What Managed Network Security Includes

End-to-end network protection managed by our security operations center, from perimeter defense to internal segmentation.

Firewall Management

We deploy, configure, monitor, and maintain next-generation firewalls. Rule optimization, firmware updates, policy audits, and real-time threat blocking are included. No more set-it-and-forget-it firewalls with default rules.

Intrusion Detection and Prevention

Network-based IDS/IPS monitors all traffic for malicious patterns, exploit attempts, and anomalous behavior. Our SOC analysts investigate every alert and take immediate action on confirmed threats.

24/7 SOC Monitoring

Our security operations center monitors your network around the clock. We analyze NetFlow data, firewall logs, DNS queries, and packet captures to detect threats that endpoint tools miss.

Network Segmentation

We design and implement network segmentation to contain breaches and meet compliance requirements. VLANs, micro-segmentation, and zero-trust network architecture prevent lateral movement.

VPN and Remote Access

Secure remote access for your workforce with enterprise VPN, multi-factor authentication, and conditional access policies. We ensure remote workers are as secure as on-site employees.

Vulnerability Management

Regular network vulnerability scans identify weaknesses before attackers do. We prioritize findings by risk, coordinate patching with your team, and verify remediation.

Why It Matters

The Risk of Unmanaged Network Security

Most small businesses have firewalls they set up years ago and never touch again. That is not security. That is a false sense of security.

Your Firewall Is Not Enough

A firewall is a critical first line of defense, but it is only effective when properly configured, regularly updated, and actively monitored. Research shows that 99% of firewall breaches are caused by misconfigurations, not technology failures. Default rules, unused open ports, overly permissive policies, and outdated firmware create gaps that attackers exploit daily.

Managed network security means someone is watching your firewall 24/7, tuning rules based on threat intelligence, and responding immediately when something suspicious passes through.

Threats Your Endpoints Cannot See

Endpoint detection catches threats on individual devices, but many attacks operate at the network level. DNS tunneling exfiltrates data through DNS queries. Command-and-control traffic hides in legitimate HTTPS connections. Lateral movement between systems happens entirely on the wire, invisible to endpoint agents on each individual machine.

Network-level monitoring catches these threats by analyzing traffic patterns, identifying anomalous connections, and correlating activity across your entire infrastructure. Combined with our MDR service, you get visibility across every layer of your environment.

Compliance Requires Network Controls

Every major compliance framework requires specific network security controls. CMMC requires network monitoring, access control, and segmentation. HIPAA mandates network safeguards for protected health information. PCI DSS requires firewall rules review, network segmentation, and intrusion detection.

Our managed network security service maps directly to these requirements with pre-built compliance reporting. During audits, we provide the documentation, evidence, and technical explanations that auditors need.

FAQ

Frequently Asked Questions

What firewalls do you support?
We manage all major enterprise firewall platforms including Palo Alto, Fortinet, SonicWall, Cisco, and Sophos. If you already have firewalls deployed, we can take over management. If you need new hardware, we will recommend the right platform for your environment and budget.
How is this different from just buying a firewall?
Buying a firewall gives you hardware. Managed network security gives you a team that configures, monitors, and responds to threats 24/7. The firewall is one component of a complete network security strategy that includes IDS/IPS, segmentation, vulnerability management, and active monitoring. Without management, a firewall is just a box on your rack.
Can you manage our network security remotely?
Yes. All network monitoring and most configuration changes are performed remotely through secure management channels. For on-site hardware deployments or complex network redesigns in the Raleigh-Durham area, our team can be on-site as needed.
How does this integrate with endpoint security?
Network security and endpoint security are complementary layers. Our managed network security integrates with our MDR service to provide correlated detection across both layers. When our network sensors detect suspicious traffic, we can cross-reference with endpoint telemetry for faster, more accurate threat identification.
What compliance frameworks does this support?
Our managed network security supports CMMC, HIPAA, SOC 2, PCI DSS, NIST 800-171, and NIST CSF. We provide pre-built compliance reports that map your network security controls to specific framework requirements. Our vCISO team can provide additional compliance advisory support.
