YL Ventures, an active venture capital firm that focuses on early-stage cybersecurity startups, has closed a new $400 million fund and announced plans to ramp up investments in Israel’s security technology sector.

The Tel Aviv-based firm, which counts red-hot companies like Axonius and Orca Security among its portfolio, said the closing of its fifth fund brings the total capital under management to $800 million.

The firm said the plan is to use the new capital to support Israeli security startup founders “from inception through every critical stage” of building and positioning a company to solve pressing security problems.
