Edge-Ready S3 Security, FIM & DSPM for Cloudflare R2.
Protect your Cloudflare R2 AI datasets, web assets, and application buckets without egress fees. tamper connects natively to R2 S3 endpoints (`eu.r2.cloudflarestorage.com`) for continuous FIM, DSPM, and inline S3 Gateway protection.
Why secure Cloudflare R2 storage with tamper?
Cloudflare R2 has become the go-to zero-egress object storage for modern web platforms, AI training pipelines, and edge Workers. tamper adds the missing cryptographic FIM, DSPM posture scoring, and ransomware detection layer to R2.
Prevent Poisoning of R2 Datasets & Assets
Verify SHA-256 baselines on AI training corpora, RAG vector sources, and static production assets stored in Cloudflare R2 to catch unauthorized tampering.
Deep Entropy & DLP Scanning at Zero Bandwidth Cost
Because Cloudflare R2 charges $0 for egress bandwidth, tamper can perform deep content entropy checks and AI DLP classification without egress penalties.
Combine R2 with tamper S3 Gateway (DAM)
Pair R2 with tamper's Cloudflare Worker S3 Gateway (s3gw.com) to enforce real-time anti-wiper deletion quotas, CIDR/GeoIP filtering, and SIEM logging.
Connect Cloudflare R2 in under 2 minutes
tamper connects natively via standard Cloudflare R2 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 Cloudflare R2 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 Cloudflare R2
Unified FIM, DSPM, DAM, and DLP engineered specifically for Cloudflare R2 object storage.
Cryptographic Object Fingerprinting
Tracks SHA-256 baselines across all Cloudflare R2 objects, identifying unauthorized modifications and silent corruption.
Bucket Configuration & Access Controls
Continuously audits Cloudflare R2 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 Cloudflare R2 buckets.
Connect your Cloudflare R2 storage in minutes and maintain a tamper-evident cryptographic baseline across all your cloud assets.
Technical Architecture: Native S3 API Compatibility with Cloudflare R2
tamper communicates with Cloudflare R2 over standard HTTPS S3 endpoints (
1. Standard S3 SigV4 Protocol
Full interoperability with your existing Cloudflare R2 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.
