What is an integrated security operations center (ISOC)?

An integrated security operations center (ISOC) brings security information and event management (SIEM), threat intelligence, threat detection, investigation, incident response, automation, and AI SOC agents into one operating model. It gives security teams one place to manage security events, identify potential threats, and coordinate response actions across their security infrastructure. An ISOC is a security operations center (SOC) designed as one integrated system. Security analysts use a shared investigation workbench instead of stitching together multiple security tools and separate workflows. According to Gartner, the category was introduced and defined in March 2026.

Key takeaways

An ISOC brings SIEM, threat intelligence, detection, investigation, response, automation, and AI into one operating model.
A SIEM collects and analyzes security data. An ISOC connects that work to the wider SOC workflow.
A shared workbench gives analysts more context without switching between multiple tools.
AI and automation speed up triage and reduce alert fatigue. Human judgment remains essential.
An effective ISOC stays open, connecting with the security tools an organization already uses.

ISOC and SIEM: What changes

A SIEM platform collects, normalizes, monitors, investigates, and reports on security information from across an organization's environment. It gives SOC teams a strong foundation for event management and threat detection. The team then builds the rest of the SOC around it, including connectors, detection rules, threat intelligence feeds, playbooks, case management, and automation.

An ISOC puts the integration work into the platform. Connectors, detection content, threat intelligence, workflows, and response actions are designed to work together. SIEM remains one of the core SOC functions, but it operates within a broader security operations platform.

The difference is operational. With a standalone SIEM, the team assembles and maintains the surrounding system. With an ISOC, the vendor delivers more of that operating model as a working whole.

Category	SIEM	ISOC
Purpose	Collects and analyzes security logs.	Runs the wider security operations workflow.
Core capabilities	Log management, correlation, detection, and alerting.	SIEM plus threat intelligence, investigation, automation, and response.
AI and automation	Usually limited or added separately.	Built into workflows such as triage, investigation, and response.
Analyst experience	Analysts often move between several tools.	More capabilities are unified in one platform.
Simple distinction	The SOC’s detection and data engine.	The SOC’s integrated operating environment.

The six core capabilities of an ISOC

According to Gartner, an ISOC brings together:

SIEM core functions: Ingests, normalizes, monitors, investigates, and reports on security information from third-party tools and the vendor's own products.
One operating ecosystem: Brings together, at minimum, SIEM, endpoint detection and response (EDR), threat intelligence, and AI SOC agents.
One point of management: Coordinates playbooks, automation, and response actions.
Native threat intelligence: Enriches detections and supports threat identification with intelligence built into security workflows.
Cross-product collaboration: Applies automation and artificial intelligence across the platform through one control plane.
One investigation workbench: Gives analysts cross-product investigations, enriched detections, and AI guidance.

How an ISOC supports daily SOC operations

An ISOC connects the work that security teams already perform across the attack surface.

Continuous monitoring: Collects and analyzes security events from endpoints, mobile devices, identity systems, network traffic, cloud environments, and cloud workloads.
Threat identification: Correlates security data across multiple security tools to find attack techniques, potential threats, and signs of compromise.
Incident response: Gives incident responders the context and response actions they need for rapid incident response, while helping protect business continuity.
Threat hunting: Lets threat hunters and other specialists proactively search for hidden threats, emerging threats, and advanced persistent threats that automated detections can miss.
Security improvement: Tracks security metrics, detection quality, response times, and recurring gaps so teams can strengthen their organization's security posture.

Automation, machine learning, and artificial intelligence can group related security alerts, tune detection rules, reduce false positives, and limit alert fatigue. Human expertise still matters. Skilled cybersecurity professionals, experienced security analysts, qualified security analysts, security engineers, and incident responders make the decisions that shape response.

Why security teams move to an ISOC

Simpler SOC operations: Teams spend less time configuring connectors, tuning detection rules, and maintaining separate workflows.
Fewer security tools: Organizations select, integrate, and support fewer products.
Faster analysis: Machine learning and AI can help security teams process more security events and prioritize meaningful alerts.
A practical model for lean teams: Smaller SOC teams can use vendor-maintained integrations, detection content, and response workflows.
Faster time to value: Shorter evaluations and quicker deployments can help teams improve security operations sooner.

An ISOC does not remove the need for human expertise. Threat hunters, security analysts, and incident responders still assess context, make decisions, and adapt to emerging cyber threats. The platform gives them a unified view and stronger response capabilities.

Integrated and open

Gartner notes that some ISOC offerings trade open extensibility for ease of use. They may also deliver their full value only when every core component comes from the same vendor.

An ISOC still needs to connect to the organization's attack surface and existing security infrastructure. Before choosing a platform, security leaders should ask:

Can we keep the EDR, firewall, identity systems, and other security tools we already run?
Can our managed security service provider (MSSP) operate the platform for us?
Where is our security data hosted, and who controls it?
Can we export our security information and security metrics when we need to?

Open integrations matter because the most useful security data often sits across multiple products and cloud environments. A unified platform should reduce operational work without forcing every organization to rebuild its security stack.

How Sekoia approaches the ISOC

The Sekoia autonomous cyber defense platform combines integrated security operations, an open architecture, and threat intelligence from Sekoia Intelligence.

Integrated: Native SIEM, SOAR playbooks, response actions, cyber threat intelligence (CTI) from Sekoia's threat research team, and AI agents that triage, enrich, and investigate security alerts. Analysts keep the decisions, while one console supports cross-source investigation.
Open: More than 300 integrations connect the platform to the EDR, firewall, cloud services, and other security tools an organization already uses. Sekoia maintains the connectors, parsers, detection content, and playbooks.
Threat intelligence-led: Threat intelligence feeds and research help security teams identify emerging cyber threats and attack techniques. Threat hunters proactively search security data for hidden threats that automated detection may miss.
Built for MSSPs: A multi-tenant platform lets security service providers deliver integrated detection and response for every client from one environment.
European data control: Organizations can host the platform according to their data security requirements and retain control over their security information.
Fast to deploy: New clients can be onboarded in hours, subject to the scope of the deployment.

The goal is practical. Security teams get continuous monitoring, threat detection, threat hunting, and incident response in one operating model. They can use human expertise where judgment matters and automation where speed helps.

What is the difference between an ISOC and an autonomous SOC?

ISOC describes how the platform is built and bought, as one integrated system. An autonomous SOC describes how operations run, with AI agents handling tasks such as triage and investigation at machine speed while enabling security teams to make the decisions. The Sekoia autonomous cyber defense platform supports both models.

How does an ISOC help with alert fatigue?

An ISOC can correlate related security events, enrich alerts with threat intelligence, apply detection rules consistently, and automate defined response actions. These capabilities help security analysts focus on security incidents that require human judgment.

Does an ISOC replace a SIEM?

An ISOC builds on SIEM. SIEM functions remain its core, delivered alongside threat intelligence integration, response automation, and AI agents in one system.

Can an MSSP deliver an ISOC?

Yes. A multi-tenant platform lets security service providers run integrated detection and response for every client from one environment.

What should an organization check before adopting an ISOC?

Check integration coverage, data hosting and control, support for existing security tools, MSSP operating models, response capabilities, and the quality of the vendor's threat intelligence and detection content.
