Network Security

Your firewall is only as good as the last time somebody looked at it. We design, deploy and actively manage the perimeter and the traffic moving inside it.

A perimeter that is maintained

Firmware, rules and threat feeds stay current. Most of the firewalls we inherit have not been touched since the day they were installed.

Damage that stays contained

Segmentation means a compromised laptop cannot reach your servers, your cameras or your point of sale. Breaches become incidents instead of disasters.

Remote access without the hole

Modern VPN and zero trust access replaces the exposed remote desktop ports that ransomware crews scan for continuously.

The perimeter is not a box you install once

Nearly every firewall we inherit tells the same story. It was specified correctly, installed competently, and then never touched again. Firmware three years behind. A dozen rules whose purpose nobody can explain. Intrusion prevention licensed but never enabled. Logging that goes nowhere.

None of that is negligence exactly. It is what happens when security hardware is treated as a purchase rather than a service. Threats change weekly. A device that is not being maintained is protecting you against last year.

Network security at Fiber1Solutions means the equipment and the ongoing attention to keep it effective.

Design: build zones, not a shell

The old model put a hard shell around a soft interior. Once something got inside, it could reach everything. That model fails badly against modern ransomware, which is designed specifically to move laterally the moment it lands.

We design networks in zones. Staff workstations, servers, guest wireless, IP cameras, point of sale, building automation and printers each live in their own segment with explicit rules about what can talk to what. A compromised laptop in the sales VLAN simply cannot reach the accounting server, because the path does not exist.

This is the single highest value architectural decision most businesses can make, and it is dramatically cheaper to do during a cabling project or an office move than to retrofit later.

Deploy: hardware sized to the actual load

Firewall sizing is where a lot of deployments go wrong. Throughput numbers on a datasheet assume inspection features are off. Turn on intrusion prevention, TLS inspection and application control and real throughput can fall by half or more.

We size on your actual circuit speed, user count and the features you intend to run, with headroom for growth. Then we configure properly: intrusion prevention enabled and tuned, geo blocking where it makes sense, application control aligned to your policies, logging forwarded somewhere that retains it, and administrative access locked down with multi factor authentication.

Manage: the part that gets skipped

An active management agreement covers the ongoing work that keeps the investment worth something.

Firmware updates get applied on a scheduled maintenance window after we have checked release notes for known issues. Threat intelligence feeds stay licensed and current. Rule sets get reviewed quarterly and documented, with stale exceptions removed. Certificates get renewed before they expire rather than at 2am when a service goes down.

You get reporting that shows what was blocked, where your bandwidth went, which applications your staff actually use and whether anything anomalous showed up in the logs.

Remote access done properly

Exposed remote desktop remains one of the most reliable ways ransomware crews get into a business. It is scanned for constantly and credential stuffed automatically.

We replace it. For most clients that means a managed VPN with multi factor authentication and device posture checks, so only a known, healthy machine with a verified user gets a tunnel. For larger or more distributed environments we deploy zero trust network access, which grants a user access to a specific application rather than to the network as a whole, which sharply limits what a compromised account can reach.

Wireless that is actually a security boundary

Guest Wi-Fi sharing a network with your servers is more common than it should be. We deploy managed wireless with proper separation: a guest network that reaches the internet and nothing else, a corporate network authenticated against your directory, and where needed a separate network for devices such as scanners and IoT hardware that cannot support modern authentication.

Coverage matters too. We survey the space rather than guessing at access point placement, because a wireless network that drops calls will get worked around by staff, and the workarounds are usually the security problem.

Where this fits

Network security is one layer. It pairs with cybersecurity for the endpoint and identity side, and with backup and disaster recovery for the day something gets through anyway. Clients on managed IT get all three coordinated under one agreement, which is generally both cheaper and more coherent than buying them separately.

FAQ

Network Security questions

Still stuck? Send us the question and a real engineer will answer it.

Our firewall came from the internet provider. Is that a problem?

Usually yes. Carrier supplied gateways are built to deliver a circuit, not to defend a business. They typically lack intrusion prevention, application control, meaningful logging and any kind of managed update cycle. They are fine as a modem. They are not a security control.

What is network segmentation and do we need it?

Segmentation splits your network into zones so devices can only reach what they legitimately need. Cameras, guest Wi-Fi, point of sale terminals and building systems all get separated from your servers and staff workstations. If a device is compromised, segmentation is what stops it from spreading. Almost every business benefits, and for PCI DSS it is effectively required.

Is a VPN still the right answer for remote work?

A properly configured VPN with multi factor authentication is still perfectly sound for most businesses. What is not sound is exposing remote desktop directly to the internet, which remains one of the most common ransomware entry points we see. For larger or more distributed teams, zero trust network access is often a better fit because it grants access per application rather than dropping users onto the whole network.

How often should firewall rules be reviewed?

At least annually, and after any significant change. Rule sets accumulate. Somebody opens a port for a vendor project in 2021, the project ends, the rule stays. We review the full policy on a schedule and document what each remaining rule is for.

Do you work with our existing hardware?

Where it is current and capable, yes. We are certified on Sophos and Ubiquiti and we work regularly with Fortinet, Meraki and SonicWall. If your hardware is past end of support we will say so, because unsupported firewalls stop receiving the threat intelligence that makes them useful.
