Software Vulnerability Tracker/Scanner

Hello all! My company decided that now they want to be on a cybersecurity kick and want to up their game. I came up with an idea to install a client or a remote software scanner to check for open CVEs and vulnerabilities based on their versions. Is there any software that already exists for that? We have THOUSANDS of computers on our network, and some aren’t allowed to reach outside the intranet.
