CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
SMBs and mid-market teams drowning in file-based malware will find Resec's appeal in its CDR approach, which strips threats from documents without blocking them outright. The platform processes hundreds of file types including password-protected and multi-layer encrypted attachments in real time, with zero false negatives claimed across Exchange, Office 365, and Gmail. Skip this if you need behavior-based detection or threat hunting; Resec is file sanitization only, and it won't help you investigate what was actually in that malicious Word doc.
MSPs and mid-market IT teams managing multiple customer tenants will get immediate value from Mesh Gateway's cross-tenancy visibility and standardized policy templates, which eliminate the friction of deploying email security across disparate customer environments. The 15-minute MX record deployment and native integrations with Microsoft 365 and Google Workspace mean you're protecting inboxes before the end of a sales call, and DMARC/DKIM/SPF verification handles sender authentication without requiring customers to rebuild their email infrastructure. Skip this if you need post-breach forensics or detailed incident response workflows; Mesh Gateway prioritizes detection and quarantine over investigation depth, with no meaningful coverage in NIST Recover functions.
