Cloud Security

• Data Center Physical Security Facilitiessome text
  • Scarf relies on infrastructure from Amazon AWS for data center hosting. Our provider data centers are certified as ISO 27001, PCI DSS Service Provider Level 1, and or SOC 2 certified.

Our providers employ robust controls to secure the availability and security of their systems. This includes measures such as backup power, fire detection and suppression equipment, secure device destruction amongst others.

Network Security

• In-house Security Team
• Scarf has a dedicated and passionate technical team across the globe to respond to security alerts and events.

Third-Party Penetration Tests

‍Third party penetration tests are conducted against the application and supporting infrastructure at least annually. Any findings as a result of tests are tracked to remediation. Reports are available on request with an appropriate NDA in place.

Threat Detection

‍Scarf deploys threat detection services within AWS to continuously monitor for malicious and unauthorized activity.

‍Vulnerability Scanning

‍We perform regular internal scans for vulnerability scanning of infrastructure. Where issues are identified these are tracked until remediation.

Access Control

‍Access is limited to a least privilege model required for our staff to carry out their jobs. This is subject to regular internal audit and technical enforcement and monitoring to ensure compliance. MFA is required for all production systems.

Encryption

In Transit

• Communication with Scarf is encrypted with TLS 1.2 or higher over public networks. We monitor community testing & research in this area and continue to adopt best practices in terms of Cipher adoption and TLS configuration.

At Rest

‍‍Scarf data is encrypted at rest with industry standard AES-256 encryption. By default we encrypt at the asset or object level.

Availability & Continuity

Uptime

• Scarf is deployed on public cloud infrastructure. Services are deployed to multiple regions and availability zones for availability and are configured to scale dynamically in response to measured and expected load.

Scarf maintains a publicly available status page which includes details on system availability, scheduled maintenance windows and service incident history details.

Disaster Recovery

‍The Scarf gateway is deployed in multiple global regions. In the event of a major region outage, Scarf has the ability to deploy our application to a new hosting region. Our Disaster Recovery plan ensures availability of services and ease of recovery in the event of such a disaster. This plan is regularly tested and reviewed for areas of improvement or automation.

DR deployment is managed by the same configuration management and release processes as our production environment ensuring that all security configurations and controls are applied appropriately.

Application Security

‍Environment Segregation

• Testing, staging and production environments are logically separated from one another. No customer data is used in any development or test environment.

Personal Security

‍Security Awareness

• Scarf delivers employees a robust Security Awareness Training program which is delivered within 30 days of new hires and annually for all employees.

Information Security Program

‍Scarf has a comprehensive set of information security policies covering a range of topics. These are disseminated to all employees and contractors and acknowledgement tracked on key policies such as Acceptable Use, Information Security Policy and our Employee Handbook.

Employee Background Checks

‍All Scarf employees undergo a background check prior to employment which covers 5 years criminal history where legal and 5 years employment verification.

Confidentiality Agreements

‍All employees and contractors are required to sign Non-Disclosure and Confidentiality agreements.

Access Controls

‍Access to systems and network devices is based upon a documented, approved request process. Logical access to platform servers and management systems requires two-factor authentication. A periodic verification is performed to determine that the owner of a user ID is still employed and assigned to the appropriate role. Access is further restricted by system permissions using a least privilege methodology and all permissions require documented business need. Exceptions identified during the verification process are remediated. Business need revalidation is performed on a quarterly basis to determine that access is commensurate with the users job function. Exceptions identified during the revalidation process are remediated. User access is revoked upon termination of employment or change of job role.

Data Privacy

‍GDPR

• Scarf maintains compliance with the European Union’s General Data Protection Regulation (GDPR).

PCI-DSS

• As a card not present merchant, Scarf outsources our cardholder functions to a PCI-DSS Level 1 service provider. A copy of our SAQ-A can be available on request.

Privacy Policy

‍Scarf’s privacy policy, which describes how we handle data collected by Scarf, can be found at https://about.scarf.sh/privacy-policy . For privacy questions or concerns, please contact help@scarf.sh.

Third Party Security

‍Vendor Management

• Scarf understands the risks associated with improper vendor management. We evaluate and perform due diligence on all of our vendors prior to engagement to ensure their security is to a suitable standard. Selected vendors are then monitored and reassessed on an ongoing basis, taking into account relevant changes.

Third-Party Sub Processors

‍Scarf uses third-party sub processors to provide core infrastructure and services which support our applications. Prior to engaging any third party, Scarf evaluates a vendor’s security as per our Vendor Management Policy.
