threatlocker.com website review

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 13.3 s.

About 1.5 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 5.7 s faster on a phone.

About 402 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.8 s faster on a phone.

21 files are served with short cache lifetimes, so returning visitors download them again (526 KiB).

Your mobile performance score is 28. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.2 s on main-thread work while loading, 2.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,678 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Google CDN, website-files.com and Google Tag Manager and others), adding 6.4 MB and 2.0 s of main-thread time.

Google CDN costs a phone 812 ms of main-thread work and 1.5 MB 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.

19 images could be 769 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

website-files.com costs a phone 385 ms of main-thread work and 3.8 MB 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.

Google Tag Manager costs a phone 316 ms of main-thread work and 376 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.

Hubspot costs a phone 217 ms of main-thread work and 438 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.

20 long tasks block the main thread while loading, the longest for 245 ms. During a long task the page ignores taps.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

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.

The first text or image appears after 20.6 s on a phone. Good is under 1.8 s.

Your largest element takes 28.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Book a demo Request more info”.

Visually, the page fills in at 20.6 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 31.0 s. Good is under 3.8 s.

Scripts block taps and scrolling for 947 ms in total while the page loads. Good is under 200 ms.

The layout shifts by 0.151 while loading, so content jumps under the reader's thumb. Good is under 0.1.

4 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' largest content (lcp) went from 2.4 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 8.4 MB in 147 requests on a phone: scripts 3.3 MB (29), fonts 1.9 MB (27) and images 1.8 MB (42). Under 2 MB keeps phones on slow connections fast.

6acfe73ab58114159937ac12_ThreatLocker_Judgement Day_Website_ is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 2.38 g of CO₂e: 286.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 13 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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.

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

Headings skip levels (h2 → h4, h4 → h6 and h4 → h6), which makes the page harder to scan with a screen reader.

There are 3 <h1> headlines (“Zero Trust solutions for AI, Endpoints, Cloud, an…”, “” and “”). One clear main headline is easier for people and search engines.

Structured data found (Corporation and Organization) but with 1 problem, for example “Organization: missing name”.

The homepage links to 177 pages on threatlocker.com and 18 external pages.

https://www.threatlocker.com/platform-archive declares the homepage as its canonical URL, which tells Google it is a copy of the homepage and keeps it out of search results. A site-wide template setting usually causes this.

https://www.threatlocker.com/why-threatlocker/community is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/ and https://www.threatlocker.com/platform-archive all use the title “Enterprise Cybersecurity Solutions | ThreatLocker”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.threatlocker.com/capabilities has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 74 found) and read each the way a search engine does.

2 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

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

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 2,544 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager and The Trade Desk (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 10 cookies, 2 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 35 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
