BiomX Inc. (NYSE American: PHGE) is now Tessera Defense and Homeland Security Inc. (NYSE American: HLSQ).
Our Company
Tessera is a physical-security technology company building an Autonomous Physical Security Platform for homeland security and critical infrastructure.
We believe modern physical security works best when intelligence, sensing and response are connected rather than managed as separate systems. By bringing these capabilities together through one software-led platform, Tessera enables security teams to understand threats earlier, make better decisions and coordinate action faster.
We envision a future where critical infrastructure and national assets are inherently resilient, protected by intelligent, autonomous systems that act as a seamless, unified shield.
By bridging the gap between advanced sensing and real-time response, we aim to set the global standard for high-consequence security, ensuring that the organizations safeguarding our society are always one step ahead of the evolving risks of tomorrow.
Bring your cameras, sensors, intelligence and access systems into one platform that understands
what’s happening and coordinates what happens next
We stay focused on helping customers protect people, infrastructure and institutions when the stakes are high
We maintain clarity and focus when events move fast for clear-headed operation and decision-making when the stakes are high

Threats, technologies and customer needs change. We build, test and improve with that reality in mind
