The 10 Coolest XDR Security Companies To Know In 2021

From dramatically reducing alerts and improving the productivity of security teams to facilitating automated incident response, here’s a look at 10 XDR security companies looking to dominate this emerging market.


The Brains Of The Operation

Extended detection and response (XDR) centralizes security data by combining security information and event management (SIEM); security orchestration, automation, and response (SOAR), network traffic analysis (NTA), and endpoint detection and response (EDR). Obtaining visibility across networks, cloud and endpoint and correlating threat intelligence across security products boosts detection and response.

An XDR system must have centralized incident response capability that can change the state of individual security products as part of the remediation process, according to research firm Gartner. The primary goal of an XDR platform is to increase detection accuracy by corelating threat intelligence and signals across multiple security offerings, and improving security operations efficiency and productivity, Gartner said.

XDR offerings will appeal to pragmatic midsize enterprise buyers that do not have the resources and skills to integrate a portfolio of best-of-breed security products, according to Gartner. Advanced XDR vendors are focusing up the stack by integrating with identity, data protection, cloud access security brokers, and the secure access service edge to get closer to the business value of the incident.

From dramatically reducing alerts and improving the productivity of security teams to facilitating automated incident response and protecting users, applications and data, here’s a look at 10 XDR security companies fighting for a leadership position in this emerging market.

Cisco Systems

Cisco has included XDR capabilities as part of each security product’s existing subscription since 2018, with more than 11,000 customers adopting SecureX threat response as part of their daily security operations to be more productive. The company in 2020 simplified breach defense by natively connecting detection to response with capabilities integrated within each other’s product consoles.

The company’s network detection and response and endpoint detection and response technologies have been natively integrated before XDR was even coined, containing 70 percent more malicious intent and risk exposure by connecting many types of machine learning-enhanced analytics. Cisco said it can also reduce detection time by 95 percent with proactive threat hunting and vulnerability management.

Cisco Secure Endpoint can reduce incident response time by up to 85 percent by accelerating the detection and automating the response to threats, according to the company. And Cisco Secure Network Analytics reduces false positives by enabling behavioral detection with agentless visibility across the network and cloud.


CrowdStrike’s XDR strategy is rooted in combining endpoint events with network visibility, account and identity insight, and massive telemetry from all workloads, regardless of where they are—on-premises, in the cloud or even deployed in a container. The company can correlate telemetry from all types of workloads together with identity and asset information, according to CrowdStrike.

The company bought Humio for $400 million in March to better ingest and analyze both unstructured and semi-structured data to address challenges within increasingly sophisticated DevOps and DevSecOps environments. Combining CrowdStrike’s real-time analytics and smart filtering with Humio’s quick log management and index-free data ingestion will further accelerate XDR, CrowdStrike said.

Endpoint security telemetry from CrowdStrike Falcon can also be contextualized and correlated with other existing data sources and security tools on cloud, network and SaaS applications, CrowdStrike said. The company will be able to enrich native applications in the CrowdStrike Store to leverage intelligence and insight for full XDR and automated workflow, enabling partners to take autonomous actions.

Cybereason XDR correlates all attack activity and presents the intelligence as an intuitive malicious operations visualization that significantly decreases investigation and remediation periods.

Cybereason XDR recognizes the most subtle signs of compromise derived from across the whole of an organization’s network and delivers enhanced correlations across both Indicators of Compromise and Indicators of Behavior. The product also reduces mean time to respond with automated and guided one-click mitigation from a single console across all networks without the need to craft complex queries.


Fortinet’s FortiXDR debuted in January 2021 to reduce complexity, speed detection and coordinate response to cyberattacks across the organization, leveraging artificial intelligence for the investigation effort critical to incident response. The tool can fully automate security operations processes typically handled by experienced security analysts to mitigate threats faster across the broad attack surface.

The offering starts by leveraging the diverse security information shared across the Fortinet Security Fabric for correlation and analysis, converting them into high-fidelity security incidents. These incidents are then investigated by the artificial intelligence engine to come to a final threat classification and scope, according to Fortinet.

Finally, the best possible contextual responses are defined and can be automatically implemented by FortiXDR to quickly remediate confirmed incidents. FortiXDR also enables organizations to reduce the risk of missing potentially crippling cyberattacks like ransomware and phishing by ingesting telemetry that increases the chance of detecting and properly classifying attacks, according to Fortinet.


McAfee MVision XDR debuted in October and offers cloud-based advanced threat management with coverage across the attack life cycle, prioritization to protect what matters, easy orchestration and efficient response.
