The Best Agentic SOC for Microsoft Sentinel in 2026 (and Where Security Copilot Fits)

Vendor claims are dated at first sourcing and re-checked periodically; see the Source & Date column. D3 Security is a Microsoft Intelligent Security Association (MISA) member and holds itself to the same disclosure standard applied to every vendor on this page. That includes a limitations section for its own platform and an honest account of what Microsoft’s agents already do well.

The Short Answer

The best agentic SOC for Microsoft Sentinel in 2026 is D3 Morpheus: a MISA-member platform that autonomously investigates Sentinel alerts at L2 depth, triaging up to 95% of them in under two minutes. When Morpheus is uncertain, it defers to a human. It integrates natively and bi-directionally with Sentinel, Defender XDR, Defender for Office 365, Entra ID, and Intune, ships on Azure, and is purchasable with Azure committed spend your organization has already made. It also performs the same way across all three kinds of Microsoft estate (pure Microsoft, Microsoft-primary, and multi-vendor with Sentinel), because its 800+ integrations mean investigations don’t stop at the edge of Microsoft telemetry.

Security Copilot is the baseline for this question, not the competing answer. Copilot’s agents are useful where they’re GA (phishing triage), bundled with E5 since January 2026, and improving fast. Its most capable agents are still in preview, its triage coverage is a defined set of Microsoft alert types, and the investigations it starts still need an analyst to finish them. The full breakdown is below, agent by agent, GA versus preview.

The eight platforms ranked in depth:

1. D3 Morpheus: autonomous L2 investigation and governed response across the full Microsoft stack and beyond. MISA member, Azure-native procurement.
2. Dropzone AI: focused AI analyst with a solid Sentinel integration for smaller SOCs.
3. Prophet Security: multi-agent triage, hunting, and detection tuning atop Sentinel telemetry.
4. Radiant Security: high-coverage adaptive triage layered on Sentinel and the rest of the stack.
5. Simbian: zero-playbook triage, notable as a Microsoft Security Store launch partner.
6. Torq: workflow-first automation alongside Sentinel for engineering-heavy teams.
7. Conifers CognitiveSOC: multi-tenant mesh for MSSPs running many Sentinel workspaces.
8. Intezer: deterministic file-centric verdicts feeding Sentinel incidents.

All eight are scored on the AL1–AL4 autonomy scale from our agentic SOC platform rankings.

What an Agentic SOC for Microsoft Sentinel Actually Means

An agentic SOC for Microsoft Sentinel is an AI layer that autonomously investigates the alerts Sentinel raises, tracing root cause and blast radius across identity, endpoint, email, and cloud, then executes governed response without waiting for an analyst to drive each step. Sentinel remains the SIEM: the data layer, the detections, the incident queue. The agentic layer is what happens after detection: the investigation and response work that, in most Sentinel deployments today, still lands on a human queue. We covered the architecture of that layer in more depth in The Governed Autonomy Layer for Microsoft Sentinel.

Microsoft itself has endorsed this architecture. Sentinel was repositioned in late 2025 as an “agentic defense platform”: the Sentinel data lake went GA, Sentinel Graph and an MCP Server opened the data to AI reasoning, and the Microsoft Security Store launched so partner-built agents can deploy directly into the Defender experience. The strategic message is unambiguous. Sentinel is the foundation agents build on, and Microsoft expects other people’s agents to build on it. For a SOC leader the question is no longer whether an agentic layer belongs on Sentinel. It is whose, and how autonomous.

Here is the practical test for anything claiming to be an agentic SOC for Sentinel. When an analytics rule fires at 3 a.m., does the platform investigate to a completed, evidence-backed conclusion on its own, including the parts of the attack that touched systems outside Microsoft? Or does it summarize, recommend, and wait?

Security Copilot: What It Does Well, and Where It Stops

Any honest answer to “what’s the best agentic SOC for Sentinel” has to start with the option you may already own. Security Copilot has been included in Microsoft 365 E5 product terms since January 1, 2026, with tenant rollout phased April 20 through June 30. That makes it the most widely deployed agentic capability in the Microsoft ecosystem by default. Here is the state of its agents as of July 2026, GA versus preview.

Three structural realities frame what Copilot is today.

