Architected for data security from the start

Looker’s data platform sits on top of your existing database, using a secure connection to query your data warehouse directly. Looker writes a query to access the data needed to answer your question, returns the result, and holds the answer in a short-lived cache (which is cleared after 30 days, or when the amount of data in cache hits 2GB). If you prefer, you can also take additional steps to reduce the amount of time that query results are held in cache.

Because Looker provides a single point of access for your data, you can establish a robust data governance infrastructure, giving everyone within your company the ability to answer their own questions while keeping data sprawl to a minimum and access to sensitive information restricted. Administrators can set granular permissions by user or group, and can restrict data access from the database level all the way down to the row or column level.

Administrators can build robust business intelligence data governance that results in a secure experience for their users.

Your data stays in your control

Looker is built to ensure that the data in your database is safe and secure by limiting its movement.

Leverage Your Database’s Security Protocols

Unlike other business intelligence platforms that encourage you to pull your data out to analyze it, Looker generates SQL that directly queries your database.

Data Availability, Not Data Storage

Looker can be configured to use a read-only connection to access the minimum amount of data needed to answer your questions and to return only the relevant result set. That means less data duplication and no long-term storage of sensitive data on local machines, while leveraging the full power of your existing database security model.

Data governance from the bottom up

Self-service shouldn’t come at the expense of data governance.

Secure User Access and Management

Looker makes it easy for administrators to control users’ access from the database level down to the field level.

Configuration Made Easy

Application permissions, data access, and content access can be configured in the application, managed programmatically via Looker’s API, or inherited directly from your existing single sign-on authentication protocols.

Enterprise-grade feature set

Authenticate Your Way

Looker’s business intelligence platform comes standard with enterprise-grade features including two-factor authentication, SAML-based single sign-on (supporting SAML, OneLogin, and Google Apps), and team management to keep Looker access secure and up-to-date.

Industry-Standard Data Security Encryption

Looker uses industry-standard AES encryption to secure your database connection credentials and cached data stored at rest. We use TLS to encrypt network traffic between users’ browsers and the Looker platform.

Tools to Secure Your Database Connection

Looker offers many options for securing connections to your database, including IP whitelisting, SSL, SSH, PKI, and Kerberos authentication.

SOC 2 Type 2 Compliant

Comprehensively monitored and fully auditable

Because Looker’s data platform provides a single point of contact for employees’ work with your enterprise’s data, it’s far easier to keep track of exactly who accessed what, when, and what they did with it.

Easily Monitor Usage and Track Development

Looker logs every interaction so administrators can audit usage and easily set up scheduled reports and alerts. And because Looker’s data model is version-controlled, you can also track when metric definitions have changed, who changed them, and why.

Easy Configuration of Support Access

Looker monitors and regularly audits technical support employees’ access to your instance. Additionally, you control that access and can easily turn it on or off.

Three Ways Looker Supports GDPR Compliance


A simpler, transparent architecture for data processing which reduces data sprawl and can comply with GDPR requirements - while providing modern data delivery capabilities and crucial insights to drive business success.


The Looker data platform provides numerous product features to assist with data management, setup, and processes to help you meet data security and privacy GDPR requirements.


Looker’s data security program is designed to ensure that company policies, controls and processes are appropriate to the type of personal data and data processing collected.

Our shared security partnership

Looker connects to your organization’s database, and is designed to leave your data in that database. Because Looker connects to technology that you are responsible for maintaining, security becomes a shared responsibility between Looker and you. If you use embedded analytics functionality (Powered by Looker), Looker has developed security best practices you can leverage to help mitigate security concerns.

Application Data Shared by Looker

While there is no permanent storage of your data in the Looker application, Looker utilizes a number of first- and third-party tools in order to provide and improve the service. Unless stated, all services share data with locations in the United States. Application services are outlined below.

Licensing data

A Looker service that gathers information about how the service is being used to ensure that usage is in compliance with the customer’s licensing terms. This information includes metadata about users, roles, database connections, server settings, features used, API usage, and version.

Product usage

A Looker service and a third-party service (Google Analytics 360) that gather pseudonymized usage data about how users are using the Looker product and how well it is performing. This data is analyzed and used to improve the Looker product. Administrators can disable these services for their instance by contacting Support.

