What to Look for During Evaluation

When vetting these platforms for a large enterprise footprint, verify:

1. Deployment Flexibility: Can it run air-gapped or strictly inside your private VPC/Kubernetes cluster?
2. Referential Integrity: Does it maintain foreign key relationships across deeply nested relational schemas?
3. Auditability & Lineage: Can you log and trace every generated dataset back to its origin policy, user, and privacy parameter setting?dataversity.net+2

To help narrow down the right fit, could you share:

• What is your primary data structure (relational/tabular databases, unstructured text, or vector/LLM training data)?
• Do you require on-premises deployment , or is a private enterprise cloud (VPC) acceptable?

For a large enterprise where data governance, scalability, and strict control over sensitive data are non-negotiable, I would prioritize platforms that support controlled deployment, granular access policies, measurable privacy protection, and auditable data-generation workflows—not simply tools that produce realistic synthetic records.

My initial shortlist would be MOSTLY AI, Tonic.ai, Protegrity, NVIDIA NeMo (formerly Gretel), and Synthesized. Each addresses a somewhat different enterprise need, from privacy-preserving analytics to test-data management and centralized data protection.mostly.ai+4

How they compare on your priorities

This is a fit-based assessment, not a benchmark of independently tested products. Confirm specific controls, limits, and licensing with each vendor.

Sources: vendor documentation for MOSTLY AI, Tonic.ai, Protegrity, NVIDIA NeMo, and Synthesized.mostly.ai+4

The controls I would require before buying

For a strict enterprise environment, these requirements matter more than a vendor's overall ranking.

1. Verifiable privacy protection

Require membership-inference and record-reconstruction risk testing, privacy evaluation reports, and differential privacy where appropriate. Ask for formal privacy parameters when differential privacy is claimed.

---

2. Deployment and data residency

Determine whether training, generation, logs, temporary files, and backups can remain in your VPC or on-premises environment. Establish which external services, if any, receive data.

---

3. Granular governance

Require SSO, RBAC, separation of duties, dataset-level permissions, approval gates, audit logs, and configurable retention and deletion policies.

---

4. Enterprise scalability and reproducibility

Test generation on realistic data volumes, complex table relationships, concurrent users, and scheduled refreshes. Require versioned generators, reproducible runs, and documented quality checks.

---

5. Controlled data release

Require explicit approval before datasets can be exported or shared, with documented lineage, ownership, purpose, and privacy assessments.

One important distinction: synthetic data is not automatically anonymous or compliant. Realistic outputs can still reveal information about their source records. Treat privacy evaluation and release approval as mandatory controls, not optional extras.mostly.ai+6

My recommendation

I would begin with three vendor evaluations:

• MOSTLY AI for privacy-preserving synthetic datasets used across analytics and AI.
• Tonic.ai for production-like data in controlled development, testing, and AI workflows.
• Protegrity if centralized governance across the wider enterprise data estate is your dominant requirement.

Then bring in NVIDIA NeMo if AI training throughput is the primary workload, or Synthesized if complex relational test-data provisioning is the main problem.

Let’s narrow this to your environment

The best choice depends heavily on where the data must run and what you intend to generate. Which is your primary requirement?

1. Main workload

Analytics and AI training

Test data for software development

Both analytics/AI and test data

---

2. Deployment requirement

Vendor-hosted SaaS is acceptable

Private cloud / VPC

On-premises or air-gapped

Hybrid or multi-cloud

---

3. Governance environment

Financial services or highly regulated

Healthcare or life sciences

General enterprise / cross-industry

Government or critical infrastructure

---

4. Expected scale

Up to 10 million rows per dataset

10–100 million rows per dataset

100 million+ rows or enterprise-wide generation

Large text, document, image, or multimodal datasets

[Find the best-fit platforms]

I can use those answers to build a tighter shortlist with a weighted scorecard, deployment fit, privacy-control gaps, and the questions to put directly to each vendor during procurement.

