Where Almost Every Attack Tries to Get In

Every device, application, and remote connection is a potential way in. When a network is left loosely defended, a single weak point, an open port, an unmonitored firewall, a stale VPN, is all an attacker needs. Network Security Services in Minnesota build a strong, monitored perimeter and watch it around the clock, so threats are stopped at the edge instead of slipping inside your systems. Delivered as part of the managed IT and cybersecurity support of RYMARK IT Navigation, it anchors our broader cybersecurity services.

Guard Every Entry: We secure the firewalls, connections, and access points attackers probe first, closing the easy ways in.
Watch It Always: Continuous monitoring means suspicious activity is caught early, not discovered after the damage.
Contain Threats Fast: If something does get through, we isolate and stop it before it spreads across your network.
Keep Workflowing: Strong security should protect uptime, not get in its way, so your team keeps moving.

The Layers That Keep Your Network Safe

Real network security is layered. It controls who gets in, watches what happens inside, and responds fast when something looks wrong. Here is what we put in place for businesses in Minnesota.

Managed Firewall Protection

Your firewall is the front door, and a misconfigured one is worse than none. We deploy and manage next-generation firewalls that block unauthorized access and inspect traffic for threats.

Next-generation firewalls configured and maintained.
Traffic inspected for malicious activity.
Rules kept current as your needs change.

Network Monitoring

You cannot defend what you cannot see. Our 24/7 SOC watches your network continuously, flagging unusual activity before it becomes an incident.

Continuous monitoring of network traffic and devices.
Early alerts on unusual or suspicious activity.
Visibility across your entire environment.

Wireless Security

An open or weak wireless network is an invitation. We lock down your Wi-Fi with strong encryption, segmentation, and access controls.

Secure, encrypted wireless networks.
Separate access for guests and staff.
Controls that keep unauthorized devices off.

Threat Detection and Response

Detection means little without action. Serious network threats feed into our managed detection and response, where our team investigates and acts.

Expert review of serious network threats.
Fast containment of active attacks.
A clear path from alert to resolution.

Secure Remote Access

Your team works from everywhere, and each connection is a risk if left unprotected. We secure remote access with encrypted connections and multi-factor authentication.

Encrypted VPN and secure remote connections.
Multi-factor authentication on network access.
Safe access for remote and hybrid teams.

Network Segmentation

When everything is connected, one breach can reach everything. We segment your network and tighten cloud security so a problem in one area cannot spread to the rest.

Segmented networks that contain threats.
Sensitive systems isolated from general access.
Limited reach for any single compromise.

Intrusion Detection and Prevention

Attackers test defenses constantly, looking for a way through. We detect and block intrusion attempts in real time, stopping threats before they reach your systems.

Real-time detection of intrusion attempts.
Automatic blocking of known attack patterns.
Fewer openings for attackers to exploit.

Vulnerability and Penetration Testing

You cannot fix weaknesses you have not found. Alongside network security, we offer dedicated penetration testing to probe your defenses the way an attacker would.

Testing that reveals real network weaknesses.
Prioritized findings you can act on.
A clear path to closing the gaps.

Attackers Only Need to Find One Gap

Attackers do not need to beat every defense. They need one, a forgotten firewall rule, an unpatched device, a shared password on an exposed connection. Once inside a flat, unmonitored network, they can move freely toward the data that matters.

That is why network security cannot be a one-time setup. Threats evolve, configurations drift, and new devices connect every week. Our security breach response team is ready if an attack ever gets through, but strong, monitored network defenses are what keep that day from coming. Industry research puts the average small-business breach well into six figures, and many begin with a single exposed point on the network.

Why Twin Cities Teams Trust Us With Their Network

Network security is only as good as the monitoring and response behind it. RYMARK IT Navigation was founded in 1997 by two managing partners who spent 25 years running businesses of their own, and more than 100 Twin Cities organizations, a 4.9-star rating, and a CBS Minnesota feature stand behind our work. You get a monitored, managed network backed by people who respond.

Layered defense: protection across the perimeter, interior, and every connection, so no single failure exposes everything.
Real monitoring: round-the-clock oversight, so threats that surface at night are caught, not left until morning.
Fast response: serious threats investigated and contained quickly by real people, not just flagged.
Local support: a responsive Twin Cities team and help desk support that already knows your setup.
Business focus: defense tuned to how your team works, protecting uptime instead of blocking it.
Full coverage: network security coordinated with your email security, endpoint, and access defenses.

What Tighter Network Security Actually Changes

Securing your network does more than block attacks. It changes how safely and steadily your business in Minnesota runs every day.

Fewer breaches: a monitored, layered network defends the entry points attackers rely on most.
Less downtime: contained threats keep one problem from taking the whole team offline.
Protected data: sensitive systems stay shielded, and customer and business data stays private.
Insurance confidence: documented firewalls and monitoring support your applications and renewals.
Secure growth: defenses scale with you as you add users, sites, and devices.
Peace of mind: a watched, defended network lets you focus on the business, not the threats.

Network Security Questions We Hear a Lot

What is network security?

Network security is the set of defenses that protect your business network from unauthorized access, malware, and attacks. It includes firewalls, monitoring, intrusion prevention, segmentation, and secure remote access, working together to keep intruders out and your data protected.

What is the difference between network security and cybersecurity?

Cybersecurity is the broad practice of protecting all of your systems and data, while network security is the part focused specifically on your network, its connections, firewalls, and traffic. Network security is one essential layer within a complete cybersecurity strategy.

What does managed network security include?

It typically includes managed firewalls, continuous monitoring, intrusion detection and prevention, network segmentation, secure remote access, and threat response. We tailor the mix to your business so protection matches how your network is actually used.

How does network security protect against ransomware?

Strong network defenses block the intrusion attempts and lateral movement ransomware relies on, and segmentation keeps an infection from spreading. Combined with monitoring and fast response, that greatly reduces both the chance and the impact of an attack.

How is network security different from penetration testing?

Network security is the ongoing protection of your network, while penetration testing is a point-in-time exercise that probes those defenses to find weaknesses. The two work together, and we offer dedicated penetration testing alongside our managed network security.

Does network security help with cyber insurance?

Yes. Insurers increasingly expect managed firewalls, monitoring, and secure remote access, and documented network security supports both your application and your renewals.

How do we get started?

It begins with a network security review that shows where your defenses are weak. From there, we design and put in place a layered defense, then monitor and maintain it going forward.
