What gets checked

Check seven parts of the public site.

Review security, search, performance, accessibility, legal signals, runtime, and infrastructure in one connected scan.

Interactive view of seven website areas checked by SlaySlop

Find weak headers, exposed secrets, known vulnerabilities, and public backend misconfigurations.

What you receive

See why each finding matters.

Each finding shows its impact, the evidence behind it, and whether the next scan confirms the fix.

Interactive report view with findings, evidence, and rescan progress

Start with the issues that create the greatest risk.

Domain insights

See the public signals around the page.

DNS, TLS, headers, mail, tech stack, and related checks land beside the ranked findings so infrastructure context is not a separate audit.

Security posture

TLS certificates, HTTP security headers, WAF signals, HSTS, and public block-list reputation.

Server and DNS

DNS records, DNSSEC, WHOIS, mail configuration, redirects, ports, and server location.

Content surface

Tech stack fingerprints, robots.txt, sitemaps, cookies, social tags, and linked pages.

Post-launch monitoring

Keep watching after launch.

Run uptime probes around the clock, schedule deeper rescans, and send clear alerts when the site changes.
