Invary for CIS vs RTS Secure Boot Loader: Side-by-Side Comparison (2026)

Invary for CIS

SMB and mid-market teams that need to verify their OS and hardware haven't been tampered with will find Invary for CIS valuable; the NSA-licensed core technology and dual deployment options (cloud and on-premise) give you flexibility without sacrificing integrity measurement across the stack. NIST CSF 2.0 coverage is strongest in Platform Security and Continuous Monitoring, the two functions that matter most for detecting rootkits and firmware attacks. Skip this if you're looking for a full endpoint protection platform with threat response; Invary is purpose-built for integrity verification, not incident hunting.

RTS Secure Boot Loader

Startup and SMB security teams protecting Windows and Linux endpoints from pre-OS attacks will find real value in RTS Secure Boot Loader's firmware-level signature verification, which stops malware before the kernel loads. The tool handles EFI Secure Boot enforcement across native Windows, Ubuntu, and Debian without requiring hypervisor overhead, addressing the NIST PR.PS platform security control directly at boot time. Skip this if you need runtime behavioral detection or threat hunting; RTS is a prevention-only gate, not a post-compromise investigative tool.
