External vulnerability scanning tests your internet-facing systems and services from an attacker's perspective, without requiring network access or credentials. It identifies vulnerabilities that can be exploited from the internet, such as exposed services, outdated software, misconfigured firewalls, and unpatched systems.

Cloud environments are constantly changing with new instances, services, and configurations being deployed. External scanning helps you maintain visibility of your cloud attack surface, ensuring that new assets are automatically discovered and scanned for vulnerabilities. This is especially critical in cloud environments where assets can be created and exposed to the internet quickly.

Vullify integrates with AWS, Azure, and Google Cloud Platform to automatically discover new external IP addresses, hostnames, and services as they are added to your cloud accounts. You can configure automatic scanning of new assets and set rules to control what gets imported and scanned.

External scanning detects a wide range of vulnerabilities including exposed services and ports, outdated software versions, missing security patches, misconfigured cloud services, exposed databases, insecure API endpoints, and weak encryption configurations. It also identifies potential attack vectors that could be exploited by attackers.

External scanning tests your systems from the internet without authentication, simulating how an attacker would approach your infrastructure. Internal scanning uses authenticated access to test systems from within your network. Both are essential: external scanning finds vulnerabilities accessible to attackers, while internal scanning finds issues that exist after a breach.

Yes, Vullify's external scanning can identify cloud misconfigurations such as publicly accessible S3 buckets, exposed databases, open security groups, and improperly configured cloud services. These misconfigurations are a leading cause of cloud security breaches.

We recommend continuous external scanning. Your attack surface changes constantly as new services are deployed, IP addresses change, and configurations are modified. Continuous scanning ensures that new vulnerabilities are detected immediately, reducing your window of exposure to potential attacks.

Yes, Vullify supports scanning across multiple cloud providers simultaneously. You can connect AWS, Azure, and Google Cloud Platform accounts, and Vullify will automatically discover and scan assets across all your cloud environments from a single unified dashboard.

When Vullify detects a critical vulnerability, it immediately sends alerts through your configured notification channels (email, Slack, Teams, etc.). Critical findings are prioritized in the dashboard with detailed information about the vulnerability, its potential impact, and step-by-step remediation guidance. You can also configure custom alerting rules based on severity and asset criticality.
