Pen test vendor rotation: do you need to change annually?. You might have heard about the practice of pen test vendor rotation, or even tried it yourself. This is where organizations change their pen test providers annually to avoid complacency and maintain an objective perspective on their security posture. Pen testing isn’t an exact science – you can never be totally sure all vulnerabilities have been found. Different vendors have different skillsets and areas of expertise, so it stands to reason that rotating between them will catch more issues in the long run. However, is this strategy truly effective? We’ll give you the facts on whether you really need to change pen test providers every year, and consider how continuous testing solutions, like those offered in the Penetration Testing as a Service (PTaaS) model, present an effective alternative. The argument for pen testing vendor rotation First things first, changing pen test providers annually isn't a hard and fast rule set by regulatory bodies. It's more of a best practice that some organizations choose to follow. The idea is that bringing in a new team each year might help uncover vulnerabilities that a previous tester missed. The arguments for pen testing vendor rotation include:   Drawbacks of rotating pen testing providers There are also arguments against regularly rotating pen test vendors. Some experts believe that building a long-term relationship with a single trusted vendor can actually be more beneficial. Some potential problems with rotating your pen testers include: PTaaS: A sustainable alternative Rotating vendors is one way to ensure a fresh perspective and prevent complacency in pen testing. However, constantly onboarding new vendors can also be time-consuming and resource intensive. This is where PTaaS comes in as a sustainable alternative. PTaaS allows organizations to outsource their pen testing needs to a single provider that manages the entire process from start to finish. This eliminates the need to constantly onboard and manage multiple vendors, saving time and resources. PTaaS providers also typically have a standardized approach to testing, making it easier to compare and analyze results. Another benefit of PTaaS is that it offers consistent and more frequent testing timelines for enhanced security. This means that organizations can schedule regular pen tests, as opposed to annual ones, without worrying about coordinating different schedules. Finally, PTaaS vendors typically have a larger pool of testers, who bring a diverse set of skills and perspectives to the testing process. The testing can be more in-depth and fully customized to your needs. What’s the verdict? While rotating pen test providers annually may bring some benefits, a continuous and comprehensive testing approach can offer you a more effective solution. The best PTaaS solutions offer a large pool of testers, consistent methodologies, real-time insights, and scalability.
