KMS/Vault vs Ubiq

Executive Summary

Key Management Systems, or KMS, and Vault platforms provide critical infrastructure for managing cryptographic keys, secrets, certificates, and cryptographic operations. Examples include AWS KMS, Azure Key Vault, Google Cloud KMS, HashiCorp Vault, cloud HSM services, and enterprise key management platforms.

These controls are valuable and should remain part of the architecture.

KMS and Vault systems address important parts of the security model. They help teams create, store, rotate, protect, audit, and use keys and secrets. They can support envelope encryption, application secrets, certificate management, signing, HSM-backed key storage, and encryption-as-a-service patterns.

Ubiq addresses a different layer of the problem: protecting sensitive data values themselves and governing whether users, applications, service accounts, APIs, pipelines, BI tools, AI workflows, and downstream systems can access those values in cleartext at runtime.

The strongest model is layered. Use KMS and Vault systems for key management, secrets management, cryptographic operations, and HSM-backed trust. Use Ubiq for identity-aware runtime protection of sensitive fields and records across applications, databases, warehouses, APIs, BI tools, AI workflows, and downstream systems.

Key Takeaways

KMS/Vault systems and Ubiq runtime sensitive data protection solve different problems and should be viewed as complementary controls.
KMS and Vault platforms are strong for managing keys, secrets, certificates, cryptographic operations, HSM-backed controls, and auditability.
Ubiq protects selected sensitive values directly and controls whether an identity or workflow can access those values in cleartext at runtime.
KMS and Vault systems help protect and use cryptographic keys. Ubiq applies data protection and runtime policy enforcement to sensitive fields and records.
Ubiq is especially useful when organizations need to reduce cleartext exposure across applications, service accounts, APIs, pipelines, databases, warehouses, BI tools, AI/RAG workflows, exports, and downstream systems.

Where KMS and Vault Systems Help

KMS and Vault systems provide foundational capabilities for cryptographic key and secret management.

These controls help teams:

Create and manage cryptographic keys
Store and rotate secrets
Manage certificates
Protect keys with hardware security modules or HSM-backed services
Support envelope encryption patterns
Encrypt and decrypt data keys
Provide signing and verification operations
Provide encryption-as-a-service through APIs
Centralize key and secret access policies
Audit key and secret usage
Integrate with cloud services, applications, databases, and infrastructure
Support bring-your-own-key and customer-managed-key patterns
Reduce hardcoded secrets and unmanaged keys

These capabilities are valuable for enterprise security.

They help answer questions such as:

Where are cryptographic keys stored?
Who can use a key?
Which systems can access secrets?
How are keys rotated?
How are keys protected by HSMs?
Which applications used a key or secret?
How are application credentials managed?
How are cloud services integrated with customer-managed keys?

For many environments, KMS and Vault systems are essential.

However, they primarily manage cryptographic keys, secrets, and operations. They do not, by themselves, define a complete runtime model for protecting sensitive fields and records across all application, database, warehouse, BI, AI, and downstream workflows.

Where KMS and Vault Systems Are Not Designed to Go

KMS and Vault systems are not usually designed to be the complete sensitive data protection layer across every place sensitive data is accessed, copied, transformed, exported, embedded, or consumed.

This distinction matters because key access is not the same as sensitive value authorization.

Sensitive values may be accessed, copied, transformed, exported, joined, materialized, logged, embedded, indexed, or consumed by:

Internal users
Developers
Administrators
Application services
Service accounts
APIs
ETL and ELT pipelines
Event streams
Databases
Warehouses
BI tools
Reporting systems
Data science notebooks
AI and RAG workflows
MCP-based tools and agents
Vector stores
Vendor feeds
CSV, JSON, Excel, Parquet, or database exports
Downstream systems
Temporary development or test environments

A KMS or Vault may control whether an application, service, or workload can use a key or retrieve a secret. But once that workload receives cleartext data, the KMS or Vault is often no longer the enforcement point for who should see or use the sensitive value.

That is the architectural gap Ubiq is designed to address.

Key Architectural Differences

Key Management vs Sensitive Value Protection

KMS and Vault systems are designed to manage keys, secrets, certificates, and cryptographic operations.

Ubiq is designed to protect sensitive values and govern whether those values can be revealed in cleartext.

This difference is important.

A KMS may answer:

Is this workload allowed to use this key?

Ubiq answers:

Is this identity, application, service account, pipeline, BI tool, or AI workflow allowed to see this sensitive value in cleartext right now?

Both questions matter, but they are not the same.

Cryptographic Operations vs Runtime Cleartext Authorization

KMS and Vault systems can perform or enable cryptographic operations, such as encrypt, decrypt, sign, verify, generate data keys, wrap keys, unwrap keys, or provide encryption-as-a-service.

These capabilities are foundational.

However, a cryptographic operation does not automatically define the full business policy for sensitive value exposure.

For example, an application may be authorized to use a key, but different users of that application may have different rights to see cleartext. A pipeline may need to process a dataset, but not reveal sensitive values. A BI workflow may need aggregate analysis, but not raw identifiers. An AI workflow may need context, but not direct exposure of sensitive fields.

Ubiq adds runtime policy enforcement at the sensitive value layer.

Key Access vs Identity-Aware Field and Record Controls

KMS and Vault policies often govern access to keys, secrets, paths, tokens, or cryptographic APIs.

Ubiq can apply identity-aware policy at the field and record level.

