Solving the Telemetry Gap: Integrating SIEM with EDR and Identity - 2026 Guide
Huntress combines Managed ITDR, Managed EDR, and Managed SIEM under one managed platform, bringing identity coverage for Microsoft 365 and Google Workspace together with endpoint detections and SIEM log data. In Huntress’s integrated workflow, related identity, endpoint, and log signals can be investigated as a single incident instead of as disconnected alerts.
Key Takeaways
Most security teams have a telemetry gap: their EDR, SIEM, and identity tools each see only part of an attack, and nobody's connecting the dots.
SIEM vendors that integrate with EDR and identity tools generally fall into three categories: large DIY platforms, single-vendor stacks, and managed platforms that handle integration and monitoring for you.
Huntress closes the telemetry gap with Managed SIEM, Managed EDR, and Managed ITDR working together under a 24/7 SOC — ingesting signals from its own EDR, third-party tools like CrowdStrike and SentinelOne, and identity sources like Microsoft 365, Entra ID, and Duo.
Additional integrations span firewalls (Fortinet, Palo Alto, Cisco, SonicWall), password managers (1Password, Bitwarden, Keeper, LastPass), and DNS/cloud tools — all correlated in one place.
With SIEM, EDR, and identity data under one SOC, Huntress drives mean time to respond down to ~8 minutes with less than 1% false positives — so the alerts you see are actually worth your time.
Why integrating SIEM with EDR and identity tools matters in 2026
Attackers don’t stay in one lane.
One stolen credential turns into endpoint access, lateral movement, and data theft through a cloud app—one incident, spread across four different telemetry sources. If your SIEM, EDR, and identity tools aren’t connected, you’re reconstructing the breach after the fact… if you can reconstruct it at all.
According to the Verizon Data Breach Investigations Report, about 88% of basic web application breaches involved the use of stolen credentials. Attackers are far more likely to just log in than “hack in” when identity, endpoint, and log telemetry aren’t tied together.
This is a big part of the reason why SIEM integrations with EDR and identity are non-negotiable in 2026.
Your SIEM needs to ingest endpoint signals from EDR, authentication and audit data from your identity provider, and then correlate it all with the rest of your environment—firewalls, DNS, SaaS logs, cloud events. When those signals land in one place with detections running across them, you stop chasing isolated alerts and start seeing attack chains.
But “integration” is a loaded word. Some SIEMs give you hundreds of connectors and then hand you the wrench—configure, tune, maintain, repeat. Others only work smoothly inside a single-vendor ecosystem: use their SIEM, their EDR, their identity stack—or accept blind spots.
There’s a third path: managed platforms that do the stitching, the detection engineering, and the 24/7 monitoring for you.
That’s our approach at Huntress. Managed SIEM, Managed EDR, and Managed ITDR can work together under a 24/7 SOC—so you get unified visibility across endpoint, identity, email, and logs without building (or staffing) your own SIEM program.
What's the "telemetry gap" between SIEM, EDR, and identity?
On a whiteboard, SIEM, EDR, and identity tools all look like they've got security covered. In practice, each one only sees part of the story:
EDR sees what’s happening on the endpoint right now — processes, persistence, malware, hands-on-keyboard behavior.
SIEM sees what’s happening across the environment over time — Windows Event Logs, firewall traffic, DNS, SaaS, cloud audits, VPNs, and more.
Identity (Microsoft 365 / Entra ID) sees who got in and what they did once inside — even when there’s no malware at all.
When those live in different tools with different owners, the gaps show up fast:
An account gets phished and used from a new country, but nobody has M365/Entra logs wired into anything anyone's actually watching.
A firewall screams about odd outbound connections, but without endpoint or user context, it's just another "maybe" in a noisy log.
A third-party EDR raises an alert that never gets correlated against Windows logons or identity activity.
Huntress closes that gap for teams that don't have time to become SIEM engineers:
Managed EDR gives deep endpoint telemetry and response.
Managed ITDR pulls in Microsoft 365 / Entra identity and email activity and enables identity-level remediation actions.
Managed SIEM ingests logs from endpoints, firewalls, cloud, SaaS, password managers, and identity providers, and lets the 24/7 Huntress SOC connect all the dots.
One story instead of three disconnected ones.
Which SIEM vendors integrate with EDR and identity tools?
If you're looking for SIEM vendors with EDR and identity integrations, you'll generally find three categories:
Big, DIY SIEMs that expect you to wire up all the EDR and identity provider integrations yourself, then build detections on top.
