Libraesva ESG — Email Security Gateway
Semantic AI anti-phishing
Understands the meaning and intent of emails, not just keywords. Identifies impersonations, Business Email Compromise (BEC) and attacks generated with generative AI that bypass traditional filters.
Adaptive Trust AI
Learns your organisation's communication patterns and flags anomalies in real time. Does not use content for training and sends no data to the cloud — privacy and data sovereignty guaranteed.
Local sandboxing and URL analysis
Analyses attachments in a fully isolated sandbox within your environment. Every URL is inspected for hidden threats without sharing data with third-party services.
International recognition
Included in the Gartner Magic Quadrant 2025 for email security and ranked as an innovation leader in the Frost Radar for Email Security 2026. AV-Test Top Product certified.
Libraesva Email Archiver — Compliant Archiving
Tamper-proof retention
Every email is digitally signed with RFC 3161 timestamp and AES-256 encryption. Unalterable archives that guarantee data integrity for audits and legal disputes.
Instant full-text search
Search email content, attachments, metadata and headers across millions of messages in milliseconds. Fast eDiscovery for legal and compliance needs.
Automatic regulatory compliance
Custom retention rules, legal hold and complete traceability for GDPR, HIPAA, CCPA and SOX compliance. Over 80 granular permissions and a dedicated privacy officer role.
Integration with major platforms
Integrates with Microsoft 365, Exchange, Google Workspace and other platforms. Access archived emails via Outlook, web interface or mobile app.
Migration to Microsoft 365
From Exchange on-premise to Office 365
Complete migration of mailboxes, calendars, contacts and public folders from Exchange Server to Microsoft 365 with minimal impact on daily operations.
Hybrid Exchange + Office 365 mode
Configuration and management of hybrid environments where Exchange on-premise and Office 365 coexist. Ideal for gradual migrations or for the need to maintain part of the local infrastructure.
Migration from other platforms
Migration to Microsoft 365 from third-party email platforms — Zimbra, Lotus Notes, Google Workspace and others. Preliminary analysis, planning and complete data transfer.
Post-migration support
Verification of migrated data integrity, security policy configuration, user training and operational support to ensure a seamless transition.
Frequently asked questions
Microsoft 365's native filters block generic spam but are not designed to detect targeted attacks such as Business Email Compromise (BEC), sophisticated phishing and AI-generated threats. Libraesva ESG adds a layer of protection with semantic AI that analyses message intent, not just keywords.
Timeframes vary based on data volume and number of mailboxes, but a typical SMB migration takes 1 to 3 weeks, including preliminary analysis, data transfer and post-migration verification. The migration occurs without operational interruptions for users.
The GDPR does not explicitly require archiving, but it does require the ability to manage, retrieve and protect personal data contained in emails. A compliant archiving system with tamper-proof retention, fast search and legal hold is the most effective solution for meeting these requirements and handling potential legal disputes.
