Managed XDR Services: Extended Threat Protection
Cross-domain threat detection across endpoints, networks, cloud workloads, identity systems, and email, operated by a dedicated security team so your organization catches multi-stage attacks that isolated tools miss.
What Is XDR? Understanding Extended Detection and Response
Extended detection and response (XDR) is a security architecture that collects and correlates telemetry from multiple protection layers, including endpoints, networks, cloud environments, identity platforms, and email gateways, into a single detection and investigation platform. Traditional security tools operate in silos. Your endpoint detection and response (EDR) agent sees process execution on a workstation. Your firewall sees network traffic. Your cloud security posture manager sees misconfigurations in AWS or Azure. Each tool generates its own alerts in isolation, and none of them can connect those signals into a coherent attack story.
XDR solves that visibility gap. When an attacker sends a phishing email that bypasses the email gateway, installs a fileless loader on an endpoint, moves laterally through Active Directory, and exfiltrates data to an external cloud storage service, an XDR platform sees every stage of that kill chain as one correlated incident rather than four unrelated alerts spread across four different consoles. That correlation capability is what makes XDR security fundamentally different from EDR, SIEM, or standalone network detection tools.
The concept emerged because organizations were drowning in disconnected security alerts. The average security operations center receives more than 11,000 alerts per day, according to industry research, and analysts can investigate only a fraction of them. XDR reduces alert fatigue by grouping related signals into a single incident, enriching that incident with threat intelligence and behavioral context, and presenting it to analysts with a complete attack timeline. Instead of manually pivoting between five different consoles to piece together what happened, analysts start with the full picture.
XDR differs from EDR in scope. EDR focuses exclusively on endpoints, monitoring file activity, process execution, registry changes, and network connections on workstations and servers. XDR extends that visibility to every domain in the environment. It differs from SIEM in approach: while SIEM collects logs and requires analysts to write correlation rules, XDR solutions use built-in detection models and machine learning to correlate events automatically. For a detailed technical comparison, see our guide on XDR vs. EDR.
Why Managed XDR? Technology Alone Is Not Enough
XDR platforms are powerful, but they are not autonomous. Every XDR deployment requires skilled analysts to tune detection rules, investigate correlated incidents, build response playbooks, integrate new telemetry sources, and hunt for threats that automated detections miss. Most XDR vendors acknowledge this directly: their platforms are designed to amplify human analysts, not replace them.
The challenge is staffing. Building an internal team capable of operating an XDR platform 24/7 requires a minimum of six full-time security analysts, a detection engineer, a threat intelligence analyst, and an incident response lead. At current market rates, that team costs between $900,000 and $1.4 million annually in salary alone, before accounting for benefits, training, tooling licenses, and management overhead. For organizations with fewer than 1,000 employees, that investment is nearly impossible to justify.
Even organizations that can afford the headcount face a retention crisis. The cybersecurity industry experiences annual turnover rates above 30%, and SOC analysts report the highest burnout rates in the field. When your senior detection engineer leaves, the institutional knowledge they built, the custom correlation rules they wrote, and the threat hunting hypotheses they were pursuing walk out the door with them. Rebuilding that capability takes six to twelve months, during which your XDR platform runs at diminished effectiveness.
Managed XDR eliminates these constraints by combining the XDR technology platform with a dedicated external security team that operates it around the clock. Your organization gets the cross-domain visibility, AI-powered correlation, and automated response capabilities of XDR without needing to recruit, train, and retain the specialized talent required to run it. The managed XDR provider maintains the detection logic, tunes alert thresholds, conducts proactive threat hunting, and executes incident response procedures on your behalf.
This model delivers results faster. A self-managed XDR deployment typically requires three to six months of tuning before it reaches operational maturity. A managed XDR provider brings pre-built detection libraries, proven response playbooks, and years of operational experience across hundreds of client environments, reducing time to value to weeks rather than months.

PTG's Managed XDR Service: What You Get
Petronella Technology Group delivers managed XDR as a fully operated security service. We deploy the XDR platform, integrate every telemetry source in your environment, build and maintain detection rules, operate the SOC, and handle incident response end to end. Here is exactly what the service includes.
