Was jetzt?
Security
Operations
1. Welcher Alarm ist der
wichtigste?
2. Wie erhalte ich mehr
Informationen im Kontext?
3. Wie bestätige ich eine
Infektion? (ohne “False
Positive”)
4. Wie kann ich mich schnell
schützen und eingrenzen?
5. Wie kann ich die eigene
Effektivität messen?

Kundenvorteile
Threat Response beschleunigt den Prozess:
Verstehen & Priorisierung von Bedrohungen
Infizierungen bestätigen (Vergleich forensischer Infos)
Reagieren auf Bedrohungen (FW/Proxy/AD Integration)
Geschäftliche Vorteile:
Senkt die Zeit der Nachforschung um > 50%
Um bis zu 20-fache Beschleunigung der Reaktion
Reduziert die Belastung und das Risiko bei zeitgleich
weniger Arbeit
