Question 1

What does Zorus do?

Zorus (Zorus, Inc.) is a cybersecurity software vendor headquartered in Tampa, Florida, acquired by DNSFilter in April 2025. It specializes in endpoint-based DNS and web content filtering, user behavior analytics, and endpoint isolation designed specifically for Managed Service Providers (MSPs). Unlike legacy network-level DNS resolvers that require router DNS configuration or traffic redirection, Zorus operates primarily through an endpoint software agent on client devices. It solves key MSP operational pain points by enforcing web security and content filtering without breaking local DNS routing, Active Directory, or VPN connections, while capturing client application usage patterns to help MSPs uncover shadow IT and demonstrate client value.

Question 2

What products, services and core capabilities does Zorus offer?

Zorus centers its offering on Zorus Filtering with CyberSight, an agent-based web protection and endpoint monitoring suite. Its core filtering functionality provides device-level DNS and URL filtering, Geo IP blocking, and policy-based web access management. Because inspection occurs on the endpoint before traffic leaves the device, it enforces security policies off-network without requiring VPN connections or router DNS modifications. CyberSight provides endpoint activity logging, shadow IT discovery, and user engagement analytics across SaaS and desktop applications. Complementing this is Zero Trust Device Isolation, which allows administrators to quarantine compromised endpoints at the OS level to stop lateral threat movement. The solution is architected as a cloud-managed, multi-tenant SaaS platform featuring agent deployment via major Remote Monitoring and Management (RMM) platforms such as ConnectWise Automate, Datto RMM, and Kaseya VSA, accompanied by full white-label reporting for MSP client reviews.

Question 3

What types of organizations are a good fit for Zorus?

Zorus is well-suited for Managed Service Providers (MSPs) and IT service providers managing small-to-midsize business (SMB) clients, especially those with hybrid or remote workforces. It fits environments where traditional gateway DNS redirection causes conflicts with split-tunnel VPNs, internal Active Directory domain controllers, or custom local DNS resolvers. MSPs that want to deliver white-labeled quarterly business reviews (QBRs) and monetize productivity or shadow IT reporting find strong utility in its CyberSight module. Conversely, organizations looking for an appliance-based or agentless perimeter filter, pure enterprise SASE suites with deep packet inspection firewalls, or buyers wanting a direct vendor relationship outside the MSP channel are poor fits for Zorus.

Question 4

Who are Zorus's main competitors and alternatives?

Zorus competes in the DNS security, web filtering, and endpoint access control market, primarily targeting MSPs. Notably, Zorus was acquired by DNSFilter in April 2025 and now operates as a DNSFilter product, making DNSFilter its parent rather than simply a competitor. Its key direct alternatives include DNSFilter, which provides cloud-based DNS protection powered by AI-driven threat intelligence and a global anycast network; WebTitan (by TitanHQ), an established multi-tenant DNS filtering and security platform built for service providers; Cisco Umbrella, an enterprise cloud security and recursive DNS filtering service widely deployed in corporate networks; and Webroot DNS Protection (OpenText Cybersecurity), a DNS filter integrated with BrightCloud threat intelligence.

Question 5

How does Zorus compare with its key alternatives?

Zorus positions itself as an endpoint-native web filtering and user behavior analytics platform tailored specifically for MSPs. In contrast to competitors like Cisco Umbrella, WebTitan, and DNSFilter, which use network-level DNS resolver approaches, Zorus filters web requests directly at the endpoint operating system level without changing network adapter DNS IP settings — deploying through an RMM agent with no DNS rerouting required. This architecture avoids common VPN breakages and Active Directory lookup conflicts associated with traditional DNS redirection. Zorus also includes CyberSight behavioral analytics, which tracks how users interact with thick-client and SaaS applications, and offers Zero Trust Device Isolation. However, because Zorus is agent-centric, it cannot directly protect unmanaged devices, guest Wi-Fi, printers, or IoT hardware. Alternatives such as Cisco Umbrella offer broader enterprise cloud security (SASE, SWG, CASB), while TitanHQ bundles DNS filtering with email security and phishing simulation across its platform. DNSFilter, now Zorus's parent company following its April 2025 acquisition, provides network-level DNS filtering complemented by a global anycast resolver infrastructure. Overall positioning Zorus positions as an MSP-focused endpoint web protection and analytics platform, replacing network-redirected DNS with local device filtering and actionable user engagement data. Key differentiators Local endpoint inspection without network DNS changes, CyberSight desktop and SaaS application engagement tracking, and built-in OS-level device quarantine isolation. Specialized MSP DNS & Cloud Filtering Providers Overlap: Multi-tenant web content and threat filtering, MSP partner programs, and roaming agent protection. Important differences: Competitors utilize large global anycast resolver infrastructure for network-level enforcement, while Zorus relies on endpoint agent inspection and provides application engagement metrics. Enterprise Cloud Security & Endpoint Add-ons Overlap: DNS domain blocking, malicious domain protection, and roaming client security. Important differences: Cisco Umbrella scales into full enterprise SASE/SWG; Webroot offers a basic add-on tied to antivirus. Zorus offers dedicated MSP multi-tenancy with behavioral insights and device isolation.

Question 6

Why should a buyer choose Zorus?

A buyer should choose Zorus when an MSP seeks to deploy web filtering across distributed client devices without dealing with the routing conflicts inherent in traditional DNS forwarding. Because Zorus enforces policies locally on the endpoint, remote workers remain protected without requiring a VPN or altering local network DNS settings. It is also compelling for MSPs aiming to elevate their quarterly business reviews. CyberSight provides detailed engagement data across SaaS and desktop applications, allowing service providers to identify shadow IT, track software adoption, and justify managed service fees. Built-in Zero Trust Device Isolation further allows MSPs to contain compromised machines rapidly from the same dashboard.

