Cortex XSIAM Solution Brief
AI is rewriting the rules of cyberattacks. It's time for a SOC built to fight back. Discover how Cortex XSIAM unifies agentic AI, advanced analytics, and automation to stop threats faster, eliminate manual work, and reduce costs. Explore the capabilities powering the next generation of security operations.
Security operations are at a breaking point. As attacks accelerate to machine speed, SOC teams must navigate a maze of disjointed data, siloed tools, and unceasing alerts. They’re trapped in endless manual workflows that slow response and amplify risk.
Cortex XSIAM® ushers in the agentic SOC era by unifying data, AI-driven analytics, and automation into a single platform that continuously detects, investigates, and resolves threats in real time. By embedding agentic AI and intelligence directly into operations, teams can achieve faster time to resolution, stop attacks quickly and decisively, and drastically lower operational costs.
Despite years of investment, most security operation centers (SOCs) can’t keep pace with their fast-growing threat landscape. Their architecture remains anchored in legacy designs built for lower data volumes and slower attacks, leaving teams unable to keep up as conditions change.
This gap is widening fast. Now, agentic AI accelerates adversaries by as much as 100x and compresses the time from initial access to impact into minutes1. Traditional SOC challenges trace back to three fundamental problems.
Security data is divided across endpoints, network, identity, and cloud, with each system holding only a portion of the picture. Analysts must gather and align these signals themselves, moving across tools to construct the story of an attack after it has already begun.
Static correlation rules transform analysts into data integrators rather than threat hunters. Traditional security information and event managers (SIEMs) demand an exhausting cycle of querying. SOC engineers spend their time tuning detection logic and managing workflows, with progress tied directly to effort rather than system capability.
AI is often introduced as an overlay rather than a foundation. Chat-driven tools sit on top of existing systems, offering insights without addressing the root cause—disconnected data and siloed workflows. These bandage-type solutions only add complexity and governance challenges.
The result of these challenges is a collection of tools that never quite work together (figure 1), leaving teams to piece things together under pressure. Attackers move faster than teams can act, increasing security risk and driving up cost.

The autonomous SOC requires three foundational elements that work together:
It’s time to transform the SOC.
Cortex XSIAM transforms security operations by delivering the industry’s highest protection rate and leading SOC capabilities on a unified, agentic SOC platform. Organizations protect against frontier AI threats by having:
SOC teams move faster from detection to response with real-time, AI-driven analytics and automated triage. Threat hunters can search across all of your organization’s security data by using natural language queries that are enriched with Unit 42® intelligence to guide every investigation. The platform’s agentic AI plans and executes multistep workflows from a single prompt, compressing hours or days into minutes and bringing years of expertise into every decision.
Cortex XSIAM unifies data, AI, and automation on Cortex Extended Data Lake™ (XDL) to protect every attack surface, with optional 24/7 Unit 42 management (figure 2).
Figure 2: From proactive defense to real-time response, in one system
SOC transformation starts with unified data. Cortex XDL™ provides an extensible, AI-ready foundation for Cortex XSIAM, ingesting over 15 Petabytes daily to deliver real-time outcomes at scale.
Onboarding data into Cortex XSIAM is straightforward and flexible. With over 1,100 out‑of‑the‑box (OOTB) connectors and integrations, administrators can easily pull telemetry from any source, including cloud and on‑premises sources. They can choose the relevant integrations and provide credentials, and then, within minutes, the data begins streaming into the platform. AI-driven parsing simplifies ingestion of custom data sources, while a flexible pipeline gives teams control over data flow. The Federated Search capability enables teams to query external datasets at ultrafast speeds, eliminating the data tax of ingesting high-volume, low-value telemetry. The XSIAM Command Center provides unified visibility across data, detections, cases, and automated response activity (figure 3).
Figure 3: The XSIAM Command Center
Cortex XSIAM streamlines detection engineering by delivering accurate, up‑to‑date detection coverage from the start, without requiring heavy tuning. This agentic SOC platform ships with over 13,300 prebuilt and carefully tuned detectors, including 2,900 AI models. The prebuilt detectors and analytics satisfy well over 90% of detection requirements for most organizations, virtually eliminating custom rule work and slashing setup time and effort.
Advanced analytics and machine learning surface stealthy attacks, cut dwell time, and speed containment. By comparing hundreds of behavioral dimensions—many unavailable in traditional logs—to past behavior to cross-customer baselines, Cortex XSIAM pinpoints attacks with precision.
Because Cortex XSIAM pulls rich endpoint telemetry directly from the endpoints, not through a separate EDR platform, it finds attacks instantly. Teams don’t have to wait for data handoffs or third‑party alerts. When every second counts, this caliber of speed keeps defenders a step ahead of adversaries.
Cortex XSIAM ingests and stitches data across endpoints, networks, cloud, and more, creating a full attack context. Unlike basic SIEM correlation, stitching evaluates multiple elements of each event for higher accuracy and additional context, enabling better cross-data analytics, improved detection, and faster investigations. Data stitching powers SmartGrouping, which automatically consolidates related security issues into meaningful cases and reduces the alert volume by 75%.4
The AI-powered SmartScore helps analysts prioritize which cases to review first by using machine learning to assess risk. The SmartScore engine examines malicious artifacts, contextual details, and how other organizations resolved similar cases in the past to assign an AI-based risk score. Together, SmartGrouping and SmartScore help overwhelmed SOC teams decide which cases to tackle first and reclaim dozens of hours of manual effort each week.
Accelerate time to resolution with an intuitive case management experience that keeps everything in one place. AI-generated summaries capture what matters, visualized relationships connect events and entities, and the Resolution Center brings recommended, in-progress, and completed actions together into a single view. Analysts can trace activity to the root cause with automatic MITRE ATT&CK® mapping and work from a complete picture without switching between tools.

