Product security


Single Sign-on (SSO) allows you to authenticate users in your own systems without requiring them to enter additional login credentials If you’re using password based authentication, you can turn on 2-factor authentication (2FA) More details on our docs.


We enable permission levels within the app to be set for your teammates. Permissions can be set to include app settings, billing, user data or the ability to send or edit messages.

Password and Credential Storage

Limecall enforces a password complexity standard and credentials are stored using a PBKDF function (bcrypt).


We have uptime of 99.9% or higher. You can check our past month stats at

Customer Best Practices

There are simple steps you can take to increase the security of your app. Check out the Staying Secure section on our docs site.

Network and application security

Data Hosting and Storage

Limecall services and data are hosted in Amazon Web Services (AWS) facilities (us-east-1) in the USA.

Failover and DR

Limecall was built with disaster recovery in mind. All of our infrastructure and data are spread across 3 AWS availability zones and will continue to work should any one of those data centers fail.

Virtual Private Cloud

All of our servers are within our own virtual private cloud (VPC) with network access control lists (ACLs) that prevent unauthorized requests getting to our internal network.

Back Ups and Monitoring

On an application level, we produce audit logs for all activity, ship logs to Graylog for analysis and use S3 for archival purposes. All actions taken on production consoles or in the Limecall application are logged.

Permissions and Authentication

Access to customer data is limited to authorized employees who require it for their job. Limecall is served 100% over https. Limecall runs a zero-trust corporate network. There are no corporate resources or additional privileges from being on Limecall’s network. We have Single Sign-on (SSO), 2-factor authentication (2FA) and strong password policies on GitHub, Google, AWS and Limecall to ensure access to cloud services are protected.


All data sent to or from Limecall is encrypted in transit using 256 bit encryption. Our API and application endpoints are TLS/SSL only and score an “A+” rating on Qualys SSL Labs‘ tests. This means we only use strong cipher suites and have features such as HSTS and Perfect Forward Secrecy fully enabled. We also encrypt data at rest using an industry-standard AES-256 encryption algorithm.

Pentests, Vulnerability Scanning and Bug Bounty Program

Limecall uses third party security tools to continuously scan for vulnerabilities. Our dedicated security team responds to issues raised. Twice yearly we engage third-party security experts to perform detailed penetration tests on the Limecall application and infrastructure. Limecall also runs a ‘bug bounty’ program with Bugcrowd, which gives security researchers a platform for testing and submitting vulnerability reports.

Incident Response

Limecall implements a protocol for handling security events which includes escalation procedures, rapid mitigation and post mortem. All employees are informed of our policies.
