Delphix vs K2view data masking, test data management, and synthetic data generation.

Independent comparison of Delphix vs K2view across data masking, test data management, and synthetic data generation

Intro to Delphix vs K2view 

Delphix and K2view each aim to accelerate software delivery by giving DevOps and QA teams faster access to compliant, reliable test data. Delphix delivers this through a virtualization tool that ingests production databases into a staging area, masks the data,  compresses it, and then presents virtual copies to lower environments.

K2view, on the other hand, uses a business entity approach that organizes data around customers, accounts, devices, or any logical business construct. Each entity’s data is continuously collected across operational systems and stored in secure, compressed micro-databases. This architectural model becomes the basis for its unified test data management, data masking, and synthetic data generation capabilities.

While Delphix is a good database virtualization tool for a defined list of supported technologies, K2view stands out as a high-performing enterprise-grade product with a 5/5 Gartner Peer Insights 12-month average rating – engineered for organizations with complex, distributed data landscapes, strict privacy mandates, and fast release cycles.

A recent Gartner Market Guide for Data Masking and Synthetic Data reinforces why a unified test data management, data masking, and synthetic data generationsynthetic data generation platform matters. Gartner notes that many static data masking tools “frequently lack advanced capabilities such as synthetic data generation or differential privacy, which are increasingly requested by end customers,” and specifically recommends that enterprises prioritize products that “include the creation of synthetic data, synthetic records, events or tabular synthetic data, as this can greatly speed up existing test data management processes.”

On the one hand, this recommendation aligns directly with K2view’s integrated approach – where masking, subsetting, and 4 types of synthetic data generation are built into the same engine that provisions test data. On the other hand, Delphix requires external tools for synthetic data generation and focuses primarily on virtualization, leaving critical privacy and test data management functions fragmented.

Delphix vs K2view comparison table

Let’s take a look at Delphix vs K2view over 13 different areas:

Area  Delphix K2view  K2view benefits
Core test data management approach
  • Virtualizes full databases from a staging area
  • Masks after ingestion
Uses a business entity approach that: 
  • Collects data from any source
  • Masks it in flight
  • Provisions it instantly
Fresher, safer test data, with far less infrastructure overhead
Data source coverage
  • Works with a defined list of supported databases
  • Adds new tech with difficulty
Connects to virtually any source: 
  • JDBC/ODBC,
  • APIs, and flat files
  • Cloud DWH, and NoSQL
Future-proof solution for hybrid, legacy, and cloud environments
Subsetting for test data management
  • Clones full datasets
  • Filters across multi-system data with difficulty
Maintains referential integrity via no-code entity rules across all systems Realistic, multi-source subsets without scripting
Moving test data between environments
  • Ties data to virtual DBs
  • Reproduces curated datasets, often requiring rebuilding
Provisions the same dataset to any environment in minutes Acceleration of defect reproduction and parallel testing
Per-tester reservation and rollback Requires separate environments or volume-level clones Features entity-level reservation and time travel for isolated tester workspaces Elimination of environment sprawl and tester collisions.
Near real-time test data Performs staging and masking cycles, but it often takes hours or even days Streams and masks fresh data in near real time Rapid issue reproduction under operational conditions
PII discovery and masking model Masks data after ingestion, leaving PII temporarily exposed Masks inflight, so PII is always protected Reduction of compliance exposure and privacy risk
Masking functions and extensibility
  • Good basic masking for structured data
  • Custom work needed for new formats
Dozens of configurable, reusable functions across structured, semi-structured, and unstructured data Acceleration of policy rollout and global compliance
Unstructured data masking Limited support Support for PDFs, images, documents, audio, and more Closure of a major enterprise privacy gap
Test data self-service Self-service at the database clone level Entity-level:
  • Subsetting
  • Reservation
  • Rollback
  • Aging
  • Refresh,
  • CI/CD integration
High-utility test data provisioned directly by the user
Synthetic data generation Limited support, for synthetic reference file data only Integrated synthetic data generation via 4 methods:
  • Rules
  • Cloning
  • Masking-based
  • GenAI
All testing needs covered, without additional tooling
Pricing and TCO
  • Priced by data volume and traffic
  • May require high-end infrastructure
Priced by number of sources, rather than size or usage Easier scaling and lower total cost
Role in the tooling landscape Good point tool for virtualization of supported databases Unified test data management, data masking, and synthetic data generation in one enterprise-class product Cross-company fit(where Delphix is departmental)

Key advantages of K2view

K2view offers a single solution integrating test data management, data masking, and synthetic data as recommended by Gartner. Here’s a quick overview of the 3 disciplines:

  1. Test data management

    K2view test data management tools are centered on the business entity model. Instead of stitching tables and schemas together manually, the solution automatically composes each customer, order, device, or policy from every relevant operational system. This abstraction hides complexity, significantly increasing adoption among developers and testers.

    Capabilities include:
    • A comprehensive, modular test data product combining sensitive data discovery, masking, subsetting, test data management strategy, self-service provisioning, and synthetic data generation in a single environment
    • Self-service provisioning that enables testers to subset, reserve, age, refresh, roll back, and load data in minutes
    • Integration with any system – packaged apps, mainframe, microservices, cloud warehouses, or legacy databases – allowing full test coverage

  2. Data masking

    K2view applies the business entity approach to data masking technology, enabling consistent and reliable masking across systems.

    Key advantages include:
    • In-flight data masking, so sensitive data is never exposed at rest
    • A broad catalog of customizable functions covering global data masking methods
    • Unified policies for structured, semi-structured, and unstructured content
    • A single masking framework powering test data management and synthetic data generation


  3. Synthetic data generation

    K2view integrates synthetic data generation directly into the test data lifecycle.

    Capabilities include:
    • End-to-end synthetic data generation lifecycle: Subset and mask training data, generate synthetic datasets, and orchestrate into pipelines
    • 4 synthetic data generation methods: Rules-based, cloning, masking-based synthesis, and GenAI
    • Entity-aware synthesis that maintains cross-system hierarchies






    The K2view unified test data management, data masking, and synthetic data generation solution supports: Snowflake data masking, Workday data masking, mainframe data masking, Oracle data masking, Salesforce data masking, and data masking tools for SQL Server – as well as SAP test data management tools – and more. 

Where Delphix is a good fit

Delphix is well suited to:

  • Small teams or departmental use
  • SMBs with straightforward relational databases
  • Data teams seeking a practical point tool for virtualization
  • Companies already invested in the Delphix ecosystem

Conclusion

When evaluating Delphix vs K2view, Delphix serves as a capable virtualization tool for supported databases. K2view, however, delivers a comprehensive enterprise-grade data product that unifies test data management, data masking, and synthetic data generation through its business entity approach.