Tight, single-vendor stacks that basically say "use our SIEM, our EDR, and our identity tools, or you're on your own."
Managed platforms that integrate with what you already have, lean heavily into Microsoft, and do the heavy lifting for you.
Huntress lives in that third camp.
We ingest third-party EDR alerts from CrowdStrike Falcon, Cisco AMP / Secure Endpoint, and SentinelOne—but we don't try to be your MDR for those tools. We treat Microsoft 365 and Entra ID as first-class identity sources for both Managed ITDR and Managed SIEM.
We pull in additional identity-adjacent signals from Duo, password managers, DNS, and cloud tools so we can actually see how identities, endpoints, and network activity line up. And we use Smart Filtering and a human-led SOC to turn all of that into low-noise, high-value incidents—not another log dumpster with dashboards.
The result is XDR-style coverage for the 99% of organizations that aren't going to go all-in on one mega-suite or hire their own SIEM team.
Integration matrix: How Huntress connects SIEM, EDR, and identity
Here's the quick breakdown of how the Huntress platform ties everything together.
Signal / Tool Type | Key Partners / Sources | How It Lands in Huntress | What You Actually Get |
Endpoint EDR (first-party) | Huntress Managed EDR agents on Windows endpoints | The Huntress agent sends EDR telemetry and, when SIEM is enabled, Windows Event Logs straight into Huntress Managed SIEM. | Deep, real-time endpoint visibility plus historical log context on the same host during an investigation. |
Endpoint EDR (third-party alerts) | CrowdStrike Falcon, Cisco AMP / Secure Endpoint, SentinelOne | API and syslog integrations bring high-level alerts and audit data from these EDR platforms into SIEM. | One place to see endpoint alerts across a mixed EDR estate, monitored by the Huntress SOC—without us trying to manage those products for you. |
Identity & Email (ITDR) | Microsoft 365, Entra ID (Azure AD) | Direct Microsoft 365 / Entra integration via Microsoft Graph and Azure roles, plus Azure Event Hub for SIEM log ingestion. | Identity threat detection and response (ITDR) for account takeover, BEC, and unwanted access, with a full log trail in SIEM. |
MFA / Identity Signals | Cisco Duo | API log source into Managed SIEM. | Extra context around MFA and authentication, tied back to specific identities and machines. |
Password & Secrets Management | 1Password, Bitwarden, Keeper, LastPass | API and HEC sources feed vault, login, and admin events into SIEM. | Correlation of password-vault events with sign-ins, endpoint behavior, and suspicious admin activity. |
Network, DNS & Firewalls | Fortinet, Palo Alto, Cisco ASA / Meraki, SonicWall, Sophos, UniFi, WatchGuard, Barracuda, Cisco Umbrella, Cloudflare, DNSFilter, ScoutDNS, and more | Syslog via the Huntress Rio agent on a Windows collector, plus HEC/API for cloud-delivered services. | Visibility into lateral movement, suspicious egress, and DNS-based threats—without drowning in every last log line. |
How Identity, Endpoint, and SIEM Signals Correlate
When SIEM, EDR, and identity tools work together, they don't just collect more data. They let you see the full attack story in one timeline instead of reconstructing it from three separate consoles after the damage is done.
Here's what that looks like in practice, step by step:
The Signal Correlation Flow
1. Identity Event Detected
Managed ITDR flags an anomalous Microsoft 365 login. The account signed in from a country the user has never accessed before, outside business hours, from an unrecognized device. ITDR raises a medium-severity alert based on location, device posture, and sign-in risk score from Entra ID.
2. Endpoint Correlation Triggered
The Huntress AI-centric SOC doesn't stop at the identity alert. They pivot immediately into Managed SIEM to check: did this user's assigned endpoint show any suspicious activity in the same window? The SIEM query pulls EDR telemetry and Windows Event Logs from that machine for the past 48 hours.
3. SIEM Log Enrichment
The SIEM search surfaces a match. Twelve hours before the suspicious login, the user's endpoint showed credential dumping behavior (LSASS access by a non-system process). Firewall logs in SIEM also show that same endpoint started beaconing to a known command-and-control domain right after the credential dump. Now the SOC has the full chain: endpoint compromise led to credential theft, which led to account takeover from a remote location.
4. SOC Investigation
The Huntress SOC analyst reviews the correlated timeline. They confirm the user's legitimate session ended hours before the anomalous login. They identify two other accounts that authenticated from the compromised endpoint during the window between credential theft and remote sign-in—possible lateral movement targets. The analyst escalates a high-severity incident with a complete attack narrative, affected accounts, IoCs, and recommended containment steps.
