Both AWS Systems Manager (SSM) Session Manager and Delinea are solutions for gaining remote access to critical infrastructure. Yet, while they share some of the same capabilities required of an enterprise access management platform, the execution and the ultimate goals they accomplish for security and compliance teams are very different.
While AWS provides an effective solution for specific AWS session access requirements, Delinea uses a fine-grained approach that emphasizes actions rather than access from the beginning of a session through the end.
Let’s review the details of both solutions to understand why Delinea is the best choice for your organization’s overall access management strategy.
AWS SSM Session Manager is a remote access management service that allows users to establish remote SSH and RDP sessions to Linux, macOS, and Windows servers hosted on AWS or on-prem, without maintaining bastion hosts or opening inbound firewall ports. Sessions can be browser-based or initiated with the AWS CLI.
Delinea Zero Trust Privileged Access Management Platform (PAM) allows IAM and security teams to manage the access lifecycle to critical infrastructure comprehensively. Delinea helps manage access to cloud-based and on-prem infrastructure, from legacy to cloud-native, with dynamic access workflows and continuous context-based authorization, in a frustration-free way while maintaining a strong security posture. It supports the needs of IT and related teams, including
While ostensibly seeking to perform similar operations, these two solutions approach the task of access management and control through very different methods. The differences in approaches govern what each is able to achieve, as you can see in this outline of key solution elements.
Delinea does not require agents to be installed on end resources. This means fewer administrative headaches in managing the solution and faster time-to-value for the product. Session Manager requires the installation of the SSM agent for the operating systems supported (Linux, macOS, and Windows), which complicates the ongoing maintenance of the managed nodes.
Session Manager is limited to SSH and Windows PowerShell sessions (RDP is available via Systems Manager Fleet Manager). Delinea is built for the modern stack, with cloud-native support for dozens of protocols. It lets you monitor and manage access to servers (SSH and RDP), multiple clouds (including AWS), Kubernetes clusters, and many different database types, from legacy to cloud-native. It supports almost everything in your environment.
Session Manager requires that access to go through a web browser or via the AWS CLI. Delinea does not force the use of a particular client or a web browser to connect to the supported resources. The user can access resources using their favorite GUI or CLI clients, allowing for maximum flexibility without impacting productivity.
Session Manager relies on IAM permissions only. Delinea, on the other hand, employs fully dynamic workflows, whether from the administrative UI, Slack, or ServiceNow. This allows for Just-in-Time access to critical infrastructure, removing standing privileges, which decreases the risk of insider threats.
Delinea is a proxy that combines authentication, authorization, networking, and observability capabilities for your environment. This architecture simplifies access workflows by providing low-friction connectivity to virtually every piece of infrastructure in your stack. A high degree of security posture is maintained with fully encrypted tunnels, visibility of every session, and dynamic credential injection between the Delinea Gateway and your vault of choice for all supported protocols and resource types. This ensures that end-users are never exposed to credentials. Delinea also supports end-to-end passwordless authentication with certificate-based authentication for SSH and RDP, and IAM authentication support for EKS and RDS PostgreSQL (Aurora and regular PostgreSQL).
The Strong Policy Engine allows continuous Zero-Trust access to critical infrastructure. Policies are managed centrally, while being enforced in a distributed way on enforcement points near the resources being accessed. This allows for continuous, real-time assessment of a user’s security posture, and uses that context to allow, deny, or challenge a user’s session from continuing. The Zero Policy Engine also implements policies with fine-grained permissions of actions on resources.
Session Manager provides a limited set of protocols and features, which is sufficient for AWS-only implementations. Delinea, by contrast, allows for more complete coverage of all resource types across more environments–from legacy infrastructure to cloud-native and from on-prem to Cloud.

(1) On-prem, cloud-managed, and self-managed;
(2) Delinea streams logs directly to S3, where they can easily be imported into CloudWatch;
(3) SSM requires a web browser or AWS-CLI clients.
Delinea is built for an organization's entire technical staff, not just developers. It’s easy for end users to adopt because it seamlessly integrates with existing tools and workflows, including identity providers and vault solutions. Delinea has superior reliability and a cost-effective pricing model.
