Secure your Backblaze B2 Storage with Automated Data Integrity & Threat Defense.

Why secure Backblaze B2 object storage with tamper?

Backblaze B2 delivers exceptional, cost-predictable cloud storage without egress penalties. But object storage is not immune to silent threats: stolen credentials, delayed encryption, and configuration drifts often go unnoticed until recovery is compromised.

01 / THREAT DEFENSE

Catch Silent Ransomware Encryption Early

Ransomware actors quietly encrypt backup objects over weeks to invalidate snapshots before demanding ransoms. tamper tracks object entropy and flags modification jumps within the very first hour.

02 / AGENTLESS ARCHITECTURE

Zero Overhead & 100% Agentless Auditing

No agents to install on servers, no kernel modules, and no sidecars. tamper audits your Backblaze B2 buckets over standard S3 endpoints without consuming your production compute or slowing file transfers.

03 / AUDIT-READY COMPLIANCE

Cryptographic Proof of Non-Alteration

Generate immutable SHA-256 integrity logs proving your Backblaze archives and customer datasets remained untouched, substantiating compliance audits for NIS 2, DORA, ISO 27001, and GDPR.

Connect any B2 bucket in under 2 minutes

tamper requires only standard read-only S3 credentials to begin continuous auditing. No bucket migrations, no DNS changes, and zero production downtime.

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.

01
Create a Read-Only Application Key

In your Backblaze B2 console, generate a key pair scoped strictly to Read-Only access on your target bucket.

02
Enter the 5 Connection Fields in tamper

Fill in Provider, Endpoint, Region, Bucket Name, and your Key credentials. tamper validates the connection instantly.

03
Continuous Integrity Auditing Starts

tamper takes the initial cryptographic snapshot and continuously monitors for drift, ransomware entropy, and posture changes.

Principle of Least Privilege: tamper strictly requires Read-Only permissions. tamper never requests write or delete privileges, preserving total customer data sovereignty.

Comprehensive Security Posture Across Every B2 Bucket

tamper combines multiple cybersecurity disciplines into a unified console designed specifically for cloud object storage.

FIM File Integrity Monitoring

Cryptographic Baseline & Drift Tracking

Calculates and audits SHA-256 integrity fingerprints across all B2 objects. Detects unauthorized file alterations, silent bit-rot, and unexpected file size variations with forensic timestamps.

DSPM Data Security Posture Management

Continuous Bucket Hardening & Risk Audits

Constantly audits B2 bucket configurations against cloud security benchmarks. Ensures private buckets are never inadvertently exposed to the public Internet and flags risky permissions.

DAM Data Access Monitoring

Traceability & Blind Modification Alerts

Correlates data modifications with authorized application activity. Flags "blind modifications" where objects change on B2 storage without a corresponding verified application trace.

DLP Data Loss Prevention & Ransomware Guard

Shannon Entropy & Canary Honeytokens

Calculates Shannon entropy on altered files (entropy approaching ~7.99 is a verified indicator of encryption). Deploys stealth canary objects in your B2 bucket that instantly trigger P1 incident alerts upon access.

Gain complete visibility over your Backblaze B2 buckets today.

Connect your first bucket in less than two minutes and maintain a tamper-evident cryptographic baseline of your critical cloud storage.

Technical Architecture: S3-Compatible API (SigV4) vs Native B2 API

tamper integrates with Backblaze B2 exclusively via its native S3-compatible API using AWS Signature Version 4 (SigV4), rather than Backblaze's proprietary native B2 JSON API.

1. True Standard S3 Interoperability

By communicating over standard S3 endpoints, tamper integrates transparently into your existing cloud storage architecture. Your backup software (Veeam, Commvault), migration utilities (rclone), and custom S3 applications continue operating normally without proprietary B2 SDK locks.

2. Standard S3 IAM Credential Mapping

tamper utilizes standard S3 authentication where the Backblaze Application Key ID maps directly to standard S3 accessKeyId, and the Application Key maps to standard S3 secretAccessKey. All audit requests compute authentic SigV4 authorization headers.

3. Transparent, Non-Destructive Audit Perimeter

tamper operates strictly as a read-only cryptographic auditor on your existing private buckets. tamper never alters user object metadata (such as X-Bz-Info headers) and never issues file deletion or lifecycle modification commands.
