UnderDefense

Founded in 2017 in Lviv, Ukraine, by Nazar Tymoshyk and former students, UnderDefense started as a penetration testing outfit before evolving into a global Managed security powerhouse. Their homegrown UnderDefense MAXI platform—freemium and platform-first since its 2023 launch—centralizes 24/7 MDR, SIEM, vulnerability scanning, compliance automation, and incident context. Backed by a team of ~120 certified experts, they protect over 65K endpoints via a remote-work model based in Ukraine, Poland, and the U.S., earning recognition in Gartner’s 2023 Market Guide for Ukrainian IT and Clutch’s Top 2025 Cybersecurity listing.

Their hallmark? Human-led, rapid detection and response—boasting SLA responses under 20 minutes and MTTC slashed by 2 days versus major rivals like CrowdStrike OverWatch.
