Akhilesh Mishra - PeerSpot reviewer
Technical Lead Pre-Sales at M.TECH Solutions India Pvt. Ltd.
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 view has improved risk-based decisions but reporting still needs work
One of the main issues with Nucleus Security is its lack of reporting capability. The user interface resembles an early 2000s application style, and although its speed is decent, it could be improved as more data is ingested. The overall appearance and feel need work, especially compared to modern applications from Rapid7, Qualys, and Tenable, which have more engaging user interfaces. The reporting capability is severely lacking; not being able to filter to granularity or have custom built queries is an annoyance that needs an overhaul. Additionally, there are bugs that have not been resolved, such as when you create a report and remove an asset, the asset still appears in the report despite not being present in the system anymore, leading to issues that need to be addressed quickly. Nucleus Security can become a difficult investment because I already have a vulnerability management solution, and I question where Nucleus Security fits with its licensing model. While I acknowledge automation has been described, it would be amazing to control the entire vulnerability management workflow from Nucleus Security without needing to log onto other systems. Having controls or actions that can be sent from the console down to the scanner for rescans would be beneficial. If Nucleus Security is going down this path, it should ensure that it becomes a one-stop shop for vulnerability management across multiple applications.
