Most breaches don't start on the network anymore. They start with a login page.

Customer portals, partner platforms, APIs and internet-facing business applications have become the front door into the enterprise, and they're exactly where modern attackers begin. Yet for most organisations, web application testing still sits in its own silo, separate from identity, cloud and infrastructure validation, answering "is this vulnerable?" rather than "what could an attacker actually do with it?"

Horizon3 has just closed that gap with NodeZero WebApp, and we're pleased to say it's now part of what we offer here at Cyber Vigilance.

‍

What it does:

NodeZero WebApp tests your custom, business-critical applications the way a real attacker would, not the way a scanner does:

• Crawl - headless-browser discovery finds every route, hidden function, SPA and API endpoint, including the parts legacy scanners and static site maps miss.
• Authenticate - it logs in as a real user and tests business logic and workflows behind the login, not just the anonymous pages in front of it.
• Attack - starting read-only and graduating to deeper testing as confidence grows, it safely chains business logic, access control and session weaknesses into proven, exploitable outcomes.
• Prove - every finding comes with replayable proof: request/response logs, screenshots and route-level context, so your team can verify exactly what happened and fix it faster.
• Repeat - it runs continuously against your full application estate, not once a year, so you see what's newly exposed or newly fixed release over release.

Why it matters:

A vulnerability on its own rarely tells you much. The real question is what it leads to. Because NodeZero WebApp connects into the same platform as NodeZero's identity, cloud and infrastructure testing, a web application finding doesn't stop at the app boundary. You get to see whether it opens a path to compromised credentials, cloud resources or your core business systems, and whether that path was actually closed after remediation, not just patched on paper.

That's the shift NodeZero WebApp represents: from "we found a vulnerability" to "we proved attackers can't use it."

Getting started

If your web applications haven't been validated this way before, or your last pentest is already out of date the moment it's delivered, this is worth a look. We can talk you through where NodeZero WebApp fits alongside your existing testing and how quickly it can be stood up against your estate.
