Effective Date: May 14, 2018

Capitalized terms that are not defined in these Security Measures have the meanings set forth in the Terms of Service or the Data Processing Addendum.


Security Overview

Squarespace has a dedicated security team that guides the implementation of controls, processes, and procedures governing the security of Squarespace and its customers. The Squarespace security team is responsible for developing, implementing and maintaining an information security program that reflects the following principles:

  • Align security activities with Squarespace’s strategies and support Squarespace’s objectives.
  • Leverage security to facilitate confidentiality, integrity, and availability of data and assets.
  • Utilize Squarespace’s security resources efficiently and effectively.
  • Utilize monitoring and metrics to facilitate adequate performance of security related activities.
  • Manage security utilizing a risk based approach.
  • Implement measures designed to manage risks and potential impacts to an acceptable level.
  • Leverage industry security frameworks where relevant and applicable.
  • Leverage compliance/assurance processes as necessary.
  • Analyze identified or potential threats to Squarespace and its customers, provide reasonable remediation recommendations, and communicate results as appropriate.  

Data Center Security, Availability, and Disaster Recovery

  • Squarespace leverages leading data center providers to house our physical infrastructure.  
  • Our data center providers utilize an array of security equipment, techniques and procedures designed to control, monitor, and record access to the facilities.
  • We have implemented solutions designed to protect against and mitigate effects of DDoS attacks.    
  • We have dedicated teams located in multiple geographies to support our platform and supporting infrastructure.  
  • Squarespace maintains geographically separate data centers to facilitate infrastructure and service availability and continuity. 
  • Squarespace has a formally documented disaster recovery (failover) plan which is tested at least annually. Results of testing are documented and maintained.  

Application Level Security

  • Squarespace hashes passwords for user accounts and provides SSL for customers.  
  • Squarespace utilizes Web Application Firewall (WAF) technology.
  • Regular pen testing is performed on the Squarespace platform, the results of which are analyzed and remediated (as appropriate) by our engineering and security teams.  
  • Customers are provided the ability to customize website permissioning.

Incident Response

  • In the event of an issue related to the security of the Squarespace platform, the Squarespace security team follows a formal incident response process.  
  • We analyze identified or potential threats to Squarespace and its customers, provide reasonable remediation recommendations, and communicate results as appropriate.

Squarespace Building and Network Access

  • Physical access to Squarespace offices and access to the Squarespace internal network is restricted and monitored.  

Systems Access Control

  • Access to Squarespace systems is limited to appropriate personnel.
  • Squarespace subscribes to the principle of least privilege (e.g., employees, system accounts, vendors, etc. are provided with the least amount of access for their job function).
  • Squarespace leverages multifactor authentication.

Security Risk Management

Threat intelligence and risk assessment are key components of Squarespace’s information security program. Awareness and understanding of potential (and actual) threats guides the selection and implementation of appropriate security controls to mitigate risk. Potential security threats are identified, and assessed for severity and exploitability prior to being classified as risks. If risk mitigation is required, the security team works with relevant stakeholders and system owners to remediate. The remediation efforts are tested to confirm the new measures/controls have achieved their intended purpose.
