About Breached

CYBERSECURITY
DOESN'T
STAND STILL.

Neither do I. Breached was built around one simple idea: cybersecurity education should reflect the industry as it exists today — not the industry from years ago.

01 / THE IDEA

BECAUSE CYBERSECURITY ISN'T A TEXTBOOK.

Attack techniques evolve. Cloud environments change. AI is creating new attack surfaces. Security teams are adopting new tools every year.

That means cybersecurity training has to evolve too.

02 / THE MENTOR

Learn from someone who is still in the arena.

I'm not teaching cybersecurity from a textbook. I'm teaching it from the perspective of someone who has spent years working with security technologies, teams, systems and real-world problems.

I've had the opportunity to mentor more than 1,200+ graduates, help freshers move toward high-paying cybersecurity careers, interview more than 500+ cybersecurity consultants for top firms, and work with 50+ organizations to help secure their infrastructure.

03 / THE JOURNEY

FROM TECHNOLOGY
TO BREACHED.

THE FOUNDATION

TECHNOLOGY

Started by understanding how systems, networks and applications actually work.

THE SHIFT

SECURITY

Moved deeper into cybersecurity, vulnerability management and offensive security.

THE ENGINEERING

SECURITY ENGINEERING

Built and operated security capabilities across modern enterprise environments.

THE MENTORSHIP

TEACHING

Started helping students and professionals turn cybersecurity knowledge into practical capability.

THE MISSION

BREACHED

Created a training ecosystem focused on skills, labs, tools and career readiness.

04 / THE INDUSTRY
ALWAYS MOVING

THE INDUSTRY
KEEPS CHANGING.

Network security became cloud security. Endpoint detection became XDR. Vulnerability management became continuous exposure management. AI is creating another generation of attack surfaces.

05 / WHAT I TEACH

BUILD
CAPABILITY.

Not just terminology. Not just theory. The goal is to understand how security actually works across modern environments.

01

SOC & DEFENSIVE SECURITY

Detection engineering, SIEM, EDR, incident response and security operations.

02

OFFENSIVE SECURITY

Ethical hacking, penetration testing, reconnaissance and adversary simulation.

03

THREAT HUNTING

Investigate suspicious activity and hunt for threats across enterprise environments.

04

CLOUD SECURITY

AWS, Azure and GCP security concepts, misconfigurations and attack surfaces.

05

APPLICATION SECURITY

Web, API, secure coding, vulnerability discovery and DevSecOps.

06

AI SECURITY

Understand emerging LLM threats, prompt injection and AI attack surfaces.

07

OT / ICS SECURITY

Industrial environments, network visibility and operational technology security.

08

SECURITY ENGINEERING

Build, automate and improve security controls in real-world environments.

06 / THE SECURITY TOOLKIT
INDUSTRY TOOLING

THE TOOLS
BEHIND THE SKILLS.

Candidates don't just learn concepts. They get exposure to the tools used across offensive security, SOC operations, vulnerability management, cloud security, threat hunting and security engineering.