Copilot is an assistant with autonomous features, not an autonomous SOC. Its GA capability triages one alert family. Its investigation agent is in preview. Everything else operates in assist mode: an analyst asks, Copilot answers. On the autonomy scale, that’s AL2 in production with AL3 in preview. An assistant makes your analysts faster at investigating. An agentic SOC platform investigates. If your alert queue is the bottleneck, acceleration and completion are different products.

Copilot’s reach is Microsoft’s telemetry. Its agents reason over Defender, Sentinel, Entra, and Purview signals. That is exactly right for a Microsoft-first product, and it is exactly the boundary that matters the moment an attack path crosses into CrowdStrike, Okta, AWS, Proofpoint, or any of the third-party tools that exist in almost every real estate. The alert fires in Sentinel. The attack rarely stays there.

Preview timelines are a planning risk, not a footnote. Microsoft’s history of preview features maturing slowly is well documented in its own community. A SOC that budgets 2026 operations around preview agents is scheduling its coverage against a roadmap it doesn’t control.

None of this is a reason to skip Copilot. It’s bundled, so deploy the GA agent and take the free win. It is the reason “we have Copilot” doesn’t answer the investigation-gap question, and why Microsoft built a Security Store for everyone else’s agents.

The Three Microsoft Estate Types (Which One Are You?)

Every Sentinel environment falls into one of three estate types. The right agentic layer depends on which one you are, and on which one you’re becoming.

Two things follow from the table. First, estate type is temporary. Consolidation pushes estates toward Microsoft, acquisitions and best-of-breed purchases push them away, and most organizations move between types over a platform’s contract life. An agentic layer that only performs in one estate type charges you a migration tax every time your stack strategy shifts. Second, the honest question for any vendor on this page, including Microsoft, is which estate types their platform actually serves. That question anchors the rankings below.

How We Evaluated: Microsoft-Specific Criteria

Beyond the standard agentic criteria (architecture, autonomy level, audit trail; see the full framework), a Sentinel-specific evaluation adds six.

1. Sentinel integration depth: alert and incident ingestion is the minimum. Does the platform sync bi-directionally, so statuses, severities, and notes stay aligned in both systems? Can it manage multiple Sentinel workspaces and tenants?
2. Microsoft stack breadth: native coverage of Defender XDR, Defender for Office 365 (email), Entra ID (identity), and Intune (device). We score each Microsoft surface separately.
3. Beyond-Microsoft reach: what happens when the attack path leaves Microsoft telemetry. Integration count and investigation continuity across the boundary.
4. GA discipline: what’s production today versus preview or roadmap. We score shipped capability only.
5. Azure-native procurement: Azure Marketplace availability, deployability on Azure, and whether purchase can draw down Azure committed spend (MACC). That turns a new-vendor procurement cycle into an existing-budget transaction.
6. Copilot coexistence: whether the platform complements the Copilot agents you’re getting with E5 or fights them for the same queue.

The 8 Best Agentic SOC Platforms for Microsoft Sentinel

1. D3 Morpheus: Best Agentic SOC for Microsoft Sentinel

Autonomy ceiling: AL4 (bounded, policy-gated) · Microsoft integrations: Sentinel (bi-directional), Defender XDR, Defender for Office 365, Entra ID, Intune · Total integrations: 800+, self-healing

D3 Morpheus is the governed autonomy layer for Sentinel. It picks up the alerts Sentinel raises and autonomously investigates them at L2 depth (root cause, blast radius, lateral movement) across identity, endpoint, email, cloud, and device telemetry, delivering a completed, evidence-backed investigation in under two minutes on up to 95% of alerts (D3-verified customer-reported metric). When Morpheus is uncertain, it defers to a human. Copilot’s agents triage defined alert types and its investigation agent is still in preview. Morpheus runs the full investigation lifecycle in production today, then executes response under command-risk policy across four autonomy levels, with every incident on one audit trail.

The Microsoft partnership is structural, not a logo. D3 Security is a Microsoft Intelligent Security Association (MISA) member. The Sentinel integration is bi-directional. Incident statuses, severities, and notes stay synchronized in both systems, so Sentinel remains the source of record while Morpheus does the investigative work. Native integrations span the operational Microsoft stack: Defender XDR for endpoint and correlation, Defender for Office 365 for email threats, Entra ID for identity (the alert domain Microsoft’s own triage agent is only now entering in preview), and Intune for device management and response actions. Multi-workspace and multi-tenant Sentinel management is native, which is why MSSPs running many Sentinel customers standardize on it.

