"runZero is the first and only service capable of real-time asset discovery rather than simple asset inventory that is built once and then never maintained. runZero has helped solve a vexing problem for us and improved our security posture significantly almost immediately after deployment. It is incredibly fast and gathers a wealth of information about your assets without needing to add credentials. You can’t protect what you don’t know and for the first time we actually know and are informed in real-time when something changes that could expose us to risk."

"It provides a rich insight into your environment with very little effort. It’s profiling capabilities are great considering there is no agent on the endpoint. It’s simple to configure and manage. The support team is very responsive and the product development team turn around feature requests in very short time frame."

"The first step was to do a complete inventory, and by that, I mean an actual real scanning-based verification of what was on our network. I knew we did not formally use SolarWinds Orion internally; however, that does not mean someone could be running it informally in a lab. We are using runZero for internal scanning. It is fast and accurate."

"Simple, focused, flexible, no brainer. This product is a no brainer. If you need to scan your environment, this is just better than anything else. It doesnt try to solve other problems (vuln. mgmt for expl) and is easy to use and integrate. runZero fill a gap most large scale operations have: identify assets. Running the tool is super easy and give you immediate value."

"What is the CSC’s control number 1? The inventory of systems is the CSC control number one. You can’t protect what you don’t know you have in your environment. This product solves that problem and more… We were up and collecting data within minutes! This product gave us visibility into devices/systems on our network and helped me discover misconfigurations and out of date operating systems."

"runZero is amazing because it was able to map out the entire network without any credentials, and is even more accurate than my NAC solution. It identified a BACnet device from way back when the facility was built - about 20 years ago. runZero replaced several of my tools, including nmap, Wireshark and Angry IP. Now, when we install new equipment, I can easily tell what IP spaces are available. As we’re moving to a zero-trust model, knowing what’s on our network is critical."

"Love runZero!!! The responsiveness of the runZero team and their customer support is incredible! The team follows up on the issues incredibly fast. They listen to customer’s wants and desires and, when such wants make sense, implement them into the product. I am more than satisfied with the company and with the product. Easy to implement, easy to use, very fast, very helpful."

"If it’s connected, runZero WILL find it. runZero augments and validates your system inventory in ways previously not possible with this level of ease. I can quickly look at hosts, OS versions, services, etc and cross-reference with known good inventory to find problems. As an example, I found a printer with an extremely old firmware that had gone un-patched for years. I like the ease of deployment and the versatility of the agents. I’m running on multiple operating systems and hardware platforms and they all work amazing. I also love the WiFi Scanning for WiFi-enabled agents, and the screen capture function for anything that responds to HTTP requests."

"runZero is like nmap on steroids; actionable intelligence fed daily. I used runZero for several client networks as a test and additional information compared to my normal nmap / Nessus / etc scans. Honestly, even the betas of runZero gave me more actionable intelligence than the others. Today’s networks often have single factor authentication services exposed remotely, even when they loudly proclaim that they’ve moved to 2FA. Finding and categorizing services (Remote Desktop Gateway via HTTPS, OpenVPN Appliance, Exchange, etc.) was really powerful and impressive especially, for quick review of larger environments. I’m deeply impressed by the depth of protocol knowledge displayed and made available with runZero. Correlating assets that change IP addresses automatically, loads of support for SNMP… the list goes on and on."

"We’ve been incredibly impressed with what runZero is able to deliver considering how easy it is deploy and how little resources it requires. Our organization has around 10,000 assets across 50 locations and the complete configuration and deployment took about one day of work. One other item to mention is how incredible support is. We’ve had a few questions and issues along the way and support has been the most responsive I’ve ever experienced. We regularly get not only responses but actual deployed product updates quicker than it sometimes takes to get a response from my own staff. I’m talking hours and in some cases minutes."

In our use case, it provides us with quick discovery of all assets in our internal network and shows us running services based on common open ports. It is much quicker than other tools I’ve used and the fact that it is agentless is also a huge pro."

Really great value, puts competitors ROI figures to shame."
