The modern, sovereign alternative to Varonis

Zero agents, sidecars, or plugins to install on your storage buckets or cloud virtual machines. tamper deploys in minutes without altering existing infrastructure.

Only standard S3 API credentials are required. Connect your buckets in under 5 minutes with zero architecture modifications or downtime.

tamper uses contextual AI to analyze file modifications, evaluate operational impact, and differentiate benign team activity from malicious ransomware encryption.

tamper automatically applies custom metadata tags to analyzed objects, allowing downstream SIEM, SOAR, and backup tools to immediately recognize asset criticality and integrity state.

Real-time detection of high-velocity modifications, off-hours batch deletions, and anomalous tampering with historical data, the defining signatures of modern cloud ransomware.

Continuous configuration audits evaluating Object Lock, Versioning, SSE Encryption, Replication, Lifecycle Policies, and Access Logs into an actionable security score.

Scans S3 bucket contents to evaluate object counts, classification tags, and exposure levels.

Tracks who accesses what, when, and from where to detect mass deletions, privilege escalations, and configuration downgrades.

Builds tailored S3 access policies to block public permissions and eliminate risky access paths.

Identifies and remediates configuration drifts, adjusting default roles against framework recommendations.

Sends alerts when sensitive files are modified, deleted, or shared externally.

Compares asset metadata against known breach sources to identify files at risk of prior exfiltration.
