9 Free Cyber Security Labs.
SOC, Pen Test, SASE — All in Browser.

Yes — fully free, no payment, no card details, no login, no time limit. The 9 simulators are open-source on the Networkers Home GitHub organisation (github.com/NETWORKERS-HOME-123) and hosted on Networkers Home subdomains. They run in the browser. No install, no virtual machine licence, no vendor evaluation key.

CompTIA Security+ and CEH (Cyber Attack & Defense Simulator + Network Packet Flow), SOC analyst readiness (Attack & Defense + Cisco ISE + Zscaler), SASE / ZDTA (Zscaler ZIA), PCNSA / PCNSE (Palo Alto PAN-OS), NSE 4 / NSE 7 (Fortinet FortiGate), and CCNP Security / NAC (Cisco ISE). Cumulative coverage runs to 300+ distinct lab scenarios across the 9 simulators.

Partially. The Cyber Attack & Defense Simulator covers ransomware, DDoS, insider-threat, and phishing scenarios with response playbooks — that's the bulk of SOC L1 readiness. Add Cisco ISE for identity-and-access fundamentals and Zscaler ZIA for SASE / URL filtering / DLP context. The gap they don't fill: real SIEM tuning at production scale (Splunk, ELK, QRadar log volume), and EDR/XDR vendor-specific workflows (CrowdStrike, SentinelOne). For those, supplement with vendor sandboxes or — Bangalore-based students — the institute's 8-month Cloud Security & Cybersecurity programme runs real SOC simulations on production logs.

Vendor demos are time-limited (Splunk Cloud trial: 14–30 days; CrowdStrike: sales-gated; Zscaler: enterprise-only) and require corporate email registration. These simulators are forever-free, no email required, no time limit, hosted on Networkers Home infrastructure. The trade-off: simulators model concepts and workflows but don't process real production-scale data. They're for learning, not for actual incident response. The combination most students use: simulators for the first 4–6 months of skill building, vendor sandboxes for the final 4–8 weeks before certification or interviews.

The institute's stated position: the cyber-security skill gap in India is bottlenecked by lab access, not interest. Students self-studying for SOC analyst, Security+, CEH, or PCNSE roles need hundreds of hours of hands-on practice — and pay-walled vendor labs ration that practice by budget. Releasing the simulators as a public good removes the rationing. It also signals the institute's actual quality posture: you don't give away the lab if the lab is the value proposition. The institute charges for the 8-month placement-guarantee programme (real hardware, faculty, paid internship, contractual placement) — not for the practice rail.

No. The labs are public — anyone with a browser can use them, indefinitely, without payment or registration. They're available 24×7 from any browser worldwide. The institute does run an 8-month Cloud Security & Cybersecurity placement-guarantee programme in Bangalore (₹96,000 all-inclusive) where students train on real production hardware in addition to these simulators — but enrolment is fully optional and not required to access any lab.

Yes — every simulator URL on this page is verified at build time. Before this page deploys, an automated check runs HTTP GET against each of the 9 simulator subdomains; if any returns anything other than 200, the page does not deploy. The status indicators in the verification section below are accurate for the current deployment. Linkrot is the standard failure mode for free-resource pages; the build-time check exists specifically to prevent it.

Yes — every simulator is open-source on github.com/NETWORKERS-HOME-123, with a permissive licence. Fork, run locally, modify, contribute pull requests, or embed in your own learning platform. Each simulator has its own repo with full source code. Issue reports filed against any repo are visible publicly; response time is typically 1–2 weeks.
