Comodo Secure DNS

Comodo Secure DNS routes DNS requests through redundant security servers to filter threats and manage web access. Its cloud infrastructure uses load balancing and Anycast, with servers in more than 25 countries. The service is designed to block phishing, malware domains, malicious sites, botnets, spyware, and other web-borne attacks. Administrators can filter more than 80 content categories, build blacklists and whitelists, and set policies by company, location, endpoint, mobile device, IP, subnet, or user. The page says millions of new domains are added every two hours. Protection for roaming devices extends beyond company networks, and iOS and Android apps cover cellular and Wi-Fi connections. Reporting can be customized in real time or scheduled by email; administrators can also brand block pages and tailor messages by category. Gold is free for enterprises and MSPs, with up to 300,000 DNS requests per month. It does not support Active Directory. Separate Platinum packages add features including encrypted DNS, internal network policies, and, for MSPs, multi-company management.

Comodo Secure DNS combines threat blocking, domain filtering, and remote-device coverage. Gold is free but has request and feature limits; Platinum options are listed without prices.

It is intended for enterprises and managed service providers that need DNS filtering and visibility for users and devices on and off their networks. The Gold plan may suit organizations that can work within its request limit and Active Directory restriction.

Comodo Secure DNS is a cloud service that filters DNS traffic and blocks web threats for organizations. It is best suited to enterprises and managed service providers that need centrally managed protection for office and roaming devices. Gold gives smaller deployments a no-cost starting point, but its monthly request cap and missing internal-network controls limit its reach.

Overview

Comodo resolves DNS requests through redundant, load-balanced Anycast infrastructure hosted in more than 25 countries. It blocks phishing, malware domains, malicious sites, botnets, spyware, and other web-borne attacks. The distributed cloud infrastructure is a fit for organizations protecting users across locations without relying on a single on-site resolver.

Filtering spans more than 80 content categories, and millions of new domains are added every two hours. Administrators can create custom blacklists and whitelists and set policies by company, location, endpoint, mobile device, IP, subnet, or user. That level of control suits organizations with varied teams and sites, though Gold excludes internal IP and subnet policies as well as internal IP visibility.

Key features

• Threat protection: Comodo says its Threat Research Labs draws on 85 million analysis nodes in more than 190 countries. The service uses this threat intelligence to block a wide range of web-borne attacks.
• Roaming-device coverage: Off-network protection follows users and devices wherever they connect to the internet. The iOS and Android apps protect over both cellular networks and Wi-Fi, which makes the service relevant to organizations with mobile staff.
• Reporting and block pages: Real-time customizable reporting and scheduled email reports give administrators ongoing visibility. They can also add a company logo and tailor block-page messages by category.
• Enterprise integration: Gold does not support Active Directory. Platinum can bypass selected domains to internal DNS servers for Active Directory sites, and the MSP edition adds multi-company management in one dashboard.

Pricing

Gold includes 24×7 email support, as do all packages, but its 300,000-request monthly ceiling makes it a constrained choice for larger or busier deployments. It is a sensible way to start without a subscription cost if its feature exclusions are acceptable. Platinum is the relevant step up for internal-network controls, encrypted DNS, or virtual appliances; MSPs managing multiple clients also gain a shared dashboard. The Platinum plans have a 1 month trial option, while Gold is free. No renewal terms are stated.

Platforms

Comodo Secure DNS supports Android, iOS, Linux, macOS, web, and Windows. The mobile apps extend protection to cellular connections as well as Wi-Fi; platform support alone does not remove Gold’s plan limits.

Who it's for

Choose Comodo if your enterprise or MSP needs DNS-based threat blocking, category filtering, and policy management across locations and roaming devices. Gold is most appropriate when the 300,000 monthly requests and lack of internal-network controls are enough. Organizations that need Active Directory routing, encrypted DNS, internal IP visibility, or virtual appliances should consider Platinum instead.

Pros and cons

• Pro: More than 80 filtering categories, custom lists, and policy controls by user, device, location, and network segment support differentiated rules.
• Pro: Off-network coverage and iOS and Android apps extend organizational protection beyond office networks.
• Pro: Platinum adds internal-network policies, encrypted DNS, and virtual appliances; MSP Platinum also centralizes multiple companies.
• Con: Gold stops at 300,000 DNS requests per month and excludes several controls that matter to organizations with internal networks.
• Con: Active Directory support requires Platinum, so Gold is not a fit for organizations that need internal DNS bypasses for AD sites.

Alternatives

DNS Filtering Software is a useful starting point for comparing services in this category. Consider AdGuard DNS if open-source code inspection matters; its free plan and broader platform range include API and self-hosted support. NextDNS is a better fit for readers seeking a free tier with 300,000 monthly queries, unlimited devices and configurations, and all features, though it has no free trial.

NxFilter suits readers who want freeware for commercial or non-commercial use, with an optional paid Jahaslist Monthly plan at $7 a month. Quad9 is a simpler free DNS service for anyone who wants no contract or sign-up. RethinkDNS is worth considering for an Android user seeking a free, open-source app. OpenDNS FamilyShield is the straightforward choice for preconfigured adult-content blocking without sign-up.

AdGuard is another freemium option for readers comparing device-protection software. CleanBrowsing may suit those who need a paid Basic plan with up to 25 devices or 3.75 million requests per month and more than 26 custom filters; its listed price is $8.99 a month.

Verdict

Comodo Secure DNS is a strong fit for enterprises and MSPs that want cloud DNS threat blocking, granular filtering, and protection for roaming devices. Gold’s free entry point is useful for modest request volumes, but the cap and missing internal controls are meaningful constraints. Choose Platinum when internal-network policies, encrypted DNS, virtual appliances, or MSP multi-company management are requirements; otherwise, compare simpler free alternatives before committing to Comodo’s organization-focused approach.
