Top 5 SentinelOne Alternatives for 2025 Cloud Security

Why look for an alternative to SentinelOne?

• Perceived Pricing Complexity or Cost: Some users might find Sentinel One's tiered pricing structure, which varies based on features and the number of endpoints, complex to understand or potentially expensive, especially for smaller organizations or those needing specific features without the full suite. For instance, while the basic "Core" package starts at a lower price per endpoint annually, accessing more advanced features like managed threat hunting or identity protection in the "Commercial" or "Enterprise" tiers significantly increases costs. This mirrors the concern about paying for unused features in SentinelOne.
• Feature Set Focus: While Sentinel One excels in endpoint security with AI-powered prevention, detection, and response across various operating systems, organizations seeking broader XDR (Extended Detection and Response) capabilities that deeply integrate network security, cloud, identity, and email security might find its native capabilities less comprehensive compared to some alternatives. Similar to how SentinelOne users might seek broader cloud security features, SentinelOne users could look for more out-of-the-box integration and correlation across multiple security layers like Trend Micro.
• Integration Needs: Depending on an organization's existing security stack, seamless integration with other tools (like SIEM, SOAR, or specific cloud platforms) is crucial. While Sentinel One offers API-driven integrations, some users might find the level of integration or the ease of setup with their specific ecosystem less optimal compared to alternatives that are built with broader integration and best practices in mind.

If these pain points sound familiar, the following SentinelOne alternatives offer compelling solutions.