5. Coordinated Remediation
Because ITDR, EDR, and SIEM are under one platform, remediation happens fast and in parallel:
- ITDR revokes the stolen account's active Microsoft 365 sessions and disables the account in Entra ID and on-prem AD.
- EDR isolates the compromised endpoint from the network.
- SIEM-driven blocklists push the C2 domain to the firewall for environment-wide blocking.
- The SOC validates that the two lateral movement targets show no signs of compromise and resets their credentials as a precaution.
Total time from initial ITDR alert to full containment: within minutes! Without correlation, this would have been three separate tickets, investigated by three different people, over three days—if anyone connected the dots at all.
Not every security tool sees every attack. That's the point of integrating SIEM with EDR and identity—each layer catches threats the others miss, and together they close the gaps.
Here's a breakdown of which layer detects which type of threat signal, and why having all three matters:
| Threat Signal | ITDR Catches | EDR Catches | SIEM Catches | Why Integration Matters |
|---|---|---|---|---|
| Anomalous login (impossible travel, unusual location) | ✓ Primary detection | — | ✓ Log context and history | ITDR flags the bad sign-in. SIEM shows the surrounding authentication attempts, failed logins, and whether the account was recently involved in other suspicious activity. |
| Token theft (post-compromise identity abuse) | ✓ Primary detection | — | ✓ Enrichment from endpoint logs | ITDR detects stolen tokens being reused across sessions or devices. SIEM traces back to where the token was harvested—often an endpoint compromise EDR logged days earlier. |
| Credential dumping (LSASS, SAM, registry) | — | ✓ Primary detection | ✓ Event log trail | EDR catches the technique at the process level. SIEM provides the Windows Security Event Logs showing which account ran the tool, when, and what else happened on that machine before and after. |
| Lateral movement (RDP, SMB, PsExec) | — | ✓ Behavioral signals | ✓ Primary detection via network and logon events | EDR sees unusual parent-child process relationships. SIEM logs show the actual network authentication events, account usage, and which machines the attacker touched across the environment. |
| Malware execution | — | ✓ Primary detection | ✓ Delivery and context | EDR detects and blocks the malicious binary. SIEM shows how it arrived—phishing email, web download, USB—and whether it touched other systems via shared folders or email forwarding. |
| Rogue inbox rule / mailbox delegation | ✓ Primary detection and remediation | — | ✓ Audit trail | ITDR flags and deletes the malicious inbox rule or suspicious delegate permission. SIEM provides the Microsoft 365 audit log showing exactly when the rule was created, by whom (or what compromised session), and what emails were affected. |
| Firewall beaconing / C2 traffic | — | ✓ Endpoint enrichment | ✓ Primary detection | SIEM catches the suspicious outbound traffic pattern. EDR confirms which process on which endpoint is responsible and whether it's persistence or a one-time execution. ITDR shows if any compromised accounts authenticated from that endpoint recently. |
| Failed authentication spike (brute force, password spray) | ✓ Detects success after spray | — | ✓ Primary detection of attempt volume | SIEM sees the full scope—hundreds or thousands of failed logins across multiple accounts. ITDR catches the one account that eventually succeeds and gets compromised after the spray. |
| Suspicious OAuth app / risky app consent | ✓ Primary detection | — | ✓ Consent event logs | ITDR flags the rogue OAuth app with excessive permissions. SIEM provides the consent audit trail showing which user granted access, when, and from which IP or device. |
What Happens Without Integration
When these tools don't talk to each other, you get:
- Blind spots: EDR catches malware, but nobody sees the stolen credentials that let the attacker back in days later with no malware at all.
- Alert fatigue: SIEM floods you with raw failed login events. ITDR raises anomalous sign-ins. EDR flags suspicious processes. Nobody correlates them, so every alert feels like a separate maybe-incident.
- Slow investigations: You're toggling between three consoles, rebuilding timelines by hand, and hoping you didn't miss the one log entry that ties it all together.
With the Huntress Agentic Security Platform, feed the same SOC, the same detection engine, and the same incident queue. The correlation happens automatically. The alert you see is already enriched with endpoint, identity, and log context, so you can act fast instead of investigating slow.
How Huntress brings SIEM, EDR, and identity together
1. Unified endpoint telemetry with Managed EDR
The Huntress agent does more than traditional EDR:
As EDR, it collects rich endpoint telemetry to spot long-lived footholds, LOLBins, and the usual attacker playbook.
As a SIEM collector, that same agent ships Windows Event Logs (Security and key Application logs). On collector hosts, the built-in Rio component also receives syslog from firewalls and other appliances.
