Sept 24 (Reuters) - U.S.-Israeli cybersecurity startup

Wiz is exploring a potential sale of existing shares at a

valuation ranging from $15 billion to $20 billion, Bloomberg

News reported on Tuesday.

The company is talking about a transaction that would let

existing shareholders tender from $500 million to $700 million

of their holdings, the report added, citing people familiar with

the matter.

Earlier in July, Wiz ended talks with Google-parent Alphabet

on a proposed $23 billion deal, a valuation that

nearly doubled what the cybersecurity firm announced in May,

when it raised $1 billion in a private funding round.

Venture firms involved in the potential deal include G

Squared, Thrive Capital and Lightspeed Venture Partners, the

report also said.

The company and the venture firms did not immediately

respond to Reuters' requests for comment.

Wiz provides cloud-based cybersecurity solutions that help

companies identify and remove critical risks on cloud platforms,

powered by artificial intelligence.
