altus for government
PPM built for Microsoft GCC and GCC High
Federal agencies, defense contractors, and public sector organizations can't run most Project and Portfolio Management software in a government cloud tenant. Altus meets the requirements of both Microsoft's GCC and GCC High environments.
secure by design
Most software can't run here. Altus does.
Unlike other solutions, Altus runs entirely on the Microsoft Power Platform, inside your own secure Microsoft 365 tenant and the GCC or GCC High boundary. That means everything stays in Microsoft Dataverse, including native support for GCC High authentication, Microsoft Graph Government APIs, and Dataverse Government environments.
Built for how government programs actually run
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
Data sovereignty, not a footnote
All Altus data stays inside your own Microsoft 365 tenant, in Microsoft Dataverse. It never passes through Altus servers or any outside environment, whether you're in commercial cloud, GCC, or GCC High.
Audit-ready by default
Every update, decision, risk, and change is timestamped and attributed. When an audit, inspector general review, or oversight request arrives, your record already exists.
One source of truth for every tool
Altus is schedule-agnostic. It pulls data from Microsoft Project Desktop, Microsoft Planner, and Jira into a single portfolio view, so you don't have to force every team onto the same scheduling tool to get a unified picture.
Portfolio and strategic visibility
Aggregate program data into executive-ready dashboards for your leadership and oversight bodies, reflecting current status rather than a report assembled the week before a briefing.
For partners and systems integrators
If you're a systems integrator or reseller already selling into federal or defense accounts, Altus gives you a PPM platform to bring into deals that would otherwise stall at the compliance review. There's no separate government edition and no asterisk on the data sovereignty story you're already telling. It's the same Altus platform, deployed the same way, now validated for GCC and GCC High too.
the difference
GCC an GCC High
GCC
Federal Civilian - State & Local - Higher Education
GCC High
Defense Supply Chain - CUI /ITAR
Microsoft's government cloud comes in two tiers most organizations will encounter. GCC (Government Community Cloud) serves federal civilian agencies, state and local government, and higher education. GCC High adds stricter isolation and screening for organizations handling Controlled Unclassified Information (CUI) or International Traffic in Arms Regulations (ITAR) data, primarily contractors in the defense supply chain, not the Department of Defense's own dedicated cloud (see the FAQ below for that distinction).
Altus meets the requirements of both, so you don't have to choose between capability and compliance, or re-platform if your program moves from GCC to GCC High as requirements change.
Frequently Asked Questions
What is GCC High?
GCC High is one of Microsoft's most restrictive US government cloud environments, built for contractors in the defense supply chain and organizations handling Controlled Unclassified Information (CUI) or ITAR-controlled data. It adds screening, personnel, and data-handling requirements beyond standard GCC.
What's the difference between GCC and GCC High?
GCC serves federal civilian agencies, state and local government, and higher education. GCC High serves organizations with CUI or ITAR obligations, mostly in the defense supply chain. See our full comparison for detail.
Is Altus available in a GCC High tenant?
Yes. Altus supports native GCC High authentication, Microsoft Graph Government APIs, and Dataverse Government environments, and deploys inside your GCC High tenant the same way it deploys in commercial Microsoft 365, with no separate infrastructure and no workaround. The one thing that changes is how you grant access: commercial Microsoft 365 and GCC use standard Microsoft Public Cloud Consent, while GCC High requires Microsoft's separate GCC-High Consent process, which Altus is already registered for.
Does Altus support the Microsoft DoD cloud?
Not yet. The Department of Defense's own cloud sits at a further, more restricted tier above GCC High, built for DoD's internal environment rather than its contractor base. Altus supports GCC and GCC High today. If DoD-tier support matters for your organization, talk to our team and we'll factor it into the roadmap.
Do we need a different Altus license for GCC or GCC High?
Talk to our team about how your existing Microsoft government licensing maps to Altus's Project, Portfolio, and Strategy tiers. You likely already have the underlying Power Platform components included.
