One of the most common questions organisations ask when planning a security assessment is whether penetration testing should be performed against a staging environment or a live production system. At first glance, staging appears to be the safer option. It provides an environment where testing can be conducted without affecting real users, customer data, or operational services.

For organisations considering a penetration test, one of the first questions is often how much it will cost. While this is a reasonable question, the answer is usually not so straightforward. Like many technology products and services, penetration testing is not a commodity. The scope, complexity, and objectives of each assessment can vary which means pricing can vary just as widely.

In May 2026, Redis disclosed a high severity memory safety vulnerability tracked as CVE-2026-23479.
