What is an infrastructure scanner?
An infrastructure scanner continuously monitors the perimeter of your digital environment: it performs automated scans on everything visible from the internet. Think of websites, servers, IP addresses, and network ports. Catcher24 automatically checks these components for incorrect settings, expired certificates, and known vulnerabilities, and translates technical findings into understandable, concrete recommendations for you and your team.
After a scan, you can see at a glance in the dashboard which items require attention, what the priority is, and how you can resolve the issues. After implementing recommendations or after a new release, you can immediately schedule a (re)scan to verify that everything has been properly restored.
What's included with our infrastructure scanner?
Your infrastructure is constantly changing. Our Catcher24 scanner automatically performs scans and checks whether everything still complies with industry standards, best practices, and guidelines.

Perimeter check
Complete visibility of your digital surface.
Catcher24 maps all your public targets: domains, subdomains, IPs, and ports. You can immediately see which components are unnecessarily open or incorrectly configured, so you can take action before attackers do.

DNS check
Reliable communication
Many organizations are at risk because DNS records such as SPF, DKIM, and DMARC are not set up correctly. Catcher24 detects deviations and helps you prevent important emails from ending up in spam or being easily misused for spoofing.

SSL Check
Secure connections guaranteed
An expired certificate can directly cost you customers or even cause security incidents. Catcher24 monitors the validity and configuration of your SSL/TLS certificates and warns you well in advance, so you always offer secure and trusted connections.
