest advice I would give is to make sure you don't let your data get stale. Documentation is important. We've had internal problems where we've lost a hypervisor or our network has gone down and we haven't had access to it. Those scenarios have proven that we rely on the info and we need it. So having some kind of high-availability solution would be good for us at some…

    Continuous auto-discovery keeps infrastructure data up to date, enabling us to mitigate faster if a security patch is needed

    What is our primary use case?

    Our use case for Device42 is to capture all our infrastructure in a single tool. We need the ability to have that view of where our infrastructure is: servers, storage, network equipment, and applications sitting on top of servers. Our use case is to have that single pane for where all that is.

    Pros and Cons

    • "The auto-discovery is brilliant. You can have it scheduled to run on a regular basis, and the infrastructure is always getting updated within the platform. I would rate the asset discovery very highly. It's very comprehensive. It covers quite a lot of different methods for doing discovery and it supports a lot of different types of hardware as well."
    • "The dependency mapping can be quite slow sometimes, if you've got a lot of things connecting to services. It can be very slow to build up the map."

    What other advice do I have?

    The biggest lesson I would take from using the solution is to have an understanding of your infrastructure so you can better plan how you implement Device42. As with anything, there are obviously limitations as to what it can do. Sometimes there are certain politics within your business that may stop you from getting the most out of Device42. Also, although we didn't actually do so, I think it would be good to have a close relationship with the vendor of Device42, at the implementation stage. Our relationship has matured and been built post-implementation of Device42. It's going to be…

    Everything is in one place linked altogether

    What is our primary use case?

    The first use case is the most important. It is Application Dependency Mapping. We want to track what is dependent on what. We want to know when something goes down or a change is made. We are also trying to use it as a change management database for what hypervisor is in what rack which links over to what business application is running that uses what services and has what account. We have information scattered in a lot of different places. This seems to be a very nice solution for taking everything, integrating it together, and linking it all up. There seems to be a lot of automation… more »

    Pros and Cons

    • "Device42 has everything in one place and links it altogether. This helps when you need to figure out where things are going wrong, where things are happening, or how everything is linked together."
    • "The solution’s automatic IT asset discovery and inventory functionality functions pretty well. There could be some improvement if there were some automated scripts to get it off the ground. I know it takes a bit of effort to get all of various managed devices into one place. We have to go and change how they are managed and make sure they are all linking up correctly so they can be tracked in Device42. Some type of automated script for each to get over that initial activation."

    What other advice do I have?

    There are pros and cons to the solution’s agentless approach to asset discovery. Without agents, the benefit is that you don't have to manage an agent, update it, install it, and go through the application management on it. It's definitely easier from a longevity perspective. The con is that it takes a bit more configuration with higher activation to set up. If there were agents, it might be a bit simpler to deploy. Something that we are in the early stages of is the solution’s CMDB, ITAM, and DCIM features creating a single source of IT truth in our environment. It is in our roadmap plan and…

    Helps you understand how everything is connected in your environment

    What is our primary use case?

    Our goal for using the product is to be able to migrate apps to the cloud successfully. E.g., you can't move something if you don't know all the dependencies or all the bits and pieces that need to go with it. If you move something and forget, "Because it talks to this database," and no one realized, then it's going to fail. You will have downtime and have to move everything back. App dependency is the biggest part for us right now. That is the immediate need. I have been focused exclusively on bringing in data, connecting it and making sure all the servers and network devices are being… more »

    Pros and Cons

    • "The way the solution’s automatic IT asset discovery and inventory functionality works is you set up a discovery job, then you can schedule it to run. I schedule all of the runs daily at different times so nothing is interfering with anything else. It's nice to know that you can set up the scan, schedule it, and sit back. You can check them every day and make sure everything ran, making sure nothing had errors, then you're good to go. Anything new is going to automatically be discovered, which is nice. It takes some of the stress off because you don't have to know, "If this team opened new servers, we need make sure now it will automatically pick them up." It is one less thing to worry about. It gathers a lot of data points."
    • "Since I was focused on deploying connectors and getting all the servers to be scanned, one of the biggest pains was when a job would fail, then the output (logging) was poor. For example, "Why did it fail?" In these cases, you get a generic error. It doesn't point you in the right direction and tell you why you got the error, which is really annoying. There have been times I asked, "Is there somewhere I can see a better log as to why is this failing?" That would be a really nice improvement."

    What other advice do I have?

    The environment is a lot more complicated than I thought. It is like, "Wow, there are so many more servers, devices, and things talking to things." I have been in corporate enterprise environments for many years now, and this is the point of the app. I never really stopped to look at the big picture: "Wow, the environment is really complex." It's an eye-opener and makes you think about things differently. E.g., when you make a change to one thing, it helps you understand all the different things that could or could not be impacted. If you think small, then, "I will make this change to this one…

    Helps do full device-lifecycle tracking and automate VM deployment

    What is our primary use case?

