alienvault.com website review

14 images could be 6.0 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 4.5 s faster on a phone.

57 files are served with short cache lifetimes, so returning visitors download them again (1.4 MB).

About 954 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.7 s faster on a phone.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.5 s.

About 253 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.2 s faster on a phone.

Your mobile performance score is 47 (desktop: 42). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.1 s on main-thread work while loading, 3.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Quantum Metric and Adobe Tag Manager and others), adding 1.4 MB and 1.2 s of main-thread time.

171 KiB could be saved by minifying JavaScript.

Google Tag Manager costs a phone 358 ms of main-thread work and 464 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

The page has 1,803 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Cludo costs a phone 66 ms of main-thread work and 308 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

18 long tasks block the main thread while loading, the longest for 214 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 36 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Real visitors wait 4.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Your largest element takes 13.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 47.8 s. Good is under 3.8 s.

Visually, the page fills in at 12.8 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.2 s on a phone. Good is under 1.8 s.

Real visitors wait 279 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 200 ms to 280 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 3.4 s to 4.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.5 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.6 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 513 ms in total while the page loads. Good is under 200 ms.

11 images have no width and height attributes, so the layout jumps as each one loads.

Your homepage downloads 10.1 MB in 302 requests on a phone: images 6.5 MB (94), scripts 2.7 MB (93) and other files 438 KiB (93). Under 2 MB keeps phones on slow connections fast.

6 images weigh 4.5 MB together. On a phone connection a single image that size takes seconds.

4 images are downloaded at several times the size a phone draws them, for example 4232702-base-hero-cybersecurity-mbl-retina.jpg at 1,526 px wide, shown at 390 px. Resized copies would save about 1.0 MB.

14 images (6.4 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

13 images further down the page (5.5 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 2.87 g of CO₂e: 344.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid values: 12 elements on the page fail this check, rated critical by axe-core.

1 button has no accessible name, so screen readers announce just “button”.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

The skip-link target should exist and be focusable: 1 element on the page fails this check, rated moderate by axe-core.

6 visible links have no text or label, so screen readers cannot say where they go.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

Your meta description is 167 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

7 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 158 pages on alienvault.com and 33 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

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.

We fetched 15 pages linked from your homepage (of 108 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://id.rlcdn.com/464526.gif.

5 of 13 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

6 errors were logged to the browser console while the page loaded, for example “Access to fetch at 'https://ipapi.co/country/' from origin 'https://www.business.att.com' has been blocked by CORS poli…”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

Chrome logged issues while loading the page (“Mixed content”).

Large scripts ship without source maps.

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

HSTS is set, but max-age is 1 days; one year is the recommended minimum.

Opening https://alienvault.com goes through 2 redirects before the homepage loads.

3 links go through two or more redirects, for example https://www.att.com/buy/phones/?smb=true.

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.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

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

att.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

att.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

Your longest form asks for 8 fields (0 required). Every extra field lowers completion.

The homepage carries about 942 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.

Before a visitor clicks anything, the page loads Amazon Ads, Google Ads, Google Tag Manager, LinkedIn Insight and Microsoft Ads and 3 mores (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 38 cookies, 4 of them by other companies (measured from a US location before any click).

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 47 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
