100% French Sovereign S3 Security & Backup Resilience for Leviia.
Combine Leviia's ultra-fast French sovereign S3 object storage with tamper's French cryptographic FIM & DSPM engine. Achieve extraterritorial immunity, NIS 2 compliance, and verified anti-ransomware backup integrity.
Why secure Leviia storage with tamper?
Leviia and tamper share the same DNA: 100% French sovereign technology built to protect SMBs, mid-caps (ETIs), and public institutions from ransomware without US Cloud Act exposure.
Zero Extraterritorial Exposure
Both your Leviia S3 buckets in France and your tamper security instance operate strictly under French and European jurisdiction (GDPR & NIS 2).
Cryptographic Verification of Object Lock
tamper continuously audits Leviia bucket immutability (Object Lock WORM & Versioning) and verifies SHA-256 hashes across your backup archives.
High-Frequency Audits Without Egress Penalties
Leverage Leviia's transparent pricing to run hourly integrity and entropy checks with tamper at a predictable monthly cost.
Connect Leviia in under 2 minutes
tamper connects natively via standard Leviia read-only S3 API credentials with zero disruption to your existing workflows.
Minimal credentials, zero infrastructure intrusion.
Connecting a bucket in tamper is completely agentless. You provide standard regional S3 credentials through the tamper web console, and automated baseline auditing begins immediately on the next scheduled cycle.
In your Leviia console, generate a key pair scoped strictly to Read-Only access on your target bucket.
Fill in Provider, Endpoint, Region, Bucket Name, and your Key credentials. tamper validates the connection instantly.
tamper takes the initial cryptographic snapshot and continuously monitors for drift, ransomware entropy, and posture changes.
Comprehensive Security Posture Across Leviia
Unified FIM, DSPM, DAM, and DLP engineered specifically for Leviia object storage.
Cryptographic Object Fingerprinting
Tracks SHA-256 baselines across all Leviia objects, identifying unauthorized modifications and silent corruption.
Bucket Configuration & Access Controls
Continuously audits Leviia bucket visibility, encryption settings, Object Lock, Versioning, and lifecycle rules against CIS security benchmarks.
Access Anomaly & S3 Gateway Protection
Monitors data access patterns and supports optional inline protection via the tamper S3 Gateway for real-time request filtering and anti-wiper quotas.
Entropy Qualification, AI Tagging & Canaries
Detects encryption spikes (~7.99 Shannon entropy), qualifies document alterations with local AI, and monitors stealth canary objects.
Elevate the cyber-resilience of your Leviia buckets.
Connect your Leviia storage in minutes and maintain a tamper-evident cryptographic baseline across all your cloud assets.
Technical Architecture: Native S3 API Compatibility with Leviia
tamper communicates with Leviia over standard HTTPS S3 endpoints (s3.eu-west.leviia.com) using AWS Signature Version 4 (SigV4).
1. Standard S3 SigV4 Protocol
Full interoperability with your existing Leviia pipelines, backup tools (Veeam, rclone, restic), and cloud-native applications.
2. 100% Agentless Operation
Audits run externally on your dedicated VM or tamper appliance without deploying any software inside your compute instances.
3. Strict Read-Only Boundary
Non-destructive cryptographic inspection ensures your object payloads, custom metadata, and version histories are never altered.
