What Goes Wrong at the Network Edge?

A firewall protects a business only for as long as someone maintains it. Many network security problems stem from configuration drift, outdated equipment, and neglected maintenance rather than the absence of a firewall.

Rules Pile Up and Nobody Prunes Them

Firewall rule sets grow with every project and rarely shrink, and one broad rule left in place from an old project can quietly undo the rest of the policy.

Devices Reach End of Support

Hardware that no longer receives firmware updates keeps passing traffic while the known flaws in it stay unpatched.

Protection Subscriptions Lapse

Intrusion prevention, content filtering, and gateway inspection depend on active licensing, so an expired subscription can leave a device forwarding traffic with its inspection switched off.

Flat Networks Let Intruders Roam

Flat networks can make it easier for an attacker or malware to move between systems once access is gained.

What Does Managed Network Security Do for Your Business?

ITS treats your network as something to be designed, maintained, and watched, rather than a box to be installed and forgotten.

Keep Firewall Policy Under Control

Rule reviews, documented changes, and firmware maintenance keep policy matching how the business actually operates.

Contain What Gets In

Segmentation separates servers, user devices, guests, and operational equipment to help limit how far an incident can spread.

Secure Remote and Vendor Access

Remote staff, branch sites, and vendors connect through controlled, authenticated access paths designed to reduce unnecessary exposure.

See What Crosses the Perimeter

Monitoring of supported devices surfaces outages, configuration drift, and traffic worth investigating.

What Does ITS Network Security Include?

Depending on your ITS package and supported hardware, network security coverage can include the following capabilities.

Firewall Design and Deployment

Sizing, configuration, and installation of business firewalls, with rule sets built around how your business actually uses the network.

Firewall Maintenance and Lifecycle

Firmware updates, subscription and license tracking, configuration backups, and end-of-support planning for supported devices.

Rule and Policy Review

Periodic review of firewall rules to retire what is no longer needed and tighten anything broader than it needs to be.

Network Segmentation

Separation of servers, user devices, guest access, and operational technology, so movement between them is deliberate rather than assumed.

Secure Remote Access

Managed remote access with authentication requirements for staff, branch sites, and vendors, replacing exposed services and open inbound ports.

Network and Wireless Monitoring

Monitoring and management of supported firewalls, switches, and wireless infrastructure for availability, configuration change, and anomalies, with escalation through ITS support.

How Does ITS Manage Network Security?

Establish what is actually there, correct what is exposed, then keep it maintained rather than rediscovering it later.

  1. 01Assess the Current Network

    ITS reviews and documents the supported network infrastructure in scope, including firewalls, switching, wireless, remote access, and segmentation.

  2. 02Design and Implement

    ITS proposes and implements changes in priority order, starting with lapsed protections and overly broad rules, then moving to segmentation and remote access improvements.

  3. 03Maintain and Monitor

    Firmware, rules, licensing, and configuration backups are maintained, supported devices are monitored, and changes are documented as the network evolves.

How Much Does Managed Network Security Cost?

Network security is delivered as part of ITS cybersecurity and managed IT coverage rather than as a standalone product. Cybersecurity and managed IT services typically start at $125 per user per month, and network hardware is quoted separately from service coverage.

Your final cost depends on these factors together. Schedule a meeting below to get a personalized cost estimate for your environment.

Schedule a Meeting

What shapes your final cost

  • Number of Users and Sites

    Pricing considers user count, number of locations, and the equipment and management scope required at each site.

  • Devices Under Management

    How many firewalls, switches, and wireless access points come under ITS management.

  • Hardware and Licensing Position

    Whether your existing equipment can be brought under management as it stands, and which protection subscriptions are current.

  • Selected Package

    Which ITS package you choose, since coverage differs between packages.

How ITS Works With Your Team on the Network

Two working habits that keep a managed network from drifting back into guesswork.

Changes Are Documented

Firewall and network changes are recorded along with the reason behind them, so the current configuration can be explained rather than reverse engineered later.

Lifecycle Is Tracked, Not Discovered

Firmware levels, subscription renewals, and end-of-support dates for supported devices are tracked, so replacement is planned rather than urgent.

See What Clients Say About ITS Cybersecurity Services

Hear from organizations that partner with ITS to protect their operations and build a stronger security posture.

I think... to not adopt some form of advanced security these days would be incredibly foolish. The biggest benefit ITS provides is the weight off my shoulders knowing that they're involved, and we've prepared ourselves as best as we could for any cyberthreats. That component is the most important to us.

JP HalversonVice President, McQuarrie Associates

We had an issue with a ransomware problem, and our previous IT partner could not resolve it. It brought us to a standstill... so we reached out to ITS and they helped us with the issue.

Mark BreauningerDirector of Operations, The Synthetic Grass Store

ITS identified an MFA hole in a large-scale EHR system that had never been caught before. Had it not been for them, we would've gone live and unknowingly increased our risk. Their insight not only protected us, [but it also] helped four other facilities that implemented the same system after us.

Network Security: Frequently Asked Questions

What does managed network security include?

It covers the design, configuration, maintenance, and monitoring of the equipment and policy that control traffic into, out of, and across your network: firewalls, switching and wireless, segmentation, and remote access. Your exact coverage depends on your ITS package and supported hardware.

Is a firewall enough on its own?

No. A firewall is only one layer of defense. It cannot by itself address every risk, including stolen credentials, malicious files, endpoint compromise, or lateral movement.

What is network segmentation, and do we need it?

Segmentation divides a network into zones so devices in one zone cannot freely reach another, which limits how far an intruder or a piece of malware can travel. It matters most where sensitive systems, payment environments, or building and operational equipment share a network with everyday workstations.

How often should firewall rules be reviewed?

Rules should be reviewed on a defined schedule and whenever the business changes: a new application, a new site, staff departures, or the end of a vendor relationship. Several regulatory frameworks require periodic review of firewall configuration, and PCI DSS from the PCI Security Standards Council is explicit about it for cardholder data environments.

What happens when a firewall reaches end of support?

It keeps passing traffic, but it stops receiving firmware and security updates and its inspection subscriptions may no longer renew. ITS tracks end-of-support dates for supported devices so replacement can be planned ahead of that point rather than after an incident.

Can ITS manage the firewall we already have?

Often yes. ITS reviews the make, model, firmware level, licensing status, and configuration of your existing equipment, then tells you whether it can be brought under management as it stands or should be replaced. Supported platforms are confirmed during onboarding.

Is Anyone Actually Maintaining Your Network?

Meet with an ITS cybersecurity expert to review your firewall configuration, segmentation, and remote access paths, and to see which network changes would reduce the most risk.
