Managed security

Managed multi-factor authentication (MFA) and single sign-on (SSO)

MFA and SSO are two of the most effective ways to protect access to your systems. They reduce the risk of compromised credentials, support zero-trust access, and help meet obligations under ISO 27001, PCI DSS, the Essential Eight and CPS 234.

years testing for government and enterprise

CREST-accredited through CREST ANZ

We design, deploy and manage MFA and SSO with Duo, Microsoft Entra ID, Google Workspace, CrowdStrike Zero Trust, Okta and device-based checks.

We have more than 25 years of experience securing identity and access for government, financial institutions, utilities, legal firms and national retailers.

01 Overview

What are MFA and SSO?

MFA requires users to prove their identity with two or more independent factors. SSO lets users authenticate once with a trusted identity provider (IdP) and then reach multiple applications without logging in again. Together, they significantly reduce the risk of account compromise and streamline access.

Credential stuffing, phishing, MFA fatigue and session hijacking remain common causes of breaches.

MFA factors:
A well-configured identity layer helps with:
01

cloud adoption

02

remote work

03

partner and contractor access

04

privileged and administrative accounts

Regulators, insurers and frameworks commonly expect MFA for privileged accounts, remote access, cloud administration and payment-related functions. A well-configured identity layer is one of the fastest ways to improve your security posture.

02 Do I need it?

Do I need MFA or SSO?

If you rely on cloud services, remote work, SaaS applications or external partners, yes. Attackers actively exploit weak MFA settings, legacy authentication and misconfigured SSO, and a well-designed identity architecture is one of the most reliable ways to prevent account compromise.

You may need MFA and SSO if your organisation:

03 Platforms

MFA and SSO options and capabilities

Most organisations use one of three major MFA and SSO services. We support all three and tailor each to your environment.

OPTION 1
Duo (Cisco) MFA

Adaptive MFA that works across cloud and on-premises environments without redesigning your identity architecture.

  • push, hardware keys, passkeys and biometrics
  • conditional access based on device health, IP reputation and risk
  • user-friendly enrolment and self-service
  • integrations for VPNs, SSH, RDP, web apps and cloud services
  • reporting, alerting and behavioural insights

We design policies that balance security with usability and avoid unnecessary prompts.

OPTION 2
Microsoft Entra ID SSO and MFA

Microsoft’s identity platform, built into Microsoft 365 and Azure, and the natural choice for Microsoft-centred organisations.

  • SSO to Microsoft 365 and SaaS applications via SAML and OIDC
  • Conditional Access policies based on user, device, location and risk
  • MFA with Microsoft Authenticator, FIDO2 passkeys and Windows Hello for Business
  • risk-based sign-in protection with Entra ID Protection
  • just-in-time admin access with Privileged Identity Management

We configure Entra ID so policies are tight for administrators and high-risk sign-ins, and low-friction for everyday users.

OPTION 3
Okta Identity Cloud

Vendor-neutral SSO and MFA for mixed environments, legacy applications and complex partner ecosystems.

  • centralised SSO for cloud, on-premises and custom applications
  • adaptive MFA with contextual and behavioural checks
  • lifecycle and provisioning workflows
  • high-availability architecture and strong APIs
  • integrations with AWS, Google, Microsoft, CrowdStrike and others

We deploy and optimise Okta for flexible orchestration, strong admin controls and logging that serves SOC operations.

04 Why dotSec

Why choose dotSec for MFA and SSO

We have set up commercial SSO with SAML, WS-Fed, OIDC and OAuth for more than a decade, and implemented MFA (mainly with YubiKeys, and other mechanisms) for about as long.

01
We operate identity platforms, not just install them

We design and run secure identity platforms, so we understand the operational realities behind your MFA and SSO strategy.

02
Certified engineers

Our engineers hold certifications across Microsoft 365, Azure, Google Workspace, AWS, CISSP, PCI DSS and ISO 27001, and configure identity systems that reduce risk while keeping staff and partners productive.

03
Evidence-based policies

We avoid one-size-fits-all configurations that lead to MFA fatigue, bypass paths or poor usability. Your policies stay accurate, effective and grounded in evidence from our SOC.

05 FAQ

MFA and SSO FAQ

What is MFA?

Multi-factor authentication requires two or more independent proofs of identity before access is granted: usually something you know, something you have, or something you are. It significantly reduces the risk of account compromise (ACSC guidance on MFA).

Single sign-on lets a user authenticate once with a trusted identity provider and then access multiple systems without logging in again. It improves security by centralising authentication and reducing password sprawl (NIST SP 800-63-4 Digital Identity Guidelines).

Often, yes. PCI DSS v4.0.1 (Requirement 8.4), the Essential Eight from Maturity Level One, ISO 27001 and APRA CPS 234 all require or strongly expect MFA in some form. Even where it is not mandated, it is one of the most effective controls you can apply.

Not when it is configured well. Combined with SSO, MFA can reduce friction overall. Modern methods such as push prompts, passkeys and biometrics take seconds and significantly reduce the risk of account takeover.

Credential theft, phishing, password reuse, brute forcing, session hijacking and unauthorised access attempts. Even if a password is compromised, MFA stops most attackers getting in.

What next?

Improving identity security does not have to be disruptive or expensive. We start by assessing how staff, contractors and systems authenticate today, then design an MFA and SSO approach that fits your workflows.
