Quick Answer
The best cross-platform EDR platforms provide consistent endpoint detection and response across Windows, macOS, and Linux.
That means having comparable:
- Endpoint telemetry
- Behavioral detection
- Investigation capabilities
- Automated response
- Policy management
- Security operations workflows
When evaluating EDR platforms, focus on four criteria:
- OS coverage and feature parity
- Detection quality
- Response workflows
- Platform fit
Leading options include:
- CrowdStrike Falcon
- SentinelOne Singularity
- Microsoft Defender for Endpoint
- Palo Alto Networks Cortex XDR
- Sophos
- Trend Micro
- Bitdefender
- Elastic Security
- Seceon aiXDR-PMax
Seceon differentiates its endpoint approach by combining EDR, EPP, DLP, and file integrity monitoring (FIM) in one lightweight agent that feeds a unified SIEM, NDR, UEBA, and SOAR platform.
What Is Cross-Platform EDR?
Cross-platform EDR is endpoint detection and response that protects Windows, macOS, and Linux endpoints and servers with consistent monitoring, detection, investigation, and response capabilities from a single management console and policy framework.
A true cross-platform EDR platform provides:
- One agent family across operating systems, with a consistent policy model
- Comparable telemetry on each OS, including processes, files, network connections, users, and scripts
- Behavioral detection tuned to each operating system's attack techniques
- Equivalent response actions across platforms, including isolation, process termination, and evidence collection
- One console for investigation instead of separate tools for each OS
The key word is consistent. Supporting an operating system and protecting it equally well are not the same thing.
Why OS Parity Matters: Threats Differ by Platform
Each operating system has its own attack surface. Your EDR needs to detect the techniques that matter on each platform.
| Operating System | Common Threats | Telemetry an EDR Must Capture |
|---|---|---|
| Windows | Ransomware, living-off-the-land binaries, PowerShell abuse, credential dumping, registry persistence | Process trees with command lines, script execution, registry changes, memory injection, authentication events |
| macOS | Infostealers, malicious launch agents and daemons, login-item persistence, TCC abuse, supply-chain attacks on developer tools | Process and file activity, persistence locations, script execution, network connections, unified logging |
| Linux | Cryptominers, web shells, SSH brute force and key abuse, privilege escalation, container escape, cloud credential theft | Process execution, file integrity on critical paths, network sockets, user and sudo activity, container context |
Linux gaps can be particularly costly because Linux commonly runs the servers, databases, and cloud workloads that hold critical organizational data.
Four Criteria for Comparing Cross-Platform EDR Platforms
1. Coverage and Feature Parity
Confirm supported:
- OS versions
- Linux distributions
- Kernel versions
- Legacy servers
Then check feature parity.
Ask:
Does every detection and response capability available on Windows also work on macOS and Linux?
Supporting all three operating systems is not enough if critical security functionality is only available on one of them.
2. Detection Quality
Look for behavioral detection that can identify unknown threats without relying entirely on signatures.
Important capabilities include:
- Fileless malware detection
- Memory injection detection
- Credential theft detection
- Process-chain analysis
- Behavioral analysis
- MITRE ATT&CK mapping
Also evaluate false-positive rates in your own environment.
3. Response Workflows
Check which response actions are available on each operating system:
- Network isolation
- Process termination
- File quarantine
- Hash blocking
- Forensic evidence collection
Also determine whether automated response is available through native playbooks or requires a separate SOAR product.
4. Platform Fit
Evaluate:
- Agent footprint
- CPU and memory usage
- MDM support
- Configuration-management integrations
- Cloud-native deployment
- SIEM integrations
- Identity integrations
- Multi-tenancy
- Per-tenant policy management
For MSSPs, multi-tenancy can be especially important because endpoint security may need to be managed across hundreds of customer environments.
Cross-Platform EDR Evaluation Matrix
| Criterion | What "Good" Looks Like | Questions to Ask Vendors |
|---|---|---|
| OS coverage | Windows, macOS, and major Linux distributions, including server editions | Which OS versions, distros, and kernels are supported today? |
| Feature parity | The same detection and response capabilities on every OS | Which features are Windows-only? |
| Detection quality | Behavioral, memory, and script-based detection mapped to MITRE ATT&CK | How many detections work without custom rules on macOS and Linux? |
| Response automation | Isolation, kill, quarantine, and block automated via playbooks | Is automated response native or a separate license? |
| Agent footprint | Low CPU and memory impact on production servers | What is idle and active CPU use on a Linux database server? |
| Correlation | Endpoint telemetry correlated with network, identity, and cloud data | Does endpoint data correlate natively with SIEM and NDR? |
| MSSP readiness | Multi-tenant console, tenant isolation, and per-tenant policies | Can one console manage hundreds of customer tenants? |

