BrainBlog for Teleport by Jason Bloomberg
In my last article for Teleport, I discussed the problem of fragmented identities – how the scattershot assignment of machine identities leads to vulnerabilities and management overhead.
Teleport solves the problem of fragmented identities by providing a unified identity layer across both human and machine identities. The platform cryptographically secures these identities with a hardware-backed root of trust, ensuring that they can’t be lost, stolen, shared, or act anonymously.
The combination of a unified identity layer and strong identities helps organizations implement comprehensive zero trust security across their infrastructure.
And not a moment too soon – because agentic AI is here.
AI agents are another type of machine requiring an identity to operate – only now, agents can take action on their own in ways that software never has before.
As a result, Teleport’s unified identity layer is a must-have for any organization deploying agentic AI.
What is a unified identity layer?
According to Teleport, a unified identity layer integrates identity security measures across all infrastructure, including systems, virtual machines, microservices, databases, workloads, and any other piece of technology with an API, user interface, or other endpoint.
Teleport unifies identities across this variety of endpoints by centralizing the management of access policies and hardening access controls. Teleport also visually represents relationships and policies for users, groups, and various resources.
At its heart, Teleport secures this unified identity layer with a common root of trust. It then extends this common root of trust across human and machine identities – including identities for AI agents as well as model context protocol (MCP) servers.
Why is a unified identity layer so important for AI agents and MCP servers?
Organizations are only now ramping up their deployment of AI agents.
First-generation agents have limited capabilities, typically providing information as their goal but taking no further action. However, organizations are moving beyond this first generation by empowering their AI agents to take actions within the corporate environment.
Once agents have such agency, you can rest assured that hackers will take notice.
Compromising an AI agent gives a hacker more than access to sensitive data. Such compromises can potentially enable bad actors to take arbitrary actions within the corporate network.
All it takes is one compromised identity, either via phishing, credential theft, or one of the increasingly prevalent prompt engineering breaches.
MCP can actually compound the problem. One of the early applications of this protocol is to connect agents to various tools to give users the ability to interact with and control them without requiring context switching, for example, within an IDE.
What happens, then, if hackers compromise the IDE? They automatically have access to all the agents and other AI endpoints that MCP has connected to the IDE. In other words, in the bad actor’s hands, MCP acts as a force multiplier.
How Teleport secures AI agents and MCP endpoints
Without a unified identity layer, hackers can potentially leverage MCP to have free rein over any AI agent – and the systems and applications it interacts with.
Teleport secures MCP by assigning machine identities and issuing short-lived certificates to any agent or other application interacting with an MCP server. The Teleport platform enforces role-based access that ensures that AI agents and other MCP connections have authorized access at all times.
By expiring frequently, short-lived certificates minimize the risk of unauthorized access to AI agents. As a result, the validity of compromised certificates is limited, as is the potential for malicious use.
In addition, Teleport provides visibility and audit logs that ensure that all actions are observable and traceable – so even in the event of, say, a compromised insider, the organization can quickly recognize and shut down malicious behavior.
The Intellyx take
If your organization suffers from fragmented identity – by relying upon fictitious identities for non-human actors, for example – then AI agents will only add to the fragmentation.
On the other hand, if you implement a unified identity layer before deploying agents, then you will be prepared to address the additional identity-related security complexities that AI agents introduce.
If you think you can put off the transition to unifying identities, be warned: AI agents will only become more sophisticated and powerful.
It’s true that as an emerging technology, many of today’s agents have limited agency. As the technology evolves, however, it’s human nature to want to implement increasingly powerful capabilities.
The future promise of agentic AI, therefore, increases the urgency of deploying a unified identity protection layer – and in truth, any zero trust initiative generally.
The sudden rise of MCP also raises the unified identity stakes. In its first year of existence, the protocol achieved bewildering levels of adoption – despite concerns that it offers inadequate security.
As an integration protocol, furthermore, MCP’s purpose is to connect things – and thus organizations are using it to make all manner of AI-centric connections across their application landscapes.
This rapid deployment of powerful new technologies and integration-friendly protocols is playing right into bad actors’ hands. After all, there’s nothing a hacker loves more than powerful technologies with immature or poorly understood security measures.
Don’t get caught by surprise. Even if your organization has yet to dip its toe in the agentic AI waters, the time is right to put a unified identity layer in place. Don’t wait until the bad guys force your hand.
