-## About Us
+## Use Cases
 
-We are a San Francisco based [startup](https://www.crunchbase.com/organization/panther-labs) comprising security engineers who have spent years building large-scale detection and response for companies including Airbnb, Amazon, Riverbed, and more. Panther was founded by the core architect of [StreamAlert](https://github.com/airbnb/streamalert/), a cloud-native solution for automated log analysis open-sourced by Airbnb.
+Panther works by analyzing security-relevant data generated by your clouds, networks, applications, and hosts to enable threat detection, cloud security, and investigations.
 
-Panther is the next step for security teams who need a modern alternative to traditional SIEMs. We designed Panther for massive scale, with a rich and intuitive user experience, in-browser Python rule editing, and first-class AWS support.
+Panther provides flexible Python detection logic, secure and automated deployments within your AWS cloud, and support for popular security logs, commonly used for:
 
-Our mission is to provide an open platform to effectively protect businesses from cybersecurity threats.
+- **Detecting Malicious Behavior:** Analyze logs to identify unauthorized or suspicious activity
+- **Threat Hunting:** Quickly search for matches against indicators of compromise, extracted into common data fields
+- **Achieving Compliance:** Use [built-in policies](https://github.com/panther-labs/panther-analysis) as controls for achieving SOC/PCI/HIPAA compliance
+- **Securing Cloud Resources:** Model security best practices with Python policies and automatically fix misconfigurations with automatic remediation
 
-## Use cases
+_NOTE: Panther is currently in beta_
 
-Panther analyzes all security data generated by your clouds, networks, applications, and hosts to power threat detection, compliance, and security investigations. Panther provides flexible detection logic, a secure deployment within your AWS cloud, support for common security tools, and automation for painless deployments. Common uses include:
+## Deployment
 
-- **Detect Unauthorized Access:** Analyze logs to identify unauthorized access into systems
-- **Threat Hunting:** Quickly search logs for matches against indicators of compromise with Panther's standardized data fields
-- **Achieve Compliance:** Use [built-in detections](https://github.com/panther-labs/panther-analysis) as controls for SOC/PCI/HIPAA compliance
-- **Secure Your Cloud Resources:** Automatically fix misconfigurations that could cause severe damage if exploited
+Follow our [Quick Start Guide](https://docs.runpanther.io/quick-start) to deploy Panther to your AWS account in a matter of minutes!
 
-_NOTE: Panther is currently in beta._
+## Why Panther?
 
-## Deployment
+It's no longer feasible to find the needle in the security log haystack _manually_. Many security teams have struggled to solve this problem with SIEMs and traditional log analytics platforms due to their high cost, overhead, and scale.
 
-Follow our [Quick Start Guide](https://docs.runpanther.io/quick-start) to deploy Panther to your AWS account in a matter of minutes!
+Panther utilizes the elastic nature of serverless cloud services to provide a high-scale, performant, and flexible solution at a much lower cost. Panther also comes built-in with a rich and intuitive user interface, built-in detections, and first-class AWS support.
