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 data has transformed risk prioritization and optimized remediation effort
The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms. It is helping quite a lot to unify all of that. It also offers good prioritization based on the EPSS or the CVSS score, as well as different other factors including Mandiant threat intelligence and similar aspects. It helps bring it all into one big picture instead of different silos of vulnerabilities. The integrations make my job easier because I can connect my other tools, which is the most important part of this tool to bring in all the vulnerabilities from the different other tools. The prioritization changed it from chasing vulnerabilities or pushing colleagues to patch vulnerabilities to providing colleagues with their vulnerabilities and requesting remediation and patching. Nucleus Security positively impacts my organization by bringing awareness to vulnerability management since we can actually determine how many vulnerabilities we have and how critical the risk is, or we can quantify the risk overall for the company.
