Microsoft Defender, deployed and tuned by certified engineers.
Microsoft Defender is the unified threat-protection suite covering endpoint (EDR), email (MDO), identity (MDI), and cloud workloads (MDC) inside Microsoft 365 E5. GR IT Services deploys, tunes detection rules, integrates with Sentinel SIEM, and runs 24/7 SOC monitoring for US enterprises with a five-minute P1 incident SLA.

Indicative dashboard. Real client tenants vary by license and threat profile, the engagement model below applies to all of them.
Eight layers, one threat-protection platform.
Defender for Endpoint
Detection and response on the endpoint, with behavioral analytics, investigations that run themselves, and rules that shrink the attack surface. Tuned to the machines you actually own, with indicators and policies written for you.
Defender for Identity
Threat detection across both the directory on your own servers and the one in the cloud. Movement sideways through the estate, forged ticket alerts, visibility when somebody escalates their own privileges, all feeding the SIEM.
Defender for Office 365
Anti-phishing on mail, attachments detonated somewhere safe first, links rewritten, and protection against somebody impersonating your leadership. Tuned to how your company actually sends mail, with the false positives brought down through proper baselining.
Defender for Cloud Apps
An access broker sitting across your software subscriptions. It finds the tools nobody told you about, controls what happens inside a session, spots anomalies, and hands decisions back to conditional access.
Defender Vulnerability Management
Continuous scanning across every endpoint, with findings ranked by severity and by whether anybody is actually exploiting them, wired into patching so a finding ends in a fix rather than in a report.
Microsoft 365 Defender portal
One incident view spanning the whole suite. Hunting queries, playbooks that investigate on their own, and integration into our own operations center for round the clock cover.
Defender for Family / Individuals
The consumer version, for personal devices and family accounts. Identity theft monitoring, credit alerts, and protection carried across devices, which matters for staff using their own hardware for work.
Defender for Threat Intelligence
The Microsoft threat intelligence feed and its indicators pushed into your own operations. Tracking of specific adversaries, mapping of the techniques they use, and curated indicators wired into Sentinel so hunting can be proactive rather than reactive.

Four reasons clients pick us for the deployment.
80+ Defender tenants
Having seen it before counts for a great deal. We have tuned this across small companies, regulated firms and multi-tenant deployments, and we know which false positives recur and which configuration traps catch people.
Tuned, not just enabled
The environment gets baselined, the detections tuned, the false positives suppressed, and every change written down. What arrives out of the box is a starting point and never a destination.
24/7 SOC operations
Security operations running around the clock for American businesses. A critical incident has a senior engineer on it within five minutes. The same people who built the deployment are the ones watching it.
Audit-ready evidence
ISO 27001, NIST CSF, SOX reviews answered with Defender telemetry, configuration history, and incident response logs. Compliance-ready by default.
Defender deployments by sector.
Financial services
Firms answering to the SEC or to NYDFS Part 500, using this to meet the threat protection their regulator expects. Logs an examiner can read, and incident response coordinated with the regulator when it has to be.
Healthcare
Clinics, hospitals and physician groups protecting patient information, containing ransomware before it spreads, and reporting incidents in the way HIPAA requires.
Professional services
Law firms, accounting practices and consultancies. Email protection that understands confidentiality, loss prevention at the level of individual documents, and ethical walls held in place through the cloud application controls.
Tech and SaaS
Software companies using this as part of getting ready for SOC 2. Detection and response on endpoints, identity threat protection, and vulnerability management.
Retail and e-commerce
Retail groups protecting point of sale terminals, the administrative accounts behind their online store, and anything in scope for PCI, against both ransomware and account takeover.
Education
Schools and universities protecting student devices, faculty accounts and the examination systems against phishing and ransomware.
Cloud-side controls beyond endpoint.

The business case in eight cards.
Seamless deployment
Policies are delivered from the cloud through one console. No rebuilding an agent on every machine, and nobody driving to a site with a laptop full of installers. Most deployments finish inside two to six weeks.
Centralized management
The portal pulls endpoint, identity, email and cloud application security into a single console. One incident queue, one place to hunt, one set of policies to maintain.
Real-time protection
Behavioral detection, rules that shrink the attack surface, and remediation that happens on its own, all acting at the moment something executes rather than after tomorrow signature update.
Behavior-based detection
The detection analytics surface previously unseen and fileless attacks that no signature-based product can find. Tuned per environment so the administrative tools your own engineers use every day stop generating alerts.
Threat intelligence integration
The Microsoft intelligence feed, indicators from elsewhere and whatever you have written yourself, all consumed into the same detection layer, with adversary tracking built in rather than bolted on.
Cloud-powered protection
The detection logic runs in the cloud at a scale nobody could replicate locally. Machines stay light, and the telemetry comes back for correlation across everything you own.
Compatibility and scalability
Windows, macOS, Linux, iPhones and Android devices are all covered. One tenant or many. Fifty machines or five thousand, it is the same platform underneath.
Compliance and reporting
Evidence for ISO 27001, the NIST Cybersecurity Framework, SOX and PCI, packaged straight out of the telemetry. Audit ready without a project, with control mapping documentation produced on every engagement.
Done properly, this is a way of operating rather than a product somebody bought.
Most companies buy this, deploy it on the default policies, and never open it again. What follows is a noisy console, analysts who stop reading alerts, and a comfortable but entirely false sense of being protected. The point of running it properly is that it recedes into the background while still catching the things that matter.
- Reduce alert volume by 80%+ through baseline tuning
- Pair Endpoint + Identity + Email for full XDR coverage
- Operationalise threat-hunting queries, not just alerts
- Keep audit-ready evidence ISO / NIST CSF / SOX reviewers accept
- Hand off operations to a 24/7 SOC, not a ticket queue
- Re-tune quarterly as the threat landscape shifts

Managed SOC
Continuous
Monitoring around the clock, incident response when it is needed, a threat report every month and a tuning review every quarter. The people who built it are the people watching it.
See Defender across five core security workloads.
Endpoint EDR with behavioral detection
The endpoint product runs on every workstation and server, stopping malware before it executes and keeping the forensic telemetry an investigation needs afterward. Tuned against your own standard build so the administrative tools your engineers use daily stop raising alerts.
- Behavioral EDR with attack-surface reduction
- Custom indicators and live-response shell
- Managed via Intune or SCCM, single agent
- P1 incidents triaged within 5 minutes by SOC
Microsoft Defender, frequently asked.
Resources for security leads.
Microsoft Entra
Security built around identity first: single sign-on, multifactor, conditional access and control over privileged accounts. Very often deployed alongside this to cover identity properly.
Microsoft Sentinel
The log platform and the automation layer, both running on Azure. Sits alongside this for detection in one place, response without a human, and custom detections written at scale.
Cybersecurity audit
An independent audit, before the deployment or after it. A penetration test, an analysis of where you sit against the frameworks that apply, and a written program for closing the gaps.
