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 β€” configurable reminders at 30, 14, 7, 3, and 1 day(s) β€” 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 β€” 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.

About

DNS Sinkhole

Features
Read full description

Choose encrypted DNS without replacing your VPN. Sinkhole helps you understand, select, and configure a trusted DNS-over-HTTPS provider on iPhone and iPad. It adds an encrypted DNS configuration for the provider you choose, using the system API iOS provides for this. SIMPLE GUIDED SETUP Choose your goal β€” privacy and security, family protection, or advanced custom DNS β€” then follow clear installation steps designed for everyone. CURATED PROVIDERS Compare privacy and security-focused options from established public DNS providers. Depending on your selection, provider-side filtering may cover known malware, phishing, trackers, ads, or adult content. ADVANCED MODE Use a trusted custom HTTPS DNS endpoint from a service you control or configure, including compatible self-hosted resolvers. HONEST STATUS Sinkhole reads its own state from iOS: whether a configuration exists, and whether iOS has it active. It also sends a single DNS test request to confirm the selected endpoint is reachable, and keeps that separate from activation. PRIVACY BY DESIGN β€’ No Sinkhole account β€’ No LorisLabs DNS server β€’ No VPN tunnel and no VPN configuration β€’ No advertising or analytics SDK β€’ No DNS query or browsing history received by Sinkhole Once active, DNS requests go directly from your device to the provider you selected. That provider's privacy policy and filtering behavior apply. Sinkhole cannot see or fabricate per-domain statistics. IMPORTANT iOS asks for your approval before Sinkhole can add a DNS configuration, and only you can select it in Settings > General > VPN & Device Management > DNS. You can switch away or remove it there at any time, without the app. A VPN may choose to override system DNS settings; behavior depends on that VPN.
