Full Microsoft stack replacement -- Office, email, MDM, identity, security. We deploy it, manage it, or hand you the keys. Starting at a fraction of M365 costs.
A complete enterprise IT stack built on open-source software. No licensing fees. No vendor lock-in. You control the data.
Replaces: Microsoft 365 / Office
With: OnlyOffice + Nextcloud
$0/user vs $23/user
OnlyOffice provides the same ribbon-style interface your users already know, with native support for .docx, .xlsx, and .pptx files -- not converted copies, but actual Microsoft format editing. Nextcloud adds file sync, version history, shared folders, and real-time co-editing. Combined, they deliver the same collaborative document workflow as SharePoint and Office 365 without the $23/user/month subscription. We've migrated organizations with 50,000+ documents and zero format corruption.
Replaces: Exchange Online
With: Zimbra or Mail-in-a-Box
Self-hosted, you own it
Zimbra provides full Exchange ActiveSync compatibility, which means Outlook desktop, Apple Mail, and every mobile mail app connects natively without reconfiguration. Shared calendars, contact syncing, resource booking, distribution lists, and enterprise-grade spam filtering with SpamAssassin and ClamAV are all included. Your email stays on infrastructure you control -- no third party scanning your messages for ad targeting or compliance exposure. We handle the migration with zero downtime using MX record cutover with parallel running.
Replaces: Microsoft Intune
With: Fleet MDM (osquery-based)
Sub-30s reporting vs hours
Fleet MDM is built on osquery, Facebook's open-source endpoint visibility framework used by enterprises managing millions of devices. Unlike Intune -- where compliance checks can take 4-8 hours to propagate -- Fleet returns real-time query results in under 30 seconds. Policy enforcement, software deployment, vulnerability scanning, and automated remediation across Windows, macOS, and Linux from a single dashboard. No per-device fees, no enrollment caps. Organizations switching from Intune consistently report faster incident response and dramatically better visibility into their fleet.
Replaces: Entra ID / Active Directory
With: Keycloak + Samba AD
Passkey-ready, no per-user fees
Keycloak is the identity platform behind Red Hat SSO, used by government agencies, banks, and Fortune 500 companies. It supports SAML 2.0, OpenID Connect, and LDAP out of the box -- meaning every SaaS application that works with Entra ID works with Keycloak. Samba AD provides full Active Directory compatibility for Group Policy, domain joins, and Kerberos authentication. Together they deliver MFA, passkey support, conditional access policies, and single sign-on for unlimited users at zero per-user cost. Entra ID P2 charges $9/user/month for features Keycloak includes for free.
Replaces: Microsoft Defender
With: Wazuh (SIEM + EDR)
Open-source XDR, unlimited agents
Wazuh combines SIEM, EDR, and vulnerability detection into a single platform that rivals Microsoft Defender for Endpoint P2 ($5.20/user/month) and Sentinel combined. File integrity monitoring catches unauthorized changes in real time. Vulnerability scanning identifies unpatched software across every endpoint. Threat detection rules map to MITRE ATT&CK framework. Built-in compliance dashboards cover HIPAA, PCI-DSS, GDPR, NIST 800-53, and CIS benchmarks. No per-agent fees means you can monitor every device, server, and container without worrying about cost-per-endpoint math. Organizations running Wazuh alongside Fleet MDM get security telemetry that Microsoft's stack can't match at any price tier.
Replaces: ServiceNow
With: GLPI + AI automation
Full ITSM at $0 license
GLPI provides enterprise ITSM capabilities that compete directly with ServiceNow (which starts at $100/agent/month). Ticket management, asset inventory, SLA tracking, change management, knowledge base, and self-service portal are all included. We layer AI-powered triage on top -- incoming tickets are automatically categorized, prioritized, routed to the right team, and pre-populated with suggested solutions from your knowledge base. Average ticket resolution times drop 30-40% in the first quarter. Hardware and software asset management is built in, giving you a single pane of glass for your entire IT operation.

We migrate one service at a time, with full rollback capability at every phase. Zero downtime, zero data loss.
Full audit of your current Microsoft environment -- license inventory, user workflows, application dependencies, data volumes, compliance requirements. We produce a detailed migration plan with specific cutover dates for each service. You sign off before any work begins.
Provision hosting infrastructure (your preferred cloud or our US-based data centers). Deploy Keycloak for SSO and Samba AD for directory services. Configure MFA, conditional access policies, and SAML/OIDC integrations for all existing SaaS applications. Users get new SSO credentials that work alongside existing Microsoft logins during transition.
Deploy Zimbra, configure domains, and migrate all mailboxes with full history. MX records are cut over with zero downtime using parallel running -- both systems receive mail during the transition. Calendar events, contacts, distribution lists, and shared mailboxes are all migrated. Users can continue using Outlook if preferred.
Deploy Nextcloud and OnlyOffice. Migrate all SharePoint and OneDrive content with folder structures, permissions, and version history preserved. Map shared drives and team sites to Nextcloud Groups. Users access files through web, desktop sync client, or mobile app. Document editing works immediately with all existing Microsoft format files.
Deploy Fleet MDM and Wazuh across all endpoints. Enroll devices via automated scripts -- no user interaction required. Configure compliance policies, vulnerability scanning, and alerting. Set up SIEM dashboards for real-time threat monitoring. Validate HIPAA/SOC2/PCI-DSS compliance posture against regulatory checklists.