Cortex XSIAM orchestrates a response across the security stack by using over 1,300 prebuilt playbooks and more than 1,100 integrations, including native Model Context Protocol (MCP) support. Automation moves beyond static playbooks by using AI to adapt workflows as threats evolve. For custom use cases, the Automation Engineer Agent generates scripts and integration logic from natural language, eliminating manual coding and turning ideas into working automation in a fraction of the time.
A limitless AI workforce multiplies your team, solving the toughest security challenges and boosting analyst productivity. Contextual agentic assistance provides side-by-side support, guiding you through every investigation step and executing multistep workflows, with human-in-the-loop approval for sensitive actions. Enterprise-grade guardrails and controls ensure every action is governed, transparent, and auditable, enabling you to improve SOC performance without introducing risk.
“AI and automation are the secret sauce in XSIAM. We can now process massive datasets automatically.”
— Tamir Ronen, CISO, HiBob
Cortex XSIAM spots risky or malicious user behavior that traditional tools miss. The Identity Threat Detection and Response (ITDR) module profiles users by analyzing authentication, endpoint, network, cloud, and threat logs over time. By comparing current activity to established baselines, Cortex XSIAM flags credential theft, brute‑force attempts, and impossible traveler events. Cloud‑based analytics continually refine these algorithms, keeping pace with fast‑moving adversaries. ITDR alerts automatically correlate with related events, presenting a step‑by‑step view of each attack.
Legacy vulnerability management tools leave organizations drowning in unresolved vulnerabilities, with no clear path to fix them. An ESG survey reveals that nine out of 10 new vulnerabilities are unremediated on a monthly basis.5
Cortex® Exposure Management reduces vulnerability noise by up to 99% and prioritizes issues based on real risk. It consolidates vulnerability data from your network, endpoints, cloud, and third-party scanners to reveal attack vectors and remove redundant coverage. AI-driven plain-language summaries provide context to guide remediation at scale, while native playbook and workflow automation help resolve issues quickly across your environment, reducing exposures and improving your security posture.

Modern adversaries are using GenAI to craft realistic phishing attacks and speed the attack chain, making threats faster and harder to spot. Cortex XSIAM empowers security teams to stop AI-based email attacks with AI-driven, automation-fueled protection. It connects email threats to the full attack story—across identity, endpoints, and network—so you see more and remediate faster. By treating email as one part of a broader campaign, it quarantines messages, disables compromised accounts, and isolates affected devices in real time for precise, end-to-end response.
Cortex XSIAM also correlates email events with all relevant data to accelerate investigations, orchestrate phishing and business-email-compromise (BEC) responses at scale, and respond to attacks in a fraction of the time compared to manual email analysis.
Threat intelligence is useless if it isn't actionable. Overburdened SOC analysts don't need more raw data. They need immediate threat context to resolve active cases and understand how a threat impacts their environment. Cortex XTI brings high-fidelity Unit 42 threat intelligence and third-party intelligence sources directly into Cortex XSIAM workflows, reducing manual research and enrichment efforts. By correlating detection telemetry and threat intel data, XTI enriches active cases and issues with relevant adversary context and TTPs. This context helps analysts and AI agents investigate, reason, and make faster, more informed decisions, enabling more automated defense and workflows.
