We have seen significant reduction of threats, especially those that were detected via web scanning services such as Sucuri Firewall or Web Application firewall like OWASP ZAP (Zed Attack Proxy).
Our organization is heavily dependent from external sources to scan for vulnerabilities; using this tool we can reduce these costs significantly by having it done automatically without requiring additional resources/employees dedicated only doing so work. It does not provide any kind support beyond normal tech issues which I would highly recommend considering before jumping into buying an expensive product with no free trial period included if there's nothing within their offerings to make them worth paying money upfront.