Multi-Domain Telemetry Collection
We connect every data source in your environment to the XDR platform: endpoint agents, network sensors, cloud API integrations (AWS, Azure, GCP), identity providers (Active Directory, Entra ID, Okta), email security gateways, and SaaS applications. Every log, event, and alert feeds into a unified data lake where correlation happens automatically.
AI-Powered Correlation Engine
The XDR platform uses machine learning models trained on millions of real-world attack patterns to correlate events across domains. When a suspicious authentication event in Azure AD is followed by unusual endpoint behavior and an anomalous outbound network connection, the platform links those signals into a single high-confidence incident rather than generating three separate low-priority alerts.
Automated Response Playbooks
Pre-built and custom response playbooks execute containment actions within seconds of detection. Playbooks can isolate a compromised endpoint, disable a compromised user account, block a malicious IP across all firewalls, quarantine a phishing email from every mailbox, and create a forensic snapshot for investigation, all without waiting for human approval on routine actions.
24/7 Expert Monitoring
Our security operations center is staffed around the clock by experienced analysts who triage, investigate, and respond to every alert the XDR platform generates. Tier 1 analysts handle initial triage and enrichment. Tier 2 analysts conduct deep investigations on escalated incidents. Tier 3 engineers perform advanced threat hunting and forensic analysis.
Proactive Threat Hunting
Our threat hunting team develops and executes hunt hypotheses based on current threat intelligence, MITRE ATT&CK techniques, and patterns observed across our client base. Threat hunting goes beyond automated detections to find adversaries who have evaded existing rules, using behavioral analysis, anomaly detection, and adversary emulation techniques.
Incident Response and Remediation
When a confirmed threat is identified, our incident response team executes a structured response process: contain the threat, eradicate the attacker's access, recover affected systems, and deliver a detailed post-incident report with root cause analysis and recommendations to prevent recurrence. Our team coordinates with your internal IT staff and leadership throughout the process.
5 Domains of XDR Protection
XDR security derives its strength from covering every attack surface in your environment. Each domain provides unique telemetry that, when correlated with the others, reveals threats that single-domain tools cannot detect. Here are the five domains that PTG's managed XDR service monitors and protects.
Workstations, servers, laptops, and mobile devices. Endpoint telemetry includes process execution, file system activity, registry changes, driver loading, memory injection, and local network connections. This is where most attacks execute their payload, and endpoint visibility is the foundation of any XDR deployment. Our managed XDR service deploys and operates endpoint agents across your entire fleet with continuous monitoring and automated isolation capabilities.
East-west and north-south network traffic, DNS queries, proxy logs, and firewall events. Network telemetry reveals lateral movement, command-and-control communication, data exfiltration attempts, and connections to known malicious infrastructure. XDR correlates network anomalies with endpoint behavior to detect attacks that neither domain would flag on its own, such as a legitimate process making unusual outbound connections to a newly registered domain.
AWS, Azure, Google Cloud, and SaaS application environments. Cloud telemetry includes API calls, configuration changes, resource provisioning, access policy modifications, and storage access patterns. Cloud misconfigurations are the initial access vector in 23% of breaches. XDR integrates with cloud-native security tools to detect unauthorized access, privilege escalation, cryptomining, and data exposure in real time across multi-cloud architectures.
Active Directory, Entra ID (Azure AD), Okta, and other identity providers. Identity telemetry includes authentication events, privilege escalation, group membership changes, service account activity, and impossible travel detections. Compromised credentials are involved in 86% of breaches. XDR correlates identity events with endpoint and network telemetry to detect credential theft, pass-the-hash attacks, Kerberoasting, and account takeover attempts before attackers establish persistence.
Inbound and outbound email, attachment analysis, URL scanning, and sender reputation. Email remains the primary initial access vector for 91% of cyberattacks. XDR extends email security beyond gateway-level filtering by correlating email events with endpoint and identity telemetry. When a user clicks a link in a phishing email, XDR tracks the subsequent endpoint activity, credential usage, and network connections to detect the full attack chain from initial click to data access.

