Security is no longer optional. If your organization is still using SharePoint on-premises server software for content management, it’s time to move to SharePoint Online. We can help you do it fast, safely, and with long-term success.

Critical Security Warning for SharePoint Server Users

Microsoft recently issued an emergency advisory for CVE-2025-53770, a zero-day vulnerability that is actively being exploited in the wild. This flaw allows remote attackers to execute malicious code on on-premises SharePoint Server environments, putting your entire data estate at risk.

Even with patches available, mitigation involves multiple complex steps, such as rotating encryption keys, updating SSL certificates, deploying new OS and SharePoint patches, and monitoring for indicators of compromise. It’s a heavy lift for most IT teams, especially as threats become more sophisticated.

This vulnerability highlights a larger issue: managing SharePoint on-premises infrastructure carries a growing set of risks, responsibilities, and security challenges. If your organization is still running SharePoint Server on-premises, this is your wake-up call. The risk is real, and the threat is active.

Why Move to SharePoint Online?

Migrating to SharePoint Online is no longer a nice-to-have; it’s a business-critical move. Microsoft’s cloud-first roadmap is clear, and SharePoint Online represents the secure, scalable, and integrated future of digital collaboration.

SharePoint Online offers automatic updates, built-in disaster recovery, and enterprise-grade compliance, all managed by Microsoft’s global security and operations teams. This removes the operational overhead of managing on-premises environments while significantly reducing risk.

What makes it even more powerful is its seamless integration with the Microsoft 365 ecosystem. Services like Microsoft Defender, Teams, OneDrive, Outlook, and Power Platform all work hand-in-hand with SharePoint Online, delivering a unified digital workspace.

And security? Microsoft’s cloud hosts over a billion users and hundreds of thousands of organizations, so any breach is rapidly addressed and resolved at scale. By contrast, on-prem environments must fend for themselves.

Organizations that migrate are also well-positioned to adopt Microsoft 365 Copilot, Microsoft’s AI-powered assistant. With secure, governed data in SharePoint Online, Copilot delivers relevant, trusted, and context-aware responses without external security risks. The result? A smarter, safer, and more productive workplace.

Security and Compliance: Not Just a Checkbox

Most data breaches aren’t caused by hackers; they stem from internal misconfigurations, excessive permissions, or lack of visibility into data flows. SharePoint Online gives you the governance tools you need to protect data from the inside out.

Microsoft Purview provides built-in classification, Data Loss Prevention (DLP), and lifecycle policies to help manage retention and secure sensitive information. SharePoint Advanced Management allows for detailed access control and reporting. When implemented properly, these tools enable organizations to meet strict compliance standards with far less manual effort.

At Creospark, we work closely with clients to set up governance policies, assign role-based access, and implement regular audit processes. Our goal is to turn compliance from a reactive requirement into a proactive, ongoing practice that builds long-term resilience.

Smart Data and Getting to the Cloud is the Key to Smart AI

AI is only as good as the data it’s built on. If your content is scattered, outdated, or poorly governed, even the best AI tools will struggle to deliver results.

Microsoft 365 Copilot relies on clean, accessible, and compliant data to provide accurate responses. By migrating to SharePoint Online, you enable a centralized platform for all your team and communication sites. With proper metadata, permissions, and retention policies in place, your organization can ensure that Copilot delivers only what’s relevant, improving trust and productivity across the board.

At Creospark, we guide clients through structured migration journeys that include data consolidation, removal of ROT (Redundant, Outdated, Trivial) data, and preparation for responsible AI adoption. This foundation enables successful Copilot rollout and adoption.
