We build software.
Then we try to break it.
Code 42 is a software development house working with companies across Greece and Europe — product development, infrastructure architecture, penetration testing, and technical consulting, under one roof instead of four vendors.
One team, the whole stack
Code 42 started as one engineer taking on paid projects more than a decade ago. Six years ago it became a studio: a small team that designs the system, writes the code, architects the infrastructure it runs on, and then tests all of it the way an attacker would — instead of handing each piece to a different vendor who's never seen the rest.
Four disciplines, one accountable team
Each service stands on its own — most clients end up using more than one, because the same team already knows the whole system.
Software Development
Custom product and platform engineering — web, backend, and integrations, built to be maintained by the next engineer, not just shipped by this one.
Penetration Testing
Offensive security assessments that find what an automated scanner won't — web applications, infrastructure, and internal networks, tested like a real attacker would.
Infrastructure Architecture
Cloud and on-prem systems designed for the load — and the incident — you haven't had yet, not just for the demo day.
Consulting
Architecture reviews, technical due diligence, and hands-on advisory for teams making a decision they only get to make once.
Work we're proud to have our name on
Engagements across cybersecurity, retail, broadcast, industrial, and financial services — in Greece and beyond.
