Why it matters

Phishing starts in the browser — DefensX ends it there.

Password managers, email filters, and awareness training help — but attackers still live where users click, type, and sign in every day: the browser. DefensX adds a security layer exactly at that point.

AI is at work

Real-time page controls
Users can’t reliably spot a fake page especially on mobile or when rushed. With it's AI powered module Phisheye, DefensX evaluates and governs every session in real time, not just the URL.
  • 1Detects suspicious login flows and form behavior.
  • 2Restricts sensitive fields on untrusted pages.
  • 3Guides users with inline warnings, not pop-up fatigue.

Credentials & data leave the browser

Phishing-resistant UX
Credential harvesters abuse the same browser flows your apps use. DefensX wraps those flows in strong guardrails.
  • 1Protects passwords, tokens, and copy/paste operations.
  • 2Sanitizes DOM the prevent injection-type attacks.
  • 3Integrates with SSO & identity providers.

Security can’t slow the business

Built for adoption
Blocking the whole internet isn’t an option. DefensX lets users work normally while you quietly remove the sharp edges.
  • 1No full VPN tunnels to break SaaS and VoIP.
  • 2No heavy endpoint agent to maintain.
  • 3Same UX in-office, at home, or on BYOD.

Ads disguise threats

Malvertising blends into normal browsing and silently opens the door to phishing. DefensX removes those disguises before they reach the user.
  • 1Strips ad elements that impersonate trusted brands or services.
  • 2Cleans injected ad scripts that trigger silent redirects.
  • 3Blocks deceptive visuals that lure users into unsafe clicks.
How DefensX works

A phishing-aware browser session for every user.

DefensX turns a standard browser into a managed session: isolated when it needs to be, permissive when it can be — always watching for high-risk actions.

  • 1
    Users click like they always do
    Email, Teams/Slack, SMS, and ticket links all open inside a DefensX-governed browser session. No change to how they start their day.
  • 2
    DefensX classifies the session
    Reputation, page structure, login flows, and behavior all contribute to a session risk score — not just the domain name.
  • 3
    Risky flows get isolated & constrained
    Suspicious pages run in isolation: clipboard is limited, downloads are quarantined, and sensitive fields are protected or blocked outright.
  • 4
    Security team keeps end-to-end visibility
    Every click, decision, and blocked attempt is captured for investigation, reporting, and continuous tuning across your users and tenants.

Key capabilities

What makes the browser phishing-resistant.

A focused set of controls designed specifically for phishing and human-centric risk in the browser — not another generic web filter.

🧊 Smart isolation
Isolation is applied when risk is high, not for every single page — keeping performance smooth and user frustration low.
🔑 Credential & token protection
Keeps identity flows safe: phishing forms, token-stealing pages, and MFA fatigue workflows are governed at the browser layer.
📁 Safe downloads & uploads
Files are inspected and policy-controlled before they ever reach the endpoint — even on BYOD or unmanaged devices.
👁️ Human risk insights
See which users, teams, or tenants are most exposed to phishing attempts — and which controls actually reduce incidents.
🧩 Works with your stack
Integrates with existing email security, DNS filtering, SASE, and EDR — no rip-and-replace required.
🛠️ MSP & enterprise-ready
Multi-tenant management, templated policies, and reporting built for MSP practices and in-house security teams.
Who benefits

Designed for MSPs and security leaders.

Same core browser security — two different value stories, depending on whether you operate as an MSP or an in-house security team.

For MSPs

Multi-tenant control
  • ✓ Roll out phishing-resistant browsing as a standard service across all customers.
  • ✓ Use shared policy templates, then tune for high-risk tenants.
  • ✓ Pull tenant-level phishing and click-through reports for QBRs.
  • ✓ Position DefensX alongside your email security & DNS stack — not instead of it.

For security & IT leaders

Fewer incidents
  • ✓ Reduce phishing-related help desk tickets without blocking productivity.
  • ✓ Extend identity and data protection all the way into the browser session.
  • ✓ Gain visibility into high-risk behavior and near-miss events.
  • ✓ Use DefensX as a concrete control in audits, compliance evidence, and tabletop exercises.
FAQ

Common questions about phishing-resistant browsing.

A quick set of answers you can reuse in internal briefings, customer conversations, and security documentation.

Is this a new browser or an extension?
DefensX works as a controlled browser environment — depending on your deployment model, it can be accessed via a dedicated browser, a managed profile, or a seamless redirect for specific apps and flows.
Do users have to change how they work?
Not meaningfully. Links still open in a browser, SaaS apps still look the same, and performance remains smooth. The difference is that high-risk sessions get isolated and constrained without asking users to “be more careful.”
Does this replace email security or DNS filtering?
No — DefensX complements those layers. Email gateways and DNS filters reduce what users see; DefensX protects what they actually click, type, and download in the browser.
How fast can we pilot it?
Most organizations can start with a targeted user group — such as finance, executives, or high-risk teams — in days, not months. From there you can expand based on results and policy comfort.
