Digital security provider Cybereason is poised to announce Wednesday that it received a $100 million investment from SoftBank Corp. of Japan, an infusion that more than doubles the Boston company’s funding and gives it new prominence among the region’s technology startups.
Cybereason, which helps clients quickly identify, defend, and analyze attacks on their computer systems, said it has now raised a total of $189 million since being founded in 2012.
Chief executive and cofounder Lior Div said the company plans to use the money for business development, to improve its technology, and to build its workforce. Cybereason has about 300 employees, 110 of whom are in Boston.
He said the company is seeking to differentiate itself in the burgeoning cybersecurity field by using software to rapidly determine the scope of hacking attacks, looking across clients’ systems to find evidence of how far the danger has spread.
“We’re actually making it accessible to people who are not experts,’’ Div said in an interview. “This is a huge difference between us and the others companies out there.’’
The big investment furthers the relationship between Cybereason and SoftBank, which has been one of the company’s largest clients and has been a partner in distributing its services in Japan.
SoftBank is now Cybereason’s top investor. Previous investors in Cybereason include CRV, Spark Capital, and Lockheed Martin.
The companies did not reveal the valuation on which this week’s investment was based.
“Cybereason’s products are truly amazing. SoftBank tested a number of cybersecurity products from all over the world, but Cybereason’s products are by far better than those of their competitors,’’ Ken Miyauchi, president and CEO of SoftBank Corp., said in a statement.
Izhar Armony, general partner at CRV, said in an interview that the investment by SoftBank is particularly encouraging given the existing relationship with Cybereason.
“Customers know better than investors, so if a big customer decides to become a large investor, it’s a very strong validation of the approach, the technology, and the people,’’ he said.
The investment is the second significant move announced in the region recently by SoftBank. This month, SoftBank Group, the parent company of SoftBank Corp., acquired Boston Dynamics from Alphabet Inc., the parent company of Google. Waltham-based Boston Dynamics makes walking robots that have drawn broad attention in online videos.
