Gartner recently released a new category of security tools: the Integrated Security Operations Center (ISOC). This new category acknowledges the need to expand beyond traditional SIEM tools in the creation of a security portfolio, though, as they note in the introductory report, Security Information and Event Management (SIEM) isn’t going anywhere.
Gartner’s evolution away from SIEM as an all-encompassing category reflects another significant market shift in security operations. SIEMs are no longer sufficient to collect data, support investigations and manage incidents; instead, the SIEM has separated into distinct architectural layers. SIEM platforms, which remain the security system of record for collecting, normalizing, searching and analyzing event data, are now distinct from the Integrated Security Operations Center (ISOC) solutions. ISOC is tasked with unifying detection, investigation, case management and response across security domains and security/observability data pipelines.
As AI empowers attackers, this stratification becomes essential. Data management, analytics and operational response are now separate problems, demanding separate solutions. To reduce costs, latency and operational friction, the space for ISOC grows more distinct.
The goal of the new category, of carving out and defining ISOC, then, is instead to adapt and assess the ability of a vendor to integrate classic SIEM logic with an expanded threat detection and investigation and response (TDIR) capability. Reduced complexity is especially key for lean teams who prioritize efficiency and streamlined workflows, and the goal of ISOC is to reduce the friction that comes with conglomerating a wide variety of different security tools to contrive full visibility.
In short, ISOC puts its finger on the pain point that every security team faces today. A single vendor providing a flexible and adaptable, yet holistic and transparent security solution addresses both the increasing rate of alerts, as well as the adaptability crucial to combating them effectively.
In their ISOC report, Gartner also identifies the need to drive down costs, reduce deployment time and the unsustainability of currently growing SIEM complexities as the primary drivers for ISOC.
Common features of the ISOC, as Gartner writes, include native detection and response services, incident case management and extended case management of data ingestion. The goal of ISOC is to highlight the importance of reducing the friction between security tools and the latency between data, context, decision and action. In an age where threats occur and are deployed at machine speed, it’s essential that response doesn’t waste a single half second.
The necessity of ISOC is a result of latency challenges that businesses can no longer afford, in the following domains:
- Native detection and response. Detection and response must operate on the same underlying security data, not through loosely connected point products. Native controls reduce latency between signal, correlation, investigation and action.
- Security data ownership. ISOC starts with control of the data layer: ingesting, normalizing, enriching, retaining and making telemetry available for detection and AI reasoning. If the platform doesn’t control the data model, every downstream analytic or agent works through integration boundaries.
- Incident case management. Alerts, entities, evidence, timelines and analyst actions are assembled into a persistent incident object. The case becomes the operational unit for investigation and response rather than individual alerts.
- Cross-domain correlation. Endpoint, network, identity, cloud, application and third-party telemetry must be correlated against a common schema and context model. This turns weak individual signals into a high-confidence attack story.
- Automation and agentic response. Automation should operate directly against normalized data and incident context, enabling AI agents and playbooks to investigate, enrich, recommend and execute actions without repeatedly rebuilding context.
- Open ingestion and response fabric. ISOC must connect broadly to existing security infrastructure while minimizing translation and API friction. The objective is a common data and control plane where third-party tools contribute signals and become response surfaces.
Looking Ahead
Even though the SIEM market is predicted to continue to grow, the market share will be divided to include ISOC vendors, who will expand their offerings to include coverage in identity, cloud/Saas management and email security.
The market is only reflecting the dynamics that security teams have been feeling for years, which has been exacerbated exponentially by the adoption of AI by threat agents. Simply agglomerating more tools is neither strategic nor effective.
The market is confirming a foundational security thesis: modern operational needs demand integrated, unified capabilities. From setting an open integration standard to incorporating AI-native capabilities, ISOC environments are meant to simplify operations without compromising coverage or visibility.
Anticipating the limitations of fragmented security stacks leads to natively unified operational platforms. By normalizing raw data from any source through high-context schema technology, modern ISOC solutions deliver the precise, consolidated out-of-the-box outcomes now expected in the market.
With the creation of this new category, AI SOC is top of mind across the industry, and implementation and transparency remain key differentiators. Full-cycle detection and response rely on a case-centric approach. Rather than contending with an inundation of alerts, context-enriched cases give analysts the relevant information needed to respond quickly.
