When looking for a reliable multi-factor authentication (MFA) solution, it’s easy to get lost in the variety of options available on the market. To help navigate these choices, we continue our comparison series by examining how Protectimus stacks up against other well-known authentication vendors. In this article, we compare Protectimus and RSA. Both companies offer strong authentication solutions, but they approach the problem from different angles. RSA is positioned more broadly as an enterprise authentication and access platform with a strong passwordless and identity-centric direction, while Protectimus focuses on practical MFA flexibility built around open OATH standards, broad deployment choice, and straightforward implementation. This distinction matters because the right choice often depends less on which vendor is “better” in absolute terms and more on what an organization is trying to achieve. Companies building a broader identity, passwordless, and access ecosystem may lean toward RSA. Companies looking for flexible, standards-based MFA with strong OTP coverage, deployment control, and lower operational complexity may find Protectimus a stronger fit. Protectimus is based on open OATH standards such as HOTP, TOTP, and OCRA, which can simplify integration, migration, and long-term interoperability. RSA, in contrast, offers a broader enterprise platform with stronger emphasis on phishing-resistant passwordless authentication, federation, and identity workflows across cloud, hybrid, and legacy environments.

Server-Side Component Key Difference: RSA offers both cloud and on-premises deployment options as part of a broader enterprise authentication and access portfolio. Protectimus offers both a fully cloud-based MFA service and a comprehensive on-premise MFA platform built around the same practical OATH-based approach. RSA RSA provides cloud and on-premises authentication solutions for enterprise environments. Its current offering is broader than traditional MFA alone and includes passwordless authentication, SSO, adaptive access, help desk verification, and additional identity-related workflows. This makes RSA attractive for large organizations with complex authentication requirements, especially those modernizing workforce access across cloud and legacy environments. Its broader scope can be a major advantage for enterprises standardizing access controls across many systems, although it may be more than some companies need if their main goal is to deploy flexible MFA quickly and with lower complexity. Protectimus Protectimus offers clients a choice between a Cloud MFA Service and a Self-Hosted On-Premise MFA Platform. This flexibility suits both organizations that want a managed cloud service and companies that...
Multi-factor authentication (MFA) is a well-known and effective measure of protecting access to user accounts. MFA helps to reduce the number of attacks associated with stolen login data. Due to the use of two or more different authentication factors, it’s almost impossible to access the account even if an attacker has the user’s login and password. However, attackers constantly find new ways to bypass two-factor authentication, often exploiting human factors. One of such new growing threats based on human factor is the MFA fatigue attack. Let’s explore what an MFA fatigue attack is and how to counter it. What Is an MFA Fatigue Attack? An MFA fatigue attack is a type of social engineering technique in which an attacker repeatedly triggers authentication requests, typically through push-based MFA, in order to overwhelm the user. MFA fatigue attacks are also called MFA bombing, MFA push bombing, MFA prompt bombing, or MFA push spam. The main goal of this type of attack is not to steal a one-time password, but to make the user approve a login request themselves. In this scenario, the attacker already has valid credentials (a username and password). Instead of attempting to bypass MFA technically, they rely on persistence, timing, and psychological pressure to gain access. This makes MFA fatigue fundamentally different from classic MFA bypass techniques such as phishing, brute force, keyloggers, man-in-the-middle, or SMS interception. How MFA Fatigue Attacks Work? A typical step-by-step breakdown of an MFA fatigue attack looks like this: Credential compromise. The attacker obtains a valid username and password, often through techniques such as phishing, credential leaks, or malware. Repeated login attempts. The attacker initiates multiple login attempts that trigger MFA push notifications. Notification overload. The victim receives dozens of unexpected approval requests within a short period of time. Accidental approval. Due to fatigue, distraction, or confusion, the user taps “Approve” or “Yes” just to stop the notifications. Successful access. The attacker gains legitimate access, with logs showing a valid MFA-approved session. Why Push-Based MFA Is Vulnerable to MFA Fatigue? Push-based MFA is popular because of its convenience. A single tap is often all that’s required to complete authentication. However, this low friction also introduces risk. Push notifications often: Provide little context about the login attempt; Can be triggered repeatedly without meaningful limits; Rely entirely on user judgment at the moment of approval....
In response to new challenges, Protectimus has developed a powerful means of protection against auto-filling, injecting, and other types of malicious software that manipulates and modifies data during transactions. There are different ways in which such software can work; for example, the recipient is changed during a transfer as an unsuspecting user enters a one-time password sent via an SMS message. The problem is that this user...
