AI Security Analyst

Rahil Barchha

Threats spotted before they strike.

I'm Rahil, an AI Security Analyst who uses machine learning to detect, investigate, and stop threats before they cause damage. I turn raw security data into fast, clear decisions — catching attacks that traditional tools miss.

Naman Yadav

Breaking it first, so attackers can't.

I'm Naman, an AI Automated Pentester who uses AI to find and exploit vulnerabilities at scale. I automate the attacker's playbook — probing apps and networks faster than manual testing — so weaknesses surface before real attackers reach them.
