Multi-factor authentication (MFA) asks users for two or more proofs of identity before they can reach an application, system or network. A password alone is something the user knows. MFA adds something the user has, such as a phone or security key, or something the user is, such as a fingerprint or face scan. Even if a password is stolen, the attacker still cannot sign in without the other factor.
For a business, MFA is one of the most effective controls against stolen credentials. It makes phishing, brute-force attacks and password reuse far less useful to an attacker, and it adds a check against misuse by insiders. It protects access to sensitive systems and remote workers, and it supports compliance work under regulations such as GDPR, HIPAA, PCI DSS and ISO 27001. It also builds customer trust when you protect the logins of customer-facing platforms.
MFA is most effective when it is enforced at one central sign-in point. Our single sign-on (SSO) solution lets you apply MFA once for all your applications, and our identity and access management service covers the wider picture.
Phishing emails are a common way passwords get stolen, so MFA pairs well with our email security and anti-phishing service.

Start with the logins that would hurt most if stolen: email, remote access and VPN, administrator accounts, finance and HR systems, and cloud consoles. Then extend it to all staff and to customer-facing portals. Plan for people who lose their phone, with a tested way to verify them and reset access, and keep emergency accounts that are tightly controlled.
MFA fails when people find it annoying and look for ways around it. Use the lowest-friction method that is strong enough, such as an authenticator app or passkey, and combine it with single sign-on so staff approve once instead of many times. Watch for push fatigue, where an attacker sends repeated prompts, by limiting prompts and using number matching where your product supports it.
MFA is a security control that asks for two or more proofs of identity before granting access, for example a password plus a code from a phone app. It stops most attacks that rely on stolen passwords alone.
2FA is a type of MFA that uses exactly two factors. MFA means two or more. In practice the terms are often used interchangeably.
It is better than a password alone, but SMS codes can be intercepted or redirected, for example through SIM swapping. Authenticator apps and hardware keys are stronger, so use SMS only where nothing better is possible.
Attackers try, for example by tricking users into approving prompts or by stealing session tokens. Phishing-resistant methods such as hardware keys and passkeys, together with user training, make this much harder.
Many standards, including PCI DSS and the access controls in ISO 27001, expect strong authentication for sensitive access, and MFA is the usual way to meet that. Your auditor confirms what applies to you.
Yes. We work from our base in Sharjah with businesses in Dubai, Abu Dhabi and the rest of the UAE. Most of the work can be done remotely, and we arrange site visits where they are needed.
