Janice, are we selling poison on the website?”

“Gift” means poison in German. Your store has been selling it for 3 months. Cassian™ would have caught it on day one.

The problems you don't know you have

You're losing customers right now. You just don't know it yet.

Every day, store owners discover issues that have been costing them sales for weeks — sometimes months. Here's what Cassian™ finds within minutes.

Translation

Your moisturiser is called "Morning Mist." Your German customers read "Morning Manure."

Machine translation doesn't understand context. Your best-selling skincare product might be telling international customers something revolting.

That product page gets 2,000 visits a month from Germany. Every visitor who reads "Mist" sees "Manure."

Broken links

Your top product page has been 404ing for 3 weeks. Nobody told you.

You deleted an old collection but the link is still in your navigation, your email footer, and 14 product descriptions.

That page was getting 800 visits a month. At a 3% conversion rate, that's 24 lost orders you'll never see.

Data mismatch

Your admin says "In Stock." Your storefront says "Sold Out."

Your Shopify admin and your live storefront are telling different stories. No scraper can find this — because scrapers can't see your backend.

Cassian™ connects to your store and compares what you think you're selling with what customers actually see. This is what no other tool can do.

SEO

12 of your product pages have the exact same meta description.

Copy-paste happens. But Google doesn't index duplicate content well, and your customers can't tell your products apart in search results.

Those 12 pages are competing against each other instead of ranking individually. That's 12x the organic traffic you're leaving on the table.

Is your store OK?

Cassian Sentinel™ · Order Pulse

“Site is up” doesn't mean “store is selling.”

A broken payment gateway. A misconfigured shipping zone. A checkout bug after a theme update. Your site stays up. Your store stops selling. You find out hours later.

Order Pulse monitors your checkout health every hour. It compares actual orders against your store's historical patterns and alerts you the moment something breaks — not when a customer complains.

This alert fires for all tiers — including free. Because if your checkout is broken, you need to know. Now.

Cassian Shield™

Your store deserves enterprise security.

Cross-site scripting. Clickjacking. Missing security headers. Exposed admin endpoints. The vulnerabilities that keep security teams up at night — and most store owners have never heard of.

Cassian Shield runs the same OWASP ZAP scanning used by Fortune 500 security teams. Automated. Continuous. Translated into plain English so you know exactly what matters and what to fix first.

Cassian Sentinel™ · Uptime

Your SSL expires in 22 days. Your domain expires in 9.Do you know that?

Uptime monitoring is table stakes. Cassian Sentinel goes further — it watches your SSL certificate expiry, your domain registration expiry, and your response times. The things you forget about until they take your store offline at 2am on a Saturday.

Checks every 1–5 minutes. Confirms before alerting. No false alarms. When Cassian Sentinel says your store is down, it's down — and you know within minutes, not hours.

Cassian Sentinel™ checked your store 847 times in the last 24 hours.

“The domain registration for mystore.com expires in 9 days (6 March 2026). If it lapses, your entire store goes offline — and someone else could register it. Renew now.”

Cassian Sentinel checks your domain registration and SSL certificate on every health check. You get 30 days' warning — not a 2am surprise.

Most stores are doing better than they think.

Here's the thing — every audit tool leads with problems found. Cassian™ leads with confidence given. Your first scan will probably tell you your store is in good shape. And if it finds something worth fixing, you'll be glad you checked.

Status before issues. Confidence before action. Always.

Built for busy founders

You don't know what you don't know.

Running a Shopify store is a full-time job. Cassian™ is the colleague who watches everything you can't.

You're too busy to check

You're managing inventory, running ads, answering support tickets, and shipping orders. Checking every page on your site for broken links and bad translations? It's not happening. Cassian™ does it for you, every single day.

You can't see what customers see

Your Shopify admin shows you one thing. Your storefront might show something completely different. Different prices, different descriptions, different stock levels. You'd never know unless a customer complains — or leaves.

You sell internationally but can't read every language

You've translated your store into French, German, Spanish. But did the translator catch every nuance? Is that product description accidentally offensive? You can't check — but Cassian™ can.

SEO tools overwhelm you with jargon

"Canonicalization error on paginated collection template." What does that even mean? Cassian™ tells you in plain English: "Your summer collection page isn't showing up in Google. Here's the fix."

Every lost customer costs more than you think

A broken link isn't just annoying — it's revenue you'll never recover. A mistranslation isn't just embarrassing — it destroys trust. The cost of not knowing is invisible until Cassian™ makes it visible.

You want permission to stop worrying

That's really what this is about. You want to know your store is OK — and if it's not, you want someone to tell you exactly what to fix. That's Cassian™. Peace of mind, delivered every Monday at 8am (UTC).

AI search readiness

Is your store visible to AI?

ChatGPT, Perplexity, Google AI Shopping — they're already recommending products to buyers. But they can only recommend stores with the right structured data.

Fewer than 1 in 4 Shopify stores have sufficient structured data for AI shopping assistant citations. Most store owners don't even know this matters yet. Cassian™ checks your AI readiness in every scan.

Compounding value

The longer you use Cassian™, the more valuable it becomes.

Every scan is stored. Every score change is tracked. Every screenshot is kept. Most tools treat each visit as a blank slate. Cassian™ builds a complete picture of your store's health over time — and that picture only gets richer.

After 12 months, you'll have a complete history that no other tool can replicate. Not because we lock you in — because the value accumulates.