Organizations evaluating XDR solutions face a fundamental decision: operate the platform internally or partner with a managed XDR provider. Both approaches deliver the same cross-domain detection capability, but the operational requirements, costs, and timelines differ substantially. The following comparison breaks down the key factors.
| Factor | In-House XDR | Managed XDR (PTG) |
|---|---|---|
| Annual Cost | $900K-$1.4M+ (staff, tools, infrastructure) | Predictable monthly fee, typically 60-70% less |
| Staffing Requirement | 6-10 FTE analysts, engineers, and managers | Zero additional hires required |
| Time to Operational Maturity | 3-6 months (hiring, training, tuning) | 2-4 weeks (pre-built detections, proven playbooks) |
| Detection Coverage | Limited by team expertise and available time | Continuously updated from threat intel across hundreds of environments |
| Threat Hunting | Ad hoc, dependent on team capacity | Dedicated hunt team with scheduled and ad hoc operations |
| Staff Turnover Risk | High: 30%+ annual turnover in cybersecurity | Eliminated: provider manages team continuity |
| After-Hours Coverage | Requires on-call rotations or additional shifts | 24/7/365 included in service |
| Technology Updates | Your team manages platform upgrades and integrations | Provider handles all maintenance, updates, and new integrations |
For organizations with fewer than 2,000 employees, managed XDR delivers superior detection outcomes at a fraction of the cost. The economies of scale that a managed provider achieves by operating XDR across hundreds of client environments, sharing threat intelligence, and amortizing tooling costs across a large customer base make it virtually impossible for a mid-market organization to match those capabilities internally. Our SOC as a Service offering provides the same operational model for organizations that need dedicated security operations without building their own center.
How PTG's Vendor-Agnostic Approach Delivers Better XDR Outcomes
Several large managed detection and response providers, most notably Arctic Wolf with their Aurora platform, take a proprietary approach to XDR. They require you to adopt their platform, their sensors, their agents, and their data formats. Once deployed, switching providers means ripping out the entire security stack and starting over. This vendor lock-in gives the provider leverage over pricing, feature prioritization, and contract terms that work in their favor rather than yours.
Petronella Technology Group takes the opposite approach. Our managed XDR service is vendor-agnostic, meaning we work with the best-of-breed tools that fit your environment rather than forcing you onto a single proprietary platform. If your organization already runs SentinelOne on endpoints, we integrate that telemetry. If you use CrowdStrike Falcon, we work with it. If your cloud security is built on Microsoft Defender for Cloud, we incorporate those signals. We operate across platforms rather than replacing them.
This approach delivers three concrete advantages. First, you keep tools that are already deployed, configured, and understood by your internal team, which protects your existing investment and avoids the disruption of a full-stack replacement. Second, you get the best tool for each domain rather than accepting a single vendor's attempt to be adequate at everything. The best endpoint agent and the best network detection tool rarely come from the same vendor. Third, you retain the freedom to change any component at any time without renegotiating your entire security contract.
Our detection engineers build correlation logic that spans these heterogeneous tools, using open standards like STIX/TAXII for threat intelligence sharing and normalized data formats for cross-platform event correlation. The result is XDR-level visibility and correlation across your actual security stack, not a theoretical stack that a vendor wishes you would adopt. This is the same philosophy that drives our broader managed detection and response program: put the client's security outcomes first, not the vendor's sales targets.
We have integrated managed XDR telemetry from the following platforms among others: SentinelOne Singularity, CrowdStrike Falcon, Microsoft Defender for Endpoint, Microsoft Defender for Cloud, Palo Alto Networks Cortex, Cisco SecureX, Fortinet FortiXDR, AWS GuardDuty, Azure Sentinel, Google Chronicle, and Okta. Whatever combination your organization runs, we correlate the data and operate the detections.
