Sentinel-SIEM

Sentinel Security Platform

Sentinel is an enterprise-grade Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platform designed specifically for startups. It offers real-time threat detection, automated response capabilities, forensic investigation tools, and threat intelligence—all available for free as open-source software.

Why Choose Sentinel?

Competitive Edge

• Comprehensive Detection: Achieve the same detection capabilities as high-cost solutions such as Splunk, but without the hefty price tag (which can reach up to $150,000 per year).
• Inclusive Features: Unlike competitors that charge extra for response automation, forensics, and threat intelligence, Sentinel provides these essential features at no cost—all in a consolidated package.
• Rapid Deployment: Get from zero to operational in just 5 minutes, contrasting with lengthy multi-week setups typical of other solutions like Splunk.

Key Features

1. Real-time Threat Detection

   • Detects various threats such as brute force attacks, lateral movement, privilege escalation, and service degradation.
   • Supports over 7 log formats and recognizes temporal patterns, providing insights into multi-stage attacks.
