Endpoint Alert vs DomainLens Pro

Tired of unexpected certificate expirations or sudden endpoint outages? Endpoint Alert helps you stay ahead by monitoring SSL/TLS certificates and endpoint health, sending deterministic expiry reminders and alerts when we detect connectivity, performance, or configuration issues so you can remediate quickly. NEVER MISS A RENEWAL Get deterministic push notifications before certificates expire — configurable reminders at 30, 14, 7, 3, and 1 day(s) — so you have time to renew and avoid avoidable downtime. WHAT WE CAN DETECT (REALISTICALLY) - Certificate expiry dates and chain/validation problems (missing intermediates, invalid chains, OCSP/CRL responses). - TLS handshake failures and common configuration issues. - DNS resolution errors and sudden DNS changes. - Endpoint responsiveness problems: timeouts, rising latency, and increased 4xx/5xx error rates from scheduled synthetic checks. - Functional regressions via synthetic transactions (if configured). KEY FEATURES - Unlimited Endpoint Monitoring: Add websites, APIs, and services — manage them from one dashboard. - Certificate Expiry Alerts: Deterministic reminders at configurable intervals. - Health Checks & Synthetic Transactions: Periodic uptime, latency, and content validation checks. - Trend & Anomaly Detection: Alerts on sustained latency increases or error-rate spikes that may indicate degradation. - Detailed Certificate Info: Issuer, validity period, SANs, chain details, and days until expiry. - Customizable Notifications: Push alerts and escalation settings so you only get notified when it matters. - Clean, Fast UI: Designed for clarity and scalability across many endpoints. WHO SHOULD USE THIS - Web Admins & DevOps: Streamline certificate and endpoint monitoring across services. - IT Teams: Maintain uptime and a reliable digital footprint. - Small Business Owners: Protect e-commerce and customer-facing services. - Agencies & MSPs: Manage multiple clients’ endpoints and certificates from one place. HOW THIS HELPS Endpoint Alert provides deterministically-timed certificate reminders and early detection of degradation signals. While not every sudden failure is predictable, these scheduled checks and trend-based alerts give you actionable early warnings so you can investigate and remediate before issues grow. Download Endpoint Alert now to keep certificates current and to receive timely alerts when endpoint health or certificate configurations show problems.

DomainLens Pro is a one-tap domain reconnaissance toolkit for IT pros, security analysts, developers, and anyone responsible for a domain. Type any domain, IP, or URL and DomainLens Pro runs 24+ specialized probes in two parallel phases, then aggregates the results into a single color-graded report. Browse it across ten organized tabs: • Overview — A–F security grade with a confidence score, top remediation actions, and per-category breakdown • DNS & WHOIS — A, AAAA, MX, NS, TXT, SOA records, TTLs, registrar, expiry, name servers, registration history • Identity (RDAP) — RFC 9083 lookup, abuse contact, EPP statuses, transfer history, privacy-redaction detection • SSL / TLS — full certificate chain, validity, signature algorithm, SANs, OCSP stapling, forward secrecy, and post-quantum readiness (X25519MLKEM768 / SecP256r1MLKEM768) • Headers — HSTS preload eligibility, CSP nonce/hash analysis, X-Frame-Options, COOP, COEP, Referrer-Policy, Permissions-Policy • Email — SPF strict alignment, DKIM key strength, DMARC policy + alignment, MTA-STS, TLS-RPT, BIMI, DANE, full mail-server diagnostics • Web Stack — server fingerprint, technology detection, third-party JS / dependency inventory, JS-derived endpoint discovery • Exposure — sensitive file probes (.git, .env, robots.txt), CORS misconfigurations, dangerous HTTP methods, exposed login portals • Infrastructure — ASN, hosting provider, cloud platform (AWS/Azure/GCP/Cloudflare), CDN/WAF detection, GeoIP, anycast detection, RPKI validation, IPv4 + IPv6 reachability • Intel — DNSSEC validation, CAA records, HTTPS/SVCB records, dangling CNAME detection, zone-transfer test, Certificate Transparency subdomain enumeration, DNSBL reputation, CVE lookup against detected tech via NVD, historical drift tracking Also handles: • IPv4 / IPv6 reverse-lookup mode — paste an IP, get the domain back • Private network mode — paste an internal RFC 1918 IP and get ICMP/HTTP/HTTPS detection, OS fingerprint by TTL, ARP MAC vendor lookup, traceroute (full on Mac; iOS sandbox limits some probes) • Scan history with one-tap re-scan, offline browsing, sync across devices via Google Sign-In • Versioned scoring algorithm with confidence weighting and partial-result handling for slow targets • Post-quantum TLS twin probe to verify hybrid key-exchange support Built for security pros: • Full TLS pinning to the scan backend • No analytics, no ad SDKs, no third-party tracking • Sign-in is optional — without it, no personal data ever leaves the device• When you do sign in, choose any of: Apple, Google, Microsoft, GitHub, or a one-time email code (no passwords, ever)• Native iPhone, iPad, and Mac Catalyst layouts with platform-appropriate menus and Cmd+1–9 keyboard shortcuts on Mac No subscription.
