Comprehensive visibility has transformed how I secure and prioritize risks across connected devices
The best features Armis offers include vulnerability management for OT and IoT devices, providing risk prioritization, and offering protection across all connected assets. Armis cyber exposure management is very good as it provides continuous visibility, risk prioritization, and protection across all connected assets. Armis has positively impacted my organization by providing asset discovery for both OT and IoT, as well as threat visibility for OT and IoT devices along with vulnerability information, including the CVE number so that I can fix the threat on OT and IoT devices. Most of the time, focus is on IT devices and attention is not paid to OT and IoT. Armis facilitates focus on OT and IoT as well, closing the gap that often exists. Armis makes life easier for customers by providing visibility of OT and IoT, as well as threat visibility. Armis has a user-friendly interface, is very useful for customers, provides quality support, and has a global presence allowing easy access for both customers and Armis representatives. The console is user-friendly. Armis handles compliance requirements in my industry very well and is useful.

Improved radiation safety and compliance has supported patient care but daily workflows still need refinement
I think it can be improved by making it more practical, integrated, and easier for teams to apply in real-world workflow from a healthcare perspective. The main improvements I can see right now are better user training with real-case scenarios rather than only theory, and clear and simple protocols for day-to-day operations. Strong integration between safety compliance and documentation systems would help significantly in practice for the healthcare field, which is a niche field. The biggest gain would come from making security processes easier to follow consistently, especially in busy environments where teams need to be aware of clarity and really need to rely on the documentation they are using.I chose a rating of seven because it offers strong value in safety, risk reduction, and compliance, especially in healthcare. However, there is still room for improvement in usability and day-to-day integration. Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow.

Quotes from Members

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

Pros

"Armis is a straightforward and user-friendly solution."
"Armis is easy to use."
"The technology is good."
"Armis is very easy to implement due to its agentless design and offers a granular level of visibility for all assets in the network."
"The initial setup and deployment were simple."
"Armis transforms cybersecurity from a cost center into a business performance driver, delivering quantifiable ROI through reduced risk, operational efficiency, and compliance readiness for board-level discussions."
"It determines which assets and devices are at risk, alerts you if there's a risk, and categorizes all assets, including personal computers, mobile phones, servers, televisions, cars, and video game consoles."
"Armis has reduced the cost of employment because before, I had to take all the logs, and the logs required so many more employees, but currently, one employee is handling everything, saving the cost of four employees."
"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."
 

Cons

"We have faced issues with the tool's stability."
"There are occasional issues with some built-in integrations that require troubleshooting, particularly with DHCP integration. Developing additional integrations would be beneficial."
"There isn't anything specific that needs improvement."
"We face difficulties in integrating the product with ticketing tools like ServiceNow."
"Armis doesn't have a back intel feature."
"My experience with Armis has been positive, especially around asset visibility, unmanaged device monitoring, and risk intelligence. However, there are a few areas for improvement."
"Like any IT tool, continuous learning and improvement are essential for the solution."
"In terms of stability, Armis is not completely stable, as sometimes incidents may occur."
"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