Procurement runs through the budget you already have. Morpheus ships on Azure and is available through Azure Marketplace, purchasable with Azure committed spend your organization has already made. Azure-benefit-eligible marketplace purchases contribute 100% of pretax value toward a MACC when transacted through the Azure portal (confirm current offer eligibility with D3). For teams whose committed Azure spend is under-consumed, that converts an agentic SOC evaluation from a net-new budget request into a burn-down of an existing commitment.

The boundary problem doesn’t exist here. Morpheus performs identically across all three estate types. In pure Microsoft environments it deepens what E5 detects. In Microsoft-primary estates it follows attack paths across the Microsoft boundary into CrowdStrike, Okta, AWS, or whatever else is present. In multi-vendor estates, Sentinel is one first-class source among 800+. Your stack strategy can change; the investigation layer doesn’t.

Limitations: Morpheus is not a Microsoft product. The Copilot portal’s native experiences (promptbooks, natural-language KQL assistance) remain Microsoft-only, and teams that want only conversational assistance over their logs don’t need a platform. Autonomous depth scales with connected telemetry, so the thinnest estates see proportionally thinner investigations, and onboarding is a scoped implementation, not a same-day connection.

Best for: Sentinel environments of every estate type that need production-grade autonomous investigation now: deep in the Microsoft stack, unconstrained beyond it, procured through Azure. → Morpheus + Microsoft Sentinel integration · Morpheus vs. Security Copilot vs. Logic Apps: the full report · Book a 30-minute demo on your Sentinel alerts

2. Dropzone AI: Best Focused AI Analyst for Small and Mid-Sized SOCs

Autonomy ceiling: AL2–AL3 · Sentinel integration: Alert ingestion + investigation write-back · Total integrations: 90+

Dropzone’s AI analyst ingests Sentinel alerts and investigates them 24/7 at L2 depth, returning readable investigation write-ups analysts trust. For smaller Sentinel shops, roughly 20 to 100 alerts a day, it’s one of the fastest routes to autonomous triage on a Sentinel queue, with cloud onboarding measured in days and published pricing from about $36K/year.

Sentinel-specific reality: the integration ingests alerts and reports findings, so deep bi-directional operations are out of scope, and response execution stays with your existing tooling: Logic Apps, manual runbooks, or a retained SOAR. Per-investigation pricing also means a noisy Sentinel analytics rule is a billing event, so tune before you connect.

Limitations: Triage-layer scope by design. Orchestration, case management, and multi-workspace Sentinel operations are thin. Identity- and cloud-heavy Microsoft estates should validate investigation depth on Entra-centric alerts specifically.

Best for: Smaller Sentinel environments that need overnight triage relief without a platform project.

3. Prophet Security: Best Mid-Market Multi-Agent Play for Triage, Hunting, and Detection Engineering

Autonomy ceiling: AL3 · Sentinel integration: Triage + detection-tuning feedback on Sentinel analytics · Total integrations: 80+

Prophet fields coordinated agents for triage, threat hunting, and detection tuning, and it comes up often in Sentinel-specific evaluations. The detection-tuning agent is the differentiated piece for Sentinel shops: it feeds back into the analytics rules generating your alert volume, so noise drops at the source.

Limitations: Growth-stage vendor risk for a system this operationally central; response execution depth trails platform-class options; multi-tenant Sentinel operations are not the design center.

Best for: Mid-market Sentinel teams that want agentic coverage across reactive and proactive work and can tolerate early-stage vendor risk.

4. Radiant Security: Best Adaptive Triage Layer on an Existing Stack

Autonomy ceiling: AL3 · Sentinel integration: Full alert-stream ingestion · Total integrations: 100+

Radiant’s promise maps cleanly onto a noisy Sentinel deployment: adaptive agentic triage across up to 100% of alerts (vendor-stated), including alert types no one anticipated, with explainable reasoning and vendor-stated false-positive reduction around 90%. For Sentinel estates drowning in analytics-rule noise, it’s a high-coverage investigation layer that deploys without touching the underlying workspace.

Limitations: It’s an investigation layer, not an operations platform. Response depth depends on wired integrations, and Sentinel-specific operational features (bi-directional incident sync, multi-workspace management) trail the platform class.

Best for: Enterprises with a mature Sentinel deployment that want the triage half of the problem solved at maximum coverage first.

