For Immediate Release

ATLANTA, GA, September 30, 2026 — The company today announced that it is rebranding as Mithryl Systems, a DBA of PhishCloud, Inc., reflecting an expanded focus on protecting the operational environments that power critical infrastructure. As part of the launch, Mithryl Systems is introducing Mithryl OT Managed Detection & Response (OT MDR), a purpose-built 24x7x365 managed security service for operational technology environments.

The transition builds on years of experience across OT cybersecurity, cyber fusion, detection engineering, incident response and critical infrastructure. That work reinforced a central lesson: industrial organizations need security capabilities that understand how cyber events affect production, safety, availability, engineering, compliance and business continuity.

Mithryl Systems brings that experience together under a broader operational cybersecurity strategy built around Unified Defense for Critical Systems.

“Mithryl Systems isn't a new beginning. It reflects what we have learned working with organizations responsible for critical operations. Cybersecurity has to understand the operation it is protecting. Mithryl brings a stronger focus to operational intelligence, OT security services and the outcomes that matter most to critical infrastructure.”

— Terry McCorkle, Chief Executive Officer, Mithryl Systems

Introducing Mithryl OT Managed Detection & Response

At the center of Mithryl's expanded OT strategy is Mithryl OT MDR. The service delivers around-the-clock monitoring, investigation, threat hunting, detection engineering and guided response for operational environments. Unlike MDR models designed primarily around enterprise IT assumptions, Mithryl OT MDR is built around the premise that security response must account for the operation itself.

A suspicious event on an engineering workstation, historian, jump server or other operationally important asset cannot be evaluated solely by asking whether activity is malicious. Analysts must also understand what the asset supports, what systems depend on it, whether production or safety could be affected, and whether a containment action could create additional operational risk.

Mithryl OT MDR includes:

  • 24x7x365 OT security operations
  • OT-specific detection, investigation and threat hunting
  • Detection engineering and optimization
  • Digital forensics and incident response
  • Operationally informed response recommendations
  • Operational Intelligence reporting
  • Vendor-neutral integration with existing OT and IT security technologies

From Security Telemetry to Operational Intelligence

Central to Mithryl Systems is Operational Intelligence, a decision-support model that connects cybersecurity information with asset context, engineering knowledge, operational consequence, compliance requirements and business priorities. The goal is to move beyond knowing that a security event occurred to understanding why it matters, what operations may be affected, what response options are available and what decisions need to be made.

This creates a common operating picture that security, engineering, operations, compliance and executive leadership can use to make better decisions.

“Critical infrastructure organizations don't ultimately measure cybersecurity success by how many alerts they generate. They measure it by whether they can continue operating safely and reliably. Operational Intelligence connects what security sees with what the operation needs to know.”

— Terry McCorkle, Chief Executive Officer, Mithryl Systems

A Broader OT Cybersecurity Portfolio

OT MDR is the flagship managed service within a broader Mithryl portfolio designed to improve detection capability, strengthen incident readiness and increase operational resilience. Services include OT Detection Engineering, OT Digital Forensics, OT Incident Response, OT Threat Hunting, OT Red Team Assessments, OT Virtual CISO Services and OT Cyber Fusion Strategy Consulting.

Mithryl works with customers' existing OT and IT technologies rather than requiring wholesale replacement of security investments. The objective is to improve detection quality, correlate signals across environments, accelerate investigations and provide the operational context required for safer, more confident decisions.

Focused on Critical Infrastructure

Mithryl Systems serves organizations operating complex and critical environments across electric utilities, power generation, oil and gas, water and wastewater, manufacturing, transportation, chemical processing, mining, food and beverage, and other industrial sectors.

The rebrand does not abandon the company's broader cybersecurity heritage. Phish360 will continue addressing human-layer phishing risk, while Mithryl's expanding OT portfolio addresses the operational side of the connected attack surface.

Built for Connected IT and OT Risk

The transition to Mithryl Systems reflects the changing relationship between people, enterprise systems, engineering environments and physical operations. A compromised identity can become an OT access problem. A compromised vendor can become an engineering access problem. Ransomware can become a production problem. Remote access can become an operational incident.

Mithryl's operating approach emphasizes OT-first expertise, human-governed decision making, Operational Intelligence, vendor neutrality, unified understanding across IT and OT, measurable operational outcomes and operational resilience.

Availability

Mithryl OT Managed Detection & Response is available immediately throughout North America. Organizations can learn more about OT MDR and Mithryl's broader portfolio of OT Cyber Fusion Services at OT MDR and contact.
