Open XDR vs. SIEM
Published: 2023-11-02 13:36:05

## Introduction:
The next generation of security intelligence is here, and it’s called extended detection and response (XDR). XDR is a technology that enables organizations to detect and respond to advanced threats faster, easier and with greater accuracy than ever before. It does this by unifying disparate data sources in one centralized location and providing richer visibility into threats than SIEM.

## XDR helps detect and respond to threats faster and easier than SIEM
XDR is an open framework that helps detect and respond to threats faster and easier than SIEM. 

XDR is a more powerful and flexible solution than [SIEM](https://stellarcyber.ai/platform/capabilities-ng-siem/). 

XDR is more scalable than SIEM. 

XDR is easier to use than SIEM

## XDR can unify a wide range of data that SIEM cannot
The most significant [advantage of XDR](https://stellarcyber.ai/platform/what-is-open-xdr/) over SIEM is that it can unify a wide range of data that SIEM cannot. Let’s say you want to keep an eye on your company’s IT infrastructure and systems, including the security mechanisms in place. With a SIEM system, this means gathering information from only the network [firewall](https://stellarcyber.ai/enterprise/firewall-traffic-analyzer/), intrusion detection system (IDS), anti-virus software program and intrusion prevention system (IPS). 

However, if you had access to additional sources such as data logs from other applications like HR or accounting systems; social media activity; mobile devices; remote servers or even on-premises servers—you could realize greater insight into how hackers are gaining access and infiltrating your network by tying these disparate sources together in real time. 

In addition to providing greater visibility into your environment for [detecting threats](https://stellarcyber.ai/platform/automated-threat-hunting/) across multiple dimensions at once and creating automated alerts based on incidents that have been identified during analysis, [XDR](https://stellarcyber.ai/platform/what-is-open-xdr/) also provides context around each incident so you can see not only what happened but why it happened—so next time something similar comes around again (or even better yet before!) then everyone will know exactly how best to respond — faster than ever before! XDR provides richer visibility into threats than SIEM 

## XDR provides richer visibility into threats than SIEM
XDR is designed to unify security data from multiple sources. By unifying all of your data, you can get a more complete picture of the threat landscape in your organization and make more informed decisions. XDR integrates security teams and technologies in a way that SIEM cannot 

When it comes to security, most companies will have a SIEM. However, this is only one tool in a long list of tools that need to be integrated with each other in order for the entire system to work properly. 

XDR is a unified security platform that integrates all the different technologies and data sources used by security teams so they can get a complete view of their organization’s risk posture. With XDR, you can integrate your existing tools and technologies into one single platform – which means your team has more time to focus on what’s important: protecting your business from cyber-attacks! 

XDR is the next generation of security intelligence, enabling organizations to detect and respond to advanced threats with greater speed and accuracy than ever before.
XDR is a [unified security platform](https://stellarcyber.ai/company/cybersecurity-stellar-cybers-take/) built on an open, extensible architecture that allows you to leverage your existing investments and extend them across your entire organization.

XDR puts you in control of your security ecosystem by delivering a single platform that enables you to collect data from anywhere across your enterprise, then enhance it through machine learning-based analysis. Using this intelligence, the [XDR solution](https://stellarcyber.ai/platform/what-is-open-xdr/) will automatically detect malicious activity for immediate response — providing real-time protection against advanced attacks. 

## Conclusion:
XDR is the next generation of security intelligence, enabling organizations to detect and respond to advanced threats with greater speed and accuracy than ever before. XDR enables unified visibility into all data sources, including traditional [SIEM solutions](https://stellarcyber.ai/platform/capabilities-ng-siem/), threat intel feeds and more. By combining these inputs with machine learning models that automate response actions based on contextual information such as user location or IP address; security teams can take action faster than ever before.
