Reduce the complexity of TLS management

TLS Encryption

TLS is now the standard for doing business online (94% of traffic over Google is encrypted). Plus, providing customers with the confidence their web activity is secure just makes good business sense, but TLS cert management can get complicated, fast. Deliver secure experiences to your users the way you want — without the complexity.

Benefits

Flexible TLS management at scale

Fastly can remove barriers around TLS setup and management, easing the burden on your teams. Our portfolio of TLS offerings allows every organization to deliver secure and  private experiences to their end users, designed to address a variety of customer types and needs — whether you just want to turn on TLS for a single domain or have detailed and complex security requirements.
  • Simplified management on your own terms

    With options to use our TLS certificates or bring your own, you gain full control over your certs via our UI, API, or white-glove service. Plus, auto-renewals for Fastly-managed TLS allow you to stay focused on creating excellent user experiences, not managing certs.

  • Built for performance and scale

    We’ve got you covered regardless of deployment complexity or number of web properties. With Fastly, you can provide a fast, secure experience for all your end-users — even as you grow.

  • Stay on the forefront of TLS encryption

    We provide end-to-end TLS 1.3 support that enables secure and fast experiences from the client to the origin. Plus, we support Mutual TLS (mTLS) for authenticating client certificates and securing public facing APIs, mobile apps, IOT devices and more.

TLS Encryption Frequently Asked Questions

What is TLS encryption and why is it critical for modern applications?

TLS encryption (Transport Layer Security) protects data in transit by encrypting traffic between clients and servers. It prevents eavesdropping, tampering, and man-in-the-middle attacks. For modern applications handling sensitive data, TLS encryption is foundational to security, compliance, and user trust—especially at global scale.

How does Fastly handle TLS encrypted traffic at the edge?

Fastly terminates and processes TLS encrypted traffic directly at the edge, close to users. This reduces latency while maintaining strong cryptographic security. By offloading TLS operations from origin servers, Fastly improves performance without compromising encryption strength or visibility into traffic behavior.

What makes Fastly’s TLS management different from traditional approaches?

Fastly’s TLS management is designed for speed, automation, and control. Teams can provision, rotate, and manage certificates at scale without manual workflows or downtime. TLS configuration is integrated into Fastly’s platform, enabling real-time updates and fine-grained control that traditional certificate management tools often lack.

Can Fastly help reduce the operational overhead of managing certificates?

Yes. Fastly simplifies TLS management by automating certificate issuance, renewal, and deployment. This reduces operational risk and eliminates common failure points like expired certificates—freeing security managers and engineering teams to focus on higher-value work.

How does Fastly support security managers and security teams?

Fastly provides centralized visibility and control over TLS encryption policies, making it easier for security managers to enforce standards across environments. With edge-level controls and real-time configuration, security teams can respond quickly to threats, compliance requirements, or cryptographic changes.

Does Fastly support modern TLS protocols and ciphers?

Fastly supports modern TLS protocols and strong cipher suites aligned with current security best practices. This ensures TLS encrypted traffic remains both secure and performant, while giving organizations flexibility to meet internal security policies and regulatory requirements.

How does TLS encryption impact performance on Fastly’s network?

Fastly’s edge architecture minimizes the performance overhead typically associated with TLS encryption. By handling encryption close to end users and optimizing handshake processes, Fastly delivers secure connections without sacrificing speed or user experience.

Can Fastly TLS encryption be integrated with existing security workflows?

Absolutely. Fastly’s TLS management integrates seamlessly with broader security workflows and infrastructure. It complements application security, zero trust architectures, and compliance initiatives while giving teams granular control at the edge.

Is Fastly TLS encryption suitable for large-scale, global applications?

Yes. Fastly’s platform is built for high-traffic, globally distributed applications that require consistent TLS encryption everywhere users connect. Whether you’re serving APIs, websites, or streaming content, Fastly scales TLS encrypted delivery reliably across regions.

How does Fastly help organizations stay compliant with encryption requirements?

Fastly enables organizations to enforce TLS encryption consistently, helping meet industry and regulatory requirements for data protection. With centralized TLS management and rapid configuration changes, teams can adapt quickly as compliance standards evolve.