What that means in practice:
No separate agent just to ship Windows logs.
No separate syslog box if you've already got a Windows host in the right spot.
Endpoint behavior, OS events, and local network telemetry all show up together in Huntress Managed SIEM, ready for both you and the SOC to pivot on.
Running third-party EDR like CrowdStrike Falcon, Cisco AMP / Secure Endpoint, or SentinelOne? Their alerts get ingested into SIEM via API or syslog too. We don't manage those consoles for you, but we use their signals alongside Huntress Maanged EDR and identity data to drive better investigations.
2. Identity as a first-class signal with Managed ITDR
Managed ITDR treats identity as the new endpoint.
It pulls identity and audit logs from Microsoft 365 and Entra ID via Microsoft Graph and the appropriate Azure roles. It watches successful sign-ins, locations, devices, OAuth apps, inbox rule changes, and mailbox configuration across Microsoft 365. It uses things like the Usage Location attribute in Entra to flag "this user should never be coming from that country" patterns.
When ITDR determines a Microsoft 365 identity is compromised, the Huntress SOC can:
Revoke active sessions.
Disable the UPN in Microsoft 365 / Entra.
Delete malicious inbox rules and cut off forwarding.
For AD-synced identities, the Huntress agent on domain controllers lets us disable and re-enable the account in on-prem AD and Entra at the same time—so Entra Connect doesn't quietly bring the account back from the dead.
Meanwhile, Managed SIEM is also ingesting Microsoft 365, Entra, Defender, Purview, and other Azure security events via Azure Event Hub. That gives you the surrounding log history—failed logons, policy decisions, and other raw signals that ITDR intentionally doesn't surface as noise.
3. Correlation and Smart Filtering inside Managed SIEM
All that telemetry lands in Huntress Managed SIEM, built around one idea: you need more signal, not more logs.
NIST’s Zero Trust Architecture (SP 800‑207) explicitly pushes defenders to stop trusting network location and instead make access decisions based on continuous verification of identities, devices, and resources—which is exactly what you get when SIEM, EDR, and identity signals land in one place and are monitored by the same SOC.
Here's how it works under the hood:
Logs hit a backend pipeline that keeps 30 days in hot, indexed storage (for fast search) and 12 months or more in cold storage for compliance.
A Smart Filtering engine acts like a sieve: it keeps security-relevant events and drops the low-value noise that just burns storage and patience.
The 24/7 Huntress SOC writes and tunes detections, monitors telemetry, and only raises curated incidents—not every firewall blip or failed login.
You still have search and retention for investigations, auditors, and legal. You're just not waking up to twenty "possible brute force" tickets every Monday.
Outcomes: Less noise, faster triage, stronger coverage
When SIEM, EDR, and identity feed into one managed stack, the point isn't "more data." It's fewer, better alerts and faster answers.
With Huntress, Smart Filtering and human-verified incidents mean you see far fewer raw alerts than you would with a traditional "ingest everything, forward everything" SIEM.
Across the platform, our SOC has driven mean time to respond (MTTR) down to about eight minutes, with 85% of alerts resolved within 15 minutes and 97% within 30—so investigations actually finish instead of piling up. On top of that, our managed approach keeps false positives under 1% while maintaining a 98.8% CSAT. That's a pretty good signal that the alerts you do see are worth your time.
Here's what that looks like when it's real:
Impossible travel + credential dumping: A user's Entra ID sign-in suddenly comes from an impossible travel location and, within the same window, the Huntress EDR agent sees credential-dumping activity on that user's endpoint. The Huntress SOC doesn't send you two separate alerts in two separate tools. You get one correlated incident that ties identity, endpoint, and log data together, along with clear guidance on isolating the host and disabling the account.
Firewall beaconing with clean endpoints: Your firewall starts beaconing to known malicious infrastructure but your endpoints look clean. Managed SIEM pulls together firewall logs, Windows Event Logs, and identity data so the SOC can tell you which accounts and machines are actually impacted—instead of leaving you to chase every noisy signature.
Conditional Access bypass: Conditional Access blocks a wave of risky logins but one attacker slips through. Managed ITDR flags the successful compromise—odd location, rogue inbox rules, suspicious OAuth app—and SIEM gives the surrounding history so you can show exactly what happened before and after the breach attempt for auditors and leadership.
Fewer junk alerts to wade through. Fast, well-informed triage when something real happens. A much clearer picture of how attackers move across endpoints, identities, and logs—without you having to glue it together by hand.
