Online Scanner is a free tool for detecting open ports on your device. It automatically detects IP-address and scans your device, identifying open and vulnerable ports through which hackers, viruses and Trojans can break into your system.
What is a port scanner?
A port scanner is a tool that checks which ports are open on a server or device, helping identify potential security vulnerabilities.
Security Implications
Open ports can be entry points for attackers, so it's important to know which ports are accessible from the internet. Regular port scanning helps identify potential security vulnerabilities.
Network Visibility
Port scanning provides visibility into your network's exposure, helping you understand which services are accessible and potentially vulnerable to attacks.
Legal Considerations
Port scanning without permission may be illegal in some jurisdictions. Only scan IP addresses or domains that you own or have explicit permission to scan.
How to secure your ports
Protect your system by securing open ports and minimizing your attack surface.
Use a Firewall
Configure your firewall to block unnecessary ports and only allow traffic to services that need to be publicly accessible.
Regular Audits
Perform regular port scans to identify newly opened ports and ensure your security measures remain effective.
