Which service is NOT typically offered by outsourced (third party) security providers?

Restoral services are typically associated with internal incident response and recovery processes rather than being a service that third-party security providers offer. While outsourced security providers do engage in various activities such as monitoring, vulnerability assessments, and incident response, restoral services are focused on the recovery of systems and data after a security incident, which usually requires a deep understanding of an organization's unique environment, assets, and configurations.

On the other hand, third-party security providers frequently offer special skill sets, such as expertise in specific security technologies or compliance frameworks. They also provide staff augmentation, supplying skilled personnel to complement an organization's existing security team, and can help with the offloading of routine daily tasks, such as monitoring security events and managing firewalls, allowing organizations to focus on more strategic security initiatives. These services enhance an organization's security posture and operational efficiency, which is why they are commonly provided by external security partners.
