MeetingTV says Koi Security wrongly linked the company to cyber activity involving stolen online meeting data.

MeetingTV added Palo Alto Networks to a lawsuit over a Koi Security report that the videoconferencing company says wrongly connected it to malicious cyber activity.

The case was filed on March 18 in the U.S. District Court for the Southern District of California. MeetingTV originally sued Koi Security Inc., Koi Security Ltd., and several Koi executives. It added Palo Alto Networks as a defendant in an amended complaint filed May 13, about one month after Palo Alto Networks completed its acquisition of Koi.

The dispute centers on a December 2025 Koi report alleging that browser extensions were stealing online meeting information from millions of users. Koi said the extensions collected meeting links, login details, and other information from video meetings across major platforms.

MeetingTV says Koi wrongly tied MeetingTV domains to that activity. In its amended complaint, the company says the report made MeetingTV appear to be part of a cyber operation and harmed its business.

The lawsuit includes claims for defamation, trade libel, and related claims over alleged business harm. Justia lists the case as an assault, libel, and slander matter, with MeetingTV demanding a jury trial.

In the latest court order issued on June 23, U.S. District Judge Anthony J. Battaglia denied MeetingTV’s request to serve Koi Security Ltd. and several individual defendants by email, as the company is headquartered overseas.

Koi Security previously moved to dismiss MeetingTV’s original complaint. That motion was denied without prejudice after MeetingTV filed the amended complaint. The case remains active.
