Best Security Tools for an IT Team of One in 2026

Seven tools one IT person can run for 40 staff, with the monthly bill for each and the managed option that changes it.

Product links may be affiliate links. How we rate 7 tools compared
TL;DR

For 40 users with laptops, one IT person can run a core security stack for $496 a month on list prices. The stack is Bitwarden Teams, Duo Essentials, Microsoft Defender for Business, KnowBe4 awareness training, Cloudflare's free Zero Trust plan and Greenbone's free scanner.

Swap the endpoint line for Huntress Managed EDR and the bill becomes $825.50 a month. Huntress sells a 50-seat minimum on direct purchase, so 40 laptops pay for 50, and a 24/7 team watches the endpoints while your IT person sleeps.

Buy the managed line only if nobody on the team can answer an alert outside working hours. Otherwise, price the self-run stack first.

Toolradar data: Toolradar, the software directory we run, has evaluated 855 security tools for its October 2026 ranking. This page keeps seven that one person can run and prices each one for the same 40 users, from vendor pricing pages checked on 10 October 2026.

A team of one has no second pair of eyes.

When the IT lead is out sick, the laptops, the vault and the sign-in page keep running, so the stack has to work without someone on call.

1 Bitwarden Teams logo
Top Pick

Bitwarden Teams

The vault that holds the shared admin logins, with event log auditing and directory sync on the Teams plan.

Pricing
$4/user/mo billed annually: $160 a month for 40 users

Best for: One-person IT teams that need shared admin vaults and event logs without an enterprise contract

Pros

  • Teams covers centralized ownership, credential sharing, event log auditing, directory sync and SCIM provisioning, so the vault follows the directory.
  • Event logs give a record of who used a shared credential, which an IT lead needs when a contractor leaves.

Cons

  • Passwordless SSO and granular access control sit on Enterprise at $6 per user a month, a 50 percent jump on the Teams seat.
  • It is a business vault, not a device manager, so the laptop policy still lives in another tool.
2 Duo Essentials (Cisco Duo) logo

Duo Essentials (Cisco Duo)

Single sign-on and phishing-resistant MFA across the apps, with Trusted Endpoints included on the Essentials tier.

Pricing
$3/user/mo on Essentials: $120 a month for 40 users. Duo Free covers 10 users

Best for: Teams that need multi-factor sign-in and single sign-on across their apps from the first login

Pros

  • Essentials covers single sign-on, phishing-resistant MFA, passwordless sign-in and Trusted Endpoints at one per-user price, with no feature gate on the core job.
  • Duo Free gives 10 users strong MFA and the app integrations, enough to pilot the rollout with the IT lead and a few early adopters.

Cons

  • Duo Free stops at 10 users, so at 40 people the free tier covers only the pilot.
  • Complete device trust with endpoint protection checks sits on Premier at $9 per user a month, so Essentials checks less about the device than Premier does.
3 Microsoft Defender for Business logo

Microsoft Defender for Business

Next-generation antivirus and endpoint detection with automatic attack disruption, vulnerability management and monthly summaries.

Pricing
$3/user/mo billed yearly: $120 a month for 40 users, up to 300 users, 5 devices each

Best for: A one-person IT team that will act on alerts itself and wants endpoint protection without a SOC contract

Pros

  • One seat covers up to five devices per user, so a laptop, a phone and a tablet for the same person do not add three lines.
  • Vulnerability management and monthly security summary reports come in the same licence, covering the endpoints the seat protects.

Cons

  • Nobody watches the alerts overnight. The IT lead gets the detection and has to act in working hours or follow a written runbook.
  • The licence is written for up to 300 users, so a company above that size is outside the plan's range and needs another contract.
4 Huntress Managed EDR logo

Huntress Managed EDR

Managed detection and response with 24/7 threat detection, active remediation, free managed antivirus and incident reports.

Pricing
$8.99/endpoint/mo list ($7.99 at 100 endpoints). 50 seats direct: $449.50 a month

Best for: Teams that need a 24/7 team on the endpoints and can carry a 50-seat minimum on direct purchase

Pros

  • The 24/7 detection and response is in the rate, so an alert at 2 a.m. gets a human response rather than a queue for the IT lead.
  • Free managed antivirus is part of the rate, so the stack does not need a second antivirus line on the same laptop.

