What Are Managed Network Security Services?
Managed network security services are a comprehensive outsourced approach to protecting your organization's network infrastructure from cyber threats. Instead of hiring, training, and retaining an expensive in-house security team, your business partners with a managed security services provider (MSSP) that monitors your firewalls, intrusion detection systems, VPN connections, network segments, and endpoints around the clock.
At Petronella Technology Group, our managed network security services combine advanced threat detection technology with human expertise from a team led by Craig Petronella, MIT-certified cybersecurity professional and expert witness. With over 24 years in the cybersecurity industry and zero client breaches on our managed program, PTG delivers the kind of network protection that most small and mid-sized businesses simply cannot build on their own.
As Craig Petronella details in his book How Hackers Can Crush Your Business, the most common attack vectors, including ransomware, phishing, lateral movement, and data exfiltration, all exploit weaknesses in network security. A single misconfigured firewall rule, an unpatched switch, or an unmonitored network segment can provide the foothold an attacker needs to compromise your entire organization. Managed network security eliminates these blind spots by providing continuous visibility into every corner of your network.
Unlike break-fix IT providers who respond only after a breach occurs, PTG's managed network and security services take a proactive approach. Our Security Operations Center (SOC) analysts monitor your network 24/7/365, correlate events across multiple data sources, and respond to threats in real time, often before your team even knows an incident is underway. This approach aligns with the NIST Cybersecurity Framework pillars of Identify, Protect, Detect, Respond, and Recover.
What Is Included in PTG's Managed Network Security Services
Every engagement is tailored to your environment, but our managed network security platform includes these core capabilities as standard:
24/7 Network Monitoring and Threat Detection
Our SOC monitors all network traffic, endpoints, and connected devices continuously. We use our Managed XDR Suite to correlate events across your environment and detect sophisticated threats that signature-based tools miss, including zero-day exploits, fileless malware, and advanced persistent threats.
Firewall Management and Optimization
We configure, monitor, and maintain your next-generation firewalls with industry best practices. This includes rule auditing, policy optimization, firmware updates, geo-blocking, and real-time alerting on suspicious traffic patterns. Misconfigured firewalls are one of the top five root causes of data breaches, and our team eliminates that risk.
Intrusion Detection and Prevention (IDS/IPS)
Network-based and host-based intrusion detection systems monitor traffic for known attack signatures and anomalous behavior. When a threat is detected, our IPS automatically blocks malicious traffic and our SOC validates the event to prevent false positives from disrupting your operations.
VPN and Remote Access Security
With remote and hybrid workforces now standard, securing VPN connections is critical. We manage your VPN infrastructure with multi-factor authentication, split tunneling policies, and encrypted tunnels that keep remote workers connected without exposing your internal network to unauthorized access.
Network Segmentation and Zero Trust Architecture
We implement network segmentation to isolate sensitive systems, including PCI cardholder environments, HIPAA-regulated ePHI, and CUI for CMMC compliance. Our zero trust approach verifies every user and device before granting access to any network resource, limiting lateral movement in the event of a compromise.
Vulnerability Scanning and Patch Management
Regular automated vulnerability assessments identify weaknesses across your network infrastructure. Our team prioritizes patches based on severity and exploitability, applying critical fixes within 24 hours and maintaining a documented patching cadence that satisfies audit requirements.
DNS and Web Filtering
We deploy DNS-layer security to block malicious domains, phishing sites, and command-and-control servers before they can reach your network. Content filtering policies protect your organization from drive-by downloads and unauthorized SaaS applications that create shadow IT risks.
Compliance-Ready Network Documentation
Every monitoring event, configuration change, and incident response is logged and documented through our proprietary ComplianceArmor platform. This gives you audit-ready evidence for CMMC, HIPAA, SOC 2, PCI DSS, and NIST 800-171 assessments without the manual paperwork burden.
Find Out Where Your Network Is Vulnerable
Our free network security assessment identifies gaps in your defenses before attackers find them. No obligation, no long-term contracts.

We follow a structured five-step methodology that draws on 24+ years of protecting businesses across healthcare, defense, financial services, legal, and manufacturing industries. Here is what happens when you partner with PTG for managed network security:
Network Discovery and Risk Assessment
We begin with a comprehensive audit of your existing network infrastructure: switches, routers, firewalls, wireless access points, VPN concentrators, cloud connections, and every connected device. Our team maps your network topology, identifies all ingress and egress points, and catalogs assets that need protection. This assessment also identifies compliance gaps relevant to your industry, whether that is CMMC for defense contractors, HIPAA for healthcare organizations, or PCI DSS for payment processors.
Security Architecture Design
Based on the assessment findings, we design a layered security architecture tailored to your environment. This includes firewall rule sets, network segmentation strategies, IDS/IPS placement, VPN configurations, DNS filtering policies, and monitoring sensor deployment. We document everything in a System Security Plan (SSP) that maps controls to your compliance requirements through ComplianceArmor.
