The IRI Voracity Data Management platform and the <\/span>IRI Data Protector<\/span><\/a> suite provide robust data masking tools for finding and anonymizing sensitive data in different environments. When working with relational database (RDB) sources, however, two key IRI products come into play: <\/span>FieldShield<\/span><\/a> and <\/span>DarkShield<\/span><\/a>. <\/span><\/p>\n

Both tools have the same pricing for RDB use and share the same front-end IRI Workbench GUI<\/a>. Both also use the same data classes<\/a> and masking functions<\/a> to secure personally identifiable information (PII) and other sensitive data in database environments. However, they differ somewhat in functional scope, discovery capabilities, runtime engines, and job configurations.<\/span><\/p>\n

Functional Comparison Matrix<\/b><\/h2>\n

The following overview highlights the key differences between FieldShield and DarkShield.<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n
Feature\/Aspect<\/b><\/span><\/td>\nFieldShield<\/b><\/span><\/td>\nDarkShield<\/b><\/span><\/td>\n<\/tr>\n
Primary Focus<\/b><\/td>\nStructured data masking in relational databases<\/span><\/td>\nDiscovery and masking across structured <\/span>and<\/span><\/i> semi\/unstructured RDB columns<\/span><\/td>\n<\/tr>\n
Data Types Supported<\/b><\/td>\nStrictly structured fields (tables, columns)<\/span><\/td>\nStructured fields plus<\/em> semi\/unstructured text or files in RDB columns<\/span><\/td>\n<\/tr>\n
Discovery Capabilities<\/b><\/td>\nData classification<\/span><\/a> (search) is performed before<\/em> masking, though it uses the same data classes and masking rules as DarkShield. Limited to metadata (location-based) matchers for discovery.<\/span><\/td>\nSimultaneous<\/em> search and masking of sensitive data in a schema using the same data classes and <\/span>masking functions<\/span><\/a> as FieldShield. <\/span>Uses location and\/or data (content) matchers as needed.<\/span><\/td>\n<\/tr>\n
Masking Methods<\/b><\/td>\nDeterministic, encryption, pseudonymization, redaction, etc.<\/span><\/td>\nSame masking methods, extended to free-text and mixed data formats<\/span><\/td>\n<\/tr>\n
Integration<\/b><\/td>\nDeep integration with Voracity ETL via the use of the CoSort <\/span>SortCL<\/span><\/a> syntax and program for its masking jobs<\/span><\/td>\nSupported in Voracity, can create\u00a0 SortCL DDF for <\/span>textual ETL<\/span><\/a> use, but uses a REST API<\/a> for search\/mask<\/span><\/td>\n<\/tr>\n
Ease of Use<\/b><\/td>\nRequires schema knowledge and more setup steps<\/a><\/span><\/td>\nWizard-driven GUI<\/a> in IRI Workbench for RDB masking jobs (search + mask simultaneously)<\/span><\/td>\n<\/tr>\n
Audit & Logging<\/b><\/td>\nProduces an audit trail of search results and masking job details; integrates with CoSort V11<\/a> OGS logging<\/span><\/td>\nEnhanced audit logs for discovery and masking jobs across mixed RDB columns<\/span><\/td>\n<\/tr>\n
Best Fit<\/b><\/td>\nStructured relational database environments with well-defined schemas<\/span><\/td>\nHybrid environments where sensitive data may reside in both structured and semi\/unstructured RDB columns<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
