💸 What it costs you
How much does one hour of downtime cost you?
On an online shop, every unmonitored minute costs you cold cash. Here's the real bill for a silent incident — the kind nobody notices, until the Stripe payout drops.
1,800 €
lost on average for 1 h of broken checkout on a PrestaShop with 100 orders/day. Without alerts, it can drag on all night.
230
confirmation emails never sent in 24 h when the cron stops.
−42 %
of Google traffic within 48 h on an expired SSL that went unnoticed.
🚨 Detected issues
10 incidents we detect before your customers (and before Google)
An unpatched plugin flaw, an expired certificate, a malware injection at night: what really kills an e-commerce shop is infrastructure and security. Here's what KLN scans continuously on your PrestaShop or WooCommerce.
Expired SSL certificate
Validation every 6 h. Alerts at 30, 14 and 7 days before expiry. Avoids the red "Connection not secure" screen that scares away 100 % of buyers.
Vulnerable plugin / module (CVE)
We cross-check your stack against Wordfence Intelligence and Friends-of-Presta every day. Public flaw on one of your plugins = you know the same day, before the bots.
Injected malware / defacement
Daily HTML scan: eval()+base64, crypto miners, hidden iframes, suspicious redirects. Hash diff: we see if your shop was modified overnight.
Blacklisted IP (Spamhaus, etc.)
Spamhaus ZEN, Barracuda, SpamCop, SORBS, UCEProtect, PSBL. Listed IP = your confirmation emails land in spam. Checked daily.
Site flagged "dangerous" by Google
Red Chrome page "The site you're trying to reach is dangerous" = −100 % conversion in 1 h. We poll the Google Safe Browsing API continuously.
Degraded mobile performance
Google PageSpeed Insights + Core Web Vitals every day: LCP, FCP, CLS, TTFB. LCP > 4 s on mobile = up to −40 % conversion and Google demotion.
Saturated server (CPU, RAM, disk)
The KLN module reports CPU, RAM, disk and load average. Default thresholds: CPU > 90 %, RAM > 90 %, disk > 85 %. You know before it cracks under load.
Broken DNS / missing record
Resolves A, AAAA, MX, NS, CAA records every 6 h. A missing MX = your emails stop sending. An A pointing to an old IP = unreachable shop.
Outdated CMS version
Unpatched PrestaShop 1.7.x or WordPress = open door for known exploits. Automatic version detection, notification on every core security release.
Is your shop exposed to any of these 10 threats?
We'll run a free audit of your PrestaShop or WooCommerce in 24 h. No commitment.

🆚 KLN vs alternatives
Why a generic tool isn't enough.
UptimeRobot and Pingdom run an HTTP ping and tell you you're "up". But what about when your Contact Form 7 has a critical CVE, your IP is on Spamhaus, or your certificate expires in 6 days? KLN covers infrastructure + security, not just uptime.

💬 They trust us
What online merchants say.
« We avoided 3 nights of downtime this quarter. At 1,200 €/h on our business, that pays for the tool 50 times over a year. »
« My WooCommerce cron had been stuck for 36 h with not a single alert. 230 confirmation emails never sent, 47 angry customers on support on a Monday morning. Since KLN, the same incident is detected in 8 minutes — straight to my Slack. »
« We run 24 shops for our clients. Before KLN, we'd find out about outages from an angry client email on Monday morning. Now we step in before they even notice — result: −68 % support tickets in 4 months and 2 contracts renewed on that argument alone. »
