What is Open XDR?

Open XDR enables a security team to protect their cloud, on-premises, and IT/OT environments from a single platform without changing their existing security stack.

What is Open XDR ?

Open XDR is a unified, AI-powered approach to detection and response that collects and correlates data from all existing security tools to protect the entire enterprise attack surface effectively and efficiently. Open XDR, unlike “closed” XDR, works with any underlying security control, including any EDR, eliminating the need for organizations to essentially hand over the control of their security stack to any single vendor. Architecturally, Open XDR is about unifying and simplifying the entire security stack to improve detection and response radically. At any given organization, a security stack will consist of numerous capabilities like SIEM, EDR, NDR, SOAR, and more. These capabilities were never designed to work with each other, and teams spend too much time managing multiple tools, leading to today’s problems –
Too many tools, not enough people, and not the right data. That’s where Open XDR comes in to unify all capabilities, correlate alerts from individual tools into holistic incidents, and simplify by reducing administrative overhead. AI and automation come in as the only technically feasible way of protecting the entire attack surface effectively and efficiently, which is why it is a key architectural attribute of Open XDR. The outcome of Open XDR is protecting your environments from threats from a single platform versus multiple tools with weak or non-existent connections band-aiding it all together. And the outcome of Open XDR is radically improved detection and response at a price anyone can afford.

Value of Open XDR

Radical Performance

Unification of the security stack, with AI powered detection and response, translates a faster, better approach to security operations.

No Vendor Lock-in

Open XDR leverages existing security tools, not forcing you to migrate your security stack to a single vendor’s firewalls, SOAR, EDR, etc.


Simplification and consolidation of security products reduce the number of licenses, tool training, and overall capital required to run security operations.

Buyer’s Guide: Key Attributes of an Open XDR Platform

Open Architecture

Produces visibility across the entire attack surface by integrating with all your. security tools.

Normalized Data

Data from all integrated security tools are transformed into the same model so that they can be enriched and correlated for AI-powered detection and response.

AI Powered

The scale of threats faced by organizations cannot be handled with manual rules or legacy signatures. AI for automated detection and correlation is a necessary part of the Open XDR equation.

Cloud Native

Scalable, micro service based technology underpinning the platform that allows it to deploy anywhere.

Automated Response

To deliver the outcome of Open XDR, deep response actions need to be orchestrated from the same platform back into source security tools.

Low Overhead

Management of the entire Security Stack has to be simpler with an Open XDR platform. This can be measured in total licensing costs and administrative time.

Stellar Cyber’s Approach to Open XDR

While integrating with your existing security tools as part of our open platform, Stellar Cyber’s Open XDR Platform also packages together multiple capabilities, all built on core technology that enables the outcome of Open XDR – radically improved detection and response at a price enterprise’s can afford. In our view, it’s not enough for Open XDR to be “extended”, that is a marginal improvement over status quo, and today’s security environment demands something dramatically different, which is why we believe Open XDR is Everything Detection and Response.
From a technology standpoint, we believe the right approach to XDR is Open-first, partially-Native. If an Open XDR platform is only a “correlation layer” on top of existing tools including a SIEM, that does not deliver a unified experience and does not simplify the Security Stack. Conversely, a Native-only XDR platform requires an enterprise to move their entire infrastructure to one vendor. The Open-first, partially-Native approach to XDR is core to our Open XDR platform. The Stellar Cyber Open XDR Platform works with whatever you have already, gives you better visibility where you don’t yet have it, and helps you consolidate multiple capabilities under one platform if you choose to do so.
