§01Practice like the exam. Build like the job.
01 / CERT LAB

Graded hands-on labs

Write real configs against 41 challenges across 8 certification tracks. Each is auto-graded on the exam objectives and audited for security, with teaching explanations on every miss, progressive hints and a reference solution.

02 / READINESS

Know when you’re ready

A free, per-certification exam-readiness score that climbs as you pass challenges — so you can see exactly how close you are. Pro adds a timed exam simulation that mirrors the real thing and tracks your best score.

03 / GENERATE

Multi-vendor engine

Production-grade IPsec, SSL VPN, BGP, OSPF, NAT, firewall and hardening across all 11 vendors — deterministic, never improvised. The same configs that power Cert Lab grading.

04 / TRANSLATE

Cross-vendor translator

Paste a config from one platform and get the equivalent on another — interface naming, addresses, policies and crypto mapped across, with comments where there’s no clean 1:1. Built for migrations and multi-vendor shops.

05 / VALIDATE

Security audit, graded

Every config is scored A–F against best practice. Weak crypto, plaintext admin, permissive any/any rules and missing logging are flagged with severity — the same engine that grades your labs.

06 / ASSIST

Senior engineer on call

A Pro AI assistant that reasons like a network engineer, plus a log analyzer that turns raw device logs into anomalies, likely root cause and concrete next steps.

§03Frequently asked questions

Elematron is a graded, hands-on lab platform for network certification — CCNA, Fortinet NSE4, Juniper JNCIA, Palo Alto PCNSA, Arista, Cisco NX-OS, ASA and MikroTik — with a free exam-readiness score, plus a multi-vendor config generator, cross-vendor translator and A–F security validator.

What is Elematron?

Elematron is a hands-on lab platform for network engineers and certification students. You write real configurations against graded challenges across CCNA, Fortinet NSE4, Juniper JNCIA, Palo Alto PCNSA, Arista, Cisco NX-OS, ASA and MikroTik — each scored on exam objectives and on security — and you track a per-certification exam-readiness score. It also includes a multi-vendor config generator, a cross-vendor translator and an A–F security validator.

What is Cert Lab?

Cert Lab is a graded, hands-on challenge system. Each challenge gives you a scenario; you write the configuration; it is auto-graded against the exam objectives and audited for security, with teaching explanations on anything you miss, progressive hints and a reference solution. There are 41 challenges across 8 certification tracks today, and the bank keeps growing.

How does the exam-readiness score work?

As you pass challenges, Elematron computes a per-track readiness percentage, weighted by difficulty, so you can see how close you are to exam-ready for CCNA, NSE4 and every other track — for free. Pro adds a timed exam simulation that mirrors the real thing and records your best score per track.

Which vendors and certification tracks are supported?

Tracks today: Cisco CCNA 200-301, Fortinet NSE4/FCP, Juniper JNCIA-Junos, Palo Alto PCNSA, Arista EOS, Cisco NX-OS, Cisco ASA and MikroTik MTCNA. The underlying config engine covers Fortinet, Cisco IOS/NX-OS/ASA, Juniper, Palo Alto, Arista, MikroTik and more — over 100 configuration use cases in total.

Is there a free plan?

Yes. The free tier includes your exam-readiness score, several graded Cert Lab challenges a day, a daily practice taster from the exhibit-based MCQ exam banks (CCNA, Fortinet NSE and more), three configs and one translation a day, all vendors, the A–F security validator and up to five saved items — no credit card required. Pro removes the daily limits and adds the full MCQ exam banks with timed exam mode, timed Cert Lab exam simulation, the AI assistant and the log analyzer.

Can it generate and translate configurations too?

Yes. The generator produces production-grade IPsec and SSL VPN, BGP, OSPF, NAT, firewall and hardening configs across every supported vendor, and the cross-vendor translator maps a config from one platform to another — built for migrations and multi-vendor environments. Every output is scored A to F by the validator.

Is it safe to use the AI features on my configs?

Treat generated configs and AI answers as expert drafts, not final deployable output: review them against the target platform before applying, and avoid pasting live secrets or credentials.
