Enhancing Security and Connectivity: AWS Certificate Manager Now Seamlessly Integrates with AWS PrivateLink
Seattle, WA – August 15, 2025 – Amazon Web Services (AWS) today announced a significant advancement in the security and manageability of SSL/TLS certificates with the general availability of AWS Certificate Manager (ACM) support for AWS PrivateLink. This powerful new integration empowers customers to provision, manage, and deploy certificates for their private applications and resources entirely within their Virtual Private Cloud (VPC) network, without exposing sensitive traffic to the public internet.
For organizations increasingly prioritizing data privacy and network segmentation, this announcement marks a pivotal moment. AWS PrivateLink provides private connectivity between VPCs, AWS services, and on-premises applications. By enabling ACM to leverage PrivateLink, customers can now securely access ACM APIs and provision certificates for services hosted within their VPCs, such as internal load balancers, web servers, and other custom applications, with enhanced security and control.
Previously, managing certificates for resources that were not directly exposed to the public internet required more complex network configurations or reliance on public endpoints. The introduction of PrivateLink support for ACM eliminates these complexities, offering a streamlined and inherently more secure approach.
Key Benefits of ACM Support for AWS PrivateLink:
- Enhanced Security Posture: By keeping certificate management traffic within your private network, the risk of exposure to the public internet is significantly reduced. This is particularly crucial for organizations operating in highly regulated industries or those with stringent security compliance requirements.
- Simplified Network Architecture: Customers no longer need to configure complex firewall rules or public endpoints to access ACM for their private resources. The direct, private connection provided by PrivateLink simplifies network design and reduces the attack surface.
- Improved Performance and Reliability: Private connectivity often translates to more consistent and predictable performance, as traffic avoids the latency and potential congestion of the public internet.
- Seamless Integration: ACM’s PrivateLink support is designed for effortless integration into existing AWS environments. Customers can easily enable PrivateLink endpoints for ACM and begin securely managing their certificates with minimal configuration changes.
- Cost-Effectiveness: By avoiding data transfer costs associated with traversing the public internet for API calls, customers can potentially see cost savings in their network operations.
This advancement underscores AWS’s commitment to providing robust and secure solutions for its customers. The ability to manage critical security assets like SSL/TLS certificates within a private network, facilitated by AWS PrivateLink, empowers businesses to build and deploy applications with greater confidence and agility.
“We are thrilled to offer AWS Certificate Manager support for AWS PrivateLink,” said [Hypothetical AWS Spokesperson Name and Title]. “This feature addresses a critical customer need for secure, private certificate management within their VPC environments. It aligns with our ongoing dedication to providing comprehensive security tools that empower our customers to protect their sensitive data and applications.”
To get started, customers can create an interface VPC endpoint for AWS Certificate Manager in their VPC, which allows their services to communicate with ACM privately. Detailed guidance and documentation are available on the AWS documentation portal.
This integration represents a significant step forward in securing and simplifying certificate management for private applications on AWS, reinforcing the platform’s position as a leader in cloud security and innovation.
