Phison and Cigent introduced a co-developed SSD platform that protects against ransomware and data theft with mechanisms built directly into the SSD's firmware. The drives even automatically encrypt and hide data from prying eyes in the event of an attack. These 'self-defending' drives will be available to everyone this year.

Antiviruses can detect already-known malware and analyze programs' behavior to detect potentially illicit behavior patterns. However, custom ransomware developed by hacker groups can remain undetected until it is too late, leaving systems open to attack. Therefore, it makes sense to protect data at the hardware level in many cases since this is usually secure from manipulation.

Cigent's Secure SSD K2 and Secure SSD Denali drives are based on Phison's PS5012-E12DC Crypto-SSD NVMe controllers and come with embedded firmware-based security features as well as Cigent Dynamic Data Defense Engine for Windows (D³E).

When a threat is detected, these drives automatically encrypt and hide sensitive files completely from the OS layer in 'safe rooms.' In fact, Cigent's drives can work in a 'Dual Mode' that splits an SSD into independent private/secure and non-private storage partitions that are invisible to one another and adversaries. Meanwhile, to protect data against physical theft, Cigent's drives also come equipped with attack detectors and sensors.

Furthermore, the Cigent Denali Secure SSD can actually detect ransomware (although it is unclear whether the firmware detects that a program encrypts data or the D³E software does it) and will support machine learning-based data protection later this year.
"The Cigent Secure SSD product family was developed by Cigent's team of experts in data recovery and cybersecurity working in close cooperation with the cutting-edge storage experts at Phison," said Greg Scasny, CTO of Cigent. "This combined team developed holistic data protection solutions with security built-in, making it virtually impossible for critical data and applications to be accessed from unauthorized sources. Software-only security is often easily bypassed, but our multi-patented, multi-layered self-defending storage can make critical data completely inaccessible and literally invisible to adversaries, giving customers peace of mind that their sensitive data and digital assets are safely stored and protected."

Previously only available to select government agencies and the U.S. army, Cigent's Secure SSDs will now be available to broader audiences. The K2 Secure SSD and D³E software are available now, starting at $299 for a 480GB drive. The Cigent Denali Secure SSDs will be available in Summer 2021. The drives come in 480GB, 1TB, and 2TB configurations.
