                What is Open XDR?

                 

                So, what is open XDR? Open XDR is a vendor-inclusive and flexible approach to extended detection and response (XDR). Forrester describes open XDR, also referred to as hybrid XDR, as “an XDR platform that relies on integrations with third parties for the collection of other forms of telemetry and execution of response actions related to that telemetry.” The open XDR architecture acts as an interconnected system and provides a singular view across the enterprise by aggregating relevant telemetry data from all data sources. Unlike native XDR platforms which rely on a single vendor, open XDR platforms integrate extensively across vendors. This provides the benefit of choosing best-of-breed tools and leveraging telemetry across the entire attack surface.


                For organizations that have already made significant security investments, open XDR connects and augment those investments by ingesting and correlating data across all sources. There is no need to rip and replace existing solutions. Instead, open XDR integrates disparate tools across your security stack and prioritizes the most critical alerts. This ensures flexibility to add solutions that you may require in the future, avoiding vendor lock-in. With open XDR, you don’t have to rely exclusively on one vendor in your effort to detect and stop the adversary.


                Open XDR is designed to help SecOps teams become more efficient, with lower investment and better visibility than any other solution on the market. It provides the potential for a best-of-breed security operations experience where teams can integrate tools as they see fit.

                Features and Benefits of an Open XDR Platform

                Open, Extensible Architecture

                A comprehensive, vendor-inclusive approach to threat detection that provides better visibility across your entire attack surface by integrating threat information from your existing and future security investments. Never become locked into a single vendor.

                Cloud Native

                Modernized security that is cloud-delivered at scale for better visibility, more accurate threat detection, and simplified security operations all while delivering lower total cost of ownership.

                Unified Detection

                Multiple security tools, vendors and telemetry types, all integrated into a single detection and response platform that centralizes security data collection, correlation, and analysis.

                Automated Response

                Automated playbooks and integrations accelerate investigations and incident response by automating response actions and other manual tasks with precision and speed to mitigate risk.

                Low Overhead

                Lower total licensing costs and reduced tool sprawl save time and money, plus security staff can focus on higher-impact projects and critical incidents.

                Continuous Optimization

                More flexibility to change and optimize your telemetry sources for more efficient tools and processes and better security outcomes.

                Open XDR vs Native XDR vs SIEM


                There are also two different types of XDR platforms:

                Integrates with third-party vendors.

                Vendor-exclusive all-in-one platform.

                While XDR and Security Information and Event Management (SIEM) platforms both analyze data from multiple sources to detect and respond to cybersecurity threats, their functionality and use cases are different:

                Automatically collects and correlates security data across endpoint, network, cloud, and other systems to prevent, detect and respond to advanced threats.

                Collects, stores and reports on log data for incident response, forensics, and regulatory compliance.

                SIEM solutions are designed to support threat detection, compliance and security incident management. But as the threat landscape evolves, they are having a hard time keeping pace. SIEMs are great for collecting and analyzing large volumes of log events and other data, but rarely provide improved detection fidelity and often lack complete, automated incident response capabilities. As a result, the security industry is experiencing a shift towards XDR, which unifies security-relevant telemetry from endpoint, network, cloud, identity, and other business systems to provide full visibility across the entire IT ecosystem. XDR goes beyond the characteristics of a traditional SIEM, offering more effective security, faster workflows, and holistic incident management.

                There are, however, significant differences between XDR vendors – especially between those that offer open XDR vs. native XDR platforms. Native XDR is designed as an all-in-one platform from a single vendor. This means that all the integrations and telemetry sources are part of the solution itself, which may lead to faster deployment and shorter time to value. But as organizations grow, they often want to invest in multiple third-party and best-of-breed solutions. To achieve better visibility and integrate an XDR solution with all the security intelligence and telemetry sources in your environment, regardless of the vendor, you’ll need an open XDR platform. Other distinct differences between open XDR vs. native XDR vs. SIEM include:

                Functionality Open XDR Native XDR SIEM

                Open XDR Frequently-Asked Questions (FAQs)

                Extended detection and response (XDR) is a new approach to threat detection and response that provides holistic protection against cyberattacks. Analyst firm Gartner defines XDR as “a SaaS-based, vendor-specific, security threat detection and incident response tool that natively integrates multiple security products into a cohesive security operations system.” XDR automatically collects and correlates security data across the IT ecosystem to prevent, detect and respond to advanced threats. Learn more here.

                XDR stands for extended detection and response. The predecessor to XDR, EDR (endpoint detection and response) focused on monitoring and protecting endpoints. With data moving beyond the perimeter, XDR is necessary to extend the range of protection to not only endpoints, but also networks, servers, cloud, and other business systems.

                Open XDR is also known as hybrid XDR and integrates with third-party security vendors, as opposed to single vendor solutions, in a coordinated approach.

                Yes, open XDR is secure. In fact, open XDR may offer security teams a more complete view of the threat landscape. Organizations can augment their current security stack, and improve its output and value by layering an open XDR solution to solve their common threat prevention, detection and response needs.

                The cost of open XDR varies between vendors with a variety of pricing models. Secureworks Taegis prices by endpoint to establish a predictable pricing model.

                Open XDR as-a-service combines open XDR with Managed Detection and Response (MDR). The fully managed solution is delivered through your open XDR platform and leverages a team of security experts to investigate and respond to threats on your behalf. Secureworks delivers Taegis ManagedXDR for organizations that need to leverage a third party for 24x7 monitoring or SOC-as-a-Service capabilities.
