Damn Vulnerable Linux (DVL) is a free cyber range training tool. HackSys Extreme Vulnerable Driver (HEVD) is a free cyber range training tool. Compare features, ratings, integrations, and community reviews side by side to find the best cyber range training fit for your security stack.
CST VerdictBased on our analysis of available product data, here is our conclusion:
Security engineers and students building Linux exploitation skills need Damn Vulnerable Linux because it gives you a sandbox where every vulnerability is deliberately exposed and documented, eliminating the guesswork of "is this actually exploitable or am I missing something." The OS includes over 20 intentional weaknesses across privilege escalation, web apps, and local services, each mapped to real CVEs so your training translates to actual threat hunting. Skip this if your team needs a cloud-native range or role-based labs; DVL is bare-metal Linux practice, nothing more.
HackSys Extreme Vulnerable Driver (HEVD)
Kernel security researchers and red teamers building Windows exploitation skills need HackSys Extreme Vulnerable Driver; it's free and has 2,966 GitHub stars because it deliberately packs multiple vulnerability classes into a single driver, letting you practice the full exploit chain without hunting through real-world code. The tool isolates kernel vulnerabilities at teaching scale, so you're not reverse-engineering obfuscated production drivers or waiting for lab access. Skip this if your team needs a sandbox for zero-day triage or incident response simulation; HEVD is purely an offensive learning tool, not a defensive testing platform.
