SecNumCloud-Ready Integrity & Ransomware Defense for OVHcloud.
Deploy tamper across your OVHcloud High Performance Object Storage buckets with European sovereignty, automated FIM auditing, and instant threat alerting.
Why secure OVHcloud storage with tamper?
OVHcloud provides high-performance, European-sovereign object storage. tamper introduces continuous cryptographic file integrity monitoring and automated posture auditing to meet the highest defense and compliance standards.
SecNumCloud-Ready Architecture
Built to satisfy the most demanding European enterprise security requirements, NIS 2 directives, and GDPR mandates.
Predictable Cloud Economics
Audit massive data lakes without bandwidth penalties or volatile API query surcharges.
Sub-Minute Encryption Detection
Identify ransomware encryption attempts within the first hour through automated entropy and canary tripwires.
Connect OVHcloud S3 in under 2 minutes
tamper connects seamlessly via standard OVHcloud High Performance S3 credentials with zero disruption to active applications.
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 OVHcloud 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.
Sovereign Threat Defense Across OVHcloud Storage
Unified FIM, DSPM, and Ransomware defense engineered for European cloud storage.
Cryptographic Object Fingerprinting
Tracks SHA-256 baselines across all stored assets, identifying unauthorized modifications and silent bit rot.
Bucket Configuration & Access Controls
Verifies bucket visibility, access controls, and retention policies to maintain strict sovereign security.
Access Anomaly & Blind Modification Detection
Flags unusual data access activity and identifies modifications made outside standard application pathways.
Entropy Qualification & Honeytokens
Monitors entropy jumps to catch active ransomware attacks at the first altered object, reinforced by decoy canaries.
Elevate your OVHcloud storage cyber-resilience.
Connect your OVHcloud buckets in minutes and guarantee tamper-evident integrity across all your sovereign cloud data.
Technical Architecture: Native S3 SigV4 Compatibility
tamper connects to OVHcloud Object Storage via standard S3 API endpoints utilizing standard AWS Signature Version 4 (SigV4).
1. Standard S3 Protocol
Full compatibility with standard S3 tools, rclone, and custom applications without proprietary middleware.
2. Agentless Sovereign Operation
tamper operates without deploying local agents or sidecars, preserving application compute resources.
3. Read-Only Integrity Boundary
tamper maintains a strict read-only audit posture, never modifying file payloads, metadata, or version histories.
