SentinelOne
Application
Discovers and governs employee and developer use of AI services, redacts sensitive data in prompts, controls autonomous agents and MCP servers, and defends custom AI applications against prompt injection, jailbreaks and data poisoning.
Cloud-native application protection platform that defends production workloads, cloud and AI infrastructure and the data stores feeding models, detecting and responding to threats autonomously across the cloud estate.
AI-powered endpoint security that combines endpoint protection, detection and response, and automated remediation and rollback in a single agent across Windows, macOS, Linux and cloud workloads.
Identity-security module of the Singularity Platform that protects against credential misuse and identity-based attacks.
On-device mobile threat defense for iOS, Android and ChromeOS that stops phishing, malware and risky apps with an on-device model and needs no cloud connection to detect.
Managed AI-assisted threat detection and response (MDR-style) service delivered by SentinelOne's global services team.
Platform
A security information and event management platform that ingests and normalizes cloud, identity, endpoint and third-party telemetry, correlates signals into incidents via Purple AI, and executes containment from the investigation console.
Umbrella platform that runs SentinelOne's endpoint, cloud, identity and mobile protection on one agent and console with autonomous detection, response and rollback; the modules a buyer licenses are recorded separately.
Splunk
Application
Integrated threat detection, investigation and response platform with agentic AI, SOAR, UEBA and SIEM unified into one SecOps experience.
AIOps and service-intelligence solution that uses AI-driven field discovery and AI-generated event correlation, summaries and root-cause guidance to connect IT events to business service health.
Observability platform where AI agents correlate signals across domains, propose remediation actions such as rollbacks or capacity changes, and provide dedicated agent/AI-system observability alongside infrastructure monitoring.
Platform
Assistant inside Splunk Cloud Platform that turns plain-English questions into SPL, the query language Splunk searches machine data with, and explains existing searches back to an analyst.
No counterpart
SentinelOne sells these in a stack layer with no product recorded for Splunk yet — nothing on the other side to compare them against.
AI agent
An agentic AI security analyst embedded in the Singularity Platform that auto-triages alerts, runs investigations and threat hunts, and recommends or executes response actions over OCSF-normalized SentinelOne and third-party telemetry.
Data service
A security telemetry pipeline service that filters low-value logs, normalizes heterogeneous sources into OCSF, and enriches events before they reach a SIEM, built on technology from SentinelOne's acquisition of Observo AI.
Splunk sells these in a stack layer with no product recorded for SentinelOne yet — nothing on the other side to compare them against.
Developer tool
Platform for building, deploying and running agentic AI systems on Splunk data.
