Rublon vs Protectimus
Rublon prices MFA per user with two paid tiers, EUR 2 and EUR 4 a month, and a free plan that stops at one protected user. Protectimus sells the same idea as a cloud service or an on-site platform, with a free plan for 10 users and USD plans from $33 a month. The practical split is how you want to buy: a fixed per-user rate with a 15-licence floor, or flat monthly plans plus separate charges for SMS and hardware tokens. Rublon says nothing about hosting, while Protectimus states both options.
Sebastiaan SmitsFounderVendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
Choose Rublon ifyou have at least 15 people to protect, want a published per-user euro rate, and can live without seeing hosting options on the pricing page. You also need Remote Desktop, VPN, SSH or AD FS coverage.
Choose Protectimus ifyou want to run MFA on-site or in a private cloud, or start free with up to 10 users and no card. You are also happy to read a plan table of users, resources and admins to find your real size.

Where they differ
Rublon 1 · Protectimus 4 · open 1- 01
Where the servers are allowed to sit
Protectimus offers a Cloud Service tab and an On-Premise tab, and says its platform can be deployed on-site or in a private cloud. Rublon's pricing page does not state hosting options, and its homepage is silent too, so we cannot say whether it offers cloud, self-hosted or on-premises. For a buyer with a rule about where authentication servers run, Protectimus answers the question and Rublon leaves it open until you ask its sales team, which slows a security review.

A flat EUR 2 against plans by user count
Rublon Business costs EUR 2 per user per month with a 15-licence minimum and multi-year discounts. Enterprise costs EUR 4 with a 300-licence minimum under a custom contract. Protectimus cloud plans are Starter at $33 for 23 users, Business at $111 for 77 users, and Custom at $2 per user. At about 77 users Rublon Business works out near EUR 154, though the currencies differ and cannot be compared exactly. Rublon also gives volume buyers multi-year discounts.
Depends on the buyer

One protected user or ten
Rublon MFA Free is free of charge but limited to 1 protected user, with community support only. It also leaves out the Authorized Networks, Remembered Devices and Geolocation policies. The Protectimus Free cloud plan covers 10 users and 1 resource with an unlimited trial period and no card needed. For a home office or a very small team, ten users is a far more usable starting point than one, and the lack of a card requirement lowers the barrier to a pilot.

What SMS and calls add to the invoice
Both products bill phone methods on top of the plan. Rublon charges phone credits for SMS Passcode, SMS Link and Phone Call on every plan, and phone support is an extra charge on the two paid tiers. Protectimus charges SMS at $2 per user per month, while SMART, BOT, MAIL and PUSH are shown as free. No per-credit rate for Rublon's phone methods is given in the text we saw, so they cannot be priced, which makes Protectimus easier to budget.

Connectors named on the home pages
Rublon lists native connectors and APIs for Windows and Active Directory, LDAP, RADIUS and SAML protocols, and Mobile Push, FIDO keys and OTP tokens, plus remote access integrations for Remote Desktop, AD FS, VPN and SSH. Protectimus lists an API with SDK libraries for Java, Python and PHP, SP-initiated SSO for Office 365, and a UniFi Controller link for Wi-Fi SMS authentication. Rublon covers more infrastructure by name, while Protectimus names more developer tooling, so check the list against your own servers.

Hardware tokens and trial terms
Protectimus prices hardware OTP tokens from $8.99 to $20.99 by model and volume, with its TWO token $3 cheaper when a year of service is paid in advance, and every plan includes a $25 initial balance. Rublon offers a Start Trial button on both paid tiers that falls back to the free plan, and no trial length is stated. Protectimus is more concrete here, and Rublon leaves the trial length unstated, so you cannot plan the evaluation window.

When neither fits
If you want one per-user price with no phone or token extras, neither page we read gives it. WatchGuard AuthPoint and Duo Security are two other options in our MFA list.
Rublon or Protectimus: questions
3 answersDoes Rublon's free plan work for a five-person team?
No, because the plan is limited to 1 protected user. It also carries community support only and leaves out three policy types. A team of five would need the Business tier, which has a 15-licence minimum.
Which one lets me keep authentication on my own premises?
Protectimus does, since its on-premise platform can be deployed on-site or in a private cloud, from $199 a month for 99 users. Rublon's pricing page does not state hosting options. Ask Rublon directly if a self-hosted setup is a requirement.
Where are the two companies registered?
Rublon sp. z o.o. gives a registered address in Zielona Gora, Poland, in its privacy policy. Protectimus Limited gives a Dublin, Ireland address, with company number 669809 in its privacy policy. Neither company names a parent on the pages we opened.
