Key topics for 2025

Cyber resilience: Attack detected, danger averted!

Digitalisation brings many opportunities – but also new challenges. Today, it is no longer just a matter of defending your company against attacks. The crucial question is: How do we remain capable of acting even if we become the target of a cyber attack?

Attackers are becoming increasingly professional, and the idea that good protective measures can prevent every attack is now wishful thinking. Instead, companies must set up their infrastructure and processes in such a way that they can quickly detect attacks and minimise their impact on operations.

This means knowing what to expect. Ransomware, phishing or other threats – those who understand what they are facing can develop the right strategies to build cyber resilience. Because in the end, it's not just whether you are attacked that counts, but how you respond.

Cyber resilience: Attack detected, danger averted!

Digitalisation brings many opportunities – but also new challenges. Today, it is no longer just a matter of defending your company against attacks. The crucial question is: How do we remain capable of acting even if we become the target of a cyber attack? Attackers are becoming increasingly professional, and the belief that good protective measures can prevent every attack is now a pipe dream. Instead, companies must set up their infrastructure and processes in such a way that they can quickly detect attacks and minimise their impact on operations. This means knowing what to expect. Ransomware, phishing or other threats – those who understand what they are facing can develop the right strategies to build cyber resilience. After all, it's not just whether you are attacked that counts, but how you respond.

Secure email: Trust in the digital world

Cybercrime and data leaks are no longer exceptions – they are part of our everyday digital lives. This makes secure and trustworthy email communication that can meet these challenges even more important. This section focuses on best practices and pitfalls: What can providers do to make their services more secure? And how can users leverage technology to better protect their communications? The DeepDives provide practical guidance, from using modern security features to implementing advanced protection measures. Because security starts with knowledge – and the willingness to apply it.

Secure digital infrastructures: The foundation of transformation

Without secure digital infrastructures, there can be no secure digital future. These infrastructures are the foundation for trustworthy applications and digital transformation. But the reality is often different: structures that have evolved over time are reaching their limits when it comes to withstanding modern applications and attacks.

This is not just about technology. Legal frameworks, market requirements and, above all, user acceptance are crucial when it comes to making digital infrastructures resilient and secure for the future.

In other words, only those who rethink their basic services will create a solid foundation for the digital world of tomorrow.

15. September, ab mittags - Workshop

Am 15. September findet unser Workshop mit dem Titel "E-Mail-Sicherheit für Unternehmen – Von der Compliance zum Wettbewerbsvorteil" statt.

In diesem Workshop vermitteln ausgewiesene E-Mail-Experten praxisnahe Strategien zur umfassenden Absicherung Ihrer geschäftlichen E-Mail-Kommunikation. Sie erfahren, wie moderne Sicherheitstechnologien wie DMARC, DANE, DNSSEC und TLS den ROI durch reduzierte Sicherheitsvorfälle messbar steigern und gleichzeitig Compliance-Anforderungen erfüllen.

Entscheider erhalten wertvolle Einblicke in die rechtlichen Implikationen, insbesondere im Kontext der NIS2-Richtlinie, sowie Argumente für die strategische Bedeutung von E-Mail-Sicherheit im Unternehmen, während technische Experten detaillierte Implementierungsrichtlinien und Best Practices zur nahtlosen Integration in bestehende IT-Infrastrukturen kennenlernen. Anhand praxisnaher Beispiele demonstrieren wir, wie führende Unternehmen durch strategische E-Mail-Sicherheit nicht nur Cyberrisiken minimieren, sondern auch Vertrauenswürdigkeit und Geschäftskontinuität stärken.

Profitieren Sie von der einzigartigen Kombination aus Branchenexpertise und behördlicher Perspektive – für eine zukunftssichere E-Mail-Sicherheitsstrategie, die technische Excellence mit messbarem Geschäftswert verbindet.

In diesem Jahr findet der Workshop am 15. September auch im RheinEnergieSTADION statt. Die Anzahl der Plätze ist stark limitiert (max. 25 Personen)!
