Backblaze Rolls Out Enterprise-Grade Security Upgrades with AI-Powered Anomaly Detection and Role-Based Controls

Backblaze has introduced a slate of enterprise security features designed to give customers more visibility and control over their cloud data, as organizations face increasingly complex cyber threats.

The San Mateo–based cloud storage provider’s latest platform update includes AI-driven Anomaly Alerts, a new enterprise web console, granular Bucket Access Logs, and expanded application key options. Backblaze says the upgrades strengthen its zero-trust security posture while simplifying administrative overhead for IT teams managing large-scale deployments.

"In today's evolving threat landscape, robust data security is paramount for businesses," said Gleb Budman, CEO at Backblaze. "This comprehensive update, which includes features like Anomaly Alerts, Bucket Access Logs, and the new enterprise web console, underscores our commitment to providing our customers with advanced tools to safeguard their critical information."

AI-Powered Threat Detection and Real-Time Monitoring

At the center of the update is Anomaly Alerts, now in private preview, which uses AI to flag unusual patterns of activity in B2 Cloud Storage buckets. By surfacing indicators of possible data exfiltration or unauthorized access, the system aims to help security teams catch breaches early.

Bucket Access Logs, which are now generally available, give enterprises deeper forensic capabilities by recording detailed operations within their storage environments. The logs are fully S3-compatible and can be integrated into existing security workflows for monitoring traffic and investigating suspicious behavior.

Backblaze has also added Event Notifications to deliver real-time alerts on object creation, deletion, or modification, bolstering customers’ ability to respond quickly to unauthorized actions.

Enterprise Web Console and Zero-Trust Access

The update introduces a private-preview enterprise web console paired with role-based access controls (RBAC). The console centralizes storage management for large organizations, allowing administrators to assign precise permissions in line with zero-trust principles.

Backblaze is also expanding its application key system. Multi-Bucket Application Keys let organizations issue a single key for multiple specific buckets, while Scalable Application Keys allow the generation of up to 10,000 short-lived keys per minute. Both measures aim to minimize potential attack surfaces by tightening access controls.

Compliance-Ready Features

Other additions include Custom Upload Timestamps, which allow customers to preserve original file creation dates for audit and legal purposes, and enhanced Cloud Replication and Object Lock integrations to strengthen ransomware protection and disaster recovery.

These features build on Backblaze’s existing SOC-2 certified architecture, server-side encryption, and immutable data options.

With enterprise data protection increasingly under scrutiny, Backblaze’s latest enhancements reflect the broader shift toward layered, proactive security models. By making these capabilities part of its open-cloud ecosystem, the company is signaling a push to compete more directly with hyperscale providers on both security depth and usability.
