Splunk
Splunk is a popular tool that helps companies make sense of their computer systems' data. Think of it like a super-powered search engine for all the information that IT systems generate. Companies use Splunk to spot problems before they become serious, track cyber security threats, and understand how their technology is performing. It's similar to tools like Elasticsearch or Datadog. Instead of manually looking through thousands of computer records, Splunk automatically collects, organizes, and helps visualize this information, making it easier for companies to understand what's happening in their systems.
