Detailed Review
Patchstack's RapidMitigate applies targeted mitigation rules to block exploitation of known vulnerabilities without changing site code. The vendor says it holds 12,000 unique mitigation rules and claims it prevents up to 74 percent more vulnerabilities from being exploited than leading web application firewalls, which is a vendor statement.

Virtual patching, not a general WAF
Patchstack covers vulnerabilities in WordPress core, plugins and themes and in open-source code more widely. It does not replace a general-purpose reverse proxy WAF for custom applications, and the vendor positions it as an addition to hosting defenses.
Plans
The Developer plan is 69 dollars a month billed annually (828 dollars a year) with three seats, a first month free, and extra sites in packs of five at 12.50 dollars a month. Enterprise and Web host plans are custom billing.
Hosting partners
The vendor sells to web hosts with a plug-and-play security widget and rollout support, and lists a large set of hosting partners.
Limitations to Consider
Patchstack targets known, catalogued vulnerabilities in open-source software, so it does not inspect traffic for custom application logic the way a full WAF does. Prices are in USD. The pages checked do not state the data location of the service.
Who Should Use Patchstack
WordPress agencies, hosts and maintainers who want known plugin vulnerabilities mitigated quickly.
