# tamper (https://tamper.one) > Protect what matters, detect what changes. tamper is a sovereign European, agentless, AI-assisted, provider-agnostic object-storage security platform (FIM, DSPM, DAM, DLP) developed by SIENNA (Lille, France) that detects the first signs of ransomware on S3-compatible buckets on infrastructure you control. - Full LLM documentation: https://tamper.one/llms-full.txt - Markdown version of any content page: append `.md` to any URL (e.g., `https://tamper.one/what-is-a-dspm.md`, `https://tamper.one/tamper-vs-varonis.md`). ## Four Core Disciplines - **FIM (File Integrity Monitoring)**: Continuous SHA-256 cryptographic fingerprinting, object drift tracking, audit history, and IoC hash matching across S3 buckets without installing agents. - **DSPM (Data Security Posture Management)**: Automated bucket configuration scoring (Block Public Access, Versioning, Object Lock WORM, SSE/KMS encryption, Replication, Lifecycle rules, CORS), CIS benchmark compliance, FinOps storage optimization visibility, and security option Auto-Fix. - **DLP (Data Loss Prevention & Ransomware Detection)**: Shannon entropy calculation on modified objects (entropy ~7.99 flags encryption), OCR + LLM AI analysis of modified documents, automated S3 object security tagging, DLP reports, and stealth Canary honeytoken objects. - **DAM (Data Access Monitoring & S3 Gateway)**: Real-time inline S3 API proxy (`s3gw.com`) providing zero-latency request authentication (AWS SigV4), anti-wiper deletion quotas, path/prefix DLP locks, GeoIP & CIDR IP filtering, and SIEM logging. ## Pricing & Plans (Exact Official Rates) - **Genesis (€30 / month)**: 1 bucket, up to 100K objects, Daily audit frequency, Manual audit possible, 1 third-party integration, FIM (File Integrity Monitoring, IoC matching on audited objects, Data Metrics, Audits History), DSPM (Configuration scoring, CIS benchmark, FinOps visibility), runs on Your VM, 5 days/week support, Monthly commitment, 30-day free trial. - **Monolith (from €200 / month)**: 1 to 10 buckets, up to 10M objects, Up to hourly audit frequency, Manual audit possible, tamperOne Access, Up to 3 third-party integrations, Full FIM + DLP (Entropy Check, AI analysis of modified objects, AI tagging, DLP reports, Canary objects) + DAM (Data Access Monitoring, S3 Gateway) + DSPM (including Optimization Opportunities & Auto-Fix of security options), runs on Your VM, 5 days/week support, Monthly commitment, 30-day free trial. -
