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.

Centralized security testing has improved vulnerability remediation and compliance reporting
I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

Quotes from Members

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

Pros

"Armis saves time by automating asset inventory management, allowing enterprises to quickly strategize by understanding their assets and exposures."
"The most valuable feature of the solution is asset tracking."
"The initial setup and deployment were simple."
"Armis is very easy to implement due to its agentless design and offers a granular level of visibility for all assets in the network."
"Armis is a straightforward and user-friendly solution."
"Armis is very easy to implement due to its agentless design and offers a granular level of visibility for all assets in the network."
"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 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."
"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."
"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."
 

Cons

"We face difficulties in integrating the product with ticketing tools like ServiceNow."
"The solution's vulnerability testing could be improved."
"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."
"We have faced issues with the tool's stability."
"Armis doesn't have a back intel feature."
"We face issues during implementation."
"After implementing Armis, an organization experiences it as an add-on. Without asset visibility or vulnerability prioritization, it becomes a useless product."
"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."