XDR for Compliance: How Cross-Domain Visibility Maps to Framework Requirements
Compliance frameworks mandate specific security monitoring, detection, and response capabilities that XDR is uniquely positioned to satisfy. Because XDR collects telemetry from every layer of the environment and maintains correlated audit trails, it provides the evidence and operational controls that auditors and assessors require. Here is how managed XDR maps to the most common compliance frameworks PTG's clients must satisfy.
CMMC 2.0 (Cybersecurity Maturity Model Certification): CMMC Level 2 requires implementation of all 110 NIST SP 800-171 controls. XDR directly supports control families including Audit and Accountability (AU), Incident Response (IR), System and Communications Protection (SC), and System and Information Integrity (SI). The cross-domain audit trail that XDR maintains satisfies AU-2 (event logging), AU-6 (audit review and analysis), and AU-12 (audit generation). Automated response capabilities map to IR-4 (incident handling) and IR-6 (incident reporting). Our CMMC compliance services combine managed XDR with documentation and assessment preparation.
HIPAA (Health Insurance Portability and Accountability Act): The HIPAA Security Rule requires covered entities to implement technical safeguards including audit controls (45 CFR 164.312(b)), access controls, and integrity controls. XDR provides continuous monitoring of all systems that store, process, or transmit electronic protected health information (ePHI), generates the audit logs required for HIPAA compliance reviews, and detects unauthorized access attempts in real time. The incident detection and response capability directly supports the HIPAA Breach Notification Rule by identifying potential breaches early enough to contain them before reportable data loss occurs.
PCI DSS 4.0 (Payment Card Industry Data Security Standard): PCI DSS Requirement 10 mandates logging and monitoring of all access to network resources and cardholder data. Requirement 11 requires regular testing of security systems and processes. XDR satisfies these requirements by collecting and correlating logs from every system in the cardholder data environment, detecting unauthorized access attempts, and providing the continuous monitoring capability that PCI DSS 4.0 emphasizes more heavily than previous versions.
SOC 2 (Service Organization Control 2): SOC 2 Trust Services Criteria for Security (CC6, CC7) require organizations to detect and respond to security events that could affect the confidentiality, integrity, and availability of customer data. XDR provides the detection, investigation, and response capabilities that map directly to CC7.2 (monitoring system components for anomalies) and CC7.3 (evaluating security events). The correlated incident timelines that XDR produces serve as audit evidence demonstrating that security monitoring is continuous and comprehensive.
Industries We Serve with Managed XDR
Our managed XDR service protects organizations across industries where regulatory requirements, sensitive data, and high-value targets make advanced threat detection essential rather than optional. PTG has delivered cross-domain security operations to organizations in the following sectors, each with tailored detection rules and compliance reporting aligned to their specific framework obligations.
Healthcare and Life Sciences: Healthcare organizations face unique XDR requirements because their environments include clinical systems, medical devices, and research databases alongside standard IT infrastructure. Our managed XDR service monitors ePHI access patterns, detects anomalous queries against electronic health record systems, and correlates medical device network activity with endpoint and identity telemetry to detect threats that target the intersection of IT and clinical technology. Detection rules are tuned to HIPAA requirements and common healthcare attack patterns including ransomware targeting backup systems and credential theft targeting clinician accounts.
Financial Services: Financial institutions are high-value targets for both organized cybercrime groups and nation-state actors. Our managed XDR deployment for financial services clients includes specialized detection rules for business email compromise, wire transfer fraud, account takeover attacks, and insider threats. We correlate trading platform telemetry, core banking system logs, and customer-facing application activity with endpoint and network data to detect fraud and security incidents across the full technology stack.
Defense Contractors: Organizations handling Controlled Unclassified Information (CUI) under DFARS 252.204-7012 and CMMC 2.0 face the strictest monitoring and incident reporting requirements of any sector. Our managed XDR service for defense contractors includes CUI-aware detection rules, NIST 800-171 compliance reporting, and incident response procedures that satisfy the 72-hour reporting requirement to the Defense Industrial Base Cybersecurity (DIB CS) program. Every detection, investigation, and response action is logged and documented to support CMMC assessment evidence collection.
