Open XDR improves threat detection accuracy by over 8x compared to SIEM-only approaches
MSPs gain faster response times, consolidated reporting, lower operational costs and scalable security revenue
This guide explains how Open XDR integrates your existing stack without vendor lock-in
What problem does Open XDR solve for MSPs?
No MSP set out to manage 15+ different security tools per customer, unfortunately this is now the industry norm. As a result, teams face tool silos, slow investigations and poor visibility into multi-vector attacks. Traditional SIEM is not enough because it requires complex rule building, high data storage costs and significant analyst time. Endpoint-only security leaves blind spots across cloud, network, identity and SaaS.
Open XDR solves this by unifying signals from every existing tool into one place with contextual correlation built-in. It enables MSPs to see attacks across the full kill chain and automate investigation workflows to reduce manual effort.
What makes Open XDR different from SIEM or EDR?
Open XDR is not a replacement for SIEM or EDR. It enhances and unifies them. EDR looks at endpoint behaviour. SIEM collects logs. Open XDR connects everything across data sources and security tools.
Organisations using XDR experience a 60 percent faster Mean Time to Detect and a 70 percent faster Mean Time to Respond compared to SIEM alone. This is because Open XDR applies analytics and correlation across endpoint, network, cloud, identity and email data, not just endpoints.
How does Open XDR integrate with existing MSP tools?
Open XDR connects to your existing tools through built-in connectors. For example, Stellar Cyber includes over 400 native integrations. That means you can plug in tools like:
SentinelOne or CrowdStrike for endpoint
Fortinet, SonicWall or WatchGuard for firewalls
Microsoft 365, Google Workspace and Okta for SaaS and identity
Proofpoint or Mimecast for email security
AWS CloudTrail and Azure for cloud workloads
NDR sensors to monitor lateral movement
Threat intelligence feeds including VirusTotal and AbuseIPDB
Instead of replacing tools, Open XDR integrates them to improve their value through correlation. This protects prior investments and avoids vendor lock-in.
How does Stellar Cyber deliver Open XDR for MSSPs?
Stellar Cyber is designed specifically for MSSPs and MSPs. It was built from the ground up as an open, multi-tenant platform. Multi-tenancy makes it possible to manage hundreds of customer environments from one central dashboard. It separates customer data and enables role-based access, white labelling, separate reporting and per-tenant policy control.
Stellar Cyber also integrates ITDR, UEBA, SIEM and SOAR features into one platform. This means MSPs can consolidate tools and eliminate overlapping costs while improving detection quality.
How does Open XDR reduce alert fatigue?
Alert fatigue is one of the biggest challenges for MSPs. Analysts spend too much time triaging false positives instead of investigating real threats. Open XDR solves this with AI-driven correlation.
Instead of sending hundreds of raw alerts, Stellar Cyber automatically groups related events and presents high-confidence incidents. This reduces noise by up to 90 percent so analysts can focus on what matters.
What are the results of Open XDR for MSPs?
MSPs report measurable improvements across security outcomes, efficiency and revenue growth after adopting Open XDR:
Up to 8x better detection accuracy according to Stellar Cyber customer data
70 percent faster incident triage due to AI-driven correlation
90 percent reduction in alert noise
Multi-tool visibility in one place instead of constant tab switching
Lower cost to deliver SOC services at scale
This translates to stronger client trust, improved profitability per endpoint and scalable security revenue.
How does Open XDR support compliance reporting?
MSPs must prove value and demonstrate compliance progress for customers. Open XDR provides automated reporting aligned to frameworks like Cyber Essentials, ISO 27001, NIST CSF, SOC 2 and CIS Controls. Reports are generated per tenant and summarise detections, response actions, vulnerabilities, identity risks and security improvements over time. This allows MSPs to build trust through transparency.
How does Open XDR work in a multi-tenant environment?
In a multi-tenant environment, Open XDR provides:
Data isolation to meet compliance and security requirements
Per-tenant policy configuration
Cross-tenant analysis for threat trends
Shared playbooks for consistent response
One pane of glass for all customers
This enables MSPs to standardise security delivery across clients while still customising per environment where needed.
How does Open XDR support bring your own stack (BYOS)?
Unlike vendor-locked ecosystems, Open XDR empowers MSPs to choose the best tools for each client. If one prefers SentinelOne and another uses Sophos, Stellar Cyber integrates both in the same dashboard. This flexibility makes security services more attractive to MSPs who do not want to force customers to rip and replace existing investments.
Open XDR vs SIEM vs SOAR vs MDR: What is the difference?
Capability | EDR | SIEM | SOAR | Open XDR |
|---|---|---|---|---|
Endpoint visibility | Yes | No | No | Yes |
Log management | Limited | Yes | No | Yes |
Response automation | Limited | No | Yes | Yes |
Multi-vector correlation | No | Limited | No | Yes |
Threat hunting | Basic | Advanced | No | Advanced |
Multi-tenant | No | Varies | No | Yes |
Open XDR unifies EDR, SIEM, SOAR and threat hunting into one platform. It delivers more value than individual tools and simplifies operations.
How does Open XDR enable scalable MDR services for MSPs?
Open XDR is the foundation of MDR. It collects and analyses all security data to detect threats. With Stellar Cyber and enhanced.io, MSPs can offer 24×7 MDR under their own brand. This includes detection, triage, investigation and response support. MSPs scale faster without hiring additional analysts.
What does the Open XDR workflow look like?
Collect – data ingestion from firewalls, endpoints, SaaS and identity
Normalise – normalises logs and events to one schema
Correlate – uses AI correlation to connect events
Detect – detects multi-stage threats
Investigate – analysts gain full kill chain context
Respond – automated or guided response is triggered
Report – incident records and security evidence logged
How does Open XDR reduce operational cost for MSPs?
By consolidating tools and eliminating manual investigation, MSPs lower operating costs. One platform replaces multiple overlapping technologies. Automated detection and playbooks reduce time spent on tickets. Licensing is volume-based, which aligns with MSP billing models.
How does enhanced.io integrate Open XDR with SIEM, EDR, firewalls and IAM?
As part of the onboarding process enhanced.io deploys connectors for existing tool sets. For example:
Integration | Purpose | How it works |
|---|---|---|
SentinelOne | Endpoint telemetry | Alerts sent to Open XDR |
Microsoft 365 | SaaS email and identity logs | Data ingested and correlated |
Fortinet | Network traffic and firewall logs | See lateral movement |
Okta | Identity events | Detect MFA abuse |
No rip-and-replace. Everything works together.
Why do MSPs choose enhanced.io to manage Stellar Cyber?
Open XDR delivers unified security operations without forcing MSPs into vendor lock-in. Stellar Cyber powered by enhanced.io gives MSPs a fast path to MDR services with full stack visibility and 24×7 detection and response.
This means MSPs gain access to a fully operational and staffed SOC without needing to deploy analysts around the clock. The enhanced.io security team deploys, configures, integrates and manages the platform. Partners keep full visibility and control but do not have to build their own SOC infrastructure. MSPs gain a stronger security posture, happier customers and profitable recurring revenue.