5. Simbian: Best Zero-Playbook Triage Play

Autonomy ceiling: AL3–AL4 (vendor-positioned) · Sentinel integration: Alert ingestion; Microsoft Security Store presence · Total integrations: Growing

Simbian investigates Sentinel alerts with no authored playbooks at all, and it holds a distinction worth noting honestly: it was among the launch partners of the Microsoft Security Store, meaning its agentic capability is deployable through Microsoft’s own distribution channel into the Defender experience. That’s meaningful validation of its Microsoft alignment.

Limitations: The standing caution from our SOAR alternatives analysis applies doubly in Sentinel estates: reasoning is the product’s center of gravity, so validate response-execution depth against your Logic Apps and automation-rules reality before decommissioning anything. Early-stage vendor risk applies.

Best for: Sentinel teams whose defining pain is triage volume and who want reasoning-first relief immediately, with execution decisions made deliberately.

6. Torq: Best for Workflow-First Automation Teams

Autonomy ceiling: AL3 · Sentinel integration: Deep workflow connectors across Sentinel and Defender · Total integrations: Large library

For Sentinel shops with real automation engineering capacity, Torq’s hyperautomation engine plus HyperAgents (coordinated by its Socrates orchestrator) is the strongest workflow-first option, and a modern replacement for the Logic Apps sprawl many mature Sentinel deployments accumulate. IDC has validated that Torq customers automate more than 95% of Tier-1 analyst tasks.

Limitations: The authored-workflow trade: coverage equals what your team builds and maintains against the Sentinel schema, and pricing couples cost to workflow execution and agent compute, so model a noisy month. Investigation autonomy is bounded by the workflow inventory.

Best for: Engineering-heavy Sentinel teams that want composable automation and accept workflow ownership. → Morpheus vs. Torq

7. Conifers CognitiveSOC: Best Multi-Tenant Multi-Agent Mesh

Autonomy ceiling: AL3 · Sentinel integration: Works atop client Sentinel deployments · Total integrations: Client-stack driven

For MSSPs running many customer Sentinel workspaces, Conifers’ mesh of shared-memory agents was built for the shape of the problem: natively multi-tenant, tenant onboarding in hours, per-tenant tuning of investigations against each client’s Sentinel content. Among the mesh architectures it’s the strongest service-provider fit.

Limitations: Mesh-class audit composition (per-agent logs an auditor must stitch) and a younger enterprise reference base. For MSSPs specifically, evaluate how tenant-isolated Sentinel write-back is handled against a platform with native bi-directional multi-tenant sync.

Best for: MSSPs and multi-team SOCs standardized on Sentinel per tenant, who prefer a mesh architecture.

8. Intezer: Best for Malware Forensics and File-Centric Verdicts

Autonomy ceiling: AL3 (file-centric verdicts) · Sentinel integration: Alert enrichment + verdict write-back · Total integrations: Broad alert sources

Intezer grounds verdicts in deterministic analysis: sandboxing, code genetics, and reverse engineering. That makes it the strongest verdict engine for the malware, phishing, and endpoint slices of a Sentinel queue. As a complement feeding high-confidence verdicts into Sentinel incidents, it’s excellent. Teams pairing it with Copilot’s GA phishing agent should delineate which system owns which alert family to avoid double-triage.

Limitations: The deterministic edge is file- and code-centric. Entra identity alerts, cloud-control-plane events, and business-logic detections (a large share of a typical Sentinel queue) lean on conventional reasoning. Orchestration and response are not the product’s center.

Best for: Sentinel estates whose alert mix skews malware and phishing heavy, and regulated teams needing forensically defensible verdicts.

Also Relevant for Sentinel Estates

Microsoft Security Store partner agents: the growing catalog of third-party Security Copilot agents deployable directly into the Defender experience (launch partners included Accenture, Darktrace, IBM, ServiceNow, Simbian, and Zscaler). These are scoped task agents, not full agentic SOC platforms, and worth watching as the catalog matures. Logic Apps and Sentinel automation rules: Sentinel’s built-in SOAR layer, deterministic (AL1) and maintenance-heavy at scale, which is precisely the burden the platforms above exist to retire. Exaforce, Qevlar AI, and 7AI: covered in our full agentic SOC platform rankings.

Side-by-Side Comparison: Agentic SOC for Sentinel 2026

Two tables for readability and chunk coherence. Vendor-stated figures are claims, not audits, so validate on your own Sentinel alert stream in a proof-of-value. Security Copilot is included as the bundled baseline every option should be compared against.