Deployment and Hardening
Our engineers deploy and configure all network security components, typically completing the rollout within 2-4 weeks depending on environment size. We harden every device to CIS Benchmark standards, implement least-privilege access controls, enable logging on all network devices, and integrate your infrastructure with our SOC monitoring platform. Deployment is done with zero downtime using staged rollouts and rollback procedures.
24/7 Monitoring and Active Threat Response
Once deployed, your network is monitored continuously by our SOC team. We use SIEM (Security Information and Event Management) correlation, behavioral analytics, and threat intelligence feeds to detect and classify events. When a genuine threat is identified, our analysts contain and remediate the issue, often within minutes. You receive real-time notifications and detailed incident reports for every significant event.
Continuous Improvement and Reporting
Network security is not a set-and-forget solution. We conduct quarterly security reviews, monthly vulnerability scans, and annual penetration tests to validate your defenses. You receive monthly executive reports showing threat trends, blocked attacks, compliance status, and recommendations for improving your security posture. Our goal is continuous measurable improvement, which is why we offer a 30-day results promise.

Industries That Rely on PTG for Managed Network Security
Network security requirements vary significantly by industry and regulatory framework. PTG has deep experience securing networks across these verticals:
Healthcare Organizations
Medical practices, hospitals, dental offices, and clinical research organizations must protect electronic Protected Health Information (ePHI) under HIPAA. PTG has completed 340+ healthcare security audits and understands the unique challenges of securing EMR systems, medical devices on the network, and telehealth platforms. As Craig details in How HIPAA Can Crush Your Medical Practice, network security failures in healthcare carry penalties of up to $2.1 million per violation category. Our managed network security includes HIPAA-specific controls, network segmentation for ePHI systems, and automated HIPAA compliance documentation through ComplianceArmor.
Defense Contractors and Government Suppliers
Organizations handling Controlled Unclassified Information (CUI) must meet CMMC 2.0 Level 2 requirements, which include 110 security controls from NIST SP 800-171. Network security is central to CMMC compliance: access control, audit and accountability, system and communications protection, and system and information integrity all require robust network monitoring and management. PTG's Craig Petronella holds the CMMC Registered Practitioner credential and authored the CMMC 2.0 Certification Guide, giving our team direct expertise in meeting these requirements.
Financial Services and Accounting Firms
Banks, credit unions, investment firms, and accounting practices face regulatory requirements from the FTC Safeguards Rule, SOX, PCI DSS, and state-level data protection laws. PTG secures financial networks with encryption, network segmentation for cardholder data environments, and real-time monitoring for unauthorized data transfers.
Law Firms
Attorneys handle confidential client data protected by attorney-client privilege and increasingly by state bar cybersecurity guidelines. PTG's managed network security for law firms includes encrypted communications, secure document management networks, and privileged access monitoring. Craig serves as a cybersecurity expert witness in legal cases, giving our team a unique perspective on the intersection of network security and legal liability.
Manufacturing and Engineering
Operational technology (OT) networks in manufacturing facilities and engineering firms require specialized security approaches. PTG implements IT/OT network segmentation, monitors industrial control systems for anomalies, and secures the convergence points where business networks connect to production systems.
Technology Companies and SaaS Providers

Network Security Threats PTG Protects Against
The threat landscape facing business networks continues to evolve. Here are the most common and dangerous attack types that our managed network security services detect and block:
Ransomware and Malware
Ransomware attacks cost businesses an average of $4.88 million per incident according to the 2024 IBM Cost of a Data Breach Report. PTG's network monitoring detects ransomware indicators, including unusual file encryption activity, lateral movement attempts, and communication with known command-and-control servers, before encryption can spread across your network. Our backup and disaster recovery services provide a safety net with immutable backups that cannot be encrypted by attackers.
Phishing and Social Engineering
Over 90% of successful cyberattacks begin with a phishing email. Our network security includes DNS-layer filtering that blocks access to phishing sites even if a user clicks a malicious link, email security gateways that quarantine suspicious messages, and security awareness training with simulated phishing campaigns that reduce click rates by an average of 75% within 90 days.
Insider Threats and Unauthorized Access
Not all threats come from outside your network. Disgruntled employees, compromised credentials, and excessive access privileges can all lead to data theft or sabotage. PTG implements user behavior analytics (UBA), privileged access monitoring, and network access control (NAC) to detect and prevent insider threats before data leaves your network.
Distributed Denial of Service (DDoS)
DDoS attacks can overwhelm your network infrastructure and take your business offline. PTG deploys traffic analysis and rate limiting at the network edge, combined with upstream filtering through our security partnerships, to absorb and mitigate volumetric and application-layer DDoS attacks while keeping your legitimate traffic flowing.
Advanced Persistent Threats (APTs)
State-sponsored and organized criminal groups use sophisticated techniques to establish long-term footholds in target networks. PTG's threat hunting team actively searches for indicators of compromise, dormant implants, and covert communication channels that evade automated detection. Our network forensics capabilities allow us to trace attacker activity across your infrastructure and close every access path.
