Listing updated . Checked by MSP Software .
DefensX is a browser security platform from DefensX, designed for MSPs and enterprises managing client networks. The platform integrates directly into web browsers including Chrome, Firefox, Edge, Safari, Brave and Vivaldi without requiring proprietary software installation. It provides six layers of phishing defence, DNS-layer threat blocking, AI prompt protection, and zero-trust remote access capabilities.
The product is offered in tiered packages: Core, Core Plus, Premium and Premium Plus, each with increasing capability. Core provides foundational phishing and DNS protection with basic reporting. Core Plus adds data leak prevention and AI prompt safeguards. Premium includes browser isolation for sensitive tasks and advanced logging. Premium Plus delivers zero-trust network access that functions as a VPN alternative. Each tier includes Nexi, an AI agent that enforces compliance and protects against data misuse within AI tool interactions.
The platform supports advanced DNS security with threat intelligence feeds, custom allow and block lists, and per-site policy controls. It is suitable for MSPs managing multiple client environments through a multi-tenant dashboard, with roaming client protection for users working away from their office network. Pricing is quote-only and varies by tier and deployment scope, with no minimum commitment and flexible annual or monthly billing. The company allows cancellation at any time with no penalty. DefensX is based in New York. A free trial is not explicitly offered; contact the sales team to discuss trial and demo options. MSPs should verify which tier covers their specific DNS filtering, content filtering, AI protection and remote access requirements, and confirm how their existing RMM or PSA platform integrates with DefensX. The platform supports major browsers and operates entirely in the cloud (checked September 2026).
DefensX competes with Cloudflare Gateway, Cisco Umbrella, and Palo Alto Networks DNS Security in the DNS-filtering space, but differentiates by bundling browser security, AI governance, and zero-trust access. The emphasis on AI safety and data protection positions it for MSPs managing clients adopting AI tools. Pricing is quote-only; ask about per-user or per-endpoint pricing, implementation timeline and trial availability before committing. Confirm the feature tier covers your specific DNS blocking, content filtering, remote browser isolation and remote access requirements, and how it integrates with your RMM or PSA platform.

DefensX includes VPN-friendly DNS security with threat intelligence feeds, DNS-layer blocking of malicious domains, content category filtering, custom block and allow lists, per-site policy controls, and multi-tenant dashboard management for MSPs. The DNS protection is integrated into the browser security platform rather than as a separate appliance, providing roaming protection for off-network users.
The DefensX website does not explicitly state whether a free trial is available. Given the quote-only pricing model, MSPs interested in evaluating DefensX should contact their sales team to discuss trial or demo options before committing to a purchase agreement.
DefensX integrates directly into multiple web browsers including Chrome, Firefox, Edge, Safari, Brave and Vivaldi. The browser-based architecture means users do not need to install separate client software; security and DNS filtering are handled through browser extensions and native integrations.
DefensX documentation does not explicitly list specific RMM or PSA integrations. The platform is managed through its own multi-tenant console designed for MSPs. MSPs should confirm integration capabilities with their existing RMM or PSA systems before deployment to ensure compatibility with their management workflows.
