Jan Kaastrup
Jan Kaastrup is a partner and long‑standing cyber security expert with experience across industries and organisations. He has advised companies, public authorities and media on cyber threats, digital risk and practical security leadership.
Summary
Over the years, Jan has worked professionally with cyber and IT security, advising private companies and public organisations on everything from strategic security work to the handling of concrete attacks. The combination of technical insight and business understanding makes him a sought‑after adviser, speaker and commentator.
- • Cyber and IT security at a strategic level
- • Governance, risk & compliance
- • Incident response and handling of attacks
- • Advisory to executive teams and boards
- • Communicating complex threats to a broad audience
As a partner, Jan combines his cyber security background with a focus on strategy, governance and long‑term value creation. He works to help build resilient organisations that can handle both the technical and organisational aspects of the evolving threat landscape.
Career and key contributions
Throughout his career, Jan has worked with a wide range of organisations and has followed the development of the threat landscape from early malware to today’s more advanced, targeted campaigns.
Jan has acted as an adviser to organisations looking to strengthen their digital resilience. This includes building security strategies, implementing technical and organisational controls and supporting leadership teams during security incidents.
His work has covered both preventive security initiatives and support in acute situations where organisations have been hit by serious attacks and needed to restore operations, trust and governance.
A recurring theme in Jan’s career is the ability to explain complex topics in a way that resonates with both technical and non‑technical audiences. Through books, TV programmes, talks and interviews he has helped raise awareness of cyber threats in the general public.
His work as a communicator has made cyber security concrete for many who otherwise only encounter it through headlines and isolated incidents.
The book “Usynlig Fjende”
As part of making cyber threats more understandable to a broader audience, Jan wrote the book “Usynlig Fjende” (“Invisible Enemy”). The book describes how digital attacks can affect both companies and individuals, and how organisations and people can relate to this reality.
- • How the cyber threat landscape has evolved
- • Examples of concrete attacks and incidents
- • What organisations can do to protect themselves
- • The role of leadership, culture and awareness
The book is written as an introduction to cyber security for readers without a technical background who want a realistic view of how the “invisible enemy” operates and what can be done to reduce risk.
TV series, live hacking and media coverage
In addition to his advisory and authorship work, Jan is known for a number of prominent appearances in Danish media, where he has demonstrated and explained cyber threats in practice.
Jan has taken part in all episodes of the TV series “Jaget Vildt”, where IT security and digital footprints play a central role. The series gives viewers rare insight into how digital tools can be used to locate and follow people in practice, and how the same technologies raise important ethical and security questions.
In a segment on the morning show “Go’ Morgen Danmark”, Jan demonstrated live how a compromised environment can be used to gain access to a user’s computer. As part of a controlled demonstration, he hacked host Morten Resen’s computer to show how surprisingly little is sometimes required for an attacker to gain control.
Jan has appeared in several national news programmes and current affairs shows, where he has been used as an expert source in cases related to cyber attacks, data breaches and digital threats against public authorities and businesses.
He is regularly quoted in articles on cyber and IT security, contributing analysis and explanations of current attacks, vulnerabilities and the general threat development. The common denominator is a focus on clear, concrete explanations rather than technical jargon.
