Unlike conventional PenTest labs where you train on vulnerable-by-design servers, the CTF365 Platform provides Security Professionals with the opportunity to train on real servers created by real users. CTF365 doesn't limit your training scope. As a security professional, you can use your existing arsenal of PenTest tools, discover new tools, and test new tools.

CTF365 is a top-notch security training platform that offers five-star offensive and defensive security training services.
On CTF365, System Administrators are targeted by attackers from all over the world. Like a flight simulator for pilots, CTF365 gives System Administrators the ability to execute threat responses without real risks.
With CTF365, you can test new setups and configurations without concern of damaging your production systems. More importantly, you can improve your defensive security without risk of real exposure. With our “Private Hack Notifications," we reduce your need to be connected to CTF365 24/7.
With the help of CTF365's large community of users, web developers and programmers can have their code and web applications tested for vulnerabilities such as SQL Injection (SQLI), Cross Site Scripting (XSS), Security Misconfiguration, Sensitive Data Exposure, Missing Function Level Access Control, and Cross Site Request Forgery (CSFR).
Pimp your server” and learn hands-on how to protect your applications.

Think of "World of Warcraft" or "Second Life" for hackers where you can practice SQL injection, Deface, DDoS, Brute Force, Sniffing, MiTM etc.
