codean.io website review

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

7 files are served with short cache lifetimes, so returning visitors download them again (136 KiB).

About 14 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 130 ms faster on a phone.

1 third-party service load with your homepage (Cloudflare), adding 10 KiB and 10 ms of main-thread time.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

By the Sustainable Web Design model, a visit to your homepage emits about 0.06 g of CO₂e: 7.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Some lists contain elements other than list items, which screen readers announce wrongly.

All page content should be contained by landmarks: 10 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

Headings should not be empty: 3 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h2 → h4 and h1 → h4), which makes the page harder to scan with a screen reader.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 18 characters: “Home - Codean Labs”. Between 30 and 65 characters leaves room to say what you do and for whom.

There are 2 <h1> headlines (“We find critical vulnerabilities before hackers e…” and “Let’s talk. One short call to explore if our appr…”). One clear main headline is easier for people and search engines.

No Open Graph image (also missing: og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 14 pages on codean.io and 8 external pages.

Your Organization JSON-LD is missing url, logo, sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

/pricing, /category/research, /about and /services-ctf have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 5 pages linked from your homepage and read each the way a search engine does.

6 of 10 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Cannot use import statement outside a module”.

1 link from your homepage to your own site is broken, for example https://codeanlabs.com/cdn-cgi/l/email-protection (404).

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

Social proof on the homepage: 3 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 650 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 1 host run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
