Acuity Risk Management STREAM® vs Bastion: Side-by-Side Comparison (2026)

Acuity Risk Management STREAM®

Mid-market and enterprise security teams drowning in compliance checkbox work should seriously consider Acuity Risk Management STREAM® because it actually automates evidence collection across 50+ frameworks instead of just templating them. The platform covers 8 of 8 NIST CSF 2.0 Govern function areas, including the often-neglected supply chain risk management piece, and its continuous controls monitoring with security tool integrations means you stop running manual audit prep sprints every quarter. Skip this if your organization has zero appetite for configuration work; the no-code flexibility that makes STREAM adaptable to your specific regulatory mix requires someone to actually do that adaptation.

Bastion

Scaling startups and SMBs that need compliance evidence collection without hiring a full security team should pick Bastion for its automated control validation and dedicated vCISO support. The platform covers SOC 2, ISO 27001, GDPR, and HIPAA simultaneously with continuous monitoring, meaning you're not manually assembling audit packs month-to-month. Skip this if you need mature detection and response capabilities; Bastion prioritizes governance and vendor risk management over security operations, leaving gaps in the Detect and Respond functions of NIST CSF 2.0.
