Soliton Systems Europe Secure Access for Auto vs OpenCloudFactory OpenNAC Enterprise: 2026 Comparison

Soliton Systems Europe Secure Access for Auto

Automotive suppliers and manufacturers operating on-premises networks will get the most from Secure Access for Auto because it combines remote access control with TISAX compliance built in, eliminating the compliance audit friction that normally comes with hybrid infrastructure. The on-premises application gateway handles encrypted network and app access while maintaining the air-gapped architecture many automotive OEMs require, and NIST PR.AA coverage confirms proper authentication enforcement across logical assets. This is not the tool for organizations needing cloud-first or cloud-only access; Soliton's strength is protecting legacy on-premises environments, not modernizing beyond them.

OpenCloudFactory OpenNAC Enterprise

Mid-market and enterprise security teams managing sprawling IoT and OT networks will see immediate value in OpenNAC Enterprise's Layer 2 device isolation tied to real-time threat detection, which stops compromised assets from moving laterally before detection even reaches your SOC. The platform covers PR.AA and DE.CM strongly, meaning it enforces access control at the network boundary and catches anomalies continuously, though it prioritizes prevention and detection over recovery orchestration. Skip this if your organization is primarily cloud-native or lacks the on-premises infrastructure to justify the deployment complexity; OpenNAC Enterprise is built for hybrid environments with significant legacy device populations that need granular segmentation without wholesale network redesign.
