Singapore, 2 September 2025 – In a bold move to address rising threats in cloud security, Singapore-headquartered cybersecurity software company InsiderSecurity announces the launch of CSX — an innovative cloud security solution that addresses the user security gaps left open in M365 and other SaaS.

Under the shared responsibility model in cloud security, both cloud service providers (eg M365) and users are jointly responsible for security, but users are often unaware of the areas of security that are under the users’ responsibility, nor do they know how to monitor for such user risks. CSX addresses this.

Developed in Singapore and an award winner from the Cyber Security Agency of Singapore, CSX delivers unparalleled visibility into suspicious M365 user activity, excessive permissions, and accidental data leaks —helping IT teams detect breaches before they spiral.

“The modern enterprise perimeter has vanished. The real risks are now internal—inside shared folders, mailboxes, and admin roles,” said Jonathan Phua, CEO of InsiderSecurity. “CSX shines a light on what used to be blind spots, especially in Microsoft 365.”

Cloud Data in M365: The New Breach Frontier

M365 has become the digital backbone for businesses—but with its growth comes new challenges. A 2024 study found that over 60% of organisations experienced a cloud-related security incident, with misconfigurations and insider actions as top culprits.

CSX focuses deeply on M365 data security, with built-in detection for:

• Suspicious activity based on user behavior

• Accidental data leaks or malicious data theft in Sharepoint/OneDrive

• These address top-of-mind business questions such as:

• Where is our sensitive data today?
• Is any folder or file shared by mistake?
• Are departed staff or insider threats accessing M365 data?
• Are third-party apps or legacy permissions posing risks?

Designed for Lean Security Teams

Unlike traditional cloud tools that demand large SOCs, CSX is optimised for lean teams. With a guided onboarding experience and real-time insights, organisations can get up and running in minutes.

“We had an employee leave with access to shared folders. Weeks later, we found out sensitive data was still accessible,” shared an SME IT head. “CSX would have flagged the issue immediately.”
