Threat-Informed Cybersecurity Solutions
Daniel Thomas Heessel
Daniel Thomas Heessel has led cybersecurity at international corporations and has been an ISMS auditor for years in parallel. Since 2024 he runs his own firm, Threat-Informed Cybersecurity Solutions GmbH, specialised in Threat-Informed Defense. His practice book on the topic is published in 2027 by Rheinwerk Verlag.
For years he has decided on two sides: as CISO, which certifications he requires for his team, and as auditor, which ones are actually recognised in an audit. What comes together there is the data basis behind CertMap.
