The modern threat landscape demands security that never sleeps. Cyberattacks do not respect business hours, holidays, or weekends. They strike at 2 AM on a Saturday, during your busiest quarter, or the week your IT lead is on vacation. For small and medium-sized businesses in the Research Triangle, the challenge is clear: you need enterprise-grade security, but you cannot afford to build and staff a 24/7 security operations center. Managed IT security from Petronella Technology Group solves this challenge, delivering continuous, expert protection through our 39-layer ZeroHack Cyber Safety Stack and AI-powered monitoring by Eve, all for a predictable monthly cost.

Our managed IT security services are not a stripped-down version of what large enterprises deploy. They are the same comprehensive, layered defense methodology, delivered as a managed service by a team with more than two decades of cybersecurity experience. When you partner with Petronella, you gain a dedicated cybersecurity team that monitors your environment 24/7, detects threats in real time, responds immediately to contain incidents, and continuously improves your security posture.

Comprehensive Security Coverage

24/7 Security Operations Center

Our Security Operations Center operates around the clock, monitoring your environment for threats. Our team of security analysts, augmented by our AI agent Eve, analyzes data from your endpoints, network, cloud services, email, and applications to detect malicious activity. When a threat is identified, we investigate immediately and take action to contain and remediate it, often before you are even aware something is happening.

Endpoint Detection and Response

We deploy next-generation endpoint protection across your workstations, servers, and mobile devices. Our EDR solution goes beyond traditional antivirus by continuously monitoring endpoint behavior, detecting sophisticated threats like fileless malware and living-off-the-land attacks, and enabling rapid response to isolate compromised endpoints before threats can spread.

Advanced Email Security

Email is the primary attack vector for phishing, business email compromise, and malware delivery. Our email security service provides multi-layered protection including advanced spam filtering, AI-powered phishing detection, attachment sandboxing, URL rewriting and click-time analysis, and impersonation protection. We also configure and manage DMARC, DKIM, and SPF to prevent email spoofing.

Network Security

We manage your network security infrastructure including next-generation firewalls, intrusion detection and prevention systems, network segmentation, and secure remote access. Our team monitors network traffic for anomalies, manages firewall policies, and ensures your network architecture limits the blast radius of any potential breach.

Vulnerability Management

We conduct continuous vulnerability scanning across your environment, prioritize findings based on exploitability and business impact, and coordinate remediation with your team. Our vulnerability management program ensures that known weaknesses are identified and addressed before attackers can exploit them.

Patch Management

Unpatched systems remain one of the most common attack vectors. Our automated patch management service ensures that operating systems, applications, and firmware receive security updates promptly. We test patches before deployment, schedule updates to minimize disruption, and verify successful installation.

Identity and Access Management

We deploy and manage multi-factor authentication, privileged access management, and access controls across your environment. Stolen credentials are the most common initial access vector for cyberattacks, and strong identity controls are your most effective defense against credential-based attacks.

DNS and Web Security

Our DNS filtering and web security services block access to known malicious domains, prevent command-and-control communications, and protect your users from drive-by downloads and malicious websites. These controls operate at the network level, providing protection regardless of the device or application being used.

Backup and Recovery

We implement and manage encrypted backup solutions that protect your data against ransomware, hardware failure, and other data loss scenarios. Our backup service includes regular integrity testing, secure offsite storage, and documented recovery procedures that have been tested and validated.

Security Awareness Training

Technology controls are most effective when reinforced by educated users. Our training program provides regular security awareness training, simulated phishing campaigns, and ongoing reinforcement to build a security-conscious culture throughout your organization.

The 39-Layer ZeroHack Cyber Safety Stack

Our managed IT security services are built on our proprietary 39-layer ZeroHack Cyber Safety Stack, a defense-in-depth architecture that provides protection at every layer of your environment and at every stage of the attack lifecycle. The stack layers include perimeter defenses, network controls, endpoint protection, application security, data protection, identity management, monitoring, and response capabilities. Each layer is designed to work in concert with the others, so that if any single control is bypassed, other layers detect and contain the threat.

This is not a theoretical framework. The ZeroHack stack has been proven through thousands of real-world engagements and has protected our clients from the same attacks that make headlines at organizations without adequate layered defenses.

AI-Powered Monitoring with Eve

Eve is our proprietary AI monitoring agent that operates at the heart of our managed security services. Eve analyzes telemetry from every layer of the ZeroHack stack, establishing behavioral baselines and detecting anomalies that indicate potential threats. Eve identifies patterns that traditional signature-based tools miss, including slow-moving attacks, lateral movement, unusual data access patterns, and compromised credential usage. When Eve detects a potential threat, she provides context and recommendations that enable our human analysts to investigate and respond quickly.
