Our policies are based on the following foundational principles:
All datastores with customer data, in addition to S3 buckets, are encrypted at rest. Sensitive collections and tables also use row-level encryption.This means the data is encrypted even before it hits the database so that neither physical access, nor logical access to the database, is enough to read the most sensitive information.
Walter uses TLS 1.2 or higher everywhere data is transmitted over potentially insecure networks. We also use features such as HSTS (HTTP Strict Transport Security) to maximize the security of our data in transit. Server TLS keys and certificates are managed by AWS and Cloudflare and deployed via Application Load Balancers.
Encryption keys are managed via AWS Key Management System (KMS). KMS stores key material in Hardware Security Modules (HSMs), which prevents direct access by any individuals, including employees of Amazon and Walter. The keys stored in HSMs are used for encryption and decryption via Amazon’s KMS APIs.
Application secrets are encrypted and stored securely via AWS Secrets Manager and Parameter Store, and access to these values is strictly limited.
Walter engages with independent, Government of Canada approved penetration testing consulting firms in the industry at least annually.
All areas of the Walter product and cloud infrastructure are in-scope for these assessments, and source code is fully available to the testers in order to maximize the effectiveness and coverage.
Static analysis (SAST) testing of code during pull requests and on an ongoing basis
Software composition analysis (SCA) to identify known vulnerabilities in our software supply chain
Malicious dependency scanning to prevent the introduction of malware into our software supply chain
All corporate devices are centrally managed and are equipped with mobile device management software and anti-malware protection. Endpoint security alerts are monitored with 24/7/365 coverage. We use MDM software to enforce secure configuration of endpoints, such as disk encryption, screen lock configuration, and software updates.
Access to customer and corporate data
Integration with production environments
Potential damage to the Walter brand
Once the inherent risk rating has been determined, the security of the vendor is evaluated in order to determine a residual risk rating and an approval decision for the vendor.
Minutebook secures remote access to production resources using state of the art Amazon Web Services Remote Access technology that has undergone extensive testing and independent audit.
Walter provides comprehensive security training to all employees upon onboarding and annually through educational modules within Vanta’s platform. In addition, all new employees attend a mandatory live onboarding session centered around key security principles.
All new engineers also attend a mandatory live onboarding session focused on secure coding principles and practices. Walter's security team shares regular threat briefings with employees to inform them of important security and safety-related updates that require special attention or action.
Walter uses Okta to secure our identity and access management. We enforce the use of phishing-resistant authentication factors, using hardware backed, phishing resistant authenticators exclusively wherever possible.
Walter employees are granted access to applications based on their role, and automatically deprovisioned upon termination of their employment. Further access must be approved according to the policies set for each application.