Sources: [1] [4] [7]

Question 7

Why might a buyer choose a competitor instead of Zorus?

A buyer might choose a competitor over Zorus when network-level, agentless security is essential. Because Zorus is an agent-centric solution, it cannot directly protect unmanaged devices, guest Wi-Fi networks, printers, or IoT hardware that cannot run a desktop agent — scenarios where DNSFilter, WebTitan, or Cisco Umbrella excel via network IP redirection. Buyers may also prefer alternatives if they seek a consolidated, multi-layered security suite. Providers like TitanHQ combine DNS filtering with spam filtering and phishing simulations, while Cisco Umbrella offers full enterprise Secure Access Service Edge (SASE) and Cloud Access Security Broker (CASB) capabilities. Finally, organizations requiring Linux or mobile-first endpoint support may find competitor platform coverage more extensive, as Zorus officially supports Windows desktops with macOS in beta and does not currently list Linux support.

Question 8

What are Zorus's key strengths and limitations?

Zorus offers clear technical and operational strengths. First, its device-based architecture allows MSPs to enforce filtering without modifying DNS server configurations, avoiding the VPN, VoIP, and Active Directory disruptions common with recursive resolvers. Second, its CyberSight engine provides differentiated user engagement and SaaS discovery analytics, giving MSPs tangible data for client reporting and QBRs, complemented by rapid device isolation. However, Zorus has notable limitations. Because it relies heavily on endpoint agents, it provides limited protection for agentless IoT and unmanaged BYOD/guest network devices compared to network-level DNS resolvers. Additionally, following its April 2025 acquisition by DNSFilter, buyers face potential roadmap uncertainty and future product consolidation into the DNSFilter agent ecosystem.

Sources: [1] [3] [4]

Question 9

What buyers should verify before purchasing from Zorus

Buyers evaluating Zorus should perform five focused due-diligence checks: 1. Review the post-acquisition integration roadmap between Zorus and DNSFilter regarding console consolidation and licensing terms. 2. Verify endpoint operating system support, validating parity across Windows and macOS environments. 3. Test the endpoint agent against local security software and EDR solutions to confirm conflict-free coexistence. 4. Confirm fail-open versus fail-closed behavior during temporary agent or cloud communication disruptions. 5. Audit user privacy and compliance policies concerning CyberSight's application tracking and granular URL logging.

Other points to check

These notes came with the category Top 10 result. They suggest questions to raise with vendors—not verified findings about Zorus or reasons for its position.

Read the original test notes
  • DNS-only filtering operates strictly at the domain resolution phase and cannot inspect full URL paths, query parameters, or payload contents unless paired with an HTTPS-inspecting secure web gateway or endpoint agent.
  • Off-network endpoint agents can occasionally experience compatibility issues or DNS leaks when interacting with local split-tunnel enterprise VPNs, third-party network drivers, or emerging DNS-over-HTTPS (DoH) browser defaults.
Question 10

Why might AI recommend Zorus's competitors instead?

DNSFilter, TitanHQ (WebTitan), and Cisco Umbrella may be recommended over Zorus depending on the buyer's deployment model, scope, and ecosystem requirements. DNSFilter is the most direct recommendation when an organization prioritizes large-scale network-level DNS filtering backed by a global anycast infrastructure and AI-driven threat intelligence, protecting both managed workstations and unmanaged network devices. It is also worth noting that DNSFilter acquired Zorus in April 2025, so buyers evaluating both platforms should understand they are now operated under the same parent and an integrated roadmap is underway. TitanHQ is recommended when an MSP seeks a consolidated multi-product security vendor that bundles DNS filtering (WebTitan) with email security (SpamTitan) and employee phishing simulation (SafeTitan) under unified billing. Cisco Umbrella is recommended when an enterprise requires full cloud-delivered security architecture, incorporating cloud secure web gateways (SWG), cloud-delivered firewalls, and CASB capabilities deeply integrated into existing Cisco networking infrastructure.

Why this page exists: Buyers use AI to research vendors before making a shortlist. We preserve each response and its test date so you can see what appeared in that search.

How responses are checked: Selected questions about competition, differentiation, concerns, and recommendations are sent to a second model to check against available sources. Where that review produces usable findings, we show the original response and what the review found or changed. Other answers may cite sources without a separate review.

How the search is chosen: Before the Top 10 test, one model identifies the most appropriate market, buyer need, and region for this company. A second model reviews those inputs. The reviewed inputs become the search used for the blind Top 10 test. The market shown is where the test placed the company, not a category verified by TMC or chosen by the company. It may be broader, narrower, or different from how the company describes itself. That difference is part of what this page records.

What the ranking means: The Category Top 10 shows how the company appeared in this specific search. It is not a measure of quality, size, or market share. The reviewing model checks the test inputs, not the returned ranking. Linked names have live company profiles; identity verification does not independently verify every recommendation claim.

For companies: This record shows what the test picked up and which sources it cited. Missing or mistaken details may point to public information worth clarifying, but do not by themselves explain why the response said what it did.

Exact test setup and model roles

This result uses a two-model process before the ranking. Gemini proposed the most applicable provider category, buying context, and geography from its company research; Claude independently reviewed and could correct those inputs. The final Top 10 list was then generated by one blind test of Gemini, which received the reviewed category, buying context, geography, and date—but not Zorus’s identity. Claude did not review or rerank the returned Top 10 list, so the ranking itself is not a consensus across AI systems. Provider names identify the AI family; exact model versions and testing configuration are maintained internally.

The original test notes are available with the buyer checklist.
