Security at Kinde

Kinde takes security threats very seriously as the integrity, confidentiality, and availability of our systems potentially impact our customers. If you have detected a security threat or vulnerability against Kinde systems or personnel, please reach out to your account manager or to the security mailing group at

Kinde production services are designed to be resistant to failure with multiple front-end servers and replicated back-end databases. Our main production databases are provisioned, but we use serverless for some supporting roles.

All services are setup in AWS and are configured to use multiple availability zones for redundancy. Please refer to the Kinde status page for uptime metrics.

Native bot detection is on the roadmap, which will allow customers to bring their own CloudFlare integration key to apply bot detection and protections directly to their Kinde hosted auth pages. This will allow customers to adjust the level of protection based on their own risk profile. Please see our roadmap for updates.

Alternatively, customers can implement bot detection and CAPTCHA if your DNS is hosted via CloudFlare. Kinde’s hosted pages, with a custom domain, can be proxied through CloudFlare to incorporate advanced web attack protection features, including bot detection and CloudFlare’s Turnstile (CloudFlare’s equivalent to CAPTCHA).

Brute force protection

Link to this section

Kinde protects from brute force attacks with a combination of techniques. To protect against volumetric attacks, we use AWS WAF to block traffic that matches OWASP threat rules and also use our own application throttling. To protect against password brute forcing, we will automatically lock out accounts after 5 consecutive failed attempts of the passwordless code (OTP, password, or multi-factor authentication code for a short period of time. Admins can manually unlock accounts if necessary.

Suspicious IPs performing large scale scanning and probing will automatically blocked for a short amount of time based on configured rate limits. Kinde has rate limit thresholds for “buckets” of traffic such as API or token events, which can be tuned with help from our support team.

Business continuity and disaster recovery

Link to this section

Kinde has documented and tested both our business continuity plan and disaster recovery plan. These are updated and refreshed at least annually to ensure that technical events such as a database failover or business impacting events such as a communications tool outage are understood with redundancy plans in place.

Kinde holds a certificate of registration for ISO 27001:2022 and has a SOC 2 attestation. Please refer to our Compliance certifications page for more information.

Data residency

Link to this section

Data is stored in the region you selected during sign up of our product. Currently the available regions are Sydney, Australia; Dublin, Ireland; Oregon, USA; and London, UK. The only data replicated between regions is backend metadata to facilitate the operation of the production services. Otherwise, all user data is not replicated between the regions and will remain in it’s original region.

Denial of service

Link to this section

Kinde uses a layered approach to protect it’s customers from denial of service attacks to the authentication pages and API, such as protections provided by AWS Shield, rate limiting rules with AWS WAF, and application based throttling.

Encryption for data at rest

Link to this section

All customer data at rest is encrypted in the Kinde production databases using the industry standard AES256 encryption algorithm. Encryption is facilitated by AWS KMS with access to administer KMS strictly limited to privileged admins.

Encryption for data in transit

Link to this section

All network traffic to Kinde production services uses TLS 1.2 or greater with a limited set of modern secure ciphers enforced. Security headers are applied to all production endpoints where possible.

Identity management

Link to this section

Internal identity is generally managed through the company’s single sign-on (SSO) platform provided by Google Workspace. All systems are connected to the company SSO platform where supported. Multi-factor authentication is enforced for all users and audit logs are enabled and monitored for systems connected to the company SSO. For systems that do not support SSO, employees are required to use the company provided password manager to generate and manage secure credentials as well as enable MFA for added protection.

Access to systems is based on the employee’s job role with the least privileges assigned. Privileged access to any system is strictly limited based on the employee’s job role and accounts are individual to that user only.

Penetration testing

Link to this section

Kinde has completed a network and web application penetration test conducted by Strike, which was scoped for anything and everything related to Kinde. The test included common OWASP techniques and specifically targeted workflows such as privilege escalations, authentication bypasses, and cloud security. We intend to perform these at least annually.

Security awareness

Link to this section

All employees take part in a security onboarding session during their first week that covers topics such as acceptable use, phishing, data privacy, identity, endpoint protection, data classification, and incident response.

Software development lifecycle

Link to this section

All Kinde source code is managed by a company managed source code repository. Source code is scanned using a suite of open source tools, which will alert on insecure coding that could lead to vulnerabilities. Access to the source code repository is restricted based on job role with the identity linked to the company single sign-on platform. Merges to source code require a peer review. Pull requests to the master branch are performed by senior engineers.

Vulnerability management

Link to this section

Production services are deployed through a CICD pipeline using container technology. Server builds are done at least once a week and replace the existing servers. The build process will use the latest patched container host and container image to reduce the risk of vulnerabilities due to unpatched software.

All container images are scanned at build using AWS Inspector for dependencies and third party library vulnerabilities. External production URLs and any public facing cloud IP addresses are scanned weekly for vulnerabilities by Intruder. All vulnerability reports are triaged, analysed, and assigned to the engineering team for remediation based on vulnerability management SLAs.
