Siber Group - Information Security Is What We Do

What We See

Passive reconnaissance — blocklist reputation, open ports, services, and known vulnerabilities from public intelligence sources.

Your Public IP

Check Domain Name

Run all 9 security scans on any domain — DNS, WHOIS, SSL, headers, subdomains, email security, exposure, credentials, and heatmap.

Why Use Our Tools

Understand Your Attack Surface

Before attackers target your organisation, they gather information about your infrastructure. Our tools let you see what they see — DNS records, open ports, SSL configurations, and security headers — so you can fix weaknesses before they're exploited.

Some tools are freely available, while advanced scanning capabilities require a SiberGroup account. All tools are built with privacy in mind — we don't store your scan results.
