Zscaler is a multi-billion dollar company, and the comment you replied to basically describes their primary product. Cloudflare now has a Secure Web Gateway product. So does VMware, and Cisco, and just about any networking/security vendor who is trying to make a play in the "SASE" space. Hate to say it, but invisible TLS-intercepting proxies are more widely used today than they were in the 90s.
