skyboxsecurity.com website review

About 420 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.5 s faster on a phone.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.1 s.

Your mobile performance score is 45. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, Optanon and chilipiper.com and others), adding 753 KiB and 800 ms of main-thread time.

Google Tag Manager costs a phone 671 ms of main-thread work and 535 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.

10 files are served with short cache lifetimes, so returning visitors download them again (147 KiB).

9 long tasks block the main thread while loading, the longest for 266 ms. During a long task the page ignores taps.

A phone's processor spends 2.1 s on main-thread work while loading, 1.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 37 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

Polyfills for old browsers add 20 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

1 image could be 9 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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.

Your largest element takes 10.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Tufin Welcomes Skybox Customers – Your Path to Better Netwo…”.

The first text or image appears after 4.1 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 10.1 s. Good is under 3.8 s.

Visually, the page fills in at 6.3 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 680 ms in total while the page loads. Good is under 200 ms.

Real visitors see the first content after 1.9 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 169 ms to 154 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.32 g of CO₂e: 39.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 buttons have no accessible name, so screen readers announce just “button”.

ARIA attributes must conform to valid names: 1 element on the page fails this check, rated critical by axe-core.

1 dropdown has no label.

5 tap targets are too small or too close together to hit reliably with a finger.

4 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

ARIA dialog and alertdialog nodes should have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

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

3 form fields have no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h2 → 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 78 characters, so Google will cut it off around 60: “Tufin Welcomes Skybox Customers – Your Path to Better Network Security | Tufin”.

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

The homepage links to 229 pages on skyboxsecurity.com and 23 external pages.

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.

/contact-us, /support, /why-tufin and /products/tos-discovery have no meta description, so Google writes the search snippet from whatever text it finds.

/tufinai has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 102 found) and read each the way a search engine does.

4 of 11 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://lp.tufin.com/js/forms2/css/forms2.css' from origin 'https://www.tufin.com' has bee…”.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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.

1 link go through two or more redirects, for example https://extensions.tufin.com/.

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.

tufin.com is registered until Nov 2026. If it lapses, the site and its email stop working and someone else can buy the name. Renew it, and turn on auto-renew.

tufin.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 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 1,067 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 Google Ads, Google Analytics and Google Tag Manager (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 8 cookies (measured from a US location before any click).

Loading the homepage contacts 11 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
