Growing businesses juggle too many security tools with too little time, while attackers move freely across identities, devices, and cloud apps. As a Microsoft Defender solutions provider, ITRM configures, deploys, and manages Microsoft Defender for Business, Defender for Endpoint, and the combined Defender and Purview Suite for Business Premium, consolidating your security and data protection into one cost-effective platform. That means fewer tools, fewer gaps, and stronger protection, without adding to your IT team's daily workload.
Our Microsoft Defender solutions cover everything your business needs to move from siloed, reactive security tools to a single, proactive platform, matched to your existing Microsoft 365 licence rather than sold as a one size fits all package.
Consider what happens without a coordinated defence. An employee clicks a phishing email: with basic protection alone, the known threat is blocked, but there's limited visibility across devices and accounts. An attacker logs in using stolen credentials: sign-in risk might be flagged, but investigation is manual. With Microsoft Defender for Business and Defender for Endpoint in place, phishing is blocked and risky activity is detected automatically across email, identity, and device; suspicious sign-ins are detected, access is limited, and the account is protected without your team having to intervene manually. ITRM configures and manages this on your behalf, so your protection improves without adding to your team's workload.
For businesses that need data protection alongside security, Defender and Purview Suite for Business Premium consolidates both into a single, cost-effective package, built for Microsoft 365 Business Premium. Compared to buying separate tools, businesses adopting the suite have reduced costs by around 68%. Microsoft's own tier comparison sets Microsoft 365 Business Premium at $22 (approx. £16) per user per month, Defender Suite for Business Premium at $10 (approx. £7), the combined Defender and Purview Suite at $15 (approx. £11), and Microsoft 365 E5 at $57 (approx. £42), giving you a clear upgrade path as your compliance and data protection needs grow, rather than a jump straight to enterprise pricing. GBP figures are a rough guide only, converted at current exchange rates; check Microsoft's UK pricing for exact costs.
Generative AI is transforming how your business works, but it's also changing how fast sensitive data, customer records, IP, financials, legal documents, can be copied, shared, or leaked. For businesses that need data governance without a full endpoint security overhaul, Microsoft Purview Suite for Business Premium is available on its own at $10 (approx. £7) per user per month, automating data classification and retention, enforcing data loss prevention policies, and giving you the audit trail to prove it. It's built around three things: automating data security, simplifying controls with prebuilt templates and guided workflows, and streamlining compliance, so when sensitive data is detected in an upload, it's blocked and logged for audit, and repeat behaviour is automatically flagged for investigation by Insider Risk Management.
The risk of not doing this is concrete, not hypothetical:
Unprotected sensitive data, exposed through collaboration tools → leads to data leaks and compliance issues
Shadow AI use (unsanctioned tools), employees using generative AI without security controls → risks proprietary data exposure
Inconsistent governance, no centralised visibility or policies → makes it hard to audit or enforce standards
Regulatory exposure, increasing privacy and compliance obligations → risks fines and contractual penalties
Whichever tier you're on, Defender and Purview work together rather than in isolation when it comes to AI. Data Loss Prevention extends across Teams, browsers, endpoints, and Copilot itself, so an employee uploading data into an AI tool is detected and protected at the point it happens, not discovered after the fact. Paired with Defender for Endpoint's real time monitoring, that means both the device and the data are covered, closing the gap that point solutions in silos tend to leave open. ITRM configures these controls as part of every AI-aware deployment, whichever Defender or Purview tier you land on.
Consolidating your security tools around Microsoft Defender doesn't mean ripping everything out overnight. We take you through it in three stages, each building on the last.
The risk of doing nothing is well documented. Small businesses are 4 times more likely to be victims of a cyber security breach than large enterprises, and cyber attacks cost SMBs over $250,000 (approx. £185,000) on average, rising to as much as $7 million (approx. £5.1 million). One in three small businesses has already been a victim of an attack. Against that backdrop, consolidating security tools into Microsoft Defender isn't just a cost saving exercise, it closes the visibility gaps that let attackers move between email, identity, and devices undetected. That's the outcome ITRM's Microsoft Defender solutions are built to deliver: measurable risk reduction and cost control, without adding another disconnected tool to your stack.
Microsoft Defender for Business is Microsoft's cyber security solution for small and medium sized businesses, built into Microsoft 365 Business Premium. It brings antivirus, endpoint detection and response, and automated investigation and remediation together in one package, so growing businesses get enterprise grade protection without enterprise complexity.
Microsoft Defender for Endpoint is Microsoft's endpoint detection and response (EDR) technology, previously known as Windows Defender Advanced Threat Protection. It monitors devices in real time, detects suspicious behaviour, and can automatically isolate an infected device to stop malware or ransomware spreading before it reaches the rest of your network.
Defender blocks known threats with next generation antivirus, detects suspicious activity across email, identity, and devices, and automatically limits access and isolates affected accounts or devices. With Defender and Purview Suite for Business Premium added, it also detects when sensitive data is exposed, including through AI tools, and gives your IT team one integrated view instead of multiple disconnected alerts.
For most small and medium sized businesses, Defender for Business or Defender and Purview Suite for Business Premium covers the core risks: phishing, stolen credentials, ransomware, and AI-driven data exposure. Businesses with more complex compliance needs or larger user counts may need to layer on additional Purview or Microsoft 365 E5 capability, which ITRM can assess as part of a free security review.
ITRM configures and manages Microsoft Defender for Business, Defender for Endpoint, and the combined Defender and Purview Suite for Business Premium, matching the right tier to your existing Microsoft 365 licence and risk profile rather than defaulting to the most expensive option. For businesses that need data governance without full endpoint protection, we also offer Microsoft Purview Suite for Business Premium on its own.
If your business has devices connecting to email, cloud apps, and company data, from laptops to mobile devices, Defender for Endpoint's real time detection and automatic device isolation significantly reduces how far a single infected device can spread an attack. ITRM can confirm whether your current licensing already includes it.
Yes. ITRM provides the security advisor and deployment guidance to configure, tune, and manage Microsoft Defender on your behalf, so your team isn't stuck juggling alerts, licensing, and configuration alongside everything else on their plate.