Configuration backups

A Looker service that encrypts backups of Looker system’s configuration, which includes saved Looks, query history, encrypted user and database credentials, and Looker user settings. For redundancy, configuration backups are stored in multiple cloud providers including AWS, Google Cloud, and/or Microsoft Azure.

System error reports

A Looker service that transmits runtime exceptions to Looker internal systems in order for Looker technicians to diagnose issues with the product. These messages are first sent as HTTPS requests, but will fail-over to email via a customer’s Looker’s SMTP settings if necessary.

Support access

An optional Looker service that allows Looker technicians to troubleshoot problems by permitting authentication into a customer’s Looker application. This access is limited to Support use cases and can be disabled when not needed by customers.

Data Actions

An optional Looker service that forwards data to a variety of third-party services. Any data your users send using an action will be processed temporarily on Looker’s managed Action Hub rather than in your Looker instance. https://docs.looker.com/admin-options/platform/actions

Email notifications

An optional third-party service (SendGrid) that transmits emails from noreply@looker.com and noreply@lookermail.com in order to provide new account welcome emails, forgotten password reset links, and scheduled data delivery for Looker users. If you prefer, you can alter this configuration to use your own SMTP integration instead.

LookML storage

An optional third-party service (GitHub) that allows for the development and storage of a customer’s LookML code. If you prefer, you can alter this configuration to use your own Git integration instead.

In-app guides and in-product messaging

An optional third-party service (Pendo) that delivers personalized messages to users to help them more easily use the Looker product. This service collects basic pseudonymized usage data in order to personalize messages and guides. Administrators can disable this service for their instance.

Support chat and tickets

An optional third-party service (Zendesk) that provides an embedded chat client in order to facilitate product support.

NOTE: We regularly review both our internal services and third-party service providers to ensure that the data we collect is aligned with the service’s intent, and that the security measures employed meet our high security standards.

Looker’s Responsibilities

Cloud security Looker uses established public cloud hosting providers to augment Looker’s security program with additional security and availability operational controls.
Product security Looker is responsible for ensuring that the code quality for the Looker application is developed according to industry-wide best practices for software development, and is regularly tested for vulnerabilities.
Corporate security Looker is responsible for educating and disseminating security best practices throughout its organization, and ensuring that Looker’s ancillary applications, systems, and networks are securely configured and monitored.
Physical security Looker is responsible for monitoring the Looker corporate facilities, and ensuring that offices and hardware are both protected.

Your Responsibilities

Cloud security

You are responsible for configuring secure access between the Looker application and your database. Looker provides extensive recommendations on how to do this, including:

  • Enabling secure database access using tools like IP whitelisting, SSL/TLS encryption, and SSH tunneling

  • Setting up the most locked-down database account permissions for Looker that still allow it to perform needed functions

Product security

You are also responsible for controlling access and permissions for users of your Looker instance within your company. Looker recommends:

  • Setting up user authentication using either a native username/password option or, preferably, using a more robust authentication mechanism like 2FA, LDAP, Google OAuth, or SAML

  • Setting up the most restrictive user permissions and content access that still allow people to carry out their work, paying special attention to who has admin privileges

  • Setting up any API usage in a secure way

  • Regularly auditing any public access links your users create and restricting the permission to create them, as necessary

Cloud Security Architecture

Looker hosts the Looker application on proven public clouds, which means that as a Looker customer you’ll inherit the robust standards of cloud security maintained by our cloud partners (currently AWS and Google Cloud), which Looker builds on top of for its own security best practices. Looker also uses industry best practices for the development and testing of the Looker application, ensuring that code quality meets our standards before becoming part of a Looker release.

Cloud Infrastructure
Public cloud facilities The Looker application is managed in public cloud datacenters. These facilities implement various physical and environmental controls to ensure that Looker customer data is well protected from possible theft or loss.
Logical separation of data While Looker does not persist customer database information, the application does store configuration information, event data, and cached query results. Looker is architected to logically separate this information in order to isolate customer data and reduce cross-tenant exposure risk.
Data Security Architecture Looker follows best practices for security architecture. Proxy servers secure access to the Looker application by providing a single point to filter attacks through IP blacklisting and connection rate limiting.
Redundancy Looker employs a Cloud-based distributed backup framework for Looker-hosted customer servers.
Availability and durability The Looker application can be hosted in a variety of different public cloud data centers across the globe.
