Email keeps your entire manufacturing supply chain moving. Every day you’re coordinating with global suppliers, managing million-dollar purchase orders, sharing engineering specs, negotiating contracts, and orchestrating just-in-time delivery schedules. One compromised email can redirect payments, leak designs, or shut down production.

Your infrastructure ties together procurement, engineering, sales, logistics, and finance—each sending critical information across borders and between facilities. Every one of those connections becomes a target if email authentication isn’t locked down.

IT and security teams in manufacturing manage high-value transactions, protect intellectual property, support multiple plants and international offices, and often work around legacy systems that are difficult (if not impossible) to modernize.

Manufacturers need email authentication that protects supply chain communications, prevents business email compromise, and works reliably across complex global operations.

Manufacturing email security challenges

• Business email compromise: Cybercriminals impersonate suppliers requesting payments, fake executives approving wire transfers, or spoof logistics partners changing shipping details.
• Supply chain surfaces: Every supplier, vendor, and partner you work with is a potential entry point. If attackers can’t breach your systems directly, they’ll compromise a supplier.
• High-value transactions: When major financial transactions happen over email without proper authentication, you’re always vulnerable to fraud.
• Global operations: Manufacturing companies operate across countries and time zones, each with different email systems, security standards, and IT infrastructure.
• Production pressure: Manufacturing can’t afford email disruptions. Production schedules, shipment notifications, and quality alerts need to flow reliably.
• Vendor security: Your large suppliers might have robust security, but smaller contractors often don’t. One compromised vendor can become a launching point for attacks.

IP protection	Document encryption, access controls	Domain authentication prevents spoofing
Production continuity	Risk of email disruptions during changes	Zero-downtime implementation
Vendor ecosystem	Tracking spreadsheets for authorized senders	Automated identification and authorization

• Prevent BEC attacks: DMARC enforcement prevents attackers from impersonation. Fraudulent payment redirects and spoofed purchase orders get blocked before they reach inboxes.
• Protect communications: Authenticate every email claiming to be from your domain so suppliers, vendors, and partners know legitimate communications from your company are actually from you.
• Secure financial transactions: When procurement sends a purchase order or finance initiates a wire transfer, recipients can verify that the email is legitimate.
• Safeguard intellectual property: Prevent attackers from using spoofed emails to request engineering specifications, manufacturing processes, or proprietary designs from your teams.
• Centralized control: Manage authentication from anywhere in the world across all your facilities, regions, and business units with a single platform.
• Reliable integrations: Valimail integrates with your current email infrastructure, ERP systems, and supplier portals without requiring wholesale replacements or production disruptions.
• Vendor visibility: Identify every third-party service sending email on behalf of your manufacturing operations, whether that’s logistics providers or quality certification bodies.

Valimail Enforce protects manufacturing companies from email-based attacks targeting supply chains and high-value transactions.

Common manufacturing questions

How does DMARC prevent business email compromise in manufacturing?

DMARC prevents attackers from spoofing your domain to send fraudulent emails. This blocks the impersonation attacks used in BEC—fake supplier payment redirects, spoofed executive requests, fraudulent purchase orders. With DMARC at enforcement, these emails never reach their targets.

Will DMARC implementation disrupt our supply chain communications?

No. Valimail’s implementation process guarantees zero disruption to critical supply chain emails. We start with monitoring to identify all legitimate senders, authorize them, and then move to enforcement only when we’re certain legitimate communications won’t be affected.

How do we manage authentication across multiple manufacturing facilities?

Valimail provides centralized visibility and control across all your facilities, regions, and business units. Set global policies while maintaining flexibility for facility-specific sending services. Manage everything from a single platform regardless of where your facilities are located.

What about our suppliers’ email security?

DMARC protects your domain by preventing attackers from spoofing emails that appear to come from your company. While you can’t control supplier security, protecting your own domain prevents attackers from impersonating you to target suppliers or using your domain to launch attacks.

Can Valimail work with our ERP and supply chain systems?

Yes. Valimail integrates with existing manufacturing infrastructure, including ERP systems, supplier portals, and logistics platforms that send email on your behalf. We identify these systems and help you authorize them properly.

How does this protect our intellectual property?

DMARC prevents attackers from spoofing your domain to request sensitive engineering specifications, designs, or manufacturing processes from your teams. It won’t prevent all IP theft, but it closes a common attack vector.

What happens during mergers or acquisitions?

Valimail helps you quickly evaluate the authentication posture of acquired companies, integrate their domains under your security policies, and maintain visibility across the combined organization. This matters for maintaining supply chain security during transitions.

How long does implementation take for global operations?

Most manufacturing companies reach enforcement in 45-90 days (depending on the complexity of global operations). Our phased approach lets you start with primary domains and expand to regional facilities and business units systematically.
