About 5iron

5iron Active Cyber Defense solutions provide comprehensive detection and response, 24x7x365. We actively respond to events as they occur, requiring less bandwidth from our clients and taking the action needed to eliminate the threat before it causes disruption to client business or data. This approach enabled 5iron to be named to the 2022 Inc. 5000 list of fastest-growing private companies in the US.

5iron redefines industry expectations by taking an active role in the protection of our clients. Delivering 24x7x365 “eyes on” cybersecurity defense solutions, effectively minimizes cyber risk inside these organizations. Our active cyber defense solutions leverage years of information security experience to protect critical network infrastructure from the growing number of cyber threats.

5iron’s Security Operations Center (SOC) is located in Franklin, Tennessee and all security operations are run from this facility. 5iron does not use a Virtual SOC in which Security Analysts work from home or another remote location which can slow response times and affect client security. Our goal is more than notification—Our goal is response and resolution.
