How we chose the best SASE providers for industrial firms

Industrial environments aren't like typical office networks. Your plant floor runs equipment that can't be patched during production, and a misconfigured security rule could halt an entire line. We looked at providers that understand these realities—not just on paper, but in how they deploy and support their solutions.

• OT/IT convergence support: Does the platform handle both corporate traffic and industrial control system communications without creating blind spots?
• Zero trust architecture: Can you segment access by user, device, and application—especially for third-party vendors who need remote access to equipment?
• 24/7 SOC capabilities: Manufacturing runs around the clock, so your security monitoring should too. We prioritized providers with always-on threat detection.
• Compliance alignment: Industrial firms often face CMMC, NIST, or industry-specific requirements. The right SASE provider helps you meet these without extra overhead.
• MSSP delivery model: Not every plant has a dedicated security team. We considered how well each provider supports managed service delivery.
• US presence and support: Data residency and response times matter. Providers with domestic points of presence and support got higher marks.

The best SASE providers for US industrial firms

What does SASE mean for OT and IT convergence in manufacturing?

SASE (Secure Access Service Edge) brings networking and security together in a cloud-delivered model. For manufacturing, this matters because your plant floor systems and corporate IT increasingly share the same infrastructure.

Traditional approaches kept OT networks air-gapped from IT systems. That isolation is disappearing as manufacturers adopt real-time monitoring, predictive maintenance, and remote vendor access. SASE platforms help you secure these connections by applying consistent policies across all traffic—whether it's a finance team member accessing cloud applications or a technician connecting to a PLC.

The challenge is finding a SASE provider that understands industrial protocols and environments. Generic solutions may not recognize SCADA traffic patterns or know how to segment access for equipment vendors without disrupting production.

How can industrial firms evaluate SASE providers for compliance needs?

Start by listing which frameworks apply to your operations—CMMC for defense contractors, HIPAA if you handle medical device manufacturing, NIST for general cybersecurity hygiene. Then ask potential providers how their platform maps to those requirements.

Look for providers who go beyond checkbox compliance. The right partner should help you document controls, prepare for audits, and close gaps before they become findings. Ask about ongoing assessment services and whether they'll participate in audit interviews if needed.

• Request evidence of their own security certifications (SOC 2, ISO 27001)
• Ask how they handle data residency for regulated information
• Confirm their incident response process aligns with your reporting requirements
• Verify they can segment and monitor traffic to meet framework-specific controls

FAQs about SASE providers for US industrial firms

What is SASE and why does it matter for manufacturing?

SASE combines networking and security into a single cloud-delivered service. For manufacturing, this simplifies protecting both corporate IT and plant floor OT systems under one framework.

Securafy delivers SASE capabilities with industrial-sector expertise, helping manufacturers secure converged environments without the complexity of managing multiple point solutions.

How does SASE handle remote vendor access to factory equipment?

SASE platforms use zero trust principles to grant vendors access only to specific equipment—not your entire network. Sessions are monitored and logged for audit purposes.

Securafy configures these access controls based on your vendor relationships, ensuring technicians can service equipment while keeping production systems isolated from broader exposure.

Can SASE protect legacy industrial control systems?

Yes, but implementation matters. Older ICS equipment wasn't designed for modern network security, so your SASE provider needs to understand industrial protocols and segment traffic appropriately.

Securafy works with manufacturers who rely on legacy PLCs and SCADA systems, applying network segmentation and monitoring that protects these assets without disrupting operations.

What compliance frameworks do SASE providers support for industrial firms?

Common frameworks include NIST Cybersecurity Framework, CMMC for defense contractors, and industry-specific standards like IEC 62443 for industrial automation. HIPAA and PCI may also apply depending on your operations.

Securafy offers Compliance as a Service (CaaS) covering CMMC, NIST, HIPAA, PCI, SOX, and other frameworks relevant to US industrial companies.

How quickly can a SASE solution be deployed in a manufacturing environment?

Deployment timelines vary based on the complexity of your environment and the provider's approach. Some cloud-native platforms can start protecting traffic in days, while full OT integration may take weeks.

Securafy begins every engagement with a third-party network assessment to understand your current state before designing a deployment plan that minimizes production impact.
