Fortra ZTNA vs Soliton Systems Europe Secure Access for Auto: Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise teams replacing VPN will find Fortra ZTNA's strongest value in its hybrid deployment flexibility and granular access controls that actually enforce least-privilege without admin headaches. The platform covers all four critical NIST CSF 2.0 areas for identity and continuous monitoring, which matters because most ZTNA products punt on asset inventory or detection tuning. Skip this if your org needs deep integration with legacy on-premises identity systems or runs exclusively on-prem; Fortra's strength is in hybrid environments where cloud and datacenter access requirements overlap. 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.
