SysCore Tools
Website vulnerability scans, DNS, SSL, mail auth and SEO checks — with the same results over a public API.

Website vulnerability scan
Paste a URL — we run a curated surface scan for missing security headers, TLS problems and common exposures. Results are scored and available via API. Not a penetration test.
Quick start
Full catalogVulnerability & Exposure Scan
Serious automated check for leaked .git/.env/configs, tokens, backups, dumps and known web exposures (Nuclei + path probes).
Port Scan (nmap)
Classic nmap recon: discover open TCP ports and risky services (SSH, RDP, MySQL, Redis, Mongo…).
Site Performance (CWV)
Lighthouse performance score + Core Web Vitals style metrics (LCP, CLS, TBT, FCP) and top opportunities.
SSL / TLS Check
Verify the HTTPS certificate: expiry, issuer, and whether it matches your hostname.
Security Headers
Audit the HTTP response headers that harden browsers against XSS, clickjacking and mixed content.
SPF / DKIM / DMARC
Check whether your domain publishes the DNS records that stop spoofing and improve inbox delivery.
All tools
Every check is available in the UI and as /api/v1/tools/{id}/runs.
Network
DNS Lookup
See which servers answer for your domain — web, mail, nameservers and TXT records in one place.
Redirect Chain
Follow every hop from a URL to the final page — useful for http→https and www cleanup.
Domain RDAP / WHOIS
Lookup domain registration status, nameservers and expiry date via RDAP.
Security
