Siga OT Solutions is an Israeli cybersecurity startup that assists organizations in protecting their operations by monitoring critical industrial assets' raw electric signals. It has raised $8.1 Million in Series B funding.Sigas SigaGuard claims its technology is used by Israel's critical water facilities as well as the New York Power Authority. It uses machine learning and predictive analytics to listen for Level 0 signals, rather than monitoring the operational networks. These typically consist of sensors and components that receive electrical signals. They are not data packets or protocols that hackers can manipulate.The company monitors Level 0, which Siga refers to as the highest and most reliable level process data in any operational environment, and can detect cyberattacks against the most sensitive and vulnerable assets of national infrastructures. It claims this ensures operational resilience even when hackers manage to manipulate the logic of industrial control systems (ICS) controllers.Amir Samoiloff is co-founder and CEO at Siga. He says that Level 0 is rapidly becoming the key axis for resilience and integrity in critical national infrastructures around the world and that securing this level in control systems will be a major component in the future.PureTerra Ventures led the company's most recent round of funding. This investment included investments from Israeli venture funds SIBF, Moore Capital and Phoenix Contact. The latest round comes amid an increase in cyberattacks against infrastructure. Three cyberattacks on Israel's water infrastructure were reported in 2020. These were followed by an attack against the water system in Oldsmar, Florida by hackers who temporarily increased the sodium hydroxide level.Three years ago, the startup raised $3.5 million in Series B funding. The $8.1 million investment comes three years later. The company stated that it will use the funds to increase its sales and international strategic collaborations, with a particular focus on North America and Europe.Continue reading:
