Cloud infrastructure built for performance, security, and availability.

Yes. SharePoint and OneDrive often contain some of an organization's most important business information, making proper security, governance, and access management essential.

Calysto helps organizations review sharing settings, permissions, external access policies, user practices, data retention requirements, backup and recovery strategies, and overall governance controls. Our goal is to ensure information is accessible to authorized users while reducing the risk of accidental exposure, inappropriate sharing, data loss, or unauthorized access.

We also evaluate how SharePoint and OneDrive fit into the broader Microsoft 365 security strategy, including identity protection, multi-factor authentication, conditional access policies, data protection controls, and operational best practices.

By improving visibility, strengthening controls, and establishing clear governance standards, organizations can take advantage of Microsoft 365 collaboration capabilities while maintaining greater security, compliance readiness, and operational confidence.

Yes. Calysto helps organizations plan, execute, and support Microsoft 365 migrations with a focus on security, reliability, user experience, and long-term operational success.

Microsoft 365 projects often involve more than simply moving email. Successful deployments require careful planning around user identities, authentication, licensing, security controls, data migration, device management, application compatibility, and end-user adoption. Our team works to ensure that critical business data, communications, and workflows transition smoothly while minimizing disruption to day-to-day operations.

We can assist with Microsoft 365 migrations, tenant-to-tenant transitions, Exchange Online migrations, Microsoft Teams deployments, SharePoint and OneDrive migrations, identity integration, security hardening, and post-migration optimization. Throughout the process, we help organizations strengthen Microsoft 365 security, improve collaboration capabilities, and establish operational best practices.

Our goal is to ensure your Microsoft 365 environment is not only successfully deployed, but also secure, supportable, and aligned with the needs of the business.

In most cases, yes. Cloud services provide availability and convenience, but they do not always provide the level of backup, retention, recovery, and business continuity protection that organizations expect.

Many cloud platforms operate under a shared responsibility model, where the provider is responsible for maintaining the service itself, while the organization remains responsible for its data, user activity, security settings, and recovery requirements. Accidental deletion, ransomware, malicious insiders, synchronization issues, retention limitations, and configuration errors can still result in data loss or business disruption.

Calysto helps organizations evaluate backup and recovery requirements across Microsoft 365, SharePoint, OneDrive, email, cloud applications, servers, and critical business systems. We focus on ensuring that data can be recovered when needed and that recovery processes are tested, documented, and aligned with business objectives.

A strong backup strategy is not just about having copies of data. It is about ensuring the organization can restore operations quickly, recover important information, and maintain business continuity when unexpected events occur.

Yes. Calysto helps organizations manage, secure, and optimize Microsoft 365 environments as part of a broader cybersecurity and operational strategy.

Our team supports identity protection, multi-factor authentication (MFA), Conditional Access policies, secure email configuration, administrative role management, Microsoft Defender capabilities, Teams governance, SharePoint and OneDrive security, data sharing controls, backup and recovery planning, and ongoing platform administration. We also help organizations establish governance standards that balance security, productivity, and collaboration.

Because Microsoft 365 is often the primary platform for email, file storage, communication, and user identity, proper configuration and ongoing management are critical to reducing cybersecurity risk. We work to improve visibility, strengthen security controls, reduce exposure to phishing and account compromise, and support compliance and operational objectives.

Whether the goal is improving security, supporting compliance initiatives, enabling collaboration, or optimizing an existing deployment, Calysto helps ensure Microsoft 365 remains secure, manageable, and aligned with the needs of the business.

Yes. Calysto helps organizations deploy, manage, secure, and optimize Microsoft 365 environments as part of a comprehensive technology and cybersecurity strategy.

Our team supports Microsoft 365 administration, user and license management, Exchange Online, Microsoft Teams, SharePoint, OneDrive, identity management, security configuration, governance, backup planning, migrations, and ongoing operational support. We also help organizations improve collaboration, strengthen security controls, and establish best practices that support long-term success.

Whether you are implementing Microsoft 365 for the first time, migrating from another platform, consolidating multiple environments, or improving an existing deployment, we can help ensure the platform is configured to support both business productivity and cybersecurity objectives.

Because Microsoft 365 often serves as the foundation for communication, collaboration, file storage, and user identity, we view it as a critical business platform that should be actively managed, secured, and aligned with the organization's operational and compliance requirements.
