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.

The Case for Open XDR

Open XDR Emerged to Meet Today's Security Operations Challenges

Network traffic analysis

Hard to Use Products

  • Products are hard to tune properly
  • Maintaining products requires manual processes
  • Many products designed for expert users
  • Even when implemented correctly, the products work in silos
Next Gen SIEM

Not Enough People

  • Challenging to find experienced security analysts
  • Key analysts on the team are in high demand
  • Team members working well outside their comfort zone
  • Redundant manual tasks
Open XDR

Data Avalanche

  • Every security product generates tons of alerts
  • With overlapping capabilities, many alerts are redundant
  • Security analysts find out late that they are working on the same incident
  • Easy for an attack to go unnoticed in sea of data
SIEM application

Slow to Act

  • Too many alerts to investigate
  • Manual processes drive down efficiency
  • Attackers have more time to carry out their goals
  • Very little security teams can do to change things using current technology

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.

Radical Performance

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

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

Network Detection and Response Platform

Open Architecture

Produces visibility across the entire
attack surface by integrating with all
your security tools.
Network detection and response 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.
User Behavior Analytics

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.
Firewall Traffic Analysis

Cloud Native

Scalable, micro service based
technology underpinning the
platform that allows it to deploy
Automated threat hunting

Automated Response

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

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 platformis
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.
