Why Open Port Security Matters
Billions Indexed Daily
Shodan and Censys index billions of exposed services daily. Automated bots continuously scan for open database ports, admin panels, and misconfigured services.
Shadow Services
The most dangerous ports are the ones left open accidentally — dev databases on default ports, forgotten debug endpoints, legacy services nobody remembers installing.
60-Second Detection
AI QA Monkey checks the most targeted ports, identifies running services, performs version fingerprinting for known CVEs, and provides one-click firewall rules.
Sample Scan Results
Here's what a typical port scan reveals — real findings from anonymized scans.
What We Scan
TCP Port Scanning
Scan the top 30 most targeted TCP ports including SSH (22), FTP (21), MySQL (3306), RDP (3389), PostgreSQL (5432), and more.
Service Fingerprinting
Identify the exact software and version running on each open port. Detect outdated versions with known CVEs that attackers actively exploit.
Database Exposure
Detect publicly accessible MongoDB (27017), Redis (6379), Elasticsearch (9200), Memcached (11211), and CouchDB (5984) instances.
Admin Panel Detection
Find exposed admin interfaces on common ports — phpMyAdmin, cPanel, Webmin, Jenkins, and Kubernetes dashboards accessible without VPN.
Firewall Analysis
Detect misconfigured firewalls, missing security groups, and overly permissive rules that expose internal services to the public internet.
SSL & Security Headers
Certificate validation, HSTS, CSP, and critical header analysis alongside port scanning for comprehensive security posture.
Sensitive File Leaks
Detect exposed .env, .git, backup files, and configuration files alongside open ports for full attack surface coverage.
CORS & API Discovery
Detect CORS misconfigurations and exposed API endpoints running on non-standard ports that bypass your main application firewall.
Attack Surface Mapping
Visual network graph of your full external attack surface — all open ports, services, subdomains, and SSL status in one interactive map.
One-Click Copy Fix
Every open port finding includes firewall rules (iptables, ufw, AWS Security Groups) you can copy and apply immediately, plus AI Fix Prompts.
DNS & Reputation
SPF/DMARC records, subdomain discovery, and blacklist monitoring alongside port scanning for complete domain intelligence.

Common Questions
What are open ports and why are they dangerous?
Open ports are network endpoints that accept incoming connections. While some ports must be open for services to function (port 80 for HTTP, 443 for HTTPS), unnecessary open ports expose services to the internet that attackers can exploit. Common risky ports include SSH (22), FTP (21), MySQL (3306), RDP (3389), and MongoDB (27017). Each open port is a potential entry point for brute-force attacks, data exfiltration, and remote code execution.
Which ports does the scanner check?
The free scan covers the top 30 most targeted ports: FTP (21), SSH (22), Telnet (23), SMTP (25), DNS (53), HTTP (80), POP3 (110), IMAP (143), HTTPS (443), SMTPS (465), Submission (587), IMAPS (993), POP3S (995), MySQL (3306), RDP (3389), PostgreSQL (5432), MongoDB (27017), Redis (6379), Elasticsearch (9200), and Memcached (11211). The premium scan covers all 65,535 ports.
How do I close open ports on my server?
To close unnecessary open ports: 1) Identify the service running on the port using netstat or ss. 2) Stop the service if it's not needed. 3) Configure your firewall (iptables, ufw, or cloud security groups) to block incoming connections. 4) For services that must run, restrict access to specific IP addresses. AI QA Monkey provides one-click copy fix commands for each detected open port.
Is port scanning legal?
Port scanning your own servers and domains is completely legal and is a standard security practice recommended by NIST, ISO 27001, and PCI DSS. You should only scan domains and IP addresses that you own or have explicit written authorization to test. AI QA Monkey is designed for legitimate security auditing of your own infrastructure.

Attackers scan your site every day. Watch what they find — and how one report shuts them out.
A real site, a real scan: 27 hidden issues exposed in 60 seconds — exposed credentials, open database ports, spoofable email — then fixed the same day with the copy-paste code inside the $29 report, verified with free re-scans until the score climbs from 67 to 90, and sealed with a Verified Secure badge your visitors can see. The same recon a consultant bills $1,500+ for.
