5. © 2019 SPLUNK INC. What really is Splunk Phantom?

6. © 2019 SPLUNK INC. How We Got Started ▶ "Every battle is won or lost before it is fought." - Sun Tzu ▶ Our team had a clear vision ▶ Gather a relatively small team of talents with diverse knowledge pool ▶ Collect all the logs in Splunk ▶ Automate all the repetitive tasks ▶ Drink a lot of coffee tonic instead of work

7. © 2019 SPLUNK INC. Our Story ▶ Situation: ▶ We had to build log analytics and incident response capabilities from the ground up for a relatively big company in Denmark. ▶ Struggling with: ▶ Repetitive tasks, myriad of tools, slow webUIs, creating and maintaining internal processes ▶ Wanted: ▶ A Mission Control for investigations with in-depth documentation and automation capabilities. ▶ Enter Phantom: ▶ With Phantom we are now able to automate the boring tasks and document every step, it doesn’t matter if it’s automated or manual

8. © 2019 SPLUNK INC. Our 5 Step Journey with Splunk Phantom 1. Using Phantom for documentation and adding everything manually 2. Using applications in Phantom for semi-automate investigation processes 3. Chaining applications/actions together for creating playbooks 4. Customizing the playbooks with some custom code, if needed 5. Connecting Splunk and Phantom for more closer integration  Most notable alerts from Splunk ES are now forwarded to Phantom – automated ticket creation  Most of the tickets are automatically initiating enrichment actions – automated ticket enrichment  Advanced incident handling capabilities: Mission Control allows us to document and maintain our processes inside Phantom
