For a long time, Multi-Factor Authentication (MFA) was considered a best practice—a nice-to-have for security-conscious organizations. Today, it is an absolute necessity.
The death of the password
Passwords are fundamentally broken. Users reuse them across multiple services. They choose weak passwords. They are easily tricked into handing them over via phishing campaigns.
When a user's password is compromised, and there is no MFA in place, the attacker has immediate and unhindered access to everything that user can access. In an era of credential stuffing and automated attacks, relying solely on a password is negligence.
Cyber insurance and compliance
The shift from "best practice" to "mandatory" is largely driven by external forces.
- Cyber Insurance: Try getting a cyber insurance policy today without demonstrating that MFA is enforced across all critical systems. Insurers understand the risk and will either deny coverage or charge exorbitant premiums.
- Compliance: Major compliance frameworks (PCI-DSS, HIPAA, SOC 2) increasingly mandate strong authentication for any system handling sensitive data.
Verifying enforcement
It is not enough to simply say you require MFA. You must be able to prove it. This means having continuous visibility into the authentication posture of every user across every application.
The risk is especially acute for privileged accounts — read why admins without MFA are your single biggest risk for a deeper look at how a single unprotected administrator account can compromise an entire organization.
Kastrum continuously audits the MFA status of your users across your SaaS portfolio, providing a verifiable record of enforcement and immediately alerting you to any gaps in coverage. See what Kastrum does and explore our access security solutions.
