Plume Security launches DataFenz to stop data theft and ransomware in real time

Plume Security introduced DataFenz on June 9, 2026, positioning the product as a data detection and response platform that can monitor, block and recover from theft and encryption attacks in seconds. The company is targeting organizations that need faster containment across on-prem and cloud storage, especially in regulated industries.

Why it matters: - Data theft and ransomware can trigger business disruption, extortion, encryption and regulatory exposure. - Plume Security is pitching DataFenz as a data-layer defense that closes gaps left by endpoint, network and perimeter tools. - The platform is designed to respond automatically in seconds, which matters as attackers use AI to speed up attacks.

What happened: - Plume Security released DataFenz, a Data Detection & Response product, on June 9, 2026. - DataFenz monitors data access and activity to identify malicious behavior such as data theft and unauthorized encryption. - The product is built to detect and respond to attacks in real time without user intervention.

The details: - DataFenz inspects data in place, blocks exfiltration in real time and can recover instantly. - The platform gathers forensics during an attack for incident responders and forensic investigators. - Plume Security says the real-time forensic collection is especially important for regulated industries facing fines and reporting requirements after customer data exfiltration. - DataFenz works across on-prem and cloud data storage, including servers, network attached storage, hypervisors and cloud object storage. - The product includes dynamic alerting, revocation, SOC integrations and autonomous quarantines. - DataFenz is designed to enforce controls and prevent execution to reduce exfiltration compared with DSPM, DLP and backup-based approaches. - The product is positioned as a last line of defense against execution, encryption and data theft. - Plume Security included a website for more information: the company's announcement - Plume Security also listed social links for LinkedIn, Bluesky and YouTube.

Between the lines: - The launch reflects a broader shift from tools that mainly detect or score risk toward tools that try to stop active attacks before data leaves the environment. - Plume Security is framing the product around automated containment, not just alerts, which suggests the company sees current response workflows as too slow for modern attacks. - The baseball-bat analogy underscores the company’s message: alarms alone are not enough if attackers are already inside the perimeter.

What's next: - Plume Security will likely push DataFenz as an operational layer for organizations that need faster response to ransomware and exfiltration attempts. - Adoption will depend on whether security teams see value in autonomous blocking and quarantine across mixed storage environments. - Plume Security’s next challenge is proving that DataFenz can reduce real breaches without disrupting legitimate data access.

The bottom line: - Plume Security is betting that AI-speed attacks require AI-speed defense, with DataFenz positioned as a real-time stopgap between detection and damage.
