Rolling out MFA everywhere
By Sam Rivera, Founder, SentinelPanda · June 19, 2026 · 2 min read · Compliance
MFA is the single control that stops the most attacks for the least effort. The work is not turning it on — it is leaving no account behind.
Why it is the highest-return control
The majority of account takeovers start with a stolen or phished password. Multi-factor authentication breaks that chain: a password alone is no longer enough. No other single control stops as many real attacks for as little effort, which is exactly why every framework expects it and why it is usually the first thing a security questionnaire asks about.
Cover everything, not just email
The value of MFA is only as good as its coverage. Put it on your identity provider (so SSO carries it everywhere), email, cloud consoles, VPN or zero-trust access, source control, and any direct path into production. Anchoring access on a single SSO with MFA enforced is the cleanest way to get broad coverage from one control.
Choose stronger factors where you can
Not all factors are equal. Authenticator apps (TOTP) and hardware security keys resist phishing far better than SMS one-time codes, which can be intercepted or SIM-swapped. SMS is still vastly better than nothing — but for admins and high-value access, push for app-based or hardware factors.
Mind the accounts that hide
- Service and machine accounts that authenticate without a human — use scoped keys and rotation, since they cannot do interactive MFA.
- Break-glass / emergency admin accounts — protect with a hardware factor and monitor every use.
- Consoles reachable once you are on the VPN — being on the network is not authentication; enforce MFA at the app too.
Prove it, then keep it
Auditors want evidence MFA is enforced, not just available — the configuration that requires it and the absence of exempted users. Inventory every access path, enforce a second factor on each, and keep the configuration as evidence. SentinelPanda tracks MFA coverage as a control and flags the gaps before an assessor does.