Table 1: Microsoft Integration & Capability

Table 2: Commercial & Operational

The Marketplace and MACC column reflects positioning verified as of July 2026. Procurement eligibility should be confirmed per offer at transaction time, because only Azure-benefit-eligible offers purchased through the Azure portal decrement a MACC.

How to Choose, by Estate Type

Pure Microsoft (E5 everything). Deploy Copilot’s GA phishing agent immediately. It’s bundled and it works. Then measure what remains: every non-phishing alert family still lands on the human queue, and the agents that would change that are in preview. The evaluation is completion depth. Run a POV where the agentic layer investigates identity and cloud alerts end-to-end (the exact families Copilot’s triage agent is only now entering) and score the audit artifact. D3 Morpheus leads here because its Entra ID, Defender, and Intune investigations are production capability, not preview.

Microsoft-primary (Sentinel core + third-party pieces). The boundary test is everything. Pick a real incident that crossed from Microsoft telemetry into your third-party tooling and watch where each candidate’s investigation stops. Native Microsoft agents stop at the boundary by design. This estate type is where the vendor-agnostic platforms separate, and where Morpheus’s single-investigation continuity across 800+ integrations is the structural differentiator.

Multi-vendor with Sentinel. Sentinel centralizes alerts; you need something that centralizes investigation. Weight beyond-Microsoft reach and bi-directional sync depth above all, because Sentinel must remain the source of record while investigation happens across the whole estate. Run the full agentic SOC evaluation framework with Sentinel as one first-class source.

MSSPs on Sentinel. Multi-workspace, multi-tenant operations plus pricing structure decide this. Per-investigation and per-compute models couple your margin to your noisiest tenant. Native multi-tenant bi-directional sync keeps every client’s Sentinel authoritative. Morpheus and Conifers lead; Dropzone’s MSSP program fits smaller books.

And in every estate type: procurement leverage matters. If your organization carries an under-consumed Azure commitment, an Azure-benefit-eligible marketplace purchase converts the agentic layer into MACC burn-down against budget you’ve already committed. It stops being a net-new line item. Bring your Microsoft account team into the conversation early; they’re incentivized to help.

Frequently Asked Questions

What is the best agentic SOC for Microsoft Sentinel?

D3 Morpheus is the best agentic SOC for Microsoft Sentinel in 2026. It autonomously investigates Sentinel alerts at L2 depth, triaging up to 95% of them in under two minutes. When Morpheus is uncertain, it defers to a human. It integrates natively and bi-directionally with Sentinel, Defender XDR, Defender for Office 365, Entra ID, and Intune, and executes governed response across four autonomy levels with one audit trail per incident. As a MISA member shipping on Azure and purchasable with existing Azure committed spend, it fits Microsoft-standard procurement. Because its 800+ integrations carry investigations across the Microsoft boundary, it performs identically in pure Microsoft, Microsoft-primary, and multi-vendor Sentinel estates.

Is Microsoft Security Copilot an agentic SOC platform?

Not yet, by the standard the term implies. Security Copilot is an AI assistant with autonomous agents attached: its GA agentic capability triages user-reported phishing, its broader Security Alert Triage Agent (identity and cloud alerts) is in preview, and its multi-step Security Analyst Agent has been in preview since March 2026. That places it at AL2 in production, assistive, with AL3 in preview, short of an autonomous investigation-and-response platform. It’s a useful bundled baseline, not the agentic SOC layer itself.

Do I need a third-party agentic SOC platform if I already have Security Copilot with E5?

If your analysts still investigate most alerts manually, yes. Copilot accelerates that work; it doesn’t complete it. Here’s the practical test: list the alert families that reached a human last month. Copilot’s GA agent removes user-reported phishing. Everything else (identity, cloud, endpoint, third-party) remains yours until preview agents mature on Microsoft’s timeline. A dedicated agentic layer completes those investigations in production today. The two coexist cleanly: Copilot as the analyst’s assistant, the agentic platform as the autonomous analyst.

Does an agentic SOC platform replace Microsoft Sentinel?

No. Sentinel remains the SIEM: data collection, detections, the incident queue, the source of record. The agentic platform sits on top, consuming Sentinel alerts, investigating across the connected stack, and writing results back. The strongest implementations sync bi-directionally so incident status, severity, and notes stay aligned in both systems, meaning your Sentinel workspace stays authoritative while the investigation work happens autonomously.

