1stProtect.ai vs Linux Expl0rer: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
1stProtect.ai is a commercial detection engineering tool by 1stProtect.ai. Linux Expl0rer is a free detection engineering tool. Compare features, ratings, integrations, and community reviews side by side to find the best detection engineering fit for your security stack.
CST VerdictBased on our analysis of core features, integrations, here is our conclusion:
Incident responders and forensics teams investigating Linux breach timelines will get the most from Linux Expl0rer because it runs live on compromised hosts without requiring agent pre-deployment, letting you pull memory dumps and process trees while attackers are still present. The tool ships with YARA scanning built in and costs nothing, removing friction for teams that need fast triage across dozens of endpoints after an alert fires. Skip this if your organization needs post-mortem analysis only or requires commercial support contracts; Linux Expl0rer is a responder's tactical knife, not a platform.
