DNS Doctor

DNS Doctor is an email deliverability and DNS health scanner for small businesses, agencies, and MSPs. Paste a domain at dnsdoctor.dev and you get an instant report covering SPF, DKIM, DMARC, MX, general DNS, blacklist status, and domain and SSL certificate expiry. The scan is free and requires no signup. What makes DNS Doctor different is how fixes are generated. Every recommended record comes from a deterministic engine that follows the published RFC grammar and validates the result, including the SPF 10-lookup limit. The AI layer only explains problems in plain English. It never writes the record itself, so you never paste a guessed record into your DNS. Nothing is changed automatically. You review every record and apply it yourself at your DNS provider. The paid Monitor plan adds continuous checks for up to 10 domains, DMARC aggregate (RUA) report ingestion with 12 months of history, and email alerts for record changes, verdict regressions, new sending sources, blacklist listings, and upcoming domain or SSL expiry, at a flat $12 per month. DNS Doctor also works with AI assistants. The same diagnostics are available through an MCP server and published plugins, with the same rule: records come from the validating engine, never from the model.

inCompass

inCompass is a web intelligence and content categorization solution designed to classify URLs, domains, and IP addresses for use in security, networking, and analytics applications. It is typically embedded into OEM products such as secure web gateways, firewalls, DNS filtering platforms, and endpoint security solutions. The platform evaluates web traffic and returns structured metadata, including primary and secondary content categories, security classifications (such as malware or phishing), reputation scores, and age-based content ratings. These outputs can be used to support policy enforcement, threat detection, compliance controls, and reporting. inCompass can be deployed in multiple architectures depending on performance and infrastructure requirements. A local deployment embeds the full categorization database within the application for low-latency lookups. A cloud deployment performs lookups via a remote service. A hybrid model combines a local database of high-frequency destinations with cloud lookups for broader coverage. The solution includes software development kits (SDKs) and APIs that allow applications to submit URLs or IP addresses and receive categorization results in real time. It supports different matching methods, including domain-level and full-path URL analysis, and can return multiple classification attributes for a single request. The underlying datasets are updated on a continuous basis, with full database updates and incremental changes delivered regularly to ensure current coverage of web content and threat indicators. inCompass also supports optional features such as custom category definitions, user-managed allow/block lists, and alternative taxonomies (for example, IAB categories for advertising use cases), enabling integration into a variety of application environments.
