2crsi.co.uk website review

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

About 196 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 900 ms faster on a phone.

Your mobile performance score is 80. Pages that score under 90 lose visitors before the first paint.

About 743 KiB of JavaScript is downloaded but never used on this page.

5 long tasks block the main thread while loading, the longest for 665 ms. During a long task the page ignores taps.

4 images could be 125 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

2 third-party services load with your homepage (odoo.com and Google Fonts), adding 153 KiB and 13 ms of main-thread time.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

15 KiB could be saved by minifying CSS.

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.

2 files are served with short cache lifetimes, so returning visitors download them again (2 KiB).

The page becomes fully interactive after 14.4 s. Good is under 3.8 s.

Visually, the page fills in at 5.5 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.7 s on a phone. Good is under 1.8 s.

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

Scripts block taps and scrolling for 336 ms in total while the page loads. Good is under 200 ms.

Your largest element takes 2.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Edge computing systems built for the real world”. Most of its time is element render delay (1.7 s).

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.

Your homepage downloads 2.5 MB in 32 requests on a phone: scripts 1.3 MB (5), images 778 KiB (14) and fonts 234 KiB (6). Under 2 MB keeps phones on slow connections fast.

5 images further down the page (178 KiB) 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 0.71 g of CO₂e: 85.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Headings skip levels (h3 → h5), which makes the page harder to scan with a screen reader.

Structured data found (OnlineStore) but with 1 problem, for example “OnlineStore: sameAs is an empty list”.

The homepage links to 45 pages on 2crsi.co.uk and 7 external pages.

Your Organization JSON-LD is missing 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.

/products/tranquil-it has no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /tranquil-defence, whose canonical is /tranquil-resilience. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 24 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME”.

Large scripts ship without source maps.

1 link to other sites is dead, for example https://x.com/Tranquil_IT_GB (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.

1 link go through two or more redirects, for example https://investors.2crsi.com/en/welcome-2/.

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.

2crsiedge.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.

2crsiedge.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.

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

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 1,564 words of visible text.

DMARC is set to p=none, so mail pretending to be 2crsi.co.uk is still delivered. Reports are on, so moving to quarantine is the next step.

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.

Opening the homepage sets 3 cookies (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 3 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