Managed Network Security Cost and ROI
Understanding the financial case for managed network security helps justify the investment to your leadership team. Here is a realistic breakdown:
What Managed Network Security Services Cost
PTG's managed network security services typically range from $3,000 to $8,000 per month depending on the size of your network, number of locations, compliance requirements, and service tier. This includes all monitoring, management, patching, incident response, and compliance documentation. There are no hidden fees, and pricing scales predictably as your network grows.
The Cost of Building In-House
To match PTG's managed network security capabilities internally, you would need at minimum: a CISO or security manager ($120,000-$180,000/year), 4-5 SOC analysts for 24/7 coverage ($280,000-$400,000/year), SIEM and monitoring tools ($50,000-$150,000/year), and firewall and IDS/IPS hardware ($20,000-$80,000 upfront). The total comes to $470,000-$810,000 in year one and $300,000-$600,000 annually thereafter, which is 3-8 times more expensive than outsourcing to PTG.
The Cost of a Network Breach
According to IBM's 2024 Cost of a Data Breach Report, the average data breach costs $4.88 million globally. For healthcare organizations, the average is $9.77 million. These figures include direct costs like incident response and notification, plus indirect costs like lost business, reputational damage, and regulatory fines. A single breach can erase years of profit. For businesses subject to HIPAA, CMMC, or PCI DSS, regulatory penalties add another layer of financial exposure.
ROI of Managed Network Security
At $5,000 per month ($60,000/year), PTG's managed network security costs roughly 1.2% of the average breach cost. If our monitoring and prevention stops even one significant incident over a multi-year engagement, the return on investment exceeds 8,000%. Beyond breach prevention, businesses that can demonstrate robust network security win larger contracts, meet compliance requirements faster, and reduce cyber insurance premiums by 15-30%.

Schedule Free Assessment Call 919-348-4912Frequently Asked Questions About Managed Network Security Services
What is the difference between managed network security and managed IT services?
Managed IT services cover day-to-day technology operations like helpdesk support, software updates, and user management. Managed network security is a specialized subset focused specifically on protecting your network infrastructure from cyber threats through 24/7 monitoring, firewall management, intrusion detection, and incident response. At PTG, we offer both as integrated services, which eliminates gaps between your IT operations and security teams. Many of our clients start with managed IT and add network security as their compliance requirements grow.
How quickly can PTG deploy managed network security for my business?
Most deployments are completed within 2-4 weeks from contract signing. The first week focuses on network discovery and assessment. Weeks two through four cover architecture design, hardware deployment, sensor installation, and integration with our SOC monitoring platform. Critical monitoring begins within the first week, with full coverage typically active by day 14. Complex multi-site deployments may require additional time, which we scope during the initial assessment.
Do I need to replace my existing firewalls and network equipment?
Not necessarily. PTG's managed network security services work with most enterprise-grade network equipment from vendors like Fortinet, Palo Alto, Cisco, SonicWall, and Meraki. During our assessment, we evaluate your current hardware and recommend replacements only when equipment has reached end-of-life, lacks critical security features, or cannot support the monitoring capabilities your security posture requires. We never recommend unnecessary hardware purchases.
How does PTG's managed network security help with compliance?
Our managed network security maps directly to compliance framework requirements. For CMMC, we address access control (AC), audit and accountability (AU), system and communications protection (SC), and system and information integrity (SI) families. For HIPAA, we implement the technical safeguards required by the Security Rule. For PCI DSS, we manage network segmentation and monitoring for cardholder data environments. Our ComplianceArmor platform automatically documents all security controls and generates evidence packages for your auditors.
What happens when PTG detects a threat on my network?
Our SOC follows a tiered response process. Automated systems immediately block known malicious traffic and quarantine affected endpoints. SOC analysts then validate the threat, assess scope and impact, and execute containment procedures. You receive real-time notifications via your preferred channel (email, phone, Slack, or Teams). For confirmed incidents, our incident response team, which includes Craig Petronella as NC Licensed Digital Forensics Examiner, leads the investigation, containment, eradication, and recovery process. Post-incident, we provide a detailed report and implement lessons learned to prevent recurrence.
Can PTG manage network security for multiple office locations?
Yes. PTG manages multi-site network security for organizations with anywhere from 2 to 50+ locations across the United States. Our centralized SOC monitors all locations through a unified platform, while site-specific policies accommodate the unique requirements of each facility. We support hub-and-spoke architectures, SD-WAN deployments, cloud-connected branches, and hybrid environments where some locations use on-premises infrastructure while others rely on cloud services.
How much do managed network security services cost?
PTG's managed network security typically costs between $3,000 and $8,000 per month, depending on network size, number of locations, compliance requirements, and service tier. This is 40-60% less expensive than building equivalent capabilities in-house, which requires a minimum of $300,000-$600,000 annually in staffing and tools. We provide transparent, predictable pricing with no hidden fees, no long-term contracts, and a 30-day results promise.
