Security at Postman

Your data security is important to us

More than 10 million users and over 500,000 companies worldwide use Postman products and access Postman services. Individuals, small, medium, and large organizations count on Postman to meet their data protection and data security needs. We have developed a comprehensive set of practices and policies to help ensure your data is secure.

Key Security Features

  • Data encryption - We use strong encryption standards to protect data both in transit between Postman clients and the Postman cloud and at rest in the production network.

    • Data in transit - All interactions use TLS with 2048-bit digital signatures, 128-bit AES encryption, and the latest recommended secure cipher suites.

    • Data at rest - Depending on its sensitivity classification, customer data is also AES-256-GCM encrypted on the server-side before storage.

  • SAML based SSO [Enterprise only] - Authenticate with and access Postman services through an identity provider of your choice with SAML 2.0 compliant single sign-on (SSO).

  • Audit logs [Enterprise only] - Track key activities related to billing, security, access, and team management with audit logs.

  • Static IP [Enterprise only] - Test IPs securely behind a firewall by a whitelisting a single, static IP address to use for monitoring.

  • Postman sessions - Protect private tokens, passwords, and credentials by storing sensitive information locally in session variables.

  • Granular role-based access control - Provide granular access to entities in Postman products with roles and permissions.

Shared Responsibility Model

While we continuously focus on doing our part to maintain high standards for security and complying with regulations, you also have a role to play in helping to ensure the security of your data. While our responsibility is to ensure that Postman products and services are safe and secure to use, yours is to ensure that you follow safe practices with the data you store within Postman. To know more about the list of things that we expect our users to be aware of during regular product usage, please read the shared responsibility model document.

For details on what information we collect from you and how we use, share, and store that information, consult our privacy policy.

Compliance and Regulations


SOC2 Type 1

Service Organization and Controls (SOC) are assurance reports which provide an industry-wide acknowledgment that a company adheres to trust service principles. For access to our SOC 2 (Type 1) report, please email us at


We comply with the European Union’s General Data Protection Regulation, which governs data protection and privacy for all individuals citizens of the European Union and the European Economic Area.

Infrastructure Security

We contract our digital hardware to cloud vendors that adhere to the applicable data regulations and compliances. Our infrastructure runs on data centers provided by Amazon Web Services (AWS), which is SOC2 and PCI Level 1 certified among others. AWS, as a platform provider, has a number of security and privacy focussed features, which we leverage wherever applicable.

Our servers run on stable, regularly patched, versions of Amazon Linux with carefully configured security groups, isolated VPC environments with well-defined network segmentation, role-based access control, and advanced web application firewall protection.

Physical and Environmental Security

We do not have in-house data centers. Amazon Web Services (AWS) manages the physical and environmental security of our data centers. Our internal security program covers physical security at our offices.

For more details, please review AWS' control and security measures.

Product and Service Security

We distribute and serve our products and services exclusively over HTTPS and secure WebSockets. All network interactions use TLS with 2048-bit digital signatures and 128-bit AES encryption. Additionally, we use HTTP Strict-Transport-Security to ensure the applications never interact with the servers on an insecure network path.

Software Security

Our applications run on the latest stable version of Node.js. We reduce the attack surface by isolating our processes via hardened containerization technology. Our security team sets architectural guidelines, conducts code reviews, and deploys every software system that can interface with customer data.

Our developers are trained with specific attention toward security. Our automated and manual code review processes look for any code that could potentially violate security policies. We have also instituted a standardized security stack that complies with software composition analysis tools.

Vulnerability Management

Our security team performs Vulnerability Assessment and Penetration Testing (VAPT) of our ongoing releases, interfacing with products and services. All vulnerabilities found during VAPTs are managed internally in our vulnerability management system. All vulnerabilities are assigned a score, using the CVSS scoring system, and an owner. We also have an internal SLA that stipulates deadlines for fixing vulnerabilities.

Employee Access

To manage employee access, we have implemented an audited security policy (IAM) that includes access control, a secure password policy, BYOD, and secure network access.

All internal services require single sign-on, with 2FA RSA Authentication. All SSH-based access has a mandatory key-file driven policy that requires storing keys securely, rotating them frequently, and logging all access to them.

Data Security

All customer data is stored in databases on Amazon RDS, which are configured securely. Data is stored with at least dual redundancy, with 15-day backups, and is accessible only within the private cloud. We have also instituted per-service access protection and isolation of data.

Depending upon its sensitivity classification, Customer data is AES-256-GCM encrypted at the on server-side before storage. Postman environment and global variables are covered in this classification and we strongly encourage using them to store authentication keys and passwords. We have also added sessions in the 6.2 release onwards of Postman. We recommend using session variables for any data that users do not want to be synced to Postman’s servers.

We maintain all internal testing and validation data in a production-stack equivalent internal stack populated with fictitious data. Postman does not distribute actual customer data for internal testing or validation purposes.

We have instituted a role-based access process to govern access to any customer data required for customer support (or otherwise). This process is audited and recorded and includes a human arbitration done by a core team. Consisting of the founders and VP of Engineering, This team validates the requirement hypothesis and ensures data is obfuscated and sanitized before communicating back to customer support or engineering. Customer data classified as sensitive is not accessible by any party except the customer.

Attack Prevention and Mitigation

We maintain intelligent, web application firewalls on our load balancers which, along with the elastic scaling capacity of our compute instances, mitigate attacks at the application layer.

We log activity across our platform, from individual API requests to infrastructure configuration changes. Logs are aggregated for monitoring, analysis, and anomaly detection and archived in vaulted storage. We implement measures to detect and prevent log tampering or interruptions. In order to determine security breaches, we monitor access patterns and network data flow patterns using automated systems that alert us in case of an anomaly. We also keep track of private contacts and public channels from our open-source and third-party technology stacks for any security-related reports. In case of a customer-reported breach, the CTO, CEO, and VP of Engineering are notified automatically and the report is responded to within a few hours as per set policies.

Incident Response

We have incident response policies and procedures to address service availability, integrity, security, privacy, and confidentiality issues. As part of our incident response procedures, we have trained our teams to:

  • Promptly respond to alerts of potential incidents

  • Determine the severity of the incident

  • Analyze and assess the extent of the incident

  • If necessary, execute mitigation and containment measures

  • Communicate with relevant internal and external stakeholders, including notifying affected customers so as to comply with relevant laws and regulations and meet contractual obligations around breach or incident notifications

  • Gather and preserve evidence for investigative efforts

  • Conduct and document a postmortem and develop a permanent triage plan

The incident response policies and processes are audited as part of our SOC 2 and other security assessments. Check out our Status page for service availability information.

Payment Processing

We process all payments using Stripe, which has been certified as a PCI Level 1 Service Provider.
