Start with blue-team cybersecurity - then grow into coding, AI, exam prep and study tools, all with the same XP, ranks and gamified progression.
Hands-on blue-team labs, SOC investigations and CTF challenges with an animated attack replay.
Guided, project-based tracks that teach real programming - from fundamentals to shipping.
Here's a slice of a threat hunt. Read the connection log, spot the command-and-control beacon, and submit the IP - exactly like a real lab task.
$ zeek-cut id.orig_h id.resp_h id.resp_p < conn.log
10.10.14.23 → 93.184.216.34 :443 ssl
10.10.14.10 → 142.250.72.14 :80 http
10.10.14.23 → 45.77.122.9 :443 ssl (x15, 60s interval)
10.10.20.5 → 151.101.1.140 :443 ssl
Which IP is the C2 beacon?
Hint: one host beacons on a fixed interval.
$ zeek-cut id.orig_h id.resp_h service < conn.log
10.10.14.23 → 45.77.122.9 ssl (beacon x15, 60s)
10.10.14.10 → 142.250.72.14 http
Most platforms teach you to attack. CyberNexura trains you to detect, investigate, and respond - the way a real SOC works.
Download actual PCAPs, EVTX, memory dumps and phishing emails and analyze them in Wireshark, Zeek, or your own SIEM - not a locked-in browser VM.
Purpose-built for defenders across SOC, DFIR, threat hunting and IR - not an afterthought bolted onto an offense platform.
Nothing to boot, no cloud machine to wait on. Pull the evidence and start investigating anywhere - even air-gapped.
Findings are checked server-side, points scale with difficulty, and the full analyst writeup unlocks the moment you finish.
Grab the real artifacts - PCAPs, event logs, memory images, phishing emails - and open them in your own tools.
Work the scenario, answer the graded questions, and get instant feedback. Answers are checked server-side.
Score points scaled by difficulty, unlock the analyst writeup, and rise up the leaderboard.
Real scenarios you can start right now.
Every solved task earns points. Progress from your first login to the top of the SOC.
Every analyst has a war story. Soon you'll be able to publish your own labs and writeups, so CyberNexura becomes an ever-growing bank of real-world defensive scenarios - authored by defenders, for defenders.
The platform grows one facet at a time - defense first, then AI-assisted analysis, then offense.
No. Download the evidence files and analyze them in your own tools - Wireshark, Zeek, a SIEM, whatever you use. Nothing to boot, works even offline.
Both. Start with the First Shift onboarding path, then climb from Easy labs all the way to the advanced Pro Range.
Findings are checked server-side and points scale with difficulty. The full analyst writeup unlocks the moment you complete a lab.
Yes - core labs, leaderboards, seasons and learning paths are free forever. Pro unlocks the advanced Pro Range and upcoming certifications.