Legal and Law Firms: Law firms hold privileged client information that makes them attractive targets for espionage, competitive intelligence gathering, and ransomware. Our managed XDR service monitors document management systems, email communications, and remote access patterns to detect unauthorized access to case files and client data. We implement ethical wall enforcement monitoring that alerts when access patterns cross matter boundaries, and we detect data exfiltration attempts that target legal work product.
Manufacturing: Manufacturing environments present the challenge of converged IT and OT (operational technology) networks. Our managed XDR service extends visibility into industrial control systems, SCADA networks, and IoT devices alongside traditional IT infrastructure. We detect attacks that pivot from IT networks into OT environments, monitor for unauthorized firmware changes on industrial controllers, and correlate network anomalies in production environments with endpoint behavior on engineering workstations.

Talk to Our XDR Team Call 919-348-4912Managed XDR: Frequently Asked Questions
What is the difference between managed XDR and managed detection and response (MDR)?
Managed detection and response (MDR) is a broader category that describes any outsourced threat detection and response service. Managed XDR is a specific type of MDR that uses an XDR platform as its technological foundation, meaning it collects and correlates telemetry from multiple security domains (endpoint, network, cloud, identity, email) rather than focusing on a single data source. All managed XDR services are MDR, but not all MDR services use XDR technology. Some MDR providers rely solely on EDR or SIEM, which limits their cross-domain correlation capability. PTG's managed XDR service uses true multi-domain correlation to detect threats that single-domain MDR solutions miss. For more detail, read our MDR vs. XDR comparison guide.
How long does it take to deploy managed XDR?
Most PTG managed XDR deployments reach initial operational capability within two to four weeks. The timeline depends on the complexity of your environment, the number of telemetry sources being integrated, and whether you have existing security tools that need to be connected to the XDR platform. We begin active monitoring as soon as the first telemetry sources are connected, then progressively add domains and tune detection logic over the following weeks. Full operational maturity, with custom detection rules and optimized alert thresholds tuned to your environment, is typically achieved within 60 days.
Do I need to replace my existing security tools to use managed XDR?
No. PTG's managed XDR service is vendor-agnostic, which means we integrate with and operate your existing security tools rather than replacing them. If you already run SentinelOne, CrowdStrike, Microsoft Defender, Palo Alto, or any other supported platform, we connect those tools to the XDR correlation layer and begin monitoring. We will recommend tool changes only when a specific tool has a critical capability gap that affects detection coverage, and any such recommendation is advisory rather than mandatory.
What happens when a threat is detected?
When the XDR platform generates a correlated alert, our SOC analysts investigate it within minutes. For confirmed threats, the response follows your pre-approved incident response playbook. Automated containment actions such as endpoint isolation, account disabling, or IP blocking can execute within seconds for high-severity threats. For threats requiring human judgment, our analysts contact your designated point of contact with a clear summary of the threat, the affected systems, the recommended response actions, and the expected impact. After every significant incident, we deliver a post-incident report with root cause analysis and hardening recommendations.
How does managed XDR support compliance audits?
Managed XDR generates continuous audit evidence that satisfies monitoring and detection requirements across CMMC, HIPAA, PCI DSS, SOC 2, and NIST frameworks. We provide monthly compliance reports showing detection coverage, incident response metrics, and evidence of continuous monitoring mapped to the specific controls your auditors will review. During audit periods, our team works directly with your assessors to provide technical documentation, demonstrate monitoring capabilities, and answer questions about detection and response procedures. The cross-domain audit trail that XDR maintains is among the strongest forms of evidence you can present for security monitoring controls.
What size organization is managed XDR designed for?
PTG's managed XDR service is designed for organizations with 50 to 5,000 endpoints. This includes small and mid-sized businesses, mid-market enterprises, and organizations with distributed environments (multiple offices, remote workforces, multi-cloud deployments). Organizations smaller than 50 endpoints may find that a standard MDR service provides sufficient coverage, while organizations larger than 5,000 endpoints often benefit from a hybrid model where our managed XDR team augments an internal security operations team rather than replacing it entirely.
