Most businesses have Microsoft 365. Few have it configured securely. We fix that.
You've invested in Microsoft 365. Your team uses it every day for email, file sharing, and collaboration. But here's what most businesses don't realise: out of the box, Microsoft 365 is configured for convenience, not security.
Default settings leave gaps that attackers actively exploit. Basic multi-factor authentication can be bypassed. Email authentication is often misconfigured. Conditional Access policies that should be protecting your business simply don't exist.
The result? Your Microsoft 365 environment looks secure on the surface, but underneath it's leaving doors open that shouldn't be.
The attacks targeting Microsoft 365 in 2025 and 2026 aren't what they were a few years ago. Attackers have adapted.
Attackers aren't trying to break through your firewall anymore. They're logging in as your staff. Stolen credentials, phished sessions, and compromised accounts are now the primary entry point into Australian businesses. Once they're in, they look legitimateâbecause they're using real accounts.
Adversary-in-the-middle attacks can intercept authentication sessions in real time, bypassing SMS codes and authenticator apps. Device code phishing tricks users into authenticating attackers' devices. The MFA you set up two years ago may no longer be protecting you.
Attackers who gain access to a mailbox can send a fraudulent payment request within hoursânot days. They monitor email threads, wait for the right moment, and insert themselves into genuine conversations about upcoming payments. For professional services firms handling client funds, the stakes couldn't be higher.
When email authentication records aren't configured correctly, attackers can send emails that appear to come from inside your organisation. These messages bypass spam filters because they look legitimate. Your own domain becomes a weapon against you.
Our managed Microsoft 365 security services take your environment from âit's probably fineâ to genuinely secure. We configure, monitor, and maintain the security controls that default configurations leave wide open.
Conditional Access is the control centre for who can access what, from where, and under what conditions. Done right, it's your first line of defence. Done wrongâor not at allâit's an open door.
We configure policies that:
This isn't a one-size-fits-all template. We design policies around how your business actually operates.
Standard MFA using SMS or basic authenticator apps can be bypassed by sophisticated attacks. Phishing-resistant MFAâusing hardware security keys or passkeysâremoves this vulnerability entirely.
We help you move beyond checkbox MFA to authentication methods that actually withstand modern attacks, without disrupting how your team works.
SPF, DKIM, and DMARC are the technical standards that prove emails genuinely came from your domain. Misconfigured, they do nothing. Properly implemented, they stop attackers from impersonating your business.
We audit your current configuration, identify gaps, and implement strict policies that protect your domain from being used in phishing attacksâagainst you or anyone else.
Defender for Office 365 provides advanced protection against phishing, malware, and business email compromise. But the protection you get depends entirely on how it's configured.
We tune Safe Links, Safe Attachments, and anti-phishing policies to match your risk profile. We configure alerting so suspicious activity gets noticed, not buried in a dashboard no one checks.
Compromised accounts don't always announce themselves. Attackers often maintain access quietly, monitoring email traffic and waiting for the right moment to act.
We implement identity protection policies that detect risky sign-ins, impossible travel, and anomalous behaviourâthen take automated action before damage is done. Combined with regular access reviews, we ensure former staff and unused accounts aren't lingering vulnerabilities.
Before we change anything, we assess what you've got. Our security posture assessment examines your Microsoft 365 configuration against current best practices and the Essential Eight framework.
You get a clear picture of where you stand, what's at risk, and what to prioritiseâwhether you engage us to fix it or handle it internally.
For businesses handling sensitive client information, preventing data leakage is as important as preventing intrusion. Microsoft Purview provides data loss prevention capabilities that many businesses have licensed but never configured.
We implement policies that detect and prevent sensitive information from leaving your organisation inappropriatelyâvia email, Teams, or SharePoint.
We're not a call centre. When you work with Internacious, you get direct access to senior technical expertiseânot a ticket queue.
Your security concerns don't sit in a queue waiting for someone junior to attempt a fix before escalating. You talk directly to the people who understand Microsoft 365 security deeply.
We don't apply generic templates and call it done. We understand that a 15-person accounting firm operates differently from a 60-person engineering consultancy. Your security configuration should reflect how your business actually works.
We understand the Australian regulatory landscape, work in your timezone, and speak your language. No overnight tickets, no offshore support desks.
We begin with a thorough review of your current Microsoft 365 configuration. You'll receive a detailed report identifying gaps, risks, and priorities.
Based on the assessment, we develop a remediation plan that balances security improvement with business continuity. No big-bang changes that disrupt your operations.
We configure Conditional Access policies, harden email authentication, deploy phishing-resistant MFA, and tune Defender settingsâall with appropriate testing and staged rollout.
Security isn't set-and-forget. Our managed Microsoft 365 security services include ongoing monitoring, regular reviews, and continuous improvement as threats evolve and your business changes.
