Endpoint Detection & Response (EDR): Next-Gen Endpoint Security
Traditional antivirus is no longer enough. Modern attackers use fileless malware, living-off-the-land techniques, and zero-day exploits that evade signature-based detection entirely. Petronella Technology Group, Inc. delivers managed EDR services with AI-powered threat detection, real-time endpoint monitoring, and automated containment — providing continuous protection for every device in your organization, backed by 23+ years of cybersecurity expertise.
Real-Time Monitoring • AI Threat Detection • Automated Containment • Managed EDR • 24/7 SOC Coverage • Forensic Investigation
Q: What is EDR and why does my business need it? Endpoint Detection and Response (EDR) continuously monitors every laptop, desktop, server, and mobile device in your network for signs of malicious activity. Unlike traditional antivirus that only scans for known malware signatures, EDR analyzes process behavior, memory activity, registry changes, and network connections in real time to detect and stop sophisticated attacks including fileless malware, ransomware, and advanced persistent threats. PTG's managed EDR service includes 24/7 SOC monitoring so threats are investigated and contained around the clock. Schedule a free assessment →
Why Traditional Antivirus Falls Short
Endpoints are the primary target for attackers because they are where users interact with data. The threat landscape has evolved far beyond what legacy antivirus was designed to handle.
Managed EDR Service Features
PTG's managed EDR combines advanced detection technology with expert human analysis to protect your endpoints from the full spectrum of modern threats.
Real-Time Endpoint Monitoring
Continuous visibility into every endpoint in your environment: process execution, file system activity, registry modifications, network connections, user behavior, and system configuration changes. Our EDR agents collect deep telemetry without impacting system performance, providing the granular visibility needed to detect threats that operate below the radar of traditional security tools. Every event is correlated with threat intelligence and behavioral baselines to identify malicious activity within seconds of execution. This continuous monitoring covers Windows, macOS, Linux, and server operating systems across your entire device fleet, including remote worker endpoints.
AI-Powered Threat Detection
Machine learning models analyze endpoint behavior to detect threats that signature-based antivirus cannot: fileless malware executing in memory through PowerShell, WMI, or legitimate system tools; zero-day exploits targeting unpatched vulnerabilities; ransomware encryption activity detected by file system behavior analysis; credential dumping from LSASS, SAM, or browser password stores; and lateral movement attempts using stolen credentials or RDP hijacking. Our AI engine reduces false positives by 90% compared to rule-based detection, ensuring your security team focuses on genuine threats rather than chasing phantom alerts. Models are continuously retrained on emerging attack techniques observed across our entire client base.
Automated Containment & Response
When a confirmed threat is detected, automated response actions execute immediately to limit damage: network isolation quarantines the compromised endpoint while preserving forensic evidence, malicious processes are terminated and blocked from restarting, suspicious files are quarantined for analysis, and compromised user credentials are flagged for immediate reset. These automated containment actions execute in seconds rather than the hours or days required for manual response, dramatically reducing the blast radius of attacks. Every automated action is fully auditable and reversible, with your security team maintaining oversight and the ability to customize response playbooks for your environment.
Threat Hunting & Investigation
PTG's security analysts proactively hunt for threats across your endpoints using hypothesis-driven investigation techniques. Our analysts query EDR telemetry for indicators of compromise (IOCs) from threat intelligence feeds, search for behavioral patterns associated with advanced persistent threats (APTs), investigate anomalous activity flagged by AI models, and perform deep-dive forensic analysis when suspicious activity is detected. Threat hunting goes beyond automated detection to identify sophisticated adversaries who have bypassed preventive controls and are actively operating within your environment using legitimate tools and stolen credentials.
