Overview

Product Information on ALTR Data Access Control and Security

Updated 10th May 2023

What is ALTR Data Access Control and Security?

ALTR provides data access control to automate data governance and security at scale. Data classification, role-based access controls, dynamic data masking, real-time rate limiting, and alerting are available through a point and click user interface or via APIs. The interface enables non-technical users to control and protect data without knowing how to code. It can accelerate the time it takes to make new data and workloads available to users.  The platform is SaaS, requiring no on-premises hardware or installation. Automated policy enforcement minimizes the time spent on manual user access management, and open-source integrations with many leading Data Catalogs and ETL/ELT providers allow policies to follow sensitive data through data pipelines into data catalogs and new data stores. ALTR connects with data warehouses including Snowflake, Microsoft SQL Server, MySQL and Redshift. Real-time security alerts can be delivered directly to enterprise SIEM, SOC or SOAR security solutions.

Reviewer Insights for: ALTR Data Access Control and Security

ALTR Data Access Control and Security Likes & Dislikes

Like

Ease of deployment that returns immediate value and visibility.

Like

Simple User Interface No-code solution to Data Masking Non-engineers can implement Data Masking Native compatibility with Snowflake Cloud-based installation (no infrastructure!)

Like

We appreciate ALTR's completeness of vision for their product, their ability to execute, their support, as well as their integration with other tools such as ATLAN.

Dislike

Given the easy of deployment of the ALTR platform, it would be awesome to see more databases and warehouses supported at scale.

Dislike

Initial installation had off-platform solutions (custom scripts were provided by ALTR to help speed up our application of tags en masse) Initial installation had challenges, due to the off-platform solution (those same custom scripts accidentally complicated deployment, as the ALTR product did not have any record of what the scripts performed) We hit scalability issues masking a massive dataset (we had spinning queries on a single masking policy applied to billions of records on 80cols simultaneously). The issue is related to inconsistent communication between ALTR's external functions being executed in Snowflake; Snowflake didn't know when the external functions complete, which causes queries to spin endlessly. We also found a Snowflake bug in the process, which prevented the queries from being cancelled. Both bugs have since been resolved by the appropriate vendors.

Dislike

Occasionally we have an issue with their connection to our database where we have to rerun their stored procedure for permissions. I believe this is due to us having been an early adopter and switching from partner connect to their more direct model.

    Fantastic, simple solution to Snowflake Data Masking

    4.0
    Jun 17, 2025
    ALTR provides a simple interface to implement complex Snowflake functionality. ALTR's customer support and on-boarding process has been exceptionally helpful during this time - really above and beyond. We did have some hiccups with initial setup; specifically with the complexities of applying tags en masse in our Snowflake environment. The ALTR team helped us by providing scripts to mass create/update tags, but this was a workaround outside of the actual product which ultimately led to more troubleshooting. Ideally this would not have happened, but the ALTR team was extremely attentive and helpful getting us through the challenges. They are also upgrading the product to streamline the setup process so future customers have an easier time.