    We use Device42 mostly for asset inventory because our compliance rules require us to know what devices we are using: the warranty for each device, when we install it, when we remove it — so full tracking of the device lifecycle. We use Device42 mostly for asset inventory, including physical pieces of hardware and virtual devices as well. We expected we would use a SaaS version but it was not possible, so we use the on-premise version. We have more than one instance of Device42. We have four implementations of it in our company. Each of them is dedicated to a single environment: government… more »

    Pros and Cons

    • "We use the automatic IT asset discovery for different things, like VMware discovery and SNMP discovery for network devices. It helps us to keep hardware information up to date in Device42, and the VMware discovery helps us to keep virtual device inventory up to date... We are sure to have 100 percent of our devices in Device42. Not more, not less."
    • "Device42 is a main part of our processes. We need reliability, not only in terms of the data but with the solution itself. It's really difficult when we have 10 minutes of Device42 downtime because none of our teams can work for those 10 minutes, and it's more time lost if there is longer downtime. An improvement would be to have a cluster implementation of Device42 to have high-availability and ensure that we don't have downtime in case of failure."

    What other advice do I have?

    The biggest lesson we have learned from using this solution is that if we want to have clear asset management, we need to have the same processes, policies, and rules in each part of our organization. If each part of the organization works only on its side, it's really difficult to reconcile asset management. That's why each technical team that owns devices has to share their processes and work in the same manner. When that is done, it's really easy to have good asset management. We don't use the solution's Application Dependency Mapping. In our organization, it's too difficult for a team to…

    Continuous discovery displays new racks after installation, but some devices are not discovered

    What is our primary use case?

    In the beginning, we were looking to use it as an IPAM device but we saw all the benefits in having control of the assets, the racks, and how the physical servers are connected to the switches. We set up our data center with all the racks inside and all the devices inside the racks. So at first, we used it for IPAM, but after that we constructed the building with the rooms and the racks. So IT inventory is the second purpose of this tool. We use it to track how VLANs and our different virtual devices are connected and to inventory VMware and Xen virtual machines. But the main purpose is IPAM… more »

    Pros and Cons

    • "The solution's agentless approach to asset discovery is very important for us because installing agents on physical or virtual devices is not easy in our company. We have to escalate these kinds of things to different levels of security. Not having to install agents makes it easy for us."
    • "While the automatic IT asset discovery is great, the first time using it can be confusing when you are configuring the SNMP. I don't remember for sure but I don't think it said "SNMP community," it said "password". The first time I used it I was thinking about communities but the tool said "password," and when you say "password" in SNMP you are thinking about SNMP version 3. This is the only thing that is confusing, although there were some devices that were not included in the discovery."

    What other advice do I have?

    Test it. You may discover that tools that you hadn't thought about. As I said, we tested it only for the IPAM, but we saw that we also needed the hardware inventory. If you do a PoC, you may discover that you need other features that are part of Device42. The biggest lesson I have learned from using this solution is to stop using Excel sheets. That was number-one. And the visibility that we have made available with Device42, to the rest of our company, has had a very positive impact on our team. In terms of the automated asset discovery, we have had to configure and customize some things…

    We know exactly where our comms rooms are, what they're called, and what's patched into them

    What is our primary use case?

    We mainly use it to keep an inventory of everything, because we've got 77 offices and data centers globally. We use it mainly to keep track of assets we have in cabinets and the like. Also, some of the other teams use it for the auto-discovery and license renewals. Device42 tells you when a license is about to expire on a server. I'm sure there are a lot more uses but because I work in data center management, and from my side we mainly use it just for inventory. We're aware of exactly what we have, where it is, whether it's powered on it, whether it's in service, etc.

    Pros and Cons

    • "The continuous asset discovery is good because it means not having to manually input all the small data, such as IP addresses, leases, etc. It helps and saves us a lot of time."
    • "If I want to delete an asset from a cabinet it does take a while. And if I'm doing it in bulk — say, for example, if we have one cabinet that has 20 servers in — if I want to remove all 20 servers, I have to do them individually, which is a bit time-consuming. If there were a way that I could just bulk-remove everything from there, that would definitely save some time."

    What other advice do I have?

    Be very thorough with it. Make sure you put in everything you need to put in and make sure the auto-discover function works properly. The biggest lesson I've learned from using Device42 is the importance of keeping it up to date and taking out redundant stuff. Especially with the auto-discover, if I've decommissioned something but not taken it out of Device42, the auto-discover will still think something is there and that creates a bit of a problem for us internally. In my department, there are only two of us in data center management. But the whole network team use Device42, as do the whole…

    We are making it our single point of truth; no other tools needed

    What is our primary use case?

    Device42 will be the single point of truth for our network, service, and device documentation. The first step is to put all data inside with the goal to discover all things automatically. We do have a few things we must fill in manually. The second step is to use this data and create automation. When we can do this, it will be a big step towards successfully automating our processes overall. Processes can be in connection with the driver ticketing system, the installation of new virtual machines in new containers to grab data automatically to ask the system what is free, determining what we… more »

    Pros and Cons

    • "A big plus for Device42 was the auto-discovery. With it, we have updated devices, updated systems, and up-to-date systems."
    • "When servers have two network adapters, automatically discovered will be only one network card because the other one is a backup. Device42 has some problems to find the other connection."

    What other advice do I have?

    Overall, I am happy with tool because we have a big infrastructure across the world with a lot of different devices. We have a lot of service, virtualization, hardware machines, and network devices. You can't find a perfect tool for all devices in this world. You must find something in the middle, and Device42 is a good tool for this. The agentless approach is a good feature. It didn't work for me. I was happier with the agent, as I had immediate good results. There are only a few people still manually creating tools because we have no option for these specialty devices. For these specialty…