24/7 SOC Monitoring & Analysis
Every alert generated by your EDR platform is reviewed by certified security analysts in PTG's AI-powered SOC. Analysts validate threats, investigate context, determine impact, and coordinate response actions around the clock. This eliminates the need to build and staff an internal security operations team while ensuring expert eyes are on your alerts 24 hours a day, 365 days a year. Monthly reporting provides visibility into threat trends, detection metrics, response times, and recommendations for improving your endpoint security posture based on actual attack data from your environment.
Forensic Analysis & Reporting
When incidents occur, PTG's licensed digital forensics examiners conduct thorough endpoint forensic investigations: timeline reconstruction showing exactly how the attacker gained access and what they did, artifact analysis including prefetch files, event logs, browser history, and memory dumps, malware reverse engineering to understand payload capabilities, and comprehensive incident reports suitable for legal proceedings, insurance claims, and regulatory notifications. EDR telemetry provides the forensic breadcrumb trail that makes thorough investigation possible without disrupting business operations by seizing hardware.
EDR vs. Traditional Antivirus: What Is the Difference?
EDR represents a fundamental shift from reactive malware scanning to proactive threat detection and response. Understanding the differences helps you evaluate your endpoint security needs.
| Feature | Traditional Antivirus | PTG Managed EDR |
|---|---|---|
| Detection Method | Signature matching (known threats only) | Behavioral AI + signatures + threat intel |
| Fileless Malware | Cannot detect (no file to scan) | Detects via process and memory behavior |
| Incident Response | Alert only (manual investigation) | Automated containment + SOC investigation |
| Visibility | Scan results only | Full endpoint telemetry and forensics |
| Threat Hunting | Not available | Proactive hunting by certified analysts |

Endpoint Detection & Response Questions, Answered
Does EDR replace our existing antivirus?
Modern EDR platforms include next-generation antivirus (NGAV) capabilities that supersede traditional signature-based antivirus. Most organizations replacing legacy AV with EDR see improved detection rates, reduced false positives, and significantly better protection against advanced threats. PTG evaluates your current antivirus solution and recommends whether to replace it entirely with EDR or layer EDR on top for defense-in-depth. In either case, EDR provides capabilities that antivirus fundamentally cannot: behavioral detection, automated response, threat hunting, and forensic investigation.
Will the EDR agent slow down our computers?
Modern EDR agents are designed for minimal performance impact. The agents PTG deploys typically consume less than 1-2% CPU and 50-100MB of RAM under normal operation. Telemetry collection is optimized to avoid disrupting business applications. During active scans or incident response actions, temporary resource usage may increase slightly but remains well within acceptable thresholds. PTG monitors agent performance across your fleet and tunes configurations if any endpoint experiences issues.
What operating systems does your EDR support?
PTG's managed EDR supports Windows 10/11, Windows Server 2012 R2 and later, macOS 11 (Big Sur) and later, and major Linux distributions including Ubuntu, CentOS, Red Hat Enterprise Linux, Debian, and Amazon Linux. Mobile device monitoring is available through integration with your MDM solution. We ensure consistent protection and visibility across your entire fleet regardless of operating system diversity.
How does managed EDR help with compliance?
EDR addresses endpoint-specific requirements across major compliance frameworks. For CMMC and NIST 800-171, EDR satisfies controls for malware protection (3.14.2), system monitoring (3.14.6-7), and incident response (3.6.1-2). For HIPAA, EDR provides the endpoint monitoring and malware protection required for ePHI-handling devices. For PCI DSS, EDR meets anti-malware and monitoring requirements for systems in the cardholder data environment. PTG provides compliance mapping documentation showing how your EDR deployment satisfies specific framework controls.
What is the difference between EDR and XDR?
EDR focuses specifically on endpoint telemetry — workstations, laptops, and servers. Extended Detection and Response (XDR) expands detection and response across endpoints, network, email, cloud workloads, and identity systems, providing unified visibility and correlated threat detection across your entire environment. PTG offers both managed EDR and managed XDR services. We recommend EDR as a foundational capability and XDR for organizations seeking comprehensive cross-domain threat detection.
