Why ThreeSixFiveCyber

Security and compliance built around how you actually work.

Your users live in Microsoft 365—not in a server room. We design and operate a modern security program around that reality. From CSP licensing through managed SOC and compliance reporting, we help cloud-only organizations run a disciplined, evidence-ready security program without building a large internal team.

Microsoft-first

Built on the stack you already own

We go deep on Microsoft 365, Sentinel, Defender, Intune, and Purview—so you get more value from licenses you’re likely already paying for.

  • Centralized signal in Sentinel, tuned to your environment
  • Defender XDR for identities, email, endpoints, and SaaS
  • Intune-driven device hardening and drift management
Operator & advisor

Hands-on SOC with strategic guidance

We don’t just hand you dashboards. We triage, investigate, and guide response—then help you communicate risk and progress in business terms.

  • Clear reporting for leadership, boards, and customers
  • Guided incident response and recovery support
  • Roadmaps that balance risk, budget, and timing
Compliance-aware

Mapped to CMMC 2.0, NIST & CJIS

We align controls, monitoring, and evidence collection to your required frameworks—from CMMC 2.0 and NIST 800-171/800-53 to CJIS-related requirements for justice and public safety environments.

  • Policy baselines for Microsoft 365 and Intune
  • Evidence-friendly reporting for assessments
  • Support for DFARS and government-facing contracts

Core service pillars

Everything you need to secure a Microsoft-only environment.

Four tightly integrated pillars: Microsoft CSP licensing, managed Microsoft 365 operations, managed compliance, and a Microsoft-centric Managed SOC. Together, they give you a single accountable partner across licensing, operations, security, and evidence.

CSP Licensing

Microsoft Cloud Service Provider (CSP)

Streamline and optimize Microsoft 365 and Azure licensing with a security-focused provider. We support both SMBs and MSPs that need a partner who understands cloud-only security and compliance.

Microsoft 365 & Azure Licensing & support
Managed Microsoft 365

Managed Microsoft 365 (MSP)

Identity, email, Teams, SharePoint, and devices managed as a secure whole. We keep your tenant healthy, hardened, and aligned with Microsoft recommendations.

Identity • Email • Teams Secure by default
Managed Compliance

Managed Compliance (CMMC • NIST • CJIS)

Continuous monitoring, policies, control mapping, and evidence collection aligned to frameworks like CMMC 2.0, NIST 800-171, NIST 800-53, and CJIS—as your environment evolves.

CMMC 2.0 • NIST • CJIS Evidence-ready
Managed SOC

Managed SOC for Microsoft 365 (MSSP)

24/7 alert monitoring, triage, and incident support using Sentinel and Defender XDR, tailored specifically for Microsoft-only or light-hybrid environments.

FAQs

Common questions from SMBs, MSPs, schools, and local governments.

Here are a few of the questions we’re often asked when organizations are considering a Microsoft-centric managed security and compliance partner.

We are intentionally focused on Microsoft 365-centric environments and the compliance needs of SMBs, MSPs, schools, and local governments. Instead of bolting on yet another tool, we help you get full value from Microsoft 365, Sentinel, Defender XDR, Intune, and Purview—and connect those capabilities directly to your compliance story.
Yes—that’s our primary focus. We are built for cloud-only Microsoft 365 environments where there is no classic domain or network perimeter. Everything we do is designed around identity-based security, device posture, and cloud signal from Microsoft.
Yes. We can serve as your Microsoft-focused MSP (tenant and device management) and your MSSP (SOC operations and incident support). Some customers use all four pillars—CSP + MSP + managed compliance + managed SOC; others start with just one or two and grow from there.
Absolutely. While we do not replace your assessor, our services are mapped to CMMC 2.0 and NIST 800-171/800-53 practices. We help you select and configure Microsoft controls, operate the monitoring required for many technical practices, and generate reporting and evidence that supports your assessment.
Yes. We provide Microsoft CSP licensing for Microsoft 365 and Azure, including consolidated billing, license optimization, and integrated support. Because we also manage security and compliance, licensing decisions are directly informed by your risk and regulatory needs.
No. While we specialize in cloud-only environments, many customers start with a Microsoft 365 tenant and some on-premises servers or applications. We’ll integrate the most important legacy components into monitoring and help you plan a realistic migration path over time.
Pricing is typically based on a combination of protected users/endpoints, monitored tenants, and services in scope (for example, CSP + MSP + SOC + compliance). During a short discovery call we’ll estimate a range and then follow up with a detailed proposal so there are no surprises.
Yes. Many customers keep their existing IT provider or internal IT team and bring us in to add a dedicated, Microsoft-centric security and compliance layer. We can integrate with current ticketing, escalation, and communication patterns so everyone understands who does what.
