Summary
👤
Senior🎓
Top SchoolRoger Johnsen is a Lead Security Architect with 17 years of hands-on experience blending software development, SOC operations, and threat hunting to align defenses with real adversary behavior. Based in Kongsvinger, Norway, he focuses on turning assumptions about security maturity into measurable detection, response capability, and architectural clarity rather than paper metrics. At Orkla IT he operates outside day-to-day SOC production to test detection logic, expose structural blind spots, and connect threat intelligence, asset criticality, and organizational decision-making. He has built SOCs, led cross-functional security teams under tight budgets, and developed training programs and platforms to raise analytical maturity across organizations. Founder of Predefender and co-author of The Threat Hunt Book, he emphasizes practical, long-term capability building that forces defenders to prove what they can actually see and stop. An oft-overlooked strength is his background as a programmer and systems builder, which lets him translate attacker tradecraft into implementable detection engineering.
