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.
Zscaler
Application
Governance layer for employee use of generative AI that discovers shadow AI applications, applies allow, block or coach policies per user, and monitors prompts and responses against more than 100 data loss prevention dictionaries to stop sensitive data leaving through AI tools.
AI security posture management that auto-discovers and classifies AI models, agents and services across Azure AI Foundry, Amazon Bedrock, Google Vertex AI and unmanaged providers, correlates the sensitive data connected to them, and maps findings to frameworks including NIST AI RMF 600-1 and the EU AI Act.
Runs AI models over the security data flowing through the Zero Trust Exchange, using attack graphs, user risk scoring and threat intelligence to score the probability of a breach, forecast an attacker's next tactics, and recommend policy changes before the attack completes.
AI-driven detection and diagnosis of digital-experience issues across the network and application delivery path.
Platform
Cloud-native security platform that inspects and enforces policy on every connection between users, devices, workloads and AI agents, rather than trusting anything on a corporate network.
No counterpart
SentinelOne sells these in a stack layer with no product recorded for Zscaler 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.
Zscaler sells these in a stack layer with no product recorded for SentinelOne yet — nothing on the other side to compare them against.
API service
Real-time guardrails for LLM traffic that inspect prompts and responses inline to block prompt injection, jailbreaks, sensitive-data leakage and toxic or off-topic output, deployed either as a proxy or as an API-based Detection as a Service.
Inline, AI-powered sandbox that analyzes unknown files in real time to block zero-day and file-based malware before it reaches endpoints, using AI/ML models trained on 600M+ samples.
Developer tool
Automated adversarial testing for AI applications and agents that runs simulated attacks using 25+ predefined and custom probes across text, image, voice and document inputs, scoring results for security, safety, hallucination and business alignment against MITRE ATLAS, NIST AI RMF and the OWASP LLM Top 10.
