Baffle

Transparent proxy that encrypts, tokenises and masks database fields without application code changes

As of 31 August 2026, Baffle's pricing is not published; the vendor quotes on request. Baffle sits in front of databases and data pipelines as a proxy and applies field-level encryption, tokenisation and masking without touching application code. Softwr lists it under Cybersecurity. Baffle is made by Baffle, Inc., available on Linux, Web.

Overview

What Baffle does

Baffle protects structured data at field level. It deploys as a transparent proxy between applications and data stores, intercepting traffic and applying encryption, tokenisation, format-preserving de-identification or dynamic masking on the way in and out, with role-based control over who sees real values. It supports customer-held keys, and works across PostgreSQL, MySQL and equivalent managed cloud databases, plus analytics targets including Snowflake, Amazon Redshift, S3 and Kafka streams, and increasingly data flowing into AI pipelines. The distinguishing property is that applications do not change. Most field-level encryption approaches require developers to call an SDK at every read and write, which means finding every code path and re-testing everything. Baffle intercepts at the wire instead, so a legacy application that nobody wants to modify can be brought into scope for encryption in weeks. For organisations facing an audit finding on data at rest in a system they cannot safely refactor, this is often the only realistic option. Buyers are financial services, healthcare and any enterprise carrying regulated fields in databases that predate their current security standard. The trade-off is architectural: you are inserting a component into the production data path, so latency, failover, connection pooling behaviour and support for your exact driver and SQL feature set all have to be proved in your environment rather than assumed. Queries against encrypted columns are also constrained; what operations remain possible depends on the protection mode chosen, and choosing a stronger mode can break reporting that used to work.

What people use it for

A bank with a legacy application it cannot safely refactor that has an audit finding requiring field-level encryption of account data
A company wanting to take a reporting database out of PCI scope by tokenising card fields before they land
A healthcare organisation that must ensure database administrators and cloud operators cannot read patient identifiers in the tables they administer
A team moving regulated data into a warehouse or an AI retrieval pipeline that needs identifiers de-identified in transit without rewriting the ingest jobs

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Baffle.

The proxy sits in the production data path, so it becomes a latency contributor and a failure domain, and any deployment needs load and failover testing that customers routinely underestimate.
What you can still do in SQL depends on the protection mode chosen, and stronger modes restrict comparisons, joins and aggregations on protected columns, which can quietly break existing reports and analytics.
Database and driver coverage is finite, so an organisation with an unusual engine, an old driver or heavy use of stored procedures may find its most important system is exactly the one not supported.
Pricing is unpublished and scales with protected data stores, which means an enterprise trying to protect a long tail of small databases pays disproportionately compared with protecting a handful of large ones.
Key management is your responsibility under bring your own key, and while that is the correct security posture, it moves a real operational burden and a genuine data-loss risk onto the customer.

What people choose instead of Baffle

Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Capabilities

Features

Transparent proxy deployment
Sits between application and database so no application code changes are required

Tokenisation
Replaces sensitive values with tokens, useful for taking systems out of compliance scope
Format-preserving de-identification
Keeps value shape so downstream systems and validations continue to work
Dynamic data masking
Shows different values to different roles at query time
Bring your own key
Keys held in the customer key management service rather than by the vendor
Analytics and pipeline support
Protection extended to Snowflake, Redshift, S3 and Kafka as well as transactional databases
AI pipeline protection
De-identification of data flowing into model and retrieval workflows

Questions people ask

Each answer names the page it came from, so you can check it rather than take our word for it.

Do applications need code changes?

No. That is the central design choice. Baffle intercepts traffic as a proxy rather than requiring an SDK call at every read and write.

Can you still query encrypted columns?

Partly, and it depends on the protection mode. Some modes preserve equality matching and format, stronger modes restrict what SQL operations remain possible, so this must be tested against your actual queries.

Does it take systems out of PCI scope?

Tokenisation can reduce scope by ensuring card data never lands in the protected system, but scope reduction is an assessor judgement, not a product setting.

Who holds the encryption keys?

You do, through your own key management service. Baffle supports bring your own key rather than holding customer keys itself.