Which Security Copilot agents are GA versus preview right now?

As of July 2026: the Phishing Triage Agent is GA (user-reported phishing through Defender for Office 365 P2). The Security Alert Triage Agent, the same agent extended to identity alerts (password spray, BEC inbox rules, post-spray compromise) and cloud and container alerts, is in preview, rolling out from April 2026. The Security Analyst Agent (multi-step investigation across Defender and Sentinel) has been in preview since March 26, 2026. Purview’s DLP and Insider Risk triage agents are also preview. Microsoft labels all of these preview, so don’t build production workflows on them yet.

Can I buy an agentic SOC platform with my Azure commitment (MACC)?

Yes, if the platform is available as an Azure-benefit-eligible offer on Azure Marketplace and you transact through the Azure portal: eligible purchases contribute 100% of the pretax amount toward your Microsoft Azure Consumption Commitment. D3 Morpheus ships on Azure and is available through Azure Marketplace, purchasable with Azure committed spend your organization has already made. Confirm current offer eligibility with D3 and your Microsoft account team at transaction time, since eligibility is set per offer and purchase path.

Does an agentic SOC for Sentinel also cover Defender, Entra ID, and Intune?

It should. That’s the difference between a Sentinel alert-reader and a Microsoft-stack investigator. Sentinel raises the alert, but the evidence lives in Defender XDR (endpoint), Defender for Office 365 (email), Entra ID (identity), and Intune (device). D3 Morpheus integrates natively with all of them, which is what lets a single investigation trace an attack from a phishing email through an identity compromise to device actions, then execute response in the right system. Evaluate any candidate on investigation continuity across those four surfaces, not connector checkboxes.

What is the best agentic SOC for MSSPs running Microsoft Sentinel?

D3 Morpheus leads for MSSPs on Sentinel: native multi-workspace and multi-tenant management with bi-directional sync per tenant, hard data isolation, white-labeling, and subscription pricing where the AI is in the platform price, not on a usage meter. Conifers CognitiveSOC is the strongest mesh-architecture alternative, built MSSP-first with hours-scale tenant onboarding. The screening criterion is pricing structure: per-investigation or per-compute models couple MSSP margin to the noisiest tenant’s Sentinel queue.

What is the Microsoft Security Store?

The Microsoft Security Store, launched in late 2025, is Microsoft’s catalog for deploying partner-built Security Copilot agents directly into the Defender and Sentinel experience. Launch partners included Accenture, Darktrace, IBM, ServiceNow, Simbian, and Zscaler. It’s Microsoft’s structural acknowledgment that first-party agents won’t cover the field. Store agents today are scoped task agents (report generation, specific investigations), not full agentic SOC platforms, and the two approaches complement each other.

How much does an agentic SOC for Sentinel cost compared to Security Copilot?

Security Copilot’s baseline is bundled with E5 as of January 2026, with additional consumption billed through Security Compute Units, so cost scales with usage. Third-party platforms span per-investigation pricing (Dropzone from ~$36K/year), per-workflow and per-agent compute (Torq), and subscription pricing (D3 Morpheus, where the AI is in the platform price, not on a usage meter). Two Sentinel-specific factors change the math: MACC applicability can fund a marketplace-transacted platform from committed spend, and consumption-metered models, Microsoft’s included, make noisy analytics rules a billing event. For the per-alert benchmark we hold the category to, see Agentic SOC Triage Economics.

Final Thoughts

Microsoft settled the architectural argument itself. Rebuilding Sentinel as an agentic platform, opening it with MCP, and launching a store for other people’s agents is a declaration that the agentic layer on Sentinel is real, necessary, and open. What Microsoft hasn’t settled is the operational gap between a GA phishing agent plus preview investigators and a SOC that needs every alert investigated tonight. Deploy the Copilot capability you’re already paying for. Be disciplined about GA versus preview. Then put the completion problem to a production-grade agentic layer, evaluated on your own Sentinel alerts, across the Microsoft boundary, with the audit artifact on the table.

See Morpheus on Your Sentinel Alerts

D3 Morpheus adds the governed autonomy layer Sentinel doesn’t ship: autonomous L2 investigation across Sentinel, Defender, Entra ID, Intune, and everything beyond them, triaging up to 95% of alerts in under two minutes with one audit trail. When Morpheus is uncertain, it defers to a human. MISA member. Ships on Azure. Purchasable with the Azure spend you’ve already committed.
