Security foundations
Start here: how computers, networks and attackers work, with no experience needed.
Every path is self-contained and engineered to build tangible offensive, defensive, or AI safety skills. Complete virtual rooms, capture flags, defeat boss rooms, and earn verifiable certifications.
Start here: how computers, networks and attackers work, with no experience needed.
Learn how attackers map a target before touching it, so you can spot it as a defender.
What AI and large language models really are, how to prompt them well, and how to use them safely.
How web apps talk and where they break: injection, XSS and broken access control.
Ports, scanning your own assets, firewalls, cryptography and hardening Linux.
Use AI to triage, investigate, code-review, detect and report faster, with humans in control.
Read logs, respond to incidents, preserve evidence and write the report.
Professional pentest method, Active Directory, cloud, bug bounty, AI-assisted testing and malware triage.
Threat-model and defend AI apps: prompt injection, data leakage, excessive agency, RAG and supply chain.
No. Path 01 (Security Foundations) starts from absolute scratch. We introduce how the Internet works, what an IP address is, basic command line navigation, and common threat models in plain, straightforward language with interactive checks.
Yes, completely free. You can enroll in Security Foundations, Recon Foundations, and AI Foundations, complete all 21 rooms, take the timed certification exams, and earn 3 public verifiable credentials without ever entering a payment card.
Unlike traditional multiple-choice memorization tests, Devwalls certifications require hands-on proof of skill. You must solve practical problems, capture flags, and pass rigorous timed examinations. Every issued credential comes with a public, tamper-resistant verification link that employers can verify in one click.
Yes! We work directly with campus tech societies, computer science departments, and corporate security teams across Nigeria, Kenya, Ghana, South Africa, and internationally. See our Plans page or contact enterprise@devwalls.com.
