Penta Security launches D.AMO onOS v5.0 for Linux data encryption

Penta Security has launched D.AMO onOS v5.0, a Linux encryption product aimed at protecting unstructured data, including logs, dormant files and decryption records. The release is meant to help organizations reduce breach impact by keeping sensitive data unreadable even if attackers break through security controls.

Why it matters: - Organizations face growing exposure from unencrypted logs, dormant data and weak key management. - D.AMO onOS v5.0 is designed to reduce the damage from breaches by encrypting data at the source and limiting readable plaintext outside the organization. - The launch reflects a broader shift toward data-centric security as AI-driven attacks make prevention alone less reliable.

What happened: - Penta Security announced D.AMO onOS v5.0, an unstructured data encryption solution for Linux environments. - The product covers encryption and decryption logs as part of its protection scope. - The company unveiled the release on Sept. 2, 2026, in Seoul, South Korea.

The details: - D.AMO onOS v5.0 encrypts legacy data and dormant data to eliminate unprotected areas that attackers could target. - The solution encrypts all log data, including encryption and decryption activity logs. - The platform securely records decryption history for post-incident auditing and forensic tracking. - Penta Security said the product is built to keep data unreadable even if attackers exfiltrate it. - The solution is designed to minimize performance differences before and after encryption in large-scale file system environments such as Network File System and Samba. - Penta Security said the product supports service continuity and system availability during failures. - D.AMO has been used in the Korean market for more than 20 years. - Penta Security became the first company in Korea to commercialize encryption technology in 2004. - The platform has been deployed across the public sector, financial services and private enterprises. - D.AMO has also expanded in global markets. - The platform integrated post-quantum cryptography algorithms standardized by the U.S. National Institute of Standards and Technology. - D.AMO also introduced a hybrid architecture that lets post-quantum cryptography and existing cryptographic systems run in parallel.

Between the lines: - The product launch signals that Penta Security is positioning encryption as a way to reduce blast radius, not just block intrusion. - The emphasis on logs, dormant data and recovery evidence suggests the company is targeting both prevention and incident response. - The post-quantum features show Penta Security is also framing the D.AMO line as future-ready for long-term cryptographic change. - Jihae Lee, Penta Security's chief compliance officer, said organizations need to reduce attack surfaces and keep data unreadable even after exfiltration.

What's next: - Penta Security is likely to keep pushing D.AMO in industries that handle sensitive data and need audit-ready encryption. - The company will also be able to market the platform around post-quantum readiness as cryptographic standards continue to evolve. - More information is available through the company's contact page.

The bottom line: - D.AMO onOS v5.0 is Penta Security's bid to make Linux data harder to steal, easier to audit and more resilient after a breach.
