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.

Security monitoring has become proactive and threat hunting is now faster and more precise
The best features of Microsoft Defender for IoT are that it is easy to find where the intruder is and easy to capture and hunt intruders. When I need to send a full scan for a device, it is straightforward. I have worked with Symantec, which is an antivirus, and McAfee, where I send full scans in a similar way to how I do it in Azure Defender, and it is equally easy. I can take actions with the device, such as disconnecting it, turning it off, or sending an alarm. The integration with Azure Defender and Azure Sentinel is seamless because they are from the same company. They capture intruders, viruses, worms, and everything else easily, and I can fix problems quickly. I use the network visibility features daily to manage connected assets. Currently, I am closing a case with Mutual Asesorías where they have a computer with intruders attempting to force brute capture the password. I can see how the intruder tried to do this, and my work involves closing the IP origin in this case.

Quotes from Members

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

Pros

"The tool is user-friendly and helps to detect vulnerabilities."
"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."
"The most valuable feature of the solution is asset tracking."
"Armis is easy to use."
"The initial setup and deployment were simple."
"I find the most valuable features of Armis to be its focus on IT, OT security, and medical device security."
"Real-time asset monitoring in Armis helps with network operations, especially in comparison to Nozomi."
"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."
"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."
"The graphics and analysis in Microsoft Defender for IoT are very representative."
"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."
"As a cybersecurity consultant, the best part of Microsoft Defender for IoT is the capability to integrate with other tools such as Microsoft Sentinel and receive real-time alerts from the product."
"The best features of Microsoft Defender for IoT are that it is easy to find where the intruder is and easy to capture and hunt intruders."
"Some advantages of Microsoft Defender for IoT are that it's easy to install on any OS, and you can create any custom use cases easily."
"Mainly, it is manageable and integrates with other Microsoft products, which is crucial for me."
 

Cons

"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 isn't anything specific that needs improvement."
"We face issues during implementation."
"In terms of stability, Armis is not completely stable, as sometimes incidents may occur."
"There are occasional issues with some built-in integrations that require troubleshooting, particularly with DHCP integration. Developing additional integrations would be beneficial."
"The OpenText solution we used had to improve its development in relation to cloud environments. They have started to offer a version that works on the cloud, but they are really behind in that aspect today."
"Like any IT tool, continuous learning and improvement are essential for the solution."
"The solution's vulnerability testing could be improved."
"Microsoft Defender for IoT is not scalable. If you want to monitor another industrial network, you need an additional server, making it less scalable."
"The only improvement I see is that some detection explanations are vaguely provided by Microsoft, resulting in generic IoT detections that alert me to an issue yet don't specify what's wrong."
"The primary area that needs improvement is compatibility with the latest IoT technologies."
"Customer service and support from Microsoft are costly. The execution by engineers is expensive, and the service is neither free nor toll-free, making it less accessible for customers."
"The documentation for Microsoft Defender for IoT is lacking. There are no clear steps or guidance, and updates are frequent, which adds to the confusion."
"There are a few limitations with Microsoft Defender for IoT. We raised concerns with the product team because they don't capture all the information regarding command execution or processes executed on certain endpoints."
