About

Hey there! I'm Ruchira. 👋 I'm a content creator (@cyberwithru on YouTube, instagram and TikTok) and a full-time Senior Threat Detection Engineer at a US based financial services company. Think of me as a digital detective who spots and stops hackers before they can cause harm. But let me tell you how I got here! 🚀 My journey started as a software engineer, evolved into ethical hacking, and led me to incident response at a FAANG company, where I helped major businesses and customers recover from cyber attacks and data breaches. With a double masters in Computer Science & Cybersecurity, I've spent the last 7 years learning how to keep people and organizations safe online. After years of helping victims recover from devastating cyber attacks and seeing how these incidents destroy lives and families, I realized my true calling: preventing these attacks from happening in the first place by educating people. I believe everyone deserves to feel safe online, not just big companies with security teams. So think of me as your cyber-savvy friend who's got your back! I'll break down the complicated stuff into bite-sized tips that you can actually use. Want to stay safe online? Follow along for daily tips that won't make your head spin! ✨
