The roast
Ismail, you list "Cybersecurity Leader of the Year 2025" in your headline as if you didn't invent the award yourself to pad a resume that reads like a LinkedIn profile was asked to hallucinate a personality. You have 15 years of "hands-on" experience yet your biggest credential is an alphabet soup of acronyms that act as a firewall against anyone ever actually wanting to talk to you.
About Ismail
In 2025, I was recognized as 🏆1st Cybersecurity Leader of the Year🏆, reflecting my commitment to building strategy-driven, resilient, and disciplined security programs. With over **15 years of hands-on cyber defense experience**, I currently serve as **CISO at ASEE**, overseeing threat-informed operations, post-quantum readiness, and resilient architectures across financial and payment systems. My journey started in **system & network administration**, but it was always the **“why” behind the breach** that intrigued me. This led to over a decade of service in the **Turkish Defense Industry**, where I held positions as **Red Team Operator, Cyber Forensics Specialist, Security Product Manager**, and finally **Technology Operations Director**. I built elite teams, orchestrated cyber defense strategies, and led incident response across critical infrastructures. I later transitioned into the private sector, contributing to both national and international firms such as the **American Turkish Council (Washington DC)**, **Comodo**, **ATAR Labs**, **Innovera**, **Netaş**, **KPMG**, and **Icterra**, focusing on threat intelligence, product security, and advanced SOC design. **📚 Author of Cybersecurity & Quantum-Focused Books:** I’m the author of several books that explore advanced threat landscapes, military-grade cyber strategy, and the intersection of **quantum technologies with cybersecurity**. 📘 **English (Amazon Author Page):** [https://www.amazon.com/stores/ISMAIL-ORHAN/author/B0FF384XJM] 📗 **Turkish (Kitapyurdu Author Page):** [https://www.kitapyurdu.com/yazar/ismail-orhan/264555.html] Books include: Kuantum Çizgisinin Ötesinde (Beyond the Quantum Line) Gizli Siber Cephe: İstihbarat ve Askeri Stratejiler (The Hidden Cyber Front: Intelligence and Military Strategies) Kuantum Dönüşüm Rehberi (Quantum Transformation Guide) 📰 **LinkedIn Newsletter – High-Tech Security:** * * https://www.linkedin.com/newsletters/high-tech-security-6868923440976424960/ 📰 **Spotify Podcast - "Siber Güvenlik 5.0 - Kuantum Dönemi" * * https://open.spotify.com/show/0CV1cVxu7lm3bbLGWqfPId?si=80ea6b90cc9b43fd If you're building quantum-resilient security or looking for strategic cyber advisory, speaking engagements, or thought leadership — I’d be happy to connect. 📬 Feel free to DM or reach out.

Quantum Computing in 2026: The Real Revolution Isn’t More Qubits One of the biggest misconceptions about quantum computing is that progress is measured simply by the number of physical qubits. In 2026, that is no longer true. The field is undergoing a profound technical transformation. The focus has shifted from building larger quantum processors to engineering fault-tolerant quantum computers capable of performing long computations with extremely low logical error rates. Among the most significant technical breakthroughs this year are: 🔹 Logical qubits that outperform physical qubits, d

🔴 Bu ülkede siber güvenlik neden bitmiştir? | Part 12 Türkiye’nin siber güvenlik sağlayıcıları küçülüyor. Siber güvenlik ürünü satan, entegrasyon yapan, SOC/MSSP, pentest, danışmanlık ve olay müdahalesi hizmeti sunan şirketler; ⚠️ Personel azaltıyor. ⚠️ Hizmet kapasitesini daraltıyor. ⚠️ Uzmanlık birikimini kaybediyor. ⚠️ Daha az kaynakla daha fazla müşteriyi taşımaya çalışıyor. Bir siber güvenlik sağlayıcısı küçüldüğünde; ❌ Hizmet kapasitesi azalır. ❌ Müdahale süreleri uzar. ❌ Danışmanlık yüzeyselleşir. ❌ Kurulum ve entegrasyon kalitesi düşer. ❌ Risk, hizmet verilen müşterilere yayılır.
