Opal Security vs SentinelOne
Side-by-side comparison of AI visibility scores, market position, and capabilities
San Francisco CA identity access management platform; raised $22M+; self-service least-privilege access for cloud infrastructure, SaaS, and on-prem resources.
About
Opal Security is an identity-centric access management company founded in 2020 and headquartered in San Francisco, California. The company was founded by Umaimah Khan and Harlan Harris with the goal of making least-privilege access practical and scalable for fast-moving engineering organizations. Traditional privileged access management tools were designed for IT administrators and require significant configuration overhead, making them poorly suited for modern cloud-native companies where developers need rapid, self-service access to cloud infrastructure, databases, Kubernetes clusters, and SaaS applications.\n\nOpal raised $22 million in funding from investors including Greylock Partners and Battery Ventures. Its platform provides a developer-friendly self-service access request portal where employees can request access to specific resources, automatic approval workflows route requests to the appropriate resource owners for review, and time-bounded access grants expire automatically after a specified period. This just-in-time access model means permissions are granted only when needed and revoked automatically, implementing least-privilege without requiring manual IT tickets for every access change.\n\nOpal integrates with major identity providers including Okta, Azure AD, and Google Workspace, as well as cloud infrastructure platforms like AWS, GCP, and Azure, Kubernetes environments, databases, GitHub, and popular SaaS applications. Its governance features include access reviews, audit logs for compliance, and visibility into who has access to what across all integrated resources in a single pane of glass. Opal is particularly well-suited for companies that have outgrown ad hoc access management processes but want a modern solution that fits engineering culture.
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.
