Small Business Cybersecurity Cost: What to Budget in 2026

Q: How much should a small business spend on cybersecurity per month?

There is no single right number, but most small businesses end up paying a per-user monthly fee for a managed security stack that includes endpoint protection, email filtering, MFA and monitoring, plus a few annual items such as training and an assessment. The right amount depends on headcount, industry regulation and what you already have in place, which is why an assessment before buying is worthwhile.

Q: Is cybersecurity included in managed IT services?

Usually a baseline is included, such as patching, antivirus or EDR, and basic email filtering. Full protection with 24x7 monitoring, phishing training, immutable backups and compliance documentation is often an add-on tier. Always ask a provider to list exactly which security controls are included in the monthly fee and which cost extra so you can compare proposals fairly.

Q: What is the cheapest way for a small business to improve cybersecurity?

Turn on multi-factor authentication for email, remote access and financial systems, keep systems patched, use a password manager and verify that backups are offsite and tested. These steps cost very little, often use features you already pay for in Microsoft 365, and stop the majority of everyday attacks that hit small offices on the Treasure Coast.

For most small businesses, cybersecurity cost works out to a per-user, per-month figure that scales with headcount, plus a few annual line items such as training, an assessment and cyber insurance. Widely reported ranges for a properly protected small office run from tens of dollars per user per month for core tools up to a few hundred dollars per user per year once monitoring, training and testing are included. The number moves with your industry, your data and how much you already have in place.

That is the honest answer, and it is also why two quotes for the same Vero Beach office can look so different. This guide breaks down where the money actually goes so you can compare proposals and set a budget that fits a 10, 25 or 100 person company.

What drives small business cybersecurity cost?

Every cybersecurity quote we write on the Treasure Coast is built from the same handful of ingredients. Understanding them tells you why the price is what it is.

Per-user and per-device tooling. Endpoint detection and response (EDR), email filtering, DNS filtering, password management and multi-factor authentication are all licensed per person or per machine. This is usually the largest recurring cost.
Monitoring and response. Tools generate alerts; someone has to watch them. A 24x7 security operations service that investigates alerts and isolates an infected laptop at 2 a.m. costs more than software alone, but it is where breaches actually get stopped.
Security awareness training and phishing simulations. Inexpensive per user, and consistently one of the best returns because most incidents still start with a click.
Assessments and testing. An annual vulnerability scan, a risk assessment for HIPAA or cyber-insurance purposes, or a penetration test are usually one-time or annual fees rather than monthly.
Backup and recovery. Technically a separate service, but no security budget is complete without it. Immutable, offsite backup is your last line of defense against ransomware.
Compliance overhead. Medical, dental, legal and any firm handling card payments or defense contracts will pay more for documentation, policies and evidence collection.

Firewalls, secure Wi-Fi and network segmentation are often quoted separately under business networking, but they belong in the same conversation.

What pricing models will you see?

Small businesses generally encounter three ways of paying for security:

Bundled into managed IT. Many providers, including us, fold a baseline security stack into the monthly managed IT services fee. Convenient and predictable, but read the inclusions carefully: baseline is not the same as complete.
Managed security as an add-on. A per-user monthly fee layered on top of IT support that adds EDR, 24x7 monitoring, email security and training. This is the most common model for offices between 10 and 100 people.
Project-based. One-time engagements such as an assessment, a remediation project or an incident cleanup. Useful for closing specific gaps, but it leaves you without ongoing eyes on the network.

A few vendors price by device rather than user. That can favor firms with many shared workstations, like a dental practice with operatory PCs, and penalize firms where every person carries a laptop and a phone.

How much should a 10, 25 or 100 person business budget?

Rather than invent a dollar figure, here is how the spend typically shapes up at each size, based on what we see across Indian River, St. Lucie and Martin counties.

A 10-person office

At this size the essentials are non-negotiable and inexpensive: MFA on email and remote access, EDR on every machine, filtered email, a password manager, patching and tested backups. Most 10-person offices are best served by a managed bundle where security is included rather than buying tools piecemeal. Expect the security portion to be a meaningful but not dominant slice of your monthly IT spend.

A 25-person office

This is where 24x7 monitoring and quarterly phishing training start to pay for themselves. You likely have a server or a growing Microsoft 365 tenant, a few remote workers and at least one line-of-business application worth protecting. Budget for an annual risk assessment as well, especially if you are in healthcare, law or accounting.

A 100-person company

At 100 seats you are buying at better per-user rates, but you also need more: network segmentation, privileged access controls, a written incident response plan, vendor risk reviews and probably a compliance framework such as HIPAA, PCI or CMMC. Many companies this size pair a co-managed arrangement with an internal IT lead, which changes the cost structure again.

Is cybersecurity worth the cost for a small business?

Yes, and the math is not close. Widely reported figures put the cost of a single ransomware incident, counting downtime, recovery, legal notification and lost business, well into the tens of thousands of dollars even for small firms, and far higher for practices that must notify patients. We have helped Treasure Coast businesses recover from incidents that would have been prevented by an MFA rollout costing less than a single month of the cleanup.

There is also a practical angle: cyber insurers now require MFA, EDR and offsite backups before they will write or renew a policy. Skipping the spend can leave you both exposed and uninsurable.

How to spend smarter, not just more

Fix the basics first. MFA, patching, backups and email filtering stop the majority of common attacks and cost the least.
Use what you already pay for. Microsoft 365 Business Premium includes Defender for Business and Intune. Many offices are paying for a third-party product that duplicates it.
Right-size monitoring. A 10-person nonprofit does not need the same service tier as a 100-person manufacturer with CMMC obligations.
Plan for hurricane season. Security and continuity overlap. A business that can operate remotely for a week after a storm is also harder to take down with an attack.
Get an assessment before you buy. A short review of your environment often reveals that half the tools on a quote are unnecessary, or that a critical gap was missed.
