About Manhattan Fire Safety Corp
Manhattan Fire Safety Corp, also referred to as MFS or Manhattan Fire & Security, is a licensed fire alarm and security services firm operating in New York City. It provides design, installation, inspection, and maintenance of fire alarm and auxiliary radio coverage systems that must meet FDNY requirements. The firm also supplies IT communication systems, structured cabling, and security solutions to commercial and industrial clients.
Organizations in this sector routinely collect and store records related to building access, alarm configurations, client contracts, and employee credentials. A breach at such a firm can therefore touch both operational safety data and personal information.

Companies of this type commonly hold records such as client contact details, service agreements, employee information, and technical documentation for installed systems. Without a confirmed inventory, the presence of any specific category of personal or operational data remains unconfirmed.
Why it matters

For individuals, the main concerns are potential misuse of any personal identifiers or contact data that may have been stored in the affected files. The organization faces operational and reputational consequences from the public listing and the loss of internal material.

Verification status is shown where available.
