We have some tools, such as our off-site Meraki firewalls, that have not fully integrated with Sentinel.

Threat detection and response capabilities enhance investigation processes
My security team has been using Microsoft Sentinel for around two years. We also have Bastion and SolarWinds as part of our monitoring tools. We use a three-way tool, alongside Microsoft Sentinel, in our environment The most valuable features for us include threat collection, threat detection,…

Enables optimization by reducing manual intervention and increasing automation in the workflow
The product provides 100% automation for certain processes. It needs no manual intervention. We can integrate various tools like VirusTotal and ServiceNow. We can automate all the tasks. It is one of the best things about the tool. It also provides workforce protection. Whenever we get any alerts or make any configurations, we develop workflow automation using the playbooks. We can fully automate some of the security incident resolutions. We can also do identification and redirection using the product. I have integrated Splunk Phantom with Splunk Cloud. Previously, I used it with Splunk on-premise to get the logs into Splunk for tracking and audit purposes. Since Splunk is a SaaS-based product, it has certain maintenance windows. Over time, the vendor does some maintenance during off-production hours. Creating playbooks using the solution’s playbook editor is not tough. For someone who knows the solution, I rate the ease of creating playbooks as four out of five. The solution’s playbook viewer provides full visibility. The product provides different integrations. We can easily integrate the tool with VirusTotal, ServiceNow, and the asset and identity management system. The product is somewhat easier to use in an investigation. We have been able to identify the false positives using the product. The tool has helped reduce false positives by 30%. Splunk SOAR has helped reduce our mean time to detect by 10% to 15%. Splunk SOAR has a major impact on our meantime to resolve. Our mean time to resolve has been reduced by 35% to 40%. I have integrated VirusTotal with Splunk SOAR. Instead of doing manual checks, I can easily get the score by integrating the tool with Splunk SOAR. I have also synced Active Directory with the asset and identity management system. It's been a long time since we have implemented Splunk SOAR. It brings value to our organization. Before Splunk SOAR, everything was done using manual intervention. We had to educate the SOC team on how to do tasks. We also had to create playbooks for them. With Splunk SOAR, we only have to educate the team about how things are done so that they can perform a manual intervention when there is a failure, which is rare. After deploying the product, we had to provide some training to the SOC team. After getting trained, it was hands-on. Along with other Splunk solutions, Splunk SOAR provides the resilience to face any issues and hardships. We easily cope with downtimes. Splunk SOAR offers us end-to-end visibility across our environment. It depends on how much we utilize it. Visualizing and troubleshooting our cloud-native environment using Splunk SOAR is somewhat easy. I have to coordinate with the Phantom administrators if there is any issue. I work mostly on playbook development and integrating it with security instances.
