Automated Cryptographic Auditing & Threat Defense for Amazon S3.
Deploy tamper directly from AWS Marketplace. Continuous cryptographic File Integrity Monitoring (FIM), DSPM compliance, and early ransomware detection across multi-account AWS environments.
Why monitor Amazon S3 storage with tamper?
Amazon S3 is the backbone of modern enterprise data architectures. However, misconfigured bucket policies, compromised IAM roles, and dormant ransomware attacks represent critical blind spots that standard cloud monitoring tools fail to inspect at the object level.
Seamless Marketplace Deployment
Subscribe directly through AWS Marketplace with consolidated billing against your existing AWS commitments, EDP agreements, and simplified procurement.
Continuous Cryptographic FIM
Go beyond CloudTrail access logs: tamper computes cryptographic digests of S3 objects to detect silent modification, bit-rot, and unauthorized tampering.
Centralized Multi-Account DSPM
Audit security configurations across AWS Organizations, ensuring private bucket policies, Object Lock retention, and default encryption remain uncompromised.
Connect AWS S3 in under 2 minutes
tamper connects seamlessly via standard S3 read-only IAM credentials or dedicated role delegation with zero impact on production latency.
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 AWS S3 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.
Complete Visibility & Protection Across Amazon S3
Unified object-level threat defense protecting mission-critical AWS storage assets.
Automated S3 Object Fingerprinting
Maintains an immutable cryptographic record of object states. Detects silent alterations and unapproved drift across strategic data repositories.
AWS S3 Bucket Hardening & CIS Benchmarks
Continuously validates public block access settings, bucket ACLs, and IAM boundary permissions against CIS AWS Foundation Benchmarks.
Suspicious Access Burst & Blind Change Alerts
Identifies atypical data retrieval patterns and blind file modifications that bypass standard application gateways.
Entropy Qualification & Decoy Canaries
Tracks entropy spikes across S3 objects to expose active ransomware before mass destruction occurs, reinforced by canary honeytokens.
Protect your Amazon S3 buckets from silent tampering.
Deploy tamper with read-only IAM credentials in 2 minutes and maintain continuous cryptographic assurance across all your S3 storage.
Technical Architecture: Native S3 SigV4 & IAM Role Compatibility
tamper communicates natively over standard AWS S3 APIs utilizing AWS Signature Version 4 (SigV4) for zero-disruption integration.
1. Standard AWS SigV4 Protocol
Native S3 communication ensures complete compatibility with existing AWS pipelines, CloudFront distributions, and enterprise storage architectures.
2. Zero Overhead, Agentless Operation
tamper runs externally to your EC2 or EKS instances, executing scheduled background audits without impacting application compute resources.
3. Read-Only Non-Destructive Guardrail
Strictly read-only access models ensure tamper never alters S3 object metadata, user tags, or version histories.
