Security & Reliability FAQs
Where is data in STACK stored?
STACK is a cloud-native SaaS platform hosted on Microsoft Azure. All customer data is stored within Azure's United States or Canadian data center regions, Takeoff & Estimate or Build & Operate, respectively. Data is continuously geo-replicated between regions within each country to ensure high availability and durability. Document storage provides 99.999999999% durability with soft delete enabled, and application data is maintained in-country geo-redundant storage with automatic replication. In the event of a regional outage, automated failover redirects traffic to the secondary region in under five minutes.
How is data encrypted?
STACK encrypts all sensitive data in transit using TLS 1.2 at minimum with common secure ciphers. STACK also encrypts data at rest using AES-256 equivalent or stronger encryption algorithms, depending on the application, i.e., databases, cloud storage, mobile devices, desktops, and laptops.
How often are backups performed?
STACK leverages Azure's built-in backup and redundancy capabilities to protect customer data. Application data and document storage are continuously geo-replicated between our primary and secondary regions, ensuring near-real-time data protection. Automated backups are performed on a recurring schedule with point-in-time restore capabilities. Backup and recovery procedures are validated as part of STACK's annual SOC 2 Type 2 audit.
What is STACK's uptime SLA?
STACK guarantees 99.9% uptime for its SaaS offerings (subject in all cases to specific terms regarding uptime as set forth in the STACK Terms of Use). Current and historical uptime can be seen at https://status.stackct.com/.
Does STACK support SSO?
Yes. STACK leverages, a leading authentication and authorization platform, to provide single sign-on (SSO), two-factor authentication, and identity analytics. STACK's SSO is compatible with a wide range of applications, allowing organizations to integrate new tools and platforms as they evolve. STACK supports both traditional SSO (Takeoff & Estimate) within a single organization and federated SSO (Build & Operate) for cross-organizational collaboration.
How does STACK handle maintenance?
STACK's use of container technology allows us to perform deployments that include maintenance changes, bug fixes, security updates, and new features transparently with little to no customer impact multiple times per day, or as needed.
