APT Security Management

Managed Network Security Services (MNSS)

Managed Network Security Services (MNSS) is an ongoing service in which a security provider monitors, manages, and protects your network infrastructure against threats like unauthorized access, lateral movement, and data exfiltration. APT Security Management, based in North Charleston, SC, delivers MNSS to businesses across the United States using a prepaid token-based model with no long-term contracts. Whether you run a small office network or a multi-site enterprise environment, APT's team handles the configuration, monitoring, and response so your internal team doesn't have to.

Who Needs Managed Network Security Services

Most businesses have a firewall, but few have someone actively managing it. Firewall rules go stale, configuration drift goes unnoticed, and alerts pile up without anyone trained to act on them. Managed Network Security Services fills that gap.


You likely need MNSS if your business has grown beyond a single office, relies on cloud services or remote workers, or handles regulated data like healthcare records, payment card information, or federal contracts. Any of those situations creates network complexity that increases risk if left unmanaged.


Compliance frameworks including HIPAA, PCI-DSS, NIST CSF, and CMMC require documented network controls, monitoring logs, and evidence of active threat response. APT's MNSS service supports all of those requirements and generates the documentation you need for audits.


Industries that frequently rely on MNSS include healthcare providers, financial services firms, manufacturers with operational technology (OT) environments, and SaaS companies that need to demonstrate security posture to enterprise customers or investors.

Why APT

APT's team holds certifications including OSCP, CISSP, and CEH. These aren't generalist IT professionals: they're security operators who understand how attackers move through networks and configure defenses with that in mind.


APT is vendor-neutral. The team works with solution providers like Fortinet and SonicWall, and recommends the platform that fits your environment and budget, not the one that pays the highest margin.


The token pricing model means you pay for what you actually use. You buy tokens in advance and spend them across any APT service, including MNSS, penetration testing, compliance work, or endpoint security. Tokens are valid for 12 months from purchase. There's no annual contract locking you into a service tier you've outgrown.


APT's three engagement models let you choose how involved you want to be. You can receive scheduled reports by email, access a secure portal with role-specific dashboards, or bring APT into your weekly IT planning meetings. The service adapts to how your team works.

Frequently Asked Questions

What is Managed Network Security Services and how does it work?

Managed Network Security Services (MNSS) is an ongoing, outsourced service that covers the monitoring, management, and protection of your network. APT handles firewall configuration and maintenance, traffic monitoring, intrusion detection, VPN oversight, and threat response on your behalf. Your team receives regular reports and escalation notifications depending on your engagement model.

How is MNSS priced, and what does it cost in tokens?

APT uses a prepaid token system. You buy tokens and spend them on MNSS coverage based on the scope of your environment, including the number of locations, devices, and complexity of your network. There are no annual contracts. Contact us for a token quote specific to your setup.

How long does it take to get started with MNSS?

Most clients complete onboarding within one to two weeks of token purchase. The timeline depends on your current network setup, the firewall platforms in use, and how much baseline documentation already exists. APT handles the integration and configuration as part of the engagement.

What is the difference between Managed Network Security Services and Managed Detection and Response?

Managed Detection and Response (MDR) focuses on detecting and responding to threats across endpoints, email, cloud, and network telemetry at a broad level. MNSS focuses specifically on your network infrastructure: firewalls, traffic flows, segmentation, VPN access, and intrusion detection at the perimeter and internal network level. Many clients use both together for layered coverage.

What technology platforms does APT use for MNSS?

APT works with solution providers like Fortinet and SonicWall for network security and firewall management. We only choose enterprise-grade platforms with strong feature sets for policy management, threat prevention, and logging. APT recommends the platform that fits your environment, not one over the other by default.

What reports and documentation does APT provide?

You receive monthly network security reports covering traffic patterns, detected threats, firewall rule changes, and actions taken. APT also maintains audit-ready logs with retention aligned to your compliance requirements, whether that's HIPAA, PCI-DSS, NIST CSF, or CMMC.

What types of businesses does APT work with for MNSS?

APT works with small businesses, mid-size companies, and enterprises across the United States. MNSS is a strong fit for any organization that handles regulated data, operates across multiple locations, relies on remote access, or needs to demonstrate active network security controls to auditors, insurers, or customers.
