What Zorus does

Zorus is a US-based cybersecurity software company that builds device-based DNS web filtering and behavioral analytics tools purpose-built for Managed Service Providers (MSPs) and Managed Security Service Providers (MSSPs). Founded in 2017 and headquartered in Tampa, Florida (incorporated in Florida, with operating presence in Monroe, Connecticut), the company was acquired by DNSFilter in April 2025 after raising $9 million in Series A funding in December 2021 from Asymmetric Capital Partners, Innospark Ventures, and General Catalyst.

The company's core product is Zorus Filtering with CyberSight, which installs a local endpoint agent that inspects all internet-bound processes and applications on the device without requiring DNS rerouting, router changes, or network reconfiguration. Unlike traditional network-based DNS filters (Cisco Umbrella, WebTitan, WebRoot DNS), Zorus operates regardless of VPN, Active Directory, or custom DNS environments. The platform bundles device-based DNS filtering, Geo IP and network filtering, Zero Trust Device Isolation (added March 2024), SaaS inventory and usage monitoring, and the CyberSight behavioral analytics engine for insider threat, Shadow IT, and productivity reporting. A complementary network-level product, Zorus Network Security, was introduced in June 2023 for unmanaged devices.

Zorus monetizes exclusively through channel partners on a tiered per-endpoint annual subscription model (with a month-to-month option), with white-label block pages, portals, and reports that allow MSPs to present the platform as their own product. The company integrates directly with major RMM platforms (Datto, Kaseya, Syncro, ConnectWise Automate, Gradient MSP), supports HIPAA and CMMC compliance use cases, and positions itself as a simpler alternative to network-based filters that break client environments. Its customer base is composed of small and mid-sized MSPs and IT services firms (CMIT Solutions, Netwerks, Spidernet Technical Consulting, Thatch Computer Consulting, Tomorrow's Technology Today, Ekaru, Affinity Technology Partners, Impact Technology Group).

Direct peers

• DNSFilter: DNS-layer security provider also built for MSPs with content filtering and threat protection. DNSFilter was Zorus's direct competitor in MSP-targeted DNS filtering and acquired Zorus in April 2025 to add endpoint-based capabilities to its cloud-delivered security platform.
• TitanHQ (WebTitan): TitanHQ's WebTitan is a DNS/web filtering product sold heavily through the MSP channel. It competes head-on with Zorus on MSP-targeted filtering pricing and feature set, and is referenced on Zorus's own comparison pages.

Broad incumbents

• Cisco Umbrella: Cisco Umbrella (formerly OpenDNS) is a broad cloud-delivered DNS security platform with enterprise-grade threat intelligence. It competes with Zorus in MSP and enterprise filtering, and is directly referenced in Zorus's competitive comparison content.
• Sophos: Sophos offers DNS filtering, endpoint protection, and managed detection and response with strong MSP channel programs. It overlaps with Zorus in MSP-targeted web filtering and endpoint security workflows.
• Webroot (OpenText): Webroot DNS Protection is a cloud-based DNS filtering service widely deployed by MSPs. Zorus explicitly competes against Webroot's DNS offering in published comparison content.
• WatchGuard Technologies: WatchGuard offers DNSWatch and broader Unified Threat Management appliances with MSP-friendly licensing. It competes with Zorus in MSP-targeted DNS filtering and broader network security stacks.

Emerging players

• Huntress: Huntress is an MSP-focused cybersecurity vendor providing managed EDR, SIEM, and security awareness training. It targets the same channel buyer (MSPs serving SMBs) as Zorus and represents a natural adjacent security partner within MSP stacks.
• NinjaOne: NinjaOne is an MSP-native endpoint management and RMM platform. While not a direct DNS filtering competitor, it serves the same MSP buyer and increasingly bundles endpoint security, making it a competitive and adjacent ecosystem player.
• ThreatDown (Malwarebytes): ThreatDown by Malwarebytes delivers endpoint security and managed detection with a strong MSP channel program. It overlaps with Zorus on MSP-targeted endpoint security positioning and behavioral monitoring.

Others

• ConnectWise: ConnectWise provides PSA, RMM (Automate), and security solutions purpose-built for MSPs. As a strategic RMM integration partner of Zorus, ConnectWise is both a distribution channel and an ecosystem participant in the MSP security stack.
