CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Enterprise and mid-market teams already invested in Microsoft 365 should buy Microsoft Purview for data classification and DLP enforcement without the integration tax that standalone tools carry. It covers NIST PR.DS and DE.CM simultaneously, giving you labeling, discovery, and policy enforcement across email, cloud apps, and devices from one console. Skip this if your organization runs on Google Workspace or has minimal Microsoft infrastructure; the product assumes M365 as your data backbone, and retrofitting it elsewhere creates friction that negates the convenience argument.
Mid-market and enterprise security teams bleeding data through cloud APIs and employee endpoints need OrionSec Security; it stops exfiltration before it leaves your environment, which most DLP tools only log after the fact. The 99.9% uptime commitment and 24/7 alerting backed by SOC 2 certification mean you're not gambling on availability when your data is the asset being protected. Skip this if your primary concern is insider threat investigation or forensics; OrionSec is prevention-first, not built to help you reconstruct what happened after the breach.
