Identity management has streamlined user lifecycle and now guarantees first-day access
The best features Armis offers include the interaction with my manager in Brazil, whose first name is Rui, and who provided a lot of experience, especially Horácio, who used to work for Microsoft. Horácio helped with issues related to Active Directory and provided ideas on how to best integrate the solutions. The aspect of Armis solution that stood out to me was its flexibility to integrate different applications. The collaboration of the team is really important and key for the project to go well and bring the results the customer is looking for. The solution has the necessary resources and connectors that have built many of the rules needed for integration, regardless of whether the application is an Active Directory, an LDAP directory, a database, or even a specific solution such as SAP. It is also flexible enough to build the business rules that apply specifically to that customer. Armis has positively impacted my organization and my client's organization by ensuring that on day one, new users had all the access they needed to work for the applications that were integrated. Additionally, if a user was dismissed from the company, they would lose all access to the integrated applications because Active Directory, which was key for user authentication, would disable their account. I do not recall any specific statistics regarding measurable results, but there was positive feedback from managers concerning the process during the time I was there.

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.

Cons

"In terms of stability, Armis is not completely stable, as sometimes incidents may occur."
"Like any IT tool, continuous learning and improvement are essential for the solution."
"After implementing Armis, an organization experiences it as an add-on. Without asset visibility or vulnerability prioritization, it becomes a useless product."
"There are occasional issues with some built-in integrations that require troubleshooting, particularly with DHCP integration. Developing additional integrations would be beneficial."
"The vulnerability assessment for Windows is not that great. It misses out on a lot of vulnerabilities."
"We face issues during implementation."
"There isn't anything specific that needs improvement."
"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."
"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."
"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 primary area that needs improvement is compatibility with the latest IoT technologies."
"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."
"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."
"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."
