Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
CSS Antivirus for Managed File Transfers
Mid-market and enterprise teams transferring sensitive files through AWS Transfer Family need antivirus scanning that doesn't bottleneck large file ingestion, and CSS Antivirus for Managed File Transfers handles that by scanning in-flight without the performance penalties of bolt-on solutions. The tool covers NIST PR.DS and PR.PS across malware, ransomware, and data classification in one deployment, meaning you're not stitching together separate tools for detection and quarantine. Skip this if your file transfer volume is light or you're not standardized on AWS; the value equation breaks down outside heavy Transfer Family usage patterns.
Tectia SSH Server for IBM z/OS
Enterprise security teams managing mainframe data transfer pipelines need Tectia SSH Server for IBM z/OS because it's the only purpose-built SSH implementation that doesn't treat z/OS as an afterthought in your secure file transfer architecture. It covers both PR.DS (data security in transit) and PR.IR (infrastructure resilience) under NIST CSF 2.0, which matters because mainframe compliance audits actually check encryption logs at that level of specificity. Skip this if your organization is still centralizing all file transfer through x86-based gateways; Tectia only makes sense when you've committed to native mainframe security controls.
