Power Pages (Portal) Development

Power Pages is Microsoft's low-code platform for building secure, external-facing business websites and portals. It is part of the Microsoft Power Platform and sits directly on Dataverse, so the portals you build are connected to your business data and processes rather than being disconnected marketing sites. With Power Pages, organizations create customer self-service portals, partner and vendor portals, knowledge bases, and application sites, fast, securely, and without standing up a full custom web stack.

The value of Power Pages is reach beyond your organization's walls. Tools like Power Apps serve internal users; Power Pages extends the Power Platform to customers, partners, and the public, with the authentication, security, and governance enterprises require. Because it is low-code and Dataverse-native, a portal that would traditionally take months of custom development can be delivered in a fraction of the time, while remaining maintainable. The key is designing it properly: secure authentication, clean data integration, responsive design, and a real user experience. ARC designs and builds Power Pages portals that are secure, on-brand, and genuinely useful to the people outside your organization who use them.

Power Pages combines low-code speed with enterprise capability:

• External portals on Dataverse. Portals read and write directly to your business data, so they are functional applications, not static pages.
• Secure authentication. Support for external identity providers, Azure AD B2C, and role-based access so the right users see the right data.
• Self-service experiences. Let customers, partners, and vendors submit requests, check status, and access documents without contacting your team.
• Responsive, branded design. Mobile-friendly, on-brand portals built with low-code design plus pro-code extensibility where needed.
• Power Platform integration. Trigger Power Automate flows and surface Power BI, connecting portals to your wider automation and analytics.
• Multi-language and governance. Multi-language support and the governance controls Power Pages provides for managed external access.

Common use cases include customer self-service portals, partner and vendor portals, application and registration sites, knowledge bases, and community or member portals.

ARC delivers Power Pages as a proper product engagement, not a template drop:

Discovery and design. We clarify who the external users are, what they need to do, and which business data and processes the portal must connect to, then design the experience and security model.

Data and Dataverse modeling. We structure the Dataverse tables and relationships so the portal reads and writes the right data cleanly and securely.

Authentication and security. We configure external authentication and role-based access so users only see and do what they should, a critical concern for external-facing sites.

Build and branding. We build the portal with low-code where it is efficient and pro-code where it adds value, applying your branding and responsive design.

Integration. We connect the portal to Power Automate, Power BI, and other systems so it is part of your wider business processes.

Launch and support. We test, harden, launch, and support the portal, then optimize it as usage grows.

External-facing portals demand extra rigor. ARC builds these practices in:

• Design security first. Authentication, authorization, and data access controls matter most when the audience is outside your organization.
• Model data deliberately. A clean Dataverse foundation is what makes a portal maintainable and performant.
• Focus on the user journey. Design around the specific tasks external users need to complete, not internal org structure.
• Build responsive and accessible. External users arrive on every device; design for mobile and accessibility from the start.
• Govern external access. Apply clear governance for who can access what, and monitor it.
• Plan to evolve. Treat the portal as a product that grows with feedback, not a one-time build.
