Security and compliance programs
Background checks

All Calendly employees go through a thorough background check before hire.


While we retain a minimal amount of customer data and limit internal access on a need-to-know basis, all employees are trained on security and data handling to ensure that they uphold our strict commitment to the privacy and security of your data.


All employees sign a confidentiality agreement before they start at Calendly.

Reliability and redundancy
Business continuity and disaster recovery

We have business continuity and disaster recovery plans in place that replicate our database and back up the data onto multiple cloud providers to ensure high availability.

Software development lifecycle
Routine audits

Calendly continuously scans the product for service interruptions, performance degradation and security vulnerabilities to immediately alert our engineers and take action when an incident has been detected.

New releases

New releases to the Calendly platform are thoroughly reviewed and tested to ensure high availability and a great customer experience. Changes to our codebase are required to include unit tests, integration tests and end-to-end tests. Changes are run against our continuous integration server, which enables us to automatically detect any issues in development.

Quality assurance testing

Once a changeset is completed, it is manually peer reviewed by one or more members of the engineering team. The changeset is then evaluated and manually tested by our quality assurance team to thoroughly test areas of expected impact, regression test and further evaluate the user experience.

Continual monitoring

After a changeset is released, we continue to monitor application exceptions and log exceptions. These exceptions are regularly reviewed and triaged for resolution. Performance impacts of the changeset are monitored through several monitoring services.

Vulnerability control
Mobile device management (MDM)

We secure our employees' machines and laptops using mobile device management to ensure that each device follows our information security standards, including encryption.

Malicious software prevention

Our employees’ equipment is defended by anti-malware software, and we run routine phishing tests to further educate and train employees.

Vulnerability scanning

We keep our systems up to date with the latest security patches and continuously monitor for new vulnerabilities through compliance and security mailing lists. This includes automatic scanning of our code repositories for vulnerable dependencies.

Application security measures
Login credential protection

For Google Calendar and Office365 calendar connections, Calendly never collects passwords. Using a secure OAuth connection to sync these calendars only grants Calendly access to your calendar account through a secure token from your email provider. This also enables you to set additional security precautions with that provider including 2-factor authentication (2FA). For iCloud users, we recommend setting up 2FA and application-specific passwords. For organizations with enhanced security requirements, Calendly supports SAML-based Single sign-on (SSO) with the following identity providers: Okta, Ping Identity, Azure, OneLogin, and Auth0.

User provisioning and deprovisioning

Calendly offers seamless OAuth through Google Calendar and Office365, calendar connection is eliminated automatically when your account is canceled. For larger organizations, Calendly supports automatic provisioning and deprovisioning via SCIM if using one of our supported identity providers: Okta, Ping Identity, Azure, OneLogin, and Auth0.
