firstblox.com website review

59 files are served with short cache lifetimes, so returning visitors download them again (3.0 MB).

About 1.6 MB of JavaScript is downloaded but never used on this page.

Your mobile performance score is 81. Pages that score under 90 lose visitors before the first paint.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 800 ms.

6 long tasks block the main thread while loading, the longest for 250 ms. During a long task the page ignores taps.

A phone's processor spends 2.1 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 224 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 290 ms faster on a phone.

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

3 third-party services load with your homepage (Usercentrics CMP, Google Tag Manager and Google Analytics), adding 378 KiB and 148 ms of main-thread time.

Polyfills for old browsers add 43 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.

2 KiB could be saved by minifying CSS.

The page becomes fully interactive after 20.2 s. Good is under 3.8 s.

Visually, the page fills in at 8.1 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.6 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 245 ms in total while the page loads. Good is under 200 ms.

Your largest element takes 2.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “FIRSTBLOX helps teams understand their AWS security posture…”. Most of its time is element render delay (1.1 s).

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

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 3.6 MB in 77 requests on a phone: scripts 3.1 MB (57), HTML 297 KiB (1) and stylesheets 70 KiB (2). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.02 g of CO₂e: 122.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Headings skip levels (h3 → h5, h2 → h5 and h2 → h5), 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 only 38 characters: “Start Right. Govern Right. Build Trust”. 70 to 160 characters is enough to sell the click.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

The homepage links to 17 pages on firstblox.com and 9 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.

/services/foundations, /about-us and /lets-chat have no meta description, so Google writes the search snippet from whatever text it finds.

/request-a-scan has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 4 pages linked from your homepage 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: the server responded with a status of 400 ()”.

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

Large scripts ship without source maps.

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.

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.

firstblox.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.

firstblox.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.

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 1,233 words of visible text.

firstblox.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

firstblox.com has no SPF record, so mail servers can't tell which servers may send email as you. Your mail lands in spam more often, and anyone can send mail pretending to be you.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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

Opening the homepage sets 2 cookies (measured from a US location before any click).

Loading the homepage contacts 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
