Secure Data Analytics with Sigma

Sigma sits atop your existing cloud database and uses a secure connection to query your data warehouse directly. Sigma writes a query to access the data needed to answer your question and returns the result in the browser.

Sigma provides a single point of access for your data, so you can establish robust data governance, keep report sprawl to a minimum, and restrict access to sensitive information. Administrators can set permissions by team and namespace, and restrict data access directly from the database as well.

We built Sigma with security in mind, which is why we included features like immutable hosts, container checking, and threat detection. At Sigma, we make every effort to provide secure data analytics and ensure our platform is protected at every layer of the stack.

Product Security

Ensuring our product meets the robust data security needs of our customers is a top priority at Sigma. We’re continuously releasing and iterating to include the newest security features and stay ahead of the ever-changing and evolving threat landscape. We also work directly with customers with unique security or compliance requirements and add these features as needed.

These are just some of the security features our platform offers customers:

Fine-grained role-based access control – Control which users have access to what information

Single sign-on (SSO) – Use SAML, Okta, OneLogin, GSuite, or your favorite iDP

Row-level security – Limit users to seeing only data that’s relevant to them

Platform and Organizational Security

Sigma invests heavily in having an exceptional security program and ensuring we exceed industry standards. We don’t just buy tools — we make secure data analytics the foundation of everything we do.

Application

Web application firewall

Sigma uses a web application firewall that receives automatic updates to help keep us protected against the latest web application attacks.

Static code analysis

Code is automatically checked for potential vulnerabilities for every commit.

Third-party library vulnerability checking

We check the libraries we use for vulnerabilities and keep them updated at all times.

Credential checking

We check code commits for credentials to ensure they’re not being merged into our code repository.

Peer review

Every commit into the master branch requires a code review before being merged. Each code review is done by a senior engineer.

Infrastructure

Shared responsibility with GCP and AWS

We use cloud providers with extensive data security, compliance, and privacy programs.

High availability

Sigma runs its clusters in multi-zone deployments to ensure high availability in case of a data center or network outage.

Immutable hosts

Our underlying infrastructure is immutable, which means nothing can be installed or changed on these hosts.

Threat detection

Sigma uses the latest cloud security products to check for threats against our infrastructure.

Anomaly detection

We use rules and machine learning to look for anomalies happening in our cloud infrastructure and spot any potential security threats.

Configuration checking

We check our cloud configurations in real time to ensure they are meeting our standards and are always secure.

Network

Encryption in transit (TLS 1.2 Min)

Encryption is enforced between clients and Sigma and all components of the Sigma platform using at least TLS 1.2.

DDoS protection

We utilize multiple layers of DDoS protection from leading providers in the industry.

DNSSEC

Sigma uses DNSSEC to prevent DNS spoofing / hijacking, and we sign all of our zones including development and production.

Spoofing protection

Network spoofing is blocked internally and across all instances.

No connectivity between production and office networks

We do not connect our cloud networks to our office networks. We keep them separate to ensure our office network never affects our production network.

Endpoints

Mobile device management

All Sigma assets are managed assets and enforce our security policies.

Endpoint detection response

We use the latest endpoint security tools in EDR, which go beyond simple anti-virus alerting and allow us to see the details around any potential compromises.

Advanced persistent threat detection

We scan packages for the latest APT indicators and sandbox those packages to ensure they’re not a threat.

DNS filtering

We filter DNS for malicious (malware/phishing/etc.) requests that could harm our employees or infrastructure.

General

Third-party penetration test

Sigma pays for a yearly third-party penetration test, complete with a social engineering/phishing element, done by experts in the industry.

Annual security training

We make all employees complete extensive annual security training that covers over 13 different subject areas.

Quarterly phishing tests

We phish our employees regularly to help keep security top of mind and teach them how to easily spot phishing emails.

Cloud Security Alliance (CSA)

Sigma has completed the CSA’s Consensus Assessments Initiative Questionnaire (CAIQ), which provides a set of questions a cloud consumer may wish to ask to ascertain a solution’s compliance to the Cloud Controls Matrix and CSA best practices.

General Data Protection Regulation (GDPR)

At Sigma, we firmly support GDPR in both practice and philosophy. We work with our customers in the European Economic Area to assure compliance with personal data handling requirements and cross-border transfer requirements under GDPR.

As a processor, we process data on behalf of our customers. We expect that some of our customers will require us to enter into a data processing addendum (“DPA”), per Article 28 of GDPR.

Sigma uses several subprocessors, but the majority of our obligations hinge on our primary subprocessor: Google Cloud Platform. Read more about Google Cloud Platform’s commitment to GDPR here. And for a full list of our subprocessors, click here.

California Consumer Privacy Act (CCPA)

Sigma will support any removal request from any state/country as long as it is valid and made by a qualified party.
