AttackTree+ is a cybersecurity risk analysis tool developed by Isograph that helps organizations model, analyze, and quantify potential cyberattacks on systems and infrastructure. Using graphical attack tree models, it allows analysts to map how an attacker might compromise a system, evaluate different attack paths, and understand the likelihood and impact of those threats. By combining structured threat modeling with quantitative analysis, AttackTree+ helps organizations identify vulnerabilities, prioritize security controls, and make informed decisions to improve system resilience and reduce cybersecurity risk.
