Tenable Empowers erex with Continuous Cybersecurity Protection, Eliminating Costly Outsourcing

Tenable One enables erex to identify risk beyond vulnerabilities

April 9, 2025 · Tokyo, Japan

Tenable®, Inc., the exposure management company, today announced that erex Co., Ltd, a pioneer in renewable energy, has selected Tenable One to visualize risks beyond vulnerabilities, including misconfigurations, entitlement flaws, software weaknesses with confidence and maintain an environment ready to defend against cyberattacks.

Previously, the company relied on third-party cybersecurity specialists to detect whether the latest security patches were in place and find misconfigurations of its externally facing websites. While these assessments were comprehensive and detailed, they were costly, time-consuming, and limited to major website overhauls.

"With Tenable One, we now have the ability to unify security visibility, insight and action across the attack surface to understand our risk exposure and prioritize remediation efforts. This enhances our security posture and allows us to respond to threats proactively," said Mr. Ashish Gupta, Information System Department, erex Co., Ltd.

erex now has the technical and business context to distinguish which risk combinations constitute true exposure from a sea of noisy findings. The result is greater productivity from security teams and the ability to quickly generate summary reports that highlight critical and high-level issues for internal distribution.

"Visibility and proactive security are critical for managing risk," said Naoya Kishima, Country Manager at Tenable Japan. "We are proud to support erex in strengthening its cybersecurity defenses with Tenable One. By providing continuous threat exposure management (CTEM), Tenable One enables organizations to detect vulnerabilities in real-time and take decisive action before threats materialise."
