SOLUTION BRIEF

Powering MDR with Open XDR
360° Threat CoverageHow XDR Enables MDR•

Comprehensive coverage: 360-degree visibility, high-ﬁdelity
detection, and fast remediation across multiple solutions (networkﬁrewall, web application ﬁrewall, email security, etc.) and in hybrid
environments (on-premises, network and multi-cloud).

•Better Detections: The Stellar Cyber and ActZero AI-engines deliveradvanced analytics, multi-variate and multi-vector correlations toimprove signal-to-noise alert ratios, and automate response.

Comprehensive Cloud& Network Detections

Business Challenges
Cyber crimes are constantly evolving with new tactics and techniques –and businesses of all sizes struggle to keep pace. Indiscriminately adding
tools and resources to solve the problem simply won’t work.
Many tools like security information and event management (SIEM),
Network Detection and Response (NDR), and even Endpoint Detection
and Response (EDR) are very good at improving a businesses security
posture, or even meet compliance requirements. Each was designed togive companies basic detections, a centralized view of security events,
some place to help see, detect, and respond to threats from the single
vector sources that populate them.

If only adversaries worked that way.
In reality, adversaries search for “open doors and windows” on yournetwork that can be exploited, then execute attacks against them.
These holistic attacks can originate anywhere a vulnerability exists,
whether that be the cloud, a server, a workstation endpoint, or a mobiledevice. From there, the attack can spread like wildﬁre, jumping acrossvulnerabilities and platforms until many endpoints and cloud systems
are compromised.

Fewer Alerts
Stellar Cyber’s focus on highﬁdelity detections aligns withActZero’s ultimate goal ofdelivering zero needless alerts

Solution Overview
Both ActZero and Stellar Cyber understand the inefficiency of using
siloed tools with disparate management systems to solve for cybersecurity
challenges that operate with little regard for technology boundaries.
In building up its detection capabilities, ActZero chose Stellar Cyber for
its ability to integrate XDR detections – particularly its network and clouddetections – into its data lake. ActZero correlates and analyzes data from
Stellar Cyber with its existing security tools and own endpoint sensors toadd additional detections built off of Stellar’s out-of-the-box detections,and to expand its detection and response capabilities.

Stellar Cyber provides ActZero with dozens of networkand cloud anomaly and behavioral detections, including:•ATO and unauthorized login detections that use Stellar
Cyber’s machine learning (anomaly detection specifically),
and compares user behavior to typical behavior.

Use of the Stellar Cyber Open XDR environment allowsActZero Threat Hunters to complete ﬁrewall threathunting and create appropriate tickets, improving
analyst productivity by piecing together attacks fromacross the entire IT infrastructure.

ActZero is a cybersecurity startup purpose-built forsmall- and mid-size businesses. Our intelligent managed
detection and response service provides 24/7 monitoring,protection and response support that goes well beyond
other third-party software solutions. Our teams of data
scientists leverage cutting-edge technologies like AI and
ML to scale resources, identify vulnerabilities and eliminate
more threats in less time. We actively partner with ourcustomers to drive security engineering, increase internal
efficiencies and effectiveness and, ultimately, build amature cybersecurity posture. Whether shoring up anexisting security strategy or serving as the primary line ofdefense, ActZero enables business growth by empowering

Stellar Cyber’s Open XDR platform delivers Everything
Detection and Response by ingesting data from all tools,
automatically correlating alerts into incidents acrossthe entire attack surface, delivering fewer and higherﬁdelity incidents, and responding to threats automaticallythrough AI and machine learning. Our XDR Kill Chain™,
fully compatible with the MITRE ATT&CK framework,
is designed to characterize every aspect of modern attacks
while remaining intuitive to understand. This reduces
enterprise risk through early and precise identiﬁcation
and remediation of all attack activities while slashing costs,
retaining investments in existing tools and accelerating
analyst productivity. Typically, our platform delivers an 8X
