Monitoring built for agencies that manage client websites/shops
Stop reporting.
Start proving.
Your clients have no idea how hard you work.
Invisible work
You monitor, optimize, and fix, but none of it is visible to the client. When they can't see the value, they question the retainer.
Manual reporting
Compiling screenshots, metrics, and status updates into client reports eats hours every week, and it gets worse with every site you add. Time you could spend on billable work.
Reactive, not proactive
Without comprehensive monitoring, you find out about broken checkouts, expired certificates, and DNS issues when the client calls, not before.
Agencies lose clients they could have kept.
Not because the work was bad, but because the client never saw it. A client who can see uptime at >99%, performance scores climbing, and issues caught before they escalate doesn't just stay, they send referrals.

Monitoring data is a sales pipeline.
Every issue Vigilant detects is an opportunity to deliver more value. A slow webshop isn't just a low Lighthouse score, it's a performance optimization project. A broken product link isn't just a 404, it's an SEO fix your e-commerce client needs.
Lighthouse scores reveal optimization work
Vigilant tracks Lighthouse performance, accessibility, and Core Web Vitals over time. When a score drops below industry standards, you have a data-backed reason to propose an optimization sprint. No guesswork, no hard sell, just numbers that speak for themselves.
Broken links surface SEO quick wins
Vigilant crawls every page and sitemap to find broken links automatically. Each 404 is a concrete fix you can offer. Clients understand broken links, it's a visible problem with a clear solution. Bundle those fixes into a maintenance task and deliver fast, measurable value.
Security vulnerabilities create urgency
When Vigilant detects a CVE in a client's technology stack, that's not a nice-to-have fix, it's urgent. Security patches are the easiest work to justify and the hardest for clients to ignore. You become the agency that protects their business, not just builds their website.
Performance trends justify retainers
Uptime and latency data tracked over months tells a clear story. Show clients how response times crept up, or how a hosting change improved availability. Historical trends turn abstract "maintenance" into a concrete narrative that justifies ongoing investment.
The math is simple.
That's before counting the billable work each detected issue generates. Every alert is a conversation starter. Every report is a proposal in disguise. Vigilant pays for itself from the first month.

