Platform
Your Defensible Data Foundation
The Microsoft Companion Smart Stack 3.0's Trusted Data Archive includes EAS for granular email archiving with full journal envelopes, HPCA for on-premise SMTP compliance capture, our new Arcivium for Azure deployment, and Z Cloud Archive for fully managed, cloud-native email archiving.
Immutable, Searchable, Compliant Storage for the AI Era
With our industry-leading journal archiving, our Trusted Data Archive [EAS, HPCA, Z Cloud] serves as an organization's data intelligence, security, and retention-policy governance layer, making its data from Microsoft Exchange and 365 safe, scalable, searchable, AI-ready, and economically productive.
Filling Critical Gaps in Microsoft's Email Solutions
Microsoft Exchange and Office 365 are powerful email platforms, but are not designed for long-term, tamper-proof archiving or comprehensive compliance. They lack native Compliance Archiving capabilities, which are essential for capturing and storing all emails in real-time for compliance and legal purposes. Zantaz Trusted Data Archive directly addresses this by providing a dedicated archive for permanent, secure, and compliant storage of all emails.
Ensuring Compliant Archiving [Compliance Archiving as a Service]
Microsoft does not support journaling within an Office 365 tenant, meaning journal mailboxes must be positioned externally. Zantaz Trusted Data Archive offers Compliance Archiving as a Service [CaaS/JaaS] that captures and preserves every email [sent, received, or deleted] in real-time, creating an immutable copy before any user or system can alter it. This ensures a legally defensible record of correspondence, which is crucial for adhering to regulations such as GDPR, FINRA, HIPAA, SEC Rule 17a-4, and the Sarbanes-Oxley Act.
Maintaining Journal Envelope Preservation
Unlike standard Microsoft 365 archiving, Zantaz retains the original journal envelope, which includes critical metadata such as BCC recipients and expanded distribution list membership. This information is often lost in native M365 tools but is essential for comprehensive legal and compliance investigations.
Facilitating Enhanced eDiscovery and Legal Readiness
Microsoft's eDiscovery tools can be complex and costly, with advanced features often requiring higher-tier licenses [e.g., Microsoft 365 E5]. Zantaz Trusted Data Archive provides fast and intuitive search capabilities, with no additional licensing costs, enabling businesses to quickly locate emails for legal or compliance purposes. It streamlines early case assessment and document review, enabling legal teams to perform efficient, defensible, and cost-effective discovery directly from the enterprise archive, reducing reliance on third-party vendors.
Optimizing Storage Costs

Microsoft 365 charges for additional mailbox storage, leading to escalating costs for large email volumes. Trusted Data Archive offloads older emails to a cost-effective, external archive, reducing storage costs while maintaining email accessibility. This also reduces the necessity for the most expensive Microsoft 365 E5 licensing if the primary need for E5 is driven by compliance and long-term retention.
Ensuring Data Security and Immutability
Emails stored natively in Microsoft Exchange and 365 are vulnerable to accidental deletions, user errors, and ransomware attacks. Trusted Data Archive provides immutable storage [tamper-proof and ransomware-proof], ensuring email data remains safe and unchanged, even in the event of a breach.
Streamlining Inactive User Management
Searching inactive mailboxes in Microsoft Purview can be challenging due to limited visibility, complex permissions, and fragmented workflows. Zantaz's Enterprise Archive Solution [EAS], a component of Smart Stack, allows inactive user data to be stored securely and compliantly without additional license fees, and remains fully discoverable for any search or compliance request, providing total Microsoft compatibility.
Providing Flexible Deployment Options
Trusted Data Archive offers diverse deployment options, including on-premises, hybrid, and hosted [including in your Azure tenancy with our new Arcivium for Azure] environments, accommodating various organizational infrastructures and preferences for data control.
Supporting Comprehensive Data Governance
Trusted Data Archive provides end-to-end data governance, regulatory compliance, and risk mitigation, as well as seamless eDiscovery and legal hold support. It ensures proper email archiving and enforces data retention policies, retaining emails only as long as necessary and automatically deleting them when no longer required.