A Note on Independent Testing
Independent evaluations can be useful inputs when evaluating EDR platforms.
However, published evaluations may not cover every vendor or every environment. Several major EDR vendors did not participate in the 2025 MITRE ATT&CK Evaluations: Enterprise.
For that reason, organizations should test candidate platforms against their own combination of:
- Windows systems
- macOS systems
- Linux servers
- Cloud workloads
- Production applications
- Existing security infrastructure
Standalone EDR vs. EDR Inside a Unified Platform
| Dimension | Standalone EDR | EDR Inside a Unified Platform |
|---|---|---|
| Visibility | Endpoint-focused | Endpoint plus network, identity, cloud, and OT |
| Attack reconstruction | Endpoint chain | Full cross-domain attack chain |
| Lateral movement detection | Endpoint signals only | Endpoint plus network flow (NDR) and UEBA |
| Automated response | Endpoint actions | Endpoint, firewall, identity, and cloud actions |
| Data protection | Often separate DLP and FIM tools | DLP and FIM in the same agent |
| Consoles | EDR console plus SIEM and SOAR | One console |
A standalone EDR can make sense when an organization already operates a mature SIEM and SOAR stack and has the engineering capacity to integrate them.
For teams looking to reduce the number of security tools and simplify multiplatform security operations, EDR inside a unified platform can reduce integration requirements.
How Seceon aiXDR-PMax Delivers Cross-Platform Endpoint Detection and Response
Seceon aiXDR-PMax is the endpoint layer of the Seceon Open Threat Management (OTM) Platform.
It provides:
- EDR
- Endpoint Protection (EPP)
- Data Loss Prevention (DLP)
- File Integrity Monitoring (FIM)
These capabilities are delivered through a single lightweight agent managed from the same console as:
- aiSIEM
- NDR
- UEBA
- SOAR
One Agent Across Windows, macOS, and Linux
The aiXDR-PMax agent supports:
- Windows 10/11
- Windows Server 2008 and later
- macOS 12 and later

The agent uses under 50 MB installed and under 1% CPU when idle, allowing it to run on production servers.
Behavioral Detection From Day One
Detection is behavioral rather than signature-dependent.
Memory forensics and process-chain analysis can detect:
- Fileless malware
- Process injection
- Code hollowing
- Credential dumping
Ransomware pre-encryption behavior can trigger alerts before files are lost.
Endpoint Data That Correlates With Everything Else
Endpoint telemetry is normalized into the Seceon Event Format and correlates natively with aiSIEM, NDR, and UEBA data.
For example, a:
- Suspicious process on a Linux server
- Unusual east-west network connection
- Anomalous user login
can become a single prioritized incident with full attack-chain reconstruction.
This cross-domain correlation provides security teams with broader context than endpoint telemetry alone.
Automated Response on Every OS
Native SOAR can execute:
- Endpoint isolation
- Process termination
- Hash blocking
- Evidence collection
The platform provides sub-90-second automated response, with approximately 70% of incident response automated.
Built-In DLP and File Integrity Monitoring
The same agent monitors sensitive data movement involving:
- PII
- PHI
- PCI data
- Credentials
It also tracks file creation, modification, and deletion on critical paths across Windows, Linux, and macOS.
FIM provides compliance evidence for frameworks and standards including:
- PCI DSS
- HIPAA
- SOX
- NIST
- CERT-In
Forensics and Threat Hunting
aiXDR-PMax supports IOC-based and YARA rule-based scanning across:
- Windows
- Linux
- macOS
Scanning can run in:
- Real-time mode
- Scheduled mode
Evidence artifacts are hashed using SHA-256 at acquisition to help preserve chain of custody.
Cloud-Native Deployment
Agents can be deployed through:
- AWS Systems Manager
- Azure VM Extensions
- Google Cloud OS Config
- Kubernetes DaemonSets
- Chef
- Puppet
- Ansible
This allows organizations to integrate endpoint deployment into existing infrastructure-management workflows.
Works With Your Existing EDR
Already running:
- CrowdStrike
- SentinelOne
- Carbon Black
- Microsoft Defender
Seceon can ingest and correlate telemetry from existing EDR platforms through integration mode.
This allows organizations to add cross-domain detection and automated response without immediately replacing their existing endpoint security platform.
MSSP-Ready Multi-Tenancy
Seceon's multi-tenant, multi-tier architecture allows MSSPs to manage endpoint security for multiple customers from a single console.

Which Cross-Platform EDR Should You Choose?
The right architecture depends on your existing security stack, operating-system mix, operational requirements, and integration strategy.
A Standalone EDR may fit if:
- You already run a mature, well-integrated SIEM and SOAR stack
- Your team has deep detection-engineering capacity
- You are standardized on one security vendor's ecosystem
Seceon aiXDR-PMax may fit if:
- You want endpoint, network, identity, and cloud detection in one platform
- You need DLP and FIM without adding additional agents
- You operate a mixed Windows, macOS, and Linux environment
- You operate in regulated or sovereign environments
- You deliver managed endpoint security as an MSSP
Final Takeaway
Cross-platform EDR is not simply about whether a vendor has an agent for Windows, macOS, and Linux.
The more important question is:
How consistent are detection, telemetry, investigation, and response capabilities across those operating systems?
When evaluating an EDR platform, validate OS coverage, feature parity, detection quality, response automation, agent performance, integrations, and multi-tenancy against your actual environment.
For organizations looking beyond endpoint-only protection, a unified architecture can connect endpoint telemetry with network, identity, cloud, and other security signals, providing a broader foundation for detection and response.
