Network security for a small business costs $150 to $600 a month on average in 2026, with basic firewall-and-antivirus coverage starting around $99 and fully monitored, layered security stacks running $2,000 or more for offices past 25 employees. That headline number almost never includes one-time setup and configuration fees, which typically add another $500 to $1,500 before the first monthly invoice arrives.

- Employee count, compliance rules, and monitoring level drive most of the cost swing.
- Network security scoped for NC small businesses starts with a free diagnostic before pricing.
Why this matters
A single ransomware incident or a stolen laptop can shut a small office down for days, and the recovery bill from cleanup, downtime, and client notification almost always dwarfs a full year of managed network security. Cyber insurance carriers in North Carolina increasingly require proof of a managed firewall, endpoint protection, and backups before they'll quote a policy in 2026. Skipping network security doesn't remove the cost, it just shifts it from a predictable monthly line item to an unpredictable emergency invoice.
For hands-on network security support in North Carolina, TechConnect LLC scopes a package around employee count and risk exposure rather than a flat rate for every office, starting with a free diagnostic to see what's already exposed.
How much does network security cost for a small business?
Network security pricing for a small business in 2026 splits into three tiers based on how much monitoring and threat response is bundled in, not just which tools get installed. The table below breaks down what each tier actually covers.
| Tier | Monthly cost | What's included | Best for |
|---|---|---|---|
| Basic | $99–$250 | Firewall management, antivirus/endpoint protection, patch management | Solo offices and teams under 10 employees |
| Layered | $250–$600 | Firewall, endpoint detection and response, email filtering, business VPN, employee security training | 10–25 employees, hybrid or remote staff |
| Enterprise-grade | $600–$2,000+ | 24/7 monitoring, SIEM alerting, backup and disaster-recovery integration, compliance reporting | 25–50 employees, regulated industries |
Basic network security: $99 to $250 a month
A basic package covers a managed firewall, endpoint antivirus, and regular patching, which is the floor for any business handling customer payment data or email. It won't catch a phishing email the way a layered stack would, and it skips 24/7 alerting entirely. Buy if you're a solo operator or under 10 employees with low compliance exposure; skip it if you handle card payments or patient records daily.
Layered security stack: $250 to $600 a month
This tier adds endpoint detection and response, email filtering, and a business VPN on top of the basic package. It's the level most offices researching network security services for small businesses in Charlotte settle on once they cross 10 employees or add remote staff. It costs more than basic coverage but catches threats antivirus alone misses. Buy for any office with remote or hybrid workers; hold at basic if your team is fully in-office and under 10 people.
Enterprise-grade small business security: $600 to $2,000+ a month
Enterprise-grade coverage adds around-the-clock monitoring, SIEM alerting, and backup/disaster-recovery integration built into the security stack instead of sold separately. It's the right tier for accounting firms, medical practices, and law offices managing compliance audits, but it's overkill for a five-person retail shop. Buy if you're in a regulated industry or handle sensitive client data at scale; wait if you're under 15 employees with no compliance mandate.
Why network security costs vary
- Employee and device count — more endpoints means more licenses and more activity to monitor.
- Compliance requirements — HIPAA, PCI-DSS, and state breach-notification rules add reporting and audit work.
- Remote and hybrid work — VPNs, home-office firewalls, and secured personal devices push the layered tier higher.
- Monitoring level — business-hours support costs less than 24/7 SIEM alerting.
- Age of existing hardware — outdated routers and switches often need replacing before a firewall upgrade works right.
- Number of office locations — every additional site adds its own firewall and monitoring line item.

Is network security worth it for a small business in 2026?
Yes — $150 to $600 a month for network security costs far less than the days of downtime and client-notification work that follow a breach. Insurance underwriters are also tightening requirements in 2026, and many won't issue a policy without proof of a managed firewall and endpoint protection.
Does managed IT support include network security?
Managed IT support sometimes bundles basic network security into the flat monthly fee, but layered or enterprise-grade protection is often billed as an add-on. Check the scope of any managed IT contract before assuming firewall management, endpoint detection, and 24/7 monitoring are already covered.
How much does managed IT support cost per month for a small office?
Managed IT support costs vary by scope and headcount, and network security is usually one line item inside that bill rather than the whole quote. See the full monthly cost breakdown in the managed IT support cost guide before budgeting for security separately.
FAQ
How much does network security cost for a small business in 2026?
Network security costs $150 to $600 a month on average for a small business in 2026, ranging from $99 for basic firewall and antivirus coverage up to $2,000 or more for a fully monitored stack. Setup fees of $500 to $1,500 usually apply on top of the monthly rate.
What's included in basic network security for a small business?
Basic network security includes a managed firewall, endpoint antivirus, and regular patch management. It's the minimum floor for any business handling customer payment data or email.
Is endpoint protection different from network security?
Endpoint protection covers individual devices like laptops and desktops, while network security covers the firewall, VPN, and traffic monitoring around the whole office. Most small business security packages bundle both.
How much does antivirus alone cost compared to full network security?
Antivirus alone typically costs less than the $99 to $250 basic network security tier, since it's only one component of that package. Firewall management and patching are billed separately or bundled in.
Do small businesses need 24/7 network monitoring?
Not every small business needs 24/7 monitoring — it's mainly justified for regulated industries like healthcare, legal, and finance. Businesses under 15 employees with no compliance mandate usually do fine with business-hours monitoring at the layered tier.
How much do network security setup fees cost?
Setup and configuration fees for network security typically run $500 to $1,500 in 2026, covering firewall configuration and an initial network audit. This is a one-time cost separate from the monthly rate.
Can TechConnect LLC handle network security for a small business in North Carolina?
Yes, TechConnect LLC scopes network security packages for small businesses across North Carolina based on employee count and risk exposure, starting with a free diagnostic.
One last thing
Most small businesses cut the wrong corner — they skip the $500 to $1,500 setup fee, configure the firewall once themselves, and never revisit the default settings. A misconfigured firewall left untouched for months costs more to clean up than the setup fee would have in the first place. Pay for the configuration work upfront in 2026; that's the line item that actually prevents the emergency invoice.
