Understand our Security Policy

Security Policy

This Security Policy describes Emailchaser's security program and technical and organizational security controls to protect customer data from unauthorized use, access, disclosure, or theft and safeguard the Emailchaser services. As security threats change, Emailchaser continues to update its security program and strategy to help protect customer data and Emailchaser services. As such, Emailchaser reserves the right to update this Security Overview from time to time; provided, any update will not materially reduce the overall protections stated in this Security Overview.

Security Program

Emailchaser maintains a risk-based security assessment program. The framework for Emailchaser's security program includes administrative, organizational, and technical safeguards designed to protect Emailchaser's services and confidentiality, integrity, and availability of customer data. Emailchaser's security program is intended to be appropriate to the nature of the Emailchaser services and the size and complexity of Emailchaser's business operations.


All Emailchaser employees and contract personnel are bound by contractual agreements and Emailchaser's internal policies regarding maintaining the confidentiality of customer data and are contractually obligated to comply with these obligations.

People Security

All Emailchaser employees must complete a security and privacy training which covers Emailchaser's security policies, security best practices, and privacy principles. All application passwords must be saved on a password manager. Each service must have its unique password. When available, two-factor authentication (2FA) must be enabled. When available, by using a physical key. Otherwise, by using a 2FA application. SMS 2FA is not allowed.

Third Party Vendor Management

Vendor Assessment

Emailchaser may use third party vendors to provide certain services. Emailchaser carries out a security risk-based assessment of prospective vendors before working with them to validate they meet Emailchaser's security requirements.

Vendor Agreements

Emailchaser enters into written agreements with all of its vendors which include confidentiality, privacy, and security obligations that provide an appropriate level of protection for customer data that these vendors may process.

Hosting Architecture and Data Segregation

Google Cloud Platform

The Emailchaser services are hosted on Google Cloud Platform (GCP) in the United States. customer data stored within GCP is encrypted at all times. GCP does not have access to unencrypted customer data. More information about GCP security is available at


Databases are not open to the world: any connection from a disallowed IP address will be rejected. Only connections from inside Emailchaser's internal network (on Google Cloud or on the Cloudflare network) are allowed. When possible, data is pseudonymized. In particular, data related to email verifications. Pseudonymization prevents the data to be exploited in case of a breach. OAuth and refresh tokens are stored encrypted, using the aes-256-cbc algorithm. Passwords are stored encrypted, using the 'bcrypt' function.


For the Emailchaser services, all network access between production hosts is restricted, using access control lists to allow only authorized roles to interact in the production network. Access control lists are in use to manage network segregation between different security zones in the production and corporate environments. Access control lists are reviewed regularly.

Security by Design

Emailchaser follows security by design principles when it designs the services. This includes, the performance of internal security reviews before deploying new services or code; penetration tests of new services by independent third parties; and regular scans to detect potential security threats and vulnerabilities.

Access Controls

Provisioning Access

To minimize the risk of data exposure, Emailchaser follows the principles of least privilege through a role-based-access-control model when provisioning system access. An employee's access to customer data is promptly removed upon termination of their employment. In order to access the production environment, an authorized user must have a unique username and password and multi-factor authentication enabled. Emailchaser logs high risk actions and changes in the production environment. By default, links holding data (password reset, email change, email validation, etc.) are encrypted using the 'aes-256-cbc' algorithm. We leverage automation to detect any deviation from our internal technical standards such as malicious usage.

Password Controls

Users cannot create an account on Emailchaser using a compromised password from the database.


The following logs of actions are stored:

        on Google Cloud Logging, every HTTP request is logged;

        every user sensitive action is stored in the database;

        every support agent action is stored in the database.

Vulnerability Management

Emailchaser maintains controls to mitigate the risk of security vulnerabilities by using a third-party tool to conduct vulnerability scans regularly to assess vulnerabilities in Emailchaser's infrastructure and systems. Critical software patches are evaluated, tested, and applied proactively.

Bounty Program

Emailchaser has an ongoing Bug Bounty Program, which allows independent security researchers to report security threats and vulnerabilities on an ongoing basis.

Customer data Backups

Emailchaser performs the following backups of its data:

        On-site backups (managed by Google, performed daily), encrypted at rest, through the Advanced Encryption Standard (AES) algorithm (further information can be found at;

        On-site backups (managed by Emailchaser, performed daily), stored in a Google Cloud Storage bucket (GCS), encrypted at rest via GCS (further information can be found at;

        Off-site backups (managed by Emailchaser, performed weekly) encrypted through the 'age' algorithm.
