Duo Security Review 2026: Pricing, Pros, Cons and Alternatives

Price Essentials before Premier if a 20-person team needs a second factor and single sign-on. Premier is the remote-access edition, and most of that team only needs the prompt, the directory, and a trusted laptop.

Methodology: on October 16, 2026 we read Duo's edition page, its telephony credit docs, and the pricing pages for Okta, Microsoft Entra ID, JumpCloud and Ping. No trial account was opened, and each yearly figure is the printed per-user rate times the seats the block rule requires, times 12. Taxes, resellers and negotiated discounts are left out of those bills.

Toolradar data: Toolradar tracks 91 identity and access tools as of October 16, 2026, and it re-checked pricing on 69% of them in the prior 90 days, on its identity and access ranking.

The profiles next to this buy are Duo, Okta, JumpCloud and Entra ID.

If the identity provider is the thing you are leaving, the Okta alternatives page prices a 100-person bill. This page stays on Duo's own invoice, so the seat-block math stays in view.

The authenticator apps guide covers the phone app alone, a different purchase from a workforce directory.

Duo, sold as Cisco Duo, is a workforce access product in four editions: Free, Essentials, Advantage and Premier. Free is MFA plus the authenticator app for a team that still fits the free cap.

Essentials is the first paid step that adds a directory, single sign-on, phishing-resistant MFA, passwordless sign-in, trusted endpoints and unlimited applications. That is the edition to budget once a prompt is not the whole job.

Advantage is the detection edition, and it pays off only when someone will read the risk signals, not when the gap is still a missing second factor. Premier adds VPN-less access to private resources and a check that an endpoint protection agent is present, so price it to replace a VPN, not to add a prompt.

It is not a password vault, and the edition bullets do not list joiner-mover-leaver automation, so automated offboarding has to live in Okta or Entra.

Keep shared admin passwords in a password manager, and put a hardware key on the Duo admin account using the YubiKey review and the hardware key guide.

The pricing page offers a 30-day trial, credit-card payment and a later switch of edition, so you can test the prompt before a card is charged. Users enroll the authenticator app, and a normal login is a push or a passcode from that app.

The telephony docs say both spend nothing, while a text or a phone call spends credits, so enroll people on the app first.

Owners and billing admins buy extra credits in the admin panel, 1,000 at a time, and the panel shows the cost before the purchase. Duo publishes no dollar amount for that top-up, so you cannot budget the refill until you are already an admin.

If the balance hits zero, texts and calls stop, while push, app passcodes and hardware tokens still work.

Trusted endpoints, from Essentials up, can require a managed device before access, which stops a personal laptop from passing an approved prompt. Risk-based authentication, on Advantage, changes the check from live risk signals. Premier's remote access is a separate rollout from a prompt you already have.

For a network-layer alternative to that job, see the zero trust platforms guide.

Essentials is the edition to budget for a team that has outgrown the free cap and still only needs sign-in. The editions page lists one monthly rate per paid tier and does not show a cheaper annual sticker, so monthly is the published deal.

A 20-person team lands on an exact pair of 10-seat blocks: $720 a year on Essentials, $1,440 a year on Advantage and $2,160 a year on Premier. A 15-person team buys that same Essentials year, so $180 of it is five empty seats until you hire into them.

Five people stay on the free edition, at no charge, the only no-charge option here for a company that small. The same five on Okta still hit the workforce yearly minimum, which makes Okta a poor fit at that size. JumpCloud's SSO package, which bundles SSO, MFA and a password manager, is $660 a year for those five at the annual rate.

At 101 users the block size steps up, and blocks of 25 apply past the lower threshold. The order is 125 Essentials seats at $4,500 a year, and twenty-four of those seats are empty. That empty slice is $864 of the year, so do not cross the line for a single hire.

The editions page never states the block size where the two rules meet, so confirm it before you sign on that count.

Okta Starter is billed annually and includes SSO, MFA, Universal Directory and 5 workflows. Twenty Starter seats come to less than the $1,500 minimum, so the invoice is that floor rather than the seat math.

Okta Essentials, at $17 per user per month, is $4,080 a year for 20 people, and that is where Adaptive MFA, lifecycle management and access governance sit. Core Essentials, at $14 per user per month, is $3,360 a year for the same headcount.

Adaptive MFA on Starter is an add-on Okta does not price in public, and Professional and Enterprise are contact-sales.

Entra ID Free is included with Azure or Microsoft 365 and lists MFA, unlimited SSO to SaaS apps and directory sync.

Conditional Access is on P1, paid yearly, which is $1,680 for 20 standalone seats. P1 is also included with Microsoft 365 E3 and Business Premium, so those tenants may have no separate P1 line. P2 is $10 per user per month paid yearly ($2,400 for 20) and is included with Microsoft 365 E5.

Entra ID Governance is a separate yearly per-user product at the same published rate as P1, for customers who already have P1 or P2. Private Access is $5 per user per month paid yearly, or $1,200 for 20, and it does not replace the MFA edition by itself.

The Suite is $12 per user per month paid yearly, and Microsoft says a P1 subscription is required, so the sticker is not the whole invoice.

JumpCloud lists an SSO package at $11 per user per month billed annually ($13 monthly), which is $2,640 a year for 20 people. That is a much larger bill than Duo Essentials once you also want the bundled password manager.

A la carte MFA is its own line, and a la carte SSO is priced like that MFA line, not like the package. There is no free plan, the trial is the only unpaid window, and a suspended user stays billable, so a leaver left that way keeps costing a seat.

PingOne for Workforce prints Essential and Plus only on a 5,000-user annual contract: $180,000 a year and $360,000 a year at that floor. Divide the Essential floor by that user minimum and 12 months and you land on Duo's Essentials rate, which a small team cannot buy. Ping offers a workforce trial for prospects already at that scale.

Prices checked on October 16, 2026 on Duo's editions page, Duo's telephony docs (updated September 3, 2026), Okta pricing, Microsoft Entra pricing, JumpCloud pricing and Ping pricing.

Duo fits a company of 11 to 100 people that wants SSO and phishing-resistant MFA on a card, without an identity-governance project. The free edition fits a shop that only needs a prompt and still sits inside the cap.

Advantage fits the team that will use risk signals and identity threat detection. Premier fits the team replacing VPN access to private resources, and that team should also read the Cloudflare Zero Trust review before treating Premier as the only remote-access option.

Skip Duo when Microsoft 365 E3 or Business Premium already includes Entra ID P1, because you may already have Conditional Access. A second MFA product is then a second prompt for the same login.

Skip Duo when the requirement is access reviews or automated offboarding, which show up on Okta Essentials and on Entra ID Governance, not in Duo's edition bullets. Skip Premier if the only gap is a missing second factor, because you would pay for remote access you do not need.

A one-person IT shop pricing a whole stack, not only sign-in, can start from the security stack for an IT team of one.
