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.

Unified vulnerability workflows have transformed how our teams prioritize and resolve critical risks
While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep. When first setting up complex, multi-layered automation rules and asset groupings, the interface can feel a little overwhelming. Having more intuitive step-by-step visualized wizards or guided templates for building complex triage workflows would make the onboarding process much smoother for new team members. Dashboard customization and reporting would definitely be on my wish list. While the default dashboards are great for a general overview, it can take a bit of manual tweaking when building highly tailored workspace views for different engineering groups. Having a more flexible drag-and-drop widget system where individual teams can prioritize exactly what metrics they see first on their layout would be a huge quality of life update. On the reporting side, the data it generates is solid, but I would like to see more granular control over formatting within the platform itself. Sometimes leadership wants data tailored in very specific ways, and currently, we occasionally have to export the data and clean it up externally to meet those exact visual preferences.

Quotes from Members

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

Pros

"Real-time asset monitoring in Armis helps with network operations, especially in comparison to Nozomi."
"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."
"Armis has positively impacted my organization by helping me identify vulnerabilities more effectively, especially on assets that I did not know existed on the network."
"The most valuable feature of the solution is asset tracking."
"Armis saves time by automating asset inventory management, allowing enterprises to quickly strategize by understanding their assets and exposures."
"I find the most valuable features of Armis to be its focus on IT, OT security, and medical device security."
"The technology is good."
"Nucleus Security has fundamentally changed how we manage our vulnerability lifecycle and made our entire incident response process much more proactive, organized, and reliable."
"The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms."
 

Cons

"The solution's vulnerability testing could be improved."
"After implementing Armis, an organization experiences it as an add-on. Without asset visibility or vulnerability prioritization, it becomes a useless product."
"We face difficulties in integrating the product with ticketing tools like ServiceNow."
"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."
"There are occasional issues with some built-in integrations that require troubleshooting, particularly with DHCP integration. Developing additional integrations would be beneficial."
"Armis doesn't have a back intel feature."
"Armis could improve its geographic spread and marketing campaigns across regions."
"We face issues during implementation."
"While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep."
"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."