For a large enterprise, I’d prioritize synthetic data platforms that combine horizontal scalability, deployment within your own cloud or data center, granular access controls, auditable workflows, and measurable privacy protection. The key is finding a tool that fits your data architecture and governance requirements—not just one that generates realistic records.

Enterprise comparison at a glance

Comparison based on vendor-published capabilities, not independent benchmark testing. “Self-managed deployment” and access-control availability depend on the particular product and plan.mostly.ai+3

What I would require before approving a vendor

For your emphasis on strict governance and scalability, I would make the following requirements part of the RFP and proof of concept.

1. Security and data governance

• SSO, MFA, RBAC, and integration with enterprise identity providers.
• Immutable or tamper-evident audit trails for data access, generation, export, and deletion.
• Data residency, encryption, key-management options, and restrictions on vendor access.
• Clear separation of development, staging, and production environments.

---

2. Proven scalability

• Demonstrated throughput at your actual target volume and concurrency.
• Horizontal scaling, workload scheduling, retries, and resource quotas.
• Support for large relational datasets and cross-table consistency.
• Predictable costs for recurring, automated generation jobs.

---

3. Measurable privacy protection

• Quantified privacy risk and testing for memorization or re-identification.
• Differential privacy where appropriate, including documented parameters and privacy-budget accounting.
• Utility and fidelity testing to ensure the data remains useful.
• Evidence supporting the organization's applicable regulatory obligations.

One important distinction: synthetic data is not automatically anonymous or compliant simply because it is artificially generated. Require documented privacy testing and approval by your privacy and security teams before releasing datasets.

My final recommendation

• Start with MOSTLY AI if you need an enterprise-wide synthetic data capability for analytics and machine learning.
• Prioritize Syntho if data residency and keeping processing inside your own environment are the dominant concerns.
• Prioritize Tonic.ai if your main bottleneck is provisioning realistic, production-like test data with strict access controls.
• Evaluate NVIDIA NeMo if the largest workload is synthetic data for LLMs, agents, or AI evaluation.

Before making a final selection, I would narrow the shortlist based on your architecture and the type of data you generate.

Important: These are capability-based recommendations, not results of an independent performance benchmark. Verify actual throughput, deployment limits, and contractual controls with each vendor.

2. Feature comparison

These ratings are qualitative assessments of documented capabilities, not independently measured scores.

3. Which platform wins for each requirement?

4. Critical enterprise governance requirements

Regardless of vendor, I would make the following capabilities mandatory in your procurement evaluation.

One important distinction: Synthetic data is not automatically anonymous. Require documented privacy testing and measurable privacy guarantees rather than accepting a vendor's general claim that its data is safe.

NVIDIA's documentation, for example, describes differential privacy through configurable privacy budgets and includes membership-inference and attribute-inference evaluation.docs.nvidia.com+2

5. My recommended shortlist

If I were running an enterprise procurement exercise, I would invite these three vendors to the initial proof of concept:

1. Tonic.ai – Benchmark its relational data generation, access controls, audit trails, and test-data workflows.
2. MOSTLY AI – Benchmark privacy protection, multi-table fidelity, and controlled deployment.
3. Betterdata – Benchmark air-gapped deployment, differential privacy, and dataset governance.

I would add NVIDIA NeMo if the organization has significant GPU infrastructure and its primary objective is AI training. Confirm its current production-support status and infrastructure requirements before committing; its Safe Synthesizer documentation specifies substantial GPU requirements.docs.nvidia.com+1

6. How I would evaluate them in a proof of concept

Use the same representative dataset for every vendor:

• A sensitive dataset containing customer, transaction, and account information.
• Multiple linked tables with foreign-key relationships.
• Personally identifiable and confidential attributes.
• At least one million records, with a larger scale test if production volumes require it.

Measure five things:

1. Performance: Generation throughput, concurrency, and processing time.
2. Privacy: Re-identification, membership inference, and attribute inference risk.
3. Fidelity: Statistical similarity and preservation of relationships.
4. Governance: Access restrictions, auditability, lineage, and approvals.
5. Operations: Deployment complexity, monitoring, cost, and integration effort.