Cons

  • Direct purchase needs 50 seats per product, so a 40-laptop company pays for 50: $449.50 a month at the $8.99 list rate.
  • The standard term is 12 months, and the per-endpoint rate falls as volume rises, so the list rate is the ceiling of the quote, not the quote.
5 Cloudflare Zero Trust (free plan) logo

Cloudflare Zero Trust (free plan)

Secure web gateway and zero trust network access on the free plan, so the 40-person team pays nothing for either.

Pricing
Free for teams under 50 users. Pay-as-you-go is $7/user/mo at list

Best for: One-person IT teams under 50 people that want web filtering and app access without a VPN appliance

Pros

  • The free plan includes secure web gateway filtering and zero trust network access, which covers web filtering and remote access to internal apps at no cost for 40 users.
  • Nothing to install on a firewall or patch. The IT lead manages it from a web console, which suits a team with one person on the job.

Cons

  • The free plan is for teams under 50 users. At 50 users on pay-as-you-go list, the bill is 50 times $7, or $350 a month.
  • DNS-level filtering is not named on the free plan, so confirm it covers the blocking the team needs before relying on it.
6 KnowBe4 Security Awareness Training (Foundation) logo

KnowBe4 Security Awareness Training (Foundation)

Phishing simulations and training on a per-seat list price, with an Advanced tier at $3.75 a seat.

Pricing
$2.40/seat/mo at 25 to 50 seats on a 3-year term: $96 a month for 40

Best for: Companies that want phishing simulations and training with a per-seat list price printed on the page

Pros

  • The list price is printed per seat for 25 to 50 users, so the awareness line can go into the budget before any sales call.
  • The Foundation tier is the cheapest band, so a 40-person company sits on a published rate rather than a custom quote.

Cons

  • The price is per seat on a 3-year term. At 40 seats the commitment is $3,456 over three years, before the first phishing test runs.
  • The figures are list prices in US dollars, excluding taxes, and KnowBe4 says they may vary by region.
7 Greenbone Community Edition (OpenVAS Free) logo

Greenbone Community Edition (OpenVAS Free)

A free, self-hosted vulnerability scanner, with automatic scan setup, API access and support kept for the paid editions.

Pricing
Free of charge. You pay for the virtual machine it runs on. Commercial editions are listed in euros only

Best for: IT teams that can host a scanner on their own machine and accept no vendor support

Pros

  • No licence fee for the community edition, so the cost is the virtual machine and the time the IT lead spends running it.
  • It covers the scanning job that Nessus Essentials cannot do for a company, since that free tier is for non-commercial use only.

Cons

  • Automatic scan initialization, API access, remediation tickets and vendor support are not in the free edition, so the IT lead builds the scan schedule and the ticket trail.
  • Commercial editions are listed in euros only, so there is no US dollar figure to budget from, and the team should confirm the licence terms for company use before relying on it.

What it is

A security stack for an IT team of one covers the sign-in, the password vault, the laptops, the web traffic, the known flaws and the staff, with no security analyst on the payroll. The test is not which product wins a lab comparison.

It is what one person can finish in a working week, and what the stack costs each month.

Each line answers one job. Bitwarden holds the shared admin passwords, and Duo puts a second factor in front of the logins.

Defender for Business or Huntress protects the endpoints.

Cloudflare's free plan filters web traffic and gives remote access to internal apps for teams under 50 users, Greenbone scans for known flaws, and KnowBe4 trains the staff who click the phishing link.

Device management sits in best MDM software, and the endpoint options in depth are in best EDR and endpoint protection.

Why it matters

The bill follows the meter, and the meter differs by line. Bitwarden and KnowBe4 bill per seat, Huntress bills per endpoint with a 50-seat floor on direct purchase, and Cloudflare's free plan is for teams under 50 users.

For the same 40 people, the total moves by $329.50 a month on the endpoint line alone, so that one choice decides the budget meeting.

Minimums and terms matter as much as rates. KnowBe4 sells seats on a 3-year term, and its cheapest line at 40 seats is $96 a month, or $3,456 over the term.

Read the term, the seat floor and the renewal before the rate.

Key features to look for

What the licence meters
Per user, per endpoint or per seat on a fixed term. Those are three different bills for the same 40 people, so compare the unit before the rate.
Whether anyone watches the alerts
Self-run tools leave the alerts with the IT lead. Managed tools put a team on the endpoints, and that team is the line you pay for.
Minimum seats and terms
Huntress needs 50 seats on direct purchase, KnowBe4 sells on a 3-year term, and Cloudflare's free plan is for teams under 50 users.
What the free tier leaves out
Duo Free stops at 10 users, Greenbone's community edition has no vendor support or API, and Nessus Essentials is for non-commercial use only.