Let the data speak for you.
You promised 99% uptime. You optimized page speed. You fixed accessibility issues. With Vigilant, your clients don't have to take your word for it, they can see the proof themselves.
"You promised 99% uptime."
Now prove it.
Clients can open their dashboard or monthly report and see the uptime percentage right there. No more "trust me", the data confirms their site was online every single day. When you deliver on a promise and can prove it, renewals become automatic.
"Did the optimization actually work?"
Show, don't tell.
After a performance sprint or accessibility audit, your client can see the Lighthouse scores jump in their report or dashboard. Before and after, tracked over time. The work you did is no longer invisible, it's measurable progress your client can point to.
"The checkout works perfectly."
Verified regularly.
Flow monitoring runs through critical user journeys, checkout, registration, search, in a real browser, on a schedule. Your client can see in the report that their revenue-critical paths were tested and passing all month. That's peace of mind you can't fake.
Fix it before they notice.
The best agencies don't wait for clients to report problems. Vigilant watches infrastructure, security, and critical flows around the clock so you can resolve issues before they ever reach a customer.
Uptime monitoring
Vigilant checks every client's site from multiple regions around the world. The moment a site goes down, your team is alerted. Before clients notice, before customers leave, before revenue is lost.
Broken link crawler
Broken links silently damage SEO rankings and frustrate visitors. Vigilant crawls the entire site on a schedule, surfacing 404s, redirect chains, and dead resources before they cost clients traffic or conversions.
Lighthouse monitoring
Performance regressions rarely announce themselves. Vigilant runs automated Lighthouse audits on a schedule and tracks scores over time so you catch a slow deploy before it tanks conversion rates.
CVE monitoring
Vigilant scans thousands of packages daily and alerts you when a vulnerability affects your client's stack. You patch before attackers weaponize, and your client never knew they were at risk.
Certificate monitoring
An expired certificate shows visitors a browser security warning. Most leave immediately. Vigilant alerts you weeks in advance so you renew before anyone sees that padlock disappear.
DNS monitoring
A DNS misconfiguration or hijack can take a site completely offline in seconds. Vigilant monitors DNS records 24/7 and alerts you the moment something changes, before search engines even notice.
Flow monitoring
A broken checkout is invisible until customers stop buying. Whether your clients run Shopify, Magento, WooCommerce, or a custom webshop, AI-powered flow monitoring tests their critical journeys in a real browser, on a schedule. Describe the flow in plain English, no code required.
Health checks
Go deeper than "is it up." Monitor disk space, queue health, database connections, and application-specific metrics. With integrations for WordPress, Laravel, Magento, and more, detect silent failures before they cascade.
Smart notifications
Alerts on Slack, Discord, Teams, Telegram, email, and more. Route different alerts to different channels per client. Your team gets the right information on the right channel so nothing slips through.
Your clients call to say "the site is down." With Vigilant, you call them to say "we already fixed it."
View all featuresWhen the checkout breaks, revenue stops.
Your e-commerce clients lose money every minute something is wrong. A silent payment failure, a broken product page, a slow catalog, your clients won't notice until the monthly revenue report looks off. You should know first.
Test the full purchase journey
Flow monitoring walks through browse → add to cart → checkout → payment confirmation in a real browser, on a schedule. Whether your clients run Shopify, Magento, WooCommerce, or a custom platform, you'll know when the buy button stops working before a single customer complains.
Catch broken product pages at scale
A catalog with thousands of products means thousands of links that can break. Vigilant crawls every page and sitemap to find 404s, broken images, and dead links, across the entire catalog. Each broken product page is a lost sale your client never knew about.
Slow pages kill conversion rates
A product listing page that loads in 5 seconds instead of 2 can cut conversions in half. Lighthouse monitoring tracks performance across key pages over time, so when a plugin update, a new theme, or a heavy banner tanks load speed, you see the regression immediately.
Secure the storefront
An expired SSL certificate shows a browser warning on the checkout page, your client's customers leave immediately. CVE detection flags vulnerabilities in the shop's technology stack before attackers exploit them. Certificate and security monitoring keeps the trust signals intact.
Stay Vigilant.
Protect your clients before they even know there's a problem.
Professional reports. Zero effort.
Stop spending hours compiling screenshots and metrics. Vigilant generates polished PDF reports on a schedule you define, branded with your logo, and delivered straight to your client's inbox.
Choose what matters
Not every stakeholder needs every metric. Pick exactly which sections appear in each report: executive summary, uptime, performance, Core Web Vitals, broken links, flows, and certificate status. Build focused reports for technical teams or high-level summaries for clients.
Set it and forget it
Schedule reports weekly or monthly. Pick the day and time that works for your recipients. Vigilant generates the PDF and sends it automatically, no manual effort, no reminders, no forgotten deadlines. The schedule respects your team timezone, so reports arrive exactly when expected.
Your brand on every page
Add your logo, company name, address, and website. Every report looks like it came from your company, not ours.
Custom SMTP
Send reports from your own email domain. Your client sees your address in their inbox, not ours.
Multi-language
Set the language per report. English, Dutch, German, French, Spanish, Italian, and Polish, dates, labels, and content all translated.
Let clients answer their own questions.
"Is my site down?" "Why does it feel slow?" Instead of fielding these questions, give clients a branded dashboard where they can check for themselves. Real-time uptime, performance, and health data. One link, no login required.
"Is my site down?" they'll know before they ask
Clients check global uptime status, response times, and performance scores themselves. One secure link shows everything, from Lighthouse scores to certificate expiry. No more Monday morning "is it just me?" emails.
Clients see uptime, performance, and health data instead of asking you about it.
Uptime monitored from multiple regions. Clients see it's working worldwide, not just locally.
Token-protected URL. No accounts, no passwords, no setup for clients.
White-labeled
Your logo, company name, and website on every dashboard. Clients see your brand, not ours. Light and dark logo variants match the visitor's color scheme.
Auto-detected language
Dashboards detect the visitor's browser language automatically. Clients read data in their own language without asking you to translate anything.
Full control
Enable or disable any dashboard with one click. Revoke access instantly when a client relationship ends. Manage everything from a single overview.
Stay Vigilant.

Generic monitoring wasn't built for agency work.
You're probably duct-taping UptimeRobot, Google Lighthouse, manual spreadsheets, and a dozen browser tabs together. None of those tools generate client reports, offer branded dashboards, or turn monitoring into billable work. Vigilant does.
