Semgrep vs SentinelOne
Side-by-side comparison of AI visibility scores, market position, and capabilities
Open-source static analysis for security vulnerabilities and code quality in dozens of languages; commercial Semgrep Code and Supply Chain products serve enterprise security teams at scale.
About
Semgrep is an application security company founded in 2020 that has raised over $100M and built one of the most widely adopted open-source static analysis tools in the developer security ecosystem. The platform allows security engineers and developers to write custom code analysis rules in a readable pattern-matching syntax that mirrors the code being analyzed, making it far more approachable than legacy SAST tools. Semgrep supports over 30 programming languages and integrates into developer workflows through IDE plugins, pre-commit hooks, and CI/CD pipelines. The company offers Semgrep Code for SAST, Semgrep Supply Chain for dependency vulnerability scanning, and Semgrep Secrets for detecting hardcoded credentials. Semgrep has been widely adopted at major technology companies for internal security rule development and is used by security teams to enforce coding standards at scale. The combination of open-source community adoption and an enterprise SaaS offering has made Semgrep a leading platform-of-record for developer-first application security.
AI-powered endpoint security with $800M revenue; autonomous threat response and rollback on the Singularity Platform competing with CrowdStrike after CrowdStrike's 2024 global outage.
About
SentinelOne is a cybersecurity company providing AI-powered endpoint detection and response (EDR), extended detection and response (XDR), cloud security, and identity security through its Singularity Platform — using machine learning to detect and autonomously respond to malware, ransomware, and advanced threats in real time without requiring human intervention. Listed on NYSE (NYSE: S) and headquartered in Mountain View, California, SentinelOne generates approximately $800 million in annual revenue and competes with CrowdStrike for the enterprise endpoint security market.\n\nSentinelOne's Singularity Platform differentiates through autonomous response capability — when a threat is detected, the platform can automatically isolate infected machines, terminate malicious processes, roll back files to pre-attack states, and remediate damage without requiring a security analyst to approve each action. This "autonomous" response model reduces the threat dwell time and damage from fast-moving ransomware attacks that can encrypt thousands of files in minutes. The cloud-native architecture uses the Singularity Data Lake to correlate telemetry across endpoints, cloud workloads, and identities for unified threat detection.\n\nIn 2025, SentinelOne competes primarily with CrowdStrike Falcon for enterprise EDR/XDR market share — the two companies have become the dominant modern endpoint security vendors, having displaced legacy antivirus from McAfee and Symantec. The July 2024 CrowdStrike Falcon content update outage (which caused millions of Windows machines to crash) created a significant opportunity for SentinelOne, which accelerated customer acquisition in the months following. SentinelOne's 2025 strategy focuses on growing Purple AI (its generative AI security analyst that provides natural language threat investigation), expanding cloud workload protection, and growing identity security through its Singularity Identity product.
