Vanguard Integrity Professionals vs VaultOne: Side-by-Side Comparison (2026)

Vanguard Integrity Professionals

Enterprise and mid-market security teams defending z/OS mainframes should use Vanguard Integrity Professionals because it's the only PAM tool built specifically for RACF, ACF2, and Top Secret environments where generic solutions simply don't work. The platform covers six NIST CSF 2.0 functions including continuous monitoring and access control enforcement, with integrated vulnerability analysis via z/Assure VAP that catches mainframe-specific exposures. Skip this if your mainframe team is small or your organization treats legacy systems as non-critical; Vanguard requires the infrastructure and staffing typical of large financial services and government shops where mainframe security actually matters to compliance auditors.

VaultOne

Mid-market and smaller enterprise teams managing hybrid infrastructure will see immediate value in VaultOne's session recording and credential vault, which closes the visibility gap that kills most PAM deployments. The tool covers NIST PR.AA and DE.CM, meaning you get both access control enforcement and the continuous monitoring needed to catch lateral movement using stolen admin accounts. Skip this if you need enterprise-scale orchestration across thousands of endpoints or a vendor with deep SOC2 audit history; VaultOne's five-person team means slower feature velocity and less battle-tested incident response playbooks than market leaders.
