DefenderBasic delivers multi-factor authentication, automated patching and endpoint protection. DefenderCore adds the four controls required to complete Essential Eight Maturity Level 1: application allow-listing, advanced email/phishing filtering, geo-restricted sign-ins and strict admin-rights control.
No. Unapproved programs are stopped by default, but employees can submit a request. Once IT approves it, the software is added to the allow-list within minutes, so essential tools keep working while unknown or risky files stay blocked.
Clean mail arrives at normal speed. Messages that fail authentication (SPF, DKIM, DMARC) or trigger phishing rules are quarantined.
Only if you choose to block them. During onboarding we create a safe list of trusted countries, IP ranges or individual accounts. Approved contractors are added to that list, so they can sign in without weakening overall security.
Yes. You can add individual modules—such as phishing-resistant user training—or upgrade to DefenderPro or DefenderElite for just-in-time privileged access, full-disk encryption, data-loss prevention and insider-risk analytics, without re-deploying the entire platform.
