Why Open XDR?

Today's Challenges of Security Operations

automated soc

Too Many Tools

Too Many Siloed Tools
Too Many Isolated Events

Blind spots, uncoordinated teams complex to operate

Not Enough People

Repetitive Mundane
Manual Tasks

Inefficient, overworked
and dispirited team

Not Right Data

Too Much Data
or Too Little Data

Too costly or coverage gaps, inaccurate results

What is Open XDR?

Open XDR is a unified, AI-powered approach to detection and response, that collects and correlates all existing security tools, to protect the entire enterprise attack surface effectively and efficiently. Open XDR is Everything Detection and Response, more than eXtended Detection and Response, because it must defend against all threats across the entire attack surface. The only way to do this is by integrating with existing security tools.

Architecturally, Open XDR is about unifying and simplifying the entire Security Stack for the purpose of radically improving detection and response. At any given enterprise, 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, which is what leads to the problems of today – too many tools, not enough people, not right data. That’s where Open XDR comes in –

unify all capabilities together, correlate alerts from individual tools into a holistic incident, simplify by reducing administrative overhead. AI and automation comes 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 enterprise from threats from a single platform versus multiple tools that have weak or non-existent connections band-aiding it all together. And the ultimate outcome of Open XDR is radically improved detection and response at a price enterprise’s can afford.

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 a security operations program.

Buyer's Guide: Key Attributes Of An Open XDR Platform

network security

Open Architecture

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

network traffic analysis

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 enterprises 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.