Deploy GLPI with AI triage, configure ticket workflows, and import asset inventory. Conduct user training sessions and produce video walkthroughs. Run parallel operations for one final week. Decommission Microsoft services only after full validation. For Build & Transfer clients, hand over all credentials, documentation, and runbooks. For Managed clients, transition to ongoing 24/7 monitoring.
A 180-person multi-site healthcare organization was facing $85,000/year in Microsoft licensing after the July 2026 price increase -- up from $62,000. Their Microsoft E3 + Defender P2 + Entra P2 stack was expensive but their compliance auditor flagged gaps in their data residency controls because patient data was stored across multiple Microsoft cloud regions.
We deployed FreedomStack in 10 weeks: Zimbra for email, Nextcloud + OnlyOffice for documents, Keycloak + Samba AD for identity, Fleet MDM for devices, and Wazuh for security monitoring. All patient data now resides on dedicated US-based infrastructure they control. Their HIPAA audit score improved from 74% to 96%. Wazuh's compliance dashboards gave their security team real-time visibility they never had with Defender.
Four phases. Every step documented. Zero surprises.
Free cost analysis of your current Microsoft spend. We map every license, identify redundancies, and project 3-year total cost of ownership for both paths. You get the numbers before you commit to anything.
Custom stack architecture tailored to your organization. We match your workflow, integrate with existing systems, and plan the migration with minimal disruption. Every integration point is documented before we write a single config file.
Phased rollout with zero downtime. We build the new stack, migrate data, test everything, then cut over one service at a time. Full rollback capability at every step. Users experience no interruption -- parallel running ensures both systems work until you're ready to switch.
Ongoing managed services or complete hand-off -- your choice. Managed clients get 24/7 monitoring, automated updates, and helpdesk support. Build & Transfer clients get complete documentation, runbooks, and optional retainer support. No forced lock-in either way.
Choose the model that fits your organization. Both include full deployment and migration support.
Best for: Organizations that want the savings without the operational burden.
Best for: Organizations with internal IT teams who want full control and ownership.
Barely. OnlyOffice uses the same ribbon UI as Microsoft Office with full .docx/.xlsx/.pptx compatibility. Nextcloud has a familiar file-sharing interface similar to SharePoint. Email works with Outlook and mobile mail apps. The transition is designed to be as seamless as possible -- most users won't realize they're no longer on Microsoft infrastructure. In our experience, 90% of end-user support tickets in the first month are "how do I find X" questions that resolve within minutes, not "this doesn't work" issues.
Yes. HIPAA, SOC 2, PCI-DSS, and GDPR compliance are all achievable with proper configuration. Wazuh provides audit logging and compliance dashboards with pre-built rule sets for each framework. Encryption in transit (TLS 1.3) and at rest (AES-256) is standard across every component. The advantage: you control the data, so GDPR data residency and deletion requirements are actually easier to meet than with cloud providers. Many organizations find their compliance posture improves after migration because they have better visibility and more granular control over where data lives and who accesses it.
Gradual migration is the recommended approach. Most clients start with email (easiest and highest-impact), then file storage, then endpoint management, then identity. You can run hybrid for as long as needed -- some services on Microsoft, some on FreedomStack. There's no pressure to rip everything out at once. Some organizations keep certain Microsoft services (like Teams for external collaboration) while replacing everything else. We design the architecture to support whatever hybrid approach makes sense for your situation.
Full portability is built in. All data is in standard formats -- Maildir for email, standard file formats for documents, LDAP for directory. You can export everything and move back to Microsoft at any time. We'll even help you with the reverse migration if needed. No lock-in, no hostage-taking, no proprietary formats. This is fundamentally different from the Microsoft approach: try canceling M365 and exporting your Exchange data, SharePoint content, and Intune policies simultaneously. With FreedomStack, every piece of data is in an open format you can take anywhere.
That's the entire point. Microsoft announced 28-40% price increases effective July 2026 for Business Premium, E3, and E5 plans. For a 100-user organization on Business Premium, that's roughly $13,000 more per year -- every year, compounding as they continue raising prices. FreedomStack uses open-source software with zero per-user licensing, so your costs don't change when Microsoft adjusts pricing. Infrastructure hosting costs are predictable and negotiable. Organizations that switch before July 2026 avoid the increase entirely and lock in savings from day one.
Managed FreedomStack includes a 99.9% uptime SLA with 24/7 monitoring, automated failover, and daily backups with 30-day retention. Our infrastructure runs in US-based data centers with redundant networking and power. Email specifically has a 99.95% SLA because of the critical nature of business communications. Build & Transfer clients manage their own SLA based on their hosting provider -- we'll help you architect for whatever availability target you need, including multi-region failover for 99.99% uptime.
Yes. Fleet MDM manages Windows, macOS, Linux, iOS, and Android. OnlyOffice and Nextcloud have native mobile apps for iOS and Android with offline editing capability. Zimbra supports ActiveSync for native mail apps on all platforms. Keycloak provides mobile-friendly SSO with biometric authentication support. The entire stack is designed for the modern hybrid and remote workforce -- your users can work from any device, anywhere, with the same security policies enforced regardless of location or device type.
We'll analyze your current Microsoft spend, show you the 3-year savings, and map out a migration plan. No obligation, no sales pitch.
