Description: External verification is a method used to monitor systems or services that are outside the internal infrastructure of an organization, using various tools. This approach allows system and network administrators to gather information about the status and performance of external services, such as web servers, databases, or cloud applications. External verification is performed by collecting data through network protocols such as HTTP, ICMP, or SNMP, enabling the detection of availability, latency, or performance issues. One of the main features of this method is its ability to provide an objective view of the service status, as it is conducted from an external perspective, which can help identify problems that are not evident from within the network. Additionally, external verification is crucial for ensuring that critical services are operational and meet service level agreements (SLAs), which in turn contributes to customer satisfaction and business continuity. In an increasingly interconnected environment, where companies rely on multiple external services, external verification has become an essential practice for proactive management of technological infrastructure.
