When each one fits
Pi-hole is enough when a technical operator runs a very small network, wants full manual control, and does not need malware threat intelligence, support or per-subscriber monetization. It is free and highly configurable, but it is a DIY ad blocker, not a managed security service.
Cisco Umbrella fits enterprises securing their own employees across locations. It is a mature cloud security platform, but it is priced per seat and is not built for an ISP to resell protection to thousands of subscribers.
FlashStart suits ISPs and MSPs that want fast, cloud-based content filtering with minimal setup. It ranks well on DNS resolution speed, but it runs cloud-only and does not publish an on-premises resolver or a subscriber white-label and revenue-share model.
Whalebone Peacemaker fits ISPs that want to run protection inside their own network (on-premises resolver or cloud), see traffic at the local IP level, meet national blocking requirements, and sell security and parental control to subscribers as a revenue stream.

Yes. With a white-label tier such as Peacemaker Profit, an ISP can sell security and parental control to subscribers as a paid add-on, with a self-care portal and revenue sharing.
Pi-hole is a free, self-hosted ad and tracker blocker for small networks. It has no malware threat intelligence, no commercial support and no per-subscriber management, so it is not suited to running security at ISP scale.
