Full-spectrum adversary emulation mimicking advanced persistent threats (APTs) targeting Active Directory and zero-trust boundaries.
Explore Threat Emulation →Custom capture-the-flag battlegrounds with dynamic scoring, anti-cheat isolation, and multi-team scoreboards for corporate drills.
Deploy CTF Tournament →Live defensive triage environment with Wazuh SIEM, real-time PCAP traffic analysis, and detection engineering challenges.
Launch Defense Sandbox →
Spawn an isolated target machine with a single click. No manual installs — access via OpenVPN or stream an interactive Kali desktop directly inside your browser.
Navigate tactical cyber warfare milestones from defensive SOC telemetry to full Active Directory domain privilege escalation.
Triage real adversary telemetry inside Wazuh & Splunk. Detect Kerberoasting, beaconing & lateral movement.
Perform deep volatile RAM inspection using Volatility 3 to uncover process hollowing, injected DLLs, and encrypted C2 strings.
Enumerate domain trusts, abuse Kerberos delegation, forge Golden Tickets, and execute DCSync against CORP.LOCAL DC.
Chain multi-tier network pivots, bypass modern EDR ring3 hooks, escalate to root, and capture the elusive master flag.
Live standalone vulnerable systems simulating realistic real-world security vulnerabilities and misconfigurations.
Enterprise Active Directory domain controller featuring AS-REP roasting, unconstrained Kerberos delegation, and BloodHound attack paths.

Hear what active penetration testers and CTF players say about the CodexSec Labs experience.
"The Sentinel-DC01 Active Directory lab is easily the most realistic target environment I've ever encountered. Bypassing modern defenses and learning DCSync hands-on was pure gold."
"The AI target sandbox with prompt injection scenarios felt like tearing apart a live production assistant. Zero setup or VPN delays — it worked right in my browser."
"Having on-demand resets and realistic SIEM integration makes CodexSec Labs miles ahead of theoretical platforms. It is built strictly for practitioners."
