Multi-Factor Authentication (MFA)
Phishing-resistant, risk-aware authentication that stops account takeover without slowing your people down.
What it is
Multi-Factor Authentication requires users to prove identity with more than a password — something they have (a security key, a device-bound passkey, an authenticator app) or something they are. Enterprise-grade MFA goes further than a one-time code: it means phishing-resistant factors (FIDO2/WebAuthn, passkeys, certificate-based auth) and adaptive policies that weigh risk signals on every login.
Attackers have industrialised ways around weak MFA — real-time phishing proxies, MFA-fatigue push bombing, SIM swaps. The design goal today is not 'MFA enabled' but 'MFA that holds against the current attack playbook'.
The business case
Why enterprises need it
Compromised credentials are the #1 breach vector
Stolen and reused passwords remain the most common initial access technique in real breach data. Strong MFA is the single highest-leverage control against account takeover.
Not all second factors are equal
SMS codes and basic push approvals fall to phishing proxies and fatigue attacks. Phishing-resistant factors bind authentication to the legitimate site and device, closing the gap attackers now exploit routinely.
Cyber insurance and compliance now require it
Insurers, PCI DSS 4.0 and most enterprise procurement questionnaires now mandate MFA for remote access and privileged accounts. Gaps here directly affect premiums and deal eligibility.
User friction is a security risk
MFA that irritates users breeds exceptions, and exceptions become the breach path. Adaptive, risk-based authentication challenges users only when signals warrant it — keeping security high and friction low.
How we deliver
Cloud Armor's approach
Factor strategy matched to risk tiers
Passkeys or hardware keys for admins and high-risk roles, device-bound authenticator factors for the broad workforce, and a deliberate plan to retire SMS and legacy OTP.
Adaptive policy design
We build conditional access policies that combine device health, network context, geography and behavioural risk — stepping up authentication when risk rises and staying invisible when it doesn't.
Coverage of the awkward edges
VPNs, legacy protocols, shared workstations, frontline workers without corporate devices — the places MFA projects usually stall are the places we plan for first.
Rollout with adoption engineering
Phased enrolment, self-service recovery that doesn't become a social-engineering hole, and metrics on coverage and challenge rates so leadership can see the control actually operating.
Related practice areas
Technologies we deploy
MFA engagements typically build on the identity platform's native strong-auth stack (Duo, Okta, Microsoft Entra). Where a distinct MFA-specific vendor is preferred — e.g. hardware-key programs — we scope that separately.
