Mirato TPRM Intelligence Platform vs Whistic Platform: Side-by-Side Comparison (2026)

Mirato TPRM Intelligence Platform

Mid-market and enterprise security teams drowning in vendor questionnaires should start with Mirato TPRM Intelligence Platform; its Questionnaire Killer feature cuts assessment cycles from weeks to days by automating the repetitive intake work that eats your team's time. The platform maps directly to NIST CSF 2.0's GV.SC supply chain risk processes and ID.RA risk assessment requirements, which matters if you're auditing vendor controls at scale. Skip this if you need deep incident response integration or real-time threat intelligence feeds; Mirato is strong on the assessment and evaluation side, weaker on continuous monitoring and breach alerting once a vendor is already in your environment.

Whistic Platform

Mid-market and enterprise security teams drowning in vendor questionnaires will see immediate ROI from Whistic Platform; its AI automatically fills responses using your own documentation, cutting assessment cycles from weeks to days. The platform maps responses across 40+ frameworks simultaneously and maintains a network of pre-vetted vendors, so you're not starting from zero on every new third-party. Skip this if your vendor base is under 20 or if you need real-time continuous monitoring of live vendor infrastructure; Whistic excels at intake and onboarding, not runtime risk detection.
