altr.com website review

38 files block the first paint until they finish downloading. Deferring or inlining them could save about 5.0 s.

7 files are served with short cache lifetimes, so returning visitors download them again (225 KiB).

About 186 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.3 s faster on a phone.

Your mobile performance score is 61 (desktop: 98). Pages that score under 90 lose visitors before the first paint.

4 images could be 443 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

The page has 2,781 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

7 third-party services load with your homepage (Hubspot, cdn-cookieyes.com and lfeeder.com and others), adding 492 KiB and 170 ms of main-thread time.

7 KiB could be saved by minifying CSS.

2 long tasks block the main thread while loading, the longest for 74 ms. During a long task the page ignores taps.

About 24 KiB of CSS is downloaded but never applied on this page.

Desktop scores 98 but mobile only 61. A gap that wide usually means heavy scripts and images that hit phones hardest.

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.

Your largest element takes 12.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “ALTR Data Security Platform”.

The first text or image appears after 5.0 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 12.7 s. Good is under 3.8 s.

Visually, the page fills in at 5.9 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 2.1 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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 125 requests on a phone: images 994 KiB (20), scripts 818 KiB (43) and fonts 561 KiB (6). Under 2 MB keeps phones on slow connections fast.

1 image (35 KiB) is 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.71 g of CO₂e: 85.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 2 elements on the page fail this check, rated critical by axe-core.

Elements must only use permitted ARIA attributes: 7 elements on the page fail this check, rated serious by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 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.

There are 7 <h1> headlines (“Your Unified Data Security Platform”, “Enabling Secure, Scalable Data Sharing Across the…” and “ALTR Helps Q2 Control Data Security, Empower Inst…”). One clear main headline is easier for people and search engines.

The homepage links to 205 pages on altr.com and 28 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.

/why-altr, /use-cases/format-preserving-encryption and /use-cases/open-source-integrations have no meta description, so Google writes the search snippet from whatever text it finds.

/data-security-platform-buyers-guide, /why-altr, /product-tour, /solutions/data-protection-dashboard and /use-cases/open-source-integrations have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 49 found) and read each the way a search engine does.

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.

altr.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.

altr.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.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

Social proof on the homepage: 42 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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

Opening the homepage sets 5 cookies (measured from a US location before any click).

Loading the homepage contacts 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
