The mainframe is a high-value target. Is yours protected by Multi-factor Authentication (MFA)?

Mainframes remain the backbone of the most critical systems in the world, but the way they’re accessed has changed. Passwords alone are no longer enough.

Why MFA matters on the mainframe?

Credentials remain the weakest link and a single compromised ID can create disproportionate business impact.
Password reuse, phishing, malware, and long‑lived privileged IDs are still common, even on the mainframe.
MFA significantly reduces the risk of credential‑based attacks.
Audit and regulatory pressure is increasing.
Standards such as ISO 27001, NIST, PCI DSS, SOX, Hong Kong CI Bill and Australian CPS234 now assume MFA is in place as part of modern security controls.
For example:
- Australia’s Prudential Regulation Authority (APRA) advice here, and
- More recently, the UK’s National Cyber Security Centre offers advice on implementing strong methods of MFA, here.

As a result, auditors are now asking: “Why isn’t MFA enabled on the mainframe?”.

So, how can Vertali APAC help?

We secure mainframe environments without disrupting operations, guiding you through a phased, risk‑based MFA rollout that targets the highest‑risk areas first:

Privileged and administrative users,
Remote and production access,
Emergency and break‑glass IDs,
Plus, developers, operations, support staff, batch IDs and service accounts.

Our specialists integrate MFA seamlessly with RACF and ACF2 (Top Secret as well), ensuring a smooth deployment with minimal impact. We focus on delivering measurable outcomes:

Reduced credential risk,
Stronger audit readiness, and
Security aligned with modern standards.

The bottom line:

MFA on the mainframe is no longer optional, but you don’t have to tackle it alone. Vertali APAC and its parent company, Vertali Ltd, can help you modernize controls quickly, efficiently, and without disruption.
