Secure infrastructure

Grammarly’s infrastructure is built to protect your data according to high industry standards.

Data hosting

Grammarly hosts data in Amazon Web Services data centers in US East and US West regions and ensures continual product availability by using native backup tools. An industry-leading infrastructure provider, AWS is certified as compliant with ISO 27001 and has received a SOC 2 (Type 2) report.

Data encryption

Grammarly encrypts all data in transit and at rest. Data transfer is protected using the industry-standard TLS 1.2 protocol, while data at rest in AWS is encrypted using AES-256 server-side encryption. Grammarly uses AWS Key Management Services for database encryption and secure key management.

Cloud platform

All components that process your data operate in Grammarly’s private network inside our secure cloud platform, and each Grammarly user’s data is isolated from other users’ data. Grammarly’s servers and network ports are behind load balancers and a web application firewall.

Grammarly thoroughly reviews all data subprocessors to conduct due diligence. Read more about the subprocessors Grammarly uses.

Security is embedded in our culture

Grammarly employees complete mandatory annual training on a wide range of privacy and security topics. In addition, our Security Champions program ensures that teams have an embedded security-focused adviser who drives team-specific security initiatives.

Grammarly adheres to the principle of least privilege—employees’ data access rights are regularly reviewed to ensure only minimum required privileges are granted. All workstations run on centrally controlled endpoint-management software that enforces security configurations and protection solutions.

Third-party validation

External penetration testing

Grammarly continually works to identify and fix security vulnerabilities in our product and infrastructure. That’s why we undergo third-party network penetration tests as well as AWS security and corporate infrastructure security assessments and audits.

Grammarly’s ongoing HackerOne bug bounty program promotes transparency and provides a channel for external security researchers to identify potential security concerns. Our team responds rapidly—and resolves these issues before they can be exploited.
