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 uncovered unauthorized devices and now protects client networks
I think the best feature of Armis Centrix for OT/IoT Security is that it ensures only the authorized devices and users are authorized to prevent any potential breaches. I think that clear definition is very essential for a lot of networks because it helps us understand who should be there and who shouldn't be. For our clientele, we were able to discover a lot of unauthorized devices that were on their network. This first of all helped them remove a lot of potential security breaches and cleared the bandwidth of the network as well. I think this has been one of the biggest cases that we have found. For most of the clients where we have deployed it, this has always been a common occurrence because a lot of people enter the network and then you don't know who is there, who has the access, and so on. I think this is the very reason I said what I said earlier.