This makes it possible to apply more precise controls for:

Different users inside the same application
Different applications using the same dataset
Different service accounts with different cleartext needs
Different APIs exposing different sensitive fields
Different BI users with different authorization levels
AI workflows that should not receive raw sensitive values
Downstream systems that should process protected values only

Infrastructure Boundary vs Data Lifecycle Protection

KMS and Vault systems are foundational infrastructure services.

They help secure the cryptographic materials that applications and platforms rely on.

But sensitive data often moves beyond a single application or infrastructure control boundary.

It may be exported to files, copied into downstream systems, replicated into analytics platforms, written into logs, joined into derived datasets, consumed by BI tools, embedded into vector stores, or used by AI workflows.

Ubiq helps maintain protection of selected sensitive values across the data lifecycle. If protected values are copied, exported, embedded, indexed, or consumed downstream, they can remain protected unless an authorized runtime path reveals cleartext.

Secrets Management vs Data Access Enforcement

Vault platforms are often used to store database credentials, API keys, certificates, tokens, and application secrets.

This is essential.

However, controlling access to a database password or API key is not the same as controlling what sensitive values are revealed after access is granted.

An application may authenticate correctly. A service account may retrieve its secret. A database connection may succeed. A query may be allowed.

The remaining question is:

What sensitive values should this identity or workflow actually see?

Ubiq is designed to answer that question at runtime.

When to Use Both

KMS/Vault systems and Ubiq are not mutually exclusive.

Organizations should continue using KMS and Vault systems for:

Key generation and lifecycle management
Secrets management
Certificate management
HSM-backed key protection
Envelope encryption
Key wrapping and unwrapping
Signing and verification
Centralized secret retrieval
Cloud service encryption integrations
Bring-your-own-key and customer-managed-key patterns
Application secret rotation
Key and secret usage auditing

Ubiq should be considered when organizations also need to:

Protect sensitive values directly
Govern cleartext access by identity, role, application, dataset, and context
Apply consistent protection across applications, APIs, databases, warehouses, BI tools, and AI workflows
Limit blast radius from compromised credentials, service accounts, tokens, API keys, or overprivileged users
Restrict cleartext access for non-human identities and automation
Protect sensitive values used by BI, AI, RAG, notebooks, agents, and downstream systems
Maintain protection when data is copied, exported, embedded, indexed, logged, replicated, or consumed downstream
Apply field- and record-level cleartext controls across multiple platforms

The layered model is simple:

Use KMS and Vault systems to protect keys, secrets, and cryptographic operations.
Use Ubiq to protect sensitive values and govern cleartext access at runtime.

How Ubiq Complements KMS and Vault

Ubiq complements KMS and Vault systems by applying data protection and runtime authorization to sensitive values.

KMS and Vault systems help protect the cryptographic materials, secrets, and operations that enterprise systems rely on.

Ubiq helps protect the sensitive data itself.

With Ubiq, selected sensitive fields can remain encrypted, tokenized, masked, or otherwise protected by default. Cleartext access is granted only when the requesting identity or workflow is authorized by policy at runtime.

This allows organizations to:

Use existing KMS, Vault, HSM, BYOK, CMK, or BYOHSM models as part of their trust architecture
Protect sensitive values across applications, databases, warehouses, APIs, and analytics workflows
Control cleartext access for users, applications, service accounts, pipelines, and AI systems
Reduce exposure in BI and reporting workflows
Protect sensitive data used by AI, RAG, notebook, model, and agent workflows
Preserve protection when data is copied, exported, embedded, indexed, logged, replicated, or consumed downstream
Maintain separation between system access, key access, and sensitive value authorization

In this model:

KMS and Vault systems protect keys, secrets, certificates, and cryptographic operations.
Ubiq governs which identities and workflows can access selected sensitive values in cleartext.

Together, they provide a stronger security architecture than either approach provides alone.

Internal Evaluation Questions

When evaluating KMS/Vault systems and Ubiq together, teams should ask:

Which systems manage our keys, secrets, certificates, and cryptographic operations today?
Which applications or workloads are allowed to use those keys or retrieve those secrets?
Which sensitive fields require protection beyond key management?
Which workflows receive sensitive data in cleartext today?
Is key access being treated as equivalent to sensitive value authorization?
What happens when sensitive data is decrypted, exported, copied, logged, joined, materialized, embedded, indexed, or replicated?
Do BI tools, dashboards, extracts, and reports expose sensitive values?
Do AI, RAG, notebook, MCP, vector store, model training, model inference, or agent workflows access sensitive values?
Should service accounts, APIs, pipelines, or automation workflows receive cleartext, or only protected values?
Which control determines whether a specific identity or workflow can see sensitive values in cleartext?
Does sensitive value protection need to work across multiple platforms and data stores?
How do we separate key access from sensitive value access?

Summary

KMS and Vault systems provide critical infrastructure for managing keys, secrets, certificates, HSM-backed trust, and cryptographic operations.

Ubiq addresses a different layer: runtime sensitive data protection.

By protecting selected sensitive values directly and governing cleartext access through identity-aware policy, Ubiq helps organizations reduce exposure across users, applications, service accounts, APIs, pipelines, databases, warehouses, BI tools, AI workflows, exports, logs, and downstream systems.

KMS and Vault systems manage cryptographic trust.

Ubiq controls exposure of sensitive values at runtime.

The strongest architecture uses both.
