Context	Security & Privacy / Data Loss Prevention (DLP) Software	Security & Privacy / Data Loss Prevention (DLP) Software
Channel and data coverage	86The product spans direct API-based SaaS and email monitoring plus endpoint and browser enforcement, and it also covers GenAI interactions, but the facts do not establish coverage for every possible application or transport path.	81Tier 1 includes cloud applications and endpoints, while Tier 2 adds email to cloud applications and endpoints, and the product facts also reference collaboration, web uploads, and GenAI workflows, which gives broad channel coverage with tier-specific boundaries.
Detection and classification accuracy	87The product combines machine learning, OCR, computer vision, fingerprints, regex, dictionaries, and prompt-based detection, which gives it multiple detection methods for classification, though the facts do not provide measured accuracy results.	86Reduces identification errors by leveraging diverse inspection capabilities including OCR, exact data matching, and LLM classifiers, which must be tuned to prevent configuration-driven false rates.
Enforcement controls	87The product offers blocking, redaction, encryption, quarantine, access restriction, alerts, justification, and self-remediation, which gives buyers multiple control types, but some GenAI cases are qualified as monitor-only or manual-remediation.	83Block, redact, alert, guided-user, encryption, and incident-response controls are available where each channel supports them, enabling graduated responses rather than a single block-or-allow outcome.
Incident operations	82The product includes centralized policy administration, session evidence, Nyx-assisted investigation, and SIEM export, which supports incident operations, but the facts do not establish full workflow automation or case orchestration.	81Centralizes security alert management and search within a unified console, but security teams must allocate dedicated resources for continuous policy tuning and triage.
Governance and integrations	79The product includes direct API-based SaaS and email integrations and SIEM export, which supports governance and operational integration, but the facts do not establish broader ecosystem breadth or sync guarantees.	82Integrations with Microsoft, Okta, Splunk, ServiceNow, SIEM, SOAR, Teams, and native Proofpoint products, plus regional privacy controls, support enterprise identity, ticketing, and security-operations governance where those connectors are deployed.
User and risk context	77The product provides data lineage, session evidence, and justification, which helps connect actions to context and user behavior, but the facts do not establish a full identity-risk or behavior-risk model.	86Adaptive policies use user behavior, intent, activity, and risk scores, which gives the product a user-and-risk context layer that can inform DLP decisions beyond static content rules.
Support and total cost	55The product is sold by quote with no public numeric package price, payment schedule, or commitment term, and final price varies by package, application coverage, user count, and data volume, which makes total cost harder to pre-size.	50Both DLP Transform tiers require a custom quote with no published amounts, units, or service inclusions, and Advisory, Applied, managed, and professional services are marketed separately, so buyers cannot validate support scope or total cost without vendor engagement.
