Cyber Threat Intelligence, Entrepreneur, Presentation Virtuoso

the topic changes. curiosity does not.

Hello and こんにちは!

I am Scott Jarkoff (ジャーカフ スコット),

a threat intelligence and cyber security professional, entrepreneur, visionary leader, presentation virtuoso, cyclist, tech geek, and wannabe iPhone photographer living and working in the heart of Tokyo, Japan.

a powerhouse on-stage speaker, delivering electrifying and profoundly impactful keynotes that captivate, challenge, and inspire.

a remarkably creative presenter featuring incredible visuals combined with striking insights on cyber threat actors, their evolving tradecraft, and the attacks defining modern cyber warfare. I illuminate the future of generative AI in offensive operations, the shifting cyber security landscape, and the critical thought leadership shaping the next era of digital conflict.

I write about cyber security, sophisticated cyber adversaries, global cyber attacks, threat intelligence, the eCrime ecosystem and the dark web economy, leadership, global and domestic travel, hiking trips in Japan, and occasionally post various photos taken with an iPhone and meager composition skills.

I am the ambitious co-founder and mastermind behind deviantART, the largest and most vibrant online art community the world has ever seen, launched on August 7, 2000.

I am orchestrating the inception of Praeryx, a new cyber threat intelligence startup currently in deep development.

Finally, I live in Tokyo, Japan, where I architect and oversee these mission critical operations.

Reach out to me for inquiries.

Expertise Forged Under Pressure

Three decades across government and industry have forged a rare command of cyber security and threat intelligence. My experience spans technology and code, entrepreneurship, and the global stage. I have written software, scoured security logs, administered firewalls, and architected defense-grade systems. I have built companies, led exceptional teams, and directed regional intelligence strategy. I translate complex cyber realities into language understood from the engineering floor to the boardroom and the halls of government. In today’s sophisticated threat landscape, the ability to decode chaos into clarity and transform understanding into decisive action is not optional. It is imperative.

Intelligence

Built to an uncompromising standard, exposing hostile intent, anticipating the next move, and outmaneuvering the most capable nation-state adversaries by turning raw noise into advantage long before they strike.

Leadership

Exceeding expectations is only the baseline. I build and lead elite teams where innovation thrives, collaboration becomes a force multiplier, and elegant solutions achieve what others consider impossible.

Entrepreneur

Co-founder of deviantART and Praeryx, developing and building ambitious ventures, challenging established industries, and transforming revolutionary ideas into platforms, companies, and global communities with lasting impact.

Keynotes

Electrifying keynotes and commanding panel conversations exposing the forces reshaping cyber conflict, shattering conventional thinking, and leaving audiences with a radically clearer view of what comes next.

Fancy Bear is Mapping How Fast NATO Can Rebuild
