Welcome to Monx - Your Gateway to Seamless WebApp Monitoring!

With Monx, you gain real-time insights into your web application's health, performance metrics, and potential issues. Our cutting-edge monitoring tools provide actionable data, allowing you to identify and address issues before they impact your users.

Global uptime checking

Worried your site might go down? We have servers worldwide that will report any problem as soon as it happens. Be the first to know when your site is unavailable.

Broken page & content detection

We crawl and index your entire website, just like Google. As soon as we detect a broken link on your site, we'll notify you. This includes error pages like "page not found", "internal server error" and even "mixed content".

Continuous certificate monitoring

We check all your SSL certificate expiration dates & alert any change we detect. We give you actionable & user friendly alerts so you know what to fix.

Domain Patrol

Continuous security and hygiene scans on every domain you enroll. No agents, no SDKs, no config.

Web hardening

HTTPS upgrade and HSTS, security headers (CSP, X-Frame-Options, nosniff), TLS version and cipher audit, insecure-cookie detection, and redirect-chain analysis — the everyday hygiene most teams forget to recheck.

Email authentication

SPF strictness, DKIM selector discovery, DMARC policy and reporting, MX configuration — everything that decides whether your transactional mail lands in inboxes or spam folders.

Attack surface

Subdomain enumeration via certificate-transparency logs and subfinder, port scan with service fingerprint, tech-stack identification, CVE matching, and Nuclei templated vulnerability scans across every asset we discover.

Reputation & trust

RBL/DNSBL blacklist checks, VirusTotal reputation, privacy-policy and cookie-consent presence, and AI-extracted business-legitimacy signals from your public pages — the trust posture buyers and partners actually look up.

Performance

Lighthouse audits with First Contentful Paint, Largest Contentful Paint, Total Blocking Time, and Cumulative Layout Shift. TTFB and connection-duration breakdown per region. Trend over time, not a one-shot snapshot.

AI assistance

Per-finding mitigation code snippets generated for your stack. Trust-signal extraction reads your homepage and legal pages. Self-hosted Ollama runs by default; OpenAI and Anthropic are opt-in fallbacks, not required.

Security & Privacy

We scan from inside our network, so we hold ourselves to the same bar we audit you against.

SSRF defense-in-depth

Every domain you enroll is rejected at signup if it resolves to a private IP. Every scan re-validates DNS before connecting, and our HTTP transport re-validates on every redirect hop — closing the DNS-rebinding window most monitoring tools leave open.

Modern web headers

HSTS with two-year max-age and includeSubDomains, Content-Security-Policy with strict frame-ancestors, X-Frame-Options DENY, X-Content-Type-Options nosniff, Referrer-Policy and Permissions-Policy on every response. We eat our own cooking.

Credentials & sessions

bcrypt-hashed passwords, current-password gate on every change, session rotation on auth events, rate-limited login and verification flows with constant-time comparisons. A stolen cookie doesn't escalate to account takeover.

CSRF & injection

Double-submit cookie CSRF with Origin verification on every state-changing request. All SQL is parameterized; Jinja2 autoescape is on for every template. Any LLM-generated content is HTML-escaped before render.

Secrets at rest

API keys, bot tokens, and webhook secrets are Fernet-encrypted in the database. Stripe webhooks verify HMAC signatures and use Redis SETNX for replay protection. Telegram callbacks are HMAC-signed end-to-end.

Customer data control

Per-domain toggles for AI-powered checks; when self-hosted Ollama is used no scan content leaves our perimeter. Account deletion is honored end-to-end across MySQL, ClickHouse, and Redis — no orphaned rows.

Integrations

Alerts that land where you're already paying attention. Per-monitor routing, severity-based, mutable from the chat client.

Telegram

Full bot integration. Receive incidents in any chat or group. Acknowledge, mute, and query monitor status without leaving the conversation. HMAC-signed callbacks prevent replay.

Slack

Rich-formatted incident threads with severity color-coding, response-time graphs, and inline action buttons. Channel-per-environment or per-team routing supported.

Email & webhooks

Verified per-recipient SMTP delivery with optional daily digest rollups. Or wire raw JSON to any HTTPS endpoint with HMAC-signed payloads for your own pipeline.
