Antivirus for Honeywell EPKS: McAfee vs. CrowdStrike
Introduction
Cybersecurity in industrial control systems is no longer optional. For users of Honeywell Experion PKS (EPKS), choosing the right antivirus software plays a big role in maintaining system uptime, data integrity, and compliance with ISA/IEC 62443 standards. Two leading players dominate this space in 2025: McAfee and CrowdStrike. In this blog post, we break down how each solution fits into the Honeywell EPKS environment.
As an electrical and automation professional with over many years in the field, I’ve deployed and supported both platforms across process plants, utilities, and chemical industries. Here’s a practical look at which antivirus solution works best for your critical control network.
Why Antivirus Matters in EPKS Systems
Honeywell EPKS systems control real-time operations. A virus outbreak can:
- Disrupt OPC/Modbus communications
- Corrupt control strategies and operator displays
- Force emergency shutdowns
- Cause long unplanned downtime
- Breach audit and compliance rules
A well-integrated antivirus protects:
- HMI/Operator stations
- Engineering workstations (EW, ES)
- Domain controllers and servers
- Historian and network appliances
Key Antivirus Requirements for EPKS
| Requirement | Why It Matters |
|---|---|
| Low system resource usage | Avoid performance issues on control nodes |
| Offline update capability | EPKS networks are often air-gapped |
| Whitelisting support | Prevent blocking critical Honeywell services |
| Vendor certification | Must be tested with Honeywell software |
| Real-time threat monitoring | Essential for detecting zero-day attacks |
| Centralized management | Control deployment across 100+ nodes |

Which Antivirus Is Better for Honeywell EPKS?
🟢 Choose McAfee If:
- Your site is isolated from the internet
- You are using older versions of Honeywell EPKS
- You need proven compatibility and support
🟢 Choose CrowdStrike If:
- You need real-time protection
- Your plant integrates with IT systems and remote monitoring
- You are upgrading or starting a new EPKS project
Expert Tips Before Deploying Antivirus in EPKS
- Check Honeywell Compatibility Matrix
- Always verify antivirus versions approved for your specific EPKS release
- Test in a Lab Environment First
- Validate updates and performance before production deployment
- Create Exclusions
- Whitelist EPKS file paths and services to avoid system disruptions
- Use Scheduled Scans
- Run scans during off-peak hours to avoid CPU spikes
- Log Everything
- Integrate AV logs with OT monitoring tools for full visibility
Conclusion
Both McAfee and CrowdStrike offer strong protection for Honeywell EPKS systems in 2025. McAfee provides solid baseline defense for air-gapped legacy setups, while CrowdStrike leads in intelligent cloud-based detection for modern hybrid architectures.
Make your decision based on system version, network structure, update policies, and future expansion plans. With the right setup, your antivirus won’t just protect it’ll enhance control system resilience.
