Free 1-Minute Website Check for the Age of AI Hacking: Security, SEO and AI Visibility
securitywebdevseoai
TL;DR
Attacks are moving from people to automated AI agents, and the entry point is usually the same: an internet-facing site with weak security hygiene. The first defensive step, knowing what your site looks like from the outside, takes about a minute. FreeWeb Security SCAN checks security, SEO basics and AI visibility from a single URL. It is free, read-only, and needs no install, login or credit card.
Why does website hygiene matter more in 2026?
In 2026, the open-source AI penetration agent ARTEX was used in real attacks reported worldwide, including campaigns against thousands of Microsoft 365 accounts and breaches of e-commerce order databases. The common thread was not exotic zero-days. It was exposed, unpatched systems and sloppy web security hygiene. When attacks are automated, defense has to start with an automated look at your own surface.
What do the terms in a security report actually mean?
- Security response headers: the locks and cameras on your front door. Without them you are open for business with the door wide open.
- HTTPS: a sealed envelope versus a postcard anyone can read.
- SPF, DKIM, DMARC: the ID card for email sent in your company's name. Without them, someone can impersonate your domain in phishing mail.
- TLS certificate validity: your business license. Once it expires, visitors see a "dangerous site" warning and leave.
- Mixed content: a small hole in a strong safe, where an HTTPS page loads HTTP resources.
- AI visibility (GEO): whether AI assistants can get inside your site at all before they can recommend you.
Why is AI visibility suddenly important?
More people now ask ChatGPT, Claude or Perplexity and take the answer directly. Which companies those assistants cite has become a new visibility race. Many sites block AI crawlers without knowing it: robots.txt says "welcome", while a firewall or CDN rule silently rejects specific bots. The assistant cannot read you, so it cites a competitor instead.
What does the free check cover?
Enter a URL and, in roughly 10 to 25 seconds, you get a read-only report with no attack traffic and no load on your server, along three axes:
- Security: how many security headers are on, whether HTTPS and the certificate are healthy, and whether sensitive configuration files are accidentally public.
- SEO foundation: titles, descriptions and structured data that search visibility depends on.
- AI visibility (GEO): whether Google, Bing, Naver and 9 AI crawlers such as GPTBot, ClaudeBot and PerplexityBot can actually reach your site.
Each item is marked pass, needs work or fail, ordered by urgency, and explained in plain language.
What does the deeper report add?
If you sign up with your organization's domain email and verify ownership, the scan expands from the home page to the whole site:
- Email security in depth: SPF strength, DKIM signing, whether DMARC only monitors or actually rejects, plus BIMI and MTA-STS.
- Domain security: DNSSEC and CAA, which protect the domain itself from tampering.
- Site-wide consistency: HTTPS and headers on every page, integrity seals on third-party scripts, and exposed patterns that look like sensitive data.
Everything stays read-only. Scanning someone else's site in depth is not allowed, and real penetration testing only happens with the owner's written permission.
How should I act on the results?
- Fix red (high) items first, such as exposed sensitive files or a certificate about to expire.
- Then work through yellow (needs work) items, such as missing headers or email spoofing protection.
- Remember that a non-intrusive scan sees the external surface. Whether something is actually exploitable (SQL injection, authentication bypass) and how an AI agent would chain it requires a permission-based deep assessment.
FAQ
Is it really free? Yes. No install, no login, no credit card. Just a URL.
Will the scan affect my site? No. It only reads public pages, so there is no attack traffic or load.
Which AI crawlers are checked? Nine AI crawlers including GPTBot, ClaudeBot and PerplexityBot, plus Google, Bing and Naver.
Can I scan a site I do not own? Only the public surface of the home page. Site-wide scans unlock after domain ownership is verified.