Pricing

Prices were checked on each vendor's own pricing page on 10 October 2026, in US dollars at list price. Every monthly line is the list rate times 40 users or endpoints, except Huntress, whose direct minimum is 50 seats.

Taxes, discounts and reseller prices are not included.

The self-run stack comes to $496 a month: the Defender, Bitwarden, Duo and KnowBe4 lines, with Cloudflare's free plan and Greenbone's community edition at no licence cost.

Swap Defender for Huntress and the total becomes $825.50 a month, or $9,906 a year. The managed stack costs $329.50 a month more, and it puts 40 laptops under a 24/7 team.

Methodology: we started from the security tools in Toolradar's October 2026 ranking and kept the ones one person can run without a security team.

A vendor that publishes no US dollar list price was left out of the budget.

Dupple has no test lab, so the figures are list prices and the page makes no claim from hands-on testing.

Mistakes to avoid
×Paying for two endpoint products. Huntress includes free managed antivirus in its rate, so a Defender for Business line on top is a second product on the same laptop.
×Using Nessus Essentials for company scans. The free tier covers 5 IPs and is strictly for non-commercial use, so a company cannot run its own network scans on it.
×Pricing 40 people as 40 seats. Huntress direct needs 50 seats, and Cloudflare's free plan is for teams under 50 users, so the total moves at the edges of the team.
×Reading the KnowBe4 rate as a monthly contract. The per-seat price runs on a 3-year term, so the budget line is $3,456 over the term at 40 seats.
Expert tips
→Count the seats before you read the rate. Forty laptops buy fifty Huntress seats on direct purchase, and KnowBe4 starts at a 25-seat floor on a three-year term.
→Read your Microsoft 365 plan first. If the tenant already includes endpoint protection, a separate Defender for Business line pays for the same laptop twice.
→Name the person who isolates a laptop and the person who answers an alert on a weekend, before you sign any endpoint contract. A team of one has no second person to call.
→Ask for the price with the term in writing. A monthly per-seat rate on a three-year term is a different contract from the same rate on a one-year term.
→Run the scanner on a schedule you can keep. Greenbone's free edition leaves scan setup and ticketing to the IT lead, so a scan nobody reviews is a report nobody acts on.

The bottom line

Start with the self-run stack. For 40 users it costs $496 a month on list prices, and every line is a product one IT person can run without a security team.

Bitwarden and Duo come first, because they protect the logins every other tool depends on.

Pay for the managed endpoint line only when someone must answer an alert outside working hours. Huntress is the one that does that job, and it raises the bill by $329.50 a month under its 50-seat minimum.

For the endpoint options in depth, see best EDR and endpoint protection, and for the managed case, best MDR services.

Frequently asked questions

What security tools does a one-person IT team need?

Start with a vault for shared admin logins (Bitwarden Teams), MFA and single sign-on (Duo Essentials), endpoint protection (Microsoft Defender for Business or Huntress Managed EDR), web filtering and remote app access (Cloudflare's free Zero Trust plan), a scanner (Greenbone's community edition) and awareness training (KnowBe4). On list prices for 40 users, the self-run version comes to $5,952 a year.

How much does a security stack cost for 40 people?

On list prices the self-run stack comes to $5,952 a year, with Defender for Business as the endpoint line. Swap in Huntress Managed EDR and the 50-seat minimum lifts the total to $825.50 a month, because a 40-laptop company has to buy 50 seats on direct purchase.

Is Microsoft Defender for Business enough without a SOC?

For a one-person team, it is the cheapest endpoint line on this list that includes detection and response, and it covers up to five devices per user and up to 300 users. Nobody else watches its alerts, though. If an alert at night must get a response before morning, the managed option is the fit, not the self-run one.

Is there a free security stack for a small team?

Partly. Cloudflare's Zero Trust free plan covers teams under 50 users, Duo Free covers 10 users with MFA and app integrations, and Greenbone's community edition is free of charge but leaves scan setup and ticketing to you. Nessus Essentials is free but limited to 5 IPs and non-commercial use, so a company cannot use it for its own scans.

Is Huntress worth it for 40 people?

It is worth it when someone must answer alerts outside working hours. Huntress lists $8.99 an endpoint a month, and its direct purchase needs 50 seats, so 40 laptops pay $449.50 a month, or $5,394 over the standard 12-month term. For that you get 24/7 detection and response and free managed antivirus.
