Alphabet Inc. is in talks to purchase cloud-security company Wiz Inc. for $33 billion, restarting discussions that were called off last summer after extended negotiations, according to people familiar with the matter.

Alphabet, Google's parent company, announces its largest acquisition ever, buying cybersecurity firm Wiz for $32 billion. This move intensifies its cloud-computing competition against Amazon and Microsoft.

The all-cash deal is set to boost Alphabet’s profile in the cloud computing market, a space currently led by Amazon and Microsoft.

With satellite internet facing new competition, Taara’s laser-based technology offers a different path to global connectivity.

Rather than use orbiting satellites, Taara plans to deliver fiber-like internet through the air using ground-based equipment that beams light.

Taara, a spin-out company to emerge from the “Moonshot” unit belonging to Google’s corporate parent Alphabet, says it will use new venture capital funding to scale up its efforts to offer high-speed connectivity using free-space optics.
